Efikasi Asap Cair Dari Limbah Pengolahan Industri Gondorukem Pada Kayu Karet Terhadap Rayap Kayu Kering (Cryptotermes cynocephalus Light.) Ghani Fakkar Ihak Sumardi Suhaya, Yoyo wood vinegar dry-food termite durability Wood vinegar is made from condensation of biomass pyrolysis, contained phenolic compound, carbonyl, and acid that used for insecticide, wood and food preservative, and aroma enhancer. Pine waste as biomass obtained from gum rosin and turpentine processing had a great potential to be processed into wood vinegar. This paper studies the effect of coating rubber wood using wood vinegar made from pine waste against dry-wood termite. The rubber wood (2.5x2.5x5 cm3) was coated with distillated and without distilled (crude) wood vinegar in 100, 50, and 25% dilution. Samples were conditioned within in hours before PVC pipes (2.6 cm diameter and 5 cm height) were installed into wood surface using wax. There were 50 drywood termite fed into the pipes. The samples kept in dark room for 12 weeks. This experiment was conducted according to SNI 01-7207-2014. The result showed that coating method using un-distilled or crude wood vinegar made from pine waste could increase the durability of rubber wood against dry-wood termite. This happened due to the toxic compound in the crude wood vinegar that made coating methods using un-distilled wood vinegar can be used to increase the durability of rubber wood against dry-wood termite.

Kebisingan, Tingkat Konsentrasi Dan Persepsi Pekerja Penggergajian Kayu Di Pt. Erika Mila Bersama, Sumatera Utara Muhdi, Muhdi Syahputri, Yopita Manurung, Harisyah bandsaw concentration ear protection noise sawmills Factories usually have several machines to carry out the production process. When working, the machine usually makes a sound due to the use of a bandsaw machine. The aims of this study were to measure the intensity of bandsaw noise, to analyze the effect of bandsaw noise on the concentration level of sawmill workers, and to analyze the effect of noise on workers’ perceptions of sawmills at PT. Erika Mila Bersama, North Sumatra. Measurements were made on 2 bandsaw machines while operating to determine the noise intensity. The concentration test was carried out using a nonparametric test, namely the Wilcoxon test to determine the effect of engine noise on the respondent’s concentration level when using ear protection and without ear protection. Perception test was analyzed using the Linkert scale to determine perception. The results showed that the bandsaw machine noise intensity on machine A and B were 103.22 dB and 104.93 dB respectively. The noise of the band saw machine showed a significant effect on the concentration level of the respondents in the operator of the band saw machine with the two treatments given, while the non-operator respondents showed that the noise had no significant effect on the two treatments given. Perceptions of operators and non-machine operators on noise without ear protection are the same, namely very noisy. After using the earmuff, the machine operator’s perception becomes less noisy and the non-operator’s perception becomes quite noisy. Then when using the earplug the machine operator’s perception is quite noisy and the non-operator’s perception is noisy. The benefit of this research is that it can provide information regarding occupational health and safety regarding the level of concentration of workers on noise and the influence of workers’ perceptions of noise levels and used as evaluation material for companies in carrying out noise control measures at PT. Erika Mila Bersama, North Sumatra.

Kualitas Dan Preferensi Konsumen Terhadap Madu Lebah Apis Mellifera L. Dan Apis Dorsata F. Suhesti, Eni Roni, Yogi Yanti, Rina Novia Ningsih, Ambar Triatna Hadinoto karakteristik kualitatif madu Madu ternak Nektar ekstra floral Sifat fisikokimia madu Uji hedonik The availability of honey for the people of Indonesia is met by harvesting in nature from Apis dorsata (A. dorsata) bees and livestock bees. One of the bees that is often bred is Apis mellifera (A. mellifera). Consumer considerations in choosing honey are largely determined by the quality and their preferences for the honey. This paper evaluates: 1) the quality of honey from A. mellifera and A. dorsata bees according to the standard of SNI 8664-2018, 2) the comparison of consumer preferences for the two types of honey. Honey samples were taken from harvesters in Sungai Rawa Village, Sungai Apit District, Siak Regency, and packaged in sealed bottles. The honey quality testing method is guided by SNI 8664-2018. The comparison of consumer preferences was carried out using the hedonic method using 50 panelists. The comparison of the quality of each type of honey in accordance to the SNI was descriptively analyzed. Consumer preferences were compared using a two-sample t-test. The results showed that only ash content and water-insoluble solids in A. mellifera honey met the requirements of SNI 8664-2018. Meanwhile, acidity, ash content, and water-insoluble solids of A. dorsata honey met the quality requirements of the standard. Consumer preference was higher for A. mellifera honey for color and viscosity, but for aroma, A.dorsata honey had a higher preference. Meanwhile, the taste variable and the overall level of consumer preference did not differ between the two types of honey.

EVALUASI KEKUATAN ORIENTED STRAND BOARD (OSB) BAMBU ANDONG PADA BERBAGAI RASIO LAPISAN FACE-CORE BERDASARKAN PENGUJIAN NON-DESTRUKTIF DAN DESTRUKTIF: Evaluation of Andong Bamboo Oriented Strand Board (OSB) Strength Made of Different Face-Core Layer Ratio through Non-destructive dan Destructive Testings Ningsih, Rima Vera Karlinasari, Lina steam lapisan face-core MOEd stress wave velocity Oriented strand board (OSB) merupakan produk papan komposit struktural yang dapat dibuat dari bahan berlignoselulosa seperti kayu dan bambu. Penelitian ini bertujuan untuk mengevaluasi hubungan antara pengujian non-destruktif metode kecepatan gelombang bunyi (stress wave velocity, SWV) dan pengujian destruktif ((modulus of elasticity, MOE) dan modulus of rupture, MOR)) OSB yang terbuat dari strand bambu andong (Gigantochloa verticillata Munro). Strand bambu diberi perlakuan steam dengan cara memasukkan strand bambu ke dalam autoklaf pada suhu 126°C dan tekanan 1,4 kg/cm2 selama 1 jam. Perekat yang digunakan adalah fenol formaldehida (PF) dengan kadar 8% dan penambahan parafin sebanyak 1% berdasarkan berat kering oven strand bambu. OSB dibuat tiga lapisan yaitu lapisan inti tegak lurus strand bambu terhadap lapisan muka pada berbagai rasio lapisan muka:inti (face:core:face) papan yang berbeda (25:50:25, 27,5:45:27,5, 30:40:30, 32,5:35:32,5, 35:30:35, dan 37,5:25:37,5). Nilai SWV dihitung menggunakan waktu rambatan gelombang dan digunakan untuk mengukur nilai modulus elastis dinamis (MOEd). Hasil penelitian menunjukkan bahwa semakin tinggi komposisi lapisan permukaan (face) pada arah sejajar panjang strand bambu dapat meningkatkan sifat mekanis papan OSB. Komposisi rasio lapisan face-core mempengaruhi sifat mekanis papan (MOE, MOR, SWV, dan MOEd). Terdapat hubungan yang baik antara pengujian non-destruktif berbasis gelombang bunyi dengan pengujian destruktif yang menggunakan model regresi linear.

Penilaian Organolpetik Dan Analisis Keamanan Sediaan Lipstik Berbahan Dasar Lemak Tengkawang Gusti, R Esa Pangersa Pasaribu, Gunawan Tri Sandi Dahlian, Erik lipstik tengkawang uji organoleptik uji cemaran mikroba uji iritasi Tengkawang fruit can be processed into a form of high economic value fat. This is due to its properties which are similar to cocoa butter so it is widely used as Cocoa Butter Substitutes (CBS) on various cocoa fat products, one of which is lipstick. Manufacturing and analysis of the performance of tengkawang fat-based lipstick has been done. However, to ensure a cosmetic product is safe to use, it is necessary to use safety and irritation tests. This study aims to analyze the safety level of the tengkawang fat-based lipstick through an organoleptic test, microbial contamination, and simple irritation test. There are four lipstick formulations used in this activity, the two best formulations (m3 and m5) from the previous year's research, two modification formulas of the previous formula (m3i and m5i) and commercial lipstick as a comparison (control). Organoleptic tests will be carried out on four types of lipstick formulas which include texture, gloss, odor, color and spreadability of the lipstick. This test uses a scoring system. panelists for the organoleptic test were 34 people with an age range of 17-45 years. Another analysis is the microbial contamination and simple irritation tests following the procedures of the Indonesian National Standard (SNI) 16-4769-1998 concerning lipstick. The microbial contamination test was carried out in two stages, the first for fresh lipstick (finished production) and the second for lipstick that had been stored for four months. A simple irritation test analysis was carried out by applying lipstick to the mice's skin. The results showed that from an organoleptic point of view, the lipstick with the formula m5 was the most preferred by the panelists. In terms of safety for use, the microbial contamination test showed no presence of microbes in the lipstick preparation. A simple irritation test showed no signs of irritation after 24, 36, 48, and 136 hours of observation, which indicated that the lipstick made from tengkawang fat was safe to use.

Kinetic Study Of Palm Oil Catalytic Cracking Over A Zeolite-based Catalyst Wargadalam, Verina Januati Aminuddin Syafei, Muhammad H.G. Enrico, Josiah palm oil catalytic cracking kinetic model A study on catalytic cracking of palm oil (RBDPO) over an equilibrium zeolite-based catalyst to produce gasoline fraction was carried out. The effect of contact times between the feed and catalyst was studied by experimenting with WHSV in the range of 6 h-1 to 25 h-1, and the effect of catalytic reaction temperatures was observed at 490 °C, 510 °C, and 530 °C. The results show that yields of gasoline fraction tend to decrease with the decrease of WHSV, due to “over-cracking” of gasoline fraction into gaseous products. A four-lump kinetic model consisting of gasoline fraction, gaseous products, and coke was applied to derive sets of reaction rate equations. A numerical method was used to estimate the kinetic parameters.   BRIN Publishing 2023-07-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/1000 10.55981/jphh.2023.1000 Jurnal Penelitian Hasil Hutan; Vol. 41 No. 2 (2023): Jurnal Penelitian Hasil Hutan 2442-8957 0216-4329 10.55981/jphh.v41i2 eng https://ejournal.brin.go.id/jphh/article/view/1000/580 Copyright (c) 2023 Verina Januati Wargadalam, Aminuddin, Muhammad H.G.

PEMANFAATAN ASAP CAIR LIMBAH GERGAJIAN KAYU PINUS SEBAGAI BIOPESTISIDA DALAM MENGHAMBAT SERANGAN HAMA PENGGEREK BUAH KOPI (Hypothenemus hampei Ferr.): Utilization of Liquid Smoke from Pine Wood in Inhibiting the Attacks of Coffe Fruit Press (Hypothenemus hampei Ferr.) Hadiyane, Anne Navila, Aviva Karliati, Tati Pari, Gustan Darmawan, Saptadi Rumidatul, Alfi Biopesticide biorefinery liquid smoke PBKo pests phenol Sawmill waste is a waste product that needs to be put to use. Applying biorefinery principles through pyrolysis technology, which produces liquid smoke, is one of the innovative efforts to utilize sawmill waste. Chemical compounds contained in the liquid smoke have the potential to act as biopesticides. Therefore, this study aimed to test the ability of liquid smoke from pine sawmill waste to fight PBKo (Hypothenemus hampei) pests on coffee plants. Pyrolysis produced the liquid smoke at 400–450 °C for 4–7 hours. The observed parameters were the physicochemical characteristics and efficacy of liquid smoke biopesticides at concentrations of 1.5%, 2%, and 2.5% against PBKo pests through pest attack tests, toxicity tests, and repellency tests. The results showed a total phenol value of 7248.01 mg GAE/100g. The results of the GC-MS analysis of the liquid smoke, which has the potential to be an insecticidal compound toxic to coffee fruit borer pests, are acetic acid, phenol, alcohol, furan, cycloalkane, cyclohexane, alkene, eugenol, and guaiacyl acetone. Based on the stydy’s results, liquid smoke from sawn pine wood waste at a concentration of 2.5% has the potential to be a natural biopesticide for inhibiting the growth of PBKo pests on coffee plants.     BRIN Publishing 2024-04-19 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/1985 10.55981/jphh.2024.1985 Jurnal Penelitian Hasil Hutan; Vol. 42 No. 1 (2024): Jurnal Penelitian Hasil Hutan; 17-30 2442-8957 0216-4329 10.55981/jphh.v42i1 eng https://ejournal.brin.go.id/jphh/article/view/1985/3612 Copyright (c) 2024 AUTHORS https://creativecommons.org/licenses/by-sa/4.0

SIFAT-SIFAT PEREKAT TANIN FORMALDEHIDA DARI BAGIAN CABANG BAKAU HITAM (Rhizophora mucronata) : Properties of Tannin Formaldehyde Adhesive Made of Part of Branches Wood of Black Mangrove (Rhizophora mucronata) Nuryawan, Arif Ritonga, Lia Anggraini Basyuni, Mohammad Risnasari, Iwan Susilowati, Arida bagian cabang bakau hitam ekstraksi perekat tanin formaldehida Rhizophora mucronata tanin Bakau hitam (Rhizophora mucronata) yang tumbuh di hutan mangrove bermanfaat dalam menahan abrasi dan tempat berkembangnya biota laut. Untuk mempertahankan fungsi ini dan supaya hutan mangrove tetap lestari, hanya bagian kayu cabang yang dimanfaatkan. Penelitian ini bertujuan untuk mengevaluasi bagian cabang bakau hitam untuk diekstraksi kandungan taninnya sebagai bahan baku perekat kayu. Pada penelitian ini dibedakan asal taninnya, yaitu dari bagian kulit, kayu, dan campuran kulit dan kayu yang diperoleh melalui ekstraksi menggunakan panci presto (pressure cooker) pada tekanan 10-15 psi selama 30 menit pada suhu 116-121°C. Metode sintesis meliputi pengeringan, konversi, ekstraksi tanin, pembuatan perekat tanin formaldehida, dan karakterisasi perekat tanin, yang meliputi kenampakan, pH, viskositas, berat jenis, kadar solid, waktu gel, dan kandungan emisi formaldehida. Hasil ekstraksi tanin menunjukkan rendemen tanin yang diperoleh pada ekstraksi kulit (9,32%) > kulit+kayu (5,95%) > kayu (3,28%). Oleh karena itu pembuatan perekat tanin formaldehida dan karakterisasinya berdasarkan Standar Nasional Indonesia 06–4567–1998 untuk resin phenol formaldehyde (PF) hanya dilakukan pada rendemen yang tertinggi yaitu kulit.  Penampakan perekat tanin formaldehida asal kulit yang dihasilkan berupa cairan berwarna merah terang kehitaman, agak kental, terdapat butiran/kotoran, dan pH-nya 10,18 (basa). Kekentalannya 70,6 cps, berberat jenis 1,137, kadar solid 27,54%, periode gel 44 menit, dan kandungan formaldehida bebasnya 5,04%. Berdasarkan hasil penelitian ini dapat disimpulkan: 1) bagian cabang bakau hitam (R.mucronata) yang memiliki kandungan tanin tertinggi ada pada bagian kulit; 2) ekstraksi tanin menggunakan panci presto bisa diterapkan sehingga menghemat waktu ekstraksi; 3) Sifat-sifat perekat tanin formaldehida yang dihasilkan mirip dengan perekat PF hanya lebih encer.  BRIN Publishing 2023-12-05 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/2564 10.55981/jphh.2023.2564 Jurnal Penelitian Hasil Hutan; Vol. 41 No. 3 (2023): Jurnal Penelitian Hasil Hutan; 149-156 2442-8957 0216-4329 10.55981/jphh.v41i3 eng https://ejournal.brin.go.id/jphh/article/view/2564/1903 Copyright (c) 2023 Arif Nuryawan, Lia Anggraini Ritonga, Mohammad Basyuni, Iwan Risnasari, Arida Susilowati https://creativecommons.org/licenses/by-sa/4.0

EFFECTIVENESS OF PINE SAP COLLECTING TOOLS BASED ON SIEVER VARIATION IN IMPROVING THE QUALITY OF PINE SAP HARVESTING Jumini, Sri Abdul Hanan, Ishaq Khotimah, Khusnul Arsyad, Muaddiul Indratama, Andin inclined plane container quality pine resin filter variation Perhutani continues to improve the quality of pine sap harvest through the coakan method and the innovation of containers right under the sap drips. However, the quality produced is still less than optimal. Based on this, a pine sap container based on a filter was made that can improve the quality of the harvested pine sap. This study aims to determine the effectiveness of the pine sap container based on variations in filters and inclined planes on the tapping gutter. The study was conducted using an experimental method to obtain the mechanical advantage parameters of an economical pine sap container that can increase the productivity of the tool's performance based on the concept of an inclined plane. Testing was carried out in the laboratory to design and measure the mechanical efficiency of the tool, and field observations were continued to evaluate the quality and productivity of the pine sap produced. Data collection was carried out by systematically measuring the mass of sap, the angle of inclination of the gutter, and the mechanical parameters of the tool. The experiment showed that the largest mechanical advantage parameter value was found in the tapping gutter with the largest angle of inclination, namely 70°. In addition, this tool, with an innovative filter-based design and optimal angle of inclination, has been proven to improve the sap quality and minimize dirt and water pollution. The results of this study indicate that the developed tool is effective in increasing the efficiency of harvesting and the quality of pine sap, which is in line with the research objective to optimize the process of collecting pine sap. The tool produced by the researcher is a semicircular bowl-shaped container equipped a lid that can prevent dirt and rainwater from entering so that good-quality sap is obtained. This tool can improve the quality of sap with a higher purity level while producing harvesting efficiency of up to 25% compared to traditional methods, so this innovation has the potential to be an effective solution to increase the productivity of pine sap harvests sustainably.

PENINGKATAN KUALITAS GONDORUKEM DENGAN VARIASI KONSENTRASI TERPENTIN PADA PENCUCIAN GETAH PINUS Syaifuddin, Afif Sa'diyah, Khalimatus Prasetya, Desta Enggar Dwi gum rosin pine sap quality turpentine Gum rosin, commonly called gondorukem, is a product derived from processing pine sap, possessing significant potential for international market competition. However, the demand for exports from Indonesia has decreased annually due to the gondorukem's quality not meeting market standards. This study investigates the impact of turpentine concentration in the pine resin washing process on the quality of the produced gondorukem. The research was conducted in two stages: sap purification and distillation. In the sap purification process, 1250 grams of pine sap were dissolved using turpentine at 80°C, with varying turpentine concentrations of 27.5%, 28.5%, 29.5%, 30.5%, 31.5%, 32.5%, and 33.5%. This was followed by adding 5% oxalic acid, precipitation for 30 minutes, washing with distilled water, and separation. The washed oleo pine resin, weighing 1100 grams, was then distilled at 175°C for 2-3 hours. Results indicate that higher concentrations of turpentine lead to increased acid value, softening point, and color scale, resulting in purer and darker gondorukem. However, adding turpentine tends to reduce yield while causing fluctuations in nonvolatile parameters. The highest quality gondorukem was obtained at a turpentine concentration of 29.5%, with the following specifications: acid value of 191.24 mg KOH/gram, color scale of 6.9 (WW quality), softening point of 79°C, nonvolatile content of 99.23%, and yield of 75.08%.

The characteristic of tannin potentially affects the quality of tannin-based adhesive. The addition of extender and hardener also influences the quality of tannin adhesive. In this study, we investigated the characteristics of Acacia mangium tannin extract produced from bark obtained from various locations in Indonesia, as well as the bonding quality of tannin adhesive with the addition of an extender and hardener. The objective of this research was to understand the difference in mangium tannin characteristics from different locations and the effect of extender and hardener addition on the bonding strength of acacia tannin adhesive. The Acacia mangium wood barks were obtained from Parung Panjang, Probolinggo, Pontianak, and Muara Enim. The amounts of extender and hardener added were 0%, 2.5%, 5%, 7.5%, 10%, and 0%, 0.5%, 1%, 1.5%, 2%, respectively. The evaluation of mangium tannin bark extract was conducted using the solid content and stiasny number tests. The bonding strength of the tannin adhesive was evaluated through shear strength and wood failure tests of sengon laminated wood. The two-ply sengon laminated wood was fabricated under the following conditions: a glue spread rate of 170 g/m², a cold-press time of 24 hours, and a pressure of 12 kg/cm². Mangium tannin bark extract from Parung Panjang has the best characteristics for adhesive production, i.e., 5.70% solid content and 200.63% stiasny number. The extender and hardener amounts of 7.5% and 1.5%, respectively, produced optimum properties for dry shear strength and wood failure, which meet the JAS No. 234 requirement, i.e., 112.31 kg/cm² and 98–100%, respectively.

RELASI ANTAR KARAKTERISTIK MAKROSKOPIS PADA BATANG BAMBU KUNING DAN SERO (Macroscopic Characteristic Relationships on Kuning and Sero Bamboo Culm) Liliefna, Leonard Dantje Siruru, Herman Budiman, Ismail diameter karakteristik makroskopis ruas tebal dinding Ukuran karakteristik makroskopis bervariasi menurut arah panjang batang bambu. Bambu kuning dan bambu sero memiliki ukuran panjang ruas dan tebal dinding batang yang sangat berbeda, sehingga penting untuk mempelajari bentuk sebaran karakteristik makroskopisnya, serta mengetahui bagaimana batang bambu mempertahankan keseimbangan antar karakteristik makroskopisnya terhadap berat tajuknya sendiri dan terpaan angin. Selain itu, dibutuhkan model untuk mengestimasi proporsi panjang batang bambu yang memenuhi ukuran tebal dinding minimum pada pembuatan bambu lamina. Karena terdapat variasi panjang batang antar contoh uji, maka digunakan normalisasi jarak dari pangkal batang sebagai variabel panjang batang. Tujuan penelitian ini adalah mendeterminasi bentuk sebaran karakteristik makroskopis, menggunakan rasio antar karakteristik makroskopis untuk mengetahui bagaimana batang bambu mempertahankan keseimbangan antar karakteristik makroskopisnya terhadap berat tajuknya sendiri serta terpaan angin, dan membangun model hubungan antara tebal dinding dan normalisasi jaraknya dari pangkal batang guna mengestimasi besarnya proporsi panjang batang bambu yang memenuhi ukuran minimum pada pembuatan bilah bambu. Metode analisis regresi polinomial digunakan untuk memodelkan hubungan antar variabel. Hasil penelitian menunjukkan bahwa bentuk sebaran karakteristik makroskopis serta rasionya (D/R, td/D, td/R) pada jenis bambu kuning dan bambu sero memiliki bentuk hubungan yang non-linear. Pada bagian pangkal hingga ke bagian tengah batang, nilai rasio tersebut menurun, sedangkan pada bagian tengah hingga ke bagian ujung, batang bambu cenderung mempertahankan besarnya rasio tersebut relatif konstan dengan sedikit menanjak ke bagian ujung. Model polinomial yang diperoleh untuk hubungan antara tebal dinding (td) dan normalisasi jaraknya (X%) untuk jenis bambu kuning adalah , dan untuk jenis bambu sero adalah.

PERCEPTION OF THE USEFULNESS OF CONTAINER DEVICES BASED ON SIEVE VARIATIONS ON THE QUALITY OF PINE SAP HARVESTING Abdul Hanan, Ishaq Jumini, Sri Khotimah, Khusnul Arsyad, Muaddiul Indratama, Andin Pine resin collection tool usability forest products filter variations Open pine resin containers in the form of coconut shells and plastic bowls cause the quality of pine sap to decrease, and it is difficult to obtain premium quality, because of the ingress of dirt. The impurities are in the form of leftover twigs, dry pine leaves, grass, soil, and gravel. In addition, when the wind easily releases the coconut shell because the binding is not strong enough with the pine tree. The shell’s pores are finally easily eroded by rain due to the sawing process. Open containers (without covers) are very susceptible to producing less pure pine sap because they are mixed with impurities that fall into the container. They will be difficult to decompose if the dirt is small because the impurities can easily pass through the filter. This study aims to determine the perception of the usefulness of a container tool based on filter variations on the quality of pine resin harvesting. The study was conducted with a quantitative descriptive approach. Data collection was carried out using a questionnaire technique that was given to users, namely pine farmers. Data analysis was carried out using descriptive statistics, namely calculating the average of the results of the questionnaire recapitulation. The study results showed that the community agreed that the farmers can use the innovation of a pine sap container based on a sieve in harvesting pine sap. The tool has good durability, is easy to maintain, is easy to use, practical, effective use, ; is safe, is easy to store, does not produce waste, and has excellent benefits and functions. The impact of using this tool is that Perhutani no longer needs to look for tools, and the quality of the pine sap harvested with this sieve-based pine sap container is no longer in doubt. With good quality harvested pine sap, the income of the pine sap farmer community has increased BRIN Publishing 2025-05-17 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/9157 10.55981/jphh.2025.9157 Jurnal Penelitian Hasil Hutan; Vol. 43 No. 1 (2025): Jurnal Penelitian Hasil Hutan; 41-48 2442-8957 0216-4329 10.55981/jphh.v43i1 eng https://ejournal.brin.go.id/jphh/article/view/9157/8892 Copyright (c) 2025 Ishaq Abdul Hanan, Sri Jumini, Khusnul Khotimah, Muaddiul Arsyad, Andin Indratama https://creativecommons.org/licenses/by-sa/4.0

Efek Asap Cair Gelam (Melaleuca sp) sebagai Pengawet terhadap Berat Kayu dan Berat Jenis Terantang (Campnosperma auriculatum (BI.) Hook.f) Alpian, Alpian Samosir, July Sarana Dame Yanciluk Tanduh, Yusintha Silvianingsih, Yosefin Ari Supriyati, Wahyu Luhan, Gimson asap cair gelam terantang berat kayu berat jenis penyimpanan luar ruangan Terantang is commonly found growing in the peat swamp forests of Central Kalimantan. It holds significant economic value in the wood processing industry; however, it has low durability, requiring preservation treatments to enhance its wood quality. This study aims to analyze the impact of Gelam wood liquid smoke concentration and the radial direction of Terantang wood on its physical properties, particularly wood weight and specific gravity, after being stored outdoors under shaded conditions for 5 weeks. A factorial Completely Randomized Design (CRD) was employed, incorporating two factors: liquid smoke concentration (0%, 10%, 20%, and 30%) and radial direction of the wood (near the bark, middle, and near the pith). The data were analyzed using ANOVA, followed by Tukey’s HSD test to determine significant differences between treatments. The results indicated that increasing the concentration of liquid smoke significantly enhanced both the wood weight and specific gravity. The 30% liquid smoke concentration produced the highest increase in specific gravity (0.5240 g/cm³). The radial direction of the wood also had a significant effect, with the near-pith section showing higher specific gravity. The interaction between liquid smoke concentration and radial direction significantly influenced the wood weight. These findings suggest that Gelam wood liquid smoke is an effective natural preservative that can significantly maintain the physical quality of Terantang wood stored outdoors under shaded conditions for 5 weeks, specifically in terms of wood weight and specific gravity. This method shows potential for use in sustainable wood processing industries.

Plants of the Myrtaceae family are well known for producing essential oils, and Syzygium is one of its prominent genera. Species from this genus, namely Syzygium polyanthum (Salam), S. myrtifolium (Pucuk Merah), and S. aqueum (Jambu Air) are common plants that are widely cultivated as ornamentals, spices, and fruit-bearing species, and they possess significant potential as sources of essential oils. This study aimed to determine (1) the yield of essential oils from the leaves of three Syzygium species, and (2) to identify the chemical components of the obtained essential oils. The leaves of the three species were distilled using steam and water distillation to extract essential oils. The oil yield was calculated, and its chemical constituents were analyzed with GC-MS. The results showed that the highest essential oil yield was obtained from S. aqueum (0.167%), followed by S. polyanthum (0.080%) and S. myrtifolium (0.061%). The essential oil of S. myrtifolium contained the greatest number of compounds (65), followed by S. aqueum (46 compounds) and S. polyanthum (18 compounds). The main constituents of S. polyanthum essential oil were caryophyllene (40.79% rel.) and humulene (17.61% rel.); S. myrtifolium oil was dominated by 3- carene (20.05% rel.) and caryophyllene (16.45% rel.); while S. aqueum oil was mainly composed of 3- carene (23.58% rel.) and caryophyllene (18.96% rel.). Caryophyllene was identified as one of the principal compounds common to all three Syzygium species.

Tingkat Redam Suara Dan Ketahanan Papan Partikel Campuran Serbuk Kayu Sengon Dan Mesocarp Kelapa Sawit Terhadap Serangan Rayap Tanah: KUALITAS REDAM SUARA PAPAN PARTIKEL MESOCARP KELAPA SAWIT Indrayani, Yuliati Ferdiansyah, Adli Setyawati, Dina M., Iskandar A. komposit serat kelapa sawit Albizia chinensis rayap tanah tingkat redam suara The increase in palm oil production in Indonesia produces significant volumes of waste, including empty fruit bunches (EFB), shells, and fibers. This waste has the potential to be processed into particleboard, with the addition of sawdust to improve physical properties and termite resistance. An additional raw material is Sengon wood (Falcataria moluccana (Miq.)), which was chosen due to its economic value and fast-growing nature. The purpose of this study was to determine its physical properties, resistance to subterranean termite attacks, and sound attenuation level. Particleboard was made from a mixture of oil palm mesocarp fiber and Sengon wood particles using urea formaldehyde (UF) adhesive with a concentration of 18%. The raw material combinations of oil palm mesocarp fiber and Sengon wood particles were 0:100, 25:75, 50:50, 75:25, and 100:0. Hot pressing was carried out at a pressure of 25 kg/cm² and a temperature of 130 °C for 10 minutes. The results of the study showed that the physical properties of the material ranged from 0.37 to 0.39 g/cm, water content from 7.27% to 9.45%, thickness expansion from 5.94% to 11.71%, and water absorption from 96.53% to 149.79%. The resistance of the board to subterranean termite attacks, achieved with a combination of oil palm mesocarp and sengon powder 75:25%, resulted in the highest termite mortality. In comparison, the combination of oil palm mesocarp and sengon wood powder (100:0%) experienced the highest weight loss. The best sound attenuation level was achieved with a combination of oil palm mesocarp and sengon wood powder 0:100%.

However, due to the lack of basic knowledge about the properties of bamboo culms, only a few species are commonly utililized. This study aims to investigate the longitudinal variation of physical and mechanical properties of Dendrocalamus asper and Gigantochloa apus that grow naturally on Lombok Island. Sampling was carried out by selecting 10 bamboo culms, aged 3-4 years old, from different clumps at each location. The tests conducted include moisture content, basic density, tangential and radial shrinkage, modulus of elasticity (MOE), and modulus of rupture (MOR). Statistical analysis was performed using R software, incorporating linear and non-linear mixed-effects models to evaluate longitudinal variations and the influence of individual and location on the distribution of bamboo properties. The results showed that the values for green moisture content, basic density, tangential and radial shrinkage at 1% moisture content change, MOE, and MOR for G. apus were 99.97%, 0.60 g/cm³, 0.29%, 0.35%, 8.27 GPa, and 108.80 MPa, respectively. Meanwhile, the values for D. apser were 108.13%, 0.58 g/cm³, 0.34%, 0.42%, 9.71 GPa, and 102.47 MPa, respectively. The longitudinal variation of moisture content in G. apus followed a linear pattern, while a logarithmic equation best described the variation in moisture content of D. asper, basic density, MOE, and MOR for both bamboo species. Additionally, the longitudinal variation in tangential and radial shrinkage for both species remained constant, following a linear equation with a y-intercept.

KARAKTERISTIK PRODUK DARI ESTERIFIKASI DENGAN BANTUAN GELOMBANG ULTRASONIK TERHADAP MINYAK BIJI KAPUK TEROZONASI Haryono Engela Evy Ernawati Atiek Rostika Noviyanti Biodiesel esterification kapok seed oil ozonation ultrasonic waves The kapok seed oil is non-edible oil so it is very profitable as a raw material for making biodiesel. However, the kapok seedoil is dominated by long chain and unsaturated fatty acids. These types of fatty acids tend to reduce the quality of biodiesel, namelythe low cetane number and trigger polymerization reactions during combustion. Ozonation could be applied to shorten the carbonchain and the number of double bonds in fatty acids from kapok seed oil. This research aims to study the effect of time of ozonationat preparation stage of kapok seed oil on biodiesel characteristics of esterification stage with the assistance of ultrasonic waves. Theozonation time was varied for 60, 90, and 120 minutes. The results showed that the longer the time of ozonation the kapok seedoil produced with the increased acid number. The greater acid number of the kapok seed oil was verified by the fatty acid compositionof Gas Chromatography-Mass Spectroscopy analysis, showed that the fatty acid structure of the kapok seed oil became simpler.The esterification for 120 minutes to ozonated kapok seed oil which has been ozonized produces oil phase with an acid number of10.6 mg KOH/g, a saponification number of 112 mg KOH/g, and a density of 903 kg/m3.

Bamboo culm’s cross-sectional geometrics vary and may be similar to conic such as acircle, ellipse, or egg-shape ring. The best-fit conic section, which is the most similar to the actual geometric shape of the bambooculm’s cross-section, should be considered. This study formulates mathematical equations for calculating the bamboo culm’s crosssectional properties (including the area, the first moment of area, the centroid, and the moment of inertia), which are fitted by acircle, ellipse, and egg-shaped ring. The thickness, diameter, major axis, and minor axis of four bamboo species (i.e., Gigantochloaapus, Bambusa vulgaris, Gigantochloa pseudoarundinacea, and Gigantochloa robusta) were measured, and thosevalues were substituted into the equations to produce the range of cross-sectional properties of each species.

BIOMASSA SEBAGAI MATERIAL ELEKTRODA SUPERKAPASITOR Nur Adi Saputra Wasrin Syafii Gustan Pari Deded Sarip Nawawi Akhiruddin Maddu Activated carbon pore size supercapacitor electrical storage renewable Electrical storage and distribution devices become important in next generation to help integrate more renewable energy intothe electricity grid. Supercapacitor technology is considered the most promising alternative to Li-ion batteries, which have limitedLithium material. However, the low energy density is a weakness of supercapacitors, even though they have a high-power density.Activated carbon-based supercapacitor electrodes have ideal potential for development. The inherent attributes of activated carbon,pore properties, and functional groups, are responsible for improving the performance of supercapacitors. The main challenge for theresearchers is the pore size distribution, micro (<2nm), meso (2–50 nm), and macro (>50 nm), which varied in activated carbon.Micro pores have an impact on increasing the value of specific capacitance values which will encourage an increase in energy density.Meso pores have an impact on the overall accessibility of the electrode surface by electrolyte ions. Future studies will emphasize oncarbonization and activated carbon activation techniques to improve the surface quality of activated carbon.

HUBUNGAN ANTARA TITIK DIDIH DENGAN PERSENTASE MASSA DARI BEBERAPA LARUTAN MADU ALAMI DAN MADU KOMERSIAL Dede Suhendar Afifah Tasdiq Asep Supriadin Yusuf Rohmatulloh Natural honey commercial honey honey authenticity colligative properties boiling point The traditional society's need for natural honey cannot easily be met with the many alternatives to commercial honey today,but the consistency of traditional methods in determining the authenticity of natural honey has not been scientifically confirmed. Thissimple research aims to study the relationship between the boiling point and mass percentage of some dilute natural honey based onthe basic idea of the colligative properties of the solution and its comparison with some commercial honey samples. Each honeysample (six samples of natural honey and six samples of commercial honey) was diluted with distilled water in various weightpercentages of 2.5–15.0% (w/w), then the boiling points were determined in ambient temperature and pressure. By using polynomialregression of degree 3, it was found that all-natural honey solutions had a pattern of increasing boiling point with increasing weightpercentage, with different curvature patterns approaching linear (R3Lin), logarithmic (R3Log), exponential (R3Exp), and sigmoid(R3Sig) like patterns. The results of the comparison with six commercial honey solutions, there are only two samples that have anincreasing regularity pattern, the rest are like fluctuates and/or has no relationship. Based on these results, the natural honeysolution still has a close consistency with the colligative properties of the concentrated solutions so that it can be recommended as anew method in determining the authenticity of honey that has not undergone further processing, remains simple, easy, and inexpensivefor testing.

KARAKTERISTIK BALOK BAMBU LAMINA SUSUN TEGAK DARI BILAH BAMBU ANDONG (Gigantochloa pseudoarundinacea (Steud.) Widjaja) I.M. Sulastiningsih Adi Santoso Krisdianto Laminated bamboo beam vertically glued strips andong manii sengon isocyanate The objective of the study was to determine the effect of various layer compositions on the properties of 3-layer vertically glued laminated bamboo beam (LBB). Bamboo strips for LBB fabrication were prepared from mature culms (± 4 years old) of andong bamboo (Gigantochloa pseudoarundinacea (Steud.) Widjaja) collected from private gardens in West Java. The strips were pre-treated by soaking them in 7% boron solution for four hours. Three-layer LBBs were manufactured with six different layer compositions, including bamboo combination with wood planks of manii (Maesopsis eminii Engl.) or sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) as the core layer. The LBB was manufactured using Water Based Polymer-Isocyanate (WBPI) adhesive. The glue spread and cold pressing time applied were 250 g/m and one hour, respectively. Results showed that the average density, moisture content, thickness swelling, and width expansion of LBB were 0.65 g/cm ; 11.1%; 2.09%; and 1.99%, respectively. No delamination occurred in all samples using WBPI adhesive, which indicates high bonding quality. The average bonding strength and percentage bamboo failure (dry test) of LBB were 61.6 kg/cm and 90%, respectively. The physical and mechanical properties of LBB were significantly affected by the layer composition. The presence of wood laminates as the core layer of LBB and the cross wide orientation of the core layer decreased mechanical properties of LBB. On the contrary, the presence of cross-layer in LBB structure increased dimensional stability of the produced LBB.Three-layer thick laminated bamboo beam made of vertically glued andong bamboo strips with various constituted layer composition and all constitued layers laminated together in parallel grain direction had strength values comparable to those of class II of solid wood strength, eventhough the core layer was made of sengon or manii planks.

POTENSI SIMPANAN KARBON DAN EMISI CO2 AKIBAT PENEBANGAN DI HUTAN ALAM PAPUA Yuniawati Dulsalam Sarah Andini Carbon storage CO2 emission decrease felling Forests as a place for carbon sequestration will be a source of emissions if there are no more photosynthetic plants to store carbondioxide (CO2) gas. CO2 gases that spreads in atmosphere can affect global climate change. Uncontrolled timber harvesting innatural forests has a negative impact on the potential for carbon absorption and CO2 emissions. This study aimed to analyze thepotential for carbon storage and emission due to felling in natural forests. The research method was carried out destructively andnon-destructively using data on potential stands before felling and the potential for trees to be felled on three logging compartmentsby making nine sample observation plots (PCP) in three selected felling plots within the natural forest concession area, namely plotsnumbered CC 47, K47, and L 47. Each PCP was a rectangular plot measuring 2 ha (200 x 100 m2). The results showed thatthe natural forest stand structure in the study location formed an inverted J letter, where the stands with a diameter class of 60 cmand above had a lower stand volume than other diameter classes. Carbon storage in the stand before felling was 21.07 ton C/ha.The potential for carbon storage decreased when 144 trees were felled, resulting the reduction was 18.49 ton C/ha, causing apotential carbon emission of 67.86 tons CO2-eq. After felling, the potential for carbon storage was decreased or remained by 2.57ton C/ha so that the potential for emission in the post-felling area was 9.43 tons CO2-eq.

Testing of rattan laminated board products includes bonding strength and formaldehyde emissions, and also the bonding strength value of samples from the National Rattan Innovation Center (PIRNas) as a comparison. Results show that bonding strength and formaldehyde emissions of the rattan laminated board was influenced by interaction type of tannin-formaldehyde, pressing temperature, and glue spread. The best quality adhesive performance of rattan boards was obtained on the use of tannin-formaldehyde mangium resin with formaldehyde emissions with a glue spread of 200 g/m2 surfaces and 100oC pressing temperature, with formaldehyde emmision within the safe limits. Approximately 28% of the experimental rattan laminated boards possessed bonding strength which exceeds bonding strength value of the PIRNas board, which used synthetic resin based on the imported phenolic adhesive.

SINTESIS, KARAKTERISASI DAN APLIKASI BIO-IMPREGNAN DARI KULIT BATANG SAWIT Jamaludin Malik Adi Santoso Jamal Balfas Synthesis characterization application bio-impregnatnt oil-palm bark The formulation of phenolic compounds extracted from biomass not only produces adhesives but can also be used as bioimpregnant. In this study, the synthesis was carried out by copolymerization of resorcinol (R) and formaldehyde (F) into the oilpalm bark extract (S) to produce SRF resin fluid. A complete characterization was carried out using FTIR, Py-GCMS, XRDand DTA. In addition, F emission was also undertaken to ensure its safety for health and the environment. The application ofbio-impregnant was done on samples of the hard (edge) and soft (middle) parts of the oil palm trunk. The results show that the oilpalm bark extract contains polyphenol components that have a strong affinity for resorcinol and formaldehyde in alkaline catalyst(NaOH 40%), so that it can form a copolymer that can be used as an impregnant. The application of the bio-impregnant canimprove the quality of the oil palm trunk in both parts from class V to class III of wood-strength classification with an increase indensity (>100%), hardness (4 times), thickness swelling in both cold and boiling water meets the requirements (<25%), as wellas formaldehyde emission that meets the standard SNI 03-2105-2006.

PENGARUH BERAT LABUR DAN JENIS KAYU TERHADAP SIFAT FISIKA DAN MEKANIKA PAPAN LAMINASI Febriana Tri Wulandari Radjali Amin I Gde Adi Suryawan Wangiyana Laminated board physical and mechanical properties glue spread type of wood The world's demand for wood is increasing while the amount of solid wood production is decreasing with the depletion of forestsdue to illegal logging and conversion of forest functions as plantation land. To overcome these problems, it is necessary to do theefficiency of wood raw materials so that the use of solid wood can be reduced. One of the efficient ways to use wood raw materials isto utilize optimized wood industrial waste by combining one or more types of wood which are glued together into a single unit,commonly called a laminated board. In this study, we will look at the effect of different types of wood and the weight of the gluespread on the resulting laminated board. Advantages Laminate board can produce a board size that is wide and long as neededbecause the joints are made as long as needed. In the manufacture laminated boards are made with the type of wood, namely jatiputih (Gmelina arborea. Roxb), bajur (Pterospermum javanicum), sengon (Paraserianthes falcataria) and mixtures(jati putih, bajur and sengon) and the glue spread factor is 150 g and 200 g. Then the physical and mechanical properties weretested. The test results showed that the wood type had a significant effect on all physical and mechanical properties except for thethickness shrinkage and MoE tests. The interaction of the lamination glue spread factor and the wood type factor did not significantlyaffect all physical and mechanical properties of mixed wood waste laminated boards. Based on the test results, laminated board isclassified as strong class III which can be used as a lightweight construction material indoors.

PENGARUH PRAPERLAKUAN BAHAN BAKU TERHADAP KUALITAS PAPAN LAMINA ROTAN Adi Santoso Gustan Pari Krisdianto Karnita Yuniarti Jasni Heru Wibisono Rattan Batang (Calamus zolingerii) pretreatment tannin mangium adhesives rattan laminated board Rattan has the potential to be developed into composite products with gluing technology into laminated rattan. However, as araw material, rattan has a weakness, namely that it contains chemical components that inhibit the adhesive bond with the chemicalmolecules of rattan. In an effort to overcome this, a technique for making composite rattan was carried out in order to obtain dataon the effect of pretreatment on rattan as a raw material. Rattan as a raw material is first dried by microwave, hydrothermalevaporation and conventional methods in order to reduce the levels of adhesive chemical components contained in rattan. This paperpresents the results of research on the technology of making laminated rattan from the Batang (Calamus zolingerii) large diameter(>20 mm) with mangium tannin adhesive. The results showed that the pre-treatment of rattan as a raw material in the form ofdrying by means of oven, steam, frying, hydrothermal, and microwave, each produced a different effect on the chemical componentscontained and the degree of crystallinity. The best rattan laminate board was obtained from rattan which was pretreated using a 1kW microwave oven (input) with a maximum energy strength of 50%.

PENGARUH ZAT EKSTRAKTIF KAYU GAMAL (Gliricidia sepium Jacq.) TERHADAP NILAI KALOR Rahmi Mauladdini Wasrin Syafii Deded Sarip Nawawi Calorific value different polarities Gliricidia sepium Jacq. maceration n-hexane soluble compounds The development of gamal wood (Gliricidia sepium Jacq.) aims to meet the needs of biomass energy in rural areas. Manystudies on extractives of gamal wood have been carried out, but there is very little information about the effect of extractives on thecalorific value. The effect of extractives on the calorific value can be determined by analyzing extractives compounds contained in thewood. This study aimed to determine the extractives compounds that affect the wood calorific value. The sawdust of gamal bark andwood was extracted by successively maceration by using solvents with different polarities. The free-extractives sawdust was thenmeasured for its calorific value. To ascertain the effect of extractives on the calorific value, the extract of the gamal bark and woodwas added to the oil palm sawdust, then the increase in calorific value was measured. The results showed that the extractives ingamal bark and wood affect the change of calorific value. The removal of extractives by using different solvents caused a differentdecrease in calorific value. The highest decrease in calorific value (4.03%) was obtained by non-polar (n-hexane) soluble extractiveof the gamal bark. The addition of gamal wood extracts to oil palm sawdust also causes an increase in the calorific value.Phytochemical and LC-MS/MS analysis of n-hexane soluble extractives from gamal bark detected groups of terpene compounds,amides alkaloids, flavonoids, coumarins, and benzopyrans. Based on the results of this study, the n-hexane soluble compounds wassuspected to have the most influence on the calorific value.

PERUBAHAN WARNA DAN LAPISAN FINISHING LIMA JENIS KAYU AKIBAT PENCUACAAN Krisdianto Esti Rini Satiti Achmad Supriadi Outdoor Exposure Five Wood Species Color CIELab Coating Coverages The increase use of wood products for outdoor arises from warmth color and amenity properties of wood. However, wood is naturally degraded in term of color changes and finishing layer percentage after outdoor exposure. This paper presents wood color change and finishing layer durabillity after one year outdoor exposure. Five lesser known wood species from Riau were coated transparently using acrylic, enamel, polyurethane, ultran lasur ultra violet (UV), and ultran politur P-03 UV prior to outdoor exposure. Wood color differences were assessed according to CIELab system and coating film coverages were digitally analyzed by ImageJ software. The result showed that natural wood color turned into greyish pale after one year outdoor exposure. Color changes are relatively high in the first month then moderate and little changes every month there of. Finished layer wood samples were more resistant to weathering than unfinished surfaces. Finishing material of enamel (ET), lasur (LSR), and P03 (PP) experienced better coverage than acrylic and polyurethane finish. Finishing layer is gradually degraded, then re-finishing is necessary for optimal outdoor protection. Relationships between finishing coverage and color change showed medium correlation, where the greater finishing coverage, the greater the color changes.

VARIASI KEASAMAN DAN KAPASITAS PENYANGGA KAYU TAMPUI BERAS ( Baccaurea macrocarpa (Miq.) Muell.Arg.) dan MANGGIS HUTAN ( Garcinia cornea Miq.) Krisdianto Acidity Buffer Capacity Tampui Beras Manggis Hutan Wood acidity signifies an important factor that inflicts impact on metal corrosion and gives effect on adhesive bonding quality. Wood acidity varies not only between species, but also at different parts in the same tree. This paper studies the wood pH and buffering capacity at various positions in the same tree of two potential species from Rian. Those wood species are locally known as tampui beras (Baccaurea macrocarpa (Miq.) Muell. Arg.) and manggis butan (Garcinia cornca Miq.). The pH was determined using pH meter on the liquid of bot-water-extracted sawdust of the corresponding wood, while buffering capacity was measured by acid and base titration. The result shows that in average, acidity of tampui beras wood (5.2) is stronger than that of manggis hutan (6.3). Both wood species are classified as acid wood with pH less than 7. With respect to the tree height, sample taken from bottom part has the lowest pH value, while based on lateral position at the stem, progressing from the bark in depth to the pith the sapwood is higher in pH value than the beartwood and transition area. In every wood sample tested, acid buffer capacity is higher than base capacity.

PEMANFAATAN ASAP CAIR KAYU PINUS (Jungh. & de Vriese) SEBAGAI KOAGULAN Pinus merkusii GETAH KARET Santiyo Wibowo Gustan Pari R. Esa Pangersa Gusti Smoke liquid coagulant latex quality physico-chemical properties Smoke liquid is a liquid obtained from smoke condensation during charcoal firing process. The main content of the smoke liquid is acetic acid, hence, can be used as an alternative latex coagulant. Acid in vinegar can reduce the pH of latex and cause the latex to coagulate rapidly. This paper determines effectiveness of using smoke liquid as a latex coagulant and characteristics of the treated latex. The smoke liquid in this study was derived from pine wood. The smoke liquid solutions consisted of the crude smoke liquid and the diluted solution in various concentrations of 5, 10, 15 and 20%. The smoke liquid solution was then each poured into a container of latex. Testing was undergone by observing latex coagulating time, coagulate condition, texture, color, odor and homogenity. The most effective smoke liquid which produced the best latex based on its performances was then taken for further testing of physico-chemical properties which included dry rubber content, plasticity retention index (PRI), initial plasticity (Po), final plasticity (Pa), dirt content, ash content, volatile matter content (Vm), and nitrogen content. Results were then compared with the conventional use of formic acid as a control coagulant. The result showed that the crude and distillate smoke liquid solutions with concentration of 10% produced the best coagulantperformances than the other solutions. Rubber latex treated with the crude smoke liquid produced the best physico-chemical properties and could meet requirements of the Indonesian National Standard (SNI) for Rubber Quality.

The application of glued-laminated timber (glulam) could overcome theseissues and increase its utilization. This paper reviews the utilization of wood from plantation forest for glulam. Currently, woodfrom plantations forest studied in glulam research were jabon (Anthocephalus cadamba), rubber-wood (Hevea brasiliensis),mahogany (Swietenia sp.), mangium (Acacia mangium), manii (Maesopsis eminii), mindi (Melia azedarach), pine(Pinus merkusii), sengon (Falcataria moluccana), and sungkai (Peronema canescens). Kempas wood (Koompassiamalaccensis) and merbau (Intsia sp.) from natural forests were used as a layer combination of the glulam. The adhesives usedfor manufacturing glulam were tannin-based adhesives from mangium, mahogany, and merbau, as well as synthetic adhesives,namely isocyanate and phenol resorcinol formaldehyde (PRF). The results shows that glulam bonded with tannin-based adhesivehas physical-mechanical properties comparable with those of solid wood and glulam adhered with PRF adhesive. The physicalmechanical properties of glulam glued with isocyanate were similar with its solid wood. However, the shear strength of glulam waslower than solid wood. There was no delamination occurred in both cold and boiling water delamination tests. Thus, it fulfilledJAS 1152- 2007. The polystyrene impregnation applied in sengon and mindi glulams manufacturing resulted in a few effect ofcolor change, comparable shear strength to its solid wood, and increases its resistance to subterranean termites (Coptotermescurvignathus Holmgren) attack.

HUBUNGAN ANTARA KADAR EKSTRAKTIF DENGAN SIFAT WARNA PADA KAYU TERAS JATI Ganis Lukmandaru Tectona grandis extractives colour properties CIE-Lab heartwood Beside for its high natural durability and resistancy of weather properties, teak (Tectona grandis) wood is also valued for its beautiful grain and colour. Theoretically, wood colour is highly affected by extractive content, particularly in the heartwood. Identification of correlation between wood colour and extractive content was determined through wood colour and extractive measurements on the outer part of heartwood zone. The wood samples were collected from two locations of Perum Perhutani forest plantations, i.e. KPH Randublatung (35 trees, age class III-IV) and KPH Purwakarta (32 trees, age class VI). Samples were cut from bottom part of the trees and then ground into powder measuring of 40-60 mesh. The wood colour properties(CIE-L*a*b, CIE-L*C*h, CIE-X*Y*Z, Munsell Colour Chart and ISO Brightness) were then measured. Solubility of the teak wood extractives were determined by extracting the powder in ethanol-benzene and hot water respectively. Results showed that the range of colour properties were L*= 40-62; a* = 3-11; b* = 19-31; C* = 20-31; h = 70-82; X= 10-25; Y= 8-23; Z=4-13; H=5-8; V =3-8; C =3-6; and W (ISO Brightness) = 4-12. Different sample location resulted in different trends of correlation between colour properties and extractive contents. No significant correlation was found between extractive solubles in hot water and colour parameters. In general, the best correlations were encountered between brightness parameters from CIE-L*a*b* or ISO with ethanolbenzene extractive contents (r=- 0.54 or 0.50, respectively).

AKTIFITAS ANTIOKSIDAN DAN ANTIKOAGULASI RESIN JERNANG Totok K. Waluyo Gunawan Pasaribu Rattan Fruit Dragon's Blood Organic Solvent Phytochemical Antioxidant Anticoagulant Dragon's blood is essentially a red-colored resin secreted by the fruits of rattan species. The dragon's blood originated from Indonesia which becomes widespread in international market is indigenous from Daemonorops spp. The dragon's blood has been popularly used as traditional medicines. To confirm such dragon's blood efficacy, an assesment was already conducted regarding the phytochemical screening, antioxidant activity, and anticoagulant activity indicatively afforded by the dragon's blood resin produced by three rattan species, ie. Daemonorops longipes Mart, Daemonorops draco BL, and Daemonorops melanochaetes BL. Phytochemical screening aimed to identify the kinds of chemical compounds inside the dragon's blood resin; antiæcidant tests used DPPH (2,2-diphenyl-1-picrylhydrazyl); and anticoagulation tests proceed in-vitro using rabbit blood. Results revealed that the dragon's blood from those three species, exctracted using polar (methanol) and semi-polar (ethyl acetate) solvents, contained chemical compounds which are already renowed for medicinal efficacy and potent antinccidant, e.g. flavonoids, triterpenoids, and tannin. The greatest antioccidant potency was imparted by dragon's blood from Daemonorops longipes Mart, as indicated by its lowest IC value (71.89U+3,89 mgl.). The ethyl acetate dragon's blood extract, rather than promoting anticoagulat action on the rabbit-blood, in fact induced the blood coagulation, whereby the extract from Daemonorops longipes Mart performed the most effectively (shortest in coagulation time).

IMPROVEMENT ON SEVERAL PHYSICAL AND MECHANICAL PROPERTIES OF JATI UTAMA NUSANTARA WOOD BY THERMAL COMPRESSION TREATMENT Efrida Basri Saefudin Rapid growth teak thermal compression physical and mechanical properties 185°C Jati Utama Nusantara (JUN) is one type of growing regime of fast grown teak (Tectona grandis Linn. F) derivedfrom Jati Plus Perhutani (JPP). JUN trees have fewer branches and a more cylindrical-shaped trunk, as well asexhibit rapid growth compared to the teak cultivated from seed (conventional); accordingly, they can beharvested in a shorter time. Despite its fast growth, some studies showed that the wood had not met the SNI01-0608 standard as raw material for furniture. The research aimed to improve several physical and mechanicalproperties of young JUN wood through thermal compression treatment. The test sample for 5-year-old JUNwood was prepared with a size of 2.5 cm (thickness/radial) by 10 cm (width/tangential) by 30 cm(length/longitudinal), then compressed using a 25 kg/cm2-pressure for 40 minutes in three temperaturetreatments of 170°C, 180°C, and 190°C. Testing of wood mechanical and physical properties referred to ASTMD143. The wood crystallinity was observed using an X-Ray Diffractometer (XRD), and the wood surface wasobserved visually. Wood cell structure as supporting data was observed using a stereo-capable microscope(Zeiss). The results revealed that the thermal compression could improve the physical and mechanicalproperties of the densified JUN samples compared to the nonthermally compressed samples. Based on datasimulation, the wood samples' best physical and mechanical properties occurred at approximately 185°C's heatpress.

KEMAMPUAN SEPULUH STRAIN JAMUR MELAPUKKAN EMPAT JENIS KAYU ASAL MANOKWARI Djarwanto Sihati Suprapti Freddy Jontara Hutapea Wood Decaying Fungi Strains Kolle Flask Method Manokwari Resistant Capability of decaying-fungi varies according to their strains. This paper studies the decaying capability of ten fungi strains against four wood species from Manokwari. The wood samples have been exposed to the ten fungus strains using Kolle flask method as mentioned in SNI 7207: 2014. Scrutiny results revealed that two of ten fungus strains were categorized as low decaying capability, which comprised of Chaetomium globosum and Lentinus lepideus. Meanwhile, four strains were classified as moderate decaying capability which were Schizophyllum commune, Trametes sp. HHBI-379, Trametes sp. HHBI-332, and Phlebia brevispora. The remaining four fungus strains were regarded as high decaying capability, namely Polyporus arcularius, Polyporus sp., Pycnoporus sanguineus, and Tyromyces palustris. The highest weight loss of wood occurred in the sapwood of Rhus taitensis exposed to Polyporus sp. Meanwhile, the lowest loss was obtained on the heartwood of Haplolobus sp. caused by L. lepideus exposure. Three wood species comprising Tetrameles nudiflora, Rhus taitensis, and Pimeleodendron amboinicum belonged to non-resistant wood (class IV), while Haplolobus sp. was grouped into resistant wood (Class II).

KINERJA MESIN PENGERING MIKRO BERTENAGA KOMBINASI SURYA DAN LISTRIK DALAM PENGERINGAN KAYU JATI Galit Gatut Prakosa Ramli Ramadhan Drying micro drying machine teak solar energy modification Indonesia is one of the exporting countries for wood crafts to 193 countries, but in the process, it often suffers losses due toproduct returns by the buyer due to cracked defects when the goods arrive at the ordering country. One of the efforts to improve thequality of wood crafts is to dry the wood according to the destination country so that the dimensions and humidity are relativelystable. The industrial-scale wood drying process requires a high investment, so developing a small-scale dryer for artisans is necessary.This study aims to design and test the performance of a simple wood dryer with a capacity of 1.5 m³ at an affordable cost, easy tooperate and use by the public. The test samples used were stems and branches of teak (Tectona grandis L.f.). The heater used isa combination of solar heat and electricity, namely the heat of the sun is maintained and flowed into the wood drying chamberthrough a fan that sucks hot air from the combustion chamber into the drying chamber. Hot air is circulated to the inlet againcontinuously to be redistributed to the drying chamber. The test results show that the daily average temperature of solar heat receivedby the drying chamber is between 40−50°C, while the temperature for drying teak wood is between 45−70°C. From the evaluationthat has been done, the heating plate is less effective in heating the space, so it is necessary to replace it with a modification of theinstallation of the heating element on battery powered devices.

10.20886/jphh.2018.36.2.129-138 Jamal Balfas Efrida Basri Adi Santoso Finishing Organic Wood Filler Shellac Acrylic Polyvinyl Acetate The use of wood filler is vital in wood finishing. However, the most commercial wood fillers available in the market are made of chemical solvent-based resins, such as polyurethane and nitrocellulose. These products contain volatile organic compounds. This study examines performance of alternative and commercial wood fillers. The alternative wood fillers were made from the mixture of putty powder and organic resins, i.e. shellac, acrylic and polyvinyl acetate. The wood fillers were tested on tusam, jabon and rubber wood by assessing their physical, mechanical and chemical performances in comparison with the most commercial wood filler, i.e. nitrocellulose wood filler. Samples of three wood species were treated by spreading them with various wood filler solutions. Weight and dimensional changes due to treatment were determined in wet and dry sample conditions. Chemical and scratch resistance of the wood filler films were also tested to determine their chemical and mechanical performance. Color similarity of the wood filler treated samples and control were evaluated using the CIELab color system. The effect of treatment were varied according to wood species. Tusam samples possess greater weight and dimensional gains than those of jabon and rubber wood samples. All organic wood filler formula could effectively protect wood from water intrution, comparable to that of the commercial wood filler (WF). The organic wood fillers had higher scratch resistance, less chemical resistance, and better color appearance than the commercial WF.

PEMANFAATAN TEKNOLOGI KERTAS NANO KARBON SEBAGAI PEMBUNGKUS WORTEL Dian Anggraini Indrawan Novitri Hastuti, Lisna Efiyanti Gustan Pari Paper Bamboo Activated Charcoal Wrapping Carrot Nutrition Indonesia’s paper consumption, including food wrapping-paper, might steadily increase in the future. This could someday upset the capability of domestic wrapping-paper production due to dwindling potency of conventional fibers (e.g. natural-forest wood). Alternative fibers are abundantly available and it mostly remains unutilized, than it should be introduced in industry, such as bamboo. This study aims to optimize the utilization of alternative fiber sources through the manufacture of wrapping paper from bamboo fiber using carbon nano technology as a foodstuff protector/wrapping. Relevantly, manufacturing trial on papers with nano-technology capability for carrot wrapping was conducted from two bamboo species tali (Gigantochloa apus) and ampel (Bambusa vulgaris) separately. Initially, each species was pulped semi-chemically, and then added with nano-sized activated charcoal particles (20%, w/w). The mixture (bamboo pulp + activated charcoal) was formed into sheets with targeted basic-weight common for wrapping-paper (60 g/m2), and then used for carrot wrapping and the physical strength properties was tested. Result shows that charcoal could can lower carrot-weight loss, which indicates high effectivity in maintaining the carrot freshness and nutritions. Papers made from ampel-bamboo fibers were more prospective for such wrapping than those made from bamboo tali. The use of any experimented papers for carrot wrapping was still better than without wrapping, as they afforded more in securing carrots.

PENGGUNAAN Phanerochaete chrysosporium PADA PENGOLAHAN PULP BIO-SEMI-MEKANIS KAYU TERENTANG (Campnosperma auriculata Hook.f) Yeni Aprianis Denny Irawati Sri Nugroho Marsoem Incubation period Phanerochaete chrysosporium biopulping terentang Terentang wood (Campnosperma auriculata Hook.f) is relatively low in specific gravity (0.3), hence its utilization as pulp by chemi-mechanical is an alternative process. Energy consumption was reduced by applying lignin degrading fungi (Phanerochaete chrysosporium) as pretreatment in the chemi-mechanical process. This paper examines the effects of P. chrysosporium incubation periods into chemical components and energy refining consumption of terentang wood. Four percent of NaOH was used in the chemi-mechanical process, and incubation periods studied were 0 (control), 3, 4 and 5 weeks. Results showed that P. chrysosporium significantly affected the weight loss, chemical properties, and refining energy consumption of terentang wood pulping process. Wood chip weight loss was about 15.95-21.31% and alpha-cellulose raised up to 6.77%. Five weeks incubation time decreased lignin content up to 22.97% and saved the refining energy up to 22.7%.

ANALISIS KARAKTERISTIK FUNGSI ZEOLIT ALAM AKTIF SEBAGAI KATALIS SETELAH DIIMPREGNASI LOGAM NIKEL Rina Novia Yanti Erliza Hambali Gustan Pari Ani Suryani Catalyst nickel FTIR XRD ZAA/Ni natural zeolite Catalytic cracking is a conversion process by cutting the carbon chains of oil molecules into simple hydrocarbons. The process ofbreaking the hydrocarbon chain could be conducted by chemical means using a catalyst and hydrogen gas. The types of catalystscommonly used in the chemical industry are metals such as nickel (Ni), zinc (Zn), and cadmium (Cd). The metal can be used asa catalyst directly, but during the catalytic cracking process, the catalyst will thicken than it is imposible to re-use the catalyst.Therefore, the metal catalyst must be impregnated into a carrier material such as zeolite. The research is aiming for analyzing thecharacteristics of active natural zeolite catalyst with nickel-metal impregnation (ZAA/Ni), which consisted of surface area analysis,XRD, FTIR, and morphological analysis best catalyst. The zeolite used in this research is originated from Bayah Banten, whichhas been activated. The function of the catalyst can be improved by the presence of a carrier, namely nickel metal. The role of thecarrier is as a place for the active nucleus to spread, which can increase the effectiveness of the catalyst so that the catalyst can beused repeatedly. Results show the highest Si/Al ratio is 6.66, an intermediate catalyst with a Si/Al ratio = 2−10. The widestsurface area of the catalyst is at ZAA/Ni 3% of 974.44 m2/g; the crystallinity value the largest was 70.09%. Zeolite fromBayah Banten, impregnated with nickel-metal, can be used as a catalyst for upgrading bio-oil with a concentration of 3% ZAA/Niand 2% AA/Ni.

SIFAT PENGKARATAN LIMA JENIS KAYU ASAL CIAMIS TERHADAP BESI Djarwanto Metal Screw Tree Sample Wood Iron Corrosion Five wood species namely tangkalak (Litsea roxburghii Hassk.), cangkring (Erythrina fusca Lour.), kayu putih Melaleuca cajuputi Powell.), ki tanab (Zanthoxylen rhetsa DC.), and huru leneur (Sterculia cordata Blume), were evaluated based on their metal corrosion properties using jam-pot methods. Wood samples were extracted from two tree stands, divided radially into three groups, namely outer, middle and inner part of log. The results showed that iron corrosion was found in all wood species. The corrosion intensities were identified by the weight loss of the attached metal screws. Higher corrosion rates were found on samples of kayu putih. The highest weight loss of screw was found on kayu putih samples extracted from midle part (B part) of P-II tree, i.e. 2.76%. The lowest weight loss of screw was encountered on tangkalak wood samples extracted from inner part (C. part) of P-Il tree. The percentage of samples weight loss on tree-1 was lower (0.55%) than that on tree-11 i.e. 0.72%.

TEKNIK PENYADAPAN PINUS UNTUK PENINGKATAN PRODUKSI MELALUI STIMULAN HAYATI Sukadaryati Dulsalam Pine Biostimulants Enhanced Pine-sap Production Environment Effect The increased demand of pine resin both for domestic and overseas markets has necessitated efforts to enhance pine-sapproduction. The use of strong acid-based conventional stimulants has been long employed by Perum Perhutani, butquestions arise regarding the environment effect as well as growth survival of the tapped pine trees. Consequently, the use ofbiostimulant deserves thorough consideration, since not only will assure friendly-environmental effects but also securing thesustainability of the pine trees. An experiment was conducted to look into the effect of using biostimulants on theproduction of sap (exudates) from the tapped pine trees. Three tapping techniques were employed, i.e. mujitech, boring andkedukul. The biostimulant consisted of three kinds (lengkuas, kencur, and red onion), each with three concentration levels(50%, 75%, and 100%).It turned out different tapping techniques seemed not affecting the pine-sap production, nor did the effect of biostimulantconcentrations (50-100%). However, different kinds of biostimulants did so, whereby lengkuas afforded the sap-yieldincrease the highest (268%) compared to the control (without biostimulants), followed in order by kencur (206%) and redonion (180%). Use of the second and third caused no significant difference. Economically, the use ofbiostimulant at 50% concetration was effective enough. Further attempts are neseccary to find other alternativebiostimulants.

More efficientwood harvesting will reduce waste, which increases the standardization of exploitation factors (FE). Ironically, until now, theFE standard set by the Ministry of Environment and Forestry is still based on conventional wood harvesting methods, which is0.7. The sub-region of Central Kalimantan Province has a major role in contributing to production of natural forest logs, bothregionally on the island of Kalimantan by 61.5% and nationally by 29.7%. Still, the amount of wood harvesting waste is notknown with the standardized exploitation factor. This study aimed to obtain a standard number of exploitation factors fortimber harvesting activities in natural production forests in the sub-regional province of Central Kalimantan. The research wasconducted by initially selecting purposively logging companies with Sustainable Production Forest Management (PHPL)mandatory and voluntary certificates. The study was conducted in five of Forest Utilization Business License (PBPH) withPHPL mandatory certified and voluntary certificates. The results showed that the potential for logging waste due to stem divisionin felling site is an average of 0.919 m3/tree and the amount of logging waste due to testing and measurement at the TPn is onaverage 0.093 m3/tree. The FE score ranged from 0.80-0.85 with an average of 0.82. Factors that influenced the FE coefficientinclude the skill of the logger and management policy of PBPH and the diameter of the tree felled.

Agr durability preservation infused bandage Currently, the availability of red meranti, kulim and mersawa wood is commonly used as raw material for “jalur” constructionin Kuansing Regency, Riau Province, are increasingly scarce, while the need is getting higher. Accordingly, it is necessary to choosealternative wood types that have similar strength and durable properties compatible with red meranti, kulim and mersawa wood tomeet specifications for the “jalur” construction. This paper studies the effectiveness of preservative treatment by infusion techniqueand bandage use against dry wood termite. Balam (Macaranga conifera Muell. Agr.) was chosen as alternative wood for makingthe path because currently this wood is abundant but not much used for making pathways. The results of field observations indicatedry-wood termites attacke the path stored on land, so it is necessary to preserve the path so that they are not attacked by wooddestroying organisms, particularly the dry-wood termites. Preservation treatments on standing trees using complex boron compoundsby infusion and bandage techniques were examined to increase the durability class of balam wood. Testing of dry-wood termiteattack was carried out according to the SNI 7207-2014 method. The data were processed using a completely randomized factorialdesign. The analysis results showed that the preservation by infusion and bandage techniques was significantly different in terms ofweight reduction and mortality of termites. Observation on the degree of attack visually on the control and infusion technique was40 (hold) lower than the bandage technique 70 (moderate). The highest mortality in infusion technique was 90.67% compared tocontrol 86.08%, and the bandage was 61.75%. Preservation using the infusion technique showed a higher boron content comparedwith the bandage technique.

Wibisono Tool engineering bioethanol Nypa fruticans sap biofuels High consumption of fossil fuel causes energy crisis since its reserve is decreasing. This fact stimulates many studies to find out alternative energy as fossil fuels substitute. Bioethanol is considered as one of the most important source of alternative energy extracted fromplants.This research is aimed to provide tool engineeringrequired in producing bioetanol from Nypa fruticanssap. The engineering is consisted of two reactors. The first reactor can be used for pasteurization, sacarification and fermentation. The important second reactor is used as a distillation unit. The tool engineering has important advantage by using SSF (Simultaneous Sacarification and Fermentation) technique. By using this technique, processof pasteurization and fermentation can be carried out in onereactor. However the low levelof bioethanol flow rate becomes the weaknessof this tool . Theyield of Nypa fruticanssap was about 13.5% and the bioethanol contentof 70-94.5% with an averageof 84.8%. The yield of bioethanol distillation can be improved through the dehidration process. Bioethanol content can be increased from 94.5%to 98.5% by the dehidration process.

This paper studies the characteristics of mahogany tannins and effective formulation of alternative adhesives made frommahogany bark extracts of mixture tapioca flour and industrial flour as extender applied to composite or glued products. The barkof mahogany was cut to the size of 2 cm x 1 cm x 0.1 cm, extracted with hot water (70–80°C) with a ratio of 1:3 (w/w,material/water) for 3 hours with two repetitions. After extraction product was filtered, and the filtrate was copolymerized usingresorcinol and formaldehyde under alkaline and room temperature conditions to produce resin tannin resorcinol formaldehyde(TRF). The blend of tapioca flour and industrial flour (1:1, w/w) as an extender was used in the TRF application to manufacturecomposite products. The results showed that this mahogany bark liquid extract could be copolymerized to form a resin which thenapplied as a wood adhesive in a cold pressing process. The optimum adhesive formula was a mixture of 0.25 mol of resorcinol and1-mol formaldehyde, with a 15% extender, and a catalyst (NaOH 40%) of 4% of the total weight of the adhesive formulation.The characteristics of mahogany tannin adhesives resemble those of the exterior type phenolic group.

Use of alternative fibers which are abundantly available and still largely unutilized, i.e. nypha midribs and coconut coirs, bas been attemped for MDF (medium-density fiberboard), using urea-formaldebryde (UF) adhesive However, such study showed that MDV from each of the two fiber sources could not satisfy the JIS and ISO standards. In relevant, improvement trial on MDF properties was accomplished using both kinds of fibers.  Intially, those fiber stuffs had their basic properties examined, i.e. specific gravity, chemical composition, and fiber dimensions and their derived values. The MDF's fibrous pulping employed a bat semi-chemical soda process under atmospheric pressure at two alkali concentrations (8% and 12%). The resulting pulps were then added with additives, i.. 5% alum, 5% tannin formaldebryde (TF) adbesive either incorporated with activated charcoal (5%) or not; and then shaped into MDF mat using wet process, Physical-strength properties and formaldebryde emission of the resulted MDF wery examined.  Assessing those properties, nypa-midrib fibers were more prospective for MDF than coconut-coir fibers, Activated- charcoal addition lowered MDF's formaldehyde emistion and improved dimensional stability, but decreased its strengths. In properties, MDF, from nypa fibers 100% were significantly the closest in satisfying the standard (JIS and LSO). Yet, coconut-enir fibers could still be prospective for MDF by missing them (pulp form) with wypa-fiber pulp at the propertion (w/w): 25%+75% and 50%+50%. The MDF with TF adhesive afforded better properties than the previous experiment (UF), n. greater strengths, lowered emotion and satisfying more of the 115 and ISO standard.

PENYEMPURNAAN TEKNIK PENYADAPAN RESIN PINUS DENGAN METODE KUAKAN Ika Nugraha Darmastuti Gunawan Santosa Juang R. Matangaran Damage of tree quare method organic stimulant pine resin tapping the number and width of quare Overtapping of pine resin in terms of quare size which is too wide and deep and the use of anorganic stimulant may cause tree damage and increase the risk of tree to fall. Modification of tapping technique may reduce the damage of trees and increase the production of pine resin. The modification should consider several aspects of economical, ecological, social, and technical. The objectives of the research were to determine the width and number of quare on each tree, the appropriate type of organic stimulant, and also cost analysis of the modified tapping technique. The results showed that different type of tapping such as width and number of quare per tree significantly gave different resin production. However, different types of organic stimulant and its interaction with number and width of quare was not correlated significantly with resin production. Modification of tapping techniques and the use of organic stimulant had direct influences on the cost and profit.

Iskandar Achmad Supriadi Adhesive extender flour of avocado seeds damar plywood internal bonding SNI The addition of extender in the adhesive mixture may reduce the cost of gluing in the plywood manufacture. The extender addition should not reduce the plywood quality in term of internal bonding. This paper examines the use of avocado seeds flour as an extender in the manufacture of damar plywood (Agathis alba Foxw.). Based on the total mixture weight, the seeds flour was grouped into three concentrations of 10%, 20% and 30%. The main adhesive used was Urea Formaldehyde (UF) and parameters tested includes moisture content, density and internal bonding strength. Results show that the average of plywood moisture content, density and internal bonding strength were 7.46%, 0.48 g/cm , 11.77 kg/cm , respectively. The moisture content and bonding strength of damar plywood meets the Indonesian National Standard (SNI). The maximum bonding strength was achieved by plywood with an extender of 10% avocadoseed's flour. The variation of extender contents shows the pattern of the greater the extender content the the lower the internal bonding strength.

KETAHANAN 45 JENIS KAYU INDONESIA TERHADAP RAYAP KAYU KERING DAN RAYAP TANAH Mohammad Muslich Sri Rulliaty Resistance 45 Indonesian wood species dry-wood termites subterranean termites Natural durability of forty five wood species collected from several forest regions in Indonesia was tested against drywood termites (Cryptotermes cynocephalus Light.) and subterranean termites (Coptotermes curvignathus Holmgreen). Natural durability tests against dry-wood termites and subterranean termites were conducted based on Indonesian standard SNI 7207:2014. Results show that six wood species are classified as very durable wood (class I), eleven wood species are durable (class II), and 28 species belong to the low durability classes (class III, IV and V) against dry wood termites (C. cynocephalus Light.). Similar tests against substeranean termites (C. curvignathus Holmgreen) reveal that seven wood species are classified into highly resistant (durable class I), 14 wood species are resistant (durable class II), and the remaining 24 wood species belong to durability class of III, IV, and V. The testing results indicate that wood with high natural durability against dry wood termites is not necessarily resistant to subterranean termites and vice versa.

FAKTOR KONVERSI LIMBAH PEMANENAN KAYU HUTAN TANAMAN DAN RENDEMEN PENGOLAHAN SERPIH KAYU Soenarno Wesman Endom Conversion factor waste wood chips yield harvesting forest plantations Timber harvesting in forest plantations of PT Korintiga Hutani was undertaken using length limitation of 4.10 m and minimum diameter of 10 cm. These limitations have created numerous trunk wastes in the field. Harvesting efficiency improvement is being considered by converting the wastes into wood chips. However, the company has to pay a provision of forest resources to the government for each volumetric unit (m³) of the converting wood wastes. This paper examines conversion factors for estimating conversion values from staple meter (Sm) or weight (ton) into m³ of akasia (Acacia mangium), eukaliptus (Eucalyptus pellita) and waru (Hibiscus similis). Results show that conversion value of 1 Sm A. mangium wood waste is equal to 0.35 m³, or 1 ton of the same waste is equal to 1.98 m³; conversion value of 1 Sm E. Pellita is equal to 0.48 m³, or 1 ton of the waste is equal to 1.41 m³. Conversion value for 1 Sm H. similis is equal to 0.34 m³, or 1 ton of the waste is equal to 1.95 m³. Processing recovery of wood waste into chips is 94% for A. mangium and E. pellita while recovery of H. similis is 90%. Hence, conversion factor of wood chips in relation with the required waste is 1 Sm chips = 0.38 m³ wood waste or 1 ton chips = 2.09 m³ wood waste for A. mangium. Conversion factor for E. pellita is 1 Sm chips = 0.38 m³ wood waste or 1 ton chips = 1.51 m³ wood waste; conversion factor for H. similis is 1 Sm chips = 0.39 m³ wood waste or 1 ton chips = 2.16 m³ wood waste.

PENGGOLONGAN PERFORMANS 25 JENIS ROTAN INDONESIA BERDASARKAN KERAPATAN, KEKAKUAN, DAN KEKUATAN Abdurachman Jasni Density MOE MOR rattan utilization prospective Rattan signifies as one of non-wood forest products; and its role in Indonesia is essential as it provides approximately 80% of the world's rattan demand. Rattan finds numerous beneficial uses, such as ropes, weaving-items, mats, baskets, household utensils, handicraft goods, and furniture products. The utilization of rattans for such products are determined by among others their density (D), strength (MOR), and stiffness (MOE), whereby the greater those three values, then expectedly the better the rattan qualities as well as their corresponding rattan products. In South East Asia, including Indonesia, there are 2 outof 8 rattan genera that afford high economic values, namely Calamus and Daemonorops. In relevant, scrutiny on 25 Indonesia's rattan species has been conducted, and their possible classification based on density, MOR and MOE was examined. Those 25 species were dominated by Calamus spp. and Daemonorops spp. Scrutiny based on the entirely tested rattan properties (D, MOR and MOE) revealed that as many 16% of 25 rattan species could be grouped as class I(superior); 36% as class II (good), 32% as classIII (moderate) and 16% as class IV (poor). Further scrutiny also based on thoseoverall three rattan properties indicated that four species as the most prospectively utilized (from the highest rank) were Korthalsia rigida Bl, Calamus inops Becc.ex Heyne, and Calamus koordesianus Becc; meanwhile those as the least prospective similarly comprised Korthalsia zeppelii Burret, Plectocomiopsis geminiflora (Griff) Becc, and Calamus ornatus Blume dan Daemonorops malanocaetes BL.

PEMBUATAN PULP UNTUK KERTAS BUNGKUS DARI BAHAN SERAT ALTERNATIF Dian Anggraini Indrawan Lisna Efiyanti Rossi Margareth Tampubolon Han Roliadi Wrapping paper conventional fibrous stuffs alternative fibers additives sludge Indonesia's paper consumption, including wrapping paper, might steadily increase in the future and create challenge for domestic wrapping-paper production due to the dwindling potency of conventional fibrous stuffs (e.g. natural-forest woods). Alternative ligno-cellulosic fibers should be introduced, such as pioneer-tree woods potential for plantation-forest (PF), e.g. jabon and terentang; sengon PF's logging wastes; pulp/ paper mill's sludge; and pineapple-leaf fibers. In relevant, trial on pulp manufacture for wrapping paper was conducted using those alternatives. Initially, each alternative-fiber was examined for their basic properties (i.e. specific gravity, chemical composition, and fiber dimensions/ their derived values). The fibrous pulping employed a hot alk ali semi-chemical process (except sludge). The pulp-sheet with 60 g/ m basis-weight target was 2 formed from the mixture of jabon-wood pulp, terentang-wood pulp, sengon-wood pulp, sludge, and pineapple-leaf pulp (w/ w) in particular proportions; then to each proportion were added additives (alum 2%, clay 5%, wax emulsion 3%, tapioca starch 4%, and rosin soap 3%); and on the resulting pulp-sheets were tested their physical, strength, and optical properties. Results revealed that the proportion regarded as the most prospective for wrapping paper comprised terentang wood pulp (20%), jabon-wood pulp (20%), sengon-wood pulp (40%), and pineapple-leaf pulp (20%). The tolerable proportion for incorporating sludge should comprise sludge (20%), terentang-wood pulp (20%), jabon-wood pulp (20%), sengon-wood pulp (20%), and pineapple-leaf pulp (20%). The presence of harmful/ toxic heavy metals in the sludge which have been strongly indicated should thoroughly be accounted; and hence further experiment on their removal prior to the sludge use for wrapping paper deserves carrying out.

However,particleboards made from sengon has seome inferior physical and mechanical properties, which did not meet the Japanesestandard (JIS A 5908: 2003). The aim of this research is to improve the physical and mechanical properties ofsengon particleboard using sorghum bagasse in various raw material composition using citric acid adhesives. Citric acidwas used as a binding agent with 20% adhesive content based on the weight of the air-dried particle. Compositionof fiber mixtures between sengon and bagasse sorghum were set in 100:0, 75:25, 50:50, and 25:75 wt.%. Thetargetted density of particleboard was set at 0.80 g/cm3. The hot-pressing conditions of particleboard manufacturingwere 200°C for 10 min. The physical and mechanical properties of the particleboards were evaluated according toJIS A 5908: 2003 standard. The results showed that the density, moisture content, thickness swelling, modulus ofelasticity, modulus of rupture and internal bond met the requirements of the JIS A 5908-2003 standard. Thus, theadditional of bagasse sorghum becomes an alternative way to enhance the physical and mechanical properties of sengonparticleboard. The addition 75% bagasse sorghum had better moisture content, water absorption, thickness swelling,modulus of elasticity, and modulus of rupture of particleboard.

PENGARUH KADAR PEREKAT TERHADAP SIFAT PAPAN PARTIKEL AMPAS TEBU M. I. Iskandar Achmad Supriadi Particlelmard Bagate UF Adhesive Physical and Mechanical Properties Standards Particleboards as one kind of the reconstituted wood products in their manufacture still rely on the Sonventional wood material from natural forest, which in potency becomes limited and scarce. Consequently, use of alternative woods or other ligno-cellulosic fibrous stuffs deserves thorough consideration, with their potency abundant and mostly still unutilized, such at bagasse (sugar-cane fibers) waste from sugar factories. In relevant, a research on particle board manufacture avus conducted using bagasse particles bonded together with urta-formaldehyde (UF) adhesive. This research aimed to look into the effect of UF content (i.e. 6%, 8%, and 10% based on the dry weight of the particles) on the physical-mechanical properties of the resulting particleboard. Results revealed that increasing the UF content brought about a significant decrease in the thickness swelling and water absorption of the board; and increases in MOR, MOE, and crew-withdrawal strength, but inflicted so significant changes on the moisture content, density, and internal band. Particleboard properties that could favor the standards of consecutively Indoncia (SNI), Japan (JIS) and FAO either entirely or partially were density, moisture content, and MOR. The greatber the UF content, the more of those properties satisfying the JIS spesification. Judging from in density, this experimented particleboard was more suitable for ate at room deathing and frumed table-plane. The particielswars that looks the neust prospective for such purposesmere those ning UF at 8% content.

ARANG DAN CUKA KAYU PRODUK HASIL HUTAN BUKAN KAYU UNTUK MENINGKATKAN PERTUMBUHAN TANAMAN DAN SERAPAN HARA KARBON Sri Komarayati Gusmailina Gustan Pari Charcoal Wood Vinegar Carbon Absorption Growth Soil Charcoal and wood vinegar exert significant role as carbon sources yielded from the carbonization process, and afford multi benefits in their use for enhancing plant growth and stimulating carbon nutrient absorption. In relevant, this scientific narration presents results of trial tests employing charcoal and wood vinegar on the growth media for sprouts of sengon, jabon and agarwood producing plants, which lasted for 6 months at the planting experiment site. This experiment aimed to scrutinize the growth responses of such plant sprout species; and the examine the contents of carbon, nitrogen, phosphor, potassium in the soil and in plant biomass after being added with charcoal and wood vinegar. Charcoal addition proceeded by mixing it with soil evenly, while wood vinegar addition was done by showering it on to the soil. Nurturing of plants took place by spraying wood vinegar on their stems, branches, twigs and leaves. Results revealed that the additions of charcoal and wood vinegar on the growter media for sengon sprouts increased as much as 127-208% in beight and 109-129% in diameter of the corresponding sengon plants. For jabon plants, the addition of charcoal and wood vinegar brought about in increase 117-142% as much in their beight, and 166-128% in their diameter. Meanwhile, for eaglewood producing plants there appeared still no significant growth effect attributed by such addition, since it seemingly took considerable time for them to adapt themselves. Further, the incorporation of charcoal and wood vinegar brought about an increase of carbon nutrient adsorption in the soil and biomass. Besides carbon (C), adsorption of N, P, and K nutrients also increased.

PENAPISAN SENYAWA FITOKIMIA DAN PENGUJIAN ANTIOKSIDAN EKSTRAK DAUN POHON MERAPAT (Combretocarpus rotundatus (Miq.) DARI HUTAN KERANGAS Kissinger Evrizal AM. Zuhud Latifah K Darusman Iskandar Kerangas Forest Merapat Tree Species Leaves Antioxidant DPPh-Released Free Radicals The Control Antioxidant Vitamin C and BHT Kerangas forests typifies as tropical-rain vegetation trees, characterized by among others their low nutrients contents and sparse biodiversities, thereby denying their tree uses. The kerangas forests grow widespread in Kalimantan (e.g. South Kalimantan). Among the species that can grow and with stand such extreme condition is merapat (Combretocarpus rotundatus) trees. Their leaves contains particular chemical compounds that indicatively afford physiological bioactivities e.g. antioxidants. Consequentys this could expectedly emulate the added values for merapat tree uses. In relevant, scrutiny on phytochemical compounds and testing of such antioxidant efficacy were conducted on the samples of dry merapat tree-leaves taken from the kerangas forest in South Kalimantan. Initially, the dry leaves were extracted with methanol solvent, which yielded the methanol extract (i.e. sample 1), further fractionated by the column chromatography using chloroform eluant. The obtained chloroform-eluted fractions (sample 2) were fractionated again by the misced ethyl acetate-chloroform solvents (in equal proportion), which yielded the so-called sample 3. Phytochemical scrutiny revealed that the methanol extracts contained particular compounds such as flavonoids, phenol derivatives, bydroquinone, tannin, and triterpenoids, wich among them afforded the anticocidant efficacy. The methanol extract (sample 1) exchibited the very strongest antioxidant action by inflicting such reduction reaction on the free radicals released by the DPPH (2,2-diphenyl-1-picrylhydrazyl), while such action exerted by the chloroform-eluted fractions' sample 2 and the ethyl-acetate-chloroform-eluted fractions' sample 3 was very little. The inhibition of free-radical formation from DPPH as much as 50% (IC50) occurred at 21.82 ppm of the methanol-extract concentration. Meanwhile, vitamin C and BHT as the control antioxidants performed more efficiently at much less than 21.82 ppm (i.e. 6.74 and 6.28 ppm, respectively). However, such IC50 value strongly suggests that the merapat leaves' methanol extract afforded the potential bioactivity as antioxidant.

KETERAWETAN ENAM JENIS KAYU DARI JAWA BARAT DAN RIAU Krisdianto Didik Ahmad Sudika Ahmad Wahyudi Mohammad Muslich Preservation retention penetration digital image interpretation six wood species Preserving wood is one way to enhance its natural durability. The degree of wood protection achieved depends on the preservative impregnated in the wood and measured by its retention and penetration. Preservative retention is calculated based on the gravimetric system, while penetration is observed based on the colour differences after spot test. Preservative penetration pattern is observed visually and percentage is calculated conventionally. Digital image interpretation using Image-J software is one way to measure the preservative penetration. This paper studies the treatability of six wood species from West Java and Riau. Preservative penetration was interpreted both conventionally and digitally. Result shows hamirung, jaha and mahang putih wood species are classified into easy to preserve (class I), while bung bulang, pasang taritih and bira-bira wood species are classified asmediumto preserve (class II). Digital image identification provides easier, faster and more accurate in interpreting preservative penetration than the conventional method.

IDENTIFIKASI KOMPONEN KIMIA EMPAT KELAS MUTU GAHARU (KACANGAN A, TERI B, KAMEDANGAN A DAN KAMEDANGAN B) Totok K. Waluyo F. Anwar Agarwood Quality Sesquiterpene Chromone Agarwood signifies as one of the non-timber forest products (NIFPs) comodities in Indonesia. The form of agarwood varies, such as lumps, chips, flour, until oil. Agarwood in incense shape will give off smells, if burnt. This experiment aimed to identify chemical components in four grades of agarwood from the best to the lowest i.e. kacangan B, teri B, kamedangan A dan kamedangan B. Identification was performed by extracting the agarwood with acetone solvent, and then the acetone extract was fractionated using gradient column chromatography method with n-bexane-ethyl acetate as eluent. Identification of compounds proceeded using gas chromatography-mass spectrophotometer Results of identification revealed that there were sesquiterpene compounds in the four grades of agarwood (i.e. kacangan B, teri B, kamedangan A and kamedangan B), but kinds of compounds were different from one grade to other. Chromone compounds only existed in 2 grades of agarwood covering kacangan B ubich bad 2 compounds (6-bidroxy-2-methyl-5-nitrochromone), and 3-metaxxymethyl-2,5,5,8a-tetramethyl-6,7,8,8a-tetrabydro-5H-chromone), and kamedangan A with only one compound (2,2-dimethyl-6,7-dimetawcychromone). The presence of sesquiterpene and chromone with particular portion and characteristic in each of those four agarwood grades indicatively bears their role explaining their grades from the best until the lowest.

Consequently, use of alternative fibrous materials deserves thorough consideration, with their potencies abundant and mostly still unutilized, such as Nypa frutican midrib and coconut coir. In relevant, an experiment was conducted to utilize both kinds of fiber for MDE Those fiber stuffs were each passed through the preparation, and examination of their basic properties (i.e. specific gravity, chemical composition, and fiber dimensions and their derived values). The fibrous pulping for MDF employed a bat semi-chemical soda process under atmospheric pressure, followed with the refining action to achieve pulp freeness at 600-700 mil CSF. The refined pulp were then added with additives (i.z. 4% alum, 3% UF-adbesive, 5% activated charcoal), and then shaped into MDF mat using wet process, followed with beat treatment, bot pressing, conditioning, and ultimately the testing of MDF properties. Scrutiny on MDF physico-strength properties revealed that nypa-midrib fibers were more prospective for MDF than coconut-coir fibers. Activated-charcoal addition lowered the MDF formaldehyde-emission, but decreased its strengths. In properties, MDFs from nyta fibers significantly outperformed those from coconut-cnir fibers in complying with the standard (JIS). Yet, connut-nir fs could still in prospective for MDF by mixing them (pulp form) with nypa-fiber pulp at the proportion (w/w): 25%+75 and 50%+50%   BRIN Publishing 2025-07-10 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/12689 10.20886/jphh.2012.30.3.183-198 Jurnal Penelitian Hasil Hutan; Vol. 30 No. 3 (2012): Jurnal Penelitian Hasil Hutan; `182-197 2442-8957 0216-4329 eng https://ejournal.brin.go.id/jphh/article/view/12689/9979 Copyright (c) 2015 Jurnal Penelitian Hasil Hutan https://creativecommons.org/licenses/by-nc-sa/4.0/

KARAKTERISTIK PAPAN SANDWICH DENGAN INTI PAPAN PARTIKEL Ignasia Maria Sulastiningsih Dian Anggraini Indrawan Jamal Balfas Particleboard bamboo strips jabon plywood mahoni plywood veneer Bamboo has been recoqnized as wood substitute materials by convertting them into engineered bamboo products. Toincrease bamboo utilization efficiency, the waste generated from bamboo processing can be used further as raw materialsfor particleboard manufacture. Besides to get relatively thick and strong material, the bamboo particleboard can beused as a core layer for sandwich panel. The objective of this research was to determine characteristics of sandwichpanel with particleboard as the core layer. There were four types of particleboard used as the core layer of sandwichpanel i.e bamboo particleboard with density of 0.45 g/cm3(A1) and 0.55 g/cm3(A2), and the mixture of bamboojabon particleboards with density of 0.45 g/cm3(A3) and 0.55 g/cm3(A4). There were three types of outer layerof sandwich panel i.e. bamboo strips (B1), jabon plywood (B2), and mahoni plywood (B3). Sandwich panels wereproduced using urea formaldehyde adhesive. The results showed that bamboo-jabon particleboard used as core layerproduced stronger sandwich panels than those using only bamboo particleboards. Bamboo strips as the outer layerproduced stronger sandwich panels than those of using mahoni and jabon plywood. All sandwich panels produced inthis research conform to both the Indonesian Standard and the Japanese Standard requirements for particleboard withveneer overlay.

PENGUJIAN KETAHANAN BILAH BAMBU PETUNG (Dendrocalamus asper (Schults f.) Backer ex Heyne) TERHADAP JAMUR DENGAN CARA HAMPARAN TANAH Krisdianto Durability Bamboo Soil Bed Part of Culm Water Holding Capacity Durability performance is one of the important aspect of bamboo basic properties. As a lignocellulose material bamboo is susceptible to degrade by various organisms including fungi. Durability of bamboo is commonly assessed using wood laboratory testing procedure, such as agar plate method, an alternative soil bed test using unsterile soil is one attractive durability test method as it is cheap and simple to set up. This paper studies bamboo strips durability against fungus using soil bed test method. Bamboo strip tested were taken radially from inner (i), middle (m) and outer (o), and also longitudinally from bottom (B), parts of Dendrocalamus asper culms. The results show inner part strip (i) is more susceptible to fungi than the middle (m) and outer part (o). Almost all bamboo strips taken from inner part (1) failed to pin and hand bending test after six months exposure. Samples exposed in soil bed with 100% water bolding capacity decayed more severely than the 80% water bolding capacity. The bamboo strips from bottom (B) part were less susceptible than middle (M) and top (T) of bamboo height, bowever, the difference was not significant. Soil bed is an effective test method for bamboo strips durability against fungi.   BRIN Publishing 2025-07-10 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/12695 10.20886/jphh.2012.30.3.208-217 Jurnal Penelitian Hasil Hutan; Vol. 30 No. 3 (2012): Jurnal Penelitian Hasil Hutan; 207-216 2442-8957 0216-4329 eng https://ejournal.brin.go.id/jphh/article/view/12695/9985 Copyright (c) 2015 Jurnal Penelitian Hasil Hutan https://creativecommons.org/licenses/by-nc-sa/4.0/

PRODUKTIVITAS DAN BIAYA PENGELUARAN LIMBAH PEMANENAN KAYU PADA HUTAN ALAM PEGUNUNGAN: STUDI KASUS DI PT. JATI DHARMA INDAH PLYWOOD INDUSTRIES KABUPATEN NABIRE, PAPUA Soenarno Dulsalam Yuniawati Timber harvesting waste tree-length logging conventional productivity cost At present, logging activities have implemented Reduced Impact Logging (RIL) technology, but logging waste stilloccurs on average 17%. The logging waste has not been utilized because of the alleged high cost of production due toimproper wood harvesting method. This study aims to obtain data and information on productivity and skidding costsof wood harvesting waste in mountainous natural forest areas. The results showed that the cost of producing woodharvesting waste with the tree-length logging method at ± 2 hm skid distance was Rp 35,693/m3, but when usingthe conventional method is Rp 349,125/m3. The tree-length logging method can not only remove the main wood butalso free from branched wood waste (BBC) and trunk above the branch (BAC) till to landing site but also but it canincrease the efficiency of wood utilization. However, the application of the tree-length logging method resulted in adecrease in logging productivity of 16.47% and skidding of 14.41% at an average skid distance of 3 hm. The averageproductivity of logging in the conventional method is 62.514 m3/hour while the tree length logging method is 52.289m3/hour. The average productivity of skidding tree-length logging method is 17.301 m3/hour but the conventionalmethod is 18.249 m3/hour. For the tree length logging method to be implemented in the field, it is necessary to makechanges in the tariffs for felling and skidding wages following the reduced level of work productivity.

KLASIFIKASI MUTU 11 JENIS ROTAN INDONESIA BERDASARKAN KERAPATAN DAN KETEGUHAN LENTUR Rohmah Pari Abdurachman Jasni Titi Kalima Rattan Density Bending Strength Properties Characteristic Rattan is a lignocellulose plant that can be used for furmiture and other handicraft product. Quality and characteristics of the rattan species should be identified to comply with their utilization purposes. This research aimed to study the quality classification of 11 less used rattan species from Kalimantan, Sulawesi and Sumatera based on their physical properties (density) and mechanical properties (bending strength). The testing method applied was modified from ASTM D143-94. This modification was carried out because the formula used in ASTM is for square cross-section while rattan has cylindrical cross-section. The study of 11 species of rattan, based on the physical and mechanical properties, showed that three species of rattan from Kalimantan were classified in to class II – I (Calamus lobbianus), class III (Daemonorops fissa) and class IV – III (C. marginatus), while the three species of rattan from Sulawesi were grouped in to class I (C. robinsonianus), class II (C. scleracanthus) and class II – III (C. mindorensis). The remaining five species of rattan from Sumatera were categorized in class I – II (C. rugosus), class II – I (C. spectatissimus), class I – III (D. longipes), class II – III (D. verticillaris), and class III (D. sepal). These results could be used as a consideration for utilization of high quality rattan for furniture material that hold heavy load while low quality rattan may be used for holding light load only.

LACAK BALAK UNTUK VERIFIKASI UJI LEGALITAS KAYU PADA PEMANENAN KAYU HUTAN ALAM Soenarno Satria Astana Timber Harvesting Natural Forest Concession Log Tracking Tree Number Label LHP LHC Tree Stump Currently, timber trade requires that wood products must come from legally and responsibly managed forests. In Indonesia, to prove that wood products are legal if they are equipped with Legitimate Certificate of Forest Product, V-legal mark and electronic label in the form of Barcode. One method of proving wood origin in timber harvesting is log tracking method through labeling. This study examines the accuracy of log tracking in a Timber Forest Product Enterprise of Natural Forest (IUPHHK-HA) PT. Sumalindo Lestari Jaya II in Mahakam Ulu District, East Kalimantan Province. The log tracking was accomplished by tracking the comformity between wood documents in production result report (LHP), the numbered tree label attached on the stump till the cruising result report (LHC) document. Methods of sampling of LHP wood documents were conducted purposively through sample plots in three different felling sites. Results showed that timber traceability based on the LHP document to the tree number label attached on the tree stump wae 100%. However the level of log traceability from LHP documents to LHC documents ranges from 85.7–100% with average of 96.2%. Mismatch information between timber documents on LHP, the stump and LHC was mainly caused by wrong group of wood species and tree diameter classes.

PENGARUH PENGERINGAN TERHADAP PERUBAHAN WARNA, PENYUSUTAN TEBAL, DAN PENGURANGAN BERAT EMPAT JENIS BAMBU Adik Bahanawan Krisdianto Bamboo color changes thickness shrinkage water loss weight loss The surface color of bamboo stem changes naturally due to surrounding conditions. This paper studies the changesin bamboo surfaces color due to room temperature drying (KU) and oven drying (KO) at 60±2 °C. The color changesof four bamboo species: mayan (Gigantochloa robusta Kurz.), ater (Gigantochloa atter (Hassk) Kurz. Ex.Munro), ampel kuning (Bambusa vulgaris var. striata), and wulung (Gigantochloa atroviolacea Widjaja) werestudied together with their correlation to water loss. Color measurements were conducted based on CIE-Lab system,while water content related to weight loss and thickness shrinkage during KU and KO. The result showed that therewas a close relationship between water loss and discolouration of bamboo culms. The water loss of mayan, ater, andwulung showed a positive linear correlation to change of bamboo surfaces color, where the higher water loss affect greatervalue of color change too. Oppositely, in ampel kuning, higher water loss, affect smaller color change value (negativelycorrelated). This was because the natural color of ampel kuning in fresh conditions is not much different from colorafter drying. KU treatments, biggest thickness shrinkage was mayan = 46.03%; biggest weight reduction was ampelkuning = 28.52%; and biggest color changes (ΔE*) was ater = 15.51%. KO treatments, biggest thickness shrinkagewas mayan = 52.4%; biggest weight reduction was yellow ampel = 31.19%; and biggest color changes (ΔE*) wasater = 18.8%.

SINTESIS PEREKAT TANIN RESORSINOL FORMALDEHIDA DARI EKSTRAK KULIT POHON MANGIUM UNTUK PENINGKATAN KUALITAS BATANG SAWIT Okti Rachmawati Purwantiningsih Sugita Adi Santoso Tannin Acacia Mangium Bark Extract Adhesive Compregnation Oil Palm Trunk Oil palm trunk is lower in dimensional stability, density, physical, and mechanical properties than other wood species. Efforts to overcome the weakness of the oil palm trunk properties could be conducted through densification with hot pressing and chemical adhesive addition. This paper studies optimum composition of Tannin Resorcinol Formaldehyde (TRF) in its application for improving the quality of oil palm trunk. The tannins were water extracted at 75°C and further copolymerized with resorcinol and formaldehyde. TRF was studied through functional group analysis using infrared spectroscopy and cristallinity test using X-ray diffraction. The TRF adhesive was applied through compregnation process. Results showed that reactivity of tannins in bark of Acacia mangium was 65.82%, the optimum adhesive composition of TRF (v/v) was = 1:0.05:0.05 with solid content of 8.33%, 0.09% free formaldehyde, and the degree of crystallinity was 10.92%. Tannin extract has a specific character on the wave number corresponding to the characteristics possessed by the imported tannin acacia standard. The presence of new functional groups and an increase in absorbance intensity of uptake at several wave numbers through infrared spectroscopy analysis on TRF as well as compregnated oil palm trunk indicate the occurrence bonds attributted by ether and methylene bridges to TRF and chemical compound on oil palm trunk. Oil palm trunk after compregnation significantly increased its density by 104.61%, hardness became 6 fold, and decreased the thickness swell to 85.98%. The oil palm trunk after compregnation also increased in quality from a wood strength class V to a wood strength class III, then, its potential for manufacturing exterior products.

PEMBUATAN BIOETANOL DARI LIMBAH KAYU SENGON (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) DENGAN METODE SUBSTRAT KONSENTRASI TINGGI Ina T. Beuna Bardant Sengon Wood Waste Lignocellulose Hydrolysis Ethanol Content Various sawmilling industries of high, medium and small enterprises operate in Indonesia. During log conversion into sawn timber, wood waste occurs in the form of left over cut and sawdust. Small cut waste is lignocellulose material which is potentially used for bioethanol production. This paper studies the possibility of bioethanol production from sengon sawmill waste. High loading substrate method was applied by hydrolyzing high concentration substrate, i.e 15, 25 and 35% and two concentrations of enzymes (12.5 and 15 FPU/g substrate). Result showed that the treatment of 25% substrate concentration and 15 FPU/g cellulase substrate produced the highest reducing sugar of 248.3 mg/mL, while the substrate concentration of 35% generated the highest ethanol content i.e 17.7% and recovery about 38.4%. It can be concluded that the high loading substrate method could increase the ethanol concentration made from sengon wood waste.

COMPATIBILITY OF FOUR TROPICAL WOOD SPECIES AND SAGO STEM TO CEMENT AND PROPERTIES OF MANGIUM CEMENT BONDED PARTICLEBOARD Dede Hermawan1 Ismail Budiman Herman Siruru Jessica Hendrik Gustan Pari Cement board hydration temperature test physical properties mechanical properties The quality of the cement board depends on the compatibility between cement and particles fromlignocellulosic biomass. The purpose of this study was to determine the compatibility between cementand particles from four tropical wood namely mangium (Acacia mangium Willd), teak (Tectona grandisLinn. F.), gelam (Melaleuca leucadendron (L.), dadap (Erythrina variegata L.), and sago stem (Metroxylonsago Rottb.), and to determine the physical and mechanical properties of the mangium cement boardproduced by adding magnesium chloride (MgCl2) as an accelerator. This research was conducted intwo steps. The first step consisted of measuring the hydration temperature of a mixture of cement with particles from the four wood species and sago stems by adding magnesium chloride (MgCl2),with variations of 0%, 2.5%, 5%, and 7.5% based on the cement weight. Two types of mixturesfrom the first step were then used in the second step, namely the manufacture of cement board. The cement board was made using a weight ratio of mangium particles:cement:water of 1:2.7:1.35. Theboard is made with a target density of 1.2 g/cm3. Physical and mechanical testing refers to the ISO8335-1987 standard. The results of the hydration temperature showed that all of the mixtures wereclassified into “low inhibition”, except for mixture between cement and mangium particles without a catalyst which was included in the classification of “moderate inhibition”. While the results of cement board tests indicate that the cement boards made from mangium wood particles with 5%MgCl2addition had better properties compared to mangium cement boards without catalysts.

UJI COBA PENEBANGAN KAYU BERBASIS ZERO WASTE DAN RAMAH LINGKUNGAN PADA HUTAN ALAM DI PROVINSI KALIMANTAN TENGAH Soenarno Dulsalam Yuniawati Timber harvesting conventional zero waste environmentally friendly timber harvesting waste Over the last five years (2013−2017) there has been a deficit of ± 23.2 million m3year of wood raw materials,while the facts in the field of timber harvesting are still wasteful with leaving logging waste reaching an average of 17%of the annual production quota target of 9.1 million m3/year. The trial of zero waste-based and environmentallytimber harvesting method (ZWL) is important to strengthen the tree length logging methods. This research aimed toobtain data and technical information related to the efficiency of wood utilization and the potential of timber loggingwaste. The trial results showed that zero waste and environmentally timber harvesting methods could improve woodutilization efficiency by 9%, from an average of 82.9% to an average of 91.9%, and reduce the potential for clearbole (BBC) logging waste from an average of 12% (0.863 m3/ tree) to only 8.1% (0.418 m3/tree). In addition, itwas able to save the potential of logging waste from stems above the branch (BAC) ranging from 2.8−11.2% with anaverage of 6.4% (0.418 m3/tree). However, ecologically it could not reduce damage to residual stands which reached37.7% while conventional methods amounted to 38.8%. Potential logging waste both BBC and BAC were mostlydefective (50.5−58.3%), and some were still good (14.4−26.3%) while those with broken conditions were still quitehigh (22.6-27.3% ). Until now, the potency of timber harvesting waste has not been utilized due to the considerationof the high cost of Non-Tax Government Income (PNBP) levies, uncertainty in the application of the Minister ofEnvironment and Forestry Regulation Number: P.1/Menlhk/Setjen/Kum.1/1/2019, and the ZWL method hasnot been informed yet to minimize the cost of logging waste extraction. In order to reduce timber harvesting waste andresidual stand damage, the forest management refresh logging and skidding techniques to improve the skills of thechainsaw and the tractor operators.

KARAKTERISTIK LAMINASI BAMBU PADA PAPAN JABON Achmad Supriadi I.M. Sulastiningsih Subyakto Laminated Board Jabon Mayan Andong Physical and Mechanical Properties Jabon (Anthocephalus cadamba Miq.) has been widely planted by communities as an alternative of building and furniture materials. However, there are two inferior jabon wood proferties i.e. low strength (Class IV) and less durable (Class V). Jabon-Bamboo Laminated Board (JBLB) is one posible product that may be developed to improve jabon’s wood properties. This study investigates quality improvement of jabon boards due to fabrication as JBLB and the effect of bamboo layers number on JBLB properties. Andong bamboo (Gigantochloa pseudoarundinaceae (Steudel) Widjaja) and mayan bamboo (Gigantochloa robusta Kurz) were used in this study. Initially, jabon boards and 3 bamboo strips were preserved by soaking in 7% boron solution until reaching the targeted retention of 6 kg/m . The JBLB were manufactured in four different layer compositions using Isocyanate adhesive. The glue spread and cold pressing time 2 applied were 250 g/m and one hour, respectively. Results showed that quality of JBLB was significantly affected by the number of bamboo layers, except bonding strength. Bamboo lamination on jabon board has increased the product density by 10%, modulus of elasticity (MOE) by 71%, modulus of rupture (MOR) by 34% and compression strength by 20% compared with the initial jabon properties. Strength values of JBLB are classified into wood strength class-III .

KARAKTERISTIK LEMAK HASIL EKSTRAKSI BUAH TENGKAWANG ASAL KALIMANTAN BARAT MENGGUNAKAN DUA MACAM PELARUT Raden Esa Pangersa Gusti Zulnely Illpe nut's fat added value extraction organic solvent qualities Indonesian Illipe nuts or known as ‘Tengkawang’ is one of essential export commodities from the non-wood forest products group. Unfortunately such traded commodityis still in originalshapeor unprocessed fruits in dry condition, thereby imparting only small-added values. One way to enhance their traded values is by processing the fruits into so-called illipe nut's fat. Currently, the illipe nut’s process is through the extraction of the respective fruits (nuts) using organic solvents. Different kinds of organic solvent could presumably affect the qualities of the resulting-fat. This paper studies the illipe nut’s extraction using two solvents: benzene and hexane. The resulting fat was then examined for it's qualities, i.e. yield, physico-chemical properties and chemical component content analysis using GC-MS (gas chromatography-mass spectrometry) pyrolysis. Results revealed that the hexane produces greator yield of storage time. The illipe nut's fat lower acid value, free fatic acid (FFA) content and lower iod number than those of benzene. Low acid value, FFA, and the iod number creates the fat which is more resistant against hydrolytic and oxidative rancidity, and longer storage time. GC-MS analysis indicated that the chemical components in the benzene-extracted illipe nut's fat was dominated by methyl-octadec-9- oneate, while those in hexane-extracted fat by methyl oleate (compound with saturated C-C bonds).Judging from the overall results, it seems the use of hexane is more prospective as solvent toextract the fat fromillipe nuts than benzene.

This paper examines stand damage due to timber harvesting on hilly tropical forest, Central Kalimantan. The study was carried out using samples plot of 200 m x 100 m that was systematically placed on three selected cutting plots with different chainsaw operators working experience. Results showed that the degree of residual stands damage due to timber harvesting ranged between 19.37 – 34.9% with an average of 24.37% categorized as light stand damage. The average stands damage due to felling was 16.27% and skidding was 8.1%. Unexperienced chainsaw operators tend to cause greater damage than well trained chainsaw. Type of residual damage due to the felling on either sloping, rather steep or steep terrain was dominated by broken tree trunks. The most common type of residual stand damage due to skidding was the collapsed or tilted trees. The residual stand damage due to timber harvesting could be reduced by imposing intensive supervision in the felling sites and provide training and/or refresher to chainsaw and skidding tractor operators especially on cutting technique and environmentally friendly skidding.

KETAHANAN ALAMI JENIS-JENIS BAMBU YANG TUMBUH DI INDONESIA TERHADAP RAYAP TANAH (Coptotermes curvignathus Holmgren) Jasni Ratih Damayanti Rohmah Pari Subterranean Termites Weight Loss Percentage of Live Termites Durability Class Degree of Attack Natural durability of each bamboo species is different, thus information on natural durability of bamboo species is important for its utilization. This paper investigates the natural resistance of bamboo species against subterranean termites as a basis for species classification. Twenty species of bamboo from various regions in Indonesia (West Java, Banten, the Central of Java, Lampung and Bogor Botanical Garden) were tested against subterranean termites Coptotermes curvignathus Holmgren according to SNI 7204-2014. Parameters observed were weight loss percentage of bamboo, survival rate of the termites and degree of attack (subjectively). Results showed that based on the weight loss, three bamboo species could be grouped into resistance class I, five species into class II, three species into class III, seven species as class IV and two species as class V. Based on the survival rate of the termites, one of the bamboo species was classified in class I, four species in class II, one species in class III, 11 species in class IV, and three species in class V. Furthermore, according to the degree of attack, four species were heavily damaged, while 16 species showed moderately damage. From the result, it can be concluded that one species of bamboo namely apus (Gigantochloa apus) has the highest resistance class (class I), and four other species of bamboo namely hitam (G. atroviolacea), kuring (G. kuring), india/tulda (Bambusa tulda) and lemang (Schizostachyum brachycladum), were classified in resistance class II. In the utlization, the five species of bamboo can be used without preservation, while the remaining 15 species of bamboo in resistance class III V should be preserved before using.

KANDUNGAN MINYAK MALAPARI (Pongamia pinnata (L.) Pierre) DARI PULAU JAWA SEBAGAI SUMBER BAHAN BAKU BIODIESEL Aam Aminah Supriyanto Iskandar Zulkarnaen Siregar Ani Suryani Biodiesel Oil pHysico-Chemical Properties Pongamia pinnata (L.) Pierre Malapari (Pongamia pinnata (L.) Pierre) is one of the most potential biodiesel raw materials to be developed in Indonesia. The plant is natura ly distributed from Sumatera to Papua. However, oil content and its physico-chemical properties of malapari originated from Java was limitedly known. This study investigates chemical composition of malapari seeds, identifies fatty acid composition of the produced seed oil and characterises physico-chemical properties of malapari oil. Composition of chemical content of malapari seeds was analyzed through proximate analysis. Physico-chemical properties of malapari oil were analyzed using the ASTM test method. Results showed that Batukaras population is the best population to be used as biodiesel raw material source because it has the highest value of oil content. Besides, the Batukaras population has the lowest specific gravity, viscosity and acid value. Malapari oil is dominated by oleic and linoleic fatty acids which are potentia ly unsaturated fatty acids for biodiesel. Value of fatty acids (oleic and linoleic) and physico chemical properties (specific gravity and calorific value) of pongamia crude oils suggested that the five populations have been eligible for biodiesel feedstock.

PEMANFAATAN CAMPURAN BATANG JAGUNG DAN BAMBU SEMBILANG SEBAGAI BAHAN BAKU PAPAN PARTIKEL Dede Hermawan1 Jajang Sutiawan Nofrisman Jaya Putra Zendrato Robi’atul Utami Aini Ismail Budiman Kurnia Wiji Prasetyo Corn stalks particleboard phenol formaldehyde sembilang bamboo urea formaldehyde Corn stalk (Zea mays L.) can be used as an alternative material in the manufacture of particleboards. However,particleboards made from corn stalks has inferior mechanical properties which could not meet the Japanese standard(JIS A 5908: 2003). Such performance can be improved by adding other material which possesses high strength value,such as bamboo sembilang (Dendrocalamus giganteus Munro). This study examined properties of cornstalkparticleboard which was added into bamboo sembilang fibers in various compositions. Urea formaldehyde and phenolformaldehyde were used as binding agent with 10% adhesive content. Composition of fiber mixtures between corn stalkand sembilang bamboo were set in 100 : 0; 75 : 25; 50 : 50; and 25 : 75. The targetted density of particleboardwas set at 0.80 g/cm3. Mechanical properties of the produced particleboards were evaluated according to JIS A5908:2003 standard. Results showed that particleboard produced using composition of 25% corn stalk and 75%sembilang bamboo bonded with phenol formaldehyde had better mechanical properties than those of the other mixtureraw materials and adhesives. Additional high strength of lignocellulose material such as bamboo is one alternative toenhance mechanical properties of cornstalk particleboard.

KUALITAS DEMPUL ORGANIK DARI SERBUK KAYU JATI DAN SIRLAK Jamal Balfas Finishing Organic Wood Putty Teak Powder Shellac Tusam Rubber Wood Commercial wood putty products available in the market nowadays are mostly chemical solvent-based, such as epoxy and latex. These products give desirable physical, mechanical and chemical performances, however their volatile organic compounds are detrimental to the environment and harmful to the health. This paper explores the use of teak fine powder mixed with shellac and putty powder as an alternative formulation of organic wood putty. These alternative formulas were tested on tusam and rubber wood by assessing their physical, mechanical and chemical performances in comparison with the most commercial putty products, i.e. epoxy (DK1) and piroxylin (DK2). Samples of two wood species were treated by spreading them with various wood putty solutions. Weight and dimensional changes due to treatment were determined in wet and dry sample conditions. Results show that weight and dimensional gains due to spreading treatment varies according to wood species, grain orientation and putty solution. Tusam samples possessed greater weight and dimensional gains than those of rubber wood samples. All organic putty formula was able to protect wood from water intrution, but less effective than the commercial putty DK1 and DK2. The organic wood putty had lower scratch resistance and less resistant against chemical liquids than the commercial ones.

PENYEMPURNAAN SIFAT PAPAN SERAT BERKERAPATAN TINGGI DARI CAMPURAN RUMPUT GELAGAH, TANDAN KOSONG KELAPA SAWIT, DAN BAMBU Dian Anggraini Indrawan Han Roliadi Rossi Margareth Tampubolon Gustan Pari Adi Santoso Mohamad Iqbal Hardboard Saccharum Sponaneoun Grasses (SSG) Empty Oil-palm Bunches (EOPB) bamboo modification Laboratory-scale manufactured hardboard made of Saccharum Sponaneoun Grasses (SSG), Empty Oil-palm Bunches (EOPB), and andong bamboo is potentially developed. However, initial experiment shows the hardboard did not meet Japanese Industrial Standard (JIS) and International Standard Organization (ISO) for hardboard. This paper observes modification of the hardboard to satisfy the standards. Modification includes adding alkali concentration during pulp cooking and changing the additives composition. Result shows modification can enhance the hardboard quality to satisfy JIS and ISO requirements. Fiber mixture of SSG pulp and andong/betung bamboo pulp was cooked in 10.5% alkali concentration; and 12% alkali concentration for EOPB pulp. Additives composition used were tannin-resorcinol formaldehyde/TRF adhesive, alum, and activated charcoal; without wax emulsion. The mixture of SSG pulp (50%) + EOPB pulp (50%) was the most prospective for hardboard, followed by SSG pulp (100%) solely; SSG pulp (50%) + andong bamboo pulp (50%); and SSG pulp (50%) + betung bamboo pulp (50%) as the lowest prospects. The least prospective fibrous material (betung bamboo) are expectedly be improved by using more TRF adhesive, nano-size activated charcoal and cross-linking agents.

KARAKTERISASI STRUKTUR NANO KARBON DARI LIGNOSELLULOSA Gustan Pari Adi Santoso Djeni Hendra Buchari Akhirudin Maddu Mamat Rachmat Muji Harsini Teddi Heryanto Saptadi Darmawan Carbon Spark Plasma Sintering Intercalation Ligno-Cellulosic Stuffs The science advancement in this century is such that in the future it will enter the nano technology. More specifically in the forest products field, the nano technology that can be developed is among others nano carbon derived from lignocelulosic stuffs. In relevant, this research aims to provide information and technology on the charcoal processing from lignocellulosic stuffs into nano carbon. The lignocellulosic stuffs used in this research consisted of teak wood and bamboo, further carbonized into charcoal at 400-500°C using drum kiln. The resulting charcoal was examined of its physical and chemical properties, crystalinity degree and dielectric characteristics, and then purified by re-carbonizing it at 800°C for 60 minutes. Prior to the purification, the charcoal sustained the doping (intercalation) process with Zn, Ni and Cu metals each respectively. After the purification, the charcoal was ground to very tiny particels using HEM (high energy machine) device for 48 bours. In this way, the charcoal with high crystalinity was yielded, and further sintered using spark plasma at 1,300 C into the nano carbon. The qualities and structure of all the resulting carbon (carbonized charcoal, re-carbonized charcoal, intercalated charcoal and sintered nano carbon) were evaluated using nano scale device (Py-GCMS, SEM-EDX and XRD), and examined as well of their dielectric characteristics. In turns out that the best quality charcoal was obtained from teak wood charcoal carbonized at 800°C, intercalated with Ni atoms at the ratio 1:5. The resulting charcoal afforded high crystalinity (78.98%), low electric resistance (0.17 2), and high conductivity 175.52 2'm Qualities of the corresponding nano carbon (after sintering) were such that its crystalinity spectaculary reached 81.87%, resistance (R) 0.01 & with very bigh conductivity 1067.262'm'. The nano carbon that resulted seems favorably prospective for bio-censor, bio-battery, and bio-electrode. Accordingly futher related research deserves carrying out.

SIFAT FISIKA-KIMIA LEMAK TENGKAWANG DARI EMPAT JENIS POHON INDUK Raden Esa Pangersa G Evi Kusmiyati Illpe-Nut Fat Physical-Chemical Properties Extraction 4 Mother Tree Specirs Illipe nut in Indonesia still serves as one of the essential export commodities from the group of non-wood forest products. These nuts unfortunately are traded only in form of the dried fruits. Attempts are necessary to enhance the added value of illipe nuts. Among them is through the processing of the fruit into fat. One manner to extract the fat portion from the illipe- nut fruits is using organic solvent. In relevant, research was conducted on the extraction of illipe-nut fat from its fruit of 4 specier Shorea spp which was originated from the experiment station in Bogor, West Java. Fat extraction was conducted using bexane as the sohvent. The resulting fat was then examined for it physical-chemical properties and sustained the GC- MS (Gas Chromathography-Mass Spectrometry) analysis. The result revealed that the illipe-nut fat from 4 tree species varied in fat yield and its physical-chemical properties (Le. moisture content, acid number, free fatic acid and ind number). The GC-MS analysis indicated that illipe-nut fat contained various saturated fatty acid as well as unsaturated and other chemical compounds, such as phenol, aldebryde, bydrocarbon (aliphatic and cyclic) and hexane (presumably from the organic solvent). Oleic acid is dominant chemical component of S. stenoptera and S. parvifolia, metbyl oleate in S. pinanga and methylene-(4-trimethylsilanyl-phenyl)-amine in S. mecisopteryx.   BRIN Publishing 2025-07-10 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/12730 10.20886/jphh.2012.30.4.254-260 Jurnal Penelitian Hasil Hutan; Vol. 30 No. 4 (2012): Jurnal Penelitian Hasil Hutan; 254-260 2442-8957 0216-4329 eng https://ejournal.brin.go.id/jphh/article/view/12730/10019 Copyright (c) 2015 Jurnal Penelitian Hasil Hutan http://creativecommons.org/licenses/by-nc-sa/4.0/

SELEKSI JAMUR PELAPUK PUTIH HUTAN TROPIS INDONESIA SEBAGAI PENGHASIL ENZIM LAKASE (Lac) DAN MANGAN PEROKSIDASE (MnP) Lisna Efiyanti Asep Hidayat White-Rot Fungi Enzyme Isolate Lac MnP White-rot fungus, Basidiomycetes is an unique group of microbes among the major decomposers of plant polymers or biomass. Their existences are under pressure due to Indonesian tropical forests degradation caused by forest fires, excessive exploitation, land conversion and biopiracy. Based on natural process of white rot fungi, it could be utilized for bioresources, i.e improvement of food quality and leading of new functionality (the food industry), delignification (pulp & paper), production of ethanol (biofuel), biosensors and bioremediation. This paper studies isolate, selection and evaluation of the potential extracellular enzymes laccase (Lac) and manganese peroxidase (MnP) from fungi grown in Indonesian tropical forest. A total of 178 samples of fungi fruit were collected from Indonesian tropical forest, including West Java, East Java and East Kalimantan Provinces, then they were isolated and selected on RBBR agar media for futher analysis. The results showed that there were significant differences of 26 pure isolates, in term of its capacity to decolorize RBBR, and only six pure isolates (JB-7.1.1, BST-F16, Gr-W3.2A-C, TRK-1, TRK-2, and TRK-3) were able to oxidize RBBR more than 1 cm per day. Futhermore, two isolates were selected as their enzymes production was higher than another, those were -1-1 JB-7.1.1 (Lac = 526 ± 142 UL and MnP = 114 ± 13 UL ), and TRK-2 (Lac = 463 ± 95 UL and MnP = 98 -1-1 ± 8 UL ). Statistically, the activity of Lac produced by JB-7.1.1 was higher and not significantly different with the positive control, Cerrena sp. F0607. JB-7.1.1 and TRK-2 isolates were the potential fungi for producing Lac, which they could be applied easily for textile dyes decolorization as bioremediation.

SIFAT FISIS DAN MEKANIS PAPAN UNTAI BERARAH DARI BAMBU TALI ( (J.A. & J.H. Schultes) Kurz) Gigantochloa apus I.M. Sulastiningsih Dian Anggraini Indrawan Jamal Balfas Adi Santoso Mohammad Isa Iskandar Bamboo OSB Phenol Formaldehyde Resin Content Strand Length Physical and Mechanical Properties Bamboo is potential as an alternative material to substitute wood. This paper examines the effects of using different resin contents and strand dimensions on the properties of its oriented strand board (bamboo OSB). Tali bamboo (Gigantochloa apus (J.A. & J.H. Schultes) Kurz) was used as raw material in manufacturing the bamboo OSB. Laboratory scale oriented bamboo strand boards were fabricated using each bamboo strand length (7.5, 10, and 15 cm) and glued with liquid phenol formaldehyde adhesive at various resin contents (6, 7 and 8%) of the bamboo strands dry 3 weight. Results show that the average density of fabricated bamboo OSB was 0.75 g/cm . Physical and mechanical properties of bamboo OSB were significantly affected by resin content, except the modulus of elasticity (MOE). Higher resin content gave better physical and mechanical properties of the boards. MOE of bamboo OSB was also significantly affected by the strand length. The longer strand dimension produces boards with higher MOE values. All oriented bamboo strand boards studied meet the Indonesian and Japanese Standard requirements of type 24 particleboard and also meet the British Standard requirements of both Type OSB/2 and Type OSB/3.

STUDI PENYADAPAN GETAH PINUS CARA BOR DENGAN STIMULAN H2SO4 Mody Lempang Pine Resin Tapping Drilling Method H2SO4 Stimulant In general, pine resin yield is affected by various factors i.e. pine tree species, growing environment and tapping method. This paper studies pine resin tapping yield by drilling method using H₂SO₄ stimulant. Tapping point is designed in the depth of 4, 6 and 8 cm and sloping 25°. Three stimulant concentrations (0, 15%, 30%) were brushed in the tapping point and the treatments were repeated 10 times. Experimental design based on 3 × 3 factorials in completely randomized design. The first factor is the depth of drilling holes, the second factor is the concentration of H₂SO₄ stimulant used and repetition of 10 times. Pine resin yields were analyzed using analysis of variance and further test was conducted by honestly significant difference test. Results show that tapping pine by drilling and stimulant addition produced pine resin between 15.5 to 109.3 g / tree / collection (56.3 g / tree / collection on average) or between 2.6 to 18.2 g / tree / day (9.4 g / tree / day on average). Pine resin yield is significantly influenced by drilling hole depth and H₂SO₄ stimulant concentrations. The deeper the drilling hole, the more pine resin yield, and the higher the concentration of H₂SO₄ stimulant the higher pine resin yield. Pine resin yield of 8 cm tapping depth is 65.96% higher than 4 cm tapping depth, and 30% H₂SO₄ improved the yield by about 56.45%. The largest pine resin yield is achieved from tapping point of 8 cm depth and 30% H₂SO₄ that yiled about 90.7 g / tree / collection in average.

KARAKTERISTIK FISIS DAN MEKANIS GLULAM JATI, MANGIUM DAN TREMBESI Nurwati Hadjib Abdurachman Efrida Basri Glulam teak mangium trembesi wood structural This paper studies the physical and mechanical characteristics of the glued-laminated (glulam) beams made from small diameter of three fast growing species i.e. teak (Tectona grandis L.f), mangium (Acacia mangium Willd.) and trembesi/monkeypod (Samanea saman Merr.) using water based polymer isocyanate (WBPI) as a binder. Six plies of wood combination species were laminated into final dimension of 6 cm × 12 cm × 300 cm. Each laminate was graded using Machine Stress Grading (Pantek, plank sorter) to determine its Modulus of Elasticity (MOE). Cross-section of two type of glulam beam was 6 cm × 12 cm, arranged of various widths and based on values of laminate MOE. Results show that the average and range value of the glulam density were 0.658 g/cm³ and 0.557-0.821 g/cm³, with the moisture content of 14.6% (13-16.8%). The average of the glulam modulus of elasticity and modulus of rupture were 75.51 (37.016-120.446) kg/cm² and 494 (145-750) kg/cm² respectively. The glulam made from teak has better MOE and MOR performances compared to those of mangium and trembesi. In general, the results showed that almost all of glulam beams tested meet requirement of JAS (Japanese Agricultural Standard) 2007 for structural glulam in moisture content, MOE, MOR, and shear strength. The glulam qualities can be classified into E65-E95-F225-F270, except for several species combination beams. Based on the strength classified and the ratio of S/W, the glulam can be used as a construction material except glulam teak-trembesi (preserved or unpreserved) and the unpreserved trembesi-trembesi. The three types of glulam can be utilized for the lightweight construction.

KAJIAN STRUKTUR ARANG-PIROLISIS, ARANG-HIDRO DAN KARBON AKTIF DARI KAYU Acacia mangium Willd. MENGGUNAKAN DIFRAKSI SINAR-X Saptadi Darmawan Wasrin Syafii Nyoman J Wistara Akhirudin Maddu Gustan Pari Activated carbon pyrolized-char hydro-char XRD analysis mangium wood Activated carbon has been used widely for various applications. Hydro-char which is hydrothermally carbonized from biomass could be used as an alternative precursor for activated carbon manufacture, which is commonly obtained from pyrolized-char. This paper observes crystalline structure of Acacia mangium’s pyrolized-char and hydro-char using XRD (X-raydiffraction). The mangium wood was carbonized in 200°C and 300°C and depth analysis was conducted based on activated carbon product. Result shows carbon maturity index and aromaticity from both precursors (conventional and alternative) tends to increase after being activated; interlayer spacing (d002) is getting closer; meanwhile, crystallinity is greater; and the number, height as well as width of aromatic layers are increasing. Hydro-char exhibited crystallinity degree, maturity and aromaticity lower than those of the pyrolized-char obtained at 300°C carbonization, with the greater volatile content. Both types of char perform carbon structure with amorphous texture. The greatest iodine adsorption is achieved by hydro-char which was carbonized at 300°C. In general, XRD analysis on low temperature carbonization of pyrolized-char and hydro-char could predict the porosity of activated carbon.

ANALISIS HASIL PENGUJIAN KAYU YANG DISERANG PENGGEREK KAYU DI LAUT DENGAN INTERPRETASI GAMBAR DIGITAL Krisdianto Listya Mustika Dewi Mohammad Muslich Natural durability marine borer digital image nine wood species class durability Natural durability is determined through the tests of wood against wood attacking organisms. Natural durability of wood against marine borer was tested by exposing wood into the open sea water for six months. Damage intensity can be measured on the basis of digital image using Image-J software. This paper studies natural durability of nine wood species from Sumatera, Java and Kalimantan against marine borer. Results show that sempur lilin (Dillenia obovata Hoogl.), bambang lanang (Michelia champaca L.var. pubinervia) and kayu babang (Azadirachta excelsa (Jack) Jacobs) were classified into class durability I (very resistant), while cangcaratan (Lithocarpus sundaicus (Blume) Rehd. and avengekalakai (Shorea pervustipulata ssp. albifolia) were classified into class durability II (resistant) against marine borer. Ki pasang (Prunus javanica Miq.) and segelam (Hopea rudiformis) were grouped into class durability III (moderately resistant), while ki biwang (Arthophylum diversifolium Blume) and ki langir (Otophora spectabilis Blume) fall into class durability V (perishable). Damage intensity could be measured accurately using Image-J software. However, this method obtained higher damage percentage since the ex-rope hole was included in the measurement. Accordingly, the image method should be modified by excluding the ex-rope image to achieve high accuracy measurement.

SIFAT FISIK KAYU MANGLID (Manglieta glauca Bl.) PADA ARAH AKSIAL DAN RADIAL M. Siarudin Ary Widiyanto Axial Moisture Content Physical Properties Radial Specific Gravity Study on physical properties of manglid (Manglieta glauca Bl) wood on axial and radial orientation has been conducted. Three manglid trees were taken as samples from community forest in Sodongbilir Village, Sodongbilir Sub-district, Tasikmalaya Regency, West Java. The observation focused on physical properties on three positions of both accial orientation (bottom, midle and top of trunk) and radial orientation (near pith, middle and near bark). The parameters observed were fresh moisture content, air dry moisture content, and wood dimensional changes. Result shows that the average of fresh moisture content of manglid wood is 168.77%, air dry moisture content is 14.63%, specific gravity on fresh volume is 0.35, specific gravity on air dry volume is 0.36 and specific gravity kiln dry volume is 0.38. Based on its dimensional changes, manglid wood bas longitudinal shrinkage value of 1.51%, radial shrinkage value of 4.08%, tangential shrinkage value of 5.84%, and ratio of tangential and rudial shrinkage of 1.54. Physical properties of manglid wood on axial and radial orientation are varied for fresh miosture content and specific gravity, while the air dry moisture content and the dimensional changes are not significantly different. The trend of fresh moisture content value on axial orientation is increased from the bottom to the middle of the trunk, and then decreased ot the top of the trunk. On radial orientation, the fresh moisture content value consistently decreases from the pith to towards the bark. Specific grafity value on the axial orientation decreases from the bottom of the trunk to the midle, then increases on the top. In radial orientation, the specific gravity gravity ralue consistently increases from the pith towards the bark.

PEMANFAATAN GULMA LAHAN GAMBUT SEBAGAI BAHAN BAKU BIO-BRIKET Pranatasari Dyah Susanti Reni Setyo Wahyuningtyas Adnan Ardhana Weeds peat swamps bio-briquettes qualities examined parameters Weeds are abundantly available, which grow on peat swamps, but unfortunately have not yet been widely utilized. Those weeds can be prospectively potential as raw material for bio-briquettes. In relevant, this research aimed to look into the qualities of bio-briquettes manufactured from 10 species of peat swamp weeds. Initially, each weed species was carbonized and then shaped into charcoal powder. The resulting weed-charcoal powder was then mixed with wood sawdust at 1:1 ratio (w/w), and agitated thoroughly to obtain homogenous stuff. Afterwards, the homogenous stuff was added with starch-derived binder (adhesive). Such adhesive was previously prepared by heating 5 g tapioca-starch flour in 75 ml of water. The starch-added stuff was then pressed into bio-briquette, and further put in the oven at 60°C for 24 hours, or just dried under the sunlight heat for 2 days. The parameters as examined on the dried bio-briquette comprised calorific value, moisture content, fixed-carbon content, ash content, and sulfur content. Results revealed that the weeds of purun tikus (Eleocharis orrostachys Steud.) species was regarded as the best for bio-briquette manufacture, as it excelled other species in the overall examined parameters, i.e. calorific value (4,647.9 cal/g), fixed carbon (25.63%), moisture content (5.48%), ash content (8.78%) and sulfur (0.55%).

PEMURNIAN BEBERAPA JENIS LEMAK TENGKAWANG DAN SIFAT FISIKO KIMIA Raden Esa Pangersa Gusti Zulnely Refining illipe nut's fat physical-chemical properties Illipe nut in Indonesia serves as one of the essential export commodities from non-wood forest products group. Illipe nut through the extraction can be processed into high-economic valued fat that could function as cocoa butter substitute (CBS), obtained through extraction of illipe nut Illipe nut's fat that results from extraction process can not be directly used, but should be previously refined. In this study, refining of illipe nut's fat was conducted through degumming and neutralization process. Degumming process was carried out by adding acids (acetic, citric and phosphoric) each with 20% strength at 0,4% (w/w) to the fat that has been previously heated. The results showed that degumming using phosphoric acid produced a better quality fat compared to that with citric acid and acetic acid. NaOH was used for neutralization process. The resulting neutralized fat was then examined for its physical-chemical properties which revealed that such properties were not so far different from those of commercial illipe nut's fat. The GC analysis as conducted on the refined illipe nut's fat showed that it consisted of various saturated fatty acid as well as unsaturated and other chemical compounds. All of the examined illipe nut's fat in this research showed that oleic acid is the dominant component.

PENGARUH PERLAKUAN DELIGNIFIKASI TERHADAP HIDROLISIS SELULOSA DAN PRODUKSI ETANOL DARI LIMBAH BERLIGNOSELULOSA Luciasih Agustini Lisna Efiyanti Bioconversion bioethanol delignification enzymes fermentation Delignification signifies as the crucial stages in converting lignocelluloses into ethanol. It affects further hydrolysis and fermentation processes. This paper looks into the effects of three different delignification processes (physical-, chemical-, and biological- treatments) of lignocellulosic biomass (i.e sawdusts of sengon and oil-palm petioles) on cellulose hydrolysis and fermentation. Physically, biomass was pressurized in an autoclave which has been set for 121°C, 1 atm for 30 minutes. Chemically, 1% H₂SO₄ was added during pressurized process. Biologically, pressurized biomass was inoculated using microorganism MD-14 FB.1 obtained from INTROF-CC collection For the control, biomass stuffs without chemical, physical, and biological treatments, sustained the hydrolysis/fermentation process as well. Delignification properties with regard to α-cellulose, lignin, hemicellulose contents in the treated as well as control biomass were examined according to the ASTM procedures. The amount of glucose exhibited from cellulose hydrolysis was determined by 3,5-dinitrosalicylic acid method, while the ethanol content was determined by potassium dichromate method. Results show that in general, chemical delignification is more effective than physical and biological treatments. It shows greater yield of lignin decomposition and sugar liberation in hydrolysis. Chemical delignification treatment produced about 0.0022 - 0.4046% ethanol from the substrate fermentation. The enzyme produced from the isolations has not significantly optimized the ethanol fermentation. Further research is needed in finding the compatibility between lignocellulose biomass and enzymes which were developed from microbe isolates.

Tampubolon Wood Wastes Eucalyptus Hybrid Insulation Board Chitosan Glue (adhesive) From Ahrimp Exoskeleton This study examined characteristics of insulation board manufactured from the mixture of wood astes from Eucalyptus bybrid plantation forest (PF) logging and activated charcoal, and the adhesive as used was chitosan derived from the shrimp exoskeleton. PF-logging's wood wastes were reduced in size to chips, then made into pulp using open bot soda chemical process at the condition being alkali (NaOH) concentration at 8%, wood to liquor ratio 1:8 (w/v), and maximum cooking temperature 100C held for 3 hours. Insulation-board mat was formed using the wet process from the miscture of PF logging's wood wastes and activated charcoal at the proportions (w/w) consecutively 100% +0%, 97,5% + 2,5%, 95% + 5%, 92,5% +7,5%, dan 90%+10%. Prior to mat forming, to the miscture were added 2 kinds of adhesives separately (i.e. chitosan and tapioca as the comparison) 5% each. Physical and mechanical properties of the resulting insulation board with tapioca were better than those with chitosan. The greater the portion of activated charcoal mixed to the PF-logging's wood wastes, the lower the density and the strength (MOR), the more increased the moisture content, but the more improved the dimensional stability. The insulation board which revealed the most promising prospects and could favorably meet the JIS specification was the one from the mixture proportion of PF-logging's wood wastes and activated charcoal at 97.5%+ 2.5%, uring tapioca adhesive, and the one from solely 100% PF-logging wastes (without activated charcoal) using chitosan.

KEMUNGKINAN PENGGUNAAN ANTIOKSIDAN GUNA MEMPERTINGGI KETAHANAN OKSIDASI BIODIESEL DARI MINYAK BIJI TANAMAN JARAK PAGAR (Jatropha curcas L.) Han Roliadi R. Sudradjat Arum Anggraini Fossil Fuel Alternative Sources Jatropa Curcas Seed Oil Estrans Biodiesel Antioxidants Characteristics The excperiment has been done to look into the utilization of Jatropa curcas oil for biodiesel as the alternative of the fossil-based diesel oil through the estrans (esterification and transesterification) process and the use of antiocidants. The estrans process brought about favorable changes in the oil characteristicus (eg, the decreases in density, viscosity, acid number, and iod number), thereby enhancing its performance as biodiesel. Three kinds of antioxidants were used (i.e. TBHQ, BHT, and Formula X), each with varying concentrations (0.03- 0.10%), and storage duration were imposed from the first until fourth week. The examined responses comprised of peroxide number, acid number, and kinematic viscosity. Reaching the fourth week, however, the wcidation process still occurred to the biodiesel oil despite using antioxidants (slight increases in peroxide number, acid number, and kinematic viscosity), but with the intensity far less than that of the control biodiesel (without antioxidant). The antioksidant regarded as the most effective inhibiting, such oxidation was TBHQ, followed in decreasing order by BHT and Formula X. However, the Formula X could expectedly perform as effectively as TBHQ and BHT, but with higher concentration (0.10%). The characteristics of biodiesel either the control or with antisocidants (up to the fourth week duration) could still satisfy the SNI criteria and those of fossil-based diesel oil.   BRIN Publishing 2025-07-10 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/12781 10.20886/jphh.2012.30.1.69-86 Jurnal Penelitian Hasil Hutan; Vol. 30 No. 1 (2012): Jurnal Penelitian Hasil Hutan; 69-86 2442-8957 0216-4329 eng https://ejournal.brin.go.id/jphh/article/view/12781/10066 Copyright (c) 2015 Jurnal Penelitian Hasil Hutan https://creativecommons.org/licenses/by-nc-sa/4.0/

Hence, a specific effort is required to increase the JCTquality. This research is aimed to improve the quality of JCT and rubber wood through impregnation of extracts and resin.This study used extracts from traditional teak wood sawdust dissolved in methanol solution. The teak extractive solutions were then impregnated into wood structure of JCT and rubber wood with various solution concentrations according to additional organic resin. The organic resins used in this study consist of shellac and damar, which were added at three weight concentration levels of 4, 6 and 8% of the extract volume. The results show that the impregnation of extractive solution into JCT and rubber wood increased dimentional stability of both woods with Anti Shrink Efficiency (ASE) value exceeds 50%, compared to the traditional teak. The addition of shellac and damar resin in the teak extractive solution significantly result in better dimensional stability of both treated woods proportionally in accordance to the resin concentration.

PENGARUH ARANG DAN CUKA KAYU TERHADAP PENINGKATAN PERTUMBUHAN DAN SIMPANAN KARBON Sri Komarayati Gusmailina Gustan Pari Charcoal wood vinegar seedlings nutrients soil The research aimed to look into the growth responses of sengon, jabon, and agarwood seedlings; and to examine the carbon (C), nitrogen (N), phosphor (P), and potash (K) contents in soil as well as in the biomass portions of those three plant species (i.e. their leaves, stems, and roots) after being added with charcoal and wood vinegar. It also intended to explore the potency of carbon store in such plant-biomass portions. The charcoal addition was conducted by mixing it with soil evenly and homogenously, while wood-vinegar incorporation proceeded by spraying it onto the soil. For taking care of the plants, the wood vinegar was sprayed periodically to their stems, twigs, and leaves. Results revealed that the growth of sengon seedlings achieved the greatest in height (156.33 cm) and in diameter (20.08 mm), attributed to the addition of wood vinegar (2%) and charcoal (10%). For jabon seedlings, the greatest growth in height (89.17 cm) and in diameter (19.22 mm) occurred due to addition of wood vinegar (4%) and charcoal (20%). For agarwood seedlings, the greatest growth height (72.20 cm) and in diameter (18.29 mm). Besides, the addition of charcoal and wood vinegar could not also bring about the increase in consecutively nutrient contents (e.g. C, N, P. and K), biomass weight, and carbon store, which varied in the leaves, stems, and roots, in accordance to the percentages/ dosages of those two agents as added.

PENGGUNAAN STIMULAN DALAM PENYADAPAN PINUS Sukadaryati Gunawan Santosa Gustan Pari Dodik Ridho Nurrochmat Hardjanto Inorganic stimulant ETRAT wood vinegar tapping pine sustainability For the formulation of policy strategies on the use of environmentally friendly stimulant in the production of pine resin, the study of innovation stimulant is a necessity. This study aimed to identify the use of stimulants made from a strong acid (inorganic), ETRAT and wood vinegar on pine tapping. Research results revealed that the use of stimulants could increase resin flux and extend. Inorganic stimulant produced resin more than ETRAT and wood vinegar per collection in area with elevation above 500 ASL and below 500 ASL. The use of inorganic stimulant, however, caused the change of wood colour that will be dark brown to reddish even that going into as far as to the pith of wood. Meanwhile, the use of organic stimulant doesn't cause the change of colour in wood significantly. Therefore the use of stimulants on tapping pine needs to consider the negative effects of trees's health, workers and the environment.The economic aspect that should be persued to achieve the financial target, is not the main factor only but the ecological and sosial aspects to achieve a yield sustainability and tree producing are requared.

HUBUNGAN KETAHANAN KAYU TERHADAP JAMUR DENGAN KERAPATAN DAN PENGKARATAN LOGAM Sihati Suprapti Abdurahman Djarwanto Riau wood decaying fungi resistance class wood density metal screw corrosion Wood constructions are mostly fastened by metal screw or metal fastener, then corrosion resistance is an importantfactor. Wood natural durability against fungus and its relation to basic density are two other factors affecting woodquality for construction. This paper studies wood natural durability against fungus and metal corrosion in relation todensity of five Riau wood species. Wood samples were tested against fungus using the Kolle-flask method and wooddensity was measured based on DIN-2135-1975 standard. Result shows that Diospyros korthalsiana wood wascategorized as non-resistant (class IV), Tetramerista glabra wood was classified as moderately resistant (class III),while Shorea teysmanniana, Palaquium burckii, and Aglaia argentea woods are grouped into resistant wood(class II). In all wood species, weight lost of heartwood is lower than that of sapwood, but in the same durabilitygroup (moderately resistant). In general, there is a relationship between density and weight loss. The higher the wooddensity is the lower the weight loss. The average of weight loss of metal screwed wood is higher than wood withoutscrews. The highest weight loss was recorded from Palaquium burckii wood which was screwed and exposed toPolyporus sp., while, the highest screw weight loss was recorded from Shorea teysmanniana wood exposed toPycnoporus sanguineus. Rustic enamel was highly recorded from Tetramerista glabra wood, which was exposedinto Tyromyces palustris. Eight species of fungus are moderate and two species are low in capability of decayingwood. The highest decaying ability in corroding metal screws is found in P. sanguineus. The weight of rustic enamelfound in the metal screw caused by four fungus activity of (Chaetomium globosum, P. sanguineus, S. communeand T. palustris) was relatively similar.

KARAKTERISTIK MADU LEBAH HUTAN (Apis dorsata Fabr.) DARI BERBAGAI BIOREGION DI RIAU Avry Pribadi M. Enggar Wiratmoko Forest honey Riau bioregion characteristic Indonesian National Standard (SNI) Characteristics of Apis dorsata`s forest honey from bioregions of Riau have not been studied intensively. Thisresearch is aiming to provide characteristic information on honey from bioregions of Riau based on SNI 8664-2018.The study was conducted in September to November 2015. Honey samples were collected from eight districts of sixbioregions in Riau Province, i.e Bengkalis and Selat Panjang (downstream), Kampar (mineral forest), Pelalawan(peat swamp forest), Rokan Hilir (river bank), Siak (Acacia plantation forest), and Kuansing (oil palm and rubberplantation). Samples of each bioregion were analyzed based on SNI 8664-2018 procedures. Results show that wildhoney characteristics were not significantly different among bioregions for almost all parameters in SNI 8664-2018.However, the diastase enzyme parameter in honey taken from Pelalawan was the only parameter that had significantvalue. In addition, the parameter of water content and reducing sugar content were only two parameters that did notmeet the SNI 8664-2018 requirements. Meanwhile, the type and size of pollen could be used for determining the originof honey between Riau bioregions.

KOMPONEN KIMIA SEPULUH JENIS KAYU KURANG DIKENAL : KEMUNGKINAN PENGGUNAAN SEBAGAI BAHAN BAKU PEMBUATAN BIOETANOL Arya Sokanandi Gustan Pari Dadang Setiawan Saepuloh Lesser-known wood species 10 examined species bioethanol basic properties (chemical composition) technically feasible Lesser known wood species refers to the woods already utilized much by the communities but confined only one or two of uses, generally as sawn timber and merchant wood. Consequently, diversification attempts are necessary to impart more added values to these species. One of the possibilities for such is their uses for bioethanol manufacture. In relevant, research was already performed to look into the possible utilization of 10 local lesser-known wood species, which comprised pangsor (Ficus callosa Willd.), jengkol (Pithecellobium rouslatum Kosterm.), petai (Parkia speciosa Hassk.), mami (Maesopsis eminii Engl.), balsa (Ochroma grandiflora Rowlee), ki cauk (Pisonia umbellifera (Forst) Seem.), buru manuk (Litsea monopeIata Pers.), kei renghas (Buchamania arborescens Blume), kei bonen (Crypteronia paniculata Blume ) dan ki hampelas (Ficus ampelas Burm.f.), as raw material for bioethanol. In assessing for bioethanol manufacture, it necessitates initially the data/ information on basic properties of each wood species, particularly the chemical composition, which was examined through the wood chemical analysis in accordance with the accepted standar, i.e. Norman Jenkin, Indonesian National Standart (SNI) and TAPPI. Analysis result on those 10 woods revealed that the cellulose content varied about 42,03-54,95%, lignin 22,66-35,20%, pentosan 15,36-17,15%, water content 3,95-10,99%, ash content 0,56-2,89%, silica content 0,12-0,84%. Solubility in cold water 1,29-5,55%, solubility in hot water from 4,41-11,19%, solubility in alcohol-benzene from 2,95-4,60% and solubility in NaOH 1% 10,35-22,89%. For bioethanol manufacture, it is desired that the woods base high values of consecutively cellulose and pentosan content, and solubility in NaOH 1%; and concurrently have low content lignin, ash and silica, low solubilities in cold water, hot water and alcohol benzene. Judging from those criteria and aided by the statistics interpretation, it indicates that 8 out of 10 species were technically prospective as raw material for bioethanol, i.e. from most until the least being kei rengas, mami, petai, jering, balsa, ki hampelas, ki cauk, and burumanuk, respectively. Meanwhile, kei bonen and pangsor are regarded as unsuitable for bioethanol.

SINTESIS DAN KARAKTERISASI BORNEOL DARI α-PINENA GETAH PINUS (Pinus merkusii Jungh. & de Vriese) Gunawan Pasaribu Totok K. Waluyo Lisna Efiyanti α-pinene borneol resin synthesized Pine resin is obtained from a process of tapping the pine tree (Pinus merkusii Jungh. & de Vriese). After processing, pineresin will produce gondorukem and turpentine. Currently, the utilization of turpentine is mainly for cosmetic, paint, a mixture ofsolvents, antiseptics, and pharmaceuticals. Due to an increase in the added value of the turpentine product, turpentine wassynthesized into borneol. This study aimed to analyze the characteristics of borneol produced from the synthesis of α-pinene usingNaOH and KOH bases. The method was carried out by synthesized α-pinene into borneol through sodium reduction using twoalkali e.i KOH and NaOH. The compounds were characterized by FTIR, NMR and GCMS. The results showed that onFTIR analysis of 12 samples of the borneol synthesized showed fairly similar absorption peaks with peaks appearing on standardborneol FTIRs. The NMR analysis of both HNMR and CNMR, compared with the standard NMR compounds α-pinene,champor and borneol, show that the peaks still show differences. The GCMS result showed the formation of the compound ofborneol compound with the percentage of 0.12 to 2.2% relatives. The type of base and origin of the turpentine used did not showany difference in borneol yield.

ANALISIS BIAYA PENEBANGAN SISTEM SWAKELOLA: STUDI KASUS DI DUA IUPHHK-HA KALIMANTAN TENGAH Soenarno Cost Analysis Tree Felling Self-Managed System Contract System Natural Forest To improve the efficiency of timber harvesting process, forest industries have implemented tree length logging technique. Unfortunately, the effort in utilization as much as the tree parts has not been followed by minimizing the production cost, for example in the felling process. Industries apply a full contract felling system by involving third party even it is considered as an expensive cost. A solution of this problem is by implementing self-management felling system. This paper studies the felling cost conducted by third party and self-management. The study was carried out at two natural forest concessionaires (IUPHHK-HA) Central Kalimantan. Results reveal that self-managed felling system in both 3 3 IUPHHK-HA PT. A and PT. B costed about IDR 4,051.11/m and IDR 6,800.11/m , respectively. This cost is, 3 cheaper than the contract felling system which is ranged from IDR 6,000 to 7,000/m . Hence, for cost efficency, implementing self-management felling system is recommended.

HONEYCOMBING AND DEFORMATION OF SIX WOOD SPECIES AND THEIR RELATIONSHIP WITH SEVERAL PHYSICAL PROPERTIES Karnita Yuniarti Efrida Basri Abdurachman Honeycombing Deformation High Temperature Drying Defect Predictor It is presumed that the wood susceptibility to drying defects is related to several physical properties. This paper examines the drying defects: honeycombing and deformation of six wood species (trema, fast growing teak, bayur, jabon, angsana and lamtoro) during high temperature drying and analyses their relationship with initial moisture content, T/R shrinkage ratio and density. Terazawa method was used to examine the defect during high temperature drying. Result shows that after high temperature drying, lamtoro suffers the worst honeycombing (level 4-6), and fast growing teak deforms severely (level 4-6). Regression analysis shows multiple regression models using all physical properties as predictors provides better estimation on deformation and honeycombing than single-predictor regression models. The multiple regression model for each defect could explain 57.52% and 39.46% of variation in deformation and honeycombing, respectively.

FORMULASI RAGI CAMPURAN UNTUK PRODUKSI BIOETANOL DARI LIMBAH KAYU SENGON Ina Winarni Sri Komarayati Djarwanto Yeast Mixing Sengon Wood Waste Commercial Yeast Fermentation Ethanol Currently, bioethanol is one of biofuels which is potentially developed for new and renewable alternative energy. Bioethanol could be fermented from agriculture and forest wastes, with pre-treatment and hydrolysis process before the fermentation. Those process could be carried out by an addition of microbe (yeast). In order to gain greater ethanol content, yeast mixing formulation is crucial to obtain optimum ethanol content. This paper studies the formula of yeast mixing for optimum ethanol production of sengon wood waste. Formulation was conducted by mixing Aspergillus oryzae, Saccharomyces cerevisae, Rhyzopus oryzae and other substances with various treatments. Commercial yeast of 3 – 9% Sacharomyces cerevisae was used as a comparable control. Results showed that 7% yeast mixing was effective to produce 1.569% ethanol content from lignocellulose fermentation. The ethanol content is relatively greater than those of commercial yeast which constitutes of about 0.652% ethanol content.

SIFAT DAN MUTU ARANG AKTIF DARI TEMPURUNG BIJI METE (Anacardium occidentale L.) Dewi Alimah Cashenut Shell Activated Charcoal Properties and Quality Indonesian National Standard Currently, cashew nut (Anacardium occidentale L.) shell is abundantly available as waste from chasew nut processing industries. Theoretically, cashew nut shell is potentially used for activated charcoal. This paper studies the properties and quality of activated charcoal made from cashew nut shell. The study also evaluates processing condition in producing optimum quality of activated charcoal. Initially, cashew nut shells were collected and carbonized in 500°C for 3 hours. Then, the charcoal was activated in temperatures of 800°C, 900°C and 1000°C for 30, 60 and 90 minutes. The data were then analyzed using analysis of variance and Tukey test for further significance test. Results show that chasew nut shell could potentially be used for commercial activated charcoal. The optimum quality of shell's activated charcoal was obtained by activating the charcoal in 1000°C for 90 minutes, that produced charcoal with properties of 0.40% moisture content, 8.85% volatile content, 77.40% fixed carbon content and 131.35 mg/g of methylene blue adsorptive capacity. Almost all charcoal's properties met the quality requirement stated in the Indonesian National Standar (SNI 06-37301995) except those of three properties: ash content (13.75%), benzene adsorptive capacity (2.93%) and adsorptive capacity of iodium (703.73 mg/g).

SIFAT FISIS DAN PENGERINGAN LIMA JENIS BAMBU Efrida Basri Rohmah Pari Bamboo Physical Properties Drying Defects Drying Temperature Information regarding physical properties of bamboo is essential for interpreting its dimensional stability, while drying properties are needed as a basis in determining the optimum drying temperature. This research was aimed to investigate the effect of bamboo species and position at the culm on physical properties, as well as drying properties of five bamboo species i.e. temen bamboo (Gigantochloa verticillata Munro), ori (Bambusa blumeana Bl. ex Schult.f.), ater (Gigantochloa atter (Hassk.) Kurz ex Munro), ampel (Bambusa vulgaris Schrad.), and peting (Gigantochloa levis (Blanco) Merr.). Physical properties were tested by measuring diameter and thickness of bamboo culms. Determination of drying temperature was carried out in accordance with wood drying method and followed by observing visual defects, i.e. deformation (concave & wrinkle) and end/node split. Assessment results revealed that there were close relationships between green moisture content of bamboo and their density as well as their culm shrinkage. Based on bamboo drying properties (bottom-middle portions), the optimum drying temperatures (initial and final temperature) for temen and ori were occurred at 45 – 70°C, ampel and ater were occurred at 40 – 60°C, while the optimum drying temperature for peting were at 33 – 50°C   BRIN Publishing 2025-07-17 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/jphh/article/view/12808 10.20886/jphh.2017.35.1.1-13 Jurnal Penelitian Hasil Hutan; Vol. 35 No. 1 (2017): Jurnal Penelitian Hasil Hutan; 1-13 2442-8957 0216-4329 eng https://ejournal.brin.go.id/jphh/article/view/12808/10091 Copyright (c) 2015 Jurnal Penelitian Hasil Hutan https://creativecommons.org/licenses/by-nc-sa/4.0

KUALITAS HARDBOARD DUA JENIS BAMBU DENGAN TAMBAHAN TANIN RESORSINOL FORMALDEHIDA Dian Anggraini Indrawan I.M. Sulastiningsih Rossi Margareth Tampubolon Gustan Pari Adi Santoso Hardboard Bamboo Tannin Resorcinol Formaldehyde Physical and Mechanical Properties All kinds of ligno-cellulose fiber stuffs are technically suitable for hardboard manufacture. In Indonesia, currently the available conventional ligno-cellulose fibers (esp. tropical natural-forest woods) become scarce and depleted. Meanwhile, domestic fiberboard-production is lower than its demands. Alternative fibers, abundantly potential and largely still unutilized, should be introduced, e.g. bamboo. Research on bamboo utilization for hardboard has been carried out using two bamboo species i.e. tali bamboo (Gigantochloa apus) and ampel bamboo (Bambusa vulgaris). Each bamboo species was pulped using open hot-soda semi-chemical process. Five proportions of bamboo pulp mixtures were prepared from tali-bamboo pulp and ampel-bamboo pulps i.e: 100%+0%, 75%+25%, 50%+50%, 25%+75%, and 0%+100%. Tannin-resorcinol-formaldehyde (TRF) adhesive was added to each bamboo pulp mixtures at three different resin contents, i.e. 0%, 6% and 8% based on dry weight of the bamboo pulp mixture. Bamboo hardboards were manufactured using wet forming process and the resulted boards were then tested for their physical and mechanical properties. Results showed that addition of TRF (up to 8%) improved hardboard properties. Hardboard made from the ampel-bamboo pulp (100%) produced the highest hardboard quality, as its properties mostly conform with the standards (JIS and ISO) requirements for density, modulus of elasticity (MOE), modulus of rupture (MOR) and internal bond (IB); while hardboards made from tali-bamboo pulp (100%) possessed the lowest quality. Hardboard from tali-bamboo pulp and ampel-bamboo pulp mixture (at 50%+50% and 25% + 75% proportions) afforded the second and third performances. The least prospective tali-bamboo pulp (100%) could expectedly be improved by using more TRF.

KUALITAS POLITUR ORGANIK DARI EKSTRAK KAYU JATI DAN SIRLAK Jamal Balfas Organic Wood Finishing Teak Extract Shellac Scratch Resistance Color Currently, commercial wood finish products are predominantly chemical solvent-based, such as melamine formaldehyde and nitrocelulose. Although these products give desirable quality, durable and affordable cost, their volatile organic compounds are detrimental to the environmental and harmful to the health. This paper studies the use of teak extract mixed with shellac as alternative top coat or wood stain. Quality of the alternative formula was tested on tusam and rubber wood by assessing their physical, mechanical and chemical performances in comparison with the commercial products, i.e. melamine formaldehyde (MF) and nitrocellulose (NS). Samples of two wood species were treated by dipping them in various wood finishing solutions. Weight and dimensional changes due to the treatment were determined in wet and dry sample conditions. Results showed that weight and dimensional gains due to dipping treatment were varied according to wood species, grain orientation and finishing solution. Tusam samples possed greater weight and dimensional gains than those of rubber wood samples. All organic finishing formulas were able to protect wood from water intrution, however they were less effective than the commercial MF and NS. Top coat made from the mixture of teak extract and shellac has lower scratch resistance and less resistant against chemical liquids than the commercial MF and NS. Wood stain of teak extract and shellac mixture provided better color value than the commercial wood stain in term of color likeness to the true teak.

PENGARUH KOMPOSISI ARAH LAPISAN TERHADAP SIFAT PAPAN BAMBU KOMPOSIT I.M. Sulastiningsih Surdiding Ruhendi Muh. Yusram Massijaya Wayan Darmawan Adi Santoso Bamboo composite lumber layer orientation bonding quality physical and mechanical properties The objective of this study was to determine the effect of layer orientation composition on the properties of bamboo composite lumber (BCL). Bamboo strips for BCL fabrication were prepared from mature culms (± 4 years old) of andong bamboo (Gigantochloa pseudoarundinacea (Steudel) Widjaja) collected from private gardens in West Java. The strips were pre-treated by soaking it in 7% boron solution for 2 hours. Five-layer BCLs were manufactured with 4 different compositions of layer orientation. The BCL was manufactured using water based polymer-isocyanate (WBPI) adhesive. The glue spread and cold pressing time applied were 250 g/m² and 45 minutes, respectively. Results showed that the average density, moisture content, thickness swelling, and width expansion of BCL were 0.79 g/cm³, 12.60%, 2.38%, and 1.13%, respectively. No delamination occurred in all samples using WBPI adhesive, which indicating high bonding quality. The average bonding strength (dry test) of BCL was 70.4 kg/cm². The physical and mechanical properties of BCL were significantly affected by layer orientation composition. The mechanical properties of BCL decreased as the number of cross-layer increased in the BCL structure. On the contrary, the present of cross-layer in BCL structure increased dimensional stability of the produced BCL.

LEMAK TENGKAWANG SEBAGAI BAHAN DASAR LIPSTIK R. Esa Pangersa Gusti Totok K. Waluyo Commercial Lipstick Formulation Illipe Nut's Fat Organoleptic Test Physical Properties Cocoa butter has long been used as a base ingredient for lipstick. Illipe nut's fat is known to have similar characteristics to those of cocoa butter, thus expectedly, it could be used as an alternative substitute for cocoa butter in lipstik manufacturing. This paper studies the appropriate Illipe nut's fat formulation for lipstick manufacturing. Water-based (WB1, WB2, WB3, WB4) and oil-based (M1, M2, M3, M4, M5) formulations with illipe nut fat content of 2, 3, 4 and 5% were tested. The illipe nut's fat was produced from Shorea pinanga collected from West Java. Physical properties (i.e hardness and melting point) and organoleptic test (texture, shine, polish ability, odor and color) were analyzed. The results showed that M3 formulation with 2% illipe nut's fat level had similar physical properties to those of commercial lipsticks. Furthermore, the organoleptic test revealed that M5 formulation with 3% fat level was the most preferred by respondents. To obtain lipsticks performance which meets the requirements in commercial lipsticks criteria and also satisfies the respondent's preference, a combination of M3 and M5 formulation is recommended.

HIDRORENGKAH MINYAK LAKA MENGGUNAKAN KATALIS NiO/ZEOLIT ALAM AKTIF DAN NiOMoO/ZEOLIT ALAM AKTIF MENJADI FRAKSI BERPOTENSI ENERGI Darma Santi Lisna Efiyanti ZAA catalyst unimetal and bimetal impregnation cashew-nut shell liquid hydrocracking Hydrocracking of cashew-nut shell liquid (CNSL) into energy-affording fractions has been investigated using catalyst of acid-actiated natural zeolite (ZAA), to which were further impregnated unimetal (NiO) and bimetal (NiOMo) elements, thereby comprising two catalyst types (NiO/ZAA and NiOMoO/ZAA). This research aimed to examine how potential was the conversion of CNSL into energy-affording fractions, and to look into such metal impregnation into ZAA catalyst on the performance of hydrocracking reaction. Catalyst characterization included determining consecutively acidity using ammonia-base adsorption, and crystallinity using X-ray diffraction (XRD). Acid activation and metal impregnation increased the catalyst acidity and its crystallinity. The hydrocracking was carried out in a fixed-bed reactor employing the temperature 450°C, the CNSL feed/catalyst ratio of 6, and flow rate of H₂ at 20 ml/minute. The hydrocracking converted the CNSL into products that comprised the liquid-phase, gas-phase, and solid-phase (cokes) fractions, which in all afforded energy, and the conversion of each was examined. The liquid-phase product was further analyzed using gas chromatography (GC), which revealed that the GC's eluted liquid fraction were predominantly gasoline, diesel oil, and heavy oil. Each eluted fraction was further examined for its selectivity based on the elucidated GC area for each fraction over the total GC area for the overall liquid fractions. The hydrocracking performed optimally using NiOMo/ZAA catalysts. Which converted as much 75.42% (the greatest) of the CNSL as the liquid product, with also the greatest in selectivity towards gasoline and diesel-oil fraction at 38.45% and 19.87%, respectively. The impregnation of metal element, particularly bimetal (NiOMo) into ZAA catalyst indicatively enhanced the hydrocracking performance.

PENGAWETAN KAYU TISUK (Hibiscus macrophyllus Roxb.) MELALUI RENDAMAN DINGIN DENGAN BAHAN PENGAWET BORIC ACID EQUIVALENT Endah Suhaendah M. Siarudin Retention penetration cold immersion tisuk wood preservation Tisuk (Hibiscus macrophyllus Roxb.) is one of fast growing tree species widely planted in private forest mainly in Java Island. However one of the weaknesses of tisuk wood is the low durability which is categorized as durability class of III/IV. This paper studies the durability improvement of tisuk wood using Boric Acid Equivalent (BAE) with cold immersion method. The tisuk wood samples were taken from a private forest in Sukamulih Village, Sariwangi Sub-district, Tasikmalaya Regency. The treatments applied were wood thickness (thickness of 2.5 cm, 5 cm, 7.5 cm and 10 cm); immersion time (3 days, 5 days and 7 days); and two preservative concentration (5% and 10%). Each treatment was replicated in 10 specimens (total of 240 specimens). The parameters measured were the retention and penetration of preservative solutions. The analysis of variance shows that the retention of the preservative solutions was significantly different for the wood thickness treatment but it was not significant for other treatments (immersion time and preservative concentration). Meanwhile, the penetration of the preservative solutions was not significantly different for all of the treatments. The retention and penetration of the preservative solution fulfilled the minimum standard required by Indonesian National Standard for wood preservation in all treatments. Based on the analysis, the wood preservation method recommended for tisuk wood using boron and boric acid solutions is 3 days of duration of immersion with concentration of 5% for all of wood thickness treatments (2.5 cm, 5 cm, 7.5 cm and 10 cm).

FAKTOR EKSPLOITASI HUTAN DI SUB REGION KALIMANTAN TIMUR Soenarno Wesman Edom Zakaria Basari Dulsalam Sona Suhartana Yuniawati Exploitation Factor Natural Forests Reduced Impact Logging Sub-Region East Kalimantan Forest harvest is the first activity to undertake in extracting logs from the forest site. The amount of wood wastes generated during logging operation can be used for measuring the value of exploitation factor (FE). The greater FE indicates more efficient of wood utilization. Indonesian government has so far decided the formal FE is 0.7. This value is no longer accurate for the current better forest management situation which adopting practices of reduced impact logging-RIL and or RIL-C. Considering from economic aspects, the FE value has a very important role, i.e. as multiplying factor in determining annual allocation of wood production (JPT) and as a basic parameter in predicting earn business provision of natural forest (PSDH). Ecological aspects may interprete that the bigger FE value will bring about reduction of forest damages. This paper examines the FE in Sub-Region of East Kalimantan. Results show that the proper FE value for the East Kalimantan Province is ranged between 0.77 – 0.89. The amount of FE value is more influenced by factor of feller skills than the management competence factor of IUPHHKHA.

PERAN GLUKOMANAN-ARANG AKTIF SEBAGAI HIPOKOLESTEROLEMIK PADA TIKUS SPRAGUE DAWLEY Agus Malik Ibrahim Irma Herawati Suparto Tetty Kemala Gustan Pari Cholesterol Reduction Glucommanan Amorphophallus Activated Charcoal Sprague Dawley Rat Cholesterol is a metabolite which contains sterol fat, which is important to support cell functions and generate vitamin D, cortisol and reproduction hormones. Higher cholesterol content known as hypercholesterolemia is a predisposing towards cardiovascular disease. Previous study reported that glucommanan and activated charcoal individually can lower cholesterol levels, however combination both of them for lowering the cholesterol level has not been studied intensively. This paper examines the ability of glucommannan derived from Amorphophallus flour and activated charcoal in reducing cholesterol level of Sprague Dawley rat. Firstly, glucommanan was isolated from Amorphophallus flour and activated charcoal was produced from teak sawdust and coconut fiber. Both component were formulated and characterized using Fourier Transform Infra Red (FTIR), x-ray diffractometer and scanning electron microscope. Thirty five adult male Sprague Dawley rat with body weight of 160 to 200 g were divided into seven treatment groups: high-fat diet (DTL) and glucommanan, DTL and teak's activated charcoal (TC), DTL and cocout fiber's activated charcoal (CC), DTL and glucommanan and CC (1:1), DTL and glucommanan and CC (2:1), DTL and glucommanan and CC (1:2) and DTL without treatment as control. Initial rat cholesterol level was measured and it was compared with those after five weeks. Results show that the greatest cholesterol reduction (37.4%) is recorded from rat with DTL and glucommanan and CC (1:1) and low density lipoprotein reduction by about 49.7% and triglyceride reduction by 18.3%.
