EVALUASI PETA PERCEPATAN GEMPA SUMATERA (SNI-1726-2002) TERHADAP PETA PERCEPATAN GEMPA MENGGUNAKAN SOFTWARE PSHA Aldiamar, Fahmi SNI-1726-2002 Sumatra Probabilistic Seismic Hazard Analysis (PSHA) Evaluation on seismic hazard map in Sumatra bedrock was needed because the Indonesian seismic hazard map standard (SNI-1726-2002) was built using the 2D seismic source model and a lot of seismic activity around Sumatera occurred after the 8N1-1 7 26-2002 was published. Probabilistic Seismic Hazard (PSHA) software was developed by USGS in 2007 to gain bedrock acceleration value derivedf rom Probabilistic calculation on 3D seismic source using the Next Generation Attenuation (NGA). Therefore this software represented the newest theory to build seismic hazard map and it was used in this research to evaluate and validate the Indonesian standard, particularly Sumatra seismic hazard map. Several phases were done to gain the seismic hazard map, such as collecting and processing earthquake data, calculating seismic risk parameter, acceleration calculation using PSHA software and developing a seismic hazard map using ArcGis Software. Evaluation result indicated that SNI-1726-2002 seismic hazard map in Sumatera bedrock, particularly in region 3,4 and 5 was lower than seismic hazard map developed using PSHA software. The deviation was range between ± 0.05-0.20g.

PENINJAUAN NIETODE PERHITUNGAN AWAL BULAN KAMARIAH KRITERIA MUHAMMADIYAH DENGAN KAJIAN ASTRONOMI Sasongko Adhi, Arief Moon Crescent Hilal Muhammadiyah Astronomy Muhammadiyah has long used a method which is based on the calculation of the conjunction of the Moon and the Sun to determine the beginning of Islamic months. If the conjunction happens before sunset and sunset happens before moonset, then the next day is the beginning of an Islamic month. Such a method often produces dates of the beginning of Islamic months which are earlier than the actual visibility of the lunar crescent. This research was conducted to compare the determination of the beginning ofIslamic months produced by different criteria. The criteria compared were Muhammadiyahs', Lapan's, SAAO's, and Odeh's. Astronomical data needed were obtained from Accurate Times 5.1 software for Cibinong area as the location of reference. Calculations were performed to determine the beginning of Islamic months starting from Sha'ban 1429 until Shawwal 1430. Comparison of the dates produced by the four criteria shows that those calculated by Muhammadiyah .'s criterion yielded in five differences out of 15 data points observed. It calls for a review on the criterion.

ANALISIS ANOMALI SINYAL ULTRA LOW FREQUENCY (ULF) GEOMAGNET SEBELUM TERJADI GEMPA 29 SEPTEMBER 2004 DI BIAK Nuraeni, Fitri Seismo-electromagnetic ULF, Earthquake Polarization method Ultra Low Frequency (ULF)  anomalies on geomagnetic variation data can be caused by external disturbances such as from the sun or space and internal disturbances from the earth. Before the 5.4 Richter Scale earthquake at Biak on September 29, 2004, there are anomalies that might be caused by electromagnetic emission from the earth's inner layer. These anomalies have been detected on geomagnetic signal in ULF band (10 — 600 sec periods). This paper will discuss the anomaly that was detected before the earthquake, and whether it was a local event within the earth's inner layer that happened because of the earthquake's preparation phase or was it actually caused by external disturbances. Data that is being used is the H and Z component of geomagnetic data variation. The Fast Fourier Transform method (FFT method) is being used to process the geomagnetic signal so the data can be filtered by bandpass filter. The Z/H polarization method is being used to analyze the result. Dst and Kp indices are also used to determine whether the anomaly is caused by external or internal disturbances.   BRIN Publisihing 2026-08-18 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/widyariset/article/view/16048 10.14203/widyariset.12.1.2009.17-22 Widyariset; Vol. 12 No. 1 (2009): Widyariset; 17-22 2461-0976 eng https://ejournal.brin.go.id/widyariset/article/view/16048/12263 Copyright (c) 2009 Author(s)

MODIFIKASI PEMBENTUKAN LAPISAN Zn PADA PERMUKAAN BAJA DUAL FASA DENGAN NITRIDASI RINGAN Dimyati, Arbi Dual phasesteel Hot-dip galvanising Electron microscopy Bright nitriding In this work an experimental series was performed in order to modify the surface properties and galvanise ability of the dual-phase steel by the nitriding in an ammonia containing atmosphere (bright nitriding) during re-crystallisation annealing. The samples were characterized using various electron microscopy techniques and special preparation methods. The investigations show that during re-crystallization annealing with a relatively short duration because the nitrides formation with a large amount of nitrogen atoms can incorporate into the surface near area of the steel. The steel microstructures and the oxidation behavior of the alloying elements on the steel surface are positively changed. The decreasing of oxidation causes the surface activation that increases the steel/zinc reactions during hot-dipping. The formation of the Fe7415 inhibition layer also changes. The best quality of the zinc layer surfaces are achieved on the samples after annealing with ammonia concentration between 0.25 and 1 vol.-%. Therewith a new alternative for controlling the hot-dip galvaniseability of highstrength steels are proposed.

PENGEMBANGAN SIMULATOR UNTUK PENGENDALIAN REAKTOR DAYA TIPE PWR Deswandri PWR Load Following Operation Control Method Simulator Axial Offset The load following operation is a mode of operation, where the power level of nuclear power reactor is adjusted based on the load fluctuation at the electric grid. The changes of power level cause unbalance in the reactor. In order to keep the stability of reactor, it needs a specific control method. Three control methods for the PWR type reactors were developed for that purpose. Each method was tested by a numerical simulation, respectively. Since these methods were tested separately, however, it is difficult to compare the performance of all methods directly using the same initial parameters and various standard power patterns. In this work, we developed the simple simulator to simulate the control methods of PWR during the load following operation. By using the standard daily power patterns, it was showed that the simulator could be used well and all results agree with the previous results of the three control methods above. By using the same initial parameters and power pattern, the simulator could directly show the characteristic, superiority and disadvantage of each control method, respectively.

ANALISIS KEHANDALAN STRUKTUR BANGUNAN WISMA ATLIT RAGUNAN PASCA KEBAKARAN Rusli, Muhammad Post-fire Construction Concrete Field Testing Structural Analysis The data acquisition of the post-fire construction is done by visual observation, dimension measure-ment, concrete field testing and also laboratory testing. Visual observation above the third floor which is directly on fire, indicate serious damages with the result that all of the building component above the third floor must be replaced by a new construction. The testing of building material shows that the grade of concrete component which is directly fired has fc '=6.8 MPa, while the non-fired component has fc'=15.2 MPa. The structural analysis shows that most of the building components at the first and the second floor are able to be functioned with a little repair of longitudinal balk at their support section to increase bending capacities.

TRANSFORMASI GEN ARABIDOPSIS ASYMETRIC LEAVES2 (AS2) PADA ANGGREK PHALAENOPSIS AMABILIS (L.) Blume DENGAN MEDIATOR AGROBAKTERIUM TUMEFACIENS Esti Windiastri, Vincentia Arabidopsis ASYMMETRIC LEAVES2 gene transformation Agrobacterium tumefaciens Phalaenopsis amabilis leafshapes The Asymmetric leaves2 (AS2) gene is an important gene of a model plant, Arabidopsis thaliana, that involved in leaf development. To understand the molecular mechanism of leaf development in orchid, we transformed the AS2 gene into the Phalaenopsis amabilis orchid protocorms (developing orchid embryos). Agrobacterium tumefaciens LBA4404 that contained T-DNA with 355:: AS2 construct and pGreen vector were used for transformation. The-21-day-old protocorms that co-cultivated with Agrobacterium culture containing pG35S::AS2/LBA 4404 and pG35S/LBA4404 were maintained on 100 mg/1 kanamycin containing medium. The growing plants were selected as candidate of transformants. The putative transformants were analysed by PCR with a pair of AS2 gene specific primers (ORF15 F2 and ORF I 5 R2), that amplifying 600 by fragment of AS2 gene. The result showed that 79 plants out of 7966 protocorms transformant p35S: : AS2 and 64 plants out of 4622 protocorms transformant pG35S were kanamycin resistants, the efficiency of transformations were 0.99% and 1.38%, respectively. Phenotype characterization of the transformation showed that they produced various abnormal leaves shapes: oval (34.18%), wildtype-like (30.38%), rectangular (26.58%), lobed (3.80%), fused (2.53%) and trumpet (2.53%). These data indicate that abnormal shape of leaves might be due to the expressions of AS2 transgene in P amabilis.

Penggunaan ilmu pengetahuan dalam proses produksiakan meningkatkan kapasitas, efisiensi, dan efektivitas produksi. Lebih dari 50% pembentuk PDB di negara majuadalah kegiatan ekonomi yang berbasis produksi dan distribusi ilmu pengetahuan. Indonesia menyadari pentingnyailmu pengetahuan dalam pembangunan ekonominya dengan menetapkan visi dan misi “Terwujudnya MasyarakatTelematika Nusantara Berbasis Pengetahuan di Tahun 2020”. Tetapi, visi dan misi itu sendiri tidak cukup tanpadiikuti pelaksanaan dan komitmen yang kuat yang tercermin di dalam kebijakan pemerintah. Tulisan ini bermaksudmereview kebijakan pemerintah terkait dengan pemanfaatan ilmu pengetahuan untuk pembangunan ekonomi,utamanya dalam hal teknologi dan inovasi serta pendidikan dan pembagunan sumber daya manusia dengan menggunakananalisis kualitatif berdasarkan data sekunder. Pembangunan teknologi dan inovasi di Indonesia beradapada posisi yang terendah dibandingkan negara lain di Asia. Kebijakan yang telah dijalankan rezim pemerintahanterdahulu bisa dikatakan tidak berhasil karena terlalu berfokus pada pembangunan teknologi tinggi, padahal, tidaksepenuhnya benar bahwa semakin tinggi teknologi maka semakin tinggi pula dampak ekonomi yang dihasilkan,hal ini akan tergantung pada sektor apa teknologi tersebut diterapkan.

KEKUASAAN PRESIDEN (Studi Komparatif RI dengan Beberapa Negara Maju) Ghoffar, Abdul Presidents Head of state Power (social scienees). The Presidential power after the amandment of 1945 Constitution has decreased. Many people think thatsuch decreases are excessive because in practice, majority of the president’s policy requires approval of the Parliementary,making the President has difficulty in running the government. To avoid confusion, the researcher isinterested in conducting research related to the presidential power of the President of Indonesia compared to thepower of head of state/and or head of government in eight developed countries, namely the United States, Russia,Japan, China, Kuwait, Australia, and South Africa. In conducting the research, the researcher uses reseach methodsof juridicial, historical and comparative approaches. The result of this study indicates that Indonesian Presidentialpower is quite enormous compared to the power owns by the head of states and / or head of governments in theabove mentioned countries. Only Kuwait Amir’s power can defeat Indonesian Presidential power. The power ofKuwait Amir is similar to Indonesian Presidential power before 1945 Constitution amandment.

INDONESIAN BIODIVERSITY AND BIOTECHNOLOGY: LIPI Update Hakim, Lukman Keanekaragaman hayati Sumber daya genetik Bioteknologi Bioteknologi tumbuhan Therapheutics protein Gen tahan flu burung Indonesia adalah negara dengan keanekaragaman hayati terbesar di dunia (mega diversity country). Negeri ini sudah sepantasnya memiliki nilai tinggi bagi keberlanjutan kehidupan umat manusia di atas planet bumi yang sangat rapuh ini. Keanekaragaman hayati adalah  satu-satunya sumber materi genetik yang diperlukan untuk menumbuhkembangkanbioteknologi. Keanekaragaman hayati dan sumber daya genetik yang terkandung di dalamnyadiyakini akan sangat penting dalam upaya manusia menyesuaikan diri dan mengantisipasi perubahan iklim global dan memastikan pencapaian target MDG. Sebagai negara dengan keanekaragaman hayati terbesar, Indonesia berpeluang sangat besar untuk memberikan kontribusi bagi kepentingan umat manusia tanpa kecuali. Melalui kemajuan ilmu biologi, khususnya di bidang biologi molekuler dan genetika molekuler, keanekaragman hayati dangenetik yang ada di dalamnya dapat terus dipelajari, dilestarikan, dan dimanfaatkan untuk berbagai kepentingan, baik pertanian (produksi benih yang adaptif terhadap perubahan iklim dan perubahan pola konsumsi), industri (bioekonomi/ekonomi hijau), kesehatan (produksi obat baru untuk mengatasi berbagai penyakit baru/new emerging deseases), dan lingkungan (meningkatkan kualitas lingkungan). Lembaga Ilmu Pengetahuan Indonesia (LIPI) telahmendirikan Pusat Penelitian Bioteknologi, 10 tahun sebelum dibentuknya Komite Bioteknologi Nasional. Melalui sejarah panjang, LIPI secara berkesinambungan terus melakukan kegiatan riset di bidang keanekaragaman hayati. Dengan komitmen penuh, LIPI berupaya merawat koleksi spesimen tumbuhan, hewan, dan mikroba di Herbarium Bogoriense, Museum Zoologicum Bogoriense, Koleksi Kultur Mikroba, dan Kebun Raya, termasuk 18 Kebun Raya baru yang didirikan di berbagai kota dan provinsi di seluruh Indonesia. Penelitian terhadap nilai  manfaat keanekaragaman hayati juga dilakukan. Penelitian molekuler dan genetik merupakan salah satu di antaranya. Beberapa telah menunjukkan hasil yang positif. Kerja sama ilmiah internasional menjadi salah satu hal yang harus dilakukan dalam mempercepat pemahaman tentang arti pentingnya keanekaragaman hayati dan genetik yang ada di dalamnya serta mencari mekanisme pemanfaatannya yang tepat sesuai dengan kesepakatan internasional(CBD, Protokol Cartagena, dan Protokol Nagoya) sebelum sumber daya alam hayati ini mengalami kepunahan.

Communication pattern is different in its implementation for the Management of Research and Development units derived from background research rather than researchers. Circulation of information from communications to the above, tend to be undertaken by a leader who belongs to the researchers. In contrast information from the communication down, tend to be undertaken by the leadership that does not come from a background of researchers. Emergence the different communication patterns among others, is also influenced by the encouragement of informal communications that are not structured and not fixed by the habits of the leadership itself. Communication processes are carried out continuously and continuous between leaders and researchers in reducing the differences will lead to convergence of communication that can form a patterned process of communication.

Stream Water Temperature Studies at Forested Watersheds : a Review Subehi, Luki Suhu air Aliran sungai Daeah aliran sungai DAS Temperatur air sungai yang berpengaruh terhadap proses biologi, kimia, dan fisika yang terjadi di dalam ekosistem sungai telah menjadi perhatian utama dari sejumlah kegiatan para peneliti. Dianalisis secara statistik menggunakan root mean square (Rms), harmonik metode (A: Amplitude, φ: waktu tunda) dan perubahan dari spesifik debit (ΔQs), temperatur udara (ΔTa) dan temperatur air (ΔTw) selama periode hujan telah dilakukan dalam penelitian ini. Berdasarkan nilai-nilai fluktuasi, kita bisa mengklasifikasikan daerah aliran sungai menjadi tiga kelompok luasan DAS: kecil, menengah, dan besar. Di daerah aliran sungai besar, nilai fluktuasi Tw dijelaskan sebagai pengaruh radiasi matahari dan proses perpindahan panas, sedangkan daerah aliran sungai kecil, menunjukkan waktu yang lebih pendek bagi pola aliran yang mempengaruhi Tw. Selanjutnya, hasil analisis menunjukkan pola aliran yang berbeda, digambarkan oleh karakteristik loop histeresis antara Qs dan Tw di DAS menengah selama periode hujan. Perbedaan-perbedaan dalam loop histeresis dapat dijelaskan sebagai perbedaan Tw dan kecepatan respons terhadap curah hujan antara aliran permukaan/aliran bawah permukaan dan aliran air tanah.

IDENTIFIKASI KARAKTER TOLERANSI CEKAMAN KEKERINGAN BERDASARKAN RESPONS PERTUMBUHAN DAN HASIL GENOTIPE JAGUNG Efendi, Roy Evapotranspiration Drought stress Maize Roots Water use Genotypes The objectives of this experiment were to study (a) response of maize genotypes drought stress during anthesis up to grain filling or maturity stages and (b) determine characters as drought tolerance indicators. Factorial randomize complete block design this experiment was used with two factors. The first factor was drought tolerance and sensitive genotypes and the second factor was periods of drought stress consisted of three condition: (i) drought at anthesis up to grain filling stages, (ii) drought at anthesis up to maturity stages, and (iii) optimum condition.The results of research showed that tolerance genotypes had the abilities to maintain shoot growth (plant height and shoot dry weight) and suppress leaf damage under drought condition. The abilities of drought tolerant were supported by heavy root dry weight while resulted the extend of root absorbing more water. The ability of maize genotypes in keeping shoot growth, suppressing transpiration due to lower leaf stomata density and higher water use efficiency is an important factors in suppressing yield loss in drought condition. The sensitive genotypes wasnot had these abilities since it had low root dry weight, therefore, the root extension was not supported for absorbing adequate amount of water for shoot growth (shoot dry weight and plant height) and increasing the intensityof damage leaf under drought condition was high. Besides, the sensitive genotype had higher leaf stomata density and lower level of water use efficiency which caused the increasing yield decrease (grain wieght/plant) compare to tolerance genotypes, more over, in longer drought period of theirs genotypes were not filled.

VARIABILITAS MUSIM HUJAN DI KABUPATEN INDRAMAYU Setyawan, Fierra Rainy season Standardized Precipitation Index Indramayu Kabupaten Indramayu District is located in northern part of West Java. It has two seasons, dry season and rainy season. In this research, wet and dry rainy season in Indramayu District was investigated by using Standardized Precipitation Index (SPI). And also by using wavelet power spectrum analysis was investigated some factors that influence rainy season in this area. It is found that monsoon circulation is a dominant circulation that causing dry season (March – November) and rainy season (December–February). In extreme condition, El Niño – Southern Oscillation (ENSO) contributes to variability of rainy season. Index Southern Oscillation (SOI) influences variability of rainy season. If negative SOI occurred, mostly part Indramayu District has drier rainy season and the opposite, the rainy season will be wetter if positive SOI occurred. Another phenomenon that influences to the variability of rainy season is Indian Ocean Dipole (Dipole Mode Index, DMI). Negative DMI brings more precipitation. On the other hand, positive DMI influences to less precipitation.

PENGGUNAAN EGM2008, EGM1996 DAN GPS-LEVELING UNTUK TINGGI UNDULASI GEOID DI SULAWESI Ramdani, Dadan Geoids EGM2008 GPS GPS is used increasingly and commonly in the last past year in all aspect of live. But the height information in GPS is not the actual height. To convert it to actual height is needed geoid undulation. Geoid has three wavelengthsi.e. short, medium and long. From these three geoids, the long wavelength which is obtained from the global model is the important one to determinant the geoid. In 2008 Pavlis NK from NGA had established the global model (EGM2008) which has orde and degree of 2190. This global model was validated and is used to calculate the geoid undulation in Sulawesi. EGM2008 Validation was carried out with comparation between the geoid undulation of EGM2008 and EGM1996 with the geoid undulation from GPS-Leveling’s observation data. The result of this validation shows that EGM2008 in Sulawesi has better results compare with EGM1996. The standard deviation of EGM2008 is 0.88 cm better than EGM1996.

Karakterisasi Korosi Baja SS-430 pada lingkungan NaCL Jodi, Heri Corrosion Stainless Steel 430 Sodium Chloride X-Ray Diffraction Potentiostate SS-430 is a ferrite type alloy that can be selected for the base material of sea-water duct-pipes in the water supply system of a power reactor, but in general the ferritic alloy is not as good as austenitic with respect to corrosion resistance. Then NaCl environment is used to examine corrosion rate of SS-430. The corrosion was observed in four concentrations of NaCl solution. The experiments were carried out using M-273 EG&G potentiostate test instrument with polarization methode. The microstructure of post-corrosion samples were analyzed with an EDS attached to SEM instrument to detect the presence of any viable corrosion byproducts. X-ray diffraction methode was also used to detect any possible emerging corrosion on samples surfaces. The results showed that SS-430 suffers very little corrosion in NaCl environment, and that this material turn out to have an outstanding resistance toward NaCl corrosion.

TRANSLATION APPROACH OF ENGLISH METAPHORS INTO INDONESIAN (A CROSS CULTURAL UNDERSTANDING STUDY) Mulyanah, Ade Closed similes Open similes Dead metaphors Live metaphors This descriptive qualitative research aims at classifying important aspects related to sociolinguistics in rendering English metaphors into Indonesian. The study touches on several aspects dealing cross cultural understanding in translating metaphors taken from novel, TV serial, text bookin 2008. The cultural aspect in metaphors is related to important aspect of metaphors, namely, point of similarity, image, and figurative language. There are four types of metaphors in the paper: closed similes, open similes, live metaphors, and dead metaphors. The research reveals that: (1) Translation of closed similes can be rendered by applying literal translation meaning the focus of translation is on linguistics point of view. Translating direct metaphors (similes) is easier to transferthan indirect comparison (‘live’ and ‘dead’ metaphors). Transferring open similes needs the knowledge of the source and target language culture due to the absence of the point of similarity in the sentence. While, translating “dead” metaphors can be more understandable than ‘live’ metaphors by considering topic, image, and figurative language in both languages. (2) The paper is also trying to perform the difficulties in rendering English metaphors into Indonesian occur due to lack of standard Indonesian equivalent.

Indonesia participation in AFTA is worth noting since CEPT covers significant amount of Indonesian exports and imports. This paper investigates Indonesia trade performances under AFTA employing intra-industry trade analysis. It uses three digit SITC derived from UN COMTRADE. The results show that during 1992–2010, Indonesia and ASEAN trade was highlighted by intra rather than inter-industry trade, particularly for manufacture commodity. Further inter-temporal analysis confirms this finding with increasing trend of intra-industry trade for non-manufactured commodity. Nonetheless, Indonesian sectoral performance was less competitive compare to other ASEAN countries. This study suggests that Indonesia may enhance the advantage of being AFTA’s member by, for example, creating a conducive investment environment.

SEXUALITY IN PRISON: A STUDY ON PRISONER’S BIOLOGICAL NEED FROM A HUMAN RIGHTS PERSPECTIVE Citrawan, Harison Sexual need Prisoners Human rights Prisoner’s sexual need has been long a major discourse in Indonesia’s national correctional system. Up to this day, such a need is yet to be ruled under any legislative products. It is fully undoubted that the absence of legal protection upon prisoner’s sexual need may cause several negative impacts, such as sexual harassment, emotional instability, and to a certain extent family brake-ups. This research aims to discern the contstruction of prisoner’s sexual need as a right from a human rights perspective, and attempts to construe a proportional mechanism in fulfilling the right. The author used qualitative approach by interviewing prisoners, corrections officers, and other related parties, in two different locations. In conclusion, this research wraps two important points, first, sexual need as a right finds its justification derived from right to privacy and family life, right to humane treatment, and right to health and proper living. Second, there is a need for the state to arrange a mechanism in fulfiling prisoner’s sexual need based on human rights norms consideration.

METODE PEMBUKTIAN KESAHIHAN HADIS Usman, Usman Hadits Sanad Matan Rawi Prophet Everyone who will convey Tradition of The Prophet (hadits) must check his integrity so that not everybody can convey hadits. Appearance fake haditses push hadits experts to specify a method for proving hadits authenticity, by checking sanad (the transmission of hadits) and matan (text of hadits). Sanad and matan are two fundamental elements on every Hadits. There is a very tightly bearing that cannot be disassociated between sanad and matan. One  saying can be called as Hadits, if founded the existence of transmission of rawi (transmitterr) which waschronically up to the first source (Prophet Muhamad). On the contrary, the network of carriers, though to Prophet, without existence of message (text) which informed can not be called as Hadits. Existence of method for proving hadits authenticity is expected to become reference for everyone wishing to convey hadits correctly.

AKTINOMISETES KHITINOLITIK DAN PROTEOLITIK SEBAGAI AGEN PENGENDALIAN HAYATI NEMATODA SISTA KUNING (Globodera rostochiensis) Joko Nugroho, Agustinus Actinomycetes Chitinolytic Proteolytic Globodera rostochiensis Biocontrol Golden cyst nematode (GCN/Globodera rostochiensis) is a new potato parasitic nematodes found in Indonesia in 2003 and caused great economic losses more than 70% of the production. Due to the problem caused by chemically control (resistancy, killed non target organisms, and environment pollution) development of alternative control measures is a great importance i.g. microbial control. The purpose of this research was to find chitinolytic and proteolytic actinomycetes for controling eggshell nematode which bears vitelin (protein) and chitin. The result found 21 actinomycetes isolates with ratio chitinolytic and proteolytic activities more than 3.0 and among of seven isolates were chitinolytic, 11 isolates were proteolytic and three isolates had double enzyme activities. Seven selected isolates were examined on their chitinase and protease specific activities and ability to degrade nematode eggs. The results showed three isolates had chitinase activity more than 200 IU/mg, four isolates had protease activity more than 300 IU/mg. Results of the bioassay test using crude enzyme on the GCN eggs found that three isolates were able to damage eggs more than 90%. The three isolates can be applied as an agent for biocontrol of GCN in the future.

STUDI KOMPARATIF RESISTENSI ANTARA SAPI BALI DAN MADURA TERHADAP INFEKSI Fasciola gigantica Wiedosari, Ening Fasciola gigantica Resistance Bali cattle Madura cattle Designing of future approaches for the control of Fasciola gigantica infection in cattle requires an understanding of the host-parasite relationships. This study was therefore undertaken to compare the susceptibility to infection with F. gigantica between Bali and Madura cattle. Seven Bali and seven Madura cattle were infected orally with 15 metacercariae of F. gigantica twice weekly for 32 weeks. Similar observations were made on four Bali and 4 Madura cattle maintained fluke-free as controls. The study shows that there was a trend of a lower fluke burden and faecal egg counts Madura cattle than in Bali cattle. The packed cell volume (PCV) values was significantlyhigher in infected Madura than in Bali cattle (P<0,05). The increased of eosinophil cell response and the antibody isotypes imunoglobulin (Ig)G1 in Madura cattle were significantly higher than in Bali cattle (P<0,05). These varying responses represent differences in host-parasite relationships between Bali and Madura cattle and may be linked to the observed varying levels of resistance to F. gigantica infection between these host.

ANALISIS MORFOTEKTONIK SESAR LEMBANG, JAWA BARAT Hidayat, Edi Lembang Fault Morphotectonic Sagpond Active fault Normal fault The Lembang fault was located approximately 10 km to the north of Bandung City that crossed the Kecamatan Lembang City directe in east-west direction for 22 km length. The existence of this fault became very important because this fault crossed the densely-populated settlement and tourism area. Up to now, the level of the activity of this fault was still in matter of debate due to the insufficient of seismicity data and history resulted by the activation of this fault. One of the approaches to determine the level of the activity of the Lembang Fault is morphometry analysis. Paramater used to morphometry analysis comprise of ratio of valley floor width to valley height (Vf) and drainage basin asymmetry (AF). In addition to morphometry, sediment analysis sagpond also used to determine the fault activity. Result analysis of the two methods above, indicates that the Lembang an active fault with the movement down (normal fault).

PEREKAM/PEMUTAR SUARA DIGITAL BERKAPASITAS BESAR UNTUK APLIKASI EMBEDDED SYSTEM Yoppy Djuriatno, Waru Suprapto WAV file FAT16 file system SD card Voice recorder In embedded-system designs that involve just a small capacity voice-recorder, one may use EEPROM or voice-recorder IC. However, sometimes one needs a high capacity voice recorder also. In this case, EEPROM can’tfulfill the needs anymore because it’s hard to get EEPROM with capacity even at 512 kbyte. Meanwhile, the ISD® voice-recorder IC could store voice up to 16 minutes only. For this background, the writer proposes a high-capacity digital voice recorder which is able to record voice for several hours. It uses SD Card as the storage media.. With sampling rate at 8 kHz/8 bit and 512 MB SD Card, the recorder can store voice until 18 hours. The recorded voices are stored in WAV file format so that can be transfered from and to PC when neededWAV file BRIN Publisihing 2010-08-30 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://ejournal.brin.go.id/widyariset/article/view/16438 10.14203/widyariset.13.2.2010.99-106 Widyariset; Vol. 13 No. 2 (2010): Widyariset; 99-106 2461-0976 eng https://ejournal.brin.go.id/widyariset/article/view/16438/12582 Copyright (c) 2010 Author(s)

EVALUASI METODE PENAJAMAN CITRA MULTISPEKTRAL DENGAN MEMANFAATKAN KANAL PANKROMATIK Dianovita Remote Sensing IHS-RGB PCA Brovey SPOT-4 Image Pansharpened This paper studied three methods of pan-sharpenning of SPOT-4 image and evaluated the quality of the results. Three pan-sharpenning methods were applied to a scene of SPOT-4 image of K/J:287/364 acquiried on 25 July 2008 by using image processing software. Those three methods were IHS-RGB, Color Normalized (Brovey), and PCA (Principle Component Analysis). For IHS-RGB and Color Normalized (Brovey) methods the formulas written in Kartasasmita were used. These formula are practical to be used in image processing software and canbe understood theoritically. Similarly for PCA (Principle Component Analysis) method on this research the values of the elements of eigenvectors, which are required for doing the transformation and inversion, are calculated before then they are used in a new more practical equation and can be inputted to image processing software. It was expected that three mathematic equations from those three methods can be implemented easily in other image processing softwares and used for other multispectral image sharpenning by panchromatic band. An assessment to test the pan-sharpenning processes quantitatively and qualitatively were conducted. A qualitative assessment had been conducted by visual interpretation of pansharpened image. Quantitative assessments of pan-sharpened image was showed by change of spectral value range of each spectral channel, measureof the slope detail of pansharpened image from several object detail and the spectral information similarity between original and pansharpened images by Q Index and Correlation Coefficient. The results of this study are practical equations for PCA, IHS-RGB and Color Normalized (Brovey) Methods; pan-sharpened of SPOT-4 image; and quality assessment of pan-sharpened of SPOT-4 image.

PENGARUH PENAMBAHAN POLISTIRENA TERHADAP SIFAT MEMBRAN SELULOSA ASETAT BERBAHAN DASAR LIMBAH TAHU Rachmadetin, Jaka Composite membrane cellulose acetate bacterial cellulose Soybean curd whey, which is discarded as a waste, can be used as starting material for the preparation of cellulose and cellulose acetate membrane. However, due to its poor mechanical properties, blending with polystyrene will strengthen to the membrane. Nata de soya was made by soybean curd whey then was dried to produce cellulose flake. Cellulose flake was reacted with acetylation reagent, acetic anhydride, and other solvents to produce cellulose acetat flake. It was then mixed with polystyrene to form blend of cellulose acetate:polysyrene membrane with 100:0, 95:5, 90:10, 85:15, and 80:20 in ratios. These membranes were characterized by water flux, rejection index, and tensile strength. The results showed that cellulose acetate had produced a water content of 4.3%, and acetyl degree of 43.26% (equal to substitution degree of 2.8-3.0). The highest water flux membrane was made of 80:20 (164.23 l/m2., the highest rejection index was from 90:10 was 31.65%, and the highest tensile strength membrane was obtained from 80:20 (24.11 kgf). In conclusion the addition of polystyrene could increase the water flux and tensile strength of membrane, but it decrease the rejection index.

EFFECTIVENESS OF CYROMAZINE APPLICATION AND PARASITOIDS RELEASE FOR CONTROLLING AGAINST LEAFMINER FLY Liriomyza huidobrensis (BLANCHARD) (DIPTERA: AGROMYZIDAE) Tantowijoyo, Warsito Liriomyza huidobrensis Cyromazine Parasitoid Liriomyza huidobrensis is an invasive pest for various crops. Till now, the management of this pest is by the only use of pesticides which hence increased its resistance and decrease of its natural enemies. The objective of the study was to assess the effectiveness of cyromazine and parasitoids for reducing the population of leafminer fl y (L. huidobrensis) and to analyse the economic impact of the different treatments. The study was conducted in the Sirukem village, Kalibening sub district, Banjarnegara district, Central Java from July to November 2009. To address the objective, four treatment strategies were applied: no treatment, cyromazine, parasitoid release and cyromazine-parasitoid, and observa-tion of damage intensity, sampling of infested leaves, assessment of yield and an economic analysis were undertaken. The results found that cyromazine and parasitoids were effective to control against infestation of Liriomyza. Cyromazine was also harmless for parasitoids. The dominant parasitoid found were Opius chromatomyiae and Hemiptarsenus varicorni which preferred to parasitize the larvae of L.huidobrensis on Vicia faba than on Solanum tuberosum.

The effect of climate anomaly on rubber plantation is very influential on rubber production. This research aims as analysis of La-Nina 2010 effects on experiment field Sembawa Research Centre. This research was carried out in experiment field Sembawa Research Centre at 2011. Research was conducted by analyzing the impact of rainfall in 2009 and 2010 on the availability of seed, reduction of tapping days, and rubber crop productivity. The results showed that the presence of La-Nina climate anomalies resulted in the availability of seed decreased by 50% for rootstock breeding. In addition, rubber production in the clones are susceptible to Colletotrichum leaf fall disease is reduced. Furthermore, tapping days were reduced 9 days because of the high intensity of rainfall. On the contrary, La-Nina caused a time delay of leaf fall sesion, so it did not give negative impact on productivity of Experiment Field Sembawa Research Centre. Attempts to reduce the impact of La-Nina climate anomalies have been done by planting specific location rubber clones, using rain guard technology, and giving extra fertilizer on the plants which are suffered by leaf fall disease.

IDENTIFICATION OF SEDIMENT PROPERTIES DEGRADATION OF DELTA CIMANUK DEPOSIT BASED ON STRATA BOX DATA Rahardiawan, Riza Sediment Properties Cimanuk Delta Strata Box Knowledge on physical properties of seafloor sediments is essential in planning offshore construction, in particular oil and gas construction. Changes in the physical properties of sediments such as faults and fractures, as well as the presence of gas within seafloor sediments can be detected as a decrease in acoustic wave velocity due to reduction in sediment shear strength. Normalization of Cimanuk River in early 1980s has resulted in higher sediment influx and increasing rate of compaction that change the physical properties of the sediment. Analysis of amplitude and wave velocity using software SonarWiz 5 on the records obtained from sounding equipment: Sub-Bottom Profiler type ODEC Strata Box and Bathy 1500, show significant change in wave speed that is caused by shallow gas seepage associated with fractures in the Polygonal Fault System (PFS ). This fault system formed as a result of diagenetic processes of fine grain sediment and reduction of the sediment shear strength due to accumulated sediment cover. Shallow gas seepage itself is commonly found in organic-rich marine sediments and are usually composed of methane.

ACETIC ACID FORMATION STUDY IN COCOA SWEATINGS TREATMENT UNDER ANAEROBIC CONDITION Billqys Nurhayati Prativi, Mahensa cacao pulp flushing acidogenesis acetic acid oxygen This research aimed to study the possibility of cacao sweatings treatment to produce intermediate compound i.e. acetic acid in acidogenesis processes. It were carried on an anaerobic Circulating Bed Reactor which is made from flexyglass 6 L capacities and operated in batch system. The operation of two circulating bed reactor conducted at room temperature for 20 days and nitrogen gas flushing is performed at one of the reactor for 10 minutes in the beginning of operation. Gas composition analysis indicates the persistence of O2 in reactor A, hence the acetic acid formation follows the aerobic pathway and occurs more rapidly. Concentration of O2 in reactor B is relatively low compared to reactor A. So that is concluded that acetic acid formation reach the anaerobic pathway and run slowly. This research indicates that the presence of O2 in the reactor affect the pathway of acetic acid formation.

THROUGH ENDOSPERM CULTURE IN VITRO Agus, Lazarus Endosperm n vitro cultured Triploidy Sandalwood Santalum album Sandalwood (Santalum album L.) is an over exploitation that causes the population decreases drastically. An experiment was carried out to get triploid plant by using young seed culture. Young seeds of sandalwood were peeled and grew on solid Murashige and Skoog (MS) media formulation with or without addition hormones of α-napthaleneacetic acid (NAA), 2,4 dichlorophenoxyacetic acid (2,4-D), 6-benzylaminopurine (BA) or kinetin.(K). The young seed did not form shoot, but its endosperm formed callus. The endosperm produced callus 26.67%on media with addition of BA 1 mg/l, but not on media without any addition of hormone. The best callus production was on media with addition of NAA 2 mg/l and BA 1 mg/l. The best somatic embryos formation was NAA 1 mg/l + BA 1 mg/l and shoot formation was 2,4-D 1 mg/l + K 1 mg/l treatments. The resulted shoots from endosperms are expected to be triploid plants.

PERAN PENYIDIK PEGAWAI NEGERI SIPIL (PPNS) PERIKANAN DALAM PROSES PENEGAKAN HUKUM KASUS IUU FISHING DI INDONESIA Yulia Arthatiani, Freshty Illegal fishing PPNS Law This study aimed at describing the role of Fisheries Civil Servant Investigators (PPNS) in the law process of Illegal, Unreported and Unregulated (IUU) fishing in Indonesia. It utilized a descriptive qualitative method to analyse the primary and secondary data, which had been collected through interviews, observations and FGDs from a purposively chosen sample with a juridis normative approach. Definitively, IUU fishing is the act of fishing within the Indonesian, other country’s jurisdiction, or the open waters without permit, not reported, and not regu- lated. The law No. 45 year 2009 concerning the amendment of Law No. 31 Year 2004 on Fisheries stated that there are three sorts of law enforcers who have the rights to conduct investigations on offense in the fisheries sectors: the Civil Servant Investigators, the Navy Investigating Officers and the National Police Investigators. Despite the fact that the Civil Servant Investigators have been playing an active role in the law enforcement, especially for the IUU fishing cases, the function has not yet been very effective due to the lack of inter-institution coordination as well as communication among the law enforcers. Hence, matching perception, investigation mechanism as well as enforcement among the law enforcers are of utmost importance to alleviate the effectiveness of combat against IUU Fishing in Indonesia.

NILAI KESETARAAN LAHAN BUDI DAYA TUMPANG SARI TANAMAN TEBU DENGAN KEDELAI: STUDI KASUS DI DESA KARANGHARJO, KECAMATAN SULANG, KABUPATEN REMBANG Rifai, Ahmad LER Intercropping Sugarcane Soybean Self-sufficiency of soybeans and sugar is one of main targets of  the Ministry of Agriculture’s strategic plan in 2014. This government’s target may not be achieved due to the lack of land for cultivation. This research aims to analyze the efficiency of land use by using monoculture and intercropping methods for growing sugarcane and soybean. The results of experiment studies showed that the Land Equivalent Ratio (LER) between sugarcane and soybean has a value greater than 1in overall, indicating that the intercropping pattern is more efficient and productive than the monocultures cropping. The highest LER is VMC76-16+Kaba varieties intercropped, which is 2.21, while the lowest LER is intercropped PSJK922+Argomulyo, which is 1.41. Based on financial analysis, the highest NPV is Rp126,852,727,00, the B/C ratio is 2.56 for intercropping of VMC 76-16 + Argomulyo. Based on these results, the area of 64501.99 ha sugarcane in Central Java can potentially increase the soybean area 32250.995 ha and its production  56,700 tons per year.

PENGGUNAAN ARBITRAGE PRICING THEORY DALAM MENGUKUR RETURN KELOMPOK SAHAM SEKTORAL Widya Anantayoga, I Gede Arbitrage pricing theory Return Sectoral indices There are some approaches that can be done to quantify the risk for investors in order to produce maximum yields and one of the models used is the Arbitrage Pricing Theory (APT). APT is considered more flexible than the Capital Asset Pricing Model (CAPM) because the model can use a variety of various macroeconomic factors in calculating the risk premium of an asset or to establish a model of asset valuation. Macroeconomic factors of an established model can change over time so does the risk premium contained. The purpose of this study is to do analysis using APT whether macroeconomic variables (oil prices, the exchange rate of IDR against the USD, and the rate of inflation) are factors that affected stock returns in sectoral index in Indonesia. This study uses the time span from January 2007 to December 2012 with the object of study is 9 different sectors in sectoral stocks indice, whereas the method used is multiple linear regression. This study concludes that among the three macroeconomic factor that are used as research material (crude oil prices, the exchange rate of the rupiah against the U.S. dollar, and inflation), the dollar exchange rate is the most significant factors in measuring the sensitivity of return of sectoral stocks indice.

Kecamatan Majalaya is chosen as locus of this re- search because of its uniquenesses. One of its uniquenesses is a diversity of communities that have experienced acculturation and language. The data examined in this study amounted to one hundred and seven vocabularies. The method used in this study is descriptive, i.e. a method that aims to create a portrait or depiction on data, at- tribute, and relationships of phenomena under study in a systematic, factual, and accurate way. Thus, the expected result is to establish the description of vocabulary in form of a portrait or disclosure as it is. The purpose of this study is to identify the development of the vocabularies in Bandung’s geographical dialect, that is the frontier of lulugu Sundanese (formal language) and Bandung Sundanese (informal language). The results showed that there was a wide difference between Majalaya northern dialect with South Majalaya in phonologic-morphophonemic, such as language symptoms of metathesis, protesis, epentesis, aperesis, syncope, and apocope. Beside that, there are morphological differences in repeated words (reduplication) and compound (compositum), while in semantical differences, there may be a completely different form, but the inherent meaning is still the same.

ANALISIS PENGARUH RASIO KEUANGAN TERHADAP PROBABILITAS KEBANGKRUTAN EMPAT BANK DALAM KELOMPOK LG 45 DI BURSA EFEK INDONESIA Agus, Sekartiga KMV Merton model Default probability The bank’s financial ratio Multiple regression analysis of panel data Eviews 6.0 Bank is an entity that acts as a financial intermediary that puts the public funds entrusted to it, to be dis- tributed back to the community in form of loans, and the business world at large in form of credit. Outstanding funds through banks can be optimized to support the investment, which in turn encourages economic growth, and improves standards of living and equitable development. Therefore, the banking operations should be monitored closely by the stakeholders. The purpose of this study was to analyze the probability of bankruptcy of the banking sector and to analyze the relationship between accounting information in form of financial ratios (APB, ROA, ROA, ROE, LDR, NPL, ATTM, CAR, and NIM) to the probability of default (PD) by using KMV Merton. The object of this study is banks that are consistent listed in LQ 45 period 2009–2012 and issuing bond. The research result showed that the probability of bank failure from KMV Merton models give an indication of low level of bank failures with the highest rating of AAA, so PT Bank Rakyat Indonesia Tbk., PT Bank Mandiri Tbk, PT Danamon Indonesia Tbk., and PT BPD of West Java and Banten Tbk. are worth to be invested. The regression analysis of financial ratios can explain 88.44% in PD equation model. Based on the regression analysis performed, the independent variables in the regression have a significant effect on the dependent variable of the banks listed in LQ-45, which is the Operating Expenses to Operating Income (ROA) has a positive influence on PD and Against Capital Fixed Assets (ATTM ) has a negative effect on PD.

MICROHABITATS OF Hylarana chalconota ALONG FAST FLOWING WATER STREAMS IN DEGRADED LAND IN GUNUNG SALAK FOOT HILL Kurniati, Hellen Sumadijaya, Alex Hylarana chalconota degraded land Gunung Salak This research was conducted to determine the microhabitat selection in the frog species Hylarana chalco-nota in fl owing aquatic habitats situated in degraded land. Three survey sites (river, ditch, pine plantation) were selected in the Curug Nangka area on the slopes of Gunung Salak at an altitude between 630–740 m above sea level. Transect methodology was used to determine the microhabitat preference in H. chalconota. Two ways pairedand one-way ANOVA were used to test the impact of environmental factors on the microhabitat preference of H. chalconota. A signifi cant effect of air humidity on the presence of individual frog in the river and pine plantations was observed, but other environmental factors (air temperature, water temperature, air humidity, moon phase) had no signifi cant effect on individual H. chalconota along the ditch irrigation. In selecting microhabitats, the frog prefers vegetation below the substrate. However, frogs did not select specifi c plant species;preference appears to be related to the nature of the leaf and petiole strength. In horizontal microhabitat selection, individual frog tend to choose a distance between 0-1 meters from the edge of a river or ditch, while in vertical microhabitat selection, individual H. chalconota tend to choose a distance between 0–1 m from the ground.

FORMULA OPTIMIZATION OF PLANTAGO (PLANTAGO MAJOR L.) HERB EXTRACT CHEWABLE TABLETS AT VARIOUS MANITOL- LACTOSE RATIO USING SIMPLEX LATTICE DESIGN Nur Hayati TN., Septi Saifullah S., TN. Mulyani, Sri plantago herb decoction simplex lattice design chewable tablets The use of plantago (Plantago major L.) traditionally is less practical, therefore it needs to be developed into chewable tablet dosage form which is more acceptable. To prepare chewable tablet, lactose as a fi ller was used to substitute a part of mannitol which is relatively more expensive. Simplex lattice design (SLD) method was used to obtain the optimum ratio of mannitol-lactose mixture. Formula optimization using SLD was determined by testing of the granules physical properties: fl ow properties, compactibilities, and absorption capacities of water at various ratio. Plantago herbs were extracted by decoction and characterized. Granules of optimum formula were compressed into tablets and followed by testing its qualities: weight uniformities, hardness, brittleness, and qualitative analysis of chemical compounds using thin layer chromatography. Physical properties data of granules and chewable tablets were analysed using theoretical method and statistical with T test. The results showed that the increase of lactose proportion increased the fl ow properties, compactibilities, and absorption capacities ofwater. T-test at 95% confi dence level (α=0.05) indicated that SLD equalization was valid. Optimum area located between lactose-mannitol 100% : 0% and 20% : 80% with optimum formula was lactose-mannitol 100% : 0% as an optimum formula.

PERFORMANCE EVALUATION OF SPRAY COLUMN FOR TOLUENE REMOVAL AS A TAR MODEL FROM A GAS FLOW Suharto K L a value Spray column Used cooking oil Gasifi cation has become an alternative technology to convert biomass as renewable energy resource. How-ever, the utilization of gas from the process as diesel-engine fuel is hindered by the presence of tar. Used cooking oil could be used as tar absorbent medium due to its higher or nearly equal boiling point compared with that of tar component. In this study, the performance of spray column was evaluated by measuring the absorption effi ciency and mass transfer coeffi cient of volumetric tar in liquid phase (KLa). The tar used in this study was represented by toluene which was carried by air fl ow and then set as tar model in gas producer. The tar model dispersed in air was injected to spray column for absorption process with gas fl ow rate 2.580 L/min and temperature 30°C. The composition of tar model in gas phase was determined both as input and output of spray column by gas chromatography fl ame ionization detector (GC-FID). The absorption effi ciencies of toluene with absorption liquid of water, 5.4% w/w used cooking oil in water and 10.8% w/w used cooking oil in water are 70.2%, 93.8% and 95.2% respectively in 30°C, with KLa value 1.59.10-2/min, 7.10-4/min and 4.10-4/min respectively.

RESISTENSI PLASMA NUTFAH IRRDB 1981 TERHADAP PENYAKIT GUGUR DAUN Corynespora Putri Juliantika Kusdiana, Alchemi Rubber plants IRRDB 1981 Germplasm Corynespora casiicola Leaf fall disease caused by Corynespora casiicola can damage the rubber resulting in considerable economic losses. The opportunities to get rubber plant genetic resources that are resistant to leaf fall disease Corynespora casiicola have been made   by testing the resistance of some germplasm IRRDB 1981. Testing the resistances of some germplasm is to produce genetic resources that are resistant to leaf fall diseases and used as parents in the crossing. Testing was done by using immersion leaves method in a solution of toxin C. casiicola. Resistance testing of 28 genotypes germplasm IRRDB 1981 showed various resistance responses. The results indicated that there were five genotypes that had moderate resistant which were PN 323, PN 333, PN 448, PN 494, and PN 593, and one genotype PN 235 showed highly resistant. The six genotypes needed to be tested in the field to determine their interaction with the environment and then used as cross parents to obtain resistant parentage to C. casiicola leaf fall disease.

NISBAH HARA MIKRO TERHADAP KALIUM DAUN BEBERAPA VARIETAS PADI (Oryza sativa L.) PADA DUA JENIS TANAH Yustisia, Yustisia Fe/K Mn/K Cu/K Zn/K Growth Grain yield Rice Pot experiment was conducted at the experimental farm of Agriculture Faculty, Gadjah Mada University, Yogyakarta and aimed to investigate the effect of soil types, varieties and  and their interaction on Fe/K, Mn/K, Cu/K and Zn/K leaf, growth, leaf protein and grain yield of rice. The experiment was set up in a 2 x 6 factorial pat- tern randomized completely block design with three replications. First factor was two soil types viz. Vertisols and Inceptisols, second factor was rice varieties viz. Cimelati, Pandan Wangi, Ciherang, Cisokan, Widas and IR 64. The result revealed that the Fe/K, Cu/K and Zn/K ratios in rice leaf was significantly affected by soil types and rice varieties. The interaction of soil and rice varieties significantly affected the leaf ratios of Fe/K, Cu/K and Zn/K, crop growth rate (CGR) and grain yield, but it was not significantly affect the Mn/K ratio and leaf protein. The leaf ratios of Fe/K, Cu/K and Zn/K, CGR and grain yield in Vertisols were significantly higher than those in Inceptisols, while Mn/K ratio and leaf protein was significantly higher in Inceptisols. The highest of grain yield was achieved by Pandan Wangi whereas the lowest of grain yield was achieved by IR 64. The lowest of grain yield was achieved by IR 64 in Inceptisols. It was affected by an imbalance of Mn/K ratio and highest of leaf protein. It could be due to the effect of Inceptisols native soil properties (lower pH, higher Mn and K) and specific characteristics of IR 64 (more responsive to low pH, higher NH +  uptake). It was also may be caused by indirect effect of urea excess and KCl fertilizers on reducing of rhizosphere pH. The Mn/K ratio was important nutrient imbalance in Inceptisols soil and rice plant. The finding of this study suggests that the research in depth which is focused on Mn/K ratio balance in Inceptisols is needed, i.e using urea and KCl application in proper rate, using another source of nitrogen and potassium fertilizers, and using specific of varieties (less responsive to NH + and more responsive to NO -).

TEKNIK PENGEMASAN DALAM TRANSPORTASI UNTUK MEMPERTAHANKAN MUTU BUNGA POTONG ALPINIA (Alpinia purpurata) Marsetyowati, Tri Packaging Transportation Quality Alpinia purpurata PP plastic Oneway orientation of placement Alpinia purpurata flower is one type of cut flower with great opportunity as an exported flower for its attrac- tive shapes and colors. In order to gain maximum benefit from cut flowers as ornaments, post-harvest treatments require attention. One of those treatments is packing which aims to maintain the quality of cut flowers during transport or shipping. The objectives of this study were to determine the type of primary packaging material and the most suitable placement inside the packaging during transport in order to conserve the quality. Factorial Completely Randomized Design with 3 replications was used. To find out the effects of the treatments, analysis of variance was done using F-test. Difference among treatments was tested using LSD at 5% significance level. The results showed that the use of PP plastic as packaging material gave a significant difference on weight loss, flowers’ freshness during transport, freshness period during demonstration time and the amount of holding solution absorbed. Packaging technique with plastic as the packaging material gave the best result with longer freshness period (7.77 days), flowers had the lowest weight loss (0.71%), the flowers seemed quite fresh (score of 4) and were able to absorb more holding solution (4.81ml/stalk/day) during demonstration time and therefore they remained in fresh condition. One-way orientation of placement was the best treatment at weight loss (0.77%) and the amount of holding solution absorbed (5.04ml/stalk/day).

INFLUENCES OF METEOROLOGICAL PARAMETERS AND OZONE PRECURSORS TO NEURAL NETWORK MODEL IN OZONE TROPOSPHERIC CONCENTRATION (STUDY IN BANDUNG CITY) Lukita Sari, Dyah Driejana, R. Air Quality Artificial Neural Network Tropospheric Ozone As an air pollutant, the fate of ozone is determined by the movement and chemistry of atmospheric dynamics and the precursors of ozone are emitted from the source. In that case the effect of each of meteorological param- eters and ozone precursors need to be known so that the ozone concentration can be predicted. In this research the concentration of ozone precursors (NO and NO2), temperature, solar global radiation, humidity, and wind speed as meteorology parameters were used as input in artifi cial neural network program to obtain model which can predict concentration of tropospheric ozone in Bandung city. The relation between ozone precursors concentration and meteorological parameters to ozone concentration was indicated by the correlation value. Positive correlation values, the increase in ozone concentration, was infl uenced by variables of temperature and solar radiation. A negative correlation value, the decline in ozone concentration, is affected by humidity variables. Modelling results indicate that the use of temperature and concentrations NO2 as data input appeared to be a dominant contributors rather than the other input parameters.

PRODUKSI BIODIESEL DARI BIOMASSA Chlamydomonas sp. ICBB 9113 DIKULTIVASI MENGGUNAKAN MEDIA YANG MURAH: EFEKTIFITAS DARI BEBERAPA METODE EKSTRAKSI Patmawati, Patmawati Biodiesel Crude lipid Extraction Microalgae The main challenges to overcome in biodiesel production from microalgae are lower oil yield, as compared to those derived from plant and animal biomass, and expensive culture media. This work was aimed to compare the effectivity of three extraction methods differed in solvent used, e.g. n-hexane (N-hex), ethanol (Eth), and mixture of chloroform-methanol-water (CMW), to extract crude lipid and biodiesel from dry biomass of Chlamydomonas sp. ICBB 9113. This microalgae was cultivated in a cheap culture media using N and P soil fertilizers as nutrient sources. The results showed that, by using N-hex, Eth, and CMW methods, it could be extracted, respectively, 0.06%, 4.51%, and 20.45% crude lipid, and 384.2, 1333.8, and 2430.6 mg/100g biodiesel. The fatty acid profile of the studied microalgae biomass was: C8:0 (0.11%), C10:0 (0.09%), C14:0 (7.70%), 16:0 (1.39%), C18:0 (0.85%), C14:1 (5.12%), C16:1 (7.09%), C18:1 (8.28%), C18:2 (12.80%), and C18:3 (42.57%). Fatty acid characterization showed that Chlamydomonas sp. ICBB 9113 was dominated by C18: 3 and C16:0. Therefore, these microlagae were suitable to be used as raw material for biodiesel production to substitute the conventional fuel.

PENENTUAN MASA TANAM KEDELAI BERDASARKAN ANALISIS NERACA AIR DI KABUPATEN KONAWE SELATAN, SULAWESI TENGGARA Musyadik, Musyadik South Konawe Water balance Time planting of soybean South Konawe is a regency in Southeast Sulawesi which is dominated by dry land around 42,151 ha. Out of this area, only 2,100 ha was utilized for soybean planting with yield of 1.051 t/ha. One of problems for this low productivity is not optimal use of the technology in terms of usage time of planting. From the analysis of the water balance sheet, it shows that the surplus occurs in January, March, April, May, June, and July. However, soybean can only be planted in May because it meets the water requirement for soybean that is 250–300 mm/month. On the other hand, deficit months occur in February, August–December.

WING PLANFORM INFLUENCE ON FLIGHT CHARACTERISTIC OF ROCKET-LAUNCHED UNMANNED AIR-VEHICLE Nugroho, Larasmoyo Wing planform Flight Characteristic Rocket UAV Design of the wing planform depended on some geometry key factors such as aspect ratio, sweep angle, taper ratio, and angle of incidence. The search for optimum fl ight characteristic could be observed from aerody-namic coeffi cients, fl ight stability, fl ight dynamic, fl ight performance, and fl ight quality. To examine the design of the wing planform, this paper presented an experiment that modify few factors of wing geometry and simulated itconcerning the launching phase of the unmanned air-vehicle or UAV using rocket as booster. The optimal design of the wing is a prerequisite for the UAV to achieve its main mission as a national defense missile. Using X-Planev 8.6 as a fl ight simulation tool, the experimental results showed that a hybrid wing could produce an intermediate grade fl ight characteristic between rectangular wing and delta wing. Rectangular wing tended to produce a highlypitch-up trajectory when catapulted by a rocket booster, while delta wing produced a more stable pitch attitude and more better  fl ight performance. This experiment showed that hybrid wing was the appropriate choice forsubsonic jet UAV that had to be launched by rocket.

The results of such crossbreeding must be characterized and sorted to obtain new superior varieties that show the expected appearance of phenotype. The research aimed to get information about phenotypical appearance diversity and heritability value of some characters of some papaya hybrids. The study was conducted from March 2011 to February 2012 at the Sumani Research Station, Tropical Fruit Research Institute. The research was arranged in a randomized block design with six treatments and three replications. Each unit consisted of eight plants. The results showed that the phenotypical appearances such as fruit weight, fruit girth, fruit cavity width, and a larger number of perfect flowers, was influenced by genetic factors and had high heritability values. Genotypes  P 13, P 14, P 21, and P 31 could be the superior variety candidates because of their early maturity, low height of first flower and first fruit, i.e. < 1 m (low bearing), medium-sized fruit, thick fruit flesh and sweet taste, and PTT > 13° Brix. Some of papaya hybrids are expected to be new superior varieties of papaya Indonesian.

PREPARATION OF NI-MO CATALYSTS USING THE PILLARED CLAY AS A SUPPORT FOR HYDRODESULFURIZATION OF COKER NAPHTHA Rinaldi, Nino Preparation Ni-Mo pillared clay hydrodesulfurization Coker naphtha On the preparation of the Ni-Mo catalysts, a high of surface area of the support was needed in order to achieve the well dispersion of Mo on the support. One of the promising ways is the use of pillared clays as the support. Therefore, the preparation of pillared clay for a support of Ni-Mo catalyst and its effect on thehydrodesulfurization (HDS) reaction for sulfur removal of Coker naphtha were studied. The effects of pH of the Mo impregnation solutions were also studied. The results show that the pillarization process on clay using Al-pillared is signifi  cantly increased the surface area. Moreover, with the pH of the impregnation solution of 10, Mo is higher dispersed on the pillared clay support compared to pH-1, and thus the HDS activity of NiMo pillared clay catalyst of pH-10 is also more active. However, the HDS activity of the present catalysts is still not good enough compared to the commercial NiMo catalyst.

SIMULASI OPTIMASI PENGUKURAN STATE OF CHARGE BATERAI DENGAN INTEGRAL OBSERVER Nugroho, Asep Battery State of charge Integral observer State space Transfer function The accuracy of state of charge (SoC) measurement has been an important key in the design of Battery Management System (BMS). A SoC measurement can prevent the battery from both overcharged and undercharged condition. One of the conventional methods for SoC estimation is coloumb counting (CC). This method has a drawback regarding to the accumulation of error propagation. To improve the accuracy of CC method, the integral observer could be added. In our work charge-discharge data simulation generated by PSIM was used to test the Integral observer performance. This research used general lithium-ion battery. It was found that this approach could significantly correct the error from the numerical integral calculation and discrete data input. The error of CC method at 4000 sec was found to reach 25%; however the error propagation could be decreased up to less than <3% by Integral observer.

ALTERNATIF KAROTENOID SINTETIS (ASTAXANTIN) UNTUK MENINGKATKAN KUALITAS WARNA IKAN KOKI (Carassius auratus) Sukarman, Sukarman Goldfish Carotenoid Astaxanthin Marigold Carassius auratus Any deficiency of carotenoid in goldfish’ feeds can fade the color of the fish (Carassius auratus), especially in aquarium condition. The aim of this study was to explore other sources of carotenoid which is to replace the synthetic carotenoid already used. The fish were fed with different types of feed i.e. those without carotenoid source (A), those with synthetic astaxanthin (synthetic carotenoid) (B), Haematococcus pluvialis meal (C), and marigold petal meal (D). Lightness (L), chroma (C), hue (H), and the content of total carotenoids in the skin of fish were analyzed. The result showed that lightness was not significantly different among treatments. The best value of chroma was 35.59% (D), significantly different from those with other treatments and followed by 25.25% (B), 20.36% (C), and 19.98% (A). The highest content of total carotenoid in the skin was derived from B (59.55mg/kg), followed by D (24.79mg/kg), C (6.84mg/kg), and A (5.37mg/kg). This study suggests that marigold petal can be used as an alternative natural carotenoid source replacing synthetic carotenoid.

EKSPRESI HASIL GABAH DAN ANALISIS LINTASAN BEBERAPA VARIETAS UNGGUL BARU PADI DI SLEMAN Sutaryo, Bambang Grain yield Path analysis New varieties Rice Experiments to examine the expression of grain yield and path analysis of several new rice varieties were conductedat irrigated paddy fields, Godean, Sleman, Yogyakarta, during the wet season from November 2012 to March 2013. Five new varieties of rice namely Inpari 4, Inpari 7, Inpari 10, Inpari 11 and Inpari 19 and a popular variety Ciherang were used as checks. Fifteen-day old seedlings sown one seed per hill were planted by jajar legowo 4:1 method, with spacing between plants 25cm x 12.5cm x 50cm, in a 4m x 5m plot. The experiment was designed using a randomized block pattern with three replications. Data obtained indicated that the highest grain yield was obtained by Inpari 10 (9.3 t/ha), followed by Inpari 4, Inpari 7, Inpari 11 and Inpari 19 (9.0 ; 8.6; 8.4 , and 8.3 t /ha, respectively). Those five varieties above mentioned gave grain yield significantly higher than that of Ciherang (5.5 t/ha) and provided excess grain yield amounted to 69.1; 63.6; 56.4; 52.7; and 50.9% for Inpari 10, Inpari 4, Inpari 7, Inpari 11 and Inpari 19, respectively. Maturity varies from 117 days to 122 days for Inpari 4 to Inpari 11, while the lowest plant height was 103.2 cm for Ciherang and Inpari 4 was the highest at 116.2 cm. Path analysis showed that filled grain per panicle directly affected yield, and contributed indirectly to the correlation between yield and each yield components.

PENETAPAN NILAI ACUAN AMILOSA BEBERAPA VARIETAS PADI MENGGUNAKAN METODE PENGIKATAN IODIN (I): KALIUM IODIDA (KI) MELALUI UJI BANDING ANTARLABORATORIUM D. Ardhiyanti, Shinta Reference material Assigned value Amylose Rice The assigned value of amylose content in rice is the key factor in the development of internal laboratory quality control system. To produce reliable data, quality control system becomes necessary. The aim of this research was to determine the assigned value of amylose content of several rice varieties through interlaboratory testing. This research was conducted in 2012 in Post-Harvest Physiology Laboratory of Indonesian Center for Rice Research (ICRR) and several laboratories in Bogor, West Java, as interlaboratory testing participant. Samples used in this research were 4 new superior varieties with different amylose content i.e. Lusi, Sintanur, Ciherang, and Inpari 12, and had been confirmed for their homogenity and stability. The Cochran’s, the Grubbs’, and the Z-score tests were used to determine the outlier data of the interlaboratory testing results and the competent laboratories as well. The assigned values obtained for each variety were Lusi 6.29% (±1.73); Sintanur 19.42% (±1.51); Ciherang 23.78% (±1.44); and Inpari 12 29.83% (±0.68). All tested varieties could be used as reference materials in determining the laboratory performance to analyze rice’s amylose content using iodine: potassium iodide (I:KI) binding method.

POTENSI ANTIOKSIDAN DAN AKTIVITAS ANTIPROLIFERASI EKSTRAK KUNYIT PUTIH (Curcuma zedoaria Rosc.) PADA SEL HELA Saefudin, Saefudin Antioxidant Cytotoxic effect Antiproliferative activity Extracts Curcuma zedoaria The aim of this study is to determine the antioxidant potential and anti-proliferative activity of Curcuma zedoaria Rosc extract on Hela cells. Two types of materials, such as water and ethanol extracts, were tested at different dose levels (1, 5, and 10%). The potential of antioxidant extract was tested by observing the peroxide value (POV) and prophylactic properties of superoxide (SO). The effects of Cytotoxic extracts were tested by observing the anti-proliferative properties on Hela cell morphology. Results showed that both water extract and ethanol extract contain antioxidants with higher value of superoxide and peroxide than a-tocopherol. Antioxidant potential of Curcuma zedoaria extract is evidential at its high concentration of 10%, but is less significant at lower concentration of 1 and 5%, when compared to the potential of positive control (a-tocopherol) and negative control (non-extract mixture). Antiproliferative activity of Curcuma zedoaria extracts at low concentration (1 and 5%) is not effective. At high concentration of 10%, anti-proliferative activity is effective. Cytotoxic effect of water extract of the rhizome of Curcuma zedoaria at the concentration of 10% changes the Hela cell morphology, but not cell wall rupture. High concentration of ethanol extract causes Hela cells to change its shape, rupture the cell walls, and fragment the cells.

PERANCANGAN TANGKI BIOGAS PORTABEL SEBAGAI SARANA PRODUKSI ENERGI ALTERNATIF DI PEDESAAN Atmodjo, M. C. Tri Biogas Alternative energy Biogas portable tank Anaerobic The increasing price of fossil-based energy and the higher amount of its consumption amidst its limited source would be the main reasons to develop some alternative energy from renewable sources. One of such alternative energy sources is the one from biomass waste, which is easy to find in rural areas as well as in animal husbandry. This biogas portable tank is designed for 160 liters of volume and 75% of this volume is filled with slurry which composes 1 part of cow manure and 1 part of fresh water. The Hydrolysis Retention Time of this slurry is about 20 days and everyday 14.5 liters of old slurry is replaced with the new one and will produce biogas by about 0.56 until 0.68 cubic meters per day, equal to 0.26 kg of LPG. By the assumption that the price of LPG is Rp6,000 per kg and 30 days of operation in a month, the biogas portable tank would get revenue which can cover cost production of the tank in less than 2 years of operation. With its simple design, small scale and lower cost production, and operability, the biogas portable tank is suitable for the production process of biogas and for fulfilling energy needs in rural areas.

An unsafe application of it might affect our health. Pangandaran Village is a malaria and dengue hemorrhagic fever (DHF) in the district of Pangandaran, West Java. The aim of this study is to describe the use of house insecticide by many households in Pangandaran village. An exploratory study with cross-sectional design is conducted for four months starting from April 2014. Several interviews were randomly assigned to 201 households to discover the use of house antimosquito insecticide. Sample collecting method is done using multiple random sampling over each subvillage. The numbers of household interviewed are determined by the proportion number of household in each neighborhood unit (RT). There are 82% households using antimosquito for more than ten years (59%) and using repellent daily (19.4%). Comfort is the main reason why most households use antimosquitos (46%). Households use insecticides one time at night (79.6%) and spend less than IDR 5,000 to buy insecticide. This study provides supporting information for local stakeholders over the use of house insecticide that can be benefitted as a reference for developing policy on vector control disease.

KELAYAKAN USAHA TANI PADI GOGO DENGAN POLA PENGELOLAAN TANAMAN TERPADU (PTT) DI KABUPATEN ACEH BESAR, PROVINSI ACEH Fitria, Eka Dryland Farm feasibility Integrated Crop Management (ICM) Aceh is one of the center of rice production areas in Indonesia. Nevertheless, especially there upland, rice productivity is still very low. The purpose of this study is to determine the feasibility of upland rice farming pattern through Integrated Crop Management (ICM). Location for the study in Tubaluy Village, Darul Imarah Sub-District, Aceh Besar, during May–August 2009, is determined purposively. The study is conducted over an upland area of 3.0 ha property of several farmer. The study involves 8 farmers as well. The results shows that adopting four varieties of rice with the application of ICM is worth the effort, amidst the four varieties potentially yield very well (6–7 tonnes/ha) and are more often planted by farmers for their moderate resistance to blast attack. Highest production capability is found in Towuti (6.29 tonnes/ha) with R/C ratio (2.88). With the application of a ICM, break even production (TIP) and breakeven price (TIH) analysis of four varieties tested (Cirata 62.32%, Limboto 61.40%, Situ Bagendit 62.32% and Tuwoti 65.35%) results that the production of those four varieties will not cause loss since any reducing in productivity or prices will not exceed the value of TIP or TIH. It means the four varieties remain profitable to be produced. The development of dryland rice farming can be carried out by improving farmers’ access to resources, capital, technology, market and productivity through innovation and diversification of production. Furthermore, the development can be established by empowering farmers, develop- ing the institutions needed, and encouraging active participation of all stakeholders.

Characterizing mutan ISSR RAPD Salinity tolerant Drought tolerant Hausa potato (Plectranthus rotundifolius (Poir.) Spreng.) is one of the alternative food for people living in some part of Indonesia. However, its low level of genetic variations has become an obstacle in developing new va- riety. Plant breeding through mutation, e.g. irradiation of γ rays, can be assumed to improve genetic diversity. The aim of this study was to characterize tuber hausa potato mutant irradiated γ rays in salinity and drought tolerant using ISSR and RAPD markers. Five primers of ISSR and five primers of RAPD were used to amplify DNA of hausa potato mutants. Ten primers generated 95% polymorphic and 27 speciific band of irradiated salt-tolerant mutans. Meanwhile, they generated 49% polymorphic and three specific band of irradiated drought-tolerant mutans. The result of the Principal Component Analysis showed that mutants were divided into three groups based on specific bands that play role in the group formation. The result showed that the ISSR and RAPD markers can be reliable to characterize mutants on hausa potatoes.

SOCIETY’S WILLINGNESS TO PAY FOR ENVIRONMENTAL FRIENDLY WASTE MANAGEMENT IN DUSUN TOISAPU LANDFILL, AMBON DISTRICT Ruban, Angela TPA Benefit transfer Contingent valuation method Environmental quality Waste is a national problem in Indonesia. This is related to the old paradigm of waste management which is only collected, transported, and disposed to the landfill. The same problem occured in Dusun Toisapu, Ambon. Since it’s establishment in 2003, Dusun Toisapu landfill used open dumping and it’s caused the increased negative externalities of environmental quality for the people who lives nearby. Ambon district officer has a new integratedwaste management in 2012 but the implementation is not going well because there was no sorting of waste (organic and anorganic) on source of waste. The governments finacial limitation causes the waste management services not running properly. Based on the results of research in Baguala and Nusaniwe, most people are willing to pay higher retribution for better services in Dusun Toisapu landfill with four scenarios. The highest average WTP in Baguala is Rp24.250,00/family/month for biogas scenario and the lowest is Rp20.804,00/family/month for incineration scenario. In Nusaniwe, it is obtained the highest average WTP is  p21.228,00/family/month for composting scenario and the lowest is Rp18.220,00/family/month for sanitary landfill scenario. Value of WTP from people can cover operational costs for implementing four waste management scenarios that offered.
