KUALITAS PAPAN PARTIKEL KAYU KARET (Hevea brasiliensis Muell. Arg) DAN BAMBU TALI (Gigantochloa apus Kurz) DENGAN PEREKAT LIKUIDA KAYU

Abstract

As an effort to utilize rubber wood waste and the abundant resource of tali bamboo a study of producing particle board using a mix of the two materials was conducted. In addition, in order to find an alternative to synthetic adbesive, natural adhesive of wood liquid was used. This research was conducted in a 3 x 3 factorial analisys in acomplete randomized block design with two replicates. The factors studied were the type of particles (rubber, bambino rope and mixtures with a ratio of 50:50 by oven dry weight) and levels of adhesive (10%, 15% and 20%. Results show that wood liquids adhesive is characterised with pH <1, riscosity 2,03 poise, solid content 91%, gelatin time (90) 9 min 48 sec, specific gravity 1,153 and having black colour. The characteristics do not fulfil requirement of SNI 06-0121-1987 for phenol adhesive. The producced particle board has a density of 0,83 g/cm², moisture content 6,9%, thickness swelling 19%, water adsorbtion 28%, MOE 10540 kgf/cmỉ, MOR 258 kgf/cm², and Internal Bond (IB) 2,2 kgf/cm². The characteristics also do not fulfill the requirement ofSNI 03-2105-1996for medium density particleboard. Further research is still needed to meet the SNI requirements.
