Quality of Particle Board of Rubber Wood Hevea brasiliensis Muell Arg and Tali Bamboo Gigantochloa apus Kurz with Wood Liquids Adhesive

As an effort to utilize rubber•wood tuasteand the abundant resourceof tali bamboo a stucfy of producingparticle board using a mix of the two materialsiuas conducted. In addition,in order to find an alternativeto syntheticadhesive, natural adhesive of wood liquid was used.This research n/as conducted in a 3 x 3 factorialanalisys in acomplete randomized block design with two replicates. Thefactorsstudied were the type of particles (rubber, bamboo ropeand mixtures with a ratio of 50: 50 l?J oven dry weight) and levels of adhesive (10%,15% and 20%.Results showthat1Pood liquids adhesive is characterisedwith pH< 1,viscosity 2,03 poise, solid content 91%,gelatin time (90) 9 min 48 sec, spesificgravity 1, 15 3 and havingblack colour.The characteristics do notJ111ftlreq11iremet1tof SN! 06-0121-1987 forphenol adhesive.The producedparticle boardhas a density of 0,83 g/ cm',moisture content 6,9%,thicknessswelling 19%,uater adsorbtion 28%, MOE 10540 kg(/cm',MOR258 kg//en/, and Internal Bond (IB) 2,2 kg(/cm'.The characteristics also do not ymftll the requirement ojSNI 03-2105-1996jor tnedium density particleboard. Further researchis still neededto meetthe SN!requirements.
