Abstract

Oil palm empty fruit bunches (EFB) is one of lignocellulosic natural resource, which is highly potential as adhesive and particleboard raw materials. The purpose of the study was determine wood liquid qualities, and to evaluate the effect of adhesive contents, wood liquid extension levels on melamine formaldehyde (MF) resin, and resorcinol formaldehyde (RF) fortification levels on wood liquid to particleboard quality. The results showed that the EFB wood liquid is considered as phenolic resin group, liquid form and free of dirt, reddish brown color, pH 11, 34 cps viscosity, solids content of 34.47%, and gelatine time >60 minutes. Some characteristics of wood liquid adhesives meet SNI 06-4567-1998, namely the form, appearance, pH, and gelatine time. The physical and mechanical properties of particle board for all treatments were 0.64-0.93 g/cm3 density, moisture content 6-12%, thickness swelling 13-292%, water absorption 39-239%, modulus of rupture (MOR) 16-199 kg/cm2, modulus of elasticity (MOE) 2321-19810 kg/cm2, internal bonding 0.16-7.19 kg, and screw holding power 16-62 kg. Some physical and mechanical properties of particle board meet the standard of JIS A 5908-2003. Particleboard using MF resin without wood liquid extension (adhesive content of 20%) was the best quality particleboard. Wood liquid for particleboard recommended using wood liquid fortified with 5% MF resin (adhesive content of 15%) and MF resin with 15% wood liquid extensions (adhesive content of 20%) produced good quality particleboard.

Abstract

Cement boards was made ​​from bamboo hitam (Gigantochloa atroviolacea Wdjaja) using two particle sizes of 20 mesh and 40 mesh. The difference in particle size thought to affect the quality of the resulting cement board. The purpose of this study was to evaluate the physical and mechanical properties of cement board bamboo hitam using two  particle sizes.Boards were made ​​with size 25 cm x 25 cm x 1 cm with density of 1.2 gr/cm3 of two different particle size of 20 mesh and 40 mesh and each made ​​in three replications. Cement board was made with ratio of particles, cement and water in 1:3:2 and the addition of MgCl2 catalyst was 5%. In general, physical properties of  cement board had completed the standard JIS A 5417-1992, both cement board particle size 20 mesh and 40 mesh. Physical properties of  cement board using particle size of 40 mesh better than  cement board using particle size of 20 mesh. MOR value of  cement board using particle size of 20 mesh had met standard while the value of MOE did not complete the standard. Internal bond and screw holding strenght did not require in standard JIS A 5417-1992.
