Summary : The objective of this research was to obtain the best condition to produce high quality particleboard made of JFH and UF resin. this research consist of five steps. The first step was to analyse of materials characteristic of JFH and UF resin included of pH, buffering capacity, chemical component, chemical component, chemical compound, wettability, solid content, viscosity and gelatine time. Second step,was to analyse of particle immersing treatment (immersing in cold water for 24 hours, hot water for 1 hour and 1% acetic solution) to physical and mechanical properties of particleboard. Third step, was to analyse of pressing temperature and time to obtain optimum pressing condition in particleboard manufacturing. The fourth step was to analyse of wood shaving (mangium wood) and wood veneer (sengson and jabon wood) to reinforce of mechanical properties of particleboard. The last step was to analyse of non wood particle (bamboo and sorghum stalk) to reinforce of mechanical properties of particleboard. The result showed that JFH had alkali properties, it was caused by alkalinefrom several chemical compound that composed of JFH i.e. ammonium bicarbonate,nercaptomethane, guaiacol, 2.6-dimethosyphenol dan cyclopropyl carbinol. immersing treatment was reducing of extractive content, pH and increased of JFH wettability. based on technical and efficiency considering, immering treatment in old water for 24 hours, hot water for 1 hour and 1% acetic acid solution were selected for particleboard manufacturing. The best properties of particleboard was resulted by JFH immering treatment in acetic acid solution. The exploration of pressing temperature and time to oblation of the best pressing condition was expected for optimizing of UF resin polymerization. Hot pressing in 130C temperature for 10 minute resulting the best properties of particleboard, but the thickness swelling and modulus of elasticity value were not fulfill of JIS A 5908 (2003).
