The objective of the experiment was to analize the effect of acetic acid treatment and JFH/non-wood particle ratio to physical and mechanical properties particleboard. Non-wood particles used in this experiment namely bamboo and sorghum bagasse. For the particle treatment, JFH and non-wood particle immersed in 1% acetic acid solution for 24 hours. The untreated particle also prepared for bamboo and sorghum bagasse. The ratio of JFH/non-wood particles was 100/0, 70/30, 60/40, 50/50, and 0/100. The board size, thickness, and density target were 30 x 30 cm2, 1 cm, and 0.70 g/cm3, respectively. Particles sprayed using 10% UF resin (SC: 63%). Afterward it was pressed using the hot pressing machine at the temperature of 130 oC, the pressure of 2.544 N/mm2 and 10 minutes time of pressing. Conditioning was conducted around seven days at room temperature before physical and mechanical test. That properties test refers to JIS A 5908 (2003). The results showed that 50/50 (%w/w) JFH and bamboo ratio produced of better thickness swelling value compared to another ratio. Therefore, combination JFH and bamboo acid treated resulted in the best of thickness swelling value. A similar trend also showed in mechanical properties. That treatment produced the best of the modulus of elasticity, modulus of rupture and internal bond value.
