The aim of this research was to make particle board from coconut frond powder with various grain size. Particle board test pieces are made by mixing coconut frond powder with various grain sizes, namely 10; 25; 50 and 75 mesh with 40% of liquid rubber compound to obtain a particle board test pieces with the length, width and height of 5 x 10 x 7.5 cm and then dried in the sun. Then the particle board test pieces pressed to a thickness of 2.5 cm and then characterized its strength which includes the modulus of rupture (MOR), the modulus of elasticity (MOE), the Screw Hold Strength and water absorption. The results of this research indicated that the best strength of particle board was obtained on the use of 50 mesh coconut front powder and 40% liquid rubber compound as the adhesive. On this mix, the value of MOR, MOE, the strength of the screw and water absorption of resulting particle board are 1528.32 g/mm2, 618.18 g/mm2, 4.9111 N/cm2 and 26.87% respectively.
