Abstract The current research focuses on the utilization of branches and twigs of surian as raw material for making composite boards in an effort to utilize the waste part of surian stem wood waste. The types of particle board and oriented strand board were bonded with phenol formaldehyde (PF) of 10% resin content. Variations of board density and board types were focused in this research. The boards were evaluated based on Japanese Industrial Standard (JIS). The results showed that the density of the board affected the physical and mechanical properties of the composite board. Strand boards were better than particle boards with regard to mechanical properties. Physical properties that met the testing standards were moisture content, density, water absorption and thickness swell for both after soaking 2 h in water, while for the mechanical properties test, only modulus of elasticity (MOE) met the standards. However, for further study, it seemed that generally this initial study informed that it was possible to make composite boards from the raw materials, both branches and twigs, with the additional treatment such as changing the size of particles and strands that could improve the properties of the board.
