The problem is the abundance of waste is currently not fully utilized. With the development of technology, the bark can be used as material for making particle board instead of solid wood boards. This allows performed because, oil palm is a tree containing lignoselulosa fibers that are similar to wood. It can therefore be use as panel products like particle board. This study aims to (1) Making particle boards, (2) Study the physical and mechanical properties of particle board from oil palm midrib. The results showed that the addition of adhesives has improved resistance to water particle board. The use of adhesive has a value of 20% water content, thickness, the absorption of water, and the density of the best particle board that is 7.99%, 2.19%, 9.12% and 1.28 kg/cm2. Physical properties of the tested values in the poor with the use of adhesive particles by 20%, in compliance with JIS Standards.enUR-Scientific Work Lecturer
