The main objective of this research is to find out the substitution of construction board (lumber and plywood). For this purpose, research on com-ply, one of panel product and also a structural wood composite products, is determined as one of the composite boards, which is made of veneer on the face/back layers and particleboard on the core layers. Com-ply is a very good product because it can use lignocellulotic material waste in the core layer and using thin veneer in the face and back layers. In this research, oil palm stemand waste paper at different ratio (100:0.75:25,50:50, 25:75 and 0:100) were used as core and Meranti veneer was used as face/back layers and bonded by Urea Formaldehyde (UF) at 10% based on the particle and veneer oven dry weight. The result obtained are as follow: 1) Physical characteristics met JIS A 5908 - 2003, about 0.59 - 0.71 g/cm3 for density and 9.061 - 11.123% for moisture content. 2)Dimensional stability for all samples were vary at different ratio of core material 3) The MOR for length direction were fulfil JIS Standard A 5908-2003 the range were 683-3207 kgf/cm2 4) Unfortunately, the MOE for length direction did`nt require JIS Standard 5)Internal bond (IB) as one of mechanical characteristic was vary at different ratio of core material. 6) Screws holding strength were increased due to the increasing of waste paper in the core layer, the range were 13-43kgf.
