Abstract

Sawn wood with large dimension and high grade are more difficult to be • found in the market due to decreasing in stock dimension. Indonesia has alternative trees wich sources oil palm trunk; however, it has low quality and limited in usage. To obtain a better performance of oil palm trunk, the tree needs to combine with high-grade wood to produce glue laminated timber. This research objective is to produce glue laminated lumber OPT that combine with others commercial timber (this research used Rengas (Gluta L. Anacardianceae)). Preliminary testing was done to obtain physical and mechanical properties of clear specimen on OPT, testing method base on IS0-1975 standard. Glue laminated lumber specimens had 40 cm in wide, 4 em in depth and 80 em in length; they were made in five models. Each layer of lumber glued with thermoselling urea formaldehyde adhesive at pressure 0.9 MPa for 10 hours pressing time. The testing result of physical and mechanical OPT was of low density and strength class V up to III. Glue laminated lumber shows all products have interesting performance.
