Background and Objectives: Facing the increasing of wood demand from community forest for timber industries has been urged some Indonesian wood researcher to handle and investigate the suitability of wood species with adequate adhesive to produce the best quality of wood bonded products that could increased the value of the wood from those community forest. The purpose of this study was to utilize and find out the best bond quality of surian wood as a new raw material for laminated wood compared to the commonly wood species used, namely sengon. Material and Methods: Two-ply lamination was produced under room temperature condition. Each lamination were bonded by urea formaldehyde (UF), polyvinyl acetate (PVAc), resorcinol formaldehyde (RF) and aqueous polymer isocyanate (API) resin adhesives at spread rate of 300, 200, 250 and 250 g m–2, respectively, then pressurized at 10 kgf m–2 for 24 h. After conditioned for a week at room temperature of 20°C and 65% humidity, it was immediately followed by physical and mechanical test under JAS standard. Results: The highest bond shear strength with the highest wood failure percentage was the laminated wood of surian bonded with API adhesive rather than PVAc, UF and RF adhesives. It showed that the best bond quality of laminated wood of surian was obtained for laminated wood bonded with API adhesive. Conclusion: Surian wood with the good bond quality than sengon wood has the high opportunity to utilize in Indonesian timber industries for the future, especially for producing the laminated wood bonded with API adhesive.
