Bamboo (Gigantochloa apus) is a potential material for wood substitution. However, the bamboo uses is limited according to the dimensions. Therefore, it needs modification technology such as transform bamboo into laminated bamboo boards. The combination of bamboo strips and zephyr as well as different fiber directions affected the physical and mechanical properties of laminated bamboo boards. The study was carried out on Gigantochloa apus, which were made into strip and zephyr manually. Each strip and zephyrs are dried and then formed into a laminated board, then glued using isocyanate adhesive (P.I Bond) in a double spread with a weight of 300 g/m2. Arrangement of laminated bamboo boards perpendicularly between face/ back and core (Ply bamboo) and the parallel between face/back and core (Laminated Bamboo Lumber/LBL). The laminated bamboo board was cold-pressed at a pressure of 22.22 kgf /cm2 for 1 hour. Physical properties evaluated by moisture content, density, water absorption, shrinkage and swelling. Mechanical properties evaluated by MOE/MOR, shear strength, and screw withdrawal strength. Machining properties evaluated by sanding and reaping. Laminated bamboo boards have an average moisture content and density that meet JAS standards. The face/back of the strip has better dimensional stability value and higher defect-free value compared to zephyr. The combination of raw materials on the face/back and variations in the direction of the fiber can improve the mechanical properties. However, variations in fiber direction have no effect on the machining properties of laminated bamboo boards made of Gigantochloa apus.
