The demand of wood as a structural component in the construction works are increasing with the increase of human population. This increase is not accompanied by the increasing number of wood production, thus leading to difficulties in obtaining the wood on the market. To overcome the difficulties of wood as a structural component, it can be used on other types of materials which is a way of optimizing the waste of Sago wood located in Maluku, especially Ambon Island. This study is aimed to determine the physical properties and mechanics of laminated Sago wood which refers to SNI-02, 2002 and SNI-03, 1995. On structural sized wood is performed to determine moment capacity, bending rigidity and failures in the form of laminated Sago wood. Testing of physical properties include density, moisture content and testing of mechanical properties (flexural strength, compressive strength, tensile strength and shear strength). Testing wood sized structural performed on three models of glulam beams with dimension 50 x 100 x 2000 mm, viz the one the beam without connection (KSL-01), a single the beam by using a connection on the center of the beam to the shape of V inverted (KSL-02) and the one the beam variations connection (KSL-03). Manufacture of laminated Sago wood specimens using polyurethane adhesive types. Loading system is conducted by four-point loading. The tests are conducted to determine the flexural behavior of laminated Sago wood that can be used as a floor structure. The result shows Sago wood density analysis are still higher when compared with low quality wood such as Sengon wood with an average moisture content of 12.56%. Elasticity modulus of wood mechanical properties of Sago including wood quality of E16, while the testing of structural sized wood including wood quality of E17 where flexural strength, compressive strength parallel to the fiber, parallel fiber tensile strength was higher when compared with the SNI standard, but for shear strength was still lower. The moment capacity of the beam models KSL-03 is 1.35 times than the beam moment capacity at KSL-01 models. Results of analysis bending stiffness that occurs in the beam models KSL-02 is 1.2 times than the beam bending stiffness on KSL-01 models and the model of beam bending stiffness KSL-03 is 1.19 times than the beam bending stiffness on KSL-01 models. Form of failure that occurs due to damage to the wood fibers sliding on Sago. The slope of the adhesive (glue-line) connection between the lamina does not have a significant influence, but the damage to the joint is commonly caused due to a shift in wood fibers giving rise to the effect on the strength and stiffness of glulam Sago wood. Based on the analysis of the testing that has been done, the Laminated Sago wood can be used as a structural component of the floor when the flexural stiffness and moment capacity is increased by using a larger dimension.
