Currently, it is increasingly difficult to obtain large and quality sawn timber due to the diminishing supply of wood in natural forests. To overcome this problem, innovation is needed to utilize wood scrap waste as a board product. One form of innovation in the use of wood scrap as a board product is laminated boards. In this study, Sengon and Bayur woods were used which had strong grades III-IV and had specific gravity ranging from 0.29-0.70. Bayur and Sengon wood are suitable to be used as raw materials for laminated boards because they have a light density. The purpose of this research was to determine the physical and mechanical characteristics of laminated boards, the effect of Labur weight, wood species and their interactions. The method used in this study is an experimental method with a factorial completely randomized design (CRD). Characteristics of physical and mechanical properties of laminated boards of Sengon and clothes: density 0.412 gram/cm3; water content 12,459%; thick development 2.019%; thick shrinkage 3.183%; MoE 23031,922 kgf/cm²; MoR 357.208 kgf/cm². Laur weight, type of wood and their interactions have a significant effect on all physical and mechanical properties of Sengon and Bayur laminated boards. The interaction of pumpkin weight and wood species had no significant effect on the water content and MoR tests. Based on the wood strength class, Sengon and Bayur wood laminated boards are classified as class III which can be used as protected heavy construction materials.

The centre of bamboo crafts in Gunung Sari District is the largest bamboo centre in West Lombok Regency. One of the bamboo species which is usually used as raw materials is tali bamboo. Studies of physical properties of this bamboo have not been carried out resulting poor quality of bamboo crafts. The physical property was essensial information which would be used for enhancing the products because it correlated with dimensional stability of the bamboo. The objectives of this study were to identify the physical properties of the bamboo with reference to the axial direction. The experiment design was complete random design employing the axial directions (bottom, middle, and top portions) as treatments. The statistical analyses were Anova with range tests at α = 5%. The results showed that the physical properties were: fresh moisture content 51-119.82%; air-dried moisture content 13.03-15.04%; fresh volume density 0.51 – 0.72; air-dried volume density 0.62 – 0.75; oven volume density 0.63 – 0.78. Axial directions of the physical properties were not significantly different except for the fresh moisture content. Therefore all portions of tali bamboo (bottom, middle, and top portions) could be utilized as raw materials for bamboo crafts.

Bayur wood is included in strong class III with a specific gravity ranging from 0.30-0.70 (average 0.53) and has a slightly rough texture but generally has a smooth and shiny surface. This research will look at the characteristics of bayur wood laminated boards as a substitute for solid boards. To determine the quality of the laminated board produced, it is necessary to test the physical and mechanical properties of the resulting laminated board. The method used in this study used an experimental method with an experimental design using a non-factorial Completely Randomized Design (CRD). Based on the results of the research on bayur wood laminated boards, it can be concluded that the value of the physical and mechanical properties of laminated boards has met the standards of SNI 03-2105-2006 and JAS JAS 234-2007 except for the thickness shrinkage and Modulus of Elasticity (MoE) tests. Laur weight treatment did not significantly affect all tests of physical and mechanical properties of Bajur wood laminated boards except for testing the moisture content and Modulus of Rupture (MoR). Based on the standard of wood strength class, laminated boards from Bayur wood are equivalent to wood with strength class III
