KARATERISTIK SIFAT FISIKA DAN MEKANIKA PAPAN LAMINASI KAYU BAYUR (Pterospermum diversifolium) SEBAGAI BAHAN SUBSTITUSI PAPAN SOLID

Abstract

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
