Abstract: An effort has been taken to explore fast-growing indigenous of Aras as optional species besides Acacia mangium that prone to a number of diseases. Basic information on engineering properties viz; mechanical and physical properties from different species, and conditions were acquired from strength property’s test namely, modulus of rupture, modulus of elasticity, impact bending, and compression stress parallel to grain. Meanwhile, for physical properties test namely moisture content and density. The test samples were prepared in small clear specimens according to British Standard, BS373.1957. Specimens condition which is referred to as green condition and air-dry condition. Data obtained from this study is very useful for utilization in furniture and engineering construction industries. In this study Aras was compared to Acacia mangium as the reference point use for observation. The results from the study indicated that, Aras gave the average percentage difference of mean for mechanical and physical property with 35% toward the results obtained by Acacia mangium.
Keywords: Modulus of rupture, Modulus of elasticity, Impact bending, Compression stress parallel to grain, Moisture content, Density.
