Abstract:
The objective of this research was to evaluate of physical and
mechanical properties three species of Styrax wood origin from North Tapanuli. Plants
age for samples were more than 15 years old. Small clear specimen test based on
BS-373 standard for physical properties parameters such as specific
gravity, green moisture content, and volume shrinkage. Furthermore, the mechanical
properties test included of modulus of rupture, modulus of elasticity, compression
parallel to grain and hardness. The
results showed that According to stem direction, edge section had better
properties compared to near pith section.
While for base section had better properties than upper section. Based on that specific gravity, all of the
Styrax wood in this research was classify into III-IV strength classes. Styrax
wood had good dimensional stability, it showed by the tangential and radial
ratio value reached of one. According to
the mechanical properties, styrax wood was suitable use for raw materials of
light consttruction, furniture and handy craft.
