Abstract

This study aims to compare the physical and mechanical properties of Eucalyptus wood clone K56 from three different areas: forest planting area, natural forest area, and near water area. The properties were tested according to BS 373 standard (1985) and ASTM D 143 standard (2014). Green moisture content, specific gravity, modulus of rupture, modulus of elasticity, compression parallel to grain, compression perpendicular to grain, hardness, and shearing stress parallel to grain were measured. Each area was tested in 5 replications. The results showed that Eucalyptus wood from the forest planting had the best physical and mechanical properties. The average green moisture content was 27.39±2.49%, the average moisture content before testing was 10.02±1.21%, the average specific gravity was 0.70±0.03, the average modulus of rupture was 93.94±4.26 MPa, the average modulus of elasticity was 8,969.16±94.94 MPa, the average compression parallel to grain was 49.42±2.48 MPa, compression perpendicular to grain was 7.58±0.65 MPa, the average hardness was 5,691.29±129.07 N, and shearing stress parallel to grain was 12.26±1.01 MPa. These results indicate that good silvicultural practices in managing plantation forests lead to improved wood properties and quality.
