Abstrak
: Red jabon (Anthocephalus macrophyllus) is a fast-growing wood species with potential to be developed as a source of timber raw material from community forests. Information on the physical properties of red jabon wood at a young harvesting age is still needed to determine its appropriate utilization. This study aimed to evaluate the physical properties of 6-year-old red jabon wood from Parasi Village, South Palangga District, South Konawe Regency, Southeast Sulawesi Province, based on the axial position of the stem. The study used a one-factor completely randomized design, namely stem position, consisting of the base, middle, and top sections, with nine replications. The observed parameters included moisture content, specific gravity, and wood shrinkage in the longitudinal, tangential, and radial directions. The results showed that stem position had a highly significant effect on green moisture content and a significant effect on air-dry moisture content, green specific gravity, air-dry specific gravity, and oven-dry specific gravity. However, stem position had no significant effect on longitudinal, tangential, and radial shrinkage. Red jabon wood had an average air-dry moisture content of 8.797%, an average air-dry specific gravity of 0.422, longitudinal shrinkage of 0.187%, tangential shrinkage of 1.083%, and radial shrinkage of 0.942%. Based on its air-dry specific gravity, 6-year-old red jabon wood from South Konawe is classified as strength class III. These characteristics indicate that this wood has potential for use in light to medium wood products, such as light furniture, veneer, plywood core, crates, boards, particleboard, and pulp raw material, while still considering the drying process and sorting based on stem position.
