STUDI KARAKTERISTIK FISIK DAN MEKANIK KAYU KENANGA CANANGA ODORATA

Abstract

Kenanga wood (Cananga odorata) is a local wood in Minahasa with limited technical data for civil engineering despite its traditional usage. This study aims to evaluate its physical and mechanical characteristics as an alternative construction material. Using quantitative experimental methods at the UNIMA civil engineering Laboratory based on SNI and ASTM standards, the study assessed various physical and mechanical parameters. Results indicate an average specific gravity of 0.48 g/cm³ and equilibrium moisture content of 55.8%. Mechanical testing revealed a compressive strength of 22.31 MPa, tensile strength of 116.41

MPa, shear strength of 8.01 MPa, MOR of 300.82 kg/cm², and MOE of 8,161.30 MPa. Classified under Strength Class III–IV according to PKKI NI-5 1961, Kenanga wood exhibits excellent tensile strength. It is deemed suitable for light to medium construction, such as roof trusses, provided it undergoes controlled drying to ensure dimensional stability
