Abstract

The aim of this study is to obtain the basic wood properties of three lesser known species tengkook ayam (Nephelium sp), madang pirawas (Neolitsea firma) and merambung (Vernonia arborea)). Stem diameter at 1.3 m above the ground and tree height were measured on 3 trees from each species. Later, core samples were collected from all the measured trees. Using the core samples, the basic density (BD), moisture content (MC) and compressive strength with fractometer (fractometer II, IML, German) parallel to grain (CS) were measured. Mean values of BD of tengkook ayam (Nephelium sp), madang pirawas (N. firma) and merambun (V. arborea) were 0.59±0.02, 0.55±0.06 and 0.34±0.06, respectively. Mean values of MC of tengkook ayam (Nephelium sp), madang pirawas (N. firma) and merambung wood (V. arborea) were 22.77±0.10%, 37.10±0.01% dan 61.85±0.06%, respectively. Mean values of CS of tengkook ayam (Nephelium sp), madang pirawas (N. firma) and merambung (V. arborea) were 34.70±11.89 MPa, 32.00±3.39 MPa dan 15.02±4,06 MPa. There is a positive significant correlation between BD and CS.
