“…The sample size was determined by considering the research method, by cutting down trees and collecting parts of trunks for the replicate samples. This method was carried out by Lukmandaru (2018) using one sample of E. pellita tree, and by Ohshima et al (2019) using two trees of both E. camaldulensis and E. globulus . Other materials were distilled water, alcohol, benzene, acetic acid, sodium chlorite, acetone, sulphuric acid and sodium hydroxide for wood chemical testing.…”

The anatomical and chemical properties of a lesser known species, Kawui wood, were investigated Two trees were examined based on IAWA, ASTM and SNI. A completely randomised design was used with radial direction of the trunk (sapwood and heartwood) as the factor, in three replications. It indicated the highest to lowest cell proportions are fibres, rays, vessels and parenchyma. The highest proportion of rays was in the sapwood, while the fibre was in the heartwood. However, the average fibre length in the sapwood was higher than the heartwood, while the lumen diameter showed the reverse. Holocellulose, αcellulose, lignin, extractives, and ash content of the sapwood was higher than the heartwood. Based on its anatomical and chemical properties, Kawui wood can be included in grade II-IV, which is suitable for medium quality pulp and paper production.
