Effect of Heated and Non-Heated Treatment of Cinnamomum porrectum Extract on Rubberwood and Oil- Palm Trunk Veneer against Fungi

Abstract

ubberwood veneers and oil palm trunk (OPT) veneers currently widely used as a finishing in the timber industry. Various technique of treatment was used nowadays to maintains the durability of these materials. In this study the susceptibility test of rubberwood veneers and OPT veneers was exposed to wood deteriorating fungi. This study conducted to investigate the effect of heated treatment and non-heated of extractive to the weight of veneers. Two wood rotting fungi (brown-rot and white-rot) were cultured into the veneers being treated with either heated or non-heated C. porrectum extract. The result of attacking pattern was observed by light microscope. The weight losses due the exposure were compared. Veneers treated with heated extractives tend to have lowest percentage of weight loss with 20.08% for rubberwood veneer and 39.35% for OPT veneer compare to veneers that treated with non-heated extractive with 23.11% for rubberwood and 39.85%. This study indicates with advent of heat it helps the rate of absorption of extractive into the veneers to control the fungal deterioration on rubberwood veneers and OPT veneers
