Oil palm trunk quality for veneer and sawn timber productions
2010
Kamarudin H. | Jamaludin K. | Anis M.
A total of 12 felled oil palm trunks (OPT) of Tenera variety were obtained from the Sungai Kahang Estate, Sayong Plantation Sdn. Bhd., located between latitudes N2°12'24" to N2°12'55" and longitudes E103"30'59" to E103"31 '05". The physical and mechanical properties of OPT, computed across its diameter, each taken at different bole heights of one metre intervals were analysed by using variousanalytical techniques. In general, variations in relation to the distance between the bole positions gave variation in the moisture content and basic density distributions. With the exception to moisture content distributions, the samples obtained from thecentre of OPT disc and those subsequent samples towards the east have higher densities compared to the same samples, measured from the centre of OPT towards the west. Based on the results of mechanical properties, it was evident that the intrinsic strength of the woody portion is dependent on the distance across thediameters and heights, measured above the ground. This information is useful to develop a suitable sawing and veneer peeling operations that would minimise the drying degrades (such as twisting, honey-combing, surface checks and collapse) for the sawn lumber and plywood veneer productions, respectively. As a result, thequality of resulting products would be more uniform.
