Oil palm (Elaeis guineensis Jacq.) provides raw materials for food, edible products, chemicals, household care, and energy materials. The tree has an economic life of approximately 25 to 30 years, upon which the tree is felled for replanting. Currently, several million trees are scheduled to be felled every year and considered a waste. The oil palm trunk (OPT) could be an option for substituting wood panel product. The improvement of recovery rate of OPT is expected to increase the effectiveness of OPT utilization as a wood substitute. The aim of this research was to examine the effect of different age OPTs on the productivity and characteristics of the OPT lumber. This study observed recovery rate and physical properties of sawn oil palm trunk which cut into three parts (bottom, middle, and top portions). The recovery rate determining the log volumes as the input and sawn OPTs volumes as the output. Meanwhile, the physical properties was referring to ASTM D 4442−92 for moisture content and ASTM D 2395 −14 for density and specific gravity. The recovery rate of 32-year-old sawn OPT (65.165%) appeared to be higher than the sawn 37-year-old OPT (61.675%). The results revealed that the 37-year-old OPT have moisture content, specific gravity, and density values of 197%, 0.322, and 0.404 g/cm3. Similar trends were also recorded for the shrinkage samples. The findings showed that the 37-year-old OPT has higher physical properties compared to the 32-year-old OPT. [ABSTRACT FROM AUTHOR] |
