Effect of Different Portion on Calorific Value, Ash Content, and Specific Gravity of Leucaena leucocephala Wood
The effect of tree portion on the calorific value, ash content, and specific gravity of Leucaena leucocephala wood was investigated using 2-year-old tree. Wood samples of Leucaena leucocephala were taken from three portions, namely top, middle, and bottom. Sampling was carried out according to the standard of Technical Association of the Pulp and Paper Industry (TAPPI) for ash content and calorific value was measured using bomb calorimeter. The results indicated that calorific value was found to be higher at the bottom and the trend increased from top to bottom portion. Specific gravity shows similar pattern to calorific value. However, the ash content of Leucaena leucocephala wood decreased from bottom to top portion. This study reveals that tree portion showed no significant effect on the ash content, specific gravity, and calorific value. This implied that the whole tree stem of 2-year-old Leucaena leucocephala wood at 2 years old could be used for source of biomass for renewable energy material.
