Daftar Isi:
- The limit of energy resources in Indonesia and the increase the price of fuel oil encourage people and industry to find alternative other renewable energy resources such as wood biomass. Papua has a large area of production forest, including forest in Merauke. Forest in Merauke is potential for pulp and wood industrys that generate a large waste of biomass. This study investigated the Calorific value of wood and bark of five species. Testing from these five different wood species was carried out in order to find the value of energy obtained from wood and bark of five species of forest in Merauke. The materials used in this research were wood and bark of five trees species which were Acacia mangium, Acacia crassicarpa, Eucalyptus pellita, Melaleuca viridiflora,and Lophostemon suaveolens. The experiment was carried out based on ASTM (American Standard of Testing Material). The test of calorific value was carried out using bom calorimeter. The physic and proximate test were moisture content, specific gravity, ash content, volatile content, and fixed carbon. The Fuelwood Value Index was calculated based on the calorific value, specific gravity, and ash content. This research using completly randomized factorial design and arranged in factorial with two different factors were the tree species and the tree components i.e. bark and wood. The calorific value of the wood of five trees species (Acacia mangium, A. crassicarpa, Eucalyptus pellita, Melaleuca viridiflora and Lophostemon suaveolens) respectively 4,066 kal/g, 4,701 kal/g, 4,241 kal/g, 4,088 kal/g, 4,513 kal/g and the bark respectively 4,639 kal/g, 4,374 kal/g, 4,403 kal/g, 5,435 kal/g, 4,406 kal/g. The moisture content, specific gravity, ash content, volatile content, and fixed carbon are respectively 15.9%, 0.637, 0.88%, 81.6%, and 17.47%. No significant difference of the calorific value among species caused by the similar value of volatile and fixed carbon. The calorific value between wood and the bark were significantly different with the average 4,652 kal/g and 4,322 kal/g respectively. The calorific value of wood was higher than the bark closing by the lower volatile matter content in the bark.
