Abstract:
Increased population growth causes the demand for fossil fuels to increase while the availability of these fuels is running low, so research needs to be done to find environmentally friendly alternative energy. Biopellet from a mixture of Ironwood and mixed wood (Meranti and Balsa) sawdust waste is one of the solutions in overcoming the energy crisis in the future. The objectives of this study were (1) to determine the biopellet characteristics from a mixture of Ironwood and mixed woods sawdust such as moisture content, density, volatile matter content, ash content, calorific value and fixed carbon content, (2) to identify the influencing factors in the manufacture of biopellet, (3) knowing the best quality of biopellet from various mixtures of raw material variations. This study used a completely randomized design with 5 treatments and 3 replications. The result of this study that the best biopellet characteristics were found in treatment B (70% of Ironwood + 30% Meranti and Balsa mixed wood sawdust waste) with moisture content value of 2.150%, a density of 0.773 g/cm3, volatile matter of 68.450%, ash content of 1.204%, calorific value of 4,830.930 cal/g and fixed carbon value of 27.943%. Finding demonstrates that factors that influence the making of biopellet are the raw material and the processing process
