Abstract
The increasing energy needs must be balanced with the availability of the right energy, namely by efforts to use new and renewable energy sources (NRE). Bio-pellet is one of the renewable alternative energy that has great potential in Indonesia. In this study, bio-pellets were made into two compositions with the raw materials used, namely coconut coir waste, rice husks, and sawdust. The composition of bio-pellet A was made in a ratio of 1:1:1 and the composition of bio-pellet B was made in a ratio of 1:0,5:0,5. The purpose of this study was to determine whether there is a significant difference between the calorific value of the two bio-pellet compositions and to determine the composition of the raw materials that can produce the best quality bio-pellet. The method used in this study is the hypothesis test of the difference between the two averages. The results of the hypothesis test indicated that there is a significant difference between the average calorific value of bio-pellet composition A and composition B. Thus, the difference in the ratio of the composition of the raw materials used has an influence on the calorific value of the resulting bio-pellet. The test results showed that the bio-pellets with the best quality are bio-pellet composition A with a density value of 1.51 g/cm3, water content of 9.9%, ash content of 13.65%, content of volatile matter 61.625%, fixed carbon content of 14,825%, total sulfur content of 0.05%, and calorific value of 3458.5 kcal/kg.
