Karakterisasi Briket Campuran Limbah Serbuk Gergaji Kayu dan Limbah Tempurung Kelapa Sebagai Sumber Energi Alternatif

Biomass is a renewable energy source that can be converted into alternative fuels to replace fossil energy through briquette technology. Sources of biomass that are abundant and have not been optimally used are from pine sawdust waste and coconut shells waste. This study aims to analyze the characteristics of the calorific value of briquettes mixture of pine sawdust waste and coconut shell waste. The research method of making briquettes was done by varying the particle size of charcoal powder, that are 10 mesh, 20 mesh, and 40 mesh. The research was done included several main processess, that are the carbonization process, briquettes production, and testing analysis. The results showed that the resulting charcoal briquettes had an average heating value of 6013.347 cal/g at a particle size of 10 mesh of charcoal powder. At a particle size of 20 mesh, it produces briquettes with an average heating value of 5865.774 cal/g. Whereas at a particle size of 40 mesh, it produces briquettes with an average heating value of 5791.313 cal/g. Briquettes produced by varying the particle size of charcoal powder have met the SNI 01-6235-2000 quality standards. The optimum particle size of charcoal powder obtained in this study is 10 mesh
