Kajian Karakteristik Biobriket dari Batang Singkong dan Serbuk Gergaji

Abstract

Indonesia is an agricultural country with abundant biomass energy sources, one of which is cassava. Sawdust waste is one such abundant and underutilized material. Biobriquettes are lumps of charcoal made from organic waste charcoal powder, molded and used as an alternative fuel to petroleum. This study used the ANOVA test method and Duncan Multiple Range Post Hoc Test with a significance level of 0,05 and 0,01. The test parameters were moisture content, density, combustion rate, ash content, calorific value, and flame. The results showed that the characteristics of the charcoal briquettes had a significant effect on moisture content and combustion rate, a significant effect on density, calorific value, and flame, and no significant effect on ash content. Duncan's further test results showed that the composition of 25% cassava stem charcoal briquettes and 75% durian sawdust (P4) was the best raw material composition because it was at the highest variable in 3 stages of testing including density (1.548 gr/cm3 ), combustion rate (0.279 gr/minute) and flame (114 minutes). The analysis results showed that it met SNI in terms of calorific value, density and ash content.
