Analisis Karakteristik Briket Bioarang Kulit Singkong dengan Penambahan Variasi Perekat Tepung Tapioka

Abstract

Energy use and consumption in Indonesia only focuses on the use of fossil fuels which are used continuously and are now running low. There are many alternative energies that can be used as potential fuels in the use and consumption of energy, which are quite abundant in quantity but have not been optimized. Biomass energy has great potential to be used as renewable energy. Biomass energy sources can come from agricultural products that are not used or from agricultural industrial waste. One of the uses of biomass is to make it into a solid fuel or charcoal briquettes. There are many potential raw materials for making bioarang briquettes, one of which is cassava plant skin. This study aims to determine the characteristics of combustion (calorific value, moisture content, ash content, combustion rate, combustion temperature and firmness) in the manufacture of bioarang briquettes with the addition of tapioca adhesive. This is expected to produce quality briquettes and provide many benefits.The variable in the research on making cassava skin biocharcoal briquettes was the variation of adding tapioca adhesive. There were 3 adhesive treatments added, namely 10%, 15% and 20%. The analysis of this study used a one-way ANOVA test to determine the effect of adding tapioca adhesive variations. In the follow-up test using the tukey test to find out the mean pairs of treatments that were significantly different. The results of the analysis carried out in this study showed that the best briquette composition was based on the three treatments of adding tapioca flour, namely the highest calorific value in treatment C of 5734.190 cal/g, the lowest moisture content in treatment A of 3.804%, the lowest ash content in treatment A of 8.111%, the highest burning rate was in treatment C of 0.243 g/minute, the highest burning temperature was in treatment C of 189.14°C and the highest firmness was in treatment C of 8.6164 kg/cm2.
