| dc.description.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. | en_US |
