The depletion of fossil fuel reserves is increasingly encouraging people to see other renewable energy sources. Strategic steps can be taken is applying the concept of energy diversification. One of the simplest and easiest ways to diversify energy is through biomass energy utilization. Indonesia has abundant biomass energy sources, which can come from waste. Potential wastes that can be used as raw material for briquettes are sawdust and coconut shell waste. The purpose of this study was to

The research is done with variating of adhesive concentration 4%, 6%, and 8% with sawdust and coconut shell composition 75%:25%. The research result shows that briquettes with 4% of adhesive concentration have caloric value 6974.022 Cal/g, moisture content 4.518%, and ash content 1.364%. Briquettes with 6% of adhesive concentration have caloric value 7561.582 Cal/g, moisture content 4.232%, and ash content 1.762%. Briquettes with 8% of adhesive concentration have caloric value 6996.102 Cal/g, moisture content 4.455%, and ash content 1.623%. The characteristics of briquette have fulfilled the value of briquette quality standard SNI 01-6235-2000. The most optimum of adhesive concentration in briquette production from the research was 6%.
