Making briquettes with agricultural waste raw materials is effective alternative energy for fuel. This study describes the effect of the composition of coconut shell charcoal and durian skin, molasses adhesive and starch on the characteristics of bio briquettes through proximate analysis to obtain the ideal composition. In this study, briquettes were made with a mixture of coconut shell charcoal and durian shell charcoal which were varied (i.e. the ratio of coconut shell charcoal and durian skin charcoal was 65:30, 60:35,55:40,50:45,45:50). Briquettes production is carried out using a furnace at a temperature of 400oC. The resulting charcoal is mixed with different mass ratios and added molasses adhesive. The bio briquettes were analyzed to evaluate the moisture content, ash content, volatile matter, fixed carbon content, burn time, calorific value and morphology. Proximate analysis shows that solid fuel products have almost the same quality as coal, namely the calorific value of 5710.43 cal/g for molasses adhesive. The resulting proximate analysis shows that the resulting bio briquettes have great potential to become a viable fuel source.
