The use of coconut shells and sugar cane bagasse as the main raw materials for making briquettes hasgreat potential as analternative fuel. The use of briquettes as fuel can produce heat with little smokewhich is environmentally friendly. The aim of the research was to determine the effect of the compositionof bagasse charcoal and coconut shell charcoal and the type of adhesive on the characteristics ofbriquettes. The variables used in this research were the mass ratio of coconut shell charcoal to bagassecharcoal (90:10, 80:20, 70:30, 60:40 and 50:50) with a type of briquette adhesive in the form of tapiocaflour. Researchstages include raw material preparation, carbonization, briquetting and product analysis.The results of the research showed that the best briquette characteristics were found in briquettes withtapioca flour adhesive and a composition of bagasse charcoalversus coconut shell charcoal. The bestcharacteristics of briquettes are that the highest calorific value is in the ratio 60:40, namely 5,663 cal/gr,while the resistance during combustion is in the ratio 90:10, namely 2 hours 15 minutes.
