In the present study is carried out by varying the material composition of the briquettes and the particle size of 25 mesh material. Then do a calorific power test using a bomb calorimeter. Based on the research results obtained kinds of briquettes that has the highest heating value of wood tamarind material composition: 50 grams, sawdust: 25 grams, cow dung: 10 grams, adhesive materials: 15 grams  white the calorific value generated 4696.8990 calori / grams. For this type of briquettes with low calorific value, with the composition of the wood used is the acid: 15 grams, sawdust: 15 grams of cow dung: 35 grams, and sawdust: 35 grams.
