There is corncob waste, precisely in Pringgabaya village, East Lombok district. There is a scarcity and an increase in the price of mineral fuel, the effect is almost felt by all circles of society, both from industry and civil society. This type of research is experimental research in the laboratory. In this study used a composition with 95 ATJ +5% adhesive, 90% ATJ + 10% adhesive and 85%+15%. The resultsobtained are briquettes that have the highest heating value, namely box-shaped briquettes with a mixture of 5% adhesive, the resulting calorific value is 25,200 (J) or 6,800 (cal). While the lowest calorific value is tube-shaped briquettes with 5% adhesive mixture, the resulting calorific value is 9,576(J) or 2,280 (kal). While the value of the combustion rate of each briquette where the highest combustion rate is 17,925 grams/minute box geometry with a composition of 15% adhesive, while the lowest combustion rate is 3,33 grams/minute tube geometry with a 5% adhesive composition.
