摘要：This study is a preliminary study that aims to determine the quality of briquettes from different biomass raw materials, namely corncobs and teak leaves. Utilization which is still not maximized from corncobs and teak leaves in the biomass energy field made the initial thought of the study. In addition, both of these raw materials have lignocellulosic contents which are likely to be used as biomass raw materials, especially briquettes. The research method used is an experiment with the research procedure is the manufacture of the two briquettes then the products are analyzed and compared. Both of these raw materials receive the same treatment in the manufacturing process. The composition of the adhesive used is 5% of the main ingredient. The adhesive used is starch. Both briquettes were tested for quality including water content, ash content, volatility, and heating value. The results of testing the water content, ash content, volatile content, the calorific value of corn cobs briquettes and teak leaves charcoal briquettes are, respectively, 3.62% and 5.39% water content; ash content of 4.84% and 3.14%; volatile content of 11.75% and 25.86%; The heating value is 5653.99 cal / g and 7222.95 cal / g. From the results of the analysis, teak leaf charcoal briquettes dominate better quality than corn cobs charcoal briquettes, the water content of teak leaf charcoal briquettes is still higher. When compared with the SNI set value, the two briquettes have met the briquette standards that are suitable to be used as substitutes for alternative fuels.
