Abstract

Biomass waste that has not been utilized properly is rice husk and jatropha seed waste, and there is a future need for efficient utilization of these wastes. Rice husk is the outermost part of the rice seed, the rice milling process produced 20% - 30% of the waste as rice husks. Jatropha seed waste is a de-oiled part of jatropha seed after the oil extraction process for biodiesel production, and produced 70% of waste. As biomass, both materials are potential sources of carbon that can be utilized as an alternative energy sources such as bio-briquettes. The method used in this research is experimental method including drying of the biomass material sample, carbonization process, refine and filtration using 40 mesh sieve (420 μm). The composition of the selected charcoal mixture is fixed at 50:50, and the addition of the waste newspaper pulp as and adhesive material with variations of 8% and 12% by weight. Characterization is done by using proximate test, calorific value test and compressive strength test. After going through pressure printing and drying process, the briquettes with 8% addition of waste newspaper pulp adhesives have the best value of compressive load test results and has the highest heat energy content, equal to 5.650 cal / g.
