ABSTRACT
The purpose of this research is to identify the ideal composition of bio-charcoal briquette made of organic waste on heat production. The employed method involved an experiment with a sample briquette with the weight of 120 g obtained using a simple random sampling technique, consisting of 4 treatments with 5 repetitions, i.e. treatment 1 (50% leaf: 40% twig: 10% paper), treatment 2 (60% leaf: 30% twig: 10% paper), treatment 3 (70% leaf: 20% twig: 10% paper), treatment 4 (80% leaf: 10% twig: 10% paper). The results showed that there was different composition variety of organic waste forming the briquette on the heat value (p value = 0.001 ≤ 0.05). Organic waste composition that was most effective in making bio-charcoal briquettes was in the treatment 1 with briquette’s heat value was 4.632 cal / g - 5101 cal / g, with initial temperature of 28° C and final temperature of 85° C and time length needed to become ash was 67 minutes.
