MAKING BRIQUETTES FROM ORGANIC WASTE, COFFEE GROUNDS AND TEA GROUNDS USING SAGO FLOUR ADHESIVE

Abstract

ABSTRACT

To meet Indonesia's current energy needs, most of its oil and gas resources are utilized. Biomass is one of the renewable energy sources due to its abundant availability, environmental friendliness, and affordability for the public. This research aims to develop biomass briquettes as an environmentally friendly alternative fuel made from organic waste. The primary raw materials used in this study are coffee grounds and tea waste, with sago flour as the binder. The research was conducted at the Pilot Plant Laboratory and Unit Operation of the Chemical Engineering Department at Politeknik Negeri Lhokseumawe from May to June 2024. The research procedure includes raw material preparation, combustion process, briquette molding, and testing, including moisture content analysis, ash content, volatile matter, and flame test. The results showed that briquettes with a 40:60 mixture of coffee grounds and binder at 20 grams exhibited the best characteristics, with a moisture content of 65.5%, ash content of 23.4%, an ignition time of 6 minutes, and a burn duration of 64 minutes. This research contributes to the development of efficient and environmentally friendly biomass briquette production technology, as well as opens opportunities for the utilization of organic waste in the
