Abstract
Coffee grounds are a waste and low-value material. When they were analyzed for chemical composition using the FTIR technique, the coffee grounds appeared stretch the carbon-oxygen bond. The carbon double bond (C=C) and the carbon-hydrogen bond (C-H) of the aromatic ring, are the same elements as other types of charcoal. This research aimed to study the production of fuel briquettes from molded coffee grounds using wet flour as a binder. This was done using coffee grounds to tapioca starch ratio 8:2. The calorific energy test results showed that coffee grounds yielded 5,262.97 cal/g and fuel briquettes provided 5,033.92 cal/g. ASTM D3172 stable carbon content test was 0.07 g/100g with a density of 0.48 g/cm3. Fuel briquettes were analyzed for their chemical composition using the FTIR technique, the result of this was that carbon and oxygen double bonding strips appeared. Carbon double bond (C=C) and carbon-hydrogen bond (C-H) wavelengths range approximately 1,697.19 cm-1, 1,643.64 cm-1 and 1,370.68 cm-1 respectively. The carbon hydrogen bond Stretching band (C-H) wavelengths, range approximately 2,853.88 cm-1 and 2,920.36 cm-1. The thermal performance test in boiling water, showed that the maximum water temperature was 101.2 ๐C, the combustion time was 100 min, the combustion rate was 5.03 g/min, and the actual efficiency was 21.90%. This mean that it has a high combustion rate, and based on these findings, it could be used as an alternative way of producing charcoal briquettes from coffee grounds, which would reduce waste and create value from the waste materials.
