Abstract

Coconut shells and corn cobs are types of agricultural waste that have economic value to be converted into alternative energy, namely briquettes. The purpose of this research was to determine the effect of variations in raw materials on the characteristics of charcoal briquettes mixed with coconut shell and corn cobs. In the research the percentage of variation that will be used is 30% coconut shell mixed with 70% corn cobs, 50% coconut shell mixed with 50% corn cob, 70% coconut shell mixed with 30% corn cob. The variations in the load used to press the briquettes are 1kg, 3kg, and 5kg, each variation of the briquettes will be pressured by a load of 1kg, 3kg, and 5kg. In the mass reduction test, it is carried out directly on a digital scale and observations are made every minute. The endurance test was carried out by dropping the briquettes from a height of 2m. Meanwhile, the calorific value was tested using a bomb calorimeter. From this study, the best resistance of briquettes was obtained in the variation of 70% coconut shell mixed with 30% corn cobs and given a load of 5 kg with a resistance percentage of 99.58%. The best density value occurred in the variation of 30% coconut shell mixed with 70% corn cobs and given a load of 5 kg with a value of 0.576 gr/cm3. The best calorific value was obtained in the variation of 70% coconut shell mixed with 30% corn cobs and given a load of 5 kg with a calorific value of 7632.45 cal/gr.
