Abstract
There is a lot of banana skin waste in Palu city every day and it is only transported to a landfill. One alternative to reduce banana peel waste is to use this waste as a material for making charcoal briquettes. This study aims to make and measure the characteristic parameters of the resulting banana peel briquette charcoal. The stages of making charcoal briquettes are collecting raw materials, drying raw materials, carbonization, mashing, sieving, mixing adhesive materials, printing, drying and determining the characteristics of briquettes. Variations in the composition of banana peels and tapioca starch adhesives in this study were: 90%:10%, 85%:15%, and 80%:20%. The results of testing the characteristics of briquettes on density obtained values ranging from 0.463 gr/cm3 - 0.5662 g/cm3, compressive strength ranging from 21.9588-32.6662 kg/cm2, moisture content ranging from 3.6451-6.4464%, ash content ranged from 16.736-17.930%, volatile matter content ranged from 58.474-60.873%, bound carbon content ranged from 14.7512-21.1449%, and heating value ranged from 7406.846-9864.683 cal/g and burning rate of 0.14 gr/sec. variations in composition with the best characteristic test results that meet several Indonesian National Standards (SNI), namely at a ratio of 85%:15%. Banana peels can be used as a raw material for making charcoal briquettes and produce heat energy as an energy source
