Abstract

This research was conducted to utilize coconut shell waste in the community by processing it into briquettes. The purpose of this study was to determine the quality of coconut shell charcoal briquettes that are good for use as an alternative fuel. Limitation of the problem in this study is starch and sago flour with a composition ratio of 90:10. Pressing pressure used is 2000 kg/cm2. Drying temperature is 100° C using solar heat for 3 days. Carbonization temperature is 500° C. Coconut shell is 1 kg, the adhesive ratio is 100 grams/0.2 liters of water and does not use a coating. The method used in this study is the method of pyrolysis with the combustion process using a closed furnace and sifting using a sieve with a size of 40-60 mesh. Furthermore, testing the quality of the briquettes are briquette water content (%), ash briquette content (%), volatile matters (%), fixed carbon content (%), measurement of density (g/cm2) ), specific gravity (kg/m3), measurement of combustion rate (gr/min) and compressive firmness (kg/cm2). The results of testing the quality of coconut shell charcoal briquettes obtained the average value of water content is 3.42%, the average value of ash content is 3.318%, the average value of the vaporizer content is 3.31%, the average value of bound carbon content is 93.37%, the average value of density is 1.55 g/cm3, the average value of specific gravity is 1.52 × 10-6 kg/ m2.s2, the average value of combustion rate is 0.342 g/cm2, the average compressive strength value is 761.5 N/m2.
