PRODUCTION OF DURIAN PEEL BRIQUETTES (DURIO ZIBETHINUS MURR) USING VARIATION IN CARBONIZATION TEMPERATURE AND WEIGHT RATIO OF CLAY ADHESIVE TO USED WASTE COOKING OIL

Abstract

Briquettes are an alternative fuel to replace the use of fossil fuels. The use of durian peel as a raw material for briquettes helps to reduce waste while providing economic added value. Clay that hardens when dry and sticky when mixed with water, so it can be used as an adhesive on briquettes. Used cooking oil is a waste that is used as an additional binder and increases the calorific value of the briquettes. This study aims to examine the characteristics of durian peel briquettes with a particle size of 60 mesh, carbonization time of 1 hour, variations in carbonization temperature (400°C, 450°C, and 500°C) and variations in the weight ratio of clay adhesives: used cooking oil (1:2; 1:2,5; 1:3; 1:3,5; 1:4). The results show that the variation in carbonization temperature and adhesive weight ratio significantly affects the characteristics of the briquettes. The most optimal conditions were obtained at a carbonization temperature of 500°C with a variation in the adhesive weight ratio of 1:4 which produced briquettes with a moisture content of 1.667%, ash content of 7.848% and evaporative substances of 3.940%, bound carbon content of 86.545%, and a calorific value of 6495.39 cal/gram which has met the parameters of SNI 01-6235-2000.
