PENGARUH KOMPOSISI DAN UKURAN PARTIKEL TERHADAP KUALITAS BRIKET KULIT DURIAN DAN TEMPURUNG KELAPA

Abstract

Research has been carried out on the utilization of durian rind and coconut shell waste by turning it into bio briquette. This study aims to determine the amount of heat, water content and duration of combustion to obtain the best quality. Samples were made with the composition of durian rind, coconut shell, and tapioca flour as an adhesive. Each sample was carbonized with a combustion drum and furnished at a temperature of 250ºC, then grinding, sifting, and moulding was carried out. The composition variations used are (20:80)%, (40:60)%, (60:40)%, and (80:20)% with particle sizes of 100 mesh and 170 mesh, the gelatinous mass used is 3 gr. The results of the study, testing the calorific value using the bomb calorimeter obtained the best quality in the composition (80:20)% with a size of 100 mesh of 6482,76 cal/gr, the results of testing the moisture content using a 105ºC oven obtained the best quality in the composition (80:20)% with a 100 mesh size of 6,77% and the most extended burning test with duration in composition (20:80)% with a 170 mesh size of 211,8 minutes/gr
