Utilization Of Religious Offering Waste (Canang) As A Raw Material For Briquettes As An Environmentally Friendly Alternative Energy Source

Abstract

Canang waste, a type of organic waste from Balinese Hindu offerings, is commonly produced in traditional villages such as Desa Tihingan. This study aims to utilize canang waste as raw material for briquette production. The method employed is experimental, involving stages such as material collection, drying, shredding, carbonization, sieving, mixing, molding, and drying. Samples were tested using a bomb calorimeter to determine their Higher Heating Value (HHV) and Lower Heating Value (LHV). The results showed that canang briquettes have an HHV of 21.27 MJ/kg and an LHV of 19.64 MJ/kg, which are higher than those of mixed organic briquettes (HHV: 20.62 MJ/kg, LHV: 18.47 MJ/kg), but lower than prapen charcoal (HHV: 26.95 MJ/kg, LHV: 25.82 MJ/kg). These findings indicate that canang briquettes have potential as a viable alternative fuel. Moreover, this approach offers an environmentally friendly and sustainable solution for managing ceremonial waste.
