Organic temple waste has the potential to be used as biomass-based fuel, with a 90% composition of biodegradable waste consisting of leaves, flowers, fruit, and food scraps. To minimize environmental impact, proper management efforts are necessary to handle the temple waste and produce a valuable product. An alternative method for dealing with organic waste include producing fuel from biomass which is refuse derived fuel (RDF). This would not only create a new product for waste wages but also prevent them from ending up as waste in the landfill. The current research aims to investigate the characteristics of organic temple waste and coconut fiber as RDF material and its potential to replace coal use. The RDF was produced from temple waste using leaf and flower components combined with coconut fiber as the primary ingredients. The material was dried, grinded, and produce into powder form before its analyzed by its characteristic. RDF made from temple waste has best result among coconut fibre and the both mixture with above 4800 kcal / kg. It is belonged to class 2 solid fuels based on their characteristics according to the National Standard for biomass-based fuel. Furthermore, the RDF is still needs to be improved for industrial scale and requirement. Product durability test has shown good result for the temple waste material comparing with coconut fibre and coal. The study shown that temple waste and coconut fibre is promisingly to be proceed into RDF as coal substitution in combustion process.
