A Study on the Effect of Rice Husk Charcoal Mix on Coal Briquettes Using the Carbonization Method with Tapioca Flour Adhesive
Year: 2025
Type: conference-paper
Abstract: There are many coal mining companies in Tanah Bumbu Regency, South Kalimantan. The residue of the processing and testing of coal is mostly left by the company so that it is just wasted. This coal can be used to make briquettes. However, coal briquettes are often difficult to ignite and produce a lot of ash. Mixing residual coal with rice husks is desirable because it can improve its characteristics. Rice husks are found in this area because apart from industrial areas, there are also large agricultural areas. Furthermore, rice husks and coal residues are not widely used although it can be used to produce alternative energy fuels. The research method used is experimental quantitative. Coal is pulverized to 18 mesh. Rice husk is carbonized to obtain husk charcoal which is then used as a coal mixing material in making briquettes with tapioca flour adhesive. The results showed that BT-01 briquettes with a composition of 75% coal and 25% husks had the highest heating value 5194 cal/g and longer burning time was 28 minutes, ash content was 17.08%, and inherent moisture was 7.11%. The results of this study are applicable for further use for households and medium-sized industries.
