Characterization of charcoal briquettes made from rubber rods and coconut shells with tapioca as an adhesive.

Abstract

Briquettes are biomass used as alternative household energy to replace LPG. One of the materials for making briquettes is rubber rods and coconut shells because they contain cellulose and lignin. The goal of this study is to combine raw materials for rubber rods and coconut shells with high-quality tapioca adhesive in order to produce charcoal briquettes with the best properties in accordance with SNI No. 01-6235-2000. In this study, five treatments of three tests were used in a completely randomized design. Rubber rods and coconut shell charcoal were used in this study’s treatment in ratios of 90:10, 80:20, 70:30, 60:40, and 50:50. The briquette analysis results show that the briquette treatment comparison affects the test of water content value, ash content, evaporating substance content, bound carbon, and calorific value. BKTK5 treatment is a 50/50 blend of rubber rod charcoal and coconut shell charcoal with the same weight as charcoal (23.75 g). BKTK5 is the best treatment, with a water content value of 4.87%, an ash content value of 3.56%, an evaporating substance content value of 4.76%, a bound carbon value of 86.81%, and a calorific value of 8082.29 cal / g.
