STUDY OF THERMAL PROPERTISE OF BRIQUETTE CHARCOAL FROM MOTHONG DURIAN SHELL

Abstract

This research studied the ability of using Monthong durian shell as a fuel for heat energy in the form of briquette charcoal by using tapioca starch as a binder. Extrusion by cold compression the results showed that the charcoal ratio from Monthong durian shell and tapioca starch was 97:3 by weight, after drying, met the general characteristics of the community product standard. From the test, it was found that the moisture content of 5.60% by weight, ash content 6.4% by weight, the heat value of 5,735 calories per gram. Which according to the community product standard, the moisture content is not more than 8% by weight, the ash content is not more than 8% by weight, the heat value is not less than 5,000 calories per gram. From the results of the study, it was found that Monthong durian shell could be used to produce charcoal briquettes for use in heating energy.
