Characteristics of charcoal briquettes corn cobs charcoal with the addition of areca peel charcoal

Abstract

Corn cobs and areca peel are biomass waste that can be used in the form of charcoal briquettes as an alternative source of energy because they contain lignin and cellulose. The purpose of this research was the best obtain character briquettes from a combination corn cobs charcoal and areca peel charcoal. This research used complete randomized design with 5 treatment and 3 replications. Data were statically analyzed by analysis of variance (ANOVA). The treatments in this research include ratio of corn cobs charcoal and areca peel charcoal 90:10, 80:20, 70:30, 60:40, and 50:50. The result of analysis showed that the ratio of corn cobs charcoal and areca peel affect on density, water content, fix carbon content, ash content but did not significantly affected calorific value. The best treatment briquettes was (90:10) with density content 0,66 g/cm3, water content 4,23%, volatile matter content 15,01%, ash content 3,68%, fixed carbon content 77,07% and calorific value of 6528,73 cal/g.
