The Effect of Bentonite Addition on Briquettes Quality of Corn Cob and Teak Leaf Mixture

Abstract

The effect of adding bentonite to the quality of briquettes from a mixture of corn cobs and teak leaves in this study produced briquettes that met the standards as an alternative fuel. In this research, drying, carbonization, milling, mixing, printing and drying were carried out. The briquettes that have been made are then tested to determine the chemical and mechanical characteristics. The tests applied were tests for water content, ash content, volatile content, carbon content and compressive strength. Variations used in this study by adding bentonite to influence the quality of the briquettes made, variations in the addition of bentonite were carried out 4 trials with 0%, 10%, 20%, 30%, 40%. With each study testing the water content, ash content, volatile content, carbon content and compressive strength. The highest results obtained from testing the water content were from the 40% bentonite variation of 13.03% and the lowest water without bentonite was 10.79%, the highest ash content was at 40% bentonite at 22.41% and the lowest ash content without bentonite was 4. .86%, the highest volatile content was in 10% bentonite at 32.22% and the lowest at 20% bentonite at 25.29%, the highest carbon content was in the treatment without 0% bentonite at 55.78% and the lowest at 40% bentonite at 36, 16%, the highest compressive strength was in the 40% bentonite variation of 135.82(N/cm2) and the lowest compressive strength was in the treatment without 0% bentonite of 39.79(N/cm2). The quality of the briquettes made in this study did not meet the standards (SNI 01-6235-2000) for water content, volatile content and bound carbon content
