The Effect of Adhesive Ratio on the Quality of Charcoal Briquettes

Abstract

This study used cassava stem charcoal and charcoal from forest fires mixed with tapioca adhesive at different ratios, the aim was to analyze the effect of different adhesive ratios on the quality of charcoal briquettes.Charcoal briquettes are formed using a 40 bar press machine with a pressing time of 10 minutes. The mixture of charcoal briquette raw materials uses a tapioca adhesive ratio of 2%, 4%, 6%, 8% and 10%.Testing is carried out to determine the quality, then analyzed and compared with the SNI 01-6235-2000 standard.The effect of adhesive ratio on adhesive quality was analyzed using a Completely Randomized Design (CRD). The test results show the following values:density 0.54 g/cm³, moisture content 4.97%, compressive strength 28.43 kg/cm², volatile matter content 36.02%, ash content 6.36%, fixed carbon content 56.45% and calorific value 6,195 cal/gobtained from a 10% adhesive ratio. The adhesive ratio has a very significant effect on the water content, compressive strength and calorific value; has a significant effect on the density value; and has no significant effect on the volatile matter value, ash content and bound carbon content.The results of charcoal briquette testing mostly meet the standards according to SNI (No. 01-6235-2000)
