Abstract
Now days, renewable energy is always being the interest thing to be studied, one of the examples of friendly environment renewable energy is briquette. In this study canary shell and coal were being the main materials for briquetting that would be made because canary shell assessed has high calorific value and not much cultivated and suitable to combine with coal to increase the calorific value, thus the beneficiation of canary shell as a mixture of coal briquette is being the purpose of this study. Research methods of this study were coal and canary shell carbonation grinded being the size 28 mesh, 65 mesh and 80 mesh, then conducted briquetting process with the starch and water as glue with the composition 125 gr: 25 gr: 50 ml and every size consist of four kinds of briquettes that are 100% canary shell, 100% coal, 50% canary: 50% coal and 75% canary: 25% coal. Those samples were analyzed the proximate contents, sulfur content and calorific value to find their quality. The result of this study shows that on proximate analysis, the concentrations of moisture, ash, volatile matter and fixed carbon of briquettes are varies greatly while on total sulfur analysis, the highest concentrations are dominated by 100% coal and the lowest are 100% canary in all sizes. Meanwhile on the calorific analysis, the briquettes with the size 65 mesh in all compositions are having higher concentrations than size 28 and 80 mesh which is from four kinds of those briquettes, the highest calorific value is 100% canary with a concentration is 6354 cal/gr and the lowest is 100% coal with a concentration is 5539 cal/gr) while for the mixing of canary and coal 50:50% is 6020 cal/gr and 75:25% is 6096 cal/gr.
