Blending Batubara Dengan Limbah Biomassa Tongkol Jagung Untuk Mengurangi Ketergantungan Sumber Energi Tidak Terbarukan

Coal reserves as a non-renewable energy resource are running low. To reduce the coal consumption, the present study carried out blending of coal and renewable energy resource from biomass such as corncob. In this study, we observed the effect of blending ratios of corncob to coal in order to establish the recommended blending ratio that meets the requirement of the industry and power plant. The quality parameters observed from the mixture of coal and corncob were calorific value and sulfur content. The coal used in this research has the heating value of 8403 cal / gram and the sulfur content of 0.71%. Meanwhile, the corncob has the calorific value of 3409.64 cal / gram and the sulfur content of 0.14%. The results showed that the best blending ratio of corncob to coal was 75%,
