Abstract

The Indonesian government recognizes the importance of transitioning away from dependence on fossil fuels. Briquettes are becoming the most popular option for overcoming fossil fuel dependence. This study examines the effect of the drying process and variation of anthracite mixture with wood sawdust on ash content and volatile matter in briquettes. The study used a factorial method with three process variables: water and molasses fractions, temperature, and holding time. The results showed that the highest ash content was obtained in briquettes with a water and molasses fraction of 1:1, while the lowest ash content was at a fraction of 2:1. The temperature and drying time also affected the ash content, where lower temperature and longer drying time resulted in lower ash content. Regarding volatile matter, briquettes with a drying temperature of 120°C and a drying time of 60 minutes produced the lowest volatile matter content. This study concludes that combining the drying process and the right mix of ingredients can improve the quality of briquettes, although the results obtained have not met the established SNI standards.

Abstract

Indonesia is a country rich in natural resources, particularly coal and coconuts. The purpose of this research is to determine the effect of drying processes and the addition of coconut shell biomass to anthracite briquettes on volatile matter content and ash content. A full factorial method was employed in this study, with three factors: drying temperature, drying time, and water-to-molasses ratio. The results show that the coconut shell biomass added to anthracite briquettes significantly affects the volatile matter content. The lowest volatile matter content, 24.8%, was observed in briquette samples dried at 120? for 90 minutes with a water-to-molasses ratio of 4:3. On the other hand, the highest volatile matter content, 28.1%, was produced by briquette samples dried at 100? for 90 minutes with a water-to-molasses ratio of 4:1. The lowest ash content, 41.1%, was found in briquette samples dried at 120? for 60 minutes with a binder ratio of 4:1, while the highest ash content, 35.8%, was observed in samples dried at 100? for 60 minutes with a binder ratio of 4:3.
