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.

Abstract

One of the leading exports in Indonesia is coal and contributes significantly to the country's economy. However, there is coal that cannot be exported because it has a size dimension that is too small, therefore research is carried out to make briquettes. The purpose of this research is to get the best results from testing volatile matter and ash content with different temperatures, times, water:molasses fractions. The highest volatile matter test results were obtained from 100 ? temperature, 90 minutes time and water:molasses fraction (3:1) with a value of 31.73% and the lowest value was obtained from 120 ? temperature, 60 minutes time and water:molasses fraction (3:1) with a value of 23%. While the highest ash content test results were obtained from a drying temperature of 120 ?, time 90 minutes and water:molasses fraction (3:2) with a value of 48.6% and the lowest value was obtained from a drying temperature of 100 ?, time 60 minutes and water:molasses fraction (3:2) with a value of 41.83%. From the test results of volatile matter and ash content, it still does not meet SNI standards.

Abstract

The Bangka Belitung Islands consist of two main islands, namely Bangka Island and Belitung Island, which have abundant marine natural resource potential. One of the typical products of the seafood is Kericu, which is a snack made from squid eggs and sago. Kericu has become a special souvenir that is in demand and has become a home-based business opportunity. UMKM "Ampiang Yu Erin" is one of the producers of keriku whose manufacture is still using manual methods, which causes obstacles in terms of worker fatigue and product inconsistencies. To overcome this problem, modifications to the crevice forming machine are carried out to improve production efficiency and product uniformity. Although the desired results have not yet been fully achieved, the trial showed progress close to the expected crease shape, confirming the importance of the mold in influencing the final quality of the product. The Bangka Belitung Islands consist of two main islands, namely Bangka Island and Belitung Island, which have abundant marine natural resource potential.

Abstract

The increasing dependence on fossil fuels drives the need for alternative energy solutions to reduce environmental impacts and reliance on petroleum. Coal, particularly anthracite, has emerged as one of the best options due to its abundant availability in Indonesia. However, coal combustion often results in the emission of harmful gases, requiring special handling. This study aims to develop coal briquettes using lime water as a binder. In addition to improving the mechanical characteristics of the briquettes, lime water is also intended to reduce sulfur gas emissions during the briquette combustion process. The briquettes were produced using a binder-to-water ratio (5:6, 5:7, 5:8, 5:9), pressing pressure (8, 9, 10 tons), and drying time (2, 4, 6 days). Compression testing was conducted following the ISO 844 standard using a Universal Testing Machine. The highest result in this study was 502 kPa (5.11 kg/cm²), achieved with a binder-to-water ratio of 5:9, a pressing pressure of 8 tons, and a drying time of 4 days. However, this result remains far below the SNI standard (50 kg/cm²).
