Abstract

Coal quality assessment is crucial for determining its suitability as a fuel for power generation and industrial applications. Such evaluation generally involves proximate and ultimate analyses. The proximate analysis provides information on moisture, volatile matter, fixed carbon, and ash content, whereas the ultimate analysis identifies elemental composition such as carbon, hydrogen, oxygen, nitrogen, and sulfur. Geological factors, including age, temperature, and pressure during formation, strongly influence coal quality. This study aims to evaluate the effect of particle size on coal quality using grain sizes of 40 and 60 mesh, analyzed according to ASTM standard procedures. The results indicate that coal with a grain size of 40 mesh contains, on average, 22.22% moisture, 5.83% ash, 37.54% volatile matter, and 34.15% fixed carbon. In contrast, coal with a grain size of 60 mesh exhibits 20.45% moisture, 6.80% ash, 42.77% volatile matter, and 29.99% fixed carbon. These findings highlight the significant influence of particle size on the proximate characteristics of coal, which can affect its combustion behavior and potential applications in power plants and other industries

Abstract

In crude palm oil production, productivity largely depends on the performance of the sterilizer, particularly the horizontal type that operates using steam pressure. This study aimed to analyze the performance of the sterilizer by observing the boiling process of fresh fruit bunches (FFB) and determining the heat required during a single sterilization cycle. Observations were carried out throughout the sterilization process, with steam pressure monitored using the pressure gauge located on top of the sterilizer vessel. The daily steam requirement varied, with the highest recorded on the 10th day, reaching 1,050 kg of steam for 735 tons of FFB. Interestingly, a higher volume of FFB did not always correspond to a higher steam demand. On average, the sterilization process required 827 kg of steam per ton of FFB over 24 hours. At PT. Perkebunan Nusantara IV PKS Dolok Sinumbah, the horizontal sterilizer operates with a triple-peak system, a boiling time of 90–100 minutes, steam pressure of 2.8–3.2 kg/cm², and temperatures between 120–135 °C. The results indicate that the heat required reached 738,160.5 kcal/s, the latent heat was 7,772,760 kJ, and the total steam consumption amounted to 8,510,920.5 kcal for 30 tons of FFB.

Abstract

The utilization of solar energy as a renewable energy source is becoming increasingly important to reduce dependence on fossil fuels. One of its applications is the parabolic reflector solar cooker, which harnesses solar radiation for cooking purposes. This study aims to evaluate the performance of a solar cooker equipped with a parabolic reflector through a water heating test. The study presents an analysis of the performance of a solar cooker using a parabolic reflector collector. The solar reflector was constructed from mirror fragments arranged to form a parabolic shape with a surface area of 1.05 m². The experiment was conducted in the Lhokseumawe region, Aceh Province, Indonesia, located at coordinates 5°12’11.01’’ N and 97° E, with an altitude of 18.3 m above sea level. Performance measurements were carried out using a water heating method with a vessel containing 3.2 kg of water placed at the focal point of the reflector. The solar radiation received by the collector was reflected toward the focal point, heating the water directly. The results showed that the water temperature increased to 82.4 °C within 60 minutes, from 12:00 to 13:00 local time (WIB). The overall efficiency of the solar cooker was found to be 33.9%. These findings indicate that the parabolic reflector solar cooker has strong potential as an environmentally friendly alternative energy source suitable for application in tropical regions

Abstract

This study aims to evaluate the effect of chimney height variation on the performance of a solar-powered cascara coffee dryer prototype. Chimney height is an important parameter in drying systems because it affects the rate of hot air flow, relative humidity, and drying process efficiency. An experimental study was conducted by varying the chimney height in the dryer's air outlet duct, then observing the drying performance of coffee cherry husks (cascara) as the test material. The main parameters analyzed included drying time, temperature stability in the drying chamber, drying efficiency, and final product quality. The results showed that variations in chimney height had a significant effect on system performance. A chimney with a height of 220 cm proved to produce the best performance with a more stable air flow rate, consistent drying temperature, and 100% efficiency. This results in a faster, more even, and higher quality cascara drying process. The final product, dried cascara coffee, can then be processed into high-value herbal tea drinks and has the potential to increase coffee product diversification. Thus, this study confirms that proper chimney height adjustment is a crucial factor in the design and development of solar drying technology, especially for agricultural products such as coffee cherry skin. These findings are expected to serve as the basis for developing more efficient, environmentally friendly dryer designs that support increased added value for coffee derivative products at both the farmer and small-to-medium industry levels.
