Abstract

The fossil fuel crisis in Indonesia, which contributes 85% of the national energy mix, has driven the need to utilize renewable energy sources, one of which is exhaust wind as industrial waste energy that has high speed (5-7 m/s) and good flow continuity. This study developed a vertical Savonius turbine with variations in exhaust-turbine distance (20, 30, 40 cm) and measured wind speed (5.3, 6, 6.4 m/s) to optimize the utilization of this energy. The results showed that the 20 cm configuration produced the best performance with a maximum power of 5.98 watts at a speed of 6.4 m/s and a Coefficient Performance (CP) of 0.16, which is 31% more efficient than a distance of 40 cm, proving the potential of exhaust wind as a renewable energy solution that is applicable in industry with a payback period of less than 3 years and the potential for reducing the load on the electricity network by up to 15%.

Abstract

Abstract. Two-wheeled vehicles, namely motorbikes, are still the mainstay as an affordable means of transportation for the majority of Indonesian people. Motorcycles are a means of transportation that are often found, both in urban and rural areas. Motorcycles have many advantages compared to other means of transportation Tires are an important part of land vehicles, tire conditions that are not in accordance with the standards can cause tire bursts which result in traffic accidents. Frictional forces that occur in the tires can cause wear on the tires. Various factors that affect wear include the speed of movement and the amount of load. In this study an analysis was carried out to find out how the effect of load and speed on the resulting frictional cross-sectional area. The analytical method used in this study is Kruskall-Wallis and Mann-Whitney. Penelitian ini menghasilkan kesimpulan bahwa faktor beban memiliki pengaruh yang signifikan terhadap penampang gesekan ban sepeda motor pada lintasan beton. Sedangkan perlakuan atau faktor kecepatan tidak memiliki pengaruh yang signifikan terhadap penampang gesekan ban sepeda motor pada lintasan beton.

Abstract

The metal coating process plays an important role in improving the corrosion resistance and service life of products. One of its main components is the main pot, a refractory container that holds aluminum, zinc, and silicon alloys at high temperatures. The temperature stability of the coating fluid is highly dependent on the performance of the inductor as the main heat source. The problem encountered is that the inductor's capacity is not yet optimal in maintaining the operating temperature, thereby affecting the efficiency of the process and the quality of the coating results. This study aims to analyze the inductor's ability to maintain the main pot temperature, identify factors that affect heating efficiency, and provide recommendations for improving system performance. The methods used include measuring the liquid temperature, recording electrical power, and observing the decrease in coating volume. The results show that four inductors with a total capacity of 1800 kVA only meet about 20–23% of the energy requirements. The fluid temperature can be maintained in the range of 602–608 °C, but tends to decrease over time. The coating volume decreased by an average of 8.05–11.61% during five hours of operation. Increased power capacity and a periodic refill strategy are needed to maintain temperature stability and coating efficiency.

Abstract

The burner in the Continuous Sheet Line (CSL) machine plays a crucial role in generating heat for the steel production process. However, under operational conditions, problems such as explosion and imperfect combustion are often found due to imperfect air-gas ratios. This study aims to analyze the performance of LNG-fueled burners in CSL furnaces, evaluate the influence of Air Flue Ratio (AFR), air and gas distribution on combustion efficiency in each zone, and assess the role of casing materials as insulators on furnace thermal efficiency. The data studied included gas and air pressure, flow rate, furnace temperature, and LNG consumption. Calculations are performed to determine gas flow, airflow, Qinput, Qthermal, AFR, and burner efficiency in each zone (H2-D and H2-W). In addition, thermal analysis was performed on various insulating materials such as ceramic fiberboard, calcium silicate, and micropore silica to assess their effect on heat loss due to conduction and radiation. The results show that burner efficiency is not always directly proportional to the theoretical AFR value. In the H2-D zone with a relatively high AFR (12.55–15.56), the efficiency reached 69%–82%, while in the H2-W zone with a lower AFR (10.86–11.96) the efficiency decreased to 59%–63%. In addition, in some zones such as zones 1, 7, and 8, there is an aberration of the air-gas ratio from the ideal value, with the average airflow being lower than the theoretical standard. From the thermal side, the use of insulation materials with low conductivity such as microporous silica is able to reduce heat loss by more than 80% compared to standard materials. Increased insulation thickness has also been shown to reduce heat loss by up to 50%, especially in areas with high heat exposure.
