Abstract

Cassava peel waste in large quantities can harm the environment. Cassava peel waste can be used as a renewable energy feedstock since it is environmentally friendly biomass converted into bio briquettes for use as an alternative fuel. The advantage of cassava peel can positively impact the environment while also adding value to the cassava peel. Cassava bio briquettes produced with water hyacinth and banana leaf stem were compared in this study. Temperatures of 300°C, 350°C, 400°C, 450°C, and 500°C are used to discover the best conditions for briquettes, with a carbonization time of 45 minutes. Bio briquettes can be made from water hyacinth and banana leaf stalks, according to the analysis. The best results were achieved at 400°C carbonization temperature, with a calorific value of 5461 Cal/g for water hyacinth adhesives and 5265 Cal/g for banana leaf stalk adhesives.

Abstract

Isolation is a separator between conductors in electrical equipment that prevents flashover, resulting in a short circuit or electrical failure. Isolation is critical in electrical appliances, exceptionally High Voltage Power Equipment (HVPE), to ensure the safety of circuit breakers, capacitors, and transformers. In addition to being an isolator, the insulating liquid material also serves to cool the heat generated by electrical appliances. Isolator with mineral oil-based transformer has various environmental issues, including non-biodegradability, non-renewability, and rarity. Because it is environmentally safe and extensively used, virgin coconut oil (VCO) is an alternative transformer oil insulation. This study aims to determine the properties of Virgin Coconut Oil (VCO) breakdown voltage using the IEC 156 standard and oil temperature conditioning. According to the test results, the oil breakdown voltage before heating (at room temperature) is 14 kV, which is much below the IEC 156 standard, and the breakdown voltage after heating at 90 ° is 35 kV, and 110 ° is 40 kV, which is even higher than the IEC 156 requirement

Abstract

An autonomous vehicle's primary function is detecting and tracking the road course precisely and correctly without a driver's assistance. As a result, implementing appropriate controllers is critical for improving the vehicle's stability and movement responsiveness. The performance of adaptive Stanley controlled is evaluated in this paper using numerical simulations. The Stanley controller's most common geometric controller for vehicle path tracking algorithms is compared based on their trajectory tracking analyses on various vehicle speed maneuvers. Stanley calculates steering based on the difference between the vehicle's lateral position and heading angle. The difference between desired coordinates and present coordinates of the vehicle along the path is used to calculate lateral, longitudinal, and vehicle heading orientation angle using the future prediction control technique. The results demonstrate that the Stanley controller outperforms the emergency trajectory with more consistent trajectory tracking and steady-state error.

Abstract

Formula Society of Automotive Engineers (FSAE) is a competition where the students design, build, and race the formula-style car. In this competition, the regulation stringent for the safety of participants. Chassis is one of the regulated parts among the other parts. This paper examines design process followed by chassis analysis by using Solidworks 2018 and Abaqus/CAE 6.14 software. The analysis process is carried out with Static Vertical Test, Torsional Stiffness Test, and Crash Impact Test using a safety standard in the form of a safety factor that must be more than 1 (SF> 1) to ensure the safety of the driver. The aim is to obtain an optimum final design based on FSAE Japan regulation as a reference for the Universitas Sriwijaya electric car team, namely Sriwijaya Eco in making the framework for the upcoming electric formula car.

Abstract

Installing a catalytic converter in the exhaust is a typical method of reducing engine exhaust emissions. Catalytic converters have been shown to lower exhaust pollutants while enhancing engine performance. The influence of the number of brass catalyst plates (Cu-Zn) on the Performance of the commercial Yamaha Jupiter MX motorcycle engine manufactured in 2007 was investigated in this study. The catalyst is installed in the motorbike exhaust, with the number of catalyst plates varying between 5 and 8, and a conventional uncatalyzed exhaust serving as a comparison. Torque, power, specific fuel consumption, and thermal efficiency are among the performance factors that will be considered. A prony brake dynamometer was used to conduct torque and power measurements. The results indicate that exhaust with eight catalyst plates can improve engine performance more than an exhaust with five catalyst plates. Furthermore, exhausts equipped with eight catalyst plates can boost engine efficiency by an average of 17.65%. Thus, increasing the number of catalyst brass plates improves the machine's efficiency.
