Abstract

The choice of fuel (fuel oil) whose price is higher needs a solution, especially for conventional foundry entrepreneurs. We need alternative energy that is cheap and easy to get. Wood pellets are an attempt to replace fuel with cheap fuel. As with previous studies, the main objective of this study was to measure the energy potential of the smelting furnace flue gas. The analysis results show that 365,413.3 kJ of heat energy is wasted from the total point required for smelting. The flames sometimes coming out of the furnace flue gas channel indicate that some heat energy is smashed into the free air. The exhaust gas temperature is measured at 500-550⁰C, and you can see flashes of fire coming out frequently. This indicates that there is energy potential for the working process of the pyrolysis reactor; apart from that, the moments of fire that often appear indicate an excess of the combustion process in the furnace. This study's results may differ from other smelting furnace constructions and conditions.

Abstract

Recycling process of the plastic waste into fuel in the concept of Waste to Energy is a technology that began to popularize the pyrolysis method. In addition to liquid fuels as the main product , which is produced from the above method is solid and non - condensable gases. Generaly, the residual gas is burned directly , while the solids can be processed into solid fuel (char briquettes) . To process the solids into a char ( fixed carbon + ash ) then it should be the beginning of a process to remove moisture and reduce levels of volatile matter . Despite a volatile fuel but large levels indicate that the pyrolysis process has not been good , besides the burning application will cause soot . Initial research has resulted in the burning of 8 quality test data sample of 13 samples char briquettes obtained by pyrolysis of polyethylene plastic material with an operating temperature variation between 450-500 ° C , as well as mass variations and types of catalysts Zeolite Y and Natural Zeolite . In addition, the variation was also performed by mixing the PE material with the type of Polystyrene , Polypropylene , Polyethylene Terephthalate , and Other . Char characteristics are known through the proximate test include moisture content , ash , volatile matter and fixed carbon , calorific value is tested through the bomb calorimeter . Combustion quality tested in the furnace at a temperature of 230 ° C ± walls and constant air flow of 0.7 m / s , and the measured emission levels .The problem is in the application note that burning briquettes are not optimized , long heating periods indicated , as well as varying levels of CO . Therefore, it is necessary to the optimization of combustion quality will be analyzed through the ultimate test and the effect of porosity.

Abstract

The need for electricity in Indonesia continues to increase every year and its supply is increasingly limited because most power plants in Indonesia still depend on conventional energy (fossil fuels). Solar power plants (PLTS) are very suitable to be developed in Indonesia because they have abundant sources of solar energy. with an average solar radiation intensity of about 4.8 kWh/m² per day. Therefore, in this study a design of a household-scale solar power plant (Solar Home System) will be made, with the aim of saving electricity and electricity bills from PLN. The power designed in this study is 0.9 kW. Using 3 units of ST Solar 300 Wp solar panels and the Solis On-Grid Mini-1000-4G Inverter. Based on the economic analysis, this design requires an initial capital of Rp. 17,500,000. savings in electricity bills obtained each month is IDR 154,464. and from the results of the BEP calculations that have been carried out, it is known that the capital will return in the 9th month-6th year

Abstract

Engine performance refers to the capability of an internal combustion engine to convert input energy, specifically fuel, into useful power. One method to enhance engine performance is to modify components of the intake system that affect airflow. A turbo insulator, which is a modified gasket connecting the carburetor to the intake manifold, is designed to generate turbulent airflow into the combustion chamber, thus improving combustion efficiency. This study aims to design and evaluate a turbo insulator on the intake manifold of a Suzuki Shogun NR-125 CC motorcycle through experimental testing of its impact on engine performance—specifically torque and power. A descriptive analysis method was employed for data analysis. Engine performance testing was conducted using an engine dynamometer, following ISO 1585 standards, within an engine speed range of 3,000 to 9,000 rpm, under standard factory conditions and with various turbo insulator configurations (5 and 7 blades, 45° and 60° blade angles, 4 mm and 8 mm thicknesses). The results indicate that the turbo insulator improves engine performance. The most optimal configuration, V-5 (5 blades, 45° angle, 8 mm thickness), achieved a maximum torque of 11.27 Nm at 3,500 rpm and a maximum power output of 10 HP at 7,750

Abstract

The global energy crisis and continued reliance on fossil fuels have intensified the search for sustainable alternative energy sources, particularly biomass-derived biofuels. One promising yet underutilized resource is the peel waste of Carica pubescens, a papaya variety indigenous to the Dieng Plateau. This study investigates the potential of Carica peel waste as a bioethanol feedstock through sulfuric acid (H₂SO₄) hydrolysis and fermentation using Saccharomyces cerevisiae. To optimize sugar yield, the concentration of H₂SO₄ was varied between 0.1 M and 0.8 M, while fermentation durations were set at 96, 120, 144, and 168 hours. Results indicated that hydrolysis with 0.8 M H₂SO₄ produced the highest sugar concentration (6.8%). The most effective fermentation period was 120 hours, yielding 64% bioethanol with a density of 0.8679 g/mL, a calorific value of 4,831 kcal/kg, a flame height of 14.6 cm, and a combustion temperature of 438°C. These findings demonstrate the viability of Carica peel waste as a valuable raw material for bioethanol production. Its high efficiency and favorable fuel properties highlight its potential for integration into local renewable energy initiatives, contributing to sustainable energy development. Further studies on large-scale implementation and process optimization are recommended to maximize its industrial application.
