Abstract

This research aims to design and build a Darrieus wind turbine with three blades on a laboratory scale. The Darrieus wind turbine was chosen because of its efficient design in utilizing wind speed to produce mechanical energy. The research methodology involves several stages, starting from designing turbine blades that use PVC pipes that are heated and formed into flat plates, to designing turbine frames from hollow iron and iron plates. The blade and frame design is optimized to ensure stable and efficient turbine rotation. The turbine is equipped with a washing machine dynamo to increase rotational stability compared to using a fillow block. The research results show that the Darrieus turbine design with three blades is capable of producing stable and efficient rotation. The rotation speed of the turbine is influenced by wind speed, blade area, and blade curve length. Apart from that, the height between the frame and blades also affects the stability of the rotation. The design calculation results show that the turbine sweep area is 24617 m² with a wind speed of 3 m/s resulting in a tip speed ratio of 5 and a turbine rotation speed of 15 m/s. The conclusion of this research is that the Darrieus wind turbine with three blades can function well on a laboratory scale. Proper blade and frame design is critical to achieving stable and efficient rotation. This turbine has the potential to be further developed as a renewable energy solution in Indonesia.

Abstract

This research aims to evaluate energy distribution in vertical energy saving devices in order to improve patented products. The method used includes measuring air flow speed, temperature and enthalpy at several points using an anemometer and digital thermometer. The fuel used is firewood, and the tool is tested with the help of an exhaust fan to draw in combustion gases. The test results show that the heat from the coal stove can be used to dry commodities placed on the shelves above, resulting in energy savings. The average speed of air flow at the exhaust site is 610 m/s, while the average outside air temperature is 285°C and the average exhaust air temperature is 591.4°C. Data analysis shows that the enthalpy values from the kiln to the disposal are irregular due to the inconsistent quality of the charcoal. Apart from that, there is wild air coming in through doors that are not tight enough. The conclusion of this research is that the use of vertical energy saving devices can save heat from coal stoves by utilizing this heat for drying other commodities. However, improvements need to be made to the tool design to reduce stray air entering and increase the consistency of combustion results.

Abstract

This study explores the utilization of photovoltaic solar panels as a source of electrical energy to meet the needs in hard-to-reach areas. Using experimental methods, data were collected during observations from September 13 to September 18, 2024, encompassing measurements of voltage, current, and solar radiation intensity. The results indicate that the highest panel efficiency reached 25.12%, while the lowest was 19.25%, significantly influenced by sunlight intensity and panel temperature. Additionally, the highest convective heat transfer coefficient was recorded for Panel 1 at 96.64 W/m²K, showing a direct relationship with thermal conditions. This research emphasizes the importance of system design and the management of environmental factors to enhance panel efficiency. These findings open opportunities for the development of cooling technologies and more efficient energy conversion in the future.

Abstract

This study evaluates the impact of RON 90 and RON 92 fuels on the performance of a 4-stroke engine with a capacity of 2800 Watts. In the applied methodology, a 2800 Watt two-wheeler vehicle was used to test torque, power, and specific fuel consumption (SFC) at various engine speeds. The results show that RON 92 has better torque at 4000 RPM, while RON 90 exhibits higher torque at speeds approaching 7500 RPM. Power analysis indicates that both fuels produce the same maximum power of 8.7 HP, although it is achieved at different engine speeds. Meanwhile, in terms of SFC, RON 92 is more efficient at lower speeds, but the difference narrows at higher speeds. These findings provide insights into the performance of both types of fuel and their use in engine applications.
