Abstract

Turbines are a key component in hydroelectric power generation, including the Archimedes Screw type, which is specifically designed to operate under low head and low water discharge conditions. This study aims to calculate the rotational speed of the Archimedes Screw turbine under varying water discharge rates, analyze the effect of discharge on turbine rotation, and compute and evaluate the turbine’s efficiency. A quantitative experimental approach was employed, with data obtained through direct testing of a designed Archimedes Screw turbine prototype. Research instruments included measurements of turbine rotational speed and the generated electrical power. Tests were conducted three times at a 45° inclination angle. The results showed that the actual power (Pactual) generated was 11.95 Watts in the first trial, 10.96 Watts in the second, and 12.56 Watts in the third. These findings indicate variations in power output influenced by water discharge and demonstrate the potential of the Archimedes Screw turbine as a micro-hydro energy solution for low-flow water sources. The study concludes that optimizing design and operational parameters is essential for improving the efficiency of such power generation systems.

Abstract

A stable room temperature is essential for comfort. This study tests the performance of split wall air conditioners with R-22 refrigerant and evaluates how to improve their efficiency through the influence of cooling air temperature. The experiment was carried out by varying the air temperature and cooling load using a heater. Data is taken every 15 minutes for 2 hours using a digital thermometer. The results showed that the maximum coefficient of performance (COP) value reached 8 indoors and 7.2 outdoors. Meanwhile, the maximum energy efficiency ratio (EER) value was recorded at 4.2 indoors and 3.7 outdoors. The stability of COP and EER values indicates that the Split Air Conditioner can operate efficiently despite variations in air temperature and cooling load. Cooler cooling air proved to be crucial in improving system efficiency. Conversely, higher refrigerant loads tend to decrease efficiency. However, this drop can be minimized by keeping the cooling air temperature low. The selection of the appropriate refrigerant, such as R-22, also plays an important role in supporting optimal performance. The combination of cooler cooling air and the right refrigerant allows the split air conditioner to operate with high efficiency. This research provides an important basis for the development of energy-efficient and efficient cooling systems. Optimizing the temperature of the cooling air is one of the main keys in improving the efficiency of the cooling system. With the right approach, split air conditioners can be used more effectively to create thermal comfort while saving energy.

Abstract

Water has a very important role in everyday life. Apart from humans, other living things also depend on water to survive. But there are still many areas in the world even in Indonesia still experiencing drought or clean water crisis. Therefore, new innovations are needed in producing water. One of the innovations is the atmospheric water generator (AWG) which utilizes the formation of water from air or condensation. The AWG in this research uses thermoelectricity as a cold source. Where thermoelectricity is less noisy, easy to obtain and assemble into a system, has a long service life without requiring maintenance. But thermoelectrics have disadvantages where cooling on thermoelectrics is less efficient. So to overcome this, I as the author use a hydrophobic surface as a condensation surface where it can accelerate condensation and increase the amount of water produced. In this study to see the comparison, tests were carried out using various types and surface areas.

Abstract

Indonesia is a tropical country that has great potential for harnessing and managing solar energy. At present, the technology of converting solar energy into electrical energy such as solar cells still has weaknesses in terms of cost. Therefore, this study aims to test the potential of solar energy by creating a solar home system plant using DVD and Zener diode. This solar home system plant using DVD has the advantage of using low cost and the power generated can be said to be sufficient. In addition, this product can be used as a substitute for solar cells if properly applied. This study uses an experimental method in a quantitative approach. In this study, the independent variable is the structure of the solar panel while the dependent variable is the amount of energy read by the voltmeter. This study uses the photoelectric principle. Where photoelectricity is an electron released from the surface of an object exposed to light. This study was carried out by looking at how much power could be generated by DVD and Zener diode. The results showed that DVD and Zener diode can generate electrical energy, but the results are still too small and a large number of DVDs are needed to generate more energy. So it can be concluded that DVD still cannot replace solar panels, but can be used as a tool to maintain the stability of solar panels.
