<![CDATA[The design and construction of a prototype for a Wind Power Plant (PLTB) using a three-blade Archimedes wind turbine has been completed. This turbine utilizes a DC motor that has been converted into a DC generator, with overall dimensions of 120 x 80 x 80 cm, powered by wind energy. Testing was conducted to evaluate the efficiency of converting wind energy into electrical energy based on various wind speeds and types of loads, including resistors, DC motors, and LED lamps. Test results indicate that system efficiency varies depending on wind speed and load characteristics. The highest efficiency was achieved at an optimal wind speed, ranging from 60-80%, with a power coefficient between 0.1033 and 0.1699. For a 15-watt LED lamp load, the average voltage recorded was 7.404 V, whereas, for a 5-watt DC motor load, the average voltage reached 10.132 V. The testing also revealed that the highest power value for resistor loads was obtained with a 10.5 Ω resistor, delivering 2.22 W. This study highlights the importance of optimizing turbine and generator system design to enhance energy conversion efficiency under varying wind speed conditions.]]>
