Rancang Bangun Hybrid Turbin Angin-Surya untuk Jalan Tol Menggunakan Savonius Rotor

Abstract

This research focuses on the design and construction of a hybrid wind-solar turbine utilizing a Savonius rotor for application on toll roads. The main objective is to implement and analyze the performance of this renewable energy system within the context of toll road infrastructure. The research methodology includes the design of a system that integrates a vertical Savonius-type wind turbine with a blade diameter of 33 cm and a length of 57 cm, a solar panel, and an Arduino-based control system to stabilize the output voltage. Testing was conducted in a laboratory by varying wind speeds from 2 m/s to 6 m/s and measuring solar light intensity. The test results indicate that the system's performance is significantly influenced by environmental conditions. The no-load output voltage of the wind turbine increased from 2.70 V to 15.13 V as the wind speed increased, while the solar panel produced a relatively stable voltage (18.39 V–19.71 V). The integrated hybrid system was able to stabilize the output voltage in the 12-13 Volt range and generate up to 15.37 Watts of power. Further analysis shows that with a 12 Ah capacity battery, the system can supply a 50-Watt DC lamp for approximately 2.88 hours, with a battery charging time of 3 to 3.17 hours. This study successfully demonstrates the feasibility of implementing hybrid wind-solar technology as an alternative energy source on toll roads, although further optimization is required for long-term applications.
