Utilization of Hybrid Technology of Solar Energy and Ocean Waves for Irrigation Systems in the Coastal Area of Ujong Batee, Aceh Besar

Abstract

Irrigation inefficiency is a major challenge in the shrimp farming agricultural area of Ujong Batee, Aceh Besar, where most residents depend on the shrimp farming sector. Farmers often face additional costs due to the use of electric pumps to draw water from wells, which require electrical installations and long cables. This study aims to assess the feasibility of implementing a hybrid energy-based irrigation system that combines solar energy and ocean wave energy as a solution to enhance energy efficiency and reduce operational costs for irrigation in the region. The research methodology involves measuring solar radiation intensity and ocean wave conditions at the study site, as well as analyzing the power requirements to operate water pumps.The measurement results indicate that the lowest solar intensity over a month is 5.33 kWh/m²/day, with a daily irradiation duration of 10 hours, generating a power output of 450 Wp from solar panels. Meanwhile, the ocean wave speed during the same period is 2.99 m/s, which, with a turbine diameter of 1.5 meters, can produce an electrical power of 186.65 watts. By combining these two energy sources, the proposed hybrid system can provide a sustainable solution for the energy needs of the irrigation system in the coastal area of Ujong Batee, Aceh Besar, reducing dependence on conventional electricity and lowering operational costs for shrimp farmers.
