N2 - Indonesia has abundant potential for ocean wave energy that can be utilized. One of which is in the Mentawai area. The Mentawai Waters exhibit an average potential sea wave height ranging from 0.5 m to 2.3 m, with wave periods approximately between 7.8 s and 8.3 s. This study aimed to assess various Wave Energy Converter (WEC) technologies for potential implementation in this region. Based on the water depth and wave characteristics of Mentawai Waters, heaving devices with point absorber devices are suitable technology, and then this study continued to evaluate their performance. The experimental method was used using a Towing Tank at Institut Teknologi Sepuluh Nopember, Surabaya. There are two variations of floater height considered: Floater Type 1 (0.08 m) and Floater Type 2 (0.1 m). The design model was tested under wave heights of 0.04 m, 0.06 m, and 0.08 m, with wave periods ranging from 0.6 to 2.6 s. While Floater Type 2 showed an average performance improvement of approximately 1.1%, the peak performance was achieved by Floater Type 1 under the specific conditions of Hs 0.06 m and T 1.8 s. In calculating the Annual Energy Production (AEP) at a 1:1 scale in the Mentawai Waters, the highest value achievable was 21,958 kWh using 10 devices in an array configuration. This indicates that the point absorber device is the suitable WEC type, with the best average performance observed in Floater Type 2 but highest performance in Floater Type 1.
