Abstract
Penelitian ini bertujuan untuk menganalisis potensi energi gelombang laut serta menentukan lokasi paling prospektif untuk penerapan Wave Energy Converter (WEC) yang dapat diintegrasikan dengan breakwater pada enam titik lokasi di perairan selatan Pulau Jawa, yaitu Pelabuhan Jayanti, Pelabuhan Pamayang, PLTU Karangkandri, PLTU Adipala, PLTU Sudimoro, dan Pelabuhan Tambakrejo. Data gelombang diperoleh melalui pemodelan numerik berbasis Simulating WAves Nearshore (SWAN) untuk memperoleh tinggi gelombang signifikan (Hs) dan periode gelombang puncak (Tp) yang kemudian diolah untuk mendapatkan wave scatter diagram dan power matrix. Selanjutnya, potensi lokasi dievaluasi menggunakan lima indeks, yaitu Coefficient of Variance (CoV), Monthly Variability Index (MVI), Seasonal Variability Index (SVI), Wave Energy Development Index (WEDI), dan Optimum Hotspot Identifier (OHI). Hasil penelitian menunjukkan bahwa potensi energi gelombang tertinggi berada pada wilayah PLTU Sudimoro (49.87 kW/m), Karangkandri (42.67 kW/m), dan Adipala (41.67 kW/m), sedangkan Jayanti, Pamayang, dan Tambakrejo memiliki energi relatif rendah (< 10 kW/m). Berdasarkan indeks evaluasi, PLTU Sudimoro merupakan lokasi paling prospektif dengan CoV terendah (0.38), MVI dan SVI terendah (0.67 dan 0.40), serta nilai OHI tertinggi (74.81). Analisis produktivitas energi empat tipe teknologi WEC di lokasi terbaik (Sudimoro) menunjukkan bahwa tipe Floating Point Absorber menghasilkan capacity factor tertinggi sebesar 7.29%, diikuti Overtopping Device (7.20), Hinged Point Absorber (3.53), dan Oscillating Water Column (3.24). Secara keseluruhan, penelitian ini menyimpulkan bahwa perairan selatan Jawa memiliki potensi energi gelombang yang signifikan, dengan area PLTU Sudimoro sebagai lokasi yang paling berpotensi untuk implementasi integrasi breakwater dan WEC. Teknologi yang paling produktif untuk kondisi gelombang setempat adalah WEC tipe Floating Point Absorber, yang memiliki nilai capacity factor paling tinggi di antara teknologi yang dianalisis.

This study aims to analyze the potential of ocean wave energy and determine the most prospective locations for the application of Wave Energy Converters (WECs) that can be integrated with breakwaters at six locations in the southern waters of Java Island, namely Jayanti Port, Pamayang Port, Karangkandri Power Plant, Adipala Power Plant, Sudimoro Power Plant, and Tambakrejo Port. Wave data were obtained through numerical modeling based on Simulating Waves Nearshore (SWAN) to obtain significant wave height (Hs) and peak wave period (Tp), which were then processed to obtain wave scatter diagrams and power matrices. Furthermore, the potential of the locations was evaluated using five indices, namely the Coefficient of Variance (CoV), Monthly Variability Index (MVI), Seasonal Variability Index (SVI), Wave Energy Development Index (WEDI), and Optimum Hotspot Identifier (OHI). The results of the study show that the highest wave energy potential is in the Sudimoro (49.87 kW/m), Karangkandri (42.67 kW/m), and Adipala (41.67 kW/m) areas, while Jayanti, Pamayang, and Tambakrejo have relatively low energy (< 10 kW/m). Based on the evaluation index, the Sudimoro power plant is the most prospective location with the lowest CoV (0.38), lowest MVI and SVI (0.67 and 0.40), and highest OHI value (74.81). An analysis of the energy productivity of four types of WEC technology at the best location (Sudimoro) shows that the Floating Point Absorber type produces the highest capacity factor of 7.29%, followed by the Overtopping Device (7.20), Hinged Point Absorber (3.53), and Oscillating Water Column (3.24). Overall, this study concludes that the southern waters of Java have significant wave energy potential, with the Sudimoro power plant area being the most promising location for the implementation of breakwater and WEC integration. The most productive technology for local wave conditions is the Floating Point Absorber type WEC, which has the highest capacity factor among the technologies analyzed.
