Abstract

Transisi energi menuju sumber yang lebih bersih menjadi agenda strategis nasional dalam mendukung target Net Zero Emission (NZE) Indonesia pada tahun 2050. Aktivitas operasional pelabuhan masih bergantung pada bahan bakar fosil sehingga menjadi kontributor emisi lokal yang signifikan. Teknologi floating photovoltaic (FPV) dan oscillating water column (OWC) menawarkan solusi potensial melalui pemanfaatan energi surya dan gelombang laut. Penelitian ini menganalisis potensi energi, nilai Response Amplitude Operator (RAO), dan tegangan mooring pada konfigurasi sistem hibrid FPV-OWC di kawasan Pelabuhan Kalibaru. Pemodelan struktur dilakukan menggunakan AutoCAD dan Ansys Aqwa, sedangkan analisis fluida numerik dilakukan dengan Ansys Fluent berbasis metode Volume of Fluid (VoF). Dari lima variasi geometri OWC yang diuji, Model-1 menghasilkan amplitudo kecepatan udara tertinggi dengan nilai 1,3–1,4 m/s pada puncak positif, hingga −1,6 m/s pada puncak negatif. Validasi model hibrid numerik menunjukkan error sebesar 0,5% (di bawah ambang batas 2% IACS). Analisis RAO pada kondisi free floating memperlihatkan respons dominan pada frekuensi rendah (0,10–0,25 Hz) dengan nilai heave maksimum 1,07 m/m (heading 45°), roll 13,43 deg/m (heading 90°), dan pitch 6,93 deg/m (heading 90°). Hasil analisis mooring menunjukkan bahwa konfigurasi crossed-catenary mampu mereduksi ekskursi struktur hingga 36,3-37,1% dibandingkan konfigurasi catenary serta mempertahankan kondisi mooring tetap aman dengan nilai SF minimum sebesar 3,87. Berdasarkan analisis potensi energi, sistem (FPV) menghasilkan energi listrik sebesar 4.914,87 kWh/hari, sedangkan sistem OWC menghasilkan daya sesaat sebesar 81,213 kW.

The energy transition toward cleaner energy sources is a national strategic priority in support of Indonesia’s Net Zero Emissions (NZE) target for 2050. Port operations still rely on fossil fuels, making them a significant contributor to local emissions. Floating photovoltaic (FPV) and oscillating water column (OWC) technologies offer potential solutions through the use of solar and wave energy. This study analyzes the energy potential, Response Amplitude Operator (RAO) values, and mooring forces for a hybrid FPV-OWC system configuration in the Kalibaru Port area. Structural modeling was performed using AutoCAD and Ansys Aqwa, while numerical fluid analysis was conducted using Ansys Fluent based on the Volume of Fluid (VoF) method. Of the five OWC geometric variations tested, Model-1 produced the highest air velocity amplitude, ranging from 1.3–1.4 m/s at the positive peak to −1.6 m/s at the negative peak. Validation of the hybrid numerical model showed an error of 0.5% (below the 2% IACS threshold). RAO analysis under free-floating conditions shows a dominant response at low frequencies (0.10–0.25 Hz) with a maximum heave of 1.07 m/m (heading 45°), roll of 13.43 deg/m (heading 90°), and pitch of 6.93 deg/m (heading 90°). The results of the mooring analysis show that the crossed-catenary configuration is capable of reducing structural excursion by 36.3–37.1% compared to the catenary configuration, while maintaining safe mooring conditions with a minimum safety factor (SF) of 3.87. Based on the energy potential analysis, the FPV system generates 4,914.87 kWh of electricity per day, while the OWC system produces a peak power of 81.213 kW.
