Abstract

Kapal ikan skala kecil hingga menengah bergantung pada bahan bakar fosil untuk memenuhi kebutuhan listrik operasionalnya, sementara beban listriknya tinggi pada malam hari. Pemanfaatan photovoltaic di kapal membantu menekan konsumsi bbm, namun bersifat intermittent sehingga diperlukan sumber komplementer seperti Permanent Magnet Generator yang menggunakan turbin arus laut, serta sistem yang mampu mengintegrasikan keduanya. Penelitian ini mengimplementasikan MPPT Hybrid sebagai energy distribution controller untuk mengatur prioritas sumber, aliran daya, safety system pada pengisian baterai. Metode yang digunakan meliputi perancangan dan perakitan sistem, analisis alur kelistrikan, serta pengujian skala laboratorium pada tiga mode operasi, yaitu PV only, PMG only, dan Hybrid, menggunakan Baterai Lifepo4 48V dengan konfigurasi 16S1P, yang dilengkapi BMS DL-32A serta dummy load sebagai pengaman daya berlebih. Hasil pengujian menunjukkan bahwa MPPT Hybrid berhasil mengatur proses charging dalam tiga tahapan berurutan, yaitu boost charging hingga 54,7 V (80%), floating hingga 57,4 V (95%), dan balancing hingga 58,4 V (100%), yang berlaku konsisten pada seluruh mode pengujian. Mode Hybrid terbukti paling unggul, mampu mengisi baterai hingga penuh dalam waktu 720 menit, lebih cepat dibandingkan mode PV only (770 menit) dan jauh lebih cepat dibandingkan mode PMG only (1.580 menit). Pada mode hybrid, kontribusi PV mendominasi sebesar 92% sementara PMG menyumbang 8% sebagai sumber pendukung. Sistem proteksi bekerja dengan baik, ditandai dengan aktivasi dummy load secara otomatis saat kapasitas baterai terisi mendekati penuh (94%) untuk mencegah overcharge, serta MCB yang mampu memutus rangkaian secara otomatis pada kondisi beban arus lebih di atas 40 A. Hasil ini menunjukkan bahwa integrasi PV dan PMG melalui MPPT Hybrid dapat meningkatkan efektivitas pengisian baterai pada kapal ikan berbasis energi terbarukan dibandingkan penggunaan sumber tunggal.

Small to medium scale fishing vessels still depends on fossil fuels to meet their operational electricity needs, while their electrical load tends to be high at night. The use of photovoltaic systems on board helps reduce diesel consumption. However, PV output is intermittent, necessitating a complementary source such as a Permanent Magnet Generator driven by a marine current turbine, along with a system capable of integrating both sources. This research implements a Hybrid MPPT as an energy distribution controller to manage source priority, power flow, and charging safety for the battery. The methods employed include system design and assembly, electrical flow analysis, and laboratory-scale testing across three operating modes PV only, PMG only, and Hybrid using a 48V Lifepo4 battery in a 16S1P configuration, equipped with a DL-32A BMS and a dummy load as protection against excess power. Test results show that the Hybrid MPPT successfully manages the charging process through three sequential stages: boost charging up to 54.7 V (80%), floating up to 57.4 V (95%), and balancing up to 58.4 V (100%), consistently applied across all test modes. The Hybrid mode proved to be the most effective, fully charging the battery in 720 minutes, faster than the PV only mode (770 minutes) and considerably faster than the PMG-only mode (1,580 minutes). In Hybrid mode, PV contributed the dominant share of power at 92%, while PMG supplied the remaining 8% as a supporting source. The protection system functioned properly, as indicated by the automatic activation of the dummy load once the battery capacity approached full charge (94%) to prevent overcharging, as well as the MCB's ability to automatically interrupt the circuit under overcurrent conditions exceeding 40 A. These findings demonstrate that integrating PV and PMG through a Hybrid MPPT can improve battery charging effectiveness in renewable energy based fishing vessels compared to the use of a single power source.
