Abstract

High operational costs and significant carbon emissions associated with fossil fuel engines, which adversely affect both fishermen’s livelihoods and the environment.. The study addresses the escalating global energy consumption and the maritime sector's significant contribution to greenhouse gas emissions, aligning with Indonesia's energy transition goals and the "Blue Economy" vision. The technical analysis determined that for 15 HP equivalent vessels, a power requirement of 4.6256 kW necessitates the selection of a 10 kW Haswing Armada 10.0 electric propulsion system, with energy consumption ranging from 22.6943 kWh to 25.5936 kWh. For 5 HP equivalent vessels, the highest power requirement of 0.5781 kW leads to the selection of a 1 kW Spirit 1.0 Plus system, with energy consumption between 3.3044 kWh and 3.4689 kWh.The economic analysis, conducted over a 20-year period, reveals that while the initial investment for electric propulsion systems is higher with Rp224,355,000 for 15 HP and Rp70,620,000 for 5 HP compared to conventional engines, the operational costs are significantly lower. The Net Present Value (NPV) is positive for both Rp449,534,048.36 for 15 HP and Rp160,729,039 for 5 HP at a 5.78% discount rate. The Internal Rate of Return (IRR) is 24.84% for 15 HP and 28.77% for 5 HP, both exceeding the discount rate. The Payback Period is 6.6 years for 15 HP and 6.11 years for 5 HP, which is shorter than the 15-year loan repayment period. The Break-Even Point (BEP) is 11.3776 years for 15 HP and 10.04 years for 5 HP. The Benefit-Cost Ratio (BCR) is 2.003 for 15 HP and 2.276 for 5 HP, indicating high profitability.

Tingginya biaya operasional dan emisi karbon yang dihasilkan oleh mesin berbahan bakar fosil memberikan dampak negatif terhadap kelangsungan hidup nelayan serta lingkungan sekitar. Penelitian ini menanggapi meningkatnya konsumsi energi global dan kontribusi signifikan sektor maritim terhadap emisi gas rumah kaca, sejalan dengan arah transisi energi nasional dan visi “Blue Economy” Indonesia. Analisis teknis menunjukkan bahwa untuk kapal setara 15 HP, kebutuhan daya sebesar 4,6256 kW mengarah pada pemilihan sistem propulsi listrik Haswing Armada 10.0 berkapasitas 10 kW, dengan konsumsi energi berkisar antara 22,6943 kWh hingga 25,5936 kWh. Sementara itu, untuk kapal setara 5 HP, kebutuhan daya tertinggi sebesar 0,5781 kW menunjuk pada penggunaan sistem Spirit 1.0 Plus 1 kW, dengan konsumsi energi antara 3,3044 kWh hingga 3,4689 kWh. Analisis ekonomi yang dilakukan selama periode 20 tahun menunjukkan bahwa meskipun investasi awal sistem propulsi listrik lebih tinggi, yaitu Rp224.355.000 untuk kapal 15 HP dan Rp70.620.000 untuk kapal 5 HP, biaya operasional yang dihasilkan jauh lebih rendah dibandingkan mesin konvensional. Nilai Net Present Value (NPV) menunjukkan hasil positif sebesar Rp449.534.048,36 untuk kapal 15 HP dan Rp160.729.039 untuk kapal 5 HP pada tingkat diskonto 5,78%. Internal Rate of Return (IRR) sebesar 24,84% untuk kapal 15 HP dan 28,77% untuk kapal 5 HP, keduanya melebihi tingkat diskonto yang digunakan. Payback Period tercatat selama 6,6 tahun untuk kapal 15 HP dan 6,11 tahun untuk kapal 5 HP, lebih singkat dibandingkan periode pengembalian pinjaman selama 15 tahun. Break-Even Point (BEP) terjadi pada tahun ke-11,3776 untuk kapal 15 HP dan tahun ke-10,04 untuk kapal 5 HP. Nilai Benefit-Cost Ratio (BCR) masing-masing sebesar 2,003 dan 2,276 menunjukkan bahwa proyek ini memiliki kelayakan finansial yang tinggi.
