Abstract

Meningkatnya kebutuhan teknologi ramah lingkungan dalam industri maritim mendorong pengembangan bahan bakar alternatif untuk mengurangi emisi gas rumah kaca. Penelitian ini menganalisis unjuk kerja mesin dual fuel diesel-hidrogen menggunakan simulasi MATLAB pada mesin Yanmar TF 85 MH dengan campuran 50% hidrogen dan 50% bahan bakar B35 pada berbagai kondisi beban (1000-5000W) dan putaran mesin (1200-2200 RPM). Model simulasi menunjukkan akurasi tinggi dengan kesalahan kurang dari 5% untuk semua parameter utama. Sistem dual fuel menghasilkan peningkatan daya sebesar 2,1% dari 7,5 kW menjadi 7,7 kW, peningkatan torsi sebesar 1,8% dari 33,3 Nm menjadi 33,9 Nm pada 1600 RPM, dan perbaikan efisiensi bahan bakar (SFOC) sebesar 3,5% dari 171 g/kWh menjadi 165 g/kWh pada 2000 RPM. Penggunaan hidrogen berhasil mengurangi emisi CO₂ sebesar 20-30%, dengan contoh reduksi dari 1,42 kg/kWh menjadi 0,83 kg/kWh (42%) pada beban 1000W, dan dari 3,98 kg/kWh menjadi 2,81 kg/kWh (29%) pada beban penuh. Sistem dual fuel juga mengurangi smoke value sebesar 11-12%, dari 4,68% menjadi 4,14% pada beban 1kW, namun mengalami peningkatan emisi NOx sebesar 8-15%, dari 393,1 ppm menjadi 462,4 ppm pada beban 4000W akibat peningkatan temperatur pembakaran. Teknologi dual fuel diesel-hidrogen terbukti layak diterapkan untuk meningkatkan efisiensi energi dan mengurangi emisi dalam industri maritim, meskipun masih memerlukan pengembangan sistem kontrol emisi Nox.

The increasing demand for environmentally friendly technology in the maritime industry drives the development of alternative fuels to reduce greenhouse gas emissions. This study analyzes the performance of a dual-fuel diesel-hydrogen engine using MATLAB simulation on a Yanmar TF 85 MH engine with a mixture of 50% hydrogen and 50% B35 fuel under various load conditions (1000-5000W) and engine speeds (1200-2200 RPM). The simulation model shows high accuracy with error rates less than 5% for all main parameters. The dual-fuel system produces a power increase of 2.1% from 7.5 kW to 7.7 kW, torque increase of 1.8% from 33.3 Nm to 33.9 Nm at 1600 RPM, and fuel efficiency improvement (SFOC) of 3.5% from 171 g/kWh to 165 g/kWh at 2000 RPM. Hydrogen usage successfully reduces CO₂ emissions by 20-30%, with examples showing reduction from 1.42 kg/kWh to 0.83 kg/kWh (42%) at 1000W load, and from 3.98 kg/kWh to 2.81 kg/kWh (29%) at full load. The dual-fuel system also reduces smoke value by 11-12%, from 4.68% to 4.14% at 1kW load, but experiences NOx emissions increase of 8-15%, from 393.1 ppm to 462.4 ppm at 4000W load due to increased combustion temperature. Dual-fuel diesel-hydrogen technology proves feasible for improving energy efficiency and reducing emissions in the maritime industry, although NOx emission control system development is still required.
