Abstract

Urgensi keperluan bahan bakar alternatif rendah emisi semakin meningkat seiring mengetatnya peraturan dan standard dalam upaya menekan dampak buruk emisi gas buang. Dalam hal ini, dilakukan percobaan untuk membandingkan apakah biodiesel B35 – selaku bahan bakar ramah lingkungan standard Indonesia – dan campuran antara biodiesel B35 dengan metanol sebanyak 20% lebih baik untuk penggunaan dalam mesin laut. Percobaan ini akan dilakukan menggunakan Diesel-RK, dimana biodiesel B35 bersifat sebagai kaidah pembuatan model. Model pertama didasarkan atas mesin Yanmar satu silinder berbahan bakar B35; dimana hasil pemodelan akan divalidasi menggunakan data praktis. Apabila data yang diperoleh memenuhi syarat, maka akan dilakukan pemodelan emisi yang nantinya akan diskalakan untuk penggunaan dalam mesin marine use enam silinder. Adapun dasar pemodelan mesin tersebut adalah Caterpillar 3156E. Berdasarkan hasil simulasi, ditemukan bahwa penggunaan bahan bakar campuran B35 dengan metanol 20% dapat menekan pengeluaran particulate matters sebesar 5-25 kali B35 biasa (0.0019 – 0.0125 g/kWh). Namun, hasil simulasi menunjukkan bahwa bahan bakar campuran tersebut menghasilkan NOx sebanyak 29.68 – 45.6 g/kWh; jauh diatas standard minimum IMO tier III.

The urgency of the need for low-emission alternative fuels is increasing as regulations and standards tighten to reduce the negative impact of exhaust emissions. In this regard, an experiment was conducted to compare whether B35 biodiesel—as Indonesia's standard environmentally friendly fuel—and a blend of B35 biodiesel with 20% methanol are superior for use in marine engines. This experiment will be conducted using Diesel-RK, where B35 biodiesel serves as a modeling principle. The first model is based on a single-cylinder Yanmar engine fueled by B35; where the modeling results will be validated using practical data. If the data obtained meets the requirements, emission modeling will be conducted and then scaled for use in a six-cylinder marine engine. The engine model is based on the Caterpillar 3156E. Based on the simulation results, it was found that the use of a blend of B35 fuel with 20% methanol can reduce particulate matter emissions by 5-25 times compared to regular B35 (0.0019-0.0125 g/kWh). However, simulation results show that the blended fuel produces NOx of 29.68 – 45.6 g/kWh, far above the minimum IMO Tier III standard.
