DESAIN KONFIGURASI SISTEM PROPULSI HYBRID TERHADAP PENGURANGAN KONSUMSI BBM KAPAL PENANGKAP IKAN 30 GT (Configuration Design of a Hybrid Propulsion System to Reduce Fuel Oil Consumption of a 30 GT Fishing Vessel)

This study aims to reduce fuel oil consumption of a 30 GT fishing vessel through configuration design of diesel and electric motor hybrids propulsion system. The configuration design of hybrids propulsion system systematically include; i) loading assumption; ii) prediction of speed-thrust; iii) prediction of fuel oil consumption. Design of hybrids propulsion system was analyzed by using the concept of time domain simulation of vessel movement. The result indicated that the hybrids propulsion system implemented to fishing vessel was very effective to reduce fuel consumption compared with conventional propulsion system, especially in variation of loading and speed condition.Keywords: fishing vessel, hybrids propulsion system and fuel oilPenelitian ini bertujuan untuk mengurangi konsumsi bahan bakar minyak kapal penangkap ikan 30 GT melalui desain konfigurasi sistem propulsi hybrid diesel-listrik. Secara sistematis perancangan sistem propulsi hybrid meliputi; i) asumsi pembebanan operasi; ii) prediksi speed-thrust; iii) prediksi konsumsi bahan bakar. Desain sistem propulsi hybrid dianalisis dengan menggunakan konsep time domain simulation pergerakan kapal. Hasil penelitian menunjukkan bahwa penggunaan sistem propulsi hybrid pada kapal penangkap ikan sangat efektif dalam mengurangi konsumsi bahan bakar dibandingkan dengan sistem propulsi konvensional, terkhusus pada kondisi pemuatan dan kecepatan yang bervariasi.Kata kunci: Bahan bakar, kapal penangkap ikan, sistem propulsi hybrid
