Abstract
Transportasi maritim turut bertanggung jawab dalam hal perlindungan lingkungan, sehingga pengukuran harus dilakukan terhadap logistik dan ruang lingkup transportasi maritim yang dikembangkan oleh IMO guna mengurangi emisi dari kapal. Penelitian ini bertujuan untuk menentukan operasional kapal terbaik guna mengurangi konsumsi bahan bakar melalui konsep Energy Efficiency Operational Indicator (EEOI). Dengan membandingkan nilai EEOI recorded dan EEOI predicted, dimana perbedaan kedua nilai ini merepresentasikan fouling lambung dan propeller serta degradasi performa engine. Diperoleh bahwa nilai error sebesar 4.219% terjadi pada kapal BNI Castor dengan rentang waktu opersional 13 bulan. Sedangkan pada BNI Capella, nilai error sebesar 5.91% dengan waktu operasional selama 14 bulan. Efek dry-docking dilakukan pada kapal Tropic Orion, dimana memberikan pengurangan nilai error sebesar 6.57%. Nilai error ini sebagai dasar penurunan kecepatan operasional kapal, dimana pada penurunan kecepatan sebesar 0.5 knot memberikan pengurangan konsumsi bahan bakar sebesar 0.58% dan penambahan waktu layar sebesar 7.31% pada BNI Castor, sedangkan sebesar 0.5% untuk pengurangan konsumsi bahan bakar dan 4.88% penambahan waktu layar untuk BNI Capella, sedangkan efek dry-docking mengurangi error sebesar 6.57% pada Tropic Orion. Dengan menurunkan kecepatan kapal, maka akan mengurangi konsumsi bahan bakar namun akan menambah waktu layar. Kondisi lingkungan berperan penting sehubungan dengan pengurangan konsumsi bahan bakar.
================================================================== The maritime transportation takes a role to responsible related to environment protection, therefore the measurement should be done for logistic and related maritime transportation scope that already developed by IMO to reduce emission from vessel. This research aim to find the optimum operational speed in accordance to reduce fuel consumption by using energy efficiency operational indicator (EEOI) concept. By comparing the recorded EEOI with predicted EEOI, the error represents hull and propeller fouling and engine degradation performance. The study shown that for AHTS BNI Castor gives 4.219% error for 13 months of operation, while AHTS BNI Capella gives 5.19% error for 14 months of operation. Dry docking effect by using AHTS Tropic Orion that gives about 6.57% of error reduction due to maintenance while dry-docking. The error as the basis to determine tho ship speed reduction, where the 0.5 knot of speed reduction gives a fuel consumption reduction about 0.58% for BNI Castor, in contrary gives about 7.31% addition sailing time. Fuel consumption reduces about 0.5% when the speed reduction applied to BNI Capella about 0.5 knot, but gives about 4.88% of additional sailing time. By applying slower speed will gives more reduction to fuel consumption, while the consequence will add the sailing time. The environment condition plays big role related to fuel consumption reduction.
