Abstract

MARPOL 73/78 annex VI regulasi 14 mengatur tentang kandungan sulfur pada bahan bakar sebesar 0.5% secara global. MARPOL 73/78 annex VI regulasi 13 mengatur tentang kandungan Nox (g/KWH) berdasarkan RPM dan tahun pembuatan kapal. MARPOL 73/78 annex VI chapter 4 mengatur tentang kandungan CO2 berlaku untuk kapal baru yang dibangun setelah 1 Januari 2013 berisi penurunan prosentase emisi setiap 5 tahun. Guna memenuhi standar tersebut, perusahaan pelayaran perlu memikirkan lebih lanjut dampak dari aktivitas operasional armada kapalnya, namun masih memenuhi batasan dari kondisi green. Tentunya akan ada biaya yang harus dikorbankan untuk dapat tercipta Green Shipping. Voyage calculation diperlukan dalam perhitungan studi kasus. Opsi Green yang dipilih adalah dengan mengurangi kecepatan atau mengkobinasikannya dengan mengganti bahan bakar menjadi low sulfur fuel, serta menambahkan alat seperti scrubber, direct water injection, exhaust gas recirculation, humid air motor, selective catalityc reduction, dan merubah kapal menjadi berbahan bakar LNG. Dari opsi green yang diberikan dicari strategi green yang menghasilkan cost dan nilai emisi yang paling minimum setelah x tahun. Pada tugas akhir ini digunakan 5 jenis kapal yang berbeda untuk merepresentasikan kondisi pelayaran peti kemas Indonesia saat ini berdasarkan pada kapasitas angkut dan tahun pembuatannya. Setelah dilakukan perhitungan diperoleh bahwa opsi green yang paling sesuai adalah dengan menambahkan alat exhaust gas recirculation, direct water injection dan mengganti bahan bakar ke low sulfur fuel, yang menghasilkan profit paling maksimum sesuai batas kondisi green. ================================================================================================================== MARPOL 73/78 annex VI 14th regulates sulfur content 0.5% for globally. MARPOL 73/78 annex VI 13th regulates Nox (g/KWH) content based on RPM and the year when the ship built. MARPOL 73/78 annex VI chapter 4 regulates CO2 content for new ships built after January 1st 2013; it has an emission percentage reduction target updated every 5 years. In order to meet this standard, shipping companies need to consider the effects of their operational activities to remain within the limit of their green condition. Shipping companies need to maintain a balance between environmental issues and profit that needs to be made. A Voyage Calculation is required on these case studies. The various possible green options include reducing the speed of the ship, combining the fuel with low sulfur based fuel, adding more equipment such as scrubber, direct water injection, exhaust gas recirculation, humid air motor, selective catalityc reduction, and even changing the ship to use LNG based fuel. Based on the green options given before, the green strategy which minimizes cost and emissions after x period of time was calculated. This research used 5 different ships to represent current Indonesian domestic shipping condition based upon the ships' payload and the year built. The calculation results show that adding exhaust gas recirculation, direct water injection and changing the fuel into low sulfur fuel maximize profit and are compatible with green standards.
