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.
