Abstract

Sea water often used onboard to increase the stability of ship during loading and unloading process which cause a movement of gravity point. This sea water also used to keep the propeller stay below the water and also to increase manouvering ability while sailing. This water is what we called ballast water. While ballast water is very essential for safety and efficient operation, it also brings a disadvantages to the environment because sea water contains variety of microorganisms, like viruses, bacteria, small and adult larval stage and many other plants. The displacement of sea water during loading and unloading process will automatically move the contaminants of sea water to another places which have different characteristics. On 2004, IMO set ballast water management convention which stated that ballast water must be treated first before dicharged. UV treatment is one of methods to treat microorganisms in ballast water which mostly used globally. This bachelor thesis aim to give a correct technical and economical recommendation on the installation of Ballast water treatment equipment on MT. Senipah Data obained from the analysis the power consumption of equipment is 75 kW, meanwhile the power consumption still can be covered by generator with 87,7 % load factor. The decreasing flowrate is about 80 m3/h, so that the ballasting time will be 16 hours. This equipment could be placed on floor deck in frame 39 – 43. The economical analysis obtained that the installation cost of this equipment is around Rp 3.222.503.000 ============================================================================================= Air laut digunakan untuk menjaga keseimbangan kapal selama aktifitas yang mengakibatkan perubahan titik gravitasi kapal seperti proses bongkar dan muat kapal, dan untuk menjaga propeller agar tetap berada dibawah permukaan air laut dan juga menambah kemampuan manouver kapal selama perjalanan. Air laut tersebut sering dinamakan air ballast. Sementara air ballast esensial untuk keselamatan dan efisien untuk operasi, air ballast juga memiliki kerugian karena mengandung bermacam mikroorganisme, seperti virus dan bakteri, larva kecil dan dewasa dan banyak tumbuhan dan hewan laut lainnya. Perpindahan air ballast melalui proses bongkar muat akan secara otomatis memindahkan air ballast dan kontaminannya dari suatu tempat ke tempat lainnya yang memiliki karakteristik perairan yang beda. Pada tahun 2004, IMO menciptakan ballast water management convention, yang mengharuskan air ballast untuk diolah terlebih dahulu sebelum dikeluarkan. UV treatment merupakan metode pengendalian mikroorganisme air ballast yang paling banyak digunakan di kapal. Tujuan dari penelitian ini adalah unutuk memberikan rekomendasi UV treatment yang tepat secara teknis dan ekonomis pada kapal MT. Senipah milik PT. Pertamina (persero). Hasil analisa yang didapatkan adalah alat ballast treatment yang akan diinstall memiliki power consumption sebesar 75 kW, namun power consumption tersebut masih dapat dicover oleh generator dengan load factor sebesar 87,7% dengan penurunan flowrate pompa existing sebesar 80 m3/h sehingga waktu ballasting menjadi 16 jam. Alat ini dapat diletakkan diatas floor deck pada frame 39 hingga frame 43. Analisa ekonomi yang didapat bahwa biaya instalasi peralatan ini membutuhkan dana sebesar Rp 3.222.503.000
