Abstract

Pada konvensi MARPOL 73/78 Annex 1 untuk kapal tanker berukuran >150 GRT (selain dari kapal tanker berukuran > 400 GRT) dan Marpol Consolidate 2006 Annex 1 Regulation 32 “Oil/Water interface Detector” dan Regulation 34 “Control Of Dischare Of Oil” kamar mesin harus dilengkapi dengan sarana Oily water separator sebagai media pemisah antara air dan minyak. Tujuan artikel ini adalah untuk mengetahui permasalahan sehubungan dengan kendala pengoperasian Oily Water Separator. Metode pengumpulan data pada penulisan artikel ini studi literatur, wawancara, observasi, studipustaka. Hasil dari pemecahan permasalahan perawatan secara rutin perlu dilakukan untuk menjaga kuliatas dari performa mesin Oily Water Separator. Pengoperasian oleh operator kapal harus sesuai dengan standar operating procedure dengan baik dan benar . Selain itu pengecekan fungsi oil discharge monitoring pada sensor oil content meter perludilakukan agar pengaturan oil content meter  yang sesuai dengan peraturan dari MARPOL Annex 1 yaitu sebesar15 ppm.

Abstract

Shipyard industry  is one of the most  important chain  on the national shipping system. Notably to maintains the vessels condition in order to get adjustment of The Indonesia Classification Bureaustandard. Shipyard’s productivity depends on the graving dock capacity, man productivity and work method. Empirical studies show that man competiveness and productivity and effective work method are primary factors which affects choice rate from shipping companies to a shipyard. The research goal was to analyzed the effect of man productivity and work method toward graving dock performance in PT. Janata Marina Indah Semarang. Multiple linear  regression used as a method in this research. Methodology use basic is difficulty to identify relating directly from man productivity and work method toward graving dock performance. The sampling method using  purposive random sampling with 35 respondents who have long experience in the graving dock works. The result of regression analysis is:  Y= -0,357 + 0,256 X1 + 0,249 X2. The result shows that two factors both man productivity and work method, are have  significant effect toward graving dock performance.
