Perawatan Oil Water Separator di Kapal KM Mutiara Berkah II

Abstract

Marine pollution caused by the disposal of oily waste from ships is an environmental problem that requires serious attention. The Oil Water Separator (OWS) is auxiliary equipment on ships used to separate oil from bilge water before it is discharged into the sea in accordance with MARPOL Annex I regulations, which limit oil content to a maximum of 15 PPM. However, several operational problems were found that caused the OWS performance on board KM Mutiara Berkah II to become less optimal. This study aims to determine the maintenance frequency of the OWS, identify the indicators and causes of OWS disturbances, and analyze maintenance efforts to maintain optimal OWS performance. This study used a qualitative research method with data collection techniques consisting of observation, interviews, documentation, and literature study during sea practice in 2025 aboard KM Mutiara Berkah II owned by PT Atosim Lampung Pelayaran. The results showed that OWS maintenance was carried out daily, weekly, and monthly. The problems found included damage to the Oil Content Monitor (OCM) motherboard, accumulation of sludge and oil in the coalescer, filters, and separator tank, causing the oil content to reach 17-18 PPM, exceeding the required standard limit. After cleaning, flushing, and component repairs were carried out, the OWS performance returned to normal and the system operated according to SOP. Therefore, periodic maintenance and routine component inspections are essential to maintain OWS performance and prevent marine environmental pollution.   ABSTRAK Pencemaran laut akibat pembuangan limbah minyak dari kapal menjadi salah satu permasalahan lingkungan yang perlu mendapat perhatian serius. Oil Water Separator (OWS) merupakan peralatan bantu di kapal yang berfungsi memisahkan minyak dari air got sebelum dibuang ke laut sesuai ketentuan MARPOL Annex I dengan batas maksimal kandungan minyak 15 PPM. Namun, dalam pengoperasiannya masih ditemukan beberapa kendala yang menyebabkan performa OWS tidak bekerja secara optimal di kapal KM Mutiara Berkah II. Penelitian ini bertujuan untuk mengetahui frekuensi perawatan OWS, mengidentifikasi indikator dan faktor penyebab gangguan pada OWS, serta mengetahui upaya perawatan untuk menjaga performa OWS agar tetap optimal. Penelitian ini menggunakan metode kualitatif dengan teknik pengumpulan data berupa observasi, wawancara, dokumentasi, dan studi literatur selama praktek laut tahun 2025 di KM Mutiara Berkah II milik PT Atosim Lampung Pelayaran. Hasil penelitian menunjukkan bahwa perawatan OWS dilakukan secara harian, mingguan, dan bulanan. Gangguan yang ditemukan meliputi kerusakan motherboard Oil Content Monitor (OCM), penumpukan lumpur dan minyak pada coalescer, filter, dan tabung pemisah yang menyebabkan kadar minyak mencapai 17-18 PPM atau melebihi batas standar. Setelah dilakukan cleaning, flushing, dan perbaikan komponen, performa OWS kembali normal dan sistem dapat bekerja sesuai SOP. Dengan demikian, perawatan berkala dan pemeriksaan komponen secara rutin sangat penting untuk menjaga kinerja OWS dan mencegah pencemaran lingkungan laut.
