Optimalisasi sistem ballast water treatment system pada kapal mt.capbara guna meningkatkan efektivitas pengolahan air ballast serta mendukung efisiensi operasional kapal

Abstract

The Ballast Water Treatment System (BWTS) is a System used to treat ballast water in order to comply with the requirements of the Ballast Water Management Convention, (BWMC) Regulation D-2 and to prevent the transfer of aquatic organisms that may disrupt Marine ecoSystems. MT. Capibara is equipped with the BalClor® Ballast Water Management System (BWMS), which utilizes the electrochlorination method in the ballast water treatment process. Based on the observations, the TRO Analyzer displayed a reading of 6.27 mg/L during the verification process prior to de-ballasting at Tuapse Port, Black Sea. This study aims to identify the factors affecting BWTS operation and the efforts that can be undertaken to support the effectiveness of System operation. The research employed a qualitative descriptive method. Data were collected through observation, interviews, documentation, and literature review during the sea practice period on board MT. Capibara. Data analysis was conducted using the Fishbone Analysis method to identify factors influencing BWTS operation based on the aspects of Machine, man, method, and Environment. The results indicate that BWTS operation is influenced by several factors, including the performance of the TRO Analyzer, the condition of the chlorine buffer solution, the performance of the Oxidant Dosing Unit (ODU), monitoring of BWTS equipment conditions, crew familiarization, monitoring by the Duty Officer, maintenance implementation, monitoring of ballast operations, seawater salinity, and water characteristics. The analysis shows that increasing crew familiarization with the BWTS and coordinating with the maker to conduct comprehensive System inspections and troubleshooting are efforts that can support BWTS operation. In addition, the replacement of Consumable parts in accordance with the maker’s recommendations and the implementation of periodic maintenance are necessary to maintain System reliability. By implementing these measures, BWTS operation is expected to become more effective, thereby ensuring that the ballast water treatment process continuously supports compliance with the requirements of BWMC Regulation D-2.
