Modification of Ballast Filtering Device on John Lie Training Ship to Prevent Marine Pollution

This study aims to present appropriate selection methods for evaluation, analysis, and comparison between different ballast water treatment technology systems in order make good decisions selecting the most optimal system. research designed a filter device on John Lie training ship prevent marine pollution due species movement through transfer process by referring D2 standard of IMO Ballast Water Management Convention. During ballasting process, contains thousands animals plants that are carried tanks, causing problems environment human health. The modification filtration tool researcher used 0,1 mm 0,01 net tied tank inlet pipe using clamp ship. can fully be during filling from port seawater enter this results shown after passing with total plate count 36 microorganisms indicate system meet BWM Convention Regulation.
