【 摘 要 】

Commercial vessels that do not conduct ballast water exchange, in accordance with International Convention Ballast Water Management, will endager the environment of ports. This research is aimed to know the metal content in ballast water tank of commercial vessels that have not performed ballast water exchange, in accordance with regulations of International Maritime Organization (IMO). The present research is focused on the heavy metal content of ballast water of commercial vessels, both passenger or cargo vessells, berthing in Port of Tanjung Emas Semarang (PTES). Water sample in ballast tank is collected by method of AAS (Atomic Absorption Spectrophotometer). Results of the research show that the content of Cd is about 0.001-0.46 mg l-1, and Zn is about 0.001-2.464 mg l-1. Based on the Decree of Minister of Environment Number 51/2004, the heavy metal content of Cd and Zn has exceeded quality standards of sea water for port water, which is 0.1 mg l-1both.
