<![CDATA[Indonesia is the largest archipelagic state in the world, consisting of approximately 17,508 islands and possessing the second-longest coastline globally after Canada. The intensity of maritime traffic in Indonesian waters, particularly along the Indonesian Archipelagic Sea Lanes (ALKI), has given rise to various issues, one of which is marine pollution. Article 192 of the 1982 United Nations Convention on the Law of the Sea (UNCLOS) stipulates that every state has the obligation to protect and preserve the marine environment, emphasizing that marine ecosystems must be safeguarded and sustained by all nations. This study aims to analyze the applicability of international maritime law instruments in addressing marine pollution and to examine the accountability of foreign states for marine pollution occurring within the Indonesian Archipelagic Sea Lanes (ALKI), particularly in the Riau Islands and the Java Sea, which form part of ALKI I. The research employs a normative juridical method. The data sources are supported by both primary and secondary materials, referring to statutory regulations and relevant literature concerning the control of marine pollution in the Indonesian Archipelagic Sea Lane I (ALKI I). Foreign vessels navigating through ALKI I are required to comply with Indonesian laws and regulations. The measures undertaken by Indonesia to address violations include the application of the principle of strict liability, holding foreign vessels absolutely responsible for acts of ocean dumping in Indonesian waters to prevent the spread of adverse environmental impacts.]]>
