The sea connects thousands of islands, serving as a conduit for the movement of people, goods, and products between regions. Passenger ships, cargo vessels, ferries, and traditional boats facilitate inter-island travel, including to areas that are difficult to reach by land. Beyond supporting mobility, maritime transport underpins economic activity, as ships are used to transport large volumes of passengers and cargo. However, maritime transport carries inherent risks of accidents, which can lead to material losses, environmental damage, and even loss of life. Such accidents may arise from various factors, including natural conditions, human error, technical issues, or operational management failures. Natural factors include high waves, strong winds, powerful ocean currents, and sudden weather changes. Port oversight plays a crucial role in ensuring the safety of vessels before, during, and after their voyages; officials inspect ship documentation, technical condition, cargo, and the presence of essential safety equipment, such as fire extinguishers and life jackets. The Harbor Master and Port Authority (KSOP) of Tanjung Perak is tasked with overseeing maritime safety, including the verification of a vessel's seaworthiness. To minimize accidents and untoward incidents, the KSOP of Tanjung Perak implements several mitigation measures, such as the use of online applications for purchasing ferry tickets and verifying the identities of passengers and vehicles against the digital manifest. Accident prevention also relies heavily on the preparedness of human resources; crew members and port personnel must undergo regular training. Mitigating maritime accidents at the Port of Tanjung Perak requires collaboration among ship crews, harbor pilots, port officials, tugboat operators, terminal managers, and other relevant agencies. Before setting sail, the captain and crew must ensure that the vessel is seaworthy.
