Abstract:
Sinurat, Sonia Amelia. 2025. “The Influence of Maritime Safety Information on
Shipping Safety in Tanjung Priok Waters at the Directorate of Navigation”
Tanjung Priok is the busiest port in Indonesia, with dense ship traffic and complex
maritime activities. The high dynamics of shipping traffic in this area pose significant
maritime risks. One of the essential tools to ensure shipping safety is Maritime Safety
Information (MSI), which provides timely updates related to navigation warnings,
meteorological conditions, and other maritime hazards. However, current observations
reveal that there are still problems such as delays in the dissemination of information and
uneven access to MSI across vessels.
Unlike previous studies that analyzed MSI implementation in general or in strait regions,
this research specifically investigates the quantitative impact of MSI on maritime safety
in Tanjung Priok waters. The focus on one of Indonesia’s busiest ports highlights the
urgency of assessing the effectiveness of MSI systems under high-density maritime
conditions.
The main research questions are to what extent does Maritime Safety Information
influence shipping safety in Tanjung Priok waters and how significant is the effect of
delayed dissemination of MSI on the level of maritime safety. This study adopts a
quantitative approach by distributing questionnaires to ship crew members, Directorate
of Navigation personnel, and other stakeholders. The data is analyzed using a simple
linear regression method to determine the statistical correlation between MSI
(independent variable) and shipping safety (dependent variable).
The findings demonstrate a strong positive correlation between the effectiveness of MSI
dissemination and increased safety at sea. The results indicate that approximately 65%
of the variations in shipping safety can be explained by the timeliness, accuracy, and
accessibility of MSI. Real-time updates through NAVTEX, radio, and VTS systems help
in decision-making processes, particularly in avoiding collisions, grounding, and
navigating during bad weather.
This study concludes that MSI plays a critical role in enhancing shipping safety in
Tanjung Priok waters. It is recommended that the Directorate of Navigation improve the
infrastructure and digital systems for MSI distribution, ensure faster data verification
processes, and enhance the awareness of VTS operators to maintain effective safety
communication with ships in their area of responsibility.
