Jatmiko, Ardian Reviera. 2025. “The Effect of Fairway Survey Implementation at Port
Entry Channels on Navigation Safety within the Directorate of Navigation Environment”
As an archipelagic country with thousands of islands, Indonesia faces serious challenges
in ensuring maritime safety. One of the strategic efforts to support safe navigation is the
implementation of fairway surveys at port entry channels, aimed at ensuring that shipping
lanes are free from hazards and comply with international safety standards. This study
was initiated due to the critical role of accurate hydrographic data in supporting safe
navigation, as well as the observed limitations in human resources, reliability of survey
equipment, and data accuracy in the field. The main research question is to determine the
extent to which the implementation of fairway surveys affects navigation safety. The
study employed a quantitative descriptive approach using a Likert-scale questionnaire,
distributed to 30 personnel of the Directorate of Navigation as respondents. The results
indicate that the implementation of fairway surveys—consisting of competent human
resources, reliable survey equipment, and accurate data—has a significant influence on
navigation safety. This is evidenced by the simple linear regression analysis which shows
a coefficient of determination of 71,8%, meaning that the fairway survey implementation
contributes 71,8% to the improvement of navigation safety, while the remaining
percentage is influenced by other external factors. The study concludes that improving
fairway survey quality is essential and can be achieved through enhancing the competence
of survey personnel, maintaining and procuring proper survey equipment, and ensuring
consistent and accurate data collection. The Directorate of Navigation is advised to
strengthen its planning and budgeting efforts to ensure national maritime safety.
