Abstract:
Trengganis, Regina.2025. “The Effect of Implementing the Tanker Management and Self
Assessment Audit Program on Improving the Company's Operational Performance at PT.
Gemilang Bina Lintas Tirta”
This research was conducted to determine the influence of the implementation of the
Tanker Management and Self Assessment (TMSA) audit program on the operational
performance of PT Gemilang Bina Lintas Tirta. TMSA is a self-assessment program
developed by the OCIMF to improve the safety management system of oil tankers
through continuous improvement. The suboptimal implementation of TMSA in the
company, such as a manual documentation system and low audit scores, became the basis
for this study. This research employed a quantitative associative approach. Data were
collected through questionnaires distributed to 30 respondents involved in audit
implementation and operational activities. Data analysis techniques included validity and
reliability tests, Pearson correlation, and coefficient of determination (R Square),
processed using SPSS version 26. The results show that the implementation of the TMSA
audit has a very strong and significant relationship with the company's operational
performance, with a Pearson correlation value of 0.840. Furthermore, the R Square value
of 0.705 indicates that 70.5% of the variation in operational performance is explained by
the implementation of the TMSA audit program, while the remaining 29.5% is influenced
by other factors. Therefore, it can be concluded that the better the implementation of the
TMSA audit, the higher the operational performance achieved by the company in terms
of safety, efficiency, and compliance with safety management standards
