Abstract:
Sulthon, Aldi. 2025. "The Effect of ISO 45001:2018 Implementation on the Level of
Occupational Health and Safety on the Triputra LNG/C Vessel”
This study examines the influence of the implementation of ISO 45001:2018 on the level
of Occupational Health and Safety (K3) aboard the LNG/C Triputra vessel managed by
PT Humolco LNG Indonesia. Using a quantitative approach, data were collected through
questionnaires distributed to 35 crew members and employees of the QSSHe department.
The results of correlation analysis showed a strong positive relationship (r = 0.807)
between ISO 45001:2018 implementation and K3 performance. The coefficient of
determination (R²) indicated that 65.2% of the variation in K3 levels could be explained
by ISO 45001:2018 implementation, with the remaining 34.8% attributed to other factors.
Regression analysis further confirmed a significant positive impact (t-value = 7.856 > ttable = 2.034), supporting the hypothesis that ISO 45001:2018 effectively enhances K3
aboard the vessel. The findings suggest that PT Humolco LNG Indonesia should maintain
and innovate its K3 management practices, such as investing in automation and
monitoring technologies, to further reduce workplace accidents and injuries.
