Abstract:
This study aims to determine the effect of tank pressure alarm response speed on the
safety of LNG cargo operations. The problem examined is the variation in response level,
coordination, and crew readiness in following up on tank pressure alarms, which
potentially affects the safety of LNG cargo operations on the moss-type vessel SS. Energy
Frontier, operated by Mitsui O.S.K Lines. The population of this study consisted of all
crew members, with a sample of 47 respondents selected using the census technique. A
quantitative research approach was applied, with data collected through observation,
questionnaires, and documentation. Data were analyzed using descriptive statistics,
validity testing, reliability testing, correlation coefficient analysis, coefficient of
determination analysis, simple linear regression, and hypothesis testing (partial t-test) to
determine the relationship between tank pressure alarm response speed as the independent
variable (X) and LNG cargo operation safety as the dependent variable (Y). The results
indicate that tank pressure alarm response speed has a positive and significant effect on
the safety of LNG cargo operations. This is evidenced by the t-count value being greater
than the t-table value, so H0 is rejected and H1 is accepted. The coefficient of
determination shows that the tank pressure alarm response speed variable contributes
74.1% to LNG cargo operation safety, while the remaining percentage is influenced by
other factors outside the scope of this study.
