Abstract:
This study analyze the effect of temperature changes on cargo pressure inside the
cargo tanks of the LPG/C Gas Nuri Arizona during the LPG mix discharge process. Using
a correlational quantitative method, temperature and pressure data were obtained through
observation and cargo documentation, then analyzed using Pearson correlation test,
coefficient of determination, simple linear regression, and t-test with IBM SPSS 26
software. The results show a strong relationship between temperature and pressure, with
a correlation coefficient of 0.767 and a contribution of temperature changes to pressure
variation of 58.8%. The regression equation Y=0.348 X + 0.496 Y, that indicates that an increase of 1°C in temperature leads to a pressure increase of 0.348 bar. In conclusion, temperature changes have a significant influence on cargo pressure, making temperature monitoring during discharge crucial for maintaining safety and ensuring smooth ship operations.
