ANALISIS PENGARUH PERUBAHAN SUHU TERHADAP TEKANAN MUATAN PADA CARGO TANK DI LPG/C GAS NURI ARIZONA

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.
