The study population includes Revenue Time Charter, Freight Charter, Operational Cost, and Operating Profit Margin at PT. Bintang Samudera Mandiri Lines Tbk from 2020. The sample consists of monthly data from January 2020 to December 2022, with 36 samples from 5 company vessels. The path analysis method is used with the help of SPSS Ver. 26 software. The study results show a positive and significant effect between Revenue and Operational Cost on the Time Charter and Freight Charter systems. Revenue also has a positive and significant effect on Operating Profit Margin in both systems. However, Operational Cost only has a positive and significant effect on Operating Profit Margin in the Freight Charter system.
