This research aimed to know both the direct and indirect contribution of cargo loading and discharging time to the Loss and gain of coal mediated by load quantity. The process of data collecting was done through secondary data taken from the loading port of Jetty in Samarinda Port and the discharging port of Muara Berau, East Kalimantan. During 2020, there was an average loss of coal cargo of as much as 56 percent. This was caused by the long waiting discharge time during the loading and discharging. Another problem was the long waiting discharge time, as many Mother Vessels, tugboats, and barges entered the Jetty port and made a density there. The research method used path analysis with the loading-discharging unit as the source of secondary data on the determining factors of load quantity and the Loss and gain of coal cargo. This research indicated that one of the dominant factors was waiting discharge time, as a problem frequently occurred when vessels would berth in the port for discharging activities. The key finding was the necessity for the competent party to pay special attention to the factors contributing to vessels’ waiting discharge time in the port by providing services as maximally as possible through human resources improvement in the form of training.

After the merger of PT Pelindo, PT Pelindo Terminal Petikemas became one of the sub-holding companies in containers. In maintaining consistency with the implementation of Occupational Health and Safety (OHS) after the merger, PT Pelindo Terminal Petikemas needs to understand the importance of safety leadership, safety culture, safety behavior, and safety perfor­mance in the OHS program's success. The study aimed to determine the effect of safety leadership on safety culture and safety performance, the effect of safety culture and safety behavior on safety performance, and safety behavior to act as a mediation between safety leadership and safety performance, and safety culture on safety performance at PT Pelindo Terminal Petikemas. The samples of 130 employees are then analyzed using Structural Equation Modeling (SEM) with SmartPLS software. The results showed that safety leadership has a significant effect on safety culture and safety performance. Safety culture and safety behavior have a significant effect on safety performance. Safety behavior can mediate between safety culture and performance, while safety behavior cannot act as a mediation between safety leadership and performance. This research implies that PT Pelindo Terminal Petikemas's management can select several strong and trustworthy employees from each terminal who merge to lead initiatives regarding company safety and communicate with the central command.
