PENGARUH YARD OCCUPANCY RATIO TERHADAP PRODUKTIVITAS BONGKARMUAT PETIKEMAS DI TERMINAL DOMESTIK PT IPC TERMINAL PETIKEMAS AREA TANJUNG PRIOK

Abstract

This research is motivated by operational challenges at the Domestic Terminal of PT IPC Terminal Petikemas Area Tanjung Priok, where the realization of the Yard Occupancy Ratio (YOR) consistently exceeds the ideal critical threshold of 65% based on the Decree of the Head of the Main KSOP Office of Tanjung Priok Number HK.806/1/1/2025. This condition triggers a surge in non-productive re-handling activities, hinders daily operational workflows, slows down the rhythm of equipment work at the berth, and increases Truck Turn Around Time (TTAT). This study aims to quantitatively and empirically test and analyze the effect of YOR on container loading and unloading productivity. The research method used is a quantitative approach with data collection through structured questionnaires distributed to a sample of employees using a simple random sampling technique, supported by documentation and field observations. The results of the regression analysis show that YOR has a strong and significant negative effect on container loading and unloading productivity, confirming an inversely proportional relationship where an increase in yard density directly decreases berth productivity. Based on the coefficient of determination test, the contribution of YOR's influence on fluctuations in loading and unloading productivity is 60.1%, while the remaining 39.9% is influenced by other factors outside the study. These findings confirm that productivity variations are dominantly controlled by yard density, making yard stack utility management a vital key strategy in maintaining terminal productivity stability.
