ABSTRACT

Marunda is an area in North Jakarta which has a dry bulk port in Indonesia. One of the dry bulk ports in Marunda is Karya Citra Nusantara Port. In unloading activities there are constraints on the speed time so it will have an impact on berthing time and delivery goods. The existence of the KCN Port is to reduce dwelling time at Tanjung Priok Port. KCN port can unload coal for 2 to 3 days, this unloading is expected to be faster so it can reduce unloading costs. This research will examine the factors that can affect coal unloading time using multiple linear regression methods with cycle time as dependent variable and independent variables are idle time, total load, excavator production year,and weather. The results of the linear regression model on the entirebarge were Y = -24.856 + 1.076 JM – 0.630 TPE – 0.437 CA.
