Abstract

The process of loading and unloading ships is a critical activity in the logistics chain that impacts the efficiency and operational costs of ports. This study aims to evaluate the use of Network Planning methods in planning and controlling the time of the ship loading and unloading process. The research was conducted using historical data on the loading and unloading times of ships, as well as related activity schedules at Semayang Port, Balikpapan. This study adopts an approach by analyzing the application of network planning on the unloading process of the MV Future Ocean 14,514 DWT ship in the form of an S-Curve, then analyzing alternative critical paths along with duration acceleration using the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) on days (conditions) with better work weight consistency. Additionally, it analyzes how this affects manpower and manhour efficiency. The results of this study indicate that the application of the CPM and PERT methods led to a reduction in job duration from 1.408 minutes to 1.227 minutes using CPM, and 1.224,67 minutes using PERT. Based on the duration acceleration, the need for additional manpower increased from 21 to 24, resulting in a -14% decrease in manpower efficiency. The total manhour value changed from 3.941,28 MH to 3.936 MH with a 0,13% increase in manhour efficiency for CPM, and 3.916,8 MH with a 0,62% increase in manhour efficiency for PERT.
