Abstract

The success of a project cannot be separated from a series of activities that include planning, implementation and supervision stages. In Time control on a project, it is very necessary for a project to be able to complete the project on time or earlier than planned. The time control method used in this study is the Supply Chain Collaboration, Integration and Relations method. This research was conducted on the PT XYZ Mining Facility Development Project, Mimika Regency, Papua which aims to find out the project performance and get solutions to the problems that occur in the mining facility construction project. The data used in this study are Time Schedule, Construction Plan, Worker Supply Plan and weekly progress report. The implementation of IoT technology in logistics processes significantly improves the efficiency and effectiveness of the supply chain. In the copper cleaner project, the application of IoT was able to reduce delivery delays by an average of 13% and increase the reliability rate of delivery (on-time delivery) to 85%.

Abstract

The Road Preservation Project on Liran Island has faced significant implementation delays. Liran Island, categorized as one of the 3T (terdepan, tertinggal, and terluar) areas, has encountered challenges mainly due to difficult geographical conditions. These challenges include shallow sea topography and shoals that hinder navigation, strong currents and tides that limit ship movement, adverse weather conditions such as high winds and large waves, and limited resources that require material imports from outside the island. This study aims to identify and analyze the geographical factors most influencing the optimization of costs and time in the project. The research design employs simulation of optimization scenario models, comparing geographical and normal conditions (without geographical factors). Data analysis is conducted using the Transportation Method for cost optimization (material procurement) and the Critical Path Method (CPM) for time optimization (rescheduling). The results reveal that geographical conditions significantly impact mobilization costs. Among the variables analyzed—sea topography (X1), sea and water conditions (X2), weather (X3), and natural resources (X4)—weather (X3), particularly wind speed and wave height, has the greatest influence on increasing distribution costs. Furthermore, geographical conditions also affect the project schedule, particularly in material delivery planning, which requires longer loading and unloading times. Adjusting the schedule based on geographical conditions leads to cost and time efficiencies, especially in choosing the right vessel types, estimating weather, and managing tidal conditions.
