Project Scheduling Evaluation Using the CPM (Critical Path Method) and PERT (Program Evaluation and Review Technique) Methods on the Reconstruction of the Buareno – Kadungrejo Road, Bojonegoro

Abstract

Construction project scheduling is a crucial part of project management that requires careful planning to complete the project on time and within the predetermined budget. The Baureno - Kadungrejo Road Reconstruction Project in Bojonegoro Regency faces various challenges in managing time and resources, leading to delays in the project's implementation. These issues are primarily caused by external uncertainties such as unpredictable weather conditions and limited available resources. To address these scheduling management problems, one effective method is the Critical Path Method (CPM). The CPM approach uses a deterministic method, meaning the data and assumptions used are reliable and definite. The data collected for this study includes project reports, direct field observations, and calculations performed using POM-QM software. By applying the CPM method, it is possible to obtain a clearer picture of the activity sequence, individual activity durations, and the critical path that most significantly influences the overall project completion time. This research aims to determine an optimal construction duration for the Baureno - Kadungrejo Road Reconstruction Project in Bojonegoro Regency. Based on the analysis and simulations conducted, the optimal duration for completing the project is 25 days. The project schedule, developed through network planning, also identified several activities on the critical path, specifically activities coded A, C, D, E, and F. These activities are the main factors affecting the project's completion time and need to be managed effectively to ensure the project finishes on schedule.
