Abstract

Project delays are a highly unenviable condition. A school project in Waesama Sub-district, Buru Selatan Regency was delayed where 208 days of planning were not achieved, and were realized more than the plan. This study aims to distinguish the duration of the project using CPM and PDM on the project, as well as determine the optimal duration between the two methods. As well as obtaining critical jobs for CPM and PDM. CPM (Critical Path Method) is an AON (Activity on Node) method that only has one constrain, namely FS (Finish to Start). While PDM (Precedence Diagram Method) is an AON (Activity on Node) method that has 4 constrains FS (Finish to Start), SS (Start to Start), SF (Start to Finish), FF (Finish to Finish). The results of this comparative study found that there were differences in activities that were critical, there were also differences in duration after the use of these two methods. Where CPM produces a duration of 203 days, while PDM produces the most optimal duration of 200 days because it saves 8 days more than the duration of project planning. The use of PDM methods were more effective.

Abstract

Construction projects are a series of activities related to the process of developing infrastructure within a predetermined time frame by estimating the time required to complete the project. Delays in project planning can occur due to various factors. This also happened in the construction of the Integrated Laboratory and Library Building Project at MAN 1 Central Maluku, which experienced delays caused by several factors, including delays in the project due to factors such as labor, materials, design, situation, equipment, finance, site characteristics, and external factors. However, the factors that significantly and dominantly influence the delays are not yet known. Therefore, the purpose of this research is to identify the significant and dominant factors causing project delays. The analytical method used is regression analysis, which includes T-tests and F-tests. Based on the research results, the significant factors influencing project delays are the lack of availability of labor (labor factor), delay in the delivery of materials (material factor), equipment productivity (equipment factor), and financial difficulties of the contractor (financial factor). The most dominant factor influencing project delays is the labor factor, with a beta value of 1.198, indicating a lack of labor availability.
