Abstract

Penjadwalan proyek merupakan salah satu faktor penting dalam keberhasilan pelaksanaan proyek konstruksi. Penelitian ini bertujuan membandingkan hasil penjadwalan proyek konstruksi sipil Galangan Semarang menggunakan metode Critical Path Method (CPM) dan Precedence Diagram Method (PDM). Data yang digunakan berupa daftar aktivitas, durasi pekerjaan, dan hubungan ketergantungan antar aktivitas. Analisis dilakukan melalui penyusunan Work Breakdown Structure (WBS), jaringan kerja proyek, serta perhitungan Earliest Start (ES), Earliest Finish (EF), Latest Start (LS), Latest Finish (LF), dan float. Hasil penelitian menunjukkan bahwa metode CPM menghasilkan durasi proyek selama 117 hari dengan jalur kritis A–B–C–D–E–F–G–L–M–N–O–P–Q–R, sedangkan metode PDM menghasilkan durasi proyek selama 95 hari dengan jalur kritis A–B–C–D–G–H–M–N–O–P–Q–R. Metode PDM mampu mempercepat penyelesaian proyek sebesar 22 hari atau 18,8% dibandingkan CPM karena memungkinkan beberapa aktivitas dilaksanakan secara tumpang tindih (overlapping) melalui hubungan Start to Start (SS) dan Finish to Finish (FF). Berdasarkan hasil penelitian, metode PDM lebih efektif dibandingkan CPM dalam menghasilkan penjadwalan proyek yang lebih efisien pada proyek konstruksi sipil Galangan Semarang.

Project scheduling is one of the key factors in the successful execution of construction projects. This study aims to compare the scheduling results of the Semarang Shipyard Civil Construction Project using the Critical Path Method (CPM) and the Precedence Diagram Method (PDM). The data used consist of activity lists, activity durations, and dependency relationships among activities. The analysis was conducted through the development of a Work Breakdown Structure (WBS), project network planning, and the calculation of scheduling parameters, including Earliest Start (ES), Earliest Finish (EF), Latest Start (LS), Latest Finish (LF), and float. The results indicate that the CPM method produces a total project duration of 117 days with a critical path of A–B–C–D–E–F–G–L–M–N–O–P–Q–R, while the PDM method results in a total project duration of 95 days with a critical path of A–B–C–D–G–H–M–N–O–P–Q–R. The PDM method is able to accelerate project completion by 22 days or 18.8% compared to CPM because it allows several activities to be performed concurrently through Start-to-Start (SS) and Finish-to-Finish (FF) relationships. Based on the findings, the PDM method is more effective than CPM in producing a more efficient project schedule for the Semarang Shipyard Civil Construction Project.
