Abstract

Penjadwalan proyek merupakan salah satu aspek penting dalam pengendalian waktu dan biaya pelaksanaan proyek. Penelitian ini bertujuan membandingkan metode Critical Path Method (CPM) dan Project Evaluation and Review Technique (PERT) pada penjadwalan fabrikasi Double Bottom dan Lower Mega Block Inner 02 struktur Topside Offshore Wind Farm Converter Station, serta menganalisis pengaruhnya terhadap biaya proyek. Analisis dilakukan menggunakan metode CPM dan PERT berdasarkan hubungan ketergantungan aktivitas. Hasil penelitian menunjukkan bahwa metode CPM menghasilkan durasi proyek selama 367 hari dengan lintasan kritis ID 3–4–8–13–18–23–27, sedangkan metode PERT menghasilkan Expected Project Duration selama 372,67 hari. Analisis probabilitas menunjukkan peluang penyelesaian proyek sebesar 0,22% pada target 367 hari, 76,73% pada target 378 hari, 92,22% pada target 383 hari, dan 98,21% pada target 388 hari. Total biaya proyek metode CPM sebesar Rp73.325.443.198,55, sedangkan metode PERT sebesar Rp73.599.793.880,36, dengan selisih 0,37%. Berdasarkan hasil tersebut, metode CPM lebih efisien dari sisi waktu dan biaya, sedangkan metode PERT memberikan estimasi durasi yang lebih mempertimbangkan ketidakpastian aktivitas.

Project scheduling is one of the most important aspects of controlling project time and cost. This study aims to compare the Critical Path Method (CPM) and the Project Evaluation and Review Technique (PERT) for scheduling the fabrication of the Double Bottom and Lower Mega Block Inner 02 structures of the Topside Offshore Wind Farm Converter Station, as well as to analyze their impact on project cost. The analysis was conducted using the CPM and PERT methods based on the precedence relationships among project activities. The results show that the CPM method produced a project duration of 367 working days with a critical path consisting of activities ID 3–4–8–13–18–23–27, while the PERT method resulted in an Expected Project Duration of 372.67 working days. Probability analysis indicated project completion probabilities of 0.22% for a target duration of 367 working days, 76.73% for 378 working days, 92.22% for 383 working days, and 98.21% for 388 working days. The total project cost estimated using the CPM method was IDR 73,325,443,198.55, whereas the PERT method resulted in a total cost of IDR 73,599,793,880.36, representing a difference of 0.37%. Based on these findings, the CPM method is more efficient in terms of project duration and cost, while the PERT method provides a more realistic duration estimate by accounting for uncertainty in activity durations.
