Abstract

This study discusses the importance of scheduling in construction projects, particularly the application of the Precedence Diagram Method (PDM) and the Program Evaluation and Review Technique (PERT) to enhance time efficiency and identify critical activities. Project scheduling is a key element that ensures the project progresses according to plan and is completed on time. PDM serves to illustrate the sequence and interrelationships between activities through node representation, allowing the identification of the critical path. Meanwhile, PERT uses a probabilistic approach with three time estimates to anticipate variations and uncertainties in activity durations. A case study of a health center construction project in Banteang Regency demonstrates that the application of PDM and PERT, compared to the S-curve method, can optimize resource allocation, minimize the risk of delays, and ensure scheduling efficiency. With the support of software like Microsoft Project, the implementation of these two methods is expected to improve project control and ensure timely completion.

Abstrak

Penelitian ini membahas pentingnya penjadwalan dalam proyek konstruksi, khususnya penerapan metode Precedence Diagram Method (PDM) dan Program Evaluation and Review Technique (PERT) untuk meningkatkan efisiensi waktu dan identifikasi kegiatan kritis. Penjadwalan proyek merupakan elemen kunci yang memastikan proyek berjalan sesuai rencana dan selesai tepat waktu. PDM berfungsi untuk menggambarkan urutan dan keterkaitan antar kegiatan melalui representasi node, sehingga memungkinkan identifikasi jalur kritis. Sementara itu, PERT menggunakan pendekatan probabilistik dengan tiga estimasi waktu untuk mengantisipasi variasi dan ketidakpastian dalam durasi kegiatan. Studi kasus pembangunan puskesmas di Kabupaten Banteang menunjukkan bahwa penerapan metode PDM dan PERT, dibandingkan dengan metode kurva-S, dapat mengoptimalkan alokasi sumber daya, meminimalisir risiko penundaan, dan memastikan efisiensi penjadwalan. Dengan dukungan software seperti Microsoft Project, penerapan kedua metode ini diharapkan dapat meningkatkan pengendalian proyek dan memastikan penyelesaian yang tepat waktu.
