Abstract

Pembangunan infrastruktur ketenagalistrikan Transmisi 150 kV oleh PT PLN (Persero) merupakan penugasan dari Pemerintah dalam rangka mendukung pertumbuhan listrik di Indonesia. Beberapa proyek Transmisi 150 kV mengalami keterlambatan dalam penyelesaian proyek dikarenakan kurang akuratnya dalam penentuan waktu dan biaya penyelesaian proyek, hal ini terlihat dari waktu penyelesaian proyek lebih lama daripada waktu kontrak.Proyek pembangunan transmisi 150 kV terdiri dari aktivitas engineering, procurement, construction dan commissioning sehingga diperlukan perhitungan waktu dan biaya yang matang dengan mempertimbangkan sumber daya (Man, Material, Machine dan Method). Pendekatan metode Critical Path Method (CPM) digunakan dalam analisis waktu dikarenakan bersifat deterministik dan metode Time Cost Trade Off (TCTO) digunakan ketika ada potensi permasalahan keterlambatan, percepatan maupun pembengkakan biaya proyek. Kombinasi pendekatan metode CPM dan TCTO tepat digunakan pada aktivitas proyek yang diketahui pasti dengan tetap memperhatikan pekerjaan paralel dan serial. Dari hasil penelitian bahwa proyek transmisi 150 kV terdapat 13 lintasan kritis dimana aktivitas kritis yang tidak mempunyai total slack (float = 0), skema percepatan yang berdampak besar terhadap waktu dan biaya yaitu percepatan pada tahap construction serta perubahan seluruh variabel sumber daya (Man, Material, Machine dan Method) berdampak terhadap perubahan waktu dan biaya, sedangkan perubahan salah satu variabel sumber daya yaitu Method berpengaruh terhadap waktu namun belum tentu berpengaruh terhadap biaya.

The construction of the 150 kV Transmission electricity infrastructure by PT PLN (Persero) is an assignment from the Government in order to support electricity growth in Indonesia. Several 150 kV Transmission projects experienced delays in project completion due to inaccurate timing and project completion costs, this can be seen from the project completion time being longer than the contract time. The construction project of the 150 kV transmission involves engineering, procurement, construction, and commissioning activities, requiring careful calculations of time and costs while considering resources (Man, Material, Machine, and Method). The Critical Path Method (CPM) is used as the deterministic analysis approach for time analysis, while the Time Cost Trade-Off (TCTO) method is employed when there is a potential for project delays, acceleration, or cost overrun. The combination of the CPM and TCTO methods is suitable for project activities that are precisely known, while considering both parallel and serial work. Based on the research results, the 150 kV transmission project has 13 critical paths, where critical activities have no total slack (float = 0). The acceleration scheme that significantly impacts time and cost is the acceleration during the construction phase, and changes in all resource variables (Man, Material, Machine, and Method) affect both time and cost. However, a change in a single resource variable, namely Method, may impact time but not necessarily cost.
