Setiawan, Dimas Rizki and Ir. Ihwan Hamdala, ST., MT., IPM. (2024) Analisis Percepatan Proyek Pembuatan Quench Column dengan Metode Time Cost Trade Off di PT Puspetindo. Sarjana thesis, Universitas Brawijaya.
Abstract
Proyek manufaktur merupakan rangkaian proses yang melibatkan produksi atau pembuatan dari suatu produk. Proyek manufaktur mencakup aktivitas perencanaan, pelaksanaan dan pengawasan proses produksi agar sesuai dengan spesifikasi dan permintaan. PT Puspetindo merupakan salah satu perusahaan manufaktur yang memproduksi berbagai macam peralatan penunjang industri seperti boiler, pressure vessel, rotary, agitator, dan lain sebagainya. Pada tahun 2022 PT Puspetindo menerima pesanan pembuatan quench column untuk proses produksi PVC. Proyek ini direncanakan selesai pada tanggal 25 Juni 2023, namun pada realisasinya mengalami keterlambatan selama 30 hari. Akibatnya perusahaan harus membayarkan denda keterlambatan sebesar 3% dari nilai proyek (0,1% setiap satu hari keterlambatan). Penelitian ini dilakukan untuk menganalisis dan membandingkan biaya serta durasi proyek pada kondisi normal dan dengan percepatan. Metode PDM (Precedence Diagram Method) digunakan untuk mengetahui jalur kritis proyek, dimana aktivitas pada jalur tersebut yang akan dilakukan percepatan. Opsi percepatan proyek yang digunakan adalah penambahan jam kerja atau lembur. Percepatan proyek akan menambah biaya langsung, sedangkan akan mengurangi biaya tidak langsung dan denda akibat keterlambatan. Oleh karena itu dilakukan analisa percepatan yang optimal dengan metode TCTO (Time Cost Trade Off). Hasil penelitian ini adalah proyek pembuatan quench column dapat diselesaikan selama 111 hari, atau dipercepat 10 hari dari durasi normal 121 hari. Percepatan tersebut menyebabkan bertambahnya biaya langsung sebesar Rp.28.585.058 akibat penambahan jam kerja, berkurangnya biaya tidak langsung sebesar Rp. 7.917.683, dan berkurangnya denda yang harus dibayarkan sebesar Rp. 72.000.000. Sehingga total biaya proyek akibat percepatan berkurang sebesar Rp. 51.332.625 dari biaya normal sebesar Rp. 6.510.857.536 menjadi Rp. 6.459.524.911.
English Abstract
A manufacturing project is a series of processes that involve the production or manufacture of a product. Manufacturing projects include planning, implementing and supervising production processes to meet customer specifications and requests. PT Puspetindo is a manufacturing company that produces various kinds of industrial supporting equipment such as boilers, pressure vessels, rotaries, agitators, and so on. In 2022 PT Puspetindo received an order to make a quench column for the PVC production process. This project was planned to be completed on June 25 2023, but its realization was delayed by 30 days. As a result, the company must pay a late fine of 3% of the project value (0.1% for every day of delay). This research was conducted to analyze and compare the costs and duration of projects under normal and accelerated conditions. The PDM (Precedence Diagram Method) method is used to determine the project's critical path, where activities on that path will be accelerated. The project acceleration options used are additional working hours or overtime. Accelerating projects will increase direct costs, while reducing indirect costs and fines due to delays. Therefore, an optimal acceleration analysis was carried out using the TCTO (Time Cost Trade Off) method. The results of this research are that the quench column construction project can be completed in 111 days, or accelerated by 10 days from the normal duration of 121 days. This acceleration resulted in an increase in direct costs of Rp. 28,585,058 due to additional working hours, a reduction in indirect costs of Rp. 7.917.683, and a reduction in fines that had to be paid by Rp. 72,000,000. So the total project cost due to acceleration is reduced by Rp. 51.332.625 from the normal cost of Rp. 6.510.857.536 to Rp. 6.459.524.911.
