ANALISA OPTIMASI WAKTU DAN BIAYA DENGAN MENGGUNAKAN METODE DURATION COST TRADE OFF PADA PROYEK PEMBANGUNAN PENANGANAN ROB ERETAN KABUPATEN INDRAMAYU JAWA BARAT

Abstract

In the planning of construction work, various things can happen in the implementation of construction projects which can cause an increase in implementation time so that the completion of the project becomes late. Delays in project work can be anticipated by accelerating implementation, but still paying attention to cost and quality factors. This study analyzed the acceleration of project duration in the implementation of the Indramayu Regency Eretan ROB Handling Development Project with the addition of working hours (overtime) which varied from 1 hour of overtime to 3 hours of overtime and with the addition of manpower using the time cost trade off method. From the normal cost of Rp. 20,778,458,753 and a duration of 307 days with the analysis of the time cost trade off method, it was concluded that the most efficient addition of overtime hours was the addition of 3 hours of overtime with a cost of Rp. 20,275,217,792 for a duration of 244 days and for the most efficient addition of labor was the addition of manpower to 3 hours of overtime work at a cost of Rp. 20,295,750,961 durations of 244. So that the results of the most efficient analysis are by adding 3 hours of overtime work with a difference from the normal cost of Rp. 503,240,961 and with a difference in duration of 63 days from the normal duration.
