Analisis Percepatan Waktu Dan Biaya Proyek Konstruksi Dengan Penambahan Jam Kerja (Lembur) Menggunakan Metode Time Cost Trade Off : Studi Kasus Proyek Pembangunan Prasarana Pengendali Banjir

Abstract

Time and cost have significanteffect on the success and failure of the projects.The
benchmark for the success project is usually seen by short finishing time with the
minimum cost without leaving the quality.Project management systematically is
required to ensure the project implementation time in accordance with the contract
or even faster so the cost can provide benefits, and also avoid the penalty due to
delay in the completion of project. The aim of this research is to calculate the
changes of the cost and (overtime) and to compare the results between the cost of
penalty cost with the changes after adding the overtime.The secondary data
obtained from the contractor.Data analysis in this research is using Microsoft
Project 2007 program and methods of time cost trade off. The results of the
program Microsoft Project 2007 is the critical path and the results of the method of
time cost trade off is duration acceleration and cost increases due to the acceleration
of the duration in any activities that increased.The results of this study indicate that:
(1) From the time cost trade off with the addition of 1 hours of work per day
conducted on first day on critical jobs during the project, obtained the reduction in
the duration of 57 days, from the normal duration of 196 days to 139 days with a
total project cost changes from the normal cost of Rp 16,371,654,833.56 to Rp 16
133 .588.292,57 (the difference between the cost of Rp. 238,096,540.99) as well as
causing an increase in the direct cost of Rp 15,469,452,846.76 to Rp
15,493,731,373.36 (the difference between the cost of Rp. 24,278,526.60) and
indirect costs experienced a decrease of US $ 902,201,986.80 to Rp 639,826,919.21
(the difference between the cost of Rp. 262,375,067.59), (2) cost of accelerating the
duration of the project with overtime is cheaper than the cost to be incurred if
projects experienced delays and penalty.
