STUDI OPTIMASI BIAYA DAN WAKTU MENGGUNAKAN METODE DURATION COST TRADE OFF PADA PROYEK PEMBANGUNAN HOTEL THE KARANIE YOGYAKARTA
Abstract
In the construction project planning, time and cost greatly affect the success and
failure of a project. The implementation of a construction project is a sequence of
interdependent activities between one job and another.. The way in this study is to
add working hours (overtime) and add labor so that the results of both will be
compared. The method used is Duration Cost Trade Off Method with the help of
Microsoft Project 2013 Application. From the research conducted, for the addition
of overtime 1 hour decreased by Rp 174,235,266,01 and change the duration
decreased 25,52 days. For 2 hours overtime decreased by Rp 245,832,845.81 and
change in duration decreased 44.10 days. For the addition of overtime 3 hours
decreased by Rp 284.300.094,81 and change of duration decreased 58,06 days.
While for the addition of labor for 1 hour decreased by Rp 227,595,692.52 and
change the duration decreased 25.52 days. For the addition of labor for 2 hours
decreased by Rp 393,530,743,96 and change of duration decreased 44,10 days. For
the addition of workforce for 3 hours decreased by Rp 518,173,771,93 and change
of duration decreased 58,06 days. From the analysis performed the most optimal
results occur when the addition of workforce for 3 hours is Rp 10.898.716.933.09
and the duration of acceleration to 91.94 days.
