Abstract
Proyek perbaikan gedung laboratorium Teknik Industri
ITS merupakan pembangunan gedung setinggi 7 lantai dengan
menggunakan metode cor ditempat (Cast in situ). Dengan
volume pekerjaan pembetonan gedung yang besar dan tipikal
ada kemungkinan lebih tepat bila digunakan metode precast
dari segi biaya. Hal tersebut karena penggunaan metode
pracetak dapat mengurangi biaya pemakaian bekisting atau
formwork, mereduksi biaya upah pekerja, dan mengurangi
durasi pelaksanaan proyek yang membuat biaya tidak langsung
proyek menjadi lebih kecil. Oleh karena itu, pada tugas akhir ini peneliti ingin membandingkan antara metode cast in situ dan metode pracetak, mana yang lebih optimal dalam
pelaksanaan proyek pembangunan tersebut.
Analisa biaya dilakukan dengan menghitung
komponen biaya langsung dari metode pracetak. Setelah
didapat hasil analisa biaya dari metode pracetak, hasilnya
dibandingkan dengan komponen biaya bila digunakan metode
cor ditempat. Kemudian, ditentukan mana yang paling optimal
untuk dipakai beserta hasil analisa biaya konstruksi yang
diperoleh. Analisa lain yang dilakukan adalah analisa waktu.
Setelah diperoleh komponen biaya dan waktu pracetak
kemudian di trade off untuk menentukan metode mana yang
lebih baik.
Dari hasil analisa diperoleh perbandingan total biaya
metode konvensional sebesar Rp 9.363.410.000,00 dengan
masa konstruksi 92 hari kerja sedangkan, metode pracetak Rp
9.656.630.000,00 dengan masa konstruksi 56 hari kerja.
Sehingga kesimpulan yang didapat metode pracetak membuat
biaya naik sebesar 3,1 % dan pengurangan waktu sebesar 40 %
dari metode cor ditempat.

The improvement of Industrial Engineering laboratory ITS is a 7-floor building using Cast in situ method. With a large and typical building construction work volume there is a better possibility when a precast method is used in terms of cost. This is because the use of precast methods can reduce the cost of using formwork, reduce the cost of workers' wages, and reduce the duration of project implementation which makes the project indirect costs less. Therefore, in this final project, the researcher wants to compare between cast in situ method and precast method, which is more optimal in the implementation of the development project.
The cost analysis is done by calculating the direct cost component of the precast method. Having obtained the cost analysis results from precast method, the result is compared with the cost component when cast method is used in place. Then, it is determined which one is most optimal to use along with the result of the analysis of construction cost obtained. Another analysis is the time analysis. Having obtained the cost component and precast time then in trade off to determine which method is better.
The result of comparative analysis total cost of conventional method Rp 9,363,410,000,00 with period of construction 92 working days whereas, precast method Rp 9.656.630.000,00 with period of construc tion 56 working days.
So, the conclusion is precat method make cost more higher 3.1% and reduction of project duration 40% from the cast in site method.
