PERBANDINGAN BIAYA DAN WAKTU STRUKTUR BETON SISTEM KONVENSIONAL DAN SISTEM PRECAST PADA PEMBANGUNAN GEDUNG PUSKESMAS JERUK LEGI KABUPATEN CILACAP

Abstract

Currently, building construction planning has developed, including the precast system. A precast system is a system where some or all of the components are printed first in a factory or other place outside the project location according to their size and then placed and installed in the planned place. The conventional system is a system where all structures that use concrete construction, the concrete is cast directly on the spot.The aim of this research is to determine the cost of concrete construction when using conventional concrete construction systems and precast systems and to determine the time required for work from both systems. The method used in this research is qualitative descriptive research. The data in this research is secondary data in the form of supporting data collected through literature studies taken from literature, previous writings, data from the internet and so on. This secondary data is to obtain institutional data, this data is obtained from related parties, one of which is the Project Cost Budget Plan.From the results of calculations and data analysis that have been carried out, it is found that the total cost of implementing a conventional concrete system is IDR 327.868.106,03, while the total cost of implementing a precast concrete system is IDR. 380.058.394,38. The time difference between the two systems is 11 days. The comparison results of the two systems show that the costs for renting heavy equipment such as cranes are large, but in terms of time efficiency, the precast system is faster to implement than the conventional system because the components can be made or ordered before the construction project is implemented.
