ANALISA EFISIENSI WAKTU KERJA DAN BIAYA TERHADAP OPERASIONAL ALAT BERAT TOWER CRANE PADA PEKERJAAN PEMBANGUNAN STRUKTUR GEDUNG DPRD KOTA PADANG
Abstract
In the use of heavy equipment sala one tower crane certainly incurs costs. The reason is the range or how long the use of heavy equipment is therefore strategic time planning is needed by the contractor in order to avoid the problem of vacant time on the tower crane, such as minor damage to the tower crane, operator discipline and readiness, miscommunication between the loader and receiver workers, and other things that can cause the tower crane to have empty time, not doing anything. The purpose or purpose of this analysis of the efficiency of working time and costs for the operation of tower cranes is to determine the efficiency of working time and costs on tower cranes, to find out the more efficient results of tower crane analysis and to find out the work efficiency and time sheet costs of tower cranes. The type of research is divided or classified into two types, the first is qualitative research and quantitative research. From the calculation of the working time efficiency of the tower crane without idling 83.33% with an operational cost of Rp. 27,882,082.5 / hour. The efficiency of tower crane working time due to idle decreased to 66.46% with an operating cost of Rp. 22,579,017.454 / hour. The time sheet of the tower crane machine is 100% with an operating cost of Rp. 33,458,499 / hour.
