ANALISIS PERBANDINGAN EFISIENSI PRODUKTIVITAS TOWER CRANE STUDI KASUS : PEMBANGUNAN GEDUNG FAKULTAS KEDOKTERAN GIGI UNIVERSITAS BRAWIJAYA

At this time the construction of high-rise buildings in big cities has been increasingly developed so that its implementation must be planned, one of which is planning in the selection of heavy equipment to help smooth the implementation of work in the field. field. Heavy equipment commonly used in the construction of multi-storey buildings is a tower crane. Tower cranes are very suitable for use in building services to serve the construction area because it has the ability lifting, shifting (trolleying), holding the load above when necessary or carrying the load to a specified place. the load above when necessary or carry the load to the specified place (slewing and travelling) so that the material mobilization of a construction project can run with the help of this heavy equipment. run with the help of this heavy equipment.
Analysis method This research was collected in the form of raw or unprocessed data. Then the original data (primary) is calculated theoretically using other types of tower crane specification data.
Based on the data and the results of the calculation analysis carried out on one of the research tower cranes Zoomlion TC 6250-10E is more effective than the existing XGT 160 C tower crane. This can be seen from the comparison of cycle time with a difference of 0.08%. the difference in productivity is 18.88 m3/hour and from the cost difference of Rp. 259.727.059
