ANALISIS PRODUKTIVITAS KOMBINASI CONCRETE PUMP DAN TRUCK MIXER PADA PROYEK PEMBANGUNAN BALI INTERNATONAL HOSPITAL SANUR

Abstract

The phenomenon of the use of heavy equipment concrete pumps and truck mixers in the field and seen from the considerable differences in the previous research, this study was conducted to find out: .The results of this analysis are (1) Truck mixer with a total of 6 fleets pumped using a concrete pump long boom of 70.35 m3/hour, Truck mixer with a total of 6 fleets pumped using a standard concrete pump of 80.70 m3/hour, Concrete pump longboom 30.86 m3/hour, Standard concrete pump 32.05 m3/hour, Combination of 12 truck mixer fleets with 2 Concrete pump is planned to be 100 m3/hour and the realization is 62.88 m3/hour. (2) the comparison of the planned productivity (100 m3/hour) with the realization (62.88 m3/hour) using a combination of 2 concrete pumps and 12 truck mixers, the duration required for LINAC wall casting with a volume of 540 m3, which is for 8.9 hours and the operational cost of the realization tool (Rp. 12,160,960.00) is greater than the plan (Rp. 7,651,840.00.) It is recommended to use an alternative combination of 3 concrete pumps and 12 truck mixers with the results of a productivity analysis of 94.5 m3/hour with a faster duration (5.7 hours) and a lower cost (Rp 11,703,216.00)
