Analysis Of Labor Productivity In Ironwork Floor Plate For Main Substation Construction Project For Cable Lines High Voltage At BKMS – JIIPE

Abstract

Productivity is an important factor in carrying out construction work. The level of labor productivity is directly proportional to the amount of work that can be completed; the higher the productivity, the faster the work can be completed. In floor slab installation work that has a large volume and requires a lot of labor, optimizing productivity is an important step to reduce costs and implementation time in order to obtain maximum results. This study uses the Work Sampling method through direct observation in the field to obtain data on labor, time, and work volume in the floor slab reinforcement installation process. Data collection was carried out during normal working hours at 08.00–16.00 with a break time at 12.00–13.00, without involving overtime. The data obtained were then processed to calculate labor productivity and compared with the standards set out in PUPR Ministerial Regulation No. 8 of 2023. The results showed that the average productivity in the field for reinforcement work reached 687.637 kg/OH, while the productivity value based on the analysis according to PUPR Ministerial Regulation No. 8 of 2023 is 400 kg/OH. The comparison shows that the average productivity in the field is 1.719 times higher than the applicable standard.
