In order to reach the target plan on the Syamsuddin Noor International Airport Road Construction project, the contractor applied overtime working hours for the labor. The application of overtime working hours requires issues on budget. This overtime productivity measurement is useful to find out the effectiveness of the overtime working hour.One of the methods for measuring labor productivity is using the partial productivity approach, which can be measured by knowing the input and output values of the equation of partial production. For the calculation of labor productiveness of the Syamsuddin Noor Internasional Airport Access Road Construction project, the input value is the amount of time used per day, whereas the output value is the amount volume of work produced per day. The result from this analysis with a partial productivity approach found that the average productivity of normal working hours was 1661,87 m/hour for galam pile work and 17,83 m3/hour for embankment work. Furthermore, the average productivity of overtime hours was 2715,46 m/hour for galam pile work and 41,31 m3/hour for embankment work. The results show that overtime working hour productivity is higher than normal working hour productivity, which can be caused by some reasons. The main obstacle is rainy weather that requires work to be temporarily stopped and can only be continued when the rain stops or even sometimes have to wait for the site to be dry enough. The application of overtime working hours increases the wage budget by 30,38%. However, the overtime labor cost applied in the Syamsuddin Noor International Airport Access Road Construction project is not in line with the overtime labor cost based on provisions of PP Number 35 Year 2021.Keywords: Partial productivity, labor, overtime working hours, overtime labor cost.
