Abstract

The implementation of rigid pavement work on the Pekanbaru-Bangkinang toll road construction project uses two methods, namely, conventional and slipform concrete paver because it is influenced by the road width factor. The cost for the implementation of rigid pavement is more expensive than flexible pavement with a percentage of 33.63%, therefore it is necessary to control the time by looking at the process flow and identifying waste by using the Value Stream Mapping approach. This study aims to determine the difference in process flow, total cycle time and the resistance of rigid pavement work. The research method used is Value Stream Mapping. The research was conducted by direct observation and taking notes on work sampling. The results of observations are made in the form of Value Stream Mapping to determine the difference between process flow and total cycle time, work constraints are obtained from the work sampling results that cause Non Value Adding Activity Uncensarry. The results showed that there were different forms of Value Stream Mapping, the conventional method consisted of 10 types of work, namely, formwork work, plastic installation, dowel work, material mobilization, pouring work, spreading work, vibrating work, compaction work, finishing work and quality control work. While the slipform concrete paver method consists of 5 types of work, namely, plastic installation work, dowel work, material work, compaction work and quality control work. The total cycle time for the conventional method is 506.18 minutes and for the conversion of the slipform concrete paver method 175.32 minutes, so there is a difference of 330.47 minutes with a percentage of 65.33%. There are 3 obstacles in the process of implementing rigid pavement, namely, lack of workers in the field, project environmental conditions and weather.
