abstract={The construction industry in Indonesia has experienced significant growth in recent years. One of the major ongoing projects is the Jakarta MRT Phase 2, which extends from the already operational Phase 1, spanning approximately 16 kilometers since March 2019. Phase 2 is divided into two segments, 2A and 2B, with CP203 being part of Phase 2A.
This study focused on implementing high discipline standards through the 5S methodology to enhance safety, health, and quality performance. Prior to the implementation of 5S in 2022, Extra-Process (39%) and Defect (29%) were the most common waste types occurred. However, as of January 2025, these issues have been completely eliminated. Awareness campaigns and management training have contributed to the development of an activity tracker, further strengthening the progress achieved.
With a workforce of 754 individuals, including contractors and consultants, and a project duration of 1,165 days, the initiative has successfully maintained a record of 1,165 days without any lost time incidents or reported cases. The findings demonstrate 5S’s effectiveness in minimizing waste and mitigating risks while aligning with Lean principles to optimize “Safety, health, and quality.” },
