Abstract
In facing the dynamics of the railway industry that demands high efficiency, manufacturing companies such as PT Industri Kereta Api (Persero) must optimize their production processes to reduce production cycle times. This research aims to identify and reduce waste in the Bogie production line through a Lean Manufacturing approach using Value Stream Mapping (VSM) and the E-Kanban system. The research focuses on eliminating waste such as overproduction, waiting, excess inventory, and overprocessing that significantly hinder production flow. The research stages began with mapping the current condition (Current State VSM), identifying activities using Process Activity Mapping (PAM) as part of the Value Stream Analysis Tools (VALSAT), and designing improvement proposals through an E-Kanban system integrated with a SQL database and a real-time dashboard. The results showed that the proposed improvement was able to reduce production lead time from 3,480 minutes to 2,985 minutes, representing a time savings of 495 minutes. The effectiveness of these improvements is mapped in the Future State VSM, which successfully increased the Process Cycle Efficiency (PCE) value significantly from 75.8% to 88.4%. This research provides a tangible contribution to production floor management digitalization and operational efficiency improvement for bogie manufacturing at PT Industri Kereta Api (Persero).
