Pemasangan Komponen (PMK) Bogie workshop at PT INKA is a workspace on which all bogie, produced by PT INKA, is being assembled. The workshop convenes all type of bogie which arrived as a set of component and main bogie frame into a finished bogie unit. Therefore the harmonious sequence of processes on this workshop is crucial for the company's productive capacity. Be that as it may, the workshop productive capacity is considerably low, around two-unit produced per day (in an ideal condition). This is by the cause of the lack of optimization of processes and materials flow. The most noticeable waste is waiting and fixing defects. By adopting lean production system, productivity would increase significantly (as in the case of Toyota production line). This is achieved by eliminating all identified waste (MUDA) dan continuously executing improvement (kaizen). Assuming that the two ladder condition is carried out steadily, the two main pillars of lean production system is attainable, just-in-time and jidoka. Additionally, both pillars consist of their respective main concept (i.e., pull-system, decrease overall takt-time, processes distribution, and quality production). Those individual main concept, each require certain special cognition (concrete technique) to be executed. Identifying wastes and implementing improvements in the PMK Bogie workshop is the main goal for this final paper. As currently productive capacity is around 14 units per week (including extra manhour). While ideally, 41 units for the first week and 50 units for the second week and so forth, is feasible.
