| dc.description.abstract | PT Yamaha Indonesia is a manufacturing company that produces pianos and has a program in
place to periodically increase its productivity. The production process which is mostly done
manually, is a challenge, especially for operators because they play an important role in
achieving productivity targets. In the Final Regulation UP group, several problems occur,
making it impossible to achieve the productivity target. The problems in this group are the
excessive number of operators, below-target production outcomes, and a high number of
reworked products. Therefore, it is necessary to find out the effectiveness of this working group
using the Overall Labor Effectiveness (OLE) method. Then it will continue with an analysis of
the results using the Root Cause Analysis (RCA) tools, which will then be given kaizen or
suggestions to solve existing problems. Following that, the findings will be analyzed using Root
Cause Analysis (RCA) tools, and kaizen, or recommendations for solving current issues will be
provided. The Overall Labor Effectiveness (OLE) value of the Final Regulation UP working
group during 34 days of observation was 79% with a value availability ratio of 96%,
performance ratio of 97%, and quality ratio of 85%, the OLE score is below the international
standard due to the lower quality ratio. After kaizen was implemented, the OLE score increased
to 89% with the value obtained from the variables 98% for the availability ratio, 98% for the
performance ratio, and 92% for the quality ratio. All of the three variables are increased, making
the OLE score higher than before. | en_US |
