- Concrete iron produced by PT. Hanil Jaya Steel still has product defects in the form of line defects, village defects, nguping defects and flattened tip defects of 3.22%. The company wants to control the quality of this concrete iron, thereby reducing product defects. This study aims to determine the level of quality of concrete iron and provide suggestions for improvement to reduce disability. The results of this study are the level of product quality during the month of July-December 2017 at the level of sigma 3.9202 with DPMO of 8059.83. In July-December there were several types of concrete iron product defects, namely line defects of 61.873%, kampong defects of 20.3365%, flattened tip flaws of 10.707%, and earning defects of 7.055%. Factors that cause product defects are Human, Machine, Environment. Proposed improvements with the Kaizen method that can be used as a basis for quality improvement efforts, namely at the Seiketsu (maintenance) and Shitsuke (habituation) stages.
