Quality Improvement Using The DMAIC Method In The Light Brick Industry

Abstract

Background: The growing industrialised world will lead to more rivalry. Companies who are able to compete are able to maintain the quality of their products to ensure client happiness. Consequently, quality control is required.

Methods: This study focuses on decreasing red brick product faults at PT. Surya Rezeki Timber Utama using the Six Sigma-DMAIC method (Define, Measure, Analyze, Improve, and Control).

Result: The result shows a 6.59% decrease in defects/rejects from 28.71% defects/rejects produced by AAC (Autoclaved Aerated Concrete), accompanied by a decrease in the DPMO value from 13,660.26 PPM to 2,912.66 PPM and an increase the sigma value of 3.7069 to 4.2575.

Conclusion:The effects of the examine segment the use of a fishbone diagram decide the reasons of the defect/ break, such as: personnel do now no longer understand fine standards, product inspection isn't always implemented, people do now no longer understand paintings procedures, device overall performance is unpredictable, people are careless, the range of milling is unknown, and brick
