Implementasi Metode Six Sigma Untuk Menurunkan Cacat Produk Pada Ukm Onetixs

Abstract

Product quality is a determining factor in customer satisfaction and trust in the products
produced. Product defects can cause losses to convection convection. Therefore, this study aims to
implementation of Six Sigma method to reduce product defects in Onetixs SMEs. Five stages are used
to improve product quality in Onetixs convection, namely Define, Measure, Analyze, Improve, and
Control (DMAIC). The results of research on Onetixs convection obtained the type of defect in Onetixs
shoes based on the pareto diagram of the highest defects caused by glue stains. Another type of defect
is caused by non-sticky soles, and poorly sewn seams. Of the 1040 samples observed, there were 146
defective products caused by 30% non-adhesive sole defects, 38% glue stain defects, and 32% untidy
seam defects. Furthermore, the DPMO value of attribute data obtained is 46795 and is at the level of
3.18 sigma. Based on the causes of defects obtained from the fishbone diagram, the proposed
improvements given to reduce defects due to glue stains are to improve the quality of work during the
shoe gluing process, pay attention to the quality of the glue mixture, pay attention to the quality of the
mixture of glue and tools used for gluing, improve the method of gluing, periodically check shoes
