<span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">The increasing economic growth in Indonesia encourages the growth of SMEs (Small and Medium Enterprises). This <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">condition results in the intense competition among similar SMEs. This encourages companies to always produce quality <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">products in order to meet customers’ satisfaction. One of the methods to control the quality is by using Six Sigma. <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">Six sigma is a method of improving the quality towards the target of 3.4 failures per million opportunities for each <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">production of goods and services. Six sigma is divided into two methods, namely DMAIC (Define, Measure, Analyze, <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">Improve, Control) and DMADV (Define, Measure, Analyze, Design, Verify). Six Sigma can be implemented not only for <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">big companies but also for SMEs. This study was conducted to determine the application of quality control aspect of <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">Six Sigma in CV. Berkah Abadi as an SME in producing shoes under the name BNA. This study utilized DMAIC method. <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">By using Six Sigma, it can be seen that the sigma value in the production process of CV Berkah Abadi is 3,274 with the <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">possibility of error products contained is 38758.87 in a million occasions. In the application of Six Sigma in this study, <span style="color: #231f20; font-family: Calibri; font-size: 11pt; font-style: normal; font-variant: normal;">there are six causes of defective products, namely untidy glue application (41.7%), stains (23.8%), squiggled pattern <span>(11.9%), untidy stitches neat (10.4%), wrinkles (8.9%) and torn materials (2.9%).<br /></span></span></span></span></span></span></span></span></span></span></span></span>
