Abstract

This descriptive research was conducted with a qualitative approach. The study included three MSMEs of convection in Kudus because Muslimah clothing convection in Kudus is increasing. However, in the production process, several defective products are still found. The existence of these defects indicates the presence of waste in the production process. Therefore, the purpose of this research was to find out the causes of defects in the production process and take corrective steps to reduce defects. Based on the waste identification that has been done, the most critical waste defects are selected using the AHP questionnaire. Then the DPMO calculation was carried out, which showed the sigma level value for the three MSMEs, namely 3.75, 3.57, and 3.64. Next, the root causes of waste was analyzed using fishbone diagrams and FMEA tables. Recommendations for improvements are given to reduce the occurrence of these root causes. If the recommendations for improvement are implemented, there will be an increase in the sigma level for the three MSMEs, namely 4.02, 4.19, and 3.97. Keywords: convection, lean six sigma, defect, waste

通过应用精益六西格玛法减少浪费生产对库德斯对流微型、小型和中型企业（MSMEs）的影响分析

这项描述性研究采用定性方法进行。研究对象包括库都斯的三家对流微小中型企业，因为库都斯的穆斯林服装对流正在增加。然而，在生产过程中，仍发现了一些次品。这些缺陷的存在表明生产过程中存在浪费。因此，本研究的目的是找出生产过程中出现缺陷的原因，并采取纠正措施减少缺陷。根据已完成的浪费识别，使用 AHP 问卷选出了最关键的浪费缺陷。然后进行 DPMO 计算，结果显示三家中小微企业的西格玛水平值分别为 3.75、3.57 和 3.64。接着，使用鱼骨图和 FMEA 表格分析了造成浪费的根本原因。为减少这些根本原因的发生，提出了改进建议。如果改进建议得以实施，三家中小微企业的西格玛水平将有所提高，分别为 4.02、4.19 和 3.97。关键词：对流、精益六西格玛、缺陷、浪费
