Abstract

Siti Koriah (41183402150057) Penggunaan metode six sigma sebagai alat pengendalian dan perbaikan kualitas di PT Wahana Duta Jaya Rucika. xi +80 halaman +18 tabel +11 gambar + 2 diagram + 7 lampiran Kata kunci : Pengendalian Kualitas, Six sigma, DMAIC, Produk Defect. Quality control is an important thing that needs to be done to minimize the occurrence of defect rates in products. Companies can minimize product defects by using the six sigma method, by formulating the Define, Measure, Analyze, Improve, Control (DMAIC) that occurs. The purpose of this research is to find out how to control quality at PT Wahana Duta Jaya Rucika and to identify the factors that cause product defects to provide recommendations for improvement plans for the factors that cause defects in products to improve product quality. The research method used is a quantitative descriptive approach using the six sigma method. In identifying the causes of defects using several tools, namely DMAIC (Define, Measure, Analyze, Improve, Control). Data collection techniques were carried out through interviews and observation. The results showed that the production data obtained for the total production from October 2020 to September 2021 was 838519 with the number of defective products that occurred in production of 2106 pipes which is the total number of product defects processed with DMAIC obtained a sigma level of 4.32. By using the six sigma method, at the measure stage in this study it was concluded that there were 6 causes of defects namely, waves, spotting products, pressure tests, product flashes, failed sockets, broken pipes. In calculating the sigma value, a sigma level of 4.32 is obtained. The factors that cause defects are known, namely human factors, machines, materials, and methods.
