Analisis Pengendalian Kualitas Produk Wiring Harness Pada Line 4 Menggunakan Metode PDCA Di TF STT Texmaco

Abstract

PT Piranti Indonesia is a manufacturing company that produces wiring harness. Based on observations, it is known that defective products or defects are often found in the housing process during October - December 2022. Therefore, this study aims to find out the causes of defects in the housing process, find out efforts to minimize the occurrence of defects in the housing process to improve quality, and make improvements to reduce defects in the housing process at least 10%. The quality control method used in this study uses the Plan-Do-Control-Action (PDCA) cycle assisted by tools such as histograms, Pareto charts, p control charts, cause-and-effect diagrams, and Failure Mode Effect Analysis (FMEA) which are implemented in Teaching Factory STT Texmaco Subang. The results of this study indicate that the most defective products are caused by terminals push out due to the human factor or the operator does not understand the applicable Standard Operating Procedure (SOP). After carrying out improvements by conducting refresh training, it was found that the defects that occurred during January - March 2023 were only 15% from the previous 29% in the period October - December 2022. This shows that the use of the PDCA cycle can minimize defects resulting in a decrease in defects caused by the Terminal Push Out by 14%.
