Abstract

The shoe industry faces many challenges in running its business, one of which is a decline in production. This is due to the continued high number of defective products produced by the existing process. This study focuses on the printing/screening division which has a high cost impact on production. This study aims to analyze the factors that cause product defects and provide suggestions for improvement efforts. The method used in this improvement is PDCA (Plan-Do-Check-Act). The PDCA approach is one method used to help improve production quality sustainably. The results of this study found that several factors causing defects were unstable/damaged heater lamp temperatures, no temperature checking standards, the use of chemicals that do not meet standards, dirty table mats and leaving residue on the glue. Based on several improvements that have been implemented, there has been a significant decrease in defective/defective product output from before. In the fourth week of April, the number of defective products was 379, a decrease compared to the previous week in the same month, which was 871 defective products.

Abstract

The quality of footwear products such as shoes is a major factor that influences the success of a company in producing footwear products. Shoe companies usually have various quality control methods to maintain the production process. One of the most widely used methods in the industry is the statistical quality control method. PT ABC is a company that produces sports shoes located in Bandung. ABC Company is experiencing problems in terms of production, namely the number of defective products produced is still high. This study aims to apply statistical quality control to control the number of defects that appear in the production process. The application process is focused on the problems that arise in the screen printing division where there are many defects that appear during the production process. The steps taken in this study include data preparation and initial analysis using check sheets and Pareto diagrams, data adequacy tests, making p control charts, and analyzing results. Based on the control chart that has been made on the initial defect proportion and the proportion of defective data after improvements have been made to the screen printing process, it can be concluded that there is a decrease in the average value of the defect proportion of 0.02. This figure is quite significant. In addition, there was a drastic decrease in the LCL (lower control limit) value. This significant decrease is a positive indication that the improvements made to the screen printing process have succeeded in reducing product defects significantly.
