Introduction

The Bunut shoe industry in Kisaran Barat District has been a prominent player in the shoe production industry for several years. In 2017, the company applied the Statistical Quality Control (SQC) method to ensure the quality of the shoe products produced. This study aims to analyze the implementation of quality control in the Bunut shoe industry using the X-Chart control diagram. The results of this study will provide valuable insights into the effectiveness of quality control in the company and its ability to meet market expectations.

Background of Statistical Quality Control (SQC)

Statistical Quality Control (SQC) is a statistical approach that functions to monitor and control the production process. By using a control diagram such as X-Chart, R-Chart, and S-Chart, companies can visualize data and identify whether the production process is within the specified control limit. The SQC method is widely used in various industries, including manufacturing, healthcare, and finance, to ensure the quality of products and services.

Methodology

This study used a case study approach to analyze the implementation of quality control in the Bunut shoe industry. The data collected from the company's production process was used to create an X-Chart control diagram. The X-Chart control diagram is a type of control chart that is used to monitor the mean of a process over time. The chart consists of three main components: the center line, the upper control limit (BKA), and the lower control limit (BKB).

Results

The results of this study show that all data points in the control diagram are within the set control limits, namely the upper control limit (BKA) and the lower control limit (BKB). This indicates that the shoe production process in the Bunut industry is in a statistical controlled condition. The results also show that the level of damage to shoe products can be controlled, thus creating higher quality products and meets market expectations.

Discussion

The importance of quality control does not only focus on reducing the level of product damage, but also on production efficiency and customer satisfaction. In the analysis conducted, it is proven that the level of damage to shoe products can be controlled, thus creating higher quality products and meets market expectations. In addition, good quality control can increase the company's reputation in the eyes of consumers and open up opportunities for greater business growth.

Conclusion

The conclusion of this study shows that the implementation of quality control in the Bunut Shoes Industry is at a good level and in accordance with the established standards. This reflects the company's commitment to product quality and its ability to adapt modern quality control techniques. For further development, companies are advised to continue to implement quality control and conduct routine evaluations to maintain product quality, so that they can compete in increasingly competitive markets.

Recommendations

Based on the results of this study, the following recommendations are made:

  • The company should continue to implement quality control and conduct routine evaluations to maintain product quality.
  • The company should invest in training and development programs for employees to improve their knowledge and skills in quality control.
  • The company should establish a quality control team to oversee the implementation of quality control and ensure that it is in accordance with the established standards.

Limitations of the Study

This study has several limitations. Firstly, the study only analyzed the implementation of quality control in the Bunut shoe industry and did not compare it with other companies in the industry. Secondly, the study only used a case study approach and did not use other research methods such as surveys or experiments. Finally, the study only analyzed the implementation of quality control in the Bunut shoe industry and did not analyze other aspects of the company's operations.

Future Research Directions

Future research should focus on comparing the implementation of quality control in the Bunut shoe industry with other companies in the industry. Additionally, future research should use other research methods such as surveys or experiments to gather more data and provide a more comprehensive understanding of the implementation of quality control in the company. Finally, future research should analyze other aspects of the company's operations, such as production efficiency and customer satisfaction.

Conclusion

In conclusion, this study provides valuable insights into the implementation of quality control in the Bunut shoe industry using the X-Chart control diagram. The results of this study show that the implementation of quality control in the company is at a good level and in accordance with the established standards. The study also provides recommendations for further development and future research directions.
