Statistical Quality Control and Failure Mode and Effect Analysis Methods to Reduce Packaged Defective Products at PT. Sinar Sosro

Introduction

In today's competitive market, maintaining good product quality is crucial to meet the desires and needs of consumers. As one of the leading companies that produce ready-to-drink tea in Indonesia, PT. Sinar Sosro is committed to maintaining the quality of its products. The company sets product quality standardization at 0.2%, but during the production process, PT. Sinar Sosro faces significant problems in the form of high levels of defects, which results in a decrease in quality. This study aims to identify the causes of defects and provide improvements to improve product quality using two methods: Statistical Quality Control (SQC) and Failure Mode and Effect Analysis (FMEA).

The Importance of Product Quality

Product quality is a critical aspect of any business, and it plays a significant role in determining the success of a company. Good product quality not only increases customer satisfaction but also helps companies maintain a competitive position in the market. In the case of PT. Sinar Sosro, maintaining product quality is essential to meet the expectations of consumers and remain competitive in the market. The company's commitment to product quality is reflected in its product quality standardization, which is set at 0.2%.

Product Defects and Their Causes

During the production process, PT. Sinar Sosro faces significant problems in the form of high levels of defects, which results in a decrease in quality. The study found several types of defects in bottled tea products, such as non-standard volumes, tilted cover, gupil bottles, and cracked bottles. These defects not only affect the quality of the product but also impact the company's reputation and customer satisfaction.

Product Defect Analysis

To identify the factors causing the emergence of defects, a causal diagram is used. This diagram helps in mapping various possible causes that contribute to the occurrence of problems, so companies can understand which aspects need to be improved. Furthermore, the analysis using Failure Mode and Effect Analysis (FMEA) is carried out to identify potential problems and determine the right preventive measures.

Failure Mode and Effect Analysis (FMEA)

FMEA is a method used to identify potential problems and determine the right preventive measures. The study found that the risk priority number (RPN) was 294, which shows the highest level of failure risk. This risk was identified from filler machines that did not work optimally. Thus, filler machines are a top priority in the improvement program.

Implications of Improvement

The application of the SQC and FMEA method gives a deep insight into the company's production process and areas that require more attention. With a focus on the improvement of filler machines, it is expected that product defects can be minimized, which in turn will improve the quality of the product as a whole. Better quality not only increases customer satisfaction but also helps PT. Sinar Sosro in maintaining a competitive position in an increasingly stringent market.

Benefits of SQC and FMEA

The use of SQC and FMEA methods has become increasingly crucial in the modern industrial world, where product quality is one of the keys to the company's success. By implementing these steps, PT. Sinar Sosro can be committed to maintaining product quality standardization and meeting consumer expectations. Well-maintained quality will contribute to the company's reputation and sustainable business growth.

Conclusion

Through a data-based approach and systematic analysis, PT. Sinar Sosro not only strives to reduce defective products but also invests in better future quality. This is an important step to ensure that the company continues to meet the needs of consumers and remain competing in the market. The study highlights the importance of SQC and FMEA methods in improving product quality and reducing defects. By implementing these methods, PT. Sinar Sosro can maintain its competitive position in the market and meet the expectations of consumers.

  3. Monitor Product Quality: It is essential to monitor product quality regularly to ensure that the quality of the product meets the expectations of consumers. Therefore, it is recommended that PT. Sinar Sosro monitors product quality regularly.

Limitations of the Study

The study has several limitations, including:

  1. Limited Data: The study is based on limited data, which may not be representative of the entire production process.
  2. Subjective Analysis: The study is based on subjective analysis, which may be influenced by personal biases.
  3. Limited Scope: The study has a limited scope, which may not cover all aspects of product quality.

Future Research Directions

The study highlights several areas for future research, including:

  1. Improving Filler Machines: Future research can focus on improving filler machines to minimize product defects.
  2. Implementing SQC and FMEA Methods: Future research can focus on implementing SQC and FMEA methods to improve product quality.
  3. Monitoring Product Quality: Future research can focus on monitoring product quality regularly to ensure that the quality of the product meets the expectations of consumers.

Conclusion

In conclusion, the study highlights the importance of SQC and FMEA methods in improving product quality and reducing defects. By implementing these methods, PT. Sinar Sosro can maintain its competitive position in the market and meet the expectations of consumers. The study provides several recommendations for improving product quality, including improving filler machines, implementing SQC and FMEA methods, and monitoring product quality regularly.
Frequently Asked Questions (FAQs) about Statistical Quality Control and Failure Mode and Effect Analysis Methods
