Application of Pareto Analysis and Ishikawa Diagram on Bottling Industry: A Case Study Ambo Mineral Water Share Company

This research focuses on minimization of defects which causes for product packaging quality of control failure in AMWSC. The purpose of this research is to increase the quality and productivity improvement in the company by minimizing reworks that usually occur in the company product packaging process. Due to this qualitative method has been conducted to provide insights and understanding about the problems. Regarding to this important data was collected from PET production packaging line. In this process the identification of defects which causes failures for quality control product packaging has been conducted. Then, it was analyzed using Pareto Analysis and Ishikawa diagram. As the analysis made for 80/20 rule the production quality of PET on packaging section mostly affected defects by filler centering bell problem 11.3%, Labeler sensor fault 9.95%, Air filler leakage 8.4%, Air conveyor problem 7.79%, syrup ratio problem 7.34%, filler under fill and leakage 7.02%. Then, the root causes of PET product packaging process categorized by cause and effect diagram. Generally, based on the application of Pareto chart and Ishikawa diagram analysis the paper suggests how to handle these issues and minimize reworks or bring down defects rate.
