PT Makmur Artha Sejahtera (PT MAS) is a company that produces various types of products such as jelly and fruit-flavored beverages. The quality of these products is always ensured to comply with Food and Beverage (FnB) regulations. However, during the period from March to December 2022, the products JellVit 70ml and Jelly Stick had the highest reject percentages in their respective production departments (cup & jelly), reaching 14.48% and 36.78%. These reject rates exceed the company's maximum target average of 5%. As a result, the production targets for these two products are often not achieved. Therefore, through this research, a quality improvement will be designed using the Six Sigma methodology with the DMAIC approach (Define, Measure, Analyze, Improve, and Control) to reduce the reject rate by lowering the proportion of defective products. In the define stage, the quality issues at PT MAS are explained, and a Six Sigma project is formulated by forming a Six Sigma team. Then, in the measure stage, the average sigma values for JellVit 70ml and Jelly Stick products (March-December 2022) were obtained, each at 2.328 and 2.846, based on process capability measurements. Moving on to the analyze stage, the Delphi method is used to determine the factors and sub- factors causing defects. These sub-factors causing defects will be assessed and ranked based on the RPN score using the FMEA method for improvement. The results of the analyze stage will be used as the basis for generating alternative improvement solutions in the improvement stage. In this stage, 3 alternative solutions for JellVit 70ml and 2 alternative solutions for Jelly Stick are proposed and approved. The proposals provide estimated improvement results related to the opportunity to reduce the defect percentage by 6.4% and 2.3% respectively. Finally, in the control stage, a schedule for implementing solutions is developed, and SOPs are created to ensure the proper implementation of the solutions.
