ANALYSIS OF SIX SIGMA IMPLEMENTATION TO REDUCE FERTILIZER DEFECTS AT PT. PETROKOPINDO CIPTA SELARAS

Abstract

This study aims to analyze the application of the Six Sigma method in reducing defects in fertilizer bags at PT. Petrokopindo Cipta Selaras. The method used is a descriptive qualitative approach, with data analysis through interviews, observations, and analysis of defect data in production. The results of the study showed various types of defects, such as torn bags, imperfect stitching, and bag weight discrepancies. Measurements showed an average DPMO of 6,631.61 with a sigma value of 3.98, which is still below the Six Sigma standard, negatively impacting production efficiency and the company's reputation. Through the DMAIC (Define, Measure, Analyze, Improve, Control) stages, the causes of defects were found to include human, machine, raw material, method, and environmental aspects. Implementation of proposed improvements includes the addition of production supervisors, crushing and drying machines, periodic sewing needle changes, SOP enforcement with daily inspections, and improving the cleanliness of the work environment. It is hoped that these steps can reduce the defect rate and improve product quality. With the implementation of Six Sigma, the company is expected to achieve better operational efficiency and increase customer satisfaction.
