Quality Improvement of Filter Product by Reducing Defect Printing Peel-off Area Seam (Case Study) in the Automotive Components Filter Industry

Abstract

The development of the automotive industry in the world continues to grow, including also the development of the automotive industry in Indonesia, along with the development of the business, supporting industries that supply components for parts used for automotive must prepare it, especially in terms of quality, quantity, and accuracy of delivery. There are still several automotive failures in terms of quality that have caused recall, it’s as the reason why the research was conducted. Research carried out in one of the oil filter manufacturing industries where defect products namely peel off on the seaming area was reached 35.21%from the total amount of defects that occurred. The focus and purpose of the research are the effort to reduce printing defects. Several techniques are used in this research, such as work time measurement, line balancing approach, and some statistical tools for quality improvement, such as Pareto, fishbone diagrams, and why-why analysis. The result of the study was identified that the dominant cause of printing peel off on the seaming area was caused by the handling process on the packaging line when overlapping time. The handling process has been improved by reducing process handling with added transfer conveyors. Theeffectiveness of improvement has reported in March 2019 that the number of defect printing peels off the seaming area on oil filter products decreased by 46.74%
