Heavy Equipment Industry is a company operating in the mining heavy equipment industry. The Quality Control Department continues to strive to maintain and improve the quality of every product produced. During 2022 there were complaints from customers, where there were 7 complaints about hangers detaching from the frame. The hanger is a connecting component between the leaf spring and the chassis which functions as a support for the load. This has a very fatal impact because it is related to safety, unit function and unit productivity. The crack defect caused a repair process by re-welding the part of the hanger where the crack was present. The aim of this research is to reduce the defect rate in Hanger defects. The method used is DMAIC. Primary data and supporting data were collected through field observations to describe actual conditions before repairs. Based on the results of the analysis and improvements that have been carried out, it was found that creating work instructions for the process of attaching hangers to units can help manpower understand the process and work sequence in hanger fabrication. The proposal to add reinforcement check points to the hanger setting check sheet is hoped to be able to maintain the hanger without reinforcement entering the next process and increase supervision of the hanger welding quality.

“…Trimarjoko [49] reduces defects in tire products by increasing the sigma level from 4.48 to 5.02. Maryani [50] process capability improvement in aluminium alloy wheel casting with product performance results from Cp = 0.81 to Cp = 1.4 and an increased level of sigma level = 2.9 to sigma level = 4.0. Setiawan [51] reduces defects in roof panel products in the quality of the packaging process with improvements that can reduce the DPMO value from 33,500 units to 2,050 units and increase the sigma level from 3.33σ to 4.37σ.…”

The main purpose of this white paper is to analyze current research on Six Sigma in the auto parts industry and identify opportunities for further research. This study used a systematic literature search of the most recent scientific articles (2013-2022) searched using specific inclusion and exclusion criteria. His two main categories of research goals emerged. The development of Six Sigma and the impact of Six Sigma. In recent years, research on the impact of Six Sigma is the most popular and has always been there from year to year, while research on the development of Six Sigma is the least popular. The study can provide insights to researchers, consultants and quality managers in developing and implementing Six Sigma in the automotive components industry sector. This research found that there is a lot of research on the complete Six Sigma methodology in the automotive component industry, especially research on the impact of implementing Six Sigma. From these findings, the main avenue for future research can be identified, namely Six Sigma Digitalization.
