“…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. Supriyati [52] reduces paint defects on automotive parts with a DPMO value of 7619 and a Sigma value of 3.9. Armandhika Utomo [53] decreased flow-out defects and ratio defects in comp jack bracket parts with sigma values from 3.3 to 4.0.…”

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.

“…One of the methods that complement the RCA process is FTA [7], [8], which is frequently used for reliability analysis in critical systems [9], [10], and [11]. Other approaches that can be used to prevent product damage due to system or process failures before the problem occurs can be made through FMEA [12], [13] to improve the quality and analysis of product inconsistency [14]. FMEA is a bottom-up method that is less structured and requires more expert knowledge than FTA, which is a top-down method [15], and this tool has become one of the most commonly used in industries [16], [17].…”

One of the company's efforts in implementing the commitment to customer satisfaction is carried out through continuous improvement activities. All indicators are evaluated to determine the level of quality stability against process variations that will impact non-compliance with predetermined product specifications. One of the quality problems found in the tire manufacture industry is the out-percentage of tire uniformity, which suddenly increases, one of which is the value of static balance. This study analyses the process variation factors that occur to take corrective and preventive actions through a series of Root Cause Analysis (RCA), Fault Tree Analysis (FTA), and Failure Mode and Effect Analysis (FMEA). Refers to the analysis result, it was found that there was a problem with the rubber film gauge variation at the manufacturing step of the steel breaker, one of the material components in the tire construction. Two main factors cause rubber film thickness variation: rubber sticky with roll calendar, Radial Run Out (RRO) Roll Calendar out standard, and viscosity compound variation with 12 root problems found. The results of the improvements that have been made can effectively improve rubber film thickness variation, increase the Cpk level of steel breaker material from 0.82 to 1.91 and reduce the out percentage ratio of static balance by 54.65%.

“…In general, if these specifications are not met, the product is considered non-compliant and defective [1]. Quality improvement can affect the success of a business [2]. The ability of the process to produce products that meet the specifications if the process has good capabilities, then the process will produce products that are within the specification limits between the lower and upper specification limits [3].…”

The global market demand for automotive wheels with alloy materials is 55%, which is quite high compared to other materials such as steel, magnesium, chromed, and carbon fiber. The high competition of the global alloy wheels market demands to be able to offer quality alloy wheels. The purpose of this research is to reduce the number of defects in the casting process step by using the Define Measure Analyze Improve Control (DMAIC) method. This study shows the systematic approach to find the root cause of major defects in aluminum castings using the defect diagnostic approach as well as cause and effect diagram. Quality improvement using quality tools, namely the Pareto diagram, fishbone diagram. The major defects for the rejections during production were identified as leak defects, porosity motive holes, and oval defects. In determining the proposed quality improvements using the FMEA tool. The results of data processing on the calculation of process capabilities and product performance show improvements after quality improvements in the casting process. Product performance from DPMO = 15.462, sigma level = 3.6 to DPMO = 8.186 and sigma level = 3.9. The effect of decreasing the percentage of defects could save production costs by IDR 413.350.000. Therefore, the application of the DMAIC method can provide a significant improvement in product quality and impact on production cost savings.
