Abstract

Product and service quality factors are important aspects of business continuity. Consumers will abandon low-quality products and services. Consumers will feel satisfied if all aspects of the products and services are appropriately accommodated. Product and service quality have different tendencies because service quality dimensions are more complex than product quality. This study aims to analyze the quality of customer service at auto repair shops based on consumer preferences. Assessment of the level of satisfaction and consumer expectations of each attribute is done by filling out a questionnaire to identify the gap between the level of importance and level of performance. The consumer's assessment of each indicator of the auto repair shop is carried out through a questionnaire filled out to the consumer to find out the gap between the level of importance and the level of performance. The analytical method used is Importance Performance Analysis–IPA showing that the attributes of auto repair shops that need to be improved are [P1] improving the repair period as promised, [P2] Procedures and managerial capabilities in providing adequate service, [P3] Results following consumer recommendations, and [P4] Knowledgeable workshop managers and staff, [P5] Service speed from responsiveness quality dimensions, [P11] Credibility and honesty of workshop managers and staff, [P12] Clarity of communication and information to consumers. The priority of quality attributes of auto repair shops that will be improved can provide alternative development priorities between human resources and limited equipment servicing.

Abstract

The research aim to reduce the potential for product defects in the automotive component industry by implementing Plan-Do-Check-Action (PDCA). The application of the PDCA method was carried out in an automotive component manufacturing company in Indonesia which produced SLJ 91 parts as a research object. The causes of the high number of product defects are known at the Plan stage from setting the theme of improvement to the root cause by using a fishbone diagram and 5W+1H analysis. In the Do stage, system improvements are implemented from the solutions generated by the 5W+1H analysis. The repair results are controlled to confirm the results of the repairs made. The corrective actions taken resulted in a reduction in product defects of 2.8% so that they were included in the maximum tolerance for the number of defects in the SLJ 91 part. Based on the results of data processing, analysis, and comparison between before and after implementation, it was found that the defect rate for SLJ 91 products was reduced from 10.8 % to 8%, a reduction in the percentage of 2.8% so that the product reaches the quality target it should be. The results of the repair had a direct impact on the type of dent defects, namely a decrease in the number of defects from 8.6% to 5.3%, so that there was a decrease of 3.3%. The results of the research are implemented and standardized in the action stage so that the improvements made can be maintained in the long term.

Abstract

This study aims to reduce the failure of the measurement process on Part Reinf BK6 in the automotive industry which prioritizes accuracy and precision in the process to maintain product quality and customer satisfaction. This study used the measurement system analysis (MSA) method to analyze the Gage R&R on a measurement system, with 2 operators and 10 parts measured with 3 repetitions. The MSA results before improvement showed a Total Gage R&R of 67.80% with a repeatability value of 0.98% and a reproducibility value of 66.82%. The result indicated that the measurement system needs to be improved because the Gage R&R is still above 30%. After improving the measurement process by adding the Go No Go pin as an additional tool, the MSA results show the Total Gage R&R value after the improvement is made to 10.11% with repeatability and reproducibility values of 10.11% and 0% respectively. Based on the results of the study, it can be concluded that the improvements made have a significant effect on the measurement system on Part Reinf BK6. This will improve accuracy and precision in the measurement process, maintain product quality, and increase customer satisfaction. Therefore, improving the measurement system is very important in the automotive industry.

Abstract

PT HMG is an injection molding company that is a subcontractor of PT Ichikoh Indonesia. The variety of product types produced and the irregular placement of products belonging to subcontractors PT Ichikoh Indonesia resulted in a buildup of products, which resulted in ineffectiveness in searching for goods and moving goods. This problem can result in longer handling times and longer handling distances. Based on these problems, PT HMG decided to add a storage area as a warehouse, which will function as a place to store products belonging to subcontractor PT Ichikoh Indonesia. So, it is necessary to design a layout so the products are neatly arranged and make it easier for warehouse operators to search and handle them using dedicated storage and class-based storage methods. The distance obtained using the dedicated storage method was 9,013 m, and the handling time was 180,277 minutes. Meanwhile, using the class-based storage method, the transfer distance was 10,180 m, and the handling time was 203,601 minutes. The selected warehouse layout design is a layout with a dedicated storage method.

Abstract

This research aims to improve project quality at PT ABC by integrating the Fuzzy Analytical Hierarchy Process (F-AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) within the Lean Six Sigma framework. This method assesses and selects quality improvement projects by considering uncertainty and complexity in decision-making. The Fuzzy AHP approach is used to flexibly assign criteria weights, while TOPSIS is used to rank projects based on performance scores relative to the ideal solution. This research aims to select the most suitable Lean Six Sigma project using the MCDM fuzzy AHP and TOPSIS approaches at PT ABC. There are three alternative quality improvement projects and three assessment criteria. The data processing results using Fuzzy AHP and TOPSIS showed that the most influential criterion was the impact criterion, with a value of 0.665. Overall, the order of influencing criteria is cost (0.260) and time (0.075). Based on a review of all criteria, the project to increase the drive plate production line (A) capacity was ranked first with a value of 0.772. Second place is the project to increase capacity and consolidate rear axle assemblies A and B with a value of 0.5529. Finally, the third is the process innovation and integrated manufacturing project to strengthen the business with a value of 0.4053.

Abstract

Vehicle type approval (VTA) total registration of electronic vehicles in Indonesia for the accumulation period until August 2023 is 81,525 units with a composition of 4-wheeled vehicles 18,300 units. The use of electric vehicles is still a tiny portion compared to the motorized vehicle population in Indonesia, which will reach more than 146 million units in 2022. It is different from developments in Europe, the United States, and China, where more research into the use of electric vehicles is being carried out. The readiness of the automotive industry system to produce electric vehicles is absolutely necessary to achieve superior productivity levels. National auto­motive companies need to anticipate that changes in production systems will also change along with changes in processes and components in electric vehicles. In the next few years, world-class manufacturing production systems will refer to LARG (lean, agile, resilient, and green) aspects. Lean, agile, resilient, and environmentally friendly manufacturing industrial opera­tions are critical. This research aims to determine the level of appli­cation of LARG aspects in the electric vehicle automotive industry. The method used was exploratory, and a questionnaire was filled out with industry experts and analyzed using the analytical hierarchy process (AHP) and objective matrix (OMAX). The results of this study confirm that all aspects of LARG require improvement. Resilience (R) and green (G) have performance below 10 percent, so these two aspects are priorities for improvement by the electric car industry in Indonesia.
