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

Higher education has great demands and responsibilities to ensure their student graduates as highly competent human resources. Thus, effective and efficient management is required for higher education’s business process. To ensure their quality in process and result, compliance with national regulations and standards related to higher education is a must, and quality conformity with international standards is also one of the efforts of higher education institutions to improve their quality and competitiveness. ISO 21001:2018 is one of the international standards and best practice management systems for educational organizations that are widely used by various higher education institutions in the world. Considering Politeknik STMI Jakarta’s vision for resulting competent human resources, and that it is not yet certified by ISO 21001: 2018, this study is conducted to know the extent of readiness of Politeknik STMI Jakarta  towards implementation and certification of ISO 21001:2018. The method used is the gap analysis method between conditions existing in Politeknik STMI Jakarta to ISO 21001:2018 standard. The results showed that the level of readiness of Politeknik STMI Jakarta is 88.85% which showed that the implementation of the clause requirements is mostly carried out but not consistently. The conclusion that can be drawn from the research is that Politeknik STMI Jakarta is ready to implement and carry out ISO 21001: 2018 certification.

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

The cause of global warming occurring in the world originates from the transportation sector, particularly Internal Combustion Engine (ICE) vehicles using fossil fuels. As a response, the Indonesian government has enacted regulations aimed at accelerating the adoption of electric vehicles. Electric vehicles developed in Indonesia encompass two-wheeled, three-wheeled, four-wheeled, and other types that operate by utilizing electrical energy stored in the vehicle's battery. One notable development involves the conversion of ICE motorcycles into electric motorcycles. This study seeks to assess the investment feasibility of implementing convertible motorcycles from economic, environmental, and social perspectives. The economic aspects are evaluated by calculating net present value (NPV) and payback period (PP), with the study's results demonstrating the economic viability of implementing convertible motorcycles. Furthermore, environmental considerations involve the comparison of chemical substances emitted as pollutants, with the results indicating the feasibility of this approach due to its potential to reduce air pollution. Lastly, the social aspect encompasses the review of potential impacts should converted electric motorcycles be produced on a large scale. The success of implementing convertible motorcycles necessitates the collaboration of various stakeholders, including the government, small and medium enterprises, electricity service providers, and the awareness of the public.
