Abstract

Intense competition in the beauty clinic industry requires consistent service quality improvement because customer satisfaction determines loyalty and business sustainability. Service marketing literature confirms that perceived service quality can be measured through ServQual; however, studies integrating ServQual, Importance Performance Analysis (IPA), and Customer Satisfaction Index (CSI) in beauty clinic settings remain limited. This gap motivates the present study to analyze priority service attributes at Larissa Aesthetic Center Darmo. The objectives are to evaluate service quality, identify improvement priorities, and measure customer satisfaction levels. The study employed a quantitative approach with correlational, comparative, and associative designs involving 85 respondents selected through purposive sampling. Data were collected using Likert-scale questionnaires that met validity and reliability standards. The findings reveal a service conformity level of 93.96%, although several ServQual dimensions still showed negative gaps. IPA positioned facility comfort and staff professionalism in the main priority quadrant, while a CSI score of 85.09% indicated very high customer satisfaction. The main insight suggests that high overall satisfaction does not eliminate specific service weaknesses. This study contributes practical data-driven guidance for clinic management, while its originality lies in integrating three measurement tools within the beauty clinic context.

Abstract

This study examines the integration of structural performance analysis and occupational accident risk assessment in a multi-storey building project using a quantitative approach based on nonlinear pushover analysis and FMEA. Structural evaluation is commonly conducted separately from safety risk analysis, resulting in non-integrated technical decision-making and risk control. This study aims to identify the seismic performance of the structure and determine accident risk priorities based on the Risk Priority Number (RPN). Nonlinear pushover analysis was performed using ETABS to obtain drift and base shear values; risk evaluation applied FMEA (Severity, Occurrence, Detection); and root causes were analyzed using a Fishbone Diagram. The maximum drift reached 216.317 mm with a base shear of 45,737.96 kN (Infilled Frame, Y-direction) and 206.337 mm with 10,199.32 kN (Open Frame, Y-direction). The highest risk occurred in foundation work with an RPN of 174,857.14. Strengthening lower-storey stiffness and implementing performance-based high-priority risk control are required. This research proposes an integrated evaluation model linking structural response and construction safety risk management quantitatively and systematically.

Abstract

The increasingly competitive footwear MSME business environment requires business owners to improve service quality while maintaining customer satisfaction and loyalty. However, many MSMEs still face challenges related to response speed, service consistency, and personal communication. This study aims to analyze the service quality of footwear MSMEs in Bungah District using the SERVQUAL, Value Engineering, and TOPSIS approaches to determine priority strategies for service improvement. The study employed a quantitative method involving 70 customers of footwear MSMEs. The results showed that the average SERVQUAL gap was −0.75, indicating that service quality had not yet met customer expectations. The responsiveness dimension became the most critical aspect with a gap value of −1.25, followed by empathy at −1.00, while reliability had a gap of −0.60. These findings indicate that customers highly demand fast, responsive, and personalized services. Based on value engineering analysis, the service functions that contributed most significantly to quality improvement were rapid response, service accuracy, and customer communication. Furthermore, the TOPSIS method identified WhatsApp Business implementation as the top priority strategy for improving response speed, with a preference value of 0.78, followed by production and delivery scheduling with a value of 0.72. This study contributes to the development of MSME service quality improvement strategies that are more systematic, measurable, and customer-oriented.

Abstract

Wheelsets are vital components in railway systems that function to support loads, maintain stability, and transmit motion forces during operation. However, the high level of wheelset defects during the overhaul process indicates the need for a more effective and sustainable quality control system. This study aims to analyze the dominant defect types and formulate improvement strategies for wheelset quality at PT XYZ using the Seven Tools method and SWOT analysis. The research methodology was conducted through the collection of wheelset inspection data from January to December 2024, which were then analyzed using check sheets, histograms, Pareto diagrams, control charts, scatter diagrams, and fishbone diagrams. The results showed that wheel wear was the dominant defect at 61%, followed by cracks at 20% and flat spots at 19%. These findings indicate that operational factors, machine maintenance, and SOP implementation are the main causes of defects. Improvement strategies focused on enhancing technician training, optimizing maintenance activities, and strengthening operational supervision. This study contributes to the development of a more systematic wheelset quality control approach to support railway operational reliability and safety.
