Public transportation plays an important role in supporting community mobility and accelerating regional economic growth. To improve public transportation services in East Java, the East Java Provincial Transportation Agency introduced the Trans Jatim Bus system. However, its implementation still faces several challenges, including long bus arrival times, the use of mobile applications that are difficult for elderly users, and inconsistencies in the availability of supporting facilities such as seating and trash bins at bus stops. This study aims to analyze the quality of Trans Jatim Bus services based on the service quality dimensions proposed by Wirtz and Lovelock. The research employs a descriptive qualitative approach. Data were collected through interviews, observations, and documentation, and analyzed using stages of data collection, data reduction, data presentation, and conclusion drawing. The findings indicate that reliability has not met service standards due to prolonged waiting times. Responsiveness and assurance were found to meet service standards, as passengers expressed satisfaction with service responses and complaint handling. Empathy was considered adequate, although accessibility issues for elderly passengers remain. Tangible aspects were also sufficiently met, but inconsistencies were found in the provision of seating and trash bins at several bus stops. Based on these findings, the study recommends increasing the number of buses on corridor 2, evaluating bus schedules, conducting public awareness campaigns, and ensuring the consistent provision of seating and trash bins at all bus stops to improve overall service quality.

This study aims to analyze the factors that affect passenger satisfaction at the airport through three main perspectives, namely: service, technology, and operations. The approach used is a literature study of ten scientific journals that discuss airport service quality from various aspects. The results of the study show that service quality, especially those covering SERVQUAL dimensions such as reliability, responsiveness, empathy, assurance, and physical evidence, plays a major role in shaping service user perceptions. The technology perspective, through the implementation of self-service such as self check-in, Flight Information Display Sistem (FIDS), and digital service applications, is proven to increase efficiency and convenience, even contributing up to 96.8% to user satisfaction according to one study. Meanwhile, from an operational perspective, aspects such as queue time at check-in counters, public facilities, and accessibility to the terminal also have a significant impact on the overall passenger experience. The conclusion of this study emphasizes the importance of integration between the three perspectives in designing strategies to improve airport service quality. Suggestions are given to airport managers to continue to improve services, expand technology adoption, and reorganize operations to create a safe, comfortable, and satisfying travel experience for all service users

This study aims to analyze the factors influencing passenger satisfaction at airports through three main perspectives: service, technology, and operations. The background of this research is based on the increasing competition between airports in providing an optimal travel experience amidst the development of the aviation industry and the increasing passenger demands for service quality. This study uses a literature study approach by analyzing ten selected scientific journals that specifically discuss airport service quality from various perspectives. The results of the study indicate that the service perspective, specifically those encompassing SERVQUAL dimensions such as reliability, responsiveness, empathy, assurance, and tangibles, has a significant contribution in shaping the perception and satisfaction of airport service users. The technology perspective also plays a significant role, particularly through the implementation of self-services such as self-check-in, Flight Information Display Sistem (FIDS), e-gates, and digital service applications that simplify the travel process. One of the studies analyzed shows that the application of technology can contribute up to 96.8% to user satisfaction, indicating the significant role of digitalization in this industry. From the operational side, factors such as speed of service at the check-in counter, queue time management, completeness and cleanliness of public facilities, and ease of access to the terminal have an equally important influence. These findings underscore that passenger satisfaction is influenced not only by service quality at the point of direct interaction, but also by the smoothness of the overall operational flow. The study's conclusions emphasize the importance of integrating these three perspectives in strategic planning for airport service improvement.

This research investigates the impact of several key factors on customer satisfaction at the KAI Company, specifically for train services operating at Poncol Station in Semarang. Classified as causal research, the study focuses on identifying how variables such as electronic service quality (e-quality), complaint handling, station facilities, and punctuality contribute to improved satisfaction among passengers. The research population consists of all train users at the station, without a fixed number, while a sample of 100 respondents was selected using the Lemeshow formula. Data collection methods involved the use of structured questionnaires and interviews with passengers to gain both quantitative and qualitative insights. The data analysis revealed that 85% of customer satisfaction levels can be attributed to the four main factors mentioned: the quality of digital services, the effectiveness of complaint resolution, the availability and quality of facilities, and adherence to schedules. The remaining 15% of satisfaction is influenced by other, unexamined variables. Each of the four tested variables was found to have a statistically significant individual (partial) impact on customer satisfaction. Furthermore, the simultaneous (overall) testing confirmed that these factors collectively have a strong and meaningful effect on how passengers perceive the quality of the rail service. The findings emphasize the importance of consistently improving these specific operational areas to enhance customer experiences. In particular, maintaining service reliability, responding to customer complaints efficiently, improving digital interfaces, and upgrading station facilities can lead to greater satisfaction and potentially increase customer loyalty. The study suggests that service providers like KAI must adopt a customer-centered approach that focuses on both digital and physical aspects of the travel experience to remain competitive in the transportation industry.
