Abstract

The integration of technology into education has garnered significant interest, particularly for its potential to support environmental sustainability. Urban bus and bus rapid transit (BRT) systems must deliver passenger-centered service quality that is both measurable for operators and meaningful to users. However, service-quality research often relies on generic perceptual scales that are difficult to translate into actionable operational interventions. This study advances an engineering-oriented Stimulus–Organism–Response (S–O–R) framework by conceptualizing Transit Engineering Quality of Service (TE-QoS) as an actionable stimulus and examining its relationships with perceived value, satisfaction, and behavioral intention in the context of urban bus services in Indonesia. Data were collected through an offline intercept survey of Trans Jatim passengers in the Surabaya metropolitan area between June and July 2024, yielding 300 valid responses for analysis. Using CB-SEM (AMOS), the measurement model demonstrated satisfactory reliability and validity. The structural results indicate that perceived value strongly predicts satisfaction (β = 0.698, p < 0.001), whereas TE-QoS exerts a positive, though comparatively modest, direct effect on satisfaction (β = 0.122, p = 0.017). Satisfaction, in turn, strongly predicts behavioral intention (β = 0.700, p < 0.001). The Model explains 50.2% of the variance in satisfaction and 48.9% of the variance in behavioral intention. These findings suggest that operational improvements in reliability, regularity, travel-time efficiency, access, comfort, information, and safety are more likely to strengthen loyalty-related intentions when passengers perceive them as clear gains in value. Future research should integrate objective operational data and formally examine indirect mediation pathways.

Abstract

Mobile banking has become a primary channel for retail financial services in emerging economies; however, prior research has focused predominantly on initial adoption intention rather than post-adoption usage behavior. This study addresses that gap by integrating the Technology Acceptance Model and the DeLone and McLean IS Success Model to explain post-adoption mobile banking usage in Indonesia. A quantitative cross-sectional survey was conducted with 544 active users of mobile banking applications from four Indonesian state-owned banks, and the data were analyzed using PLS-SEM. The results indicate that perceived ease of use significantly enhances perceived usefulness (β = 0.549, t = 14.213, p < 0.001). In turn, perceived usefulness (β = 0.192, p < 0.001), system quality (β = 0.247, p < 0.001), information quality (β = 0.225, p = 0.001), and service quality (β = 0.195, p < 0.001) positively affect user satisfaction. User satisfaction, in turn, emerges as the strongest direct predictor of self-reported actual usage (β = 0.523, t = 12.044, p < 0.001). The model explains 30.2% of the variance in perceived usefulness, 51.2% of the variance in user satisfaction, and 27.3% of the variance in actual usage. These findings indicate that post-adoption mobile banking usage is shaped not only by cognitive acceptance beliefs but also by users’ evaluations of system performance, information quality, and service support. This study contributes to post-adoption digital banking research by demonstrating that satisfaction is the central evaluative mechanism linking acceptance beliefs and service-quality perceptions to sustained behavioral usage.

Abstract

Passive flow control of circular-cylinder wakes remains important because wake organizations govern aerodynamic loading, force fluctuations, and vortex-induced response. This study examines how vortex-generator (VG) planform and height affect lift behavior and near-wake structure around a circular cylinder. Triangular and ogival VGs with heights of 4, 7, and 10 mm were mounted at the cylinder apex and evaluated using three-dimensional transient URANS simulations with the SST k–ω model at Re = 53,000. Supporting wind-tunnel force measurements were also performed to assess whether the numerical trends were qualitatively reproduced experimentally. All VG-equipped configurations reduced the recirculation region, narrowed the wake, and decreased the centerline velocity deficit relative to the clean cylinder. Among the triangular cases, the 10 mm VG produced the strongest wake contraction, reducing the recirculation length from 1.35D to 0.70D. Among the ogival cases, the 10 mm VG generated the highest peak lift coefficient (approximately 1.45), although its wake contraction remained slightly weaker than that of the corresponding triangular configuration. These results show that the geometry yielding the strongest wake suppression is not identical to that giving the highest lift enhancement. The wind-tunnel measurements reproduced the overall ranking trends. However, because the experimental inflow conditions were not Reynolds-number matched to the numerical setup, the comparison is interpreted as qualitative trend support rather than strict validation. The results demonstrate that the VG planform and height jointly control the trade-off between wake contraction and lift enhancement.
