Abstract

Competition in the smartphone industry is increasingly intense, especially in the entry-level segment targeting lower to middle-class consumers. Xiaomi has become one of the favored brands because it can offer high specifications at affordable prices. This raises the question of how much product quality and price perception influence purchasing decisions, particularly in Bandung City. This study aims to analyze the influence of brand image and product quality on Xiaomi smartphone purchasing decisions, both partially and simultaneously. Using a quantitative approach, data were collected through questionnaires from 100 Xiaomi phone users in Bandung City selected through purposive sampling. This study is expected to provide input for business actors and marketers in designing effective strategies. The data processing was carried out using SPSS version 27 software with methods including validity test, reliability test, normality test, multiple linear regression, t-test, F-test, and coefficient of determination. The results show that product quality and price perception have a significant effect on purchasing decisions, both individually and simultaneously. The coefficient of determination value reaches 62.5%, which means that these two variables explain most of the variation in consumer purchasing decisions. The conclusion of this study is that Brand Image has a significant effect on purchase decisions. The t-test results show that product quality has a significance value of 0.000 (p < 0.05) and a regression coefficient of 0.497. Product quality has a positive effect on purchase decisions, showing a significance value of 0.000 (p < 0.05) and a regression coefficient of 0.574. Brand image and product quality simultaneously have a significant effect on purchase decisions. The F-test results show a significance value of 0.000 (p < 0.05), indicating that both variables together have an effect on purchasing decisions. The coefficient of determination (R Square) value of 0.625 shows that 62.5% of the variation in purchasing decisions can be explained by product quality and price perception. The remaining 37.5% is explained by other variables not examined in this study.

Abstract

The utilization of information technology (IT) in hospitals plays a strategic role in improving healthcare service quality, operational efficiency, and managerial decision-making. Along with the increasing dependence on information systems, effective IT governance is required to ensure alignment with organizational objectives and proper risk management. This study aims to measure the maturity level of information system governance at dr. Slamet General Hospital, Garut, using the COBIT 4.1 framework. This research employs a descriptive quantitative approach. Data were collected through observations, interviews, documentation studies, and questionnaires developed based on the COBIT 4.1 domains and processes, namely Plan and Organise (PO), Acquire and Implement (AI), Deliver and Support (DS), and Monitor and Evaluate (ME). The results indicate that the overall maturity level of information system governance at dr. Slamet General Hospital is 2.59, which corresponds to Level 2 (Repeatable but Intuitive). The Deliver and Support (DS) domain achieved the highest maturity level, while the Monitor and Evaluate (ME) domain showed the lowest level. These findings reveal a gap between the current condition of IT governance and the expected maturity level. Therefore, continuous improvement in information system governance is necessary through the establishment of formal policies, process standardization, and the implementation of regular monitoring and evaluation mechanisms to effectively support the hospital’s strategic objectives.
