Abstract

The utilization of e-money in Indonesia has surged, propelled by the expansion of digital payment platforms. Despite their growing prevalence, the dynamics of e-money acceptance within urban environments remain underexplored. This study innovatively extends the Technology Acceptance Model (TAM) by incorporating Perceived Security as a new variable, alongside traditional factors such as Perceived Usefulness, Perceived Ease of Use, Attitude Toward Using, Behavioral Intention to Use, and Facilitating Condition. The research focuses on Padang City, a representative urban landscape, where data was collected from 201 valid respondents through online platforms. Data analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM). The integration of Perceived Security is a novel aspect of this study, reflecting its crucial role in the contemporary urban context of e-money utilization. Results reveal significant relationships among the studied variables, although the impacts of Facilitating Condition on Perceived Ease of Use and Perceived Usefulness on Behavioral Intention to Use were not supported. The findings underscore that positive attitude toward e-money significantly boost behavioral intentions to use it, primarily influenced by security perceptions and ease of use. These insights have substantial implications for policymakers and businesses focused on enhancing e-money adoption in urban settings. The study highlights the necessity of addressing user perceptions, particularly security, to foster broader acceptance. The limited influence of Facilitating Conditions suggests that improvements in infrastructure must be coupled with efforts to enhance user trust and ease of interaction with e-money platforms. This research contributes to the field by providing a deeper understanding of the factors driving e-money acceptance in urban areas, guiding targeted strategies for digital financial inclusion.

Abstract

This study reports the development of a web-based Point of Sale (POS) system for Café Sonia, an MSME café setting where day-to-day transaction handling and reporting benefit from a workflow-aligned digital solution. The system was produced using Rapid Application Development (RAD) through short, stakeholder-driven iteration cycles with explicitly bounded scope and systematic feedback incorporation, resulting in an end-to-end POS flow from ordering to receipt and transaction history. Performance metrics reported in this paper are derived from a small-scale JMeter run and should be interpreted as an indicative baseline rather than evidence of peak-hour robustness. No dedicated usability evaluation was conducted; therefore, user-facing quality remains a pending empirical question that warrants task-based usability testing and standardized instruments such as the System Usability Scale (SUS) in subsequent iterations. Debates around RAD often hinge on a perceived tension between development speed and methodological accountability, particularly when systems must remain maintainable beyond the prototype stage. The Café Sonia case suggests that RAD can still yield a coherent, maintainable, and context-fit POS when iteration cycles are guided by stakeholders and the scope is clearly controlled. The novelty lies in providing case-based evidence of RAD’s practical effectiveness for delivering a customized MSME café POS, while the contribution is a traceable development pathway linking requirements capture, iterative prototyping artefacts, and scenario-based functional verification for reuse in comparable small-retail environments.

Abstract

This research compares the service quality of travel agent applications, which are KAI Access and Traveloka, in booking train tickets using the E-Service Quality and Importance Performance Analysis (IPA) methods. This service quality is measured based on seven dimensions of E-Service Quality, including efficiency, fulfillment, reliability, privacy, responsiveness, compensation, and contact. Data were collected through questionnaires from 340 respondents who use the KAI Access and Traveloka applications to book train tickets. The collected data were then analyzed descriptively using the Importance Performance Analysis (IPA) technique to identify priority attributes for improvement based on user satisfaction and importance levels. Based on the Gap Analysis and evaluation of 340 respondents, both the KAI Access and Traveloka apps require improvements as they still need to meet user expectations. The service quality of KAI Access and Traveloka shows significant differences across various dimensions measured by the E-Servqual and Importance Performance Analysis (IPA) methods. The research results are expected to provide recommendations for both applications to improve service quality and user satisfaction. The comparison of service quality is also expected to provide insights into the strengths and weaknesses of each application in providing train ticket booking services.

Abstract

Social media applications that continue to grow in society have made many companies innovate new social media applications. Behind this, application developers must know the factors that make their applications popular in order to maintain long-term use. This research aims to measure user intentions in using new social media applications as well as exploring and investigating potential factors that influence users in using new social media applications. The research method used is a quantitative approach by proposing a Technology Acceptance Model (TAM) with Innovation Diffusion Theory (IDT). Data collected was 424 respondents who had used new social media applications. From the results of the analysis of factors that influence users to want to use new social media applications namely Complexity, Observability, Perceived Compatibility , Perceived Enjoyment, Relative Advantage and Perceived Ease of Use. Apart from that, there is the influence of Observability, Perceived Compatibility, Perceived Enjoyment, Trialability, Perceived Usefulness, and the influence of Perceived Usefulness on Behavioral Intention to Use. From the results of this research analysis, it is known that the approach in the TAM and IDT models provides support that there are factors that influence users to use new social media applications. This research suggests further expanding the variables in TAM and IDT to find out more about the factors that influence users to use new social media applications, as well as looking for more indicators from the variables in this study to strengthen the validity and reliability of the research variables.

Abstract

This study aims to develop effective policies and strategies to promote the adoption of IoT technologies, particularly smart home usage in Indonesia, in light of the rapid increase in internet usage and to address the digital divide due to varying education and income levels. Utilizing the Technology Acceptance Model (TAM) and a quantitative methodology, the survey was conducted with 427 smart home users via a digital form distributed on social media. Data was analyzed using TAM variables and additional variables like privacy, compatibility, perceived ease of use, perceived usefulness, attitude towards using, behavioral intention to use, and actual system use, with demographics (income and education) as moderating variables. The results show that privacy, perceived ease of use, and perceived usefulness significantly influence attitudes towards using smart homes, which in turn positively affects users' intention to use them, while compatibility does not. Education and income levels weaken the relationship between external factors and intention to use smart homes. This research highlights the impact of demographic factors on IoT adoption and provides insights for technology providers and policymakers to enhance smart home device adoption in Indonesia.
