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

Innovation and technological progress have significantly impacted various sectors, notably Indonesia's financial and banking industry. This sector has seen remarkable growth, particularly with the rise of digitalization. A prominent development in this context is financial technology, or fintech, which has emerged to address needs and issues not sufficiently met by traditional banking services in Indonesia. Among fintech innovations, Transfer and Payment technologies have become increasingly popular. Despite these technologies' benefits, they are frequently criticized for various usage-related issues. This study uses the Modified E-Servqual and Importance Performance Analysis (IPA) methods to evaluate the service quality of Transfer and Payment applications in Indonesia. It aims to assess user perceptions and expectations, identify areas for improvement, and determine which service dimensions require enhancement. The research involved 400 respondents who used Transfer and Payment applications. To ensure reliability, the Kuder-Richardson (KR-21) formula is applied to the measurement tool, while descriptive analysis and IPA are utilized to evaluate and map service quality. Findings reveal that user perceptions of the Transfer and Payment applications are rated as ‘good,’ with an average score of 4.01 out of 5.00 (80%). User expectations are slightly lower, at 3.93 out of 5.00 (79%), but still categorized as ‘good.’ However, several attributes fall short of user expectations, particularly in Reliability, Personal Needs, User Friendliness, and Responsiveness.

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.

Abstract

This research focuses on the development and systematic redesign of a Unified Modeling Language (UML) model to represent a digital envelope-based security system. The digital envelope method, integrating both symmetric and asymmetric encryption, is employed to leverage the strengths of each encryption type, ensuring performance and security in data protection. The study enhances a previously proposed UML model by incorporating security symbols and notations tailored for security modeling, effectively capturing encryption principles while ensuring clarity and accuracy. However, several limitations were identified, particularly the lack of detailed separation between the encryption and decryption processes, which are crucial for ensuring data integrity, confidentiality, and non-repudiation. The research concludes that further development is required to refine these notations, including a clear distinction between encryption and decryption stages, and the inclusion of more detailed symbols for key management. Future work should focus on extending the notations to better address the security challenges faced by digital envelope-based systems, enhancing their representation of key generation, storage, and distribution
