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

Background: The availability of technological factors largely influences social media adoption as a business support tool for microenterprises worldwide. However, recent studies reveal inconsistencies in the direct influence of technological factors on social media adoption. The proposed mediating variable is essential to address those inconsistencies. Objective: This study aims to identify the mediating role of perceived initial trust in the nexus between technological factors and social media adoption. Methods: Data was collected from 200 owners or staff of Indonesian food and beverage (F&B) microenterprises using a close-ended online questionnaire. Partial least squares equation modeling (PLS-SEM) was utilized for the data analysis process. Results: Findings revealed that cost-effectiveness significantly influences social media adoption, while relative advantage and perceived compatibility have no significant direct impact. Based on the result of PLS-SEM, this study identified a full mediation role of perceived initial trust, especially for relative advantage and perceived compatibility. The presence of potential advantages and compatibility shapes users' decisions to adopt social media through their trust in the early stages.   Conclusion: This study improves the understanding of how perceived initial trust connects technological factors to social media adoption. Furthermore, our study suggests practical implications for the government to create a community of practice involving F&B microenterprise owners. This suggestion may enhance knowledge and trust in the use of social media.    Keywords: Social Media Adoption, Perceived Initial Trust, Technological Factors, F&B Microenterprises

Abstract

The development of a child's motor skills starts when a child is 0 months old to 6 years old. In general, the development of motor skills divided into fine motor development and gross motor development. Fine motor development is a development that involves small muscles to follow certain movements. An example of a game activity to help stimulate small muscle development is the Bag Toss game. This game helps stimulate fine motor development by increasing eye coordination with the hand. In addition to the types of activities that boost fine motor development, it also requires the ability to monitor, record, and process the results of children's activities to assess and analyze the status of a child's fine motor development. In this study, we developed the Bag Toss game system that connected to the Internet of Things (IoT) platform. Bag Toss game has linked with a sensor that will record children's play activities. The results of recording data will be sent to the IoT platform to be processed and presented through the internet network. The implementation of IoT for educational purposes is known as the Internet of Educational Things (IoET). The system built will be tested in terms of functionality, reading accuracy and child assessment. The functionality of the system works 100% according to predetermined component functions, as well as for 100% successful reading accuracy for the scenario of throwing distances of 1 meter and 1.5 meters. In addition, the average delay time for every hole is 0.62 seconds. The delay value can still be tolerated and does not interfere with the game when the child assessment is conducted. The child assessment involved 4 children, the results obtained that 3 children are in the Well Development (BSH) stage and 1 child in Very Well Development (BSB) stage.
