Abstract

This study aims to design and evaluate the integration of a Tuition Fee (UKT) payment feature using the DANA digital wallet into the Academic Information System (SIAKAD) of UIN Sumatera Utara to improve the efficiency of academic services. The system was developed using the Waterfall method. System evaluation was conducted through User Acceptance Testing (UAT) at the Alpha Testing stage using nine predefined test scenarios involving internal users. The testing results indicate that all nine test scenarios were successfully completed, achieving a 100% success rate. These results confirm that the system meets the specified requirements and user needs. The novelty of this study lies in the integration of a UKT payment feature using the DANA digital wallet directly into the SIAKAD of UIN Sumatera Utara, providing a practical and integrated digital payment alternative.

Abstract

This study discusses the development of a web-based sales information system to support the operations of Micro, Small, and Medium Enterprises (MSMEs) by applying the Waterfall methodology. The developed system includes main features such as product management, transaction processing, sales reporting, and user authentication. Manual testing using 10 test scenarios showed a functional success rate of 80%. The system implementation was able to speed up transaction time from five minutes to approximately forty-five seconds and reduce manual input errors by up to 75%. Usability evaluation using the System Usability Scale (SUS) resulted in a score of 84, indicating a very high level of user acceptance. The results of this study show that a web-based sales information system developed using the Waterfall approach can improve efficiency, accuracy, and effectiveness in managing sales for MSMEs.

Abstract

Boutique Boutique digital agencies frequently encounter operational bottlenecks caused by disjointed workflows and reliance on manual data handling. Using Agency XYZ as a case study, this research identifies critical issues such as asset-caption mismatches and data security vulnerabilities arising from unmanaged 'Bring Your Own Device' (BYOD) practices. To address these challenges, this study applies the TOGAF Architecture Development Method (ADM) to design a comprehensive Enterprise Architecture tailored for small organizations. The resulting solution presents a blueprint for a centralized, web-based information system that seamlessly integrates with existing Google Workspace infrastructure and WhatsApp notifications. Key contributions of this design include an automated 'auto-switch' task delegation mechanism to prevent bottlenecks and a unified data model that establishes a Single Source of Truth (SSOT). The proposed architecture is projected to significantly reduce coordination latency, mitigate human error, and establish a secure, scalable operational framework for small creative teams.
