Abstract

This research aims to create an educational environment integrated with technology through the implementation of educational technology, particularly by managing and storing digital learning device documents known as repositories. The developed Repository System aims to optimize storage management for learning device documents within an educational institution. A case study was conducted at a Vocational High School (SMK). The management and storage system for learning device documents was developed using the Personal Extreme Programming (PXP) method, adopting an adaptive and flexible agile approach. The repository system also applies data compression technology to optimize the storage capacity of learning device documents. Based on the results of the data compression testing, the developed system proved to be suitable, achieving an average storage efficiency of 40.04% for each uploaded file. This research contributes practical insights into the implementation of a repository system in an educational environment, particularly in Vocational High Schools, with a focus on curriculum transitions and the efficiency of managing learning device documents.

Abstract

This study details the design, development, and evaluation of an Android-based personal finance management application tailored for young adults in higher education. Addressing unique financial challenges such as limited experience and fluctuating income, the application incorporates features like income tracking, expense monitoring, budgeting, and financial goal setting. Developed using the Waterfall model, the application includes secure login systems, intuitive transaction management, customizable goals, budget projections, and automated notifications to encourage financial discipline. Usability evaluations using a 5-point Likert scale with 50 users revealed an overall satisfaction score of 4.6/5, rated 'Excellent.' Users praised the intuitive design, accurate tracking, and motivational reminders, while also suggesting additional customization and deeper financial analysis for future updates. This study demonstrates the potential of targeted digital tools to foster financial literacy and resilience, offering evidence that personalized technology can significantly improve financial behaviors in young adults. Future research will explore enhanced customization and AI-driven features to further refine the application’s impact.
