Development of an Android-Based Financial Management Information System for Boarding Houses Using the Rapid Application Development (RAD) Method

Summary/Abstract: The rapid advancement of technology has significantly transformed daily human life, particularly through the widespread use of smartphones to simplify various tasks. In response to this technological shift, Kost XYZ, a women’s boarding house located in Central Jakarta, aims to enhance its operational efficiency. The boarding house faces challenges such as varying room facilities, inconsistent rental rates, non-permanent tenants, and manual record-keeping, all of which frequently result in delayed payments. To address these issues, this study proposes the development of an Android-based financial management information system using the Rapid Application Development (RAD) methodology. The system was built using Kotlin programming language via Android Studio and integrated with Firebase for data storage. Its design provides separate interfaces for owners and tenants: the owner system focuses on boarding house operations, while the tenant system facilitates payment management. Usability testing was conducted using five metrics—learnability, efficiency, memorability, error rate, and satisfaction—with direct user involvement. The results indicate that the system is feasible and performs well across all usability aspects. A satisfaction score of 73.5 places the system in the “good” category, demonstrating user acceptance and the system’s effectiveness in supporting real-time operational and financial monitoring.
