Development of a Kakeibo-Based Financial Recording Application Using the Mobile-D Method

Abstract

Good financial management is an important key in maintaining individual economic stability, especially for Generation Z, who often face challenges in financial literacy. This research aims to build an Android-based financial recording application by applying the Kakeibo method, a traditional technique from Japan that helps users manage budgets through four main categories: survival, optional, culture, and extra. The system is developed using the Mobile-D method, which consists of five main phases: explore, initialize, productionize, stabilize, and system test and fix. The test results show that the application is able to function according to user needs, providing convenience in recording transactions, making reports, and managing budgets efficiently. This research successfully produced an application that can improve users' financial literacy, help them manage their finances in a more structured manner, and provide practical and modern digital solutions for the younger generation
