The research method used is a qualitative method, namely using observation, documentation, and interviews. At the design stage, namely star UML for system modeling, figma for interface design. Frontend uses HTML, CSS, Javascript. Backend uses PHP, Database uses MYSQL, XAMPP as a local web server and Visual Studio Code as the main editor.
