Rancang Bangun Aplikasi Kasir “Gorenganku” Berbasis Android pada Gorengan Rahayu

Abstract

The process of recording sales transactions in micro, small, and medium enterprises (MSMEs) that is still carried out manually often causes several problems, such as transaction delays, calculation errors, difficulties in stock management, and the risk of losing sales data. This study aims to design and develop an Android-based cashier application called “Gorenganku” as a digital solution to support the operational activities of Gorengan Rahayu. The system was developed using the Agile method because it is flexible and adaptive to changes in user requirements during the development process. SQLite was used as the main database for local data storage, while Google Sheets was utilized as a cloud-based backup medium through Google Sheets API integration. The main features of the application include sales transaction recording, product and stock management, cash and digital payment methods, and automatic sales report generation. System testing was conducted using the black-box testing method to ensure that all application functions operated according to the system design. The testing results showed that all main system features functioned properly, including transaction processing, real-time stock updates, and backup data synchronization. The implementation results indicate that the application is able to improve operational effectiveness and simplify sales data management compared to the previous manual method.
