Design of a Cashier Application for Pak Pak Pharmacy Based on Android

Abstract

The advancement of information technology has encouraged business owners, including pharmacy stores, to shift from manual systems to digital solutions to improve operational efficiency and accuracy in data recording. Toko Obat Pak Pak previously relied on manual transaction and inventory management, which was prone to errors and delayed reporting. This study aims to design and develop an Android-based cashier application to simplify sales transaction recording, medicine stock management, and the automatic generation of daily and monthly sales reports. The development method used is the System Development Life Cycle (SDLC) with the waterfall model, utilizing Android Studio as the IDE, Java as the programming language, and SQLite as the local database system. The resulting application includes key features such as transaction processing, inventory management, sales reporting, and low-stock notifications. The testing results show that the application enhances transaction efficiency, minimizes recording errors, and provides accurate and real-time reporting. Thus, this application serves as an effective digital solution to replace the manual system at Toko Obat Pak Pak and supports better business decision-making.
