PENGGUNAAN METODE WATERFALL DALAM RANCANG BANGUN SISTEM INFORMASI MONITORING STOK TOKO OBAT PUTERA WARNA JAYA

This study addresses the issue of manual record-keeping at Putera Warna Jaya Pharmacy, which often leads to data management errors. The primary objective is to design a web-based information system that enhances accuracy, simplifies inventory management, supports purchasing and sales processes, and facilitates efficient and structured monitoring of medicine expiration dates. The development process follows the waterfall model, comprising the phases of requirement analysis, system design, implementation, and testing. The main focus is on creating a webbased stock monitoring system tailored to the pharmacy's operational needs, replacing ineffective manual recording methods. The results indicate that the system was successfully developed and runs optimally without significant issues. All key features function properly, as confirmed through black-box testing, and the interface is simple and user-friendly. Therefore, the system is considered suitable for supporting daily operations efficiently. For future development, it is recommended to add features such as minimum stock level notifications, expiration date tracking, a mobile version for easier access, and enhanced security with twofactor authentication and user activity logging. Additionally, an automatic data backup feature is crucial in preventing data loss due to system failures.
