RANCANG BANGUN SISTEM INFORMASI E-COMMERCE BERBASIS MOBILE MENGGUNAKAN FRAMEWORK FLUTTER (STUDI KASUS: TOKO CELANA RISANDI)

Abstract

The rapid growth of digital technology has significantly shifted consumer behavior toward online shopping, yet many small and medium enterprises (SMEs) still operate conventionally. Toko Celana Risandi, a local retail business specializing in pants, faces constraints such as limited market reach and inefficient manual sales recording. This study aims to design and develop a mobile-based e-commerce application for Toko Celana Risandi using the Flutter framework and the Waterfall model. The system development encompasses requirements analysis, system design modeled with Unified Modeling Language (UML), and prototype creation. The resulting mobile application features an online product catalog, real-time stock management, and integrated digital payment gateways. The system was validated through stakeholder review, demonstrating its capability to replace manual transactions, reduce data entry human errors, expand market accessibility beyond the local area, and provide automated order notifications. This research provides a structured software blueprint and responsive interface prototype that enhances administrative efficiency and digital competitiveness for retail SMEs.
