This study aims to design and implement a web-based e-commerce application for Aidan Akika Farm in Sidodadi Village, Batang Kuis, to support the digitalization of marketing, ordering, and sales transaction management for livestock. The system was developed using the Waterfall method, comprising the stages of requirements analysis, design, implementation, testing, and maintenance. Research data were gathered through direct observation, interviews with Aidan Akika Farm personnel, and a literature review. The study resulted in an e-commerce application featuring user registration and login, product display, a shopping cart, ordering, payment processing, order details, and administrative management of order and transaction data. Testing results indicate that the system's core functions operate correctly in the test environment and are capable of presenting information and transaction summaries in a structured manner. The system interface enables both customers and administrators to facilitate ordering processes and manage transaction activities. The developed application provides a digital platform for Aidan Akika Farm to manage product and transaction information and holds the potential to support market expansion. Future development could focus on enhancing security, inventory management, user verification, and system stability.
