Abstract

The present study focuses on the design and implementation of a website-based e-commerce information system for agricultural product marketing in Talawaan District. The research addresses the limited market access and digital marketing adoption among local farmers by developing a comprehensive e-commerce platform. The system's design employed the Rapid Application Development (RAD) methodology, undergoing iterative processes that encompassed requirements analysis, system design utilizing DFD and ERD, implementation, and Black Box Testing. The developed e-commerce system incorporates features such as product management capabilities, integrated payment methods, seller dashboards, and user-friendly interfaces tailored to farmers' technical capabilities. The findings indicate the efficacy of the system in digitalizing agricultural marketing processes, thereby empowering farmers to autonomously manage their products and expand their market reach without the need for intermediaries. The implementation has demonstrated positive impacts on farmers' digital literacy and product competitiveness. This research contributes to the digital transformation of agricultural marketing in rural areas and provides a replicable model for similar contexts

Abstract

This paper discusses the development and implementation of a website for GMIM Bait-El Kamasi and GMIM Bait-Lahim Talete churches to address communication challenges faced by the congregation. The main problem identified was the reliance on in-person announcements and the unstructured use of social media, which limited access to important church information for members who could not attend services regularly. Based on interviews and surveys, 92% of the congregation expressed the need for a digital platform, with 85% believing it would improve information dissemination and engagement.The solution was to create a user-friendly website that provides real-time updates on worship schedules, announcements, and church activities. Additionally, the website includes a dedicated section for church history and prayer services. Church staff and youth representatives were trained to manage the website, ensuring ongoing content updates and technical maintenance. Regular evaluations will be conducted to assess the website’s effectiveness in improving church communication and participation.This project demonstrates the importance of integrating technology in church operations to enhance engagement and ensure accessibility. The website is expected to have a lasting impact by fostering a more connected church community and addressing the evolving digital needs of its members.
