Aplikasi Informasi Penjualan Hasil Pertanian Komoditas Palawija Berbasis Mobile

The Mobile-Based Agricultural Sales Information System for Second Crops (Palawija) was developed to assist farmers and traders (toke) in Kinali District, West Pasaman Regency, in the buying and selling process of second crops. Thus far, the marketing of agricultural products has been conducted directly, making it difficult for farmers to market their harvests, while traders must physically visit locations to check stock and crop quality. To address this issue, a mobile-based application was developed to connect farmers and traders within a single platform. This study utilized the Waterfall method, which includes the stages of requirements analysis, design, implementation, testing, and maintenance. Data collection was carried out through observation, interviews, and literature reviews. The application was developed using Flutter as the mobile framework, PHP for the backend, and MySQL as the database. The system accommodates three types of users: Admins, Farmers, and Traders (Toke). The available features include crop data management, real-time stock information, market price predictions, location-based searches, crop booking, trader identity verification, WhatsApp integration, ratings and reviews, as well as transaction management by the admin. The results of the Black Box Testing demonstrated that all features within the application functioned properly and according to their intended design. With the implementation of this application, the ordering and transaction processes for second crops have become easier and more secure, thereby helping both farmers and traders conduct buying and selling activities more efficiently.
