Development of Traceability for a Chemical-Free Vegetables System using a QR Code

Abstract

Farmers at Ban Kaset Jun La Pan require the cultivation of chemical-free vegetables with less pesticides and bio stimulants in order to provide safety for farmers and consumers. An information system was designed and implemented to meet this requirement by taking advantage of a QR code. This system enables traceability of agricultural products, from production to storage. The research objectives were as follows. - 1) to develop traceability of chemical-free vegetables via a QR code system and 2) to evaluate the efficiency of traceability of agricultural products using experts. The system was designed in a way that the administrator had full access to the system, and farmers were given permission to manage their own data. Both smartphones and computers were supported. The consumer could access the stored data using an application that supported a QR code to scan and show the farm’s name, phone number, vegetable profiles, cultivation details, origins of products, and profiles of vegetables in the same batch. The application could then direct consumers to the web application. Evaluation by the experts indicated that the average score was was at the highest level (=4.60, SD=0.51); the system could provide a production data center that meets a variety of user requirements.
