Development of Mobile Application to Record Activities in Longan Plantations of Farmers in Ban Doi Daen, Laoyao Subdistrict, Ban Hong District, Lamphun Province

Abstract

This research aimed (1) to develop a mobile application for recording agricultural activities in longan orchards and (2) to evaluate user satisfaction with the application. The development process applied a system development life cycle (SDLC) approach. The application was built using the Dart programming language and utilized Google Firebase services for data storage. The study’s sample group consisted of 10 longan farmers who used the mobile application, selected through purposive sampling. A user satisfaction questionnaire was employed as the research instrument, and data were analyzed using mean and standard deviation statistics. The developed system featured four main functions: (1) longan orchard data management, (2) weather forecast display, (3) task scheduling, and (4) activity history recording. The application helped farmers minimize errors, manage data systematically, and use recorded information to support decision-making. The overall user satisfaction score averaged 4.41, indicating a high level of satisfaction. In detail, the highest satisfaction was in design (mean = 4.45), followed by usability (mean = 4.43) and performance (mean = 4.27). These results demonstrate that farmers were highly satisfied with the application design, particularly its modern interface, aesthetic appeal, and ease of use.
