This research aimed to develop and evaluate an Internet of Things (IoT) - based irrigation system titled “Watering Intelligent System with Integrated Control agricultural research and education. Despite this agricultural (WISIC): An IoT - based Crop Watering System,” prowess, challenges persist in optimizing irrigation practices to meet designed to optimize crop watering processes. Using a modern agrarian demands. descriptive - developmental method, the study was Recognizing this need, the "Watering Intelligent System with conducted at Iloilo State University of Fisheries Science Integrated Control (WISIC): An IoT - based Crop Watering System" and Technology – San Enrique Campus from August to project takes root within ISUFST - SEC. Drawing inspiration from November 20 24. The development adhered to the the region's agricultural heritage and fueled by the university's vision System Development Life Cycle (SDLC) - Rapid of advancing agrarian technology, WISIC aims to revolutionize Application Development (RAD) model. A usability test irrigation practices within and beyond the campus grounds was conducted using a standardized questionnaire checklist by John Brooke (1986), with respondents comprising four (4) purposively selected faculty II. METHODOLOGY members and twenty - five (25) students who were Research Design chosen randomly. Data collected were analyzed using the System Usability Scale (SUS), where WISIC This study employed the descriptive - developmental research achieved an SUS score of 95.60, denoting an “A+” grade method. Descriptive research refers to a statement of conditions within the 96 - 100 percentile range. The system was during the survey, with the researcher having no control over the described as “Best Imaginable” and “Acceptable,” with variables. Descriptive studies aimed to determine, describe, or a Net Promoter Score categorizing it as “Promoter.” id entify 'what is.' At the same time, analytical research sought to establish 'why' or 'how' it came to be. The primary purposes of
