Usability Evaluation of SIFOSA Using the System Usability Scale (SUS) Method

Abstract

Digital transformation in education is essential for achieving Sustainable Development Goal 4 (Quality Education), particularly in rural areas where digital literacy remains low. However, limited technological literacy among educators and students in these areas presents a significant challenge in adopting digital tools. This study evaluates the usability of the Nature School Information System (SIFOSA), implemented at the Darul Furqan Foundation in Air Santok Village, Pariaman. The evaluation focuses on how effectively SIFOSA can support administrative and academic processes in a nature-based, IT-oriented, and Islamic boarding school environment. Using the System Usability Scale (SUS) method, data was collected from teachers, administrators, and students with varying levels of technological proficiency. The system obtained a SUS score of 78.5, which categorizes it as "good" in terms of usability. These findings indicate that SIFOSA is functionally robust and user-friendly, even in contexts with low digital literacy. The study concludes that SIFOSA has strong potential to improve digital literacy and operational efficiency in rural schools, and can serve as a model for similar educational environments aiming to implement user-centric digital systems.
