Evaluation of Smart Agriculture Prototype using SUS Method

Abstract

Agriculture plays a strategic role in Indonesia’s economy. However, the adoption of digital farming technology among farmers remains low due to limited digital literacy and complex application interfaces. This paper proposes a mobile-based smart farming application for real-time agricultural monitoring. We develop the system using the prototyping approach to ensure the application meets farmers’ practical needs. The application monitors environmental parameters such as temperature, humidity, and light intensity. We verify system functionality using Black Box testing on five main features: registration, login, monitoring, data storage and visualization, and notification services. The results show that all tested features operate correctly according to the designed scenarios. We evaluate system usability using the System Usability Scale (SUS) involving 10 farmer respondents aged 23–70 years. The analysis produces a total contribution score of 18.4 for positive statements and 16.0 for negative statements. The SUS calculation results in a final usability score of 86. This value exceeds the global average SUS benchmark of 68 and indicates a high level of usability and strong user acceptance. These results show that the proposed application functions reliably and provides a user-friendly interface for farmers. The high SUS score confirms that the system supports practical use in agricultural monitoring and can assist farmers in accessing environmental information efficiently.
