Sports participation plays a crucial role in promoting physical health and supporting Sustainable Development Goal 3 (Good Health and Well-Being). However, limited access to sports equipment and sports facilities often hinders community engagement in healthy activities. This study proposes the design of a sport equipment rental and sport field booking application as a digital solution to increase accessibility and convenience for the public. The application integrates features such as online booking of sports fields, rental of various sports equipment, payment gateway, and real-time availability tracking. By adopting user-friendly design principles, the platform aims to encourage active participation in sports while reducing barriers related to cost and accessibility. Furthermore, the system supports community health by fostering inclusivity and creating opportunities for individuals to engage in regular physical activity. The proposed application is expected to not only optimize resource utilization but also contribute to achieving SDG 3 by improving public health outcomes through increased participation in sports and physical exercise.
