RANCANG BANGUN APLIKASI MANAJEMEN MEMBER GYM BERBASIS MOBILE (Studi Kasus: Sunu Gym)

The fitness industry is experiencing significant growth due to increasing public awareness of healthy lifestyles. However, many gyms, including SunuGym, face challenges in membership management due to manual methods that lead to inefficiencies and recording errors. This study aims to design and develop an mobile-based gym membership management application to address issues at SunuGym, as well as to test and evaluate its functionality. The application was developed using a design science approach, incorporating features such as registration, membership renewal, and real-time data monitoring with a cloud database. Testing was conducted using Blackbox Testing to verify feature functionality and User Acceptance Testing (UAT) to assess user acceptance. The results show that all features function as specified, with UAT scores of 96% for admin roles and 95.51% for user roles, indicating that the application meets user needs. The application enhances membership management efficiency, reduces recording errors, and supports data-driven decision-making at SunuGym. This study provides a foundation for future feature enhancements, such as fitness analytics, to improve gym competitiveness in the digital era.
