DEVELOPMENT AND USABILITY TESTING OF MOBILE APPLICATION ON EXERCISE MANAGEMENT FOR PREGNANT WOMEN IN INDONESIA

Abstract

Aims: This study aimed to develop and evaluate the usability of a mobile application, GoPEx, designed to promote structured exercise and behavioral interventions among pregnant women in Indonesia.

Methods: The GoPEx application was developed using the Software Development Life Cycle (SDLC) methodology, incorporating user-centered design principles and behavior modification theories such as the Health Belief Model. Content was adapted from evidence-based guidelines and tailored for Indonesian women. Usability testing was conducted with ten pregnant women in their second trimester using the System Usability Scale (SUS) and task completion assessments. Data were analyzed using descriptive statistics.

Results: The mean SUS score was 81.5 (SD = 6.3), indicating good usability, with 60% of participants rating the application as "excellent." Task completion rates exceeded 90% for most functionalities, though minor issues were noted with navigation and video-loading times. Participants provided positive feedback on the application’s design, intuitiveness, and relevance, emphasizing its potential for promoting physical activity during pregnancy.

Conclusion: The GoPEx application demonstrated strong usability and effectiveness in supporting pregnant women with exercise management. While minor technical improvements are necessary, this study highlights the potential of culturally tailored mHealth interventions to enhance maternal health in Indonesia.
