Abstract: This study aims to analyze the influence of individual characteristics, organizational justice, and work ability on member performance, and identify the most dominant variable affecting the performance of Air Force Academy members. The research location was at the Yogyakarta Air Force Academy. Data analysis techniques used descriptive methods and multiple linear regression analysis. The results showed that individual characteristics, organizational justice, and work ability significantly influence Yogyakarta Air Force Academy member performance. Both simultaneously and partially, the three variables shape optimal member performance. Good individual characteristics support members' ability to work together, communicate, and complete tasks effectively. Organizational justice also plays an important role, where fair treatment from superiors and fellow members creates a comfortable work environment and motivates members to work better. Among the three variables, work ability shows the most dominant influence. Work ability, which includes knowledge, skills, and experience, has significantly impacted the quality and productivity of members' performance at the Yogyakarta Air Force Academy. This research is expected to contribute by emphasizing the importance of fostering individual characteristics, consistent application of organizational justice, and improving work ability as the main factors in supporting the optimal performance of members at the Yogyakarta Air Force Academy. In addition, this study encourages the exploration of other variables that have the potential to influence member performance.
