This study aims to analyze the influence of intellectual intelligence, work motivation, and work discipline on the performance of members at Atang Sendjaja Air Force Base in Bogor, both simultaneously and partially, and to determine the most dominant variables that influence performance. The research approach employs a quantitative method, utilizing a causal-comparative and explanatory research design. The research population included all 1,129 members of the Atang Sendjaja Air Force Base in Bogor, with a sample of 71 respondents selected based on job relevance and involvement in operational activities. Data were collected through questionnaires and analyzed using multiple linear regression with the help of SPSS version 25.0. The results showed that the three independent variables — intellectual intelligence, work motivation, and work discipline — had a significant effect on member performance, both simultaneously and partially. The regression coefficient values for each variable indicate a positive direction of influence, meaning that the higher the levels of intellectual intelligence, motivation, and work discipline, the better the performance of members. Among the three variables, work discipline proved to have the most dominant influence on improving member performance, as indicated by the highest regression coefficient value (0.289). This finding reinforces the view that discipline, which reflects compliance with regulations and work responsibilities, is key to building work effectiveness and efficiency in a military environment. The implication of this study is the need to improve discipline and work motivation programs integrated with intellectual intelligence development in order to support continuous performance improvement at Atang Sendjaja Air Base in Bogor.
