ABSTRACT : This study aims to examine the effect of organizational restructuring, transformational leadership, and adaptive organizational culture on organizational effectiveness, with adaptive capability as a mediating variable and environmental dynamism as a moderating variable. The research was conducted at state universities with legal entity (PTNBH) status in Central Java, namely Diponegoro University, Sebelas Maret University, and Universitas Negeri Semarang. A total of 240 structural officials participated as respondents. Data were collected through questionnaires and analyzed using Structural Equation Modeling with Partial Least Squares (SEM-PLS) using SmartPLS 4 software. The results indicate that all three independent variables significantly affect organizational adaptive capability. Furthermore, adaptive capability has a significant effect on organizational effectiveness and mediates the relationship between the independent variables and effectiveness. Environmental dynamism significantly moderates the effect of adaptive capability on organizational effectiveness
