Currently, public trust in the Indonesian National Army (TNI) is decreasing, especially due to issues of accountability, integrity, and meritocracy. In this uncertain situation, the socialization of the TNI Law is a strategic step to improve the image of the TNI in the eyes of the public. Changes to the TNI Law are expected to bring great benefits, especially in increasing transparency, accountability, and the implementation of a meritocratic system in the TNI structure. However, the public wants to ensure that these changes are truly far from the practice of injustice and personal interests within the TNI. This study aims to see how effective the socialization of the TNI Law is in overcoming the crisis of public trust. In addition, this study also produces various views on the implementation of the TNI Law and assesses how the socialization of the Law can affect public perceptions of professionalism and trust in the TNI. The results of a simple linear regression test show that the socialization of the TNI Law has a significant effect on the level of public trust, with a sig value (0.001). The R Square value of 0.301 indicates that the socialization of the TNI Bill is able to explain 30.1% of the variability in public trust, while the rest is influenced by other factors outside the model. Thus, socialization that is carried out openly, participatively, and accountably is an important step in bridging the current crisis of trust. The findings of this study provide critical insights and are expected to be implemented effectively to improve public trust in the TNI institution in the future.
