The De Javasche Bank (DJB) Cultural Heritage Building in Surabaya represents a crucial transition from the colonial financial system to national economic sovereignty through nationalization into Bank Indonesia (BI). This site serves a dual purpose as a historical artifact and an educational medium to foster a spirit of nationalism. Specifically, this relates to the Second and Third Principles of Pancasila. This article analyzes the disparity (gap) between the museum's expected educational function and the level of internalization of Pancasila values among young visitors. The research method uses a descriptive qualitative approach based on case studies. Data collection was achieved through direct observation and in-depth interviews with museum staff and visitors. The results show that the historical narrative of DJB-BI effectively describes the struggle for economic sovereignty. However, there is a disruption in the motivation for visits among students, where visits are dominated by academic demands (extrinsic motivation) rather than national awareness (intrinsic motivation). This phenomenon indicates a weakening of the essence of the Third Principle (Indonesian Unity) in the context of collective historical appreciation. The proposed strategic solutions include strengthening interactive and reflective educational programs (living history, project-based assignments) and multisectoral collaboration between museums and educational institutions. This synergy is crucial to restoring the museum's function as a space for ideological and moral character building in order to strengthen nationalism in the digital age.
