Preserving Collective Memory through Architectural Transformation: Integrating Soekarno's Mentalite into Museum Design at Banceuy Prison Historic Site

Collective forgetting threatens historical memory and national identity amid globalization and rapid development. This research addresses collective memory preservation at Banceuy Prison Historic Site through architectural transformation by integrating Soekarno's mentalite into museum design as a conservation strategy. The study employs qualitative methods with descriptive, analytical, and interpretive approaches. The research examines Soekarno's architectural characteristics and mentalite during the 1926-1945 period and explores the cultural significance embedded within the site. Findings reveal that formal configuration transformation can feasibly represent collective memory at Banceuy Prison Historic Site. This transformation involves restoring prison fortress geometry and guard tower structures. It also includes applying hipped or mansard roof characteristics. Metaphorical transformation is implemented through padma ornament integration with temporal contrast expressions. Meanwhile, spatial configuration transformation through integration of remaining site structures serves solely to facilitate historical trace recording. This study contributes theoretically by developing a transformation framework that integrates collective memory theory, mentalite concept, heritage conservation principles, and architectural transformation strategies. Practically, this research provides a concrete model for developing memory-based architectural design. The model aims to preserve collective memory at historic sites through systematic transformation approaches.
