<![CDATA[This article examines the history, development, and cultural preservation strategies of the Ikatan Keluarga Koto Tuo Jakarta Raya (IKKJR), a Minangkabau diaspora organization based in Jakarta. Using a socio-historical method encompassing heuristics, source verification, interpretation, and historiography, as well as Karl Mannheim's generation theory as an analytical framework, this study explores three main issues: the historical formation of IKKJR, the factors inhibiting its optimal role as a cultural guardian, and the strategies it employs to bridge the cultural understanding gap between older and younger generations. The findings reveal that IKKJR evolved from informal kinship gatherings in the 1950s into a formally structured organization, reaching its institutional peak during the leadership of Drs. Daturrahman Dahlan, MM (2002–2005). Four main inhibiting factors were identified: insufficient customary knowledge among younger generations, intergenerational gaps in cultural interpretation, the influence of modernization, and cultural assimilation in Jakarta's multicultural environment. To address these challenges, IKKJR employed several strategies including periodic customary lectures, arts and entertainment activities as cultural media, involving youth in organizational committees, and strengthening family bonds through regular gatherings. This study concludes that the generational gap within IKKJR is a natural consequence of institutional transformation, and the organization's sustainability depends on its ability to balance the preservation of Minangkabau adat values with modern governance demands.]]>
