This paper intends to describe in depth the representation of the political role of political parties in strengthening local democracy in West Sumatra after returning to the regional government system that changed the political system of local government in Minangkabau. Through Regional Regulation No. 2 of 2007 concerning the Principles of Regional Government, the political system of local government in West Sumatra is based on the concept of "Basandi Syarak Customary, Syarak Basandi Kitabullah". With this concept, the implementation of regional government implemented in the context of local democracy comes from three elements, one of which is the custom of Bundo Kanduang (female figure) who represents women in the area. Representation and political role of women as part of the administration of regional government, their position is formally within the Regional Musyawwah Agency (BAMUSDA). Bundo kanduang is one of the traditional institutions which is a representation of women in the area. His main task is to preserve the culture and customs of Minangkabau based on Basandi Syarak, Syarak Basandi Kitabullah. Changes in the structure of the local government system in West Sumatra have shifted the representation and role of women who were previously only guardians of the continuity and preservation of customs.
