This study aims to see what the participation of coastal communities in Bintan and Kota Tanjungpinang Regencies is like and how the concept of reconstruction of the electoral law in increasing the involvement of coastal communities in simultaneous elections in Indonesia. This study is normative legal research with a statutory, moral, and conceptual approach.
