This study aimed to identify the types of plants used as food additives by the Dayak Bakati Tribe in Segiring Hamlet, Bengkayang Regency, West Kalimantan Province. This study used descriptive methods, made direct observations at the research site, and conducted interviews with informants. The informants are women from the Dayak Bakati Tribe who use plants as food additives and live in Bengkayang Regency. Data was collected using triangulation, namely interviewing informants, observing, and documenting photographs for the documentation of the plant. Information on plants used for ingredients added to food is identified to determine the scientific name.
