Ethnobotany of Plants for Cleansing and Fragrancing in Jamasan Keris Used by Surakarta Community, Central Java, Indonesia

The Surakarta community practices the cultural tradition of caring for keris. This study documents traditional knowledge on plants used for cleansing and fragrance in keris care. Research was conducted from May to October 2023 through interviews, field observations, and literature reviews, with key informants selected purposively. Data were analysed thematically and quantitatively using the Relative Frequency of Citation (R.F.C.) index. Thirteen plant species, including Cocos nucifera L. and Citrus aurantiifolia (Christm.) Swingle, were essential for cleansing, while Santalum album L. was most recognized for fragrancing material. These findings highlight the importance of preserving ethnobotanical knowledge for cultural and plant sustainability.
