ETHNOBOTANICAL SURVEY OF MEDICINAL PLANTS USED TO TREAT CHRONIC KIDNEY DISEASE IN THE SUKASARI REGION, PURWAKARTA, WEST JAVA, INDONESIA

Chronic kidney disease (CKD) is a common progressive disease that is typically characterized by the permanent loss of nephrons and an eventual decline in glomerular filtration rate. CKD increases mortality and has a significant impact on the quality of life and the economy, which is becoming a major public health issue worldwide. This research aims to document and preserve the use of ethnomedicinal to treat CKD by communities in the Sukasari Region, Purwakarta, West Java, Indonesia. Fieldwork was carried out from April to May 2026 using direct interviews, questionnaires, and discussions. Plant species are identified based on standard taxonomic methods, flower morphological characteristics, and where possible, using samples for comparison, as well as consultation with experts and the literature. The plant types obtained were grouped into families according to the Cronquist classification system. Plant names were checked against the Plant List (www.plantlist.org) and the International Plant Name Index (www.ipni.org). This research reports that 30 plant species are commonly used by people in the Sukasari Region to treat CKD. Among the various plant parts used, leaves (60.0%) are most frequently used in making medicines, followed by rhizomes (16.7%), fruit (10.0%), rind (6.7%), stem, and bark (respectively 3.3%). Meanwhile, the most frequently used preparation methods were decoction (63.3%), followed by infusion (23.3%), and juice (13.3%). The results of this research confirm that people in the Sukasari Region still rely heavily on medicinal plants for their health care system, especially for the treatment of CKD with the most frequently used parts of the leaves and their use in decoctions and infusions.
