Ajibarang Kulon Village is the administrative center of Ajibarang Subdistrict, Banyumas Regency, with strategic geographical and economic potential. Although the community has a cultural affinity for the use of traditional herbal medicine, knowledge about the use of turmeric (Curcuma longa) as an herbal remedy to boost immunity is still limited. Turmeric contains the active compound curcumin, which has antioxidant and anti-inflammatory effects and supports immune system function. Based on a preliminary survey in RT 001/RW 001 of Ajibarang Kulon Village, it was found that the community had never received any information about the benefits of turmeric for immunity and generally only used it as a cooking spice or menstrual remedy. This community service activity aims to increase community knowledge and understanding of the benefits of turmeric and how to process it as an herbal remedy to boost immunity. The methods used include integrated education through presentations, booklets, demonstration videos, and evaluation using pre-tests and post-tests. The activity was conducted on August 23 and 26, 2025, with 20 respondents. The results showed a 7% increase in knowledge, from an average pre-test score of 90% to 97% on the post-test. This activity proved effective in increasing the community's understanding of the use of turmeric as an herbal remedy to boost immunity.
