Islamic boarding schools, as Islamic educational institutions in Indonesia, are important in supporting health programs, especially in promoting health and cleanliness in everyday life. This service aims to increase the knowledge and awareness of Islamic boarding school students about PHBS. The service uses the SL (Service Learning) approach through counseling on Clean and Healthy Living Behavior at the Abnaul Amir Islamic boarding school, Kab. Gowa.
