Clean and Healthy Living Behavior (CHLB) is an essential practice to improve students’ health knowledge, attitudes, and daily habits. This community service program (Kuliah Kerja Nyata/KKN) was carried out at Senior High School 8 Dumai with the aim of educating students on CHLB principles. The activity involved 47 students aged 15–17 years, using interactive methods such as presentations, educational media, discussions, and practical demonstrations. The results indicated a significant increase in students’ understanding of personal hygiene, proper handwashing with soap, maintaining a clean school environment, and adopting healthier lifestyle practices. Active participation during discussions and practice sessions showed strong engagement and relevance of CHLB education to students’ daily lives. This program demonstrated that CHLB education through KKN is effective in promoting awareness and instilling sustainable healthy behavior among high school students.
