Abstract
Minor wounds are common among junior high school students, especially during physical activities and sports. A preliminary survey at Al Azhar 14 Islamic Junior High School, Semarang, showed that most students had experienced minor wounds but had limited knowledge of proper wound hygiene and infection prevention. The “Siswa Cerdas Mikrobiologi” community service program aimed to improve students’ knowledge of basic microbiology and wound care through interactive and experiential learning, in support of SDGs 3, 4, and 6. The program consisted of a pretest, interactive education sessions, hands-on science activities using microscopy and agar culture, student-created educational media, and a posttest with reflection. A total of 91 seventh- and eighth-grade students, mostly aged 13–14 years, participated. Results showed improved knowledge of wound care, with students in the good category increasing from 59% at pretest to 98% at posttest. Basic microbiology knowledge also increased from 85% to 96%. These findings indicate that microbiology-based education combined with interactive and hands-on methods can strengthen students’ health literacy in preventing wound infections. Program sustainability requires educational equipment and a formal implementation agreement with the school.
