Abstract

The adoption of Clean and Healthy Living Behaviors (CHLBs) at MI Muhammadiyah Paremono remains a challenge, primarily due to students' low awareness of hygiene, minimal health practices within the school environment, and limited access to interactive learning media. This community engagement program aimed to enhance students' understanding and adoption of CHLBs through a Science, Technology, Engineering, and Mathematics (STEM) approach. The activities included developing a STEM-based health module, providing teacher training, socializing CHLBs among students, and promoting hygiene practices within the school environment. Learning was delivered interactively through experiments and project-based methods, such as a handwashing simulation using pepper powder to represent germs and the use of the HealthHeroes application to assess the nutritional value of food. The program's effectiveness was evaluated through observation, pre-tests and post-tests, and satisfaction surveys for teachers and students. The results showed a significant average increase of 35.2% in students' understanding of CHLBs, along with an improvement in their hygiene-related behaviors. Teachers also reported feeling more confident in delivering STEM-based health education. As a follow-up, the school will receive a self-evaluation guide and continuous support to ensure CHLB practices are embedded in the school culture. This program is expected to create a sustainable positive impact on health and hygiene within the school environment.

Abstract

Penggunaan antibiotik konvensional sering kali kurang efektif karena bakteri dapat membentuk biofilm yang mempersulit pengobatan. Penelitian mengenai terapi alternatif menggunakan bahan alami yang memiliki aktivitas antibakteri semakin berkembang. Salah satu bahan alami yang menjanjikan adalah ekstrak daun ungu Graptophyllum pictum (L.). Tanaman ini telah digunakan secara tradisional dalam pengobatan di Asia Tenggara dan mengandung senyawa bioaktif seperti flavonoid, alkaloid, dan terpenoid yang berfungsi sebagai agen antibakteri. Selain itu, madu lebah klanceng juga memiliki sifat antibakteri karena mengandung senyawa seperti hidrogen peroksida, flavonoid, dan asam fenolat. Penelitian ini bertujuan untuk mengetahui efektivitas salep yang mengandung ekstrak Graptophyllum pictum (L.) dan madu lebah klanceng terhadap Pseudomonas aeruginosa. Tiga formula salep diuji berdasarkan diameter zona hambat, yaitu: F1 dengan hambatan 23,42 mm (konsentrasi tinggi), F2 dengan hambatan 14,10 mm (konsentrasi sedang), dan F3 dengan hambatan 13,12 mm (konsentrasi rendah). Hasil penelitian menunjukkan bahwa formula F1 memiliki daya hambat terbesar terhadap P. aeruginosa, diikuti oleh F2 dan F3. Formula dengan konsentrasi lebih tinggi menunjukkan potensi antibakteri yang lebih kuat. Hasil ini menunjukkan bahwa kombinasi ekstrak Graptophyllum pictum (L.) dan madu lebah klanceng, terutama pada konsentrasi tinggi, berpotensi menjadi agen antibakteri yang efektif untuk mencegah infeksi luka.
