Abstract

Clean water is water used for daily needs with quality that meets hygiene requirements. Poor environmental sanitation can increase the deposit of microorganisms in water. Water containing microorganisms can cause diarrhea. Diarrhea is still a health problem in Demta District, and one of the contributing factors is the consumption of water contaminated with Escherichia coli bacteria. Demta is a district in Jayapura Regency, which consists of several villages, including Kampung Ambora, Demda, Kamdera, Muaif, Muris Kecil, Yakore and Yaugapsa. Based on a survey in the Demta District, household activities, cooking, washing and drinking water come from mountain waterfalls which are channeled through pipes to homes. Based on the results of research on water samples in Demta District, Jayapura Regency in 2023, it was found that 5 samples did not meet the requirements (positive for bacteria Escherichia coli and coliforms). This community service aims to disseminate research results to the public in order to prevent the spread of diseases caused by bacteria Escherichia coli and coliforms. This community service was carried out for 6 months in Demta District, Jayapura Regency in June - November 2024. Activities carried out ranged from surveys, outreach and education on research results, handling water through boiling for the community before consumption.

Abstract

Kombucha merupakan minuman fermentasi yang dibuat dari campuran teh dan gula dengan menggunakan kultur simbiotik bakteri dan ragi (Symbiotic Culture of Bacteria and Yeast/SCOBY). Proses fermentasi menghasilkan berbagai senyawa bioaktif, seperti polifenol, asam organik, vitamin, dan enzim, yang berpotensi memberikan efek biologis, termasuk aktivitas antibakteri. Penelitian ini bertujuan untuk mengetahui efektivitas antibakteri teh kombucha roselle (Hibiscus sabdariffa L.) terhadap pertumbuhan bakteri Staphylococcus aureus. Jenis penelitian ini adalah deskriptif eksperimental dengan uji laboratorium menggunakan metode difusi agar Kirby–Bauer. Media yang telah diinokulasi dengan bakteri Staphylococcus aureus diuji menggunakan sampel kombucha roselle dengan tiga kali pengulangan, antibiotik sebagai kontrol positif, dan akuades steril sebagai kontrol negatif, kemudian diinkubasi pada suhu 37°C selama 24 jam. Hasil penelitian menunjukkan bahwa kombucha roselle menghasilkan diameter zona hambat rata-rata sebesar 14 mm, yang termasuk dalam kategori daya hambat kuat terhadap pertumbuhan bakteri Staphylococcus aureus. Berdasarkan hasil penelitian, dapat disimpulkan bahwa teh kombucha roselle memiliki aktivitas antibakteri terhadap bakteri Staphylococcus aureus sehingga berpotensi dikembangkan sebagai antibakteri alami.
