Abstract

ABSTRAK Daun saliara merupakan tanaman liar yang bisa digunakan sebagai obat tradisional salah satunya infeksi kulit. Sedangkan, bakteri penyebab infeksi kulit salah satunya yaitu Staphylococcus aureus. Tujuan dari penelitian ini yaitu untuk mengetahui apakah ekstrak etanol 70% daun saliara dapat menghambat pertumbuhan bakteri Staphylococcus aureus. Penelitian ini dilakukan dengan metode eksperimen terhadap bakteri Staphylococcus aureus dengan menggunakan metode Kirby-Bauer. Dari hasil penelitian diperoleh bahwa ekstrak etanol daun saliara dapat menghambat bakteri Staphylococcus aureus dengan konsentrasi daya hambat optimum yang sebanding dengan oxacillin yaitu konsentrasi 60%, 80% dan 100% dengan rata-rata diameter 13 mm, 19,75 mm dan 20,50 mm dan dikategorikan sensitive, pada konsentrasi 20% dan 40% didapatkan hasil zona hambat rata-rata sebesar 11 mm dan 12 mm dikategorikan intermediet. Berdasarkan hasil penelitian yang telah dilakukan dapat ditarik kesimpulan bahwa ekstrak etanol 70% daun saliara dapat menghambat pertumbuhan bakteri Staphylococcus aureus. Kata Kunci: Ekstrak etanol daun saliara, Antibakteri, Staphylococcus auereus. ABSTRACT Saliara leaf is a wild plant that can be used as traditional medicine, one of which is skin infections. Meanwhile, one of the bacteria that causes skin infections is Staphylococcus aureus. The purpose of this study was to determine whether the ethanol extract of 70% saliara leaves can inhibit the growth of Staphylococcus aureus bacteria. This research was conducted with an experimental method against Staphylococcus aureus bacteria using the Kirby-Bauer method. The results showed that the ethanol extract of saliara leaves can inhibit Staphylococcus aureus bacteria with an optimum inhibitory concentration comparable to oxacillin, namely 60%, 80% and 100% concentrations with an average diameter of 13 mm, 19.75 mm and 20.50 mm and categorized as sensitive, at a concentration of 20% and 40% the results obtained an average inhibition zone of 11 mm and 12 mm were categorized as intermediates. Based on the results of the research that has been done, it can be concluded that the ethanol extract of 70% saliara leaves can inhibit the growth of Staphylococcus aureus bacteria. Keywords: Saliara leaf ethanol extract, Antibacterial, Staphylococcus auereus.
