Abstract

Jahe merah (Zingiber officinale var rubrum) merupakan tanaman yang digunakan sebagai obat karena memiliki banyak manfaat, salah satunya sebagai antibakteri. Adanya aktivitas antibakteri dikarenakan kandungan oleoresin pada jahe merah memiliki kandungan fenol yang dapat melisiskan membran sel bakteri. Staphylococcus aureus adalah floranormal yang dapat menjadi bakteri patogen yang dalam kondisi tertentu menyebabkan infeksi ringan sampai dengan infeksi serius. Penelitian ini dilakukan untuk mengetahui pengaruh ekstrak jahe merah berbagai konsentrasi (10%, 40%, 70%, dan 100%) terhadap pertumbuhan Staphylococcus aureus in vitro menggunakan media agar Mueller-Hinton dengan metode disc diffusion. Ekstrak jahe merah dibuat dengan bubuk jahe merah yang dicampur pelarut etanol absolut menggunakan metode maserasi. Diperoleh hasil terbentuknya zona hambat pada konsentrasi ekstrak 70% dengan rata-rata sebesar 8,76 mm dan 100% dengan rata-rata 15,55 mm. Berdasarkan hasil analisis uji One Way Anova bahwa ekstrak jahe merah memiliki efektivitas antibakteri dalam menghambat pertumbuhan Staphylococcus aureus, dan daya hambat yang paling optimal yaitu pada konsentrasi ekstrak jahe merah 100%. Kata Kunci : Ekstrak, Jahe Merah, Staphylococcus aureus. / Red Ginger (Zingiber officinale var rubrum) has been used as a traditional medicine herb as an antibacterial. Oleoresin in red ginger extract contains phenol which can lyse bacterial walls, thus causing antibacterial activity. Staphylococcus aureus is a floranormal which can be a pathogen under certain conditions, causes mild infections to serious infections. This research aim to know the effect of red ginger extract in various concentrations (10%, 40%, 70%, and 100%) towards growth of Staphylococcus aureus via in vitro throught Mueller-Hinton agar medium with disc diffusion method. Red ginger extract is made with red ginger powder with absolute ethanol using maceration method. Result showed there is 70% red ginger extract concentration with an average of 8.76 mm and 100% with an average of 15.55 mm. Based on result of the One Way test, it was found that ginger extract has antibacterial effects towards the growth Staphylococcus aureus and the strongest inhibition potential is in 100%. Keywords: Extract, Red Ginger , Staphylococcus aureus.
