Abstract

ABSTRAK Tanaman kemangi banyak dimanfaatkan oleh masyarakat untuk pengobatan infeksi khususnya bagian daun. Hal ini dikarenakan daun kemangi memiliki senyawa aktif seperti minyak atsiri, alkaloid, saponin, flavonoid, triterpenoid, steroid, tannin dan fenol yang dapat menghambat pertumbuhan bakteri. Tujuan penelitian ini dilakukan untuk mengetahui ada tidaknya aktivitas, mengetahui diameter zona hambat dan mengetahui klasifikasi kekuatan aktivitas daya hambat antibakteri ekstrak etanol daun kemangi. Jenis penelitian ini adalah penelitian eksperimental dengan metode difusi lubang sumuran dengan teknik pengambilan sampel adalah purposive sampling.  Konsentrasi ekstrak yang digunakan yaitu konsentrasi 100%, 80%, 60%, 40%, 20%, sedangkan untuk kontrol positif digunakan klindamisin 30µg, dan kontrol negatif yang digunakan etanol 96%. Hasil diameter zona hambat yang terbentuk diukur dengan jangka sorong. Hasil penelitian menunjukkan bahwa ekstrak etanol daun kemangi memiliki aktivitas dalam menghambat pertumbuhan bakteri Staphylococcus aureus dengan diameter rata-rata yang didapat dari setiap perlakuan yaitu 100% (10,08 mm), 80% (8,10 mm), 60% (6,49 mm), 40% (4,29 mm), 20% (2,26 mm), dan sebagai klasifikasi kekuatan aktivitas daya hambat antibakteri yaitu pada konsentrasi 100% kuat, 80%-60% sedang dan 40%-20% lemah. Kata Kunci : Daun kemangi, Ekstrak, Difusi, Staphylooccus aureus  ABSTRACT Part of the basil plant (Ocimum sanctum L.) that widely used by people for treatment of infections is basil leaves. This is because basil leaves have active compounds such as essential oils, alkaloids, saponins, flavonoids, triterpenoids, steroids, tannins and phenols which can inhibit bacterial growth. This research aimed to find out the presence or absence of activity, to determine the diameter of the inhibitory zone and the classification of antibacterial mention against what the name of bacterial is activity of ethanol extract of basil leaves. The type of this research is experimental research with a well diffusion method with sampling technique is purposive sampling. The concentration of extracts used were concentrations of 100%, 80%, 60%, 40%, 20%, while as positive control is  clindamycin 30µg, and the negative control used 96% ethanol. The resulting diameter of the inhibition zone is measured by the calipers.  The results showed that the ethanol extract of basil leaves had an activity in inhibiting the growth of Staphylococcus aureus bacteria with an average diameter obtained from each treatment that was 100% (10,08mm); 80% (8,10mm); 60% (6,49mm); 40% (4,29mm); 20% (2,26mm), and as the antibacterial activity classification, that were strong in 100% of extract concentration, medium in 60-80% of extract concentration, and weak in 20-40% of extract concentration. Keywords : Basil leaf, Extract, Diffusion, Staphylooccus aureus
