Abstract
Tanaman miana (Coleus scutellarioides L. Benth) merupakan tanaman hias yang memiliki potensi sebagai antibakteri karena mengandung senyawa metabolit sekunder seperti flavonoid, tanin, dan terpenoid. Penelitian ini bertujuan untuk mengetahui efektivitas antibakteri ekstrak daun miana terhadap pertumbuhan Streptococcus mutans. Simplisia daun miana sebanyak 900 gram diekstraksi menggunakan metode maserasi dengan pelarut etanol 96% selama 3 hari, menghasilkan ekstrak kental sebanyak 111,24 gram dengan rendemen sebesar 12,36%. Uji daya hambat dilakukan menggunakan metode difusi cakram terhadap bakteri Streptococcus mutans dengan konsentrasi ekstrak 10%, 20%, dan 30%.
Hasil menunjukkan bahwa konsentrasi 10% menghasilkan zona hambat rata-rata 4,78 mm (kategori lemah), sedangkan konsentrasi 20% dan 30% menghasilkan zona hambat masing-masing 5,26 mm dan 5,37 mm (kategori sedang). Berdasarkan hasil tersebut, dapat disimpulkan bahwa ekstrak etanol daun miana memiliki aktivitas antibakteri terhadap Streptococcus mutans dengan efektivitas yang meningkat seiring peningkatan konsentrasi.
Abstract (English)
Miana plant (Coleus scutellarioides L. Benth) is an ornamental plant that has potential as an antibacterial because it contains secondary metabolite compounds such as flavonoids, tannins, and terpenoids. This study aims to determine the antibacterial effectiveness of miana leaf extract against the growth of Streptococcus mutans. Simplisia of 900 grams of miana leaves were extracted using the maceration method with 96% ethanol solvent for 3 days, producing a thick extract of 111.24 grams with a yield of 12.36%. Inhibition tests were carried out using the disc diffusion method against Streptococcus mutans bacteria with extract concentrations of 10%, 20%, and 30%. The results showed that the 10%
concentration produced an average inhibition zone of 4.78 mm (weak category), while the 20% and 30% concentrations produced inhibition zones of 5.26 mm and 5.37 mm respectively (medium category). Based on these results, it can be concluded that the ethanol extract of miana leaves has antibacterial activity against Streptococcus mutans with increasing effectiveness as the concentration increases.
