UJI AKTIVITAS ANTIBAKTERI EKSTRAK ETANOL DAUN KEMANGI (Ocimum basilicum L.) TERHADAP BAKTERI Streptococcus mutans

Abstract

Introduction: Basil leaf (Ocimum basilicum L.) is one of the most accessible natural plant in Asia such as Indonesia. Basil leaf vegetation contains a lot of flavonoid compounds and essential oils that have the effect as antibacterial because it can inhibit the growth of bacteria Streptococcus mutans cause dental caries. Streptococcus mutans is a round gram-positive bacteria that typically form pairs or chains during its growth. The purpose of this research is to know the antibacterial effectivity of ethanol extract of basil leaves (Ocimum basilicum L.) on the growth of Streptococcus mutans bacteria.This research was conducted with laboratory experimental research method. Basil lean ethanol extract was prepared by using maseration extraction method. Method: The method used in the inhibitory test using diffusion of the disc with 5 samples in each treatment group. The sample consisted of 5 treatment groups, ethanol extract of basil leaves with concentration of 100%, 80%, 60%, 40% and 20%. Result: The result of this study showed that ethanol extract of basil leaves with 100% concentration had inhibitory power of 10,26 mm (strong category), 80% of 9,65 mm (medium category), 60% by 8,12 mm (medium category), 40% by 7,33 mm (medium category), and 20% by 6,90 mm (medium category). Conclusion: The conclusion of this research proves that basil leaf ethanol extract has antibacterial power agains Streptococcus mutans bacteria with effective concentration is 100% with strong category equal to 10,26 mm.

“…Simplisia yang sudah kering dilakukan sortasi ulang untuk memisahkan kotoran yang tidak dibutuhkan dalam pengujian, bahan organik asing, dan simplisia yang rusak karena proses sebelumnya (Fadhli et al, 2021). Selanjutnya simplisia diserbukkan dengan tujuan untuk memperkecil ukuran sehingga dapat memperbesar luas permukaan partikel dan mengoptimalkan kontak antara sampel dengan pelarut sehingga pelarut akan mudah masuk kedalam sel simplisia untuk perpindahan zat aktif (Syarifuddin et al, 2020).…”

AKTIVITAS ANTIBAKTERI EKSTRAK ETANOL DAUN DAN BATANG KEMANGI (Ocimum basilicum) SERTA FRAKSI AKTIFNYA TERHADAP Staphylococcus epidermidis

“…Pengeringan daun dan batang sebelum ekstraksi bertujuan supaya kandungan air yang ada di tumbuhan hilang sehingga bahan menjadi awet dan tidak mudah ditumbuhi mikroba. Penyerbukan daun dan batang sebelum ekstraksi bertujuan menjadikan permukaan lebih luas supaya mempermudah cairan yang berasal dari penyari untuk masuk kebagian dalam sel daun dan proses perpindahan zat yang aktif yang berasal dari serbuk menuju cairan penyari (Aminah et al, 2020).…”

Anti-Bacterial Effectiveness Test of Basil Leaf Extract (Ocimum basilicum L.) Against Escherichia coli

“…Basil leaves come from the division of spermatophyta, dicotyledonous class, order amaranthaceae, genus ocimum and species Ocimum basilicum L. The shape of basil leaves is simple and cross facing each other with pointed leaf tips and petiole length reaching 2 cm. The leaves are elliptical in shape with leaf length reaching 5 cm and leaf width reaching 2.5 cm (Ardiana D, et al, 2013). Morphology basil plants have morphological features, namely erect branched stems, 0.6-0.9 m in height, with green or sometimes purple stems and branches.…”
