Abstract

ABSTRAK Streptococcus mutans merupakan salah satu bakteri penyebab karies gigi. Penggunaan antibiotic merupakan terapi infeksi yang umum dilakukan untuk menghambat pertumbuhan bakteri. Biji anggur diketahui mengandung senyawa polifenol yang berpotensi sebagai antibakteri. Tujuan penelitian ini untuk mengetahui aktivitas ektrak biji anggur terhadap Streptococcus mutans. Bahan uji yang digunakan adalah buah anggur yang diambil bijinya. Buah anggur diperoleh dari Pasar Induk, Kramat Jati, Jakarta Timur. Ekstrak biji anggur diperoleh dengan metode maserasi menggunakan pelarut etil asetat dan etanol 70%. Uji aktivitas antibakteri dilakukan menggunakan metode difusi cakram pada media Mueller Hinton Agar dengan konsentrasi 5%, 10%, 20%, dan 40%. Hasil penelitian menunjukkan bahwa ekstrak etanol 70% biji anggur memiliki aktivitas antibakteri pada konsentrasi 5%, 10%, 20%, dan 40% dengan nilai hambatan secara berurutan sebesar 8,46 mm; 8,91 mm; 9,89 mm; dan 11,04 mm. Hasil pada ekstrak etil asetat juga menunjukkan ada aktivitas penghambatan pada konsentrasi 5%, 10%, 20%, dan 40% dengan nilai hambatan secara berurutan sebesar 7,72 mm; 8,50 mm; 9,64 mm; dan 10,51 mm. Ekstrak etanol 70% biji anggur memiliki daya hambat yang lebih besar dibandingkan dengan ekstrak etil asetat. Hasil ini dapat menjadi acuan untuk pengembangan potensi biji anggur sebagai bahan obat atau kosmedik (kosmetik-medik) penanganan karies gigi. ABSTRACT Streptococcus mutans is one of the bacteria that cause dental caries. The antibiotics usually used for the therapy of this infection to inhibit bacterial growth. Polyphenol, which recommended as an antibacterial agent, is common secondary metabolites in grape seeds. The purpose of this study is to know the activity of grape seed extract against Streptococcus mutans. The grape seeds were obtained from fresh fruits which bought from Pasar Induk, Kramat Jati, East Jakarta. The grape seed extract was obtained by the maceration method using ethyl acetate and 70% ethanol. The antibacterial activity test was carried out using the disk diffusion method on Mueller Hinton Agar media with a concentration of 5%, 10%, 20%, and 40%. The results showed that 70% ethanol extract of grape seeds had antibacterial activity at concentrations of 5%, 10%, 20%, and 40% with a value of 8.46 mm; 8.91 mm; 9.89 mm; and 11.04 mm respectively. The results of ethyl acetate extract also showed inhibitory activity at concentrations of 5%, 10%, 20%, and 40% with values ​​of 7.72 mm; 8.50 mm; 9.64 mm; and 10.51 mm respectively. The inhibition of 70% ethanol extract of grape seed is greater than ethyl acetate extract. The results of the study can be used as reference for the potential development of grape seed as a medicinal or cosmedic cosmetic-medical) ingredient for treating dental caries.

Abstract

Sempur (Dillenia suffruticosa) leaves are known as a traditional medicine for the people of Bangka-Belitung Island. The local people empirically utilize the boiled water of D. suffruticosa leaves as anti-diarrhea. However, the antimicrobial activity of the ethanol extract of D. suffruticosa leaves has not been reported. This study aims to determine the antimicrobial activity of the ethanol extract of D. suffruticosa leaves against several microorganisms: Staphylococcus aureus as Gram-positive bacteria, Escherichia coli as Gram-negative bacteria, and Candida albicans as fungi. Extraction was carried out by maceration method with 70% ethanol, then screened for phytochemical constituents. The antimicrobial test was carried out by the disc diffusion method using Nutrient Agar (NA) for bacteria, and Sabouraud Dextrose Agar (SDA) for fungi. The results of phytochemical screening showed that the ethanol extract of D. suffruticosa leaves contained alkaloids, flavonoids, tannins, and saponins. The antimicrobial test showed that the extract of D. suffruticosa leaves could inhibit the growth of S. aureus at concentrations of 10%, 20%, and 40% were 8.35±0.05; 9.34±0.32; and 10.52±0.22, respectively. The ethanol extract of D. suffruticosa leaves could inhibit the growth of S. aureus, whereas E. coli and C. albicans did not show any activity.
