Bastian, Karina Akilah and Dr. dr. Dwi Yuni Nur Hidayati, M.Kes, Sp.MK and Ningrum Paramita Sari, S.Keb.Bd, M.Biomed (2022) Uji Efek Antimikroba Ekstrak Etanol Teh Hijau (Camellia sinensis L.) Terhadap Streptococcus agalactiae Secara In Vitro. Sarjana thesis, Universitas Brawijaya.

Abstract

Latar Belakang: Sebanyak 65% infeksi yang terjadi pada ibu hamil adalah akibat dari ketuban pecah dini (KPD). Ketuban Pecah Dini (KPD) merupakan salah satu penyebab utama infeksi yang terjadi pada ibu hamil. Mikroorganisme yang sering dikaitkan dengan kejadian infeksi dan ketuban pecah dini adalah Streptococcus agalactiae. Teh ihijau i(Camellia isinensis iL.) imerupakan itanaman iyang iberpotensi isebagai iantimikroba. Tujuan: Membuktikan efektivitas ekstrak etanol teh hijau (Camellia sinensis L.) mempunyai efek antibakteri terhadap Streptococcus agalactiae secara in vitro. Metode: Penelitian iini imerupakan ipenelitian ieksperimental ilaboratorik i(experiment-posttest ionly icontrol igroup idesign). Penelitian ini dilakukan dengan menggunakan metode difusi sumuran yang bertujuan untuk menentukan zona hambat yang terbentuk di sekitar lubang sumuran. Ekstraksi teh hijau diproses menggunakan metode maserasi dengan pelarut etanol 96%. Kesimpulan: Ekstrak etanol teh hijau (Camellia sinensis L.) terbukti memiliki efek antibakteri terhadap pertumbuhan Streptococcus agalactiae secara in vitro pada konsentrasi 10%, 20%, 30%, 40% dan 50%.

English Abstract

Background: Arround 65% of infections that occur in pregnant women are the result of premature irupture iof imembranes i(PROM). iPremature irupture iof imembranes i(PROM) is one of the main causes of infection that occurs in pregnant women. The microorganism that is often associated with infection and premature rupture of membranes is Streptococcus agalactiae. Green tea (Camellia sinensis L.) is a plant that has potential as an antimicrobial. Objective: To prove the effectiveness of ethanolic extract of green tea (Camellia sinensis L.) to have antibacterial effect against Streptococcus agalactiae in vitro. Methods: iThis istudy iis ian iexperimental ilaboratory istudy i(experiment-posttest ionly icontrol igroup idesign). This research was conducted using the well diffusion method which aims to determine the inhibition zone formed around the wellbore. Green tea extraction was processed using the maceration method with 96% ethanol as solvent. Conclusion: The ethanolic extract of green tea (Camellia sinensis L.) was proven to have an antibacterial effect on the growth of Streptococcus agalactiae in vitro at concentrations of 10%, 20%, 30%, 40% and 50%.
