Wongkar, Elisabeth (2013) Uji Efektivitas Ekstrak Etanol Daun Pecut Kuda (Stachytarpheta Jamaicensis L. (Vahl)) Sebagai Antibakteri Terhadap Escherichia Coli Secara In Vitro. Sarjana thesis, Universitas Brawijaya.
Abstract
Merupakan Bakteri Yang Paling Sering Menyebabkan Diare Dan Dilaporkan Sudah Resisten Terhadap Berbagai Antibiotik. Karena Itu Perlu Dilakukan Penelitian Untuk Mendapatkan Alternatif Terapi. Salah Satu Tanaman Yang Banyak Dimanfaatkan Secara Tradisional Dan Diduga Dapat Digunakan Sebagai Alternatif Yaitu Daun Pecut Kuda ( Stachytarpheta Jamaicensis L.(Vahl) )Dimana Daun Ini Memiliki Kandungan Aktif Alkaloid, Flavonoid, Saponin Dan Tannin Yang Berperan Sebagai Antibakteri. Tujuan Dari Penelitian Ini Untuk Mengetahui Efekantibakteri Daun Pecut Kuda Terhadap Bakteri Escherichia Coli Secara In Vitro . Untuk Menentukan Khm Digunakan Metode Dilusi Agar Sedangkan Untuk Menentukan Kbm Digunakan Metode Dilusi Tabung. Konsentrasi Ekstrak Yang Digunakan Adalah 0%, 17%, 18%, 19%, 20%, 21% Dan 22% Dengan Empat Kali Pengulangan. Analisis Data Menunjukkan Adanya Penurunan Jumlah Koloni Bakteri Escherichia Coli Yang Signifikan Seiring Dengan Peningkatan Dosis Daun Pecut Kuda ( Stachytarpheta Jamaicensis L. (Vahl)) (Pearson, P<0,05).Berdasarkan Penelitian Ini Dapat Disimpulkan Bahwa Daun Pecut Kuda ( Stachytarpheta Jamaicensis L.(Vahl)) Memiliki Efek Antibakteri Terhadap Bakteri Escherichia Coli Dengan Khm (Kadar Hambat Minimal)Pada Konsentrasi 20% Dan Kbm (Kadar Bunuh Minimal)Pada Konsentrasi 22%.
English Abstract
Eschericia Coli is The Most Common Bacteria That Causes Diarrhea Andits Resistant To Varies Kinds Of Antibiotics Has Been Reported. Therefore, Research To Obtain Alternative Therapy Needs To Be Done. One Of The Plants That Is Most Used Traditionally And Has Been Estimated As An Alternative Therapy Is The Blue Potterweed Leaves Which Contains Active Substances Like Alkaloid, Flavonoid Saponin, And Tannin That Has An Antibacterial Effect. This Study Aims To Determin e The Effective Antibacterial Dose Of The Bluepotterweed Leaves Against E scherichia Coli In Vitro . Agar Dilution Test Was Used To Determine The Mic Value While Tube Dilution Method Was Used To Determine The Mbc Value . Consentration Of The Ethanol Extract Used Were 0 % , 17 % , 18 % , 19 % , 20 % , 21 % And 22 % With Four Repetitions. Data Analysis Shows There Is A Significant Decrease On The Amount Of Escherichia Coli Colonies With Increasing Dose Of Ethanol Extract Of Blue Porterweed Leaves ( Stachytarpheta Jamaicensis L. (Vahl)) (Pearson, P< 0,05). Based On This Study It Can Be Concluded That The Ethanol Extract Of Blue Porterweed Leaves ( Stachytarpheta Jamaicensis L. (Vahl )) Has An Antibacterial Effect Against Escherichia Coli Bacteria With Mic (Minimum Inhibitory Concentration) Of 20% And Mbc (Minimum Bactericidal Concentration) Of 22 %.
