Abstract

Manfaat dari susu kambing antara lain dapat mengobati asma, asam urat, kolesterol, dan tuberculosis karena susu kambing memiliki kandungan Flourin 10-100 kali lebih besar dari susu sapi. Susu Kambing Etawa juga memiliki fungsi sebagai Antibakteri. Oleh karena itu penulis tertarik untuk melakukan penelitian yang bertujuan untuk mengetahui aktivitas Antibakteri yang dimiliki oleh Susu Kambing Etawa terhadap pertumbuhan bakteri yang menjadi penyebab gangguan pencernaan manusia khususnya Escherichia coli. Penelitian ini menggunakan metode eksperimental laboratoris. Penelitian dilakukan di Laboratorium Mikrobiologi FK UKI dari bulan Oktober sampai November 2018. Populasi dalam penelitian ini adalah semua susu kambing etawa. Sampel yang diambil adalah susu kambing etawa dari peternakan kambing di Pondok Rangon dan Sukabumi. Hasil penelitian menunjukkan bahwa susu kambing etawa pada konsentrasi 60% dan 80% memiliki respon hambatan pertumbuhan bakteri resisten, sedangkan konsentrasi 100% memiliki respon hambatan pertumbuhan bakteri sedang, dan kontrol positif memiliki respon hambatan pertumbuhan bakteri kuat. Terdapat perbedaan bermakna (signifikan) respon hambatan pertumbuhan bakteri Eschericia coli antara susu kambing etawa konsentrasi 60%, 80%, 100% dan kontrol yang ditunjukkan dengan nilai Sig. 0,012 lebih kecil dari 0,05. Respon hambatan pertumbuhan bakteri perlakuan kontrol positif berbeda bermakna (signifikan) dengan semua perlakuan (konsentrasi 60%, 80%, dan 100%) yang ditunjukkan dengan nilai Sig. lebih kecil dari 0,05. Tidak terdapat perbedaan bermakna respon hambatan pertumbuhan bakteri antar perlakuan susu kambing etawa konsentrasi 60%, 80%, dan 100% yang ditunjukkan dengan nilai Sig. lebih besar dari 0,05. Kata kunci : aktivitas antibakteri, susu kambing etawa, Escherichia coli Benefits of goat's milk include treating asthma, gout, cholesterol, and tuberculosis because goat milk has a Flourin content of 10-100 times greater than cow's milk. Etawa Goat Milk also functions as an Antibacterial. Therefore the authors are interested in conducting research that aims to determine the Antibacterial activity possessed by Etawa Goat Milk on the growth of bacteria that are the cause of human digestive disorders, especially Escherichia coli. This study uses a laboratory experimental method. The study was conducted at the FK UKI Microbiology Laboratory from October to November 2018. The population in this study were all etawa goat milk. The samples taken were etawa goat milk from goat farms in Pondok Rangon and Sukabumi. The results showed that etawa goat milk at a concentration of 60% and 80% had a resistance response to the growth of resistant bacteria, while a 100% concentration had a response to moderate bacterial growth resistance, and positive control had a response to resistance to strong bacterial growth. There was a significant (significant) difference in response to the inhibition of growth of Escherichia coli bacteria between etawa goat milk concentrations of 60%, 80%, 100% and controls indicated by the value of Sig. 0.012 smaller than 0.05. Response to bacterial growth inhibition of positive control treatment was significantly different (significant) with all treatments (concentrations of 60%, 80%, and 100%) as indicated by the Sig. smaller than 0.05. There was no significant difference in response to inhibition of bacterial growth between the treatment of etawa goat milk concentration of 60%, 80%, and 100% as indicated by the value of Sig. greater than 0.05. Key words : The activity of antibacterial, Etawa goat milk, Escherichia coli
