Tujuan dari penelitian ini adalah untuk mengetahui kualitas mikrobiologi air sumur di sekitar kandang kelompok sapi potong di Yogyakarta. Telah dikumpulkan sebanyak 12 contoh air sumur di sekitar kandang kelompok sapi potong dari Kabupaten Sleman, Kulon Progo, dan Bantul. Contoh air sumur diperiksa terhadap Coliform dan E. coli dengan metode most probable number (MPN), sedangkan Salmonella sp. dengan isolasi dan identifikasi dengan metode Andrews & Hammack. Sebanyak 91,6% dari 12 contoh air sumur, jumlah Coliform dan E. coli melebihi ambang batas baku mutu air rumah tangga. Salmonella sp. berhasil diisolasi dari air sumur di sekitar kandang sapi potong Kabupaten Kulon Progo.

A total of 12 well water samples were collected from around beef cattle farms in Sleman, Kulon Progo, and Bantul district. These samples were analyzed for Coliform and E. coli by using most probable number (MPN), where as Salmonella sp. with isolation and identification by Andrews & Hammack methods. A total 91.6% of 12 well water samples have Coliform and E. coli that exceeds the threshold household water quality standards. Salmonella sp. was isolated from well water around beef cattle farm in Kulon Progo district.
