Daging Segar, Bacillus sp, Staphylococcus spAbstract
Daging merupakan salah satu produk makanan yang bernilai gizi tinggi. Umumnya daging segar juga mudah rusak seiring dengan berjalannya waktu berjualan para perdagang. Tujuannya untuk mengetahui jenis mikroorganisme yang tumbuh pada daging dan juga laju dari pertumbuhan mikroorganisme tersebut pada daging. Metoda Analisa yang digunakan adalah jenis Identifikasi Mikroorganisme dan juga laju pertumbuhan mikrobia pathogen. Serta Analisa statistika menggunakan geometric mean. Berdasarkan hasil uji identifikasi mikrobia pathogen maka di dapatkan 2 jenis bakteri yaitu Bacillus. Sp dan Staphylococcus sp. Dimana morfologi bacillus dalam media selektif. Hal ini terlihat dari bentuk koloni yang besar-besar, koloninya menyebar atau dalam bentuk rantai, serta terbentuknya hemolisis pada beberapa spesies bacillus dalam media Blood Agar Plate. Sedangkan Staphylococcus sp di tandai dengan terbentuknya warna reddish-purple pada media tersebut yang menunjukkan karakteristik dari warna staphylococcus. Jadi dapat disimpulkan bahwa Bacillus sp dan Staphylococcus sp umumnya hidup pada daging segar yang berada di suhu ruang. Sebaiknya daging segar disimpan pada suhu freezer agar tidak mudah rusak oleh bakteri patogen.
