      Abstract
      Goat milk contains better nutrient than cow's milk, but it has smell prengus so disliked by people. Processing of goat milk into yogurt can eliminate odors prengus and can improve the nutritional content of milk. Roselle flower (Hibiscus sabdariffa L) is rich in antioxidants. The addition of roselle flower extract in yoghurt is expected to improve human health. The purpose of this research is to study the chemical and microbiological characteristics of probiotic yoghurt made from fresh goat's milk with the addition of rosella flower extracts. The results showed that the addition of roselle flower extracts did not significantly affect the chemical characteristics of yoghurt seen from pH values, TAT, moisture content, protein content, ash content, and fat content but significantly different in the amount of lactic acid bacteria in the product (P<0.01).
       
      Susu kambing mengandung nutrisi yang lebih tinggi dibandingkan susu sapi, akan tetapi memiliki bau prengus sehingga kurang diminati oleh masyarakat. Pengolahan susu kambing menjadi yoghurt dapat menghilangkan bau prengus dan dapat meningkatkan kandungan nutrisi susu. Bunga rosella (Hibiscus sabdariffa L) kaya antioksidan. Penambahan ekstrak bunga rosella pada yoghurt akan memberikan rasa asam yang menyegarkan, aroma yang wangi serta dapat meningkatkan kesehatan manusia. Tujuan penelitian ini adalah mempelajari karakteristik kimia dan mikrobiologi yoghurt probiotik berbahan dasar susu kambing segar dengan penambahan ekstrak bunga rosella. Yoghurt probiotik dengan penambahan ekstrak bunga rosella sebesar 0.5% dan 1% masing-masing diamati karakteristik kimia dan mikrobiologi. Hasil analisis menunjukkan bahwa penambahan ekstrak bunga rosella tidak berpengaruh nyata terhadap karakteristik kimia yoghurt dilihat dari nilai pH, TAT, kadar air, kadar protein, kadar abu, dan kadar lemak, akan tetapi berbeda sangat nyata pada jumlah bakteri asam laktat pada produk (P<0.01).
