Abstrak. Tujuan penelitian ini adalah untuk melihat pengaruh jenis rempah, konsentrasi rempah, dan interaksi jenis rempah dan konsentrasi rempah terhadap kualitas yoghurt susu kambing. Penelitian menggunakan Rancangan Acak Lengkap (RAL) Faktorial dengan 2 faktor. Faktor pertama adalah jenis ekstrak rempah (R) yaitu R1 = kayu manis dan R2 = pala. Faktor kedua adalah konsentrasi ekstrak rempah (K) yaitu K1 = 2% dan K2 = 4% dan K3 = 6%. Hasil penelitian menunjukkan ekstrak rempah (R) berpengaruh sangat nyata (P ≤ 0,01) terhadap aroma dan total asam, tetapi tidak berpengaruh terhadap rasa, warna, tekstur, total bakteri asam laktat, pH, viskositas, dan kadar protein. Konsentrasi rempah (K) berpengaruh nyata (P≤0,05) terhadap rasa dan viskositas, tetapi tidak berpengaruh terhadap warna, tekstur, pH, total asam, total bakteri asam laktat, dan kadar protein. Interaksi jenis ekstrak rempah dengan konsentrasi ekstrak rempah berpengaruh nyata (P≤0,05) terhadap kadar protein dan total bakteri asam laktat tetapi tidak berpengaruh terhadap total asam laktat, dan pH. Abstract. The purpose of this study was to determine the effects of type and concentration of spiceson the quality of goat milk yogurt. The study used a Complete Randomised Design (CRD) Factorial with 2 factors. The first factor was the type of spice extract (R) that was R1 = cinnamon, and R2 = nutmeg. The second factor was the concentration of spice extract (K) that was K1 = 2%, K2 = 4%, and K3 = 6%. The result showed that the spice extract obviously affected (P ≤ 0.01) on the aroma and acid total, but it did not effect on the taste, color, texture, total of lactic acid bacteria, pH, viscosity, and protein. The spice concentration (K) obviously affected (P≤0.05) to the taste and viscosity, but it did not effect on the color, texture, pH, acid total, total of lactic acid bacteria, and protein. The interaction type of spice extract with the concentration of spice extract obviously affected (P≤0.05) on the protein content and total of lactic acid bacteria, but it did not effect on lactic acid total, and pH.
