Tujuan penelitian ini adalah mengetahui pengaruh penambahan bunga telang dengan persentase berbeda terhadap warna dan titrable acidity yogurt susu kambing. Materi yang digunakan adalah 7,5 liter susu kambing dan 16 gram bunga telang kering. Metode penelitian yang digunakan adalah metode eksperimen. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 kali ulangan. Perlakuan yang diuji terdiri dari: P0 (tanpa penambahan bunga telang), P1 (penambahan bunga telang 1%), P2 (penambahan bunga telang 3%) dan P3 (penambahan bunga telang 5%). Peubah yang diukur adalah warna dan titrable acididy yogurt susu kambing. Hasil analisis variansi menunjukkan bahwa penambahan bunga telang dengan persentase berbeda berpengaruh sangat nyata (P<0,01) terhadap warna dan titrable acidity yogurt susu kambing. Uji lanjut Beda Nyata Jujur (BNJ) menunjukkan bahwa antar perlakuan berbeda sangat nyata (P<0,01). Bunga telang dapat dijadikan sebagai pewarna alami yogurt susu kambing hingga 5% memberikan warna ungu kebiruan yang lebih pekat. Penambahan bunga telang 1% dalam pembuatan yogurt susu kambing menghasilkan nilai titrable acidity yang sesuai Standar Nasional Indonesia.

The purpose of this research was to find out the effect of adding telang flowers on color and titrable acidity of goat milk yogurt. The materials used 7.5 liters of goat milk and 16 grams of dried telang flowers. The method of this research used experimental method. The design of this research was used Completely Randomized Design (CRD) that consisted of 4 treatment and each treatment was repeated five times. The treatments were: P0 (without adding telang flowers), P1 (addition of telang flowers 1%), P2 (addition of telang flowers 3%) and P3 (addition telang flowers 5%). The variables observed were color and titrable acididy of goat milk yogurt. Analysis of variance showed that the addition of telang flowers was very significant effect (P<0.01) on the color and titrable acidity of goat milk yogurt. Further test of Honest Significant Difference (HSD) showed that all of treatment was very significant effect (P<0.01) on color and titrable acidity of goat milk yogurt. From this research, telang flowers can be used as a natural dyes with 5% of goat milk yogurt have a purplish blue more than control. Adding telang flowers 1% of goat milk yogurt have a resulted titrable acidity as Indonesian National Standard.
