hours, 16 hours, 20 hours.
The results showed that the best treatment was the concentration
4% starter and fermentation time of 20 hours which produces yogurt with levels
soluble protein 2.449%, 0.565% total acid, pH 4.5, and total BAL 7.65 log cfu / ml.
Hedonic test results showed a total of 135.5 ranking sense (love-love), texture
12 (love-love), and the aroma 120.5 (love-love).
Results of financial analysis values ??obtained Brake Event Point (BEP) of 42.5
%, with a capacity of 8287.5 liters / year, Pay Back Period (PP) of the company 2.4 years,
Cost benefit ratio of 1.145, NPV Rp. 69,980,040, - and IRR of 24.42%.
