Abstract

Palm sugar yogurt is a product of fermented milk with palm sugar in the form of a thick to semi-solid liquid with a specific sour taste. The making of this yogurt utilizes palm sugar to help form a texture and give a sweet taste to yogurt, which is acidic. This research aims to determine the effect of adding palm sugar sweeteners to protein and fat levels in yogurt, to study the activity of starter bacteria Lactobacillus bulgaricus and Streptococcus thermophiles in various concentrations, as well as knowing the functional value of low-fat yogurt with high nutrients that are good for health. This research method consists of 3 stages: preparation of raw materials, making palm sugar yogurt, and incubation (fermentation). The study used a completely randomized design with one factorial, namely with the breakdown of fixed variables with the addition of palm sugar (5% w/v) and lactic acid bacteria (Lactobacillus bulgaricus and Streptococcus thermophiles) and independent variables with the addition of the number of starters (2.5% and 5% v/v) with an incubation time of 8 and 10 h. The results showed that the highest protein content was obtained in the B1D treatment, which was 4.17%. Meanwhile, based on the fat analysis, the best results obtained were the lowest levels in the A2C treatment, having a test content of 1.89%.
