Abstract

Kefir goat milk is fermentation beverage produced by goat milk which had been pasteurization then continued with fermentation used cultur kefir which consist of Lactobacillus acidophilus, Streptococcus lactis and Sacaromyces cereviseae. This research ought to know influence of incubation time and kind of inoculum of quality of kefir goat milk including physical and microbiology qualities. This research factorial design (5x3) are used two way anova and friedman statystic (α=0,05). Result of this research showed that incubation time and kind of inoculums had been influence towards to the chemistry qualities are lactate acid and protein content of kefir goat milk. Incubation time had been influence toward to pH and alcohol content kefir goat milk. While kind of inoculum had not been influence toward to pH and alcohol content kefir goat milk. Incubation time 12 hours with Lactobacillus acidophilus and Streptococcus lactis to produce the best quality of kefir goat milk. Key word : Goat milk, Kefir, Lactobacillus acidophilus, Streptococcus lactis, Sacaromyces cereviseae

Abstract

The soap of mangkokan (Nothopanax Scuteliaium Merr) leaf extract is a soap made from extracts of leaves mangkokan (Nothopanax Scuteliaium Merr) with different concentration of mangkokan leaf extract, among others, 70%, 80% and 90%. The Purpose of this research to determine the effect of concentration of mangkokan soap on the physical properties and microbiology. Physical properties include pH and water content while Microbiology includes the inhibitation of the bacterium Staphylococcus aureus. Analysis in this reasearch using one way anova factorial design 1 x 3. The results obtained in this reasearch is the difference in concentration of mangkokan (Nothopanax Scuteliaium Merr) leaf extract significantly affect the pH value of the soap and the difference in concentration of mangkokan (Nothopanax Scuteliaium Merr) leaf extract there is no significant influence on the water content and the inhibition of bacterial. Keywords : Soap, Leaves Mangkokan, Staphylococcus aureus.
