Abstract

Cassava is tropical plants, productive and easily cultivated so it is expected to be one of the solutions to improve Indonesia's national food security. Mocaf is fermented cassava flour products using microorganisms. Mocaf is expected to replace the use of wheat flour which its necessity is escalated through the ages, while the area of wheat as a raw material is not fitted the climate of Indonesia. This research performed some sort of branded food yeast for producing Mocaf, taken for instance Fermipan, Saf-Instant yeast, tempe raprima yeast, tapai yeast, and unbranded bread yeast. It also would be analyzed the effect of soaking cassava with salt before fermentation, to nutrients generated by Mocaf. The objective of this research was knowing the types of yeast and fermentation process that is best in improving the nutritional quality of Mocaf. The best produced Mocaf in this research was made from fermented Mocaf using tapai yeast which was soaked with salt. It produced the highest level of protein i.e 40.860%, with low water levels i.e 6.640 %.

Abstract

This research was aimed at studying the activities of amylase produced by isolate bacteria which were isolated from hot water resource, Ciseeng Bogor. Four among the nine isolate bacteria grown on NA media showed the activities of amylase. The character of Amylase was analyzed in 2 isolates, A1 and A3. Isolate A1 was optimally active at pH 3, 55 C, meanwhile isolate A3 was optimally active at pH 4, 50 C. The amylase resulted from either isolate A1 or isolate A3 was acid amylase. Both of the isolates were relatively stable at pH acid, whereas the amylase resulted from A3 was not stable on pemanasan in 30 minutes, and the amylase from A1 increased after being incubated at more than 60 C in 30 minutes. In conclusion, isolate A1 identified as Bacillus Coagulans indicated the optimal activities when it was grown at pH 6 and at the 14th hour of incubation.Key words: amylase, isolation, enzyme
