Animal feed should ideally be inexpensive and not competing with humans. Ampas know is a waste of the manufacture of tofu that contains protein and high energy. Its use has problems due to the existence of antinutrient and cannot be kept long. Lactobacillus Plantarum is a lactic acid (Gram-positive) bacteria used in the fermentation process to improve the quality of feed. The goal of fermentation is to remove the anti-nutrients that exist in the tofu pulp and increase the content of Isoflavone (Daidzin, Glycitein, and Genistein) and Isoflavone is a source of antioxidants important to growth. The study uses a Completely Randomized Design with 5 treatment of microbial culture concentrations of 1%, 5%, 10%, 15%, and 20% (V/w), respectively repeated 3 times. The result of analyzes in the pulp of tofu fermentation suggests that fermentation by Lactobacillus Plantarum can increase the content of Daidzein, Glycitein, and genistein with the highest value resulting from the use of L. Plantarum 20% respectively 191.21 + 24.9 μg/g, 85.96 μg/g, and 120.82 μg/g. It can be concluded that the higher the use of the concentration of L. Plantarum in tofu pulp can increase the levels of isoflavone, so it is advisable to conduct research with the concentration of L. Plantarum higher in tofu pulp

               Natural or local yeasts are microorganisms from natural ingredients obtained from fermentation without the need for artificial additives. The objectives of the present study were 1.) to evaluate the physical quality of potato doughnuts produced from the local yeast derived from residue of red fermented palm sap, 2) to obtain the best treatment from the use of local yeast in making doughnuts. In the fermentation process, yeast converts sugar and carbohydrates in the dough into carbon dioxide gas (CO2) and alcohol. Doughnuts are made from wheat flour, but the addition of potato paste can improve the texture so that it is softer and tender due to the interaction between gelatinized starch and gluten but can reduce its swelling power.             The experiment was designed using a completely randomized design (CRD) with three treatments and five replications to produce 15 experimental units. The treatments were a) Control (commercial yeast); b) Wheat flour: potato paste: local yeast; 2:1:1; c) Wheat flour: potato paste: local yeast; 2:1:2 and d) Wheat flour: potato paste: local yeast; 2:1:3. The results showed that the best treatment formula was obtained in the treatment B (wheat flour: potato paste: local yeast; 2:1:1) with 20,6% moisture content,  2,09% protein content and 3,644 color value (very like), 3,800 taste value (very like) and texture/tenderness with a value of 1032,500.

ABSTRACT The harvest of green coffee fruits affects their quality; they should be separated from the ripe fruits during processing. The proportion of harvested green fruits can be high, requiring information and technologies to adequately manage and add value to coffee beans from this fruit category. The objective of this work was to evaluate the quality of coffee beans from green fruits separated during a wet processing and peeled after temporary immersion in water. A completely randomized design was used, consisting of six treatments (ripe peeled coffee fruits dried on suspended yards, non-peeled green coffee fruits under traditional dry management on a concrete yard, and peeled and non-peeled green coffee fruits temporarily immersed in water and dried on suspended and concrete yards) and four replications, in the 2018 crop season. Samples of coffee beans temporarily immersed in water were peeled and separated into peeled and non-peeled fractions and dried in suspended and concrete yards. The peeling yield of green coffee beans and the physical and sensorial characteristics of the processed coffee beans were evaluated. The mean peeling yield was 62% and allowed the separation of more developed green fruits, equating them to ripe peeled coffee beans regarding physical and sensorial quality.
