Abstract. The purpose of this study, to see the interaction of the effect of drying time and temperature of the carbohydrate content of carbohydrates, the interaction of the effect of coordinated time and temperature on mocaf, and the effect of time and optimal drying temperature of mocaf. The study used a factorial randomized block design with a factor of 1, namely the drying time (8 hours, 12 hours, 24 hours) and factor 2, namely the drying temperature (50°C, 70°C, 80°C). The preliminary stage of this research is soaking the cassava chips with 5% salt. The next step is making yeast fermentation mocaf with drying time and temperature treatment using a cabinet dryer. The parameters analyzed were moisture content, ash content, fat content, protein content, carbohydrate content, and color content. The results showed that the treatment of drying time of 8 hours and drying temperature of 70°C is the best treatment measured by the De Garmo test. The test results showed that the treatment had a water content of 10.08%, a protein content of 0.73%, a fat content of 0.06%, an ash content of 8.35%, carbohydrate content of 80.75%, a brightness level (L) is -11.6, the level of redness (a +) is 3.85, and the level of yellowness (b +) is 9.3. Keywords: Drying Temperature, Drying Time, Modified Cassava Flour, Yeast Tape Fermentation Abstrak.

Proses pengolahan biji kakao sangat menentukan mutu biji kakao kering yang dihasilkan. Proses fermentasi mempunyai peran yang sangat penting dalam pengolahan biji kakao yaitu pembentukan cita rasa dan aroma biji kakao yang dihasilkan. Tujuan dari penelitian ini adalah memberikan gambaran fermentasi yang ideal dan mencari wadah fermentasi yang bisa digunakan dalam skala produksi kecil dan sederhana. Penelitian ini dilakukan dengan melakukan fermentasi menggunakan dua ukuran wadah yang berbeda, yaitu kotak kayu besar dan kotak kayu kecil. Biji kakao difermentasi selama 3 hari (3x24 jam) dengan pembalikan dan pemantauan suhu setiap hari. Biji kakao hasil fermentasi dikeringkan dengan cara sun drying dan pengeringan mekanis (cocoa dryer) selama ±7 hari. Hasil penelitian menunjukkan fermentasi dengan kotak kayu besar mempunyai efektifitas lebih baik dibandingkan kotak kayu kecil. Biji kakao yang dihasilkan dari fermentasi kotak kayu kecil juga dapat terfermentasi dengan baik sehingga kotak kayu kecil dapat digunakan sebagai alternatif untuk petani yang mempunyai hasil produksi tidak banyak.
One of the interesting marine products to be explored is flying fish (Hirundichthys oxycephalus) roes. The flying fish roe is usually called tobiko. The aim of this study is to extract protein from tobiko filaments using an isoelectric point approach, analyze their chemical properties, and apply them to the nutrification of rice-corn milk. Extraction of tobiko filaments using an isoelectric point approach resulted in an optimal pH of 8.5 based on the protein content (73.52 ± 0.07 %). Extraction under alkaline conditions (pH 8.5) resulted in a protein concentrate yield of 9.04% and an insoluble portion of 69.79%. That protein concentrate showed 15 amino acid, leucin (5.86 ± 0.01%), lycin (3.69 ± 0.02%), valin (3.41 ± 0.02%), isoleucine (3.33 ± 0.01%), threonine (2.86 ± 0.01%), phenylalanine (2.30 ± 0.02%), histidine (1.38 ± 0.01%), and methionine (1.21 ± 0.01%), glutamate (7.08 ± 0.01%), arginine (6.11 ± 0.01%), alanine (3.82 ± 0.01%), aspartic acid (3.75 ± 0.01%), serine (3.05 ± 0.02%), glycine (1.84 ± 0.01%), and tyrosine (1.46 ± 0.01%). The addition of protein concentrate from tobiko filament showed an increase in protein content in rice-corn milk so the purpose of nutrification in this study was successful. The best formulation is in the composition of rice: corn: protein concentrate (15:5:3%) with details of moisture content 65.07 ± 0.02%, ash content 0.50 ± 0.01%, the lipid content 0.28 ± 0.02%, the protein content 21.18 ± 0.02 %, the carbohydrate content 12.95 ± 0.02%, with a total energy 278.13 ± 0.03 kcal.
The edible coating based on cassava starch is a method of giving a thin coating on food product to extend the shelf life have weakness has low barrier properties to moisture it’s required the addition of a stabilizer to extend the shelflife that applied on chicken meatball which has a short shelf life is 24 hours. The purpose of this research is to find different types and concentrations of stabilizers and determine the best treatment. The research nested. Extraction of carrageenan from seaweed(Eucheumma cotton) and extraction of pectin from green cincau leaf (Premma oblong folio) then make edible coating treated with a natural stabilizer (carrageenan and pectin) and synthetic (STPP and CMC) with 0.2%, 0.3%, and 0.4% concentration. The results showed that the type of stabilizer had significant effect on moisture content, ash content, color (L), and texture, while the concentration of stabilizer had no significant effect on moisture content, color (L), color (a+), color (b+), total plate count and scent organoleptic. The best treatment was stabilizer CMC0.3%.
Indonesia is a country that has a high level of biscuit consumption. This is supported by many local food commodities. Therefore, many food products have emerged that use local food ingredients, such as bread, biscuits and cakes. One effort that can be made to enrich the nutritional content of biscuits is to add soybean flour which is rich in protein and flour of red dragon fruit peel which is rich in dietary fiber. The purpose of this study was to determine the effect of the ratio of wheat flour, soybean flour and red dragon fruit peel flour to chemical and organoleptic quality of biscuits. This research used a simple randomized block design with ratio of wheat flour, soybean flour, and red dragon fruit peel flour consisting of 10 levels: P0 (100%:0%:0%), P1 (80%:10%:10%), P2 (70%:20%:10%), P3 (60%:30%:10%), P4 (75%:10%:15%), P5 (65%:20%:15%), P6 (55%:30%:15%), P7 (70%:10%:20%), P8 (60%:20%:20%), P9 (50%:30%:20%). Each level is repeated 2 times. The parameters being observed were level of protein, fat, crude fiber, water, ash, and organoleptics (aroma, taste and texture). The results showed that the proportion of wheat flour, soybean flour and red dragon fruit peel flour had a very significant effect on level of water, protein, crude fiber, and organoleptic (taste, aroma, and texture). Treatment of biscuits with proportion of wheat flour 60%: 30% soybean flour: 10% red dragon fruit peel flour was the best treatment with level of water 6,58%, ash 0,76%, fat 27,95%, protein 9,74%, crude fiber 6,10%, organoleptic of taste 4,65 (delicious), aroma (rather tasty), and texture (rather not hard)
