Gembili is one variety of local tubers originating in Indonesia, where its utilization is not in its most use. This tuber has bioactive compounds such as dioscorin, diosgenin, inulin and water-soluble polysaccharides that function as immunomodulators, including those which prevents metabolic diseases such as hyperglycaemia. The addition of gembili tubers in fermented milk has more value and is an alternative nutraceutical food for people who need a healthy diet because it contains probiotics and bioactive components. This study aims to determine the antihyperglycemic activity of fermented milk enriched with gembili flour in animal models. Probiotics contained in fermented milk are Lactobacillus acidophilus, Lactobacillus plantarum and Streptococcus thermophilus. The experimental animals used in this study are healthy male white rats, not deformed, and had never been used in previous experiments. The animals in experiment were grouped into five treatment groups namely P1=negative control, P2=positive control, P3=1 ml/rat/day of fermented milk with the addition of gembili tubers, P4=2 ml/rat/day of fermented milk with the addition of gembili tubers, and P5=3 ml/rat/day of fermented milk with the addition of gembili tubers (P5). The results of this study prove that the addition of fermented milk enriched with gembili showed significant results (p<0.05) on the decrease in blood sugar levels with the highest decrease of 43.59% in the P5 group.

Smart Academic is an information system used by administrative staff to manage administrative activities from upstream to downstream related to academia starting from the pre-lecture process such as Her-Registration of new students, filling in Study Plan Cards, and class division during the lecture process such as semester exams as well as the assessment process of each course, then proceed with administrative processing for the graduation until the graduation process, so that Smart Academic becomes a critical information system for the University if a failure occurs, it will hamper the lecture process which means the system cannot fulfill its objectives. This study evaluates the Smart Academic Information System through user experience with 8 respondents using the Usability Testing approach. This study examines user experience based on the Nielsen Heuristic method, namely

Edible film is potentially applied to replace non-biodegradable packaging for animal products, e.g. meat and meat products. The overall objective of this study was to observe the effect of different addition levels of modified casein hydrolysate (casein-catechin complexes) on mechanical (film thickness, water vapor permeability, tensile strength, elasticity), chemical (moisture content, water activity, and solubility) and microstructure properties of composite edible casein film. The edible films were formulated according to different combinations of modified casein hydrolysate and casein film solution (0.50:0.25, 0.50:0.50, 0.75:0.25, and 0.75:0.50) and compared with control (without addition of modified casein). No significant effects of the treatment were found on film thickness, water vapor permeability, tensile strength, elasticity, moisture content, water activity, and solubility of the composite edible film. However, the micrographs show that the amount of polymer was higher as the proportion of catechin was increased. In conclusion, the addition of catechin-added casein (modified casein) to casein edible film solution at up to 0.5% did not alter the mechanical properties, moisture content, water activity and solubility of the composite edible film.
