Abstract

Brown rice has physical and sensory characteristics that are less favorable despite its high content of nutrition and phytochemical. The germination process is one way to improve and increase the acceptance of brown rice. The objective research was to determine germination time and varieties of brown rice on the physical and chemical characteristics of germinated brown rice. The research was conducted in RAL with 2 factors, germination time (24, 48, and 72 hours) and rice varieties (Mentik susu, Ciherang, and Pandan wangi). The data obtained were processed with analysis of variance to determine the effect of treatment on the parameters tested. If the effect is significant, then to determine the difference between treatments, a Tukey test is performed. Germination time of 24, 48, and 72 hours affected the color, germination, weight, dimensions of lenght, width, and thickness, bulk density, hydration capacity and swelling of germinated brown rice var. Mentik susu, Ciherang, and Pandan wangi. Germination time of 24, 48, 72 hours affected the chemical composition of BCG var. Mentik susu, Ciherang, and Pandan wangi. Based on observations of the physical and chemical characteristics of BCG var. Mentik susu, Ciherang, and Pandan wangi, germination time of 48 hours is recommended to do the germination with germination time of 48 hours compared to germination time of 24 and 72 hours.

Abstract

Synbiotics is a combination of prebiotics and probiotics that are believed to have a synergistic effect not only by inhibiting the growth of pathogenic bacteria and enhancing the growth of beneficial organisms, but also play a role as functional foods. This study was conducted to evaluate the konjac glucomannan hydrolyzate in synbiotics fermented milk. Factorial Randomized Block Design (RAK) was applied in this experiment. The combination of konjac glucomannan hydrolyzate (0%, 0.5%, 1%, 1.5%) and storage time (0 day, 30 days, 60 days) were applied to measure the acidity (pH), lactic acid konsentration and viscosity. Meanwhile viability of lactic acid bacteria and antibacterial activity were measure . The result showed that konjac glucomannan hydrolyzate supplementation were decreased product acidity (pH) and viscosity, but increased the lactic acid concentration during 60 days storage. Viability of lactic acid bacteria during 60 days storage were decreased except for 1% and 1.5% concentration. The synbiotic product showed antagonistic activity against pathogenic bacteria i.e. E. coli ATCC 25922, S. aureus ATCC 25923, and S. Typhimurium ATCC 14028. Supplementation of 1% glucomannan hydrolyzate for 60 days at 5oC showed the best characteristics in synbiotic product namely 3.45 acidity (pH), 1.24% total lactic acid , 3.24 Cp viscosity, and 8.69 log CFU/g total lactic acid bacteria.

Abstract

Red ginger is a biopharmaceutical plant that is used as herbal medicine. The use of red ginger in the food industry is mainly in an emulsion form, but that is unstable and hydrophobic. The ultrasonication technique could change the emulsion into a nanoemulsion to minimize these disadvantages. This research aimed to determine the effect of ultrasonication on red ginger oleoresin nanoemulsion characteristics. The study used a completely randomized design of 4 treatments based on sonication time (0, 30, 60, and 90 minutes). The study was analyzed by ANOVA Tukey's test at P ≤ 0.05, it showed that ultrasonication affected the characteristics of red ginger oleoresin nanoemulsion. The best result shows that in 90 minutes mixed time with transparent yellow colour. It is soluble in acetone, methanol, ethanol, and aquadest solvents. The best particle size is 572.43±8.72 nm, and antioxidant activity is (IC50) 16.34 ±1.33 ppm.©2022 JNSMR UIN Walisongo. All rights reserved.

Abstract

  Organic rice farming is a cultivation activity that is synonymous with labor-intensive activities. The use of internal inputs in organic rice farming requires time and effort to prepare. Organic farming is a low-cost farming activity because the use of internal inputs makes organic rice farming more profitable. The purpose of this study was to analyze the level of allocative and economic efficiency of organic rice farming in Lampung Province. Economic and allocative efficiency analysis is carried out by deriving the dual frontier cost function from the Cobb-Douglas Stochastic Frontier production function. The results showed that organic rice farming in Lampung Province was not allocatively efficient. Farmers have not maximized the use of organic seeds and pesticides, where both production factors have a low price allocation. Organic rice farming in Lampung Province is not yet economically efficient. Farmers have not received the maximum revenue from organic rice farming. Most of the organic rice harvested is consumed by farming families, so not all organic rice harvested generates income.
