Abstract

This research aimed to determine the influence of citric acid concentration on characteristic ofthe pigment extract of seed jelly tamarillo waste and to determine the exact concentration of citric acidto produce the best characteristic of pigment extracts of seed jelly tamarillo waste. This research useda randomized block design with treatments concentration of citric acid concentration on five levels,such as: 2%, 4%, 6%, 8%, and 10%. The treatment was repeated 3 times in order to get 15 unitsexperimntal. Vareabel observed were the yield, moisture content, anthocyanin total, phenol total andantioxidant activity. The results showed that the treatment is very significant on yield, totalanthocyanin, and total phenols, dan significantly on water content. The best results were obtainedfrom the treatment of citric acid concentration of 10% with characteristic yield of 42.29%, watercontent of 13.23%bk, anthocyanin total of 82.38 mg/100g, and phenols total of 33976.20 mg/100g.The best results pigment extract had antioxidant activity at IC50 on concentrations of 75.15 ppm.

Abstract

The aim of this research was to know effect the ratio of pineapple and mustard greens to the characteristic of jam, and determine the best ratio made by those, to produce a good characteristic of jam. This research used Complete Random Design with the treatment comparison of pineapple and mustard green comprised of 5 (five) treatments, such as 100% pineapple : 0% mustard greens, 95% pineapple : 5% mustard greens, 90% pineapple : 10% mustard greens, 85% pineapple : 15% mustard greens, 80% pineapple : 20% mustard greens. All of treatments were repeated for 3 times to obtain 15 research units. Data were analyzed using analysis of variance and if an influences occurred among the treatments, the research would be continued to the Duncan’s test. Results of this research had showed that the comparison ratio of pineapple and mustard greens gave influences to the water content, total sugar, total calcium, total soluble solid, viscosity, pH balance, texture, color, flavour, taste and overall acceptance of a jam. The best ratio of pineapple and mustard greens showed of percentage 90% pineapple : 10% mustard greens with characteristics : 25,58% water content, 57,45% total sugar, 6.176 mg/100g calcium, 59,15%brix total soluble solids, viscosity 64580 cps, 4,65 pH, texture (very like), color (like), flavor (like), taste (very like) and overall acceptance (very like).

Abstract

The purpose of the study was to find the optimum ratio of glutinous rice flour and red kidney bean flour (Phaseolus vulgaris L.) to produce temerodok with the best characteristics. The completely randomized design (CRD) was used in the research with treatment that is the ratio of glutinous rice flour with red kidney bean flour which consists of 6 levels: 100%:0%,90%:10%, 80%:20%, 70%:30%, 60%:40%, 50%:50%. The treatment was repeated 3 times to obtain 18 units of the experiment. The data obtained were analyzed by variance and if the treatment had an effect on the observed variable then continued with the Duncan Multiple Range Test (DMRT) test.The ratio of glutinous rice flour and red kidney beans flour has a very significant effect on water content, ash content, protein content, fat content, carbohydrate content, color (scoring), texture (hedonic and scoring), taste (scoring) and significant effect against the levels of crude fiber, color (hedonic), taste (hedonic) and overall acceptance (hedonic). The ratio of glutinous red kidney bean flour (50%: 50%) produces the best characteristic temerodok based on the matrix table, namely: water content 5.49%, 2.53% ash content, 15.19% protein content, fat content 15.46%, 61.31% carbohydrate content, crude fiber content 5.54%, brown color, hard texture, taste very red beans, color, texture, taste and overall acceptancered kidney bean taste and neutral color, texture, taste and and overall acceptability.

Abstract

The purpose of this study was to determine the nutrient digestibility and antioxidant activity of mung bean sprout flour. This study was conducted using 12 hours germination and without germination of mung bean, and each treatment was repeated three times. Mung bean flour and mung bean sprouts flour were tested for moisture content, ash content, protein content, fat content, carbohydrate content, protein digestibility, starch digestibility, total phenol, and antioxidant activity. The results showed that germination of mung bean had a very significant effect on moisture content, antioxidant activity (IC50), and total phenol, a significant effect on starch digestibility, and had no significant effect on ash content, protein content, fat content, carbohydrate content, and protein digestibility. The results showed that mung bean sprout flour has a moisture content of 6.74%, ash content 3.39%, protein content 32.13%, fat content 11.33%, carbohydrate content 46.41%, protein digestibility 46.80%, starch digestibility 93.45%, total phenol 22.02 mg/100 g, and antioxidant activity (IC50) 454.50 ppm.

Abstract

This study was conducted to determine the effect of different solvents on the antioxidant activity of rice hyacinth extract and to find out the right type of solvent used to extract rice hyacinth with the highest antioxidant activity. The experimental design used in this study was a completely randomized design with various types of solvents as a treatment using maceration method. The treatment consisting of four type of solvents i.e water, ethanol, methanol, and acetone. All treatments were repeated four times to obtained 16 experimental units. The data obtained were analyzed by variance and if the treatment had significant effect then followed by Duncan test. The results showed that the various types of solvent treatments had a very significant effect (P<0.01) on antioxidant activity. The results showed that ethanol solvent had the best treatment which produced an antioxidant activity based on IC50 of 0,49 mg/mL, yield of 26.17%, total phenol content of 11.12 mg GAE/g, total flavonoid content of 8.26 mg QE/g, total tannin content of 5.18 mg TAE/g.

Abstract

Lactobacillus sp F213 (LbF213) is a lactic acid bacteria isolated from a healty infant feces, which has been proven as a probiotic bacteria because it is resistant to low pH, bile salts, digestive enzymes, able to survive and colonize the intestine, and prevent infection from E.coli pathogens.This study was conducted to know the viability of Lactobacillus sp F213 probiotic bacteria in rice juice during cold storage and its effect on the characteristics of rice juice products. This study used a descriptive method in objective tests (total lactic acid bacteria test, total glucose, pH and total acid) and a complete randomized design method in the subjective test (sensory test). This study used two treatments, namely rice juice with the addition of Lactobacillus sp F213 and without the addition of probiotic bacteria which are then tested every 3 days of 0, 3, 6, 9 and 12 in cold temperature. The test results data presented in the way form of tables and figures. The results of this study indicate that the viability of Lactobacillus sp F213 to 12 days storage at cold storage temperatures. The addition of Lactobacillus sp F213 also tends not to affect the characteristics of rice juice during storage either from the results of pH, total acid and total glucose and from sensory characteristics such as color, aroma, taste and overall acceptance. Keywords: probiotics, rice juice, viability, Lactobacillus sp F213

Abstract

This research aims to determine the effect of drying method the antioxidant capacity of wedang uwuh and to obtain the highest antioxidant capacity of wedang uwuh. This study was designed using a completely randomized design (CRD) with four parameters of drying methods there are sun-drying, air-drying, greenhouse and oven, which were repeated four times. Therewere many parameters analyzed in this research such as water content, antioxidant capacity, total phenol and sensoryincluding color, aroma, taste and overall acceptance. All data were statistically analyzed using ANOVA and continued with Duncan's (DMRT) (? = 5%). The results showed that the drying method had a significant effect on the water content, antioxidant capacity and total phenol of wedang uwuh, but did not significantly affect to the sensory results. Air-drying method produced wedang uwuh with the highest antioxidant capacity of 63,63 mgGAEAC/L, with a moisture content of 8,05 %, and total phenol of 23,70 mg/L where, based on color, taste, flavor and general acceptance the panelists rather like the wedang uwuh produced.
