Abstract

The utilization of coffee processing waste in the form of rind and fruit flesh has the potential as a natural antioxidant. Coffee rind contains several secondary metabolite compounds, one of it was the polyphenol. Phenol compounds contains antioxidant, antitumor, antiviral, and antibiotic activities. Phenol compounds are known has a role in antioxidant activity. The greater the phenolic compounds so were the antioxidant activity. The drying process in the making of coffee rind have an impact on the phenol and the antioxidant capacity. The aim of the study was to determine the effect of the drying method (oven and sunlight) towards the total phenol and antioxidant capacity of Arabica coffee rind (Coffea arabica L.). Total phenol was determined by the Follin Chiocalteau Phenol method and antioxidant capacity by the DPPH method. The results of the analysis found that the highest total phenol in the green coffee rind dried by sunlight for 20 hours is equal to 1400,652 mg GAE/100g. Drying process by sunlight was able to maintain and produce high total phenols. The antioxidant capacity of green coffee rind (by sunlight) has the highest antioxidant capacity of 6,638.61 mg GAEAC/L.

Abstract

Identification compound of simplisia extract by Thin Layer Chromatography (TLC), is one way to obtain active component in Kacapiring leaf (Gardenia jasminoides Ellis).The purpose of this research were to get the best crude e.xtract by organic solvent (ethanol, methanol, and ethyl acetate), and composition of the mobile phase to identify of the separate fractions by TLC. The separate fractions was calculated of Rf value and was scanned maximum wavelenght by spectrophotometer. The treatment was repeated three times, data colected was analysed by descriptive statistic. The result showed that the highest percent of extractive value to ethyl acetate (17.32 %) and the lowest was in ethanol (11.41 %). The best of mobile phase in ethanol crude extract was in mobile phase II (petroleum ether : acetone and 2-propanol 90 :10: 0.45) with 7 spots clearly, while methanol and ethyl acetate crude extract in mobile phase I (petroleum ether : acetone and 2-propanol 85:15:0.45), with separate respectively 8 and 9 spots. The identity average of compound showed that crude extract consist of chlorophyll a, chlorophyll b, lutein, feofitin, beta carotene, and some of spots still unknown identity. Ethyl acetate and mobile phase I were the best of solvent and mobile phase to extract and identify of Kacapiring simplisia.

Abstract

Diluent solution in microbiology analysis has a very important role in obtaining samples with the best number of microbes that can be counted from 30 to 300 colonies. Waste of air conditioner (AC) water which has not been utilized optimally has potential as a diluent solution. The purpose of this study was to determine the potential waste of AC water as an alternative diluent solution compared to some diluent solutions in the antibacterial test of Zedoary Rhizome tea against Escherichia coli (E. coli). Analysis potential of diluent solution using the plate count method, then used as a diluent solution in the anti-bacterial test of Zedoary Rhizome tea against E. coli ATCC 25922 by contact method for 24 hours and cell quantity was calculated by hemocytometer. This study used RAL with 4 treatment levels of diluent solution, namely: AC water, Pepton Water (PW 0.1%), physiological salts (0.85% NaCl) and demineralized aquades (Aq DM). The results showed that AC water thinners had a significant effect with PW and Aq DM diluents seen from the highest average E. coli cell value of 2.6 x 108 CFU/ml obtained in AC water thinners and the smallest value of 1.3 x 108 CFU/ml of Aq DM diluents. Tests of pH showed a 0.85% NaCl diluent solution of 6.95 was significantly affected by other diluent solutions. Antibacterial test showed that treat waste of AC water diluent had a significant effect with other diluents with an inhibition value of 60.81% and said to be bacteriostatic.

Abstract

Lactic acid bacteria are important microorganisms in food fermentation technology. Lactobacillus plantarum 1 RN9 is a LAB isolated from bamboo and can be used as a starter culture in making curd. During the processing of LAB culture it can be damaged so that it can eliminate its function as a probiotic. On the other hand, storing culture in a fresh condition cannot be carried out for a long time. Thus we need a preservation method (preservation) of lactic acid bacteria that can maintain its viability and superior of the properties of an isolate. Encapsulation is one way to maintain the viability of probiotics and protect probiotics from damage due to unfavorable environmental conditions such as gastric acid and bile salts (Wu et al., 2000). The purpose of this study was to determine the effect of the type of encapsulant on the yield and viability of L. plantarum 1 RN9 during the freeze drying (FD) process. The encapsulant material used was skim milk, lactose, maltodextrin with observational parameters including yield, total LAB and viability of LAB. Based on the results of the study showed that the yield of dry cultures of L. plantarum 1 RN9 ranged from 26.42% to 41.08%, which statistically showed a significant difference (P> 0.05) between treatments. The highest yield was obtained in skim milk encapsulant by 41.08% then lactose was 39.44% and maltodextrin 26.42%. The viability of L. plantarum 1 RN9 culture after freeze drying with lactose encapsulant and maltodextrin decreased by 2.3 to 2.5 log cycles but still had high viability while viability with skim milk encapculation increase. The total LAB with skim milk encapsulants increased by 1 log cycle from 10.3 log CFU/g to 11.3 log CFU/g. Based on the results of the studyit can be conclused the use of skim milk encapsulants on L. plantarum 1 RN9 gives the best results compared of lactose and matodextrin with a yield of 41.08% and viability increases 1 log cycles ie 1.6 x 1011 CFU/g.

Abstract

Diabetes mellitus is a metabolic disease characterized by high blood sugar or hyperglycemia (>=126 mg/dl). In addition to drugs and insulin injections, regulating diet is an important control factor for this disease. Diabetics with complications will experience low intake of food due to various complaints such as nausea, vomiting, and decreased appetite. These low intake if not well handled will cause malnutrition. Small but nutrient-dense food portions are needed in the treatment of diabetics with low intake cases. Instant porridge with high fiber content made from potato flour and rice bran is expected to overcome the low intake problem in diabetic patients. The purpose of this study was to determine the combination of potato flour and bran best for instant slurry making and the best formulation could have the effect of reducing blood sugar levels in diabetes mellitus. This research was conducted in 2 stages. The first stage of the study used an experimental method with a Randomized Block Design for Proximate Test, with three (3) replications. In the phase I study there were 6 formulations of instant slurry, a combination of potato flour and bran, namely: 90:10 (P1), 85:15 (P2), 80:20 (P3), 75:25 (P4), 70:30 (P5) and 65:35 (P6), which will be selected as the best product based on the proximate test results, crude fiber content and sensory test (taste, color, aroma, texture and overall acceptance). Based on the matrix point, P1 instant slurry became the best product with the highest value which was then tested for its effect on blood sugar in experimental animals (mice) for 28 days in the phase II study. The best instant pulp products have a low carbohydrate content of 48.20%, low fat of 7.21%, high protein 31.77% and crude fiber of 8.70%. There were 4 treatment groups, namely healthy mice given standard feed (1), diabetic rats given standard feed (2), diabetic rats fed standard feed energy doses: instant porridge of 50:50 (3) and diabetic rats given 100% instant porridge (4). Based on the results of variance, giving 100% instant porridge (group 4) had a very significant effect on the decrease in the mean blood sugar of mice since the first week of intervention. For four (4) weeks of intervention, rats given 100% instant porridge had an average blood sugar drop of 25.78% and were categorized normal (>=126 mg/dl).
