Abstract

This study aims to determine the effect of processing methods on antioxidant activity and characteristics of matoa leaf herbal tea (Pometia pinnata) as well as to obtain the right processing method which produces matoa leaf herbal tea (Pometia pinnata) with the antioxidant activity and the best characteristics. The design used in this study was a Completely Randomized Design with the treatment of method processing consisting of 4 levels, method A (oven drying), method B (steaming and oven drying), method C (withening and roasting), and method D (steaming and roasting). This study was repeated 4 times to obtain 16 trial units. The data obtained were analyzed by analysis of variance and if the treatment had a significant effect it was followed by Duncan's test. The results showed that the processing method significantly affected the water content, crude fiber content, extract content in water, total flavonoids, total phenols, antioxidant activity, IC50, the sensory characteristics include color, aroma, taste and overall acceptance, and color objectively, but the treatment method has no significant effect on the ash content. The matoa leaf herbal tea with method A (oven drying) had the highest antioxidant activity and the best sensory characteristics with a water content of 8.46%, ash content of 4.64%, crude fiber content of 53.17%, extract content in water 5.25%, total flavonoids 0.87mgQE/g, total phenols 17.35mgGAE/g, antioxidant activity 87.50%, IC50 57.94ppm and color determination l, a, b (18.33: 12.02: 10.48) as well as yellowish color sensory characteristics, very typical aroma of matoa leaf herbal tea, taste rather bitter, and overall acceptance likes.

This study aims to determine the effect of boiling time to the characteristics of loloh don piduh (Centella asiatica L.) and the appropriate boiling time to produce loloh don piduh with the best characteristics. The experimental design used was a complete randomized design with 6 treatment levels: T1 (25 minutes), T2 (40 minutes), T3 (55 minutes), T4 (70 minutes), T5 (85 minutes) and T6 (100 minutes). The treatment was repeated 3 times to obtain 18 units of experiment. The data obtained were analyzed by variance and if the treatment had an effect on the observed variable then continued with Duncan test. The boiling time had a very significant effect on antioxidant activity, vitamin C levels, and the level of panelist preferences for taste and overall acceptance of loloh don piduh. Boiling time had a significant effect on total soluble solids (TSS) of loloh don piduh. Boiling time had no significantly affect on panelist preferences for the color and flavor of loloh don piduh. 25 minutes boiling time had produced loloh don piduh with the best characteristics of: antioxidant activity 90,82%, vitamin C levels 0,11%, total soluble solids (TSS) of 2o brix, panelist preferences for color, flavor, taste, and overall acceptance was preferred.

Abstract

The research aimed to determine the effect of drying temperature and time on antioxidant activity and sensory properties of herbal tea bag of grape skin and to obtain the best of temperature and drying time that can produce grape skin herbal tea bag with highest antioxidant activity and the best sensory properties.This research used a completely randomized design with factorial pattern in two factors namely, drying temperature (50oC, 60oC, 70oC) and drying time (3.0 hours, 3.5 hours, 4.0 hours). There are 9 treatment combinatioms, each treatment combination was repeated 2 times so that it obtained 18 experimental units. Parameters observed were water content, total phenols, total falvonoids, antiokxidant activity, total anthocyanin, and sensory properties. The data obtained were analyzed by analysis of variance. If the treatment had a significant effect, it would be followed by the Duncan Multiple Range Test. The results showed that interaction beetwen drying temperature and time treatment had a significant (P<0.01) on antioxidant activity, total phenols, total falvonoids, total anthocyanin, extract content in water, water content, and color (scoring test), but no significant (P>0.05) on the color (hedonic test), aroma (hedonic test), taste (hedonic test), and overall acceptance. The results showed a drying temperature of 60oC with a drying time of 3.0 hour was the optimum drying temperature and time to produce herbal tea bag of grape skin with antioxydant activity of (IC50 1512.17 ppm), water content of 5.60%, total phenol content 9.21 mg GAE/g, total flavonoids content of 6.15 mg QE/g, total anthocyanin content 8.39 mg/g, extract content 41.85%, dark purple color with hedonic color, taste, aroma and overall acceptance is neither like nor dislike.

Abstract

A survey of financial management practices by Graham and Harvey (2001) found that financial flexibility is the most important determinant of capital structure, and asset maturity alignment is the most important factor in debt maturity decisions. Business risk is also a factor considered in funding either by the firm itself, creditor and investor. The purpose of this research is 1) to analyzethe effect of maturity of asset to capital structure 2) to analyzethe effect of business risk to capital structure 3) to analyzethe effect of maturity of asset to debt maturity4) to analyzethe influence of business to debt maturity. Data analysis technique used in this research is multiple linear regression. The test results show the existence of significant asset maturity to the capital structure and the maturity of the debt, while the effect of risk is not significant either on the capital structure orthe debt maturity.

Abstract

The aim of this research was to determine the effect of dietary seaweed of Caulerpa sp. and Gracilaria sp. on blood glucose levels and histological pancreas of diabetic rats. A total of 28 male Wistar rats were used in this study. Rats were divided into 4 groups and given different diets i.e. PSN, PSA, PBN and PBS. Bioassay was conducted for 30 days. The analysis conducted on the macronutrient content of the seaweed flour as well as blood glucose levels on day 0, day 1 and day 30 after alloxan injection. At the end of the implementation of  bioassay, animal surgery were performed and pancreas organs were taken for histology observation. The results showed that  Gracilaria sp. and Caulerpa sp. had a crude fiber content respectively 20.48% and 12.47%. Blood glucose levels in all four groups of mice on day 0 ranged from 123.18 mg / dL - 131.96 mg / dL. Feeding PBN and PBS for 30 days lowered blood glucose levels of mice, respectively for 51.63% (from 384.4 mg / dL to 168.52 mg / dL) and 35.24% (from 328.05 mg / dL be 212.42 mg / dL). Histological observation showed that feeding PBN and PBS capable of helping the regeneration of pancreatic cells, thereby feeding both types of seaweed showed hypoglycemic effects in comparison with standard feed.
