The purpose of this research was to obtain the best addition of red ginger powder in making herbal tea of avocado leaf. This research used a Completely Randomized Design with five treatments and three replications. The treatments used were BJ1 (without addition of red ginger powder), BJ2 (addition of red ginger powder 2%), BJ3 (addition of red ginger powder 4%), BJ4 (addition of red ginger powder 6%), and BJ5 (addition of red ginger powder 8%). The result showed that addition of red ginger powder significantly effected water content, ash content, antioxidant activity (IC50), polyphenol content,  and sensory assesment descriptively and hedonically and also overall assesment. The treatment chosen from the result was BJ5 (addition of red ginger powder 8%).  This treatment had water content 4.43%, ash content 5.57%, and antioxidant activity (IC50) 44.63 µg/mL. The best treatment on descriptive test of herbal tea had tawny colour, no rotten flavour, and rather bitter and spicy.  The result of hedonic test showed that colour, flavour, and taste of herbal tea were preferred by panelists and also assessment overall preferred by panelists.

Aquilaria is one of the plant genus-producing agarwood. Aquilaria leaves have pharmacological effects which the potential to be processed into black tea. The aim of this study is to determine the effect of fermentation duration on physicochemical and organoleptic characteristics of Aquilaria leaves tea. This study employed a Completely Randomized Design with two factors; the plant species (A. crassna, A. malaccensis, and A. subintegra) and fermentation duration (0 minutes, 70 minutes, and 90 minutes). Parameters analyzed including water content, total phenol, and antioxidant activity. Organoleptic tests were performed on the color, taste, and aroma of the brewed tea. The results summarized that A. subintegra had the highest total phenol and antioxidant activity, but the taste of the tea was not favored. A. crassna fermented 70 minutes and A. malaccensis fermented 0 minutes were the most preferred, but both have lower total phenol and antioxidant activity than A. subintegra.

THE UTILIZATION OF RED GINGER POWDER (Zingiber officinale var. Rubrum) ON ORGANOLEPTIC CHARACTERISTIC OF MUTTON MEATBALLS. This study was conducted to evaluate the utilization of red ginger powder on the organoleptic characteristic of mutton meatballs. The materials used were fresh mutton meat on the hamstrings, tapioca flour, salt, flavoring, garlic, pepper, red ginger powder, ice cubes and processing equipment tools. The experimental design used in this study was a Completely Randomized Design of five treatments with 30 replications. The treatment was 300 g of meat and 0 g red ginger powder (R0), 300 g of meat and 1.5 g red ginger powder (R1), 300 g of meat and 3.0 g red ginger powder (R2), 300 g of meat and 4.5 g red ginger powder (R3), and 300 g of meat and 6 g red ginger powder (R4). Organoleptic testing performed was using the hedonic quality test. The variables measured consisted of color, flavor, taste and elasticity of meatballs. Determination of the average difference among treatments was done by Tukey (HSD) test. The results showed that the treatments affected significantly on flavor and taste. However, treatments did not affect significantly on color and elasticity of meatballs. The use of 3g red ginger powder could provide acceptance levels on organoleptic characteristic of mutton meatballs. Keywords: Mutton meat, red ginger, Meatballs

This study aimed to determine the effect of emprit ginger powder (Zingiber officinale var. Amarum)  on the characteristic of sweet orange peel herbal tea (Citrus sinensis L.) as well as the appropriateness of emprit ginger powder for the best characteristic. This study was designed using an experimental method which is Completely Randomized Design with the treatment of adding emprit ginger powder (0%, 5%, 10%, 15%, 20%) that was repeated  3 times  to obtain 15 experimental units. Observed variabels were water content, extract water content, vitamin C, total phenolic, total flavonoid, antioxidant activity, scoring test, and hedonic test. The obtained data were analyzed by using the analysis of variance. If it had a significant effect, it was continued to be tested by using the Duncan Multiple Range Test. The results showed that the addition of  emprit ginger powder had a very significant effect on the water content, vitamin C, total phenolic, total flavonoid, antioxidant activity, aroma (scoring and hedonic test), taste (scoring and hedonic test), and overall acceptance, while extract levels in the water had a significant effect and color (hedonic test) had a non significant effect. Furthermore, it showed that the addition of 20% emprit ginger powder extract was the best treatment with the characteristic as follows: 8.13% w / w water content, 26.93% w / d extract water content, vitamin C 25.56 mg / g tea powder, total phenol 17.86 mg GAE / g tea powder, total flavonoids 1.17 mg QE / g tea powder, and antioxidant activity 56.89%.

Black garlic is a garlic that experiences warming at a certain temperature and time to find higher antioxidant activity. This research aimed to know effect of antioxidant content’s stability of extract BG to pH and temperature. The experimental design used in this research was a completely randomized design with replication, which consisted of two factors. The first factor was pH (4, 6 and 8). The second factor was temperature (30, 50 and 70ºC). Data were analyzed with analysis of variance, followed by Duncan test. The results showed that pH and processing temperature very influential to antioxidant activity, total phenolic and total flavonoid. The results showed that the best treatment was pH 4 and temperature 30ºC which the best resulted antioxidant activity, total phenolic and total flavonoid that stablest. The resulted of antioxidant activity, stability of total phenolic and total flavonoid that were 75,13%, 42,47% and 77,71%. The treatment of pH and processing temperature change compounds of extract black garlic. Myricetin and quercetin appeared on treatment pH 4 with temperature 30ºC and pH 8 with temperature 70 ºC. The treatment of pH and processing temperature of black garlic extract reduced antioxidant activity, total phenol and total flavonoid. pH and temperature form new compounds.
