Abstract

This study aims to 1) knowing the effect of calcium acetate and ethanol to the characteristics of bioethanol gel, 2) knowing the adding of calcium acetate and ethanol which gives the best characteristics of bioethanol gel. This study uses a randomized block design factorial design. The first factor is the addition of calcium acetate which consists of four levels: 15 grams, 20 grams, 25 grams, 30 grams and the second factor is bioethanol, which consists of three levels: 75 grams, 85 grams and 95 grams. Variables observed were how long it lasts, viscosity, calorific value, thermal efficiency, the percentage of combustion residue, ash content. The addition of calcium acetate and ethanol concentration and their interactions very significant effect on the characteristics of bioethanol gel. Bioethanol gel with the addition of calcium asetate 20 grams and bioethanol 85 grams of bioethanol with the best treatment that has long lit 3,380 s / g, viscosity 6200 cPa.s, calorific value 4610,596 kJ/kg, the thermal efficiency of 0.47, the percentage of combustion residues 0269%, and % ash content 0.0892.

Abstract

This research were aimed to 1) investigate the effect of curing temperature and curingtime  to bioactive compounds  of  kecombrang  flower  extract  2) to determine an appropriatecuring temperature and  curing  time  that was able to  produce  the  higest  bioactive compoundsof kecombrang flower extract. Solvent used for the extraction was ethanol.This experiment  used  randomized block design with  2 factors. The first factor was the curing temperature consists of 2 levels namely 30 ±2 oC and 40 ±2 oC. The second factor was curing time  consists of 4 levels namely  3 hours,  6 hours,  9 hours  and 12 hours. The objective data analyzed using ANOVA followed by Duncan test and  subjective data analyzed with the Friedman test. This research conducted twice to obtain 16 units experiment. The results showed that  curing temperature and  curing  time  had high  significantly  effect on rendement, tannin, anthocyanin of kecombrang flower extract while the interaction was not significant. Curing temperature, curing time and its interaction had high significantly effect on pH.  The  curing  treatment  at  40 ±2 oC  for 3 hours had the highest  characteristic extract of kecombrang flower at  3.51%  rendement,  4.68  pH,  0.81%  tannin,  2.06  mg/L  anthocyanin,  5.1 score of hedonic (between rather like to like) and 7.10 flavor strength.

Abstract

The aims of this study were 1) to determine the effect of ratio between material and solvent and time of extraction on the yield and characteristics of pandanus fruit extract dyes, 2) to obtain the best ratio between material and solvent, and time of extraction to produce yield and characteristics of pandanus fruit extract dyes. This study used a randomized block design factorial with 2 factors, namely the first factor was the ratio of material with solvent consisting of three levels 1: 7, 1: 9, and 1:11; the second factor was the extraction time ( 3 hours, 5 hours and 7 hours). The experiments were grouped into 2 groups based on the time of its implementation, in order to obtain 18 experimental units. Variables observed were yield, total carotenoid content, and color intensity. The results showed that the ratio between material and solvent affected the yield, total carotenoid content, the level of redness (a*), and the level of yellowness, but did not affected the level of brightness. The time of extraction affected the total carotenoid content, the level of redness (a*) and the level of yellownes, but did not affected the yield and the level of brightness. The interaction ratio between material and solvent, and time of extraction affected the total caroteno id content, the level of redness (a*), and the level of yellowness, but did not affected the yield, and the level of yellowness. Ratio between material and solvent (1:11), and 5 hours time of extraction was the best treatment to produce fruit extract dyes with yield of 2,60%, total carotenoid content of 15,12%, the level of bringhtness (L*) 1,30%, the level of redness (a*) -0,13, and the level of yellowness (b*) 3,59. Keywords: pandanus fruit, dyes, solvent ratio, time of extraction, carotenoid

Abstract

Rosella contains high levels of anthocyanin and can be used as a source of functional dyes. The making of functional dyes is carried out through the process of extraction and encapsulation. The aims of this study were to determine the effect of casein-maltodextrin encapsulation ratio on the encapsulation characteristics of rosella flower functional dye extract and determine the best encapsulation ratio of casein-maltodextrin in producing rosella functional dye extract encapsulates. Experiments in this study used a single factor randomized block design. These factors are the casein and maltodextrin ratio which consists of (maltodextrin), (1: 0.5), (1: 1), (1: 1.25), (1: 1.5), (1: 1.75), (1: 2.0), (1: 2.5) and (casein). The results showed that casein and maltodextrin comparison factors had a significant effect of yield, (P <0.01) on yield, total anthocyanin, surface anthocyanin level, encapsulation efficiency, solubility, brightness (L*), redness (a*), yellowish level (b*) but did not have a significant effect (P> 0.05) on water content. The comparison treatment between casein and maltodextrin 1: 0.5 is a treatment to produce encapsulate products of roselle flower functional dye extract with a yield of 42.86 percent, water content of 5.04 percent, surface anthocyanin total of 9.43 mg/g, surface anthocyanin level 1.66 mg/g, encapsulation efficiency 82.37 percent, solubility 45.84 percent, brightness level (L*) 60.86, redness level (a*) 25.64, yellowish level (b*) 29.61. Keywords: rosella (Hibiscus sabdariffa L.), extraction, casein, maltodextrin, encapsulation.

Abstract

Seaweed is one of the biological resources that its existence is very abundant in all marine waters in Indonesia. One of them is Sargassum polycystum which is a type of brown algae (Phaeophyceae). The purpose of this study was to determine the effect of comparison the material with the solvent to the color content, the total phenolic and chlorophyll of Sargassum polycystum extract, and to determine the comparative treatment of the material with best solvent to produce Sargassum polycystum extract. This experiment uses a simple Group Randomized Design (GRD) consisting 5 comparisons of materials with the acetone (w/v) ie (1:9), (1:11), (1:13), (1:15), (1:17). Furthermore, the treatment is repeated as much as 3 times based on implementation time, to obtained 15 units of experiments. The results showed the ratio of material with the solvent had a very significant effect (P<0.01) on the rendement parameters, brightness (L*), redness (a*), yellowishness (b *), total phenolic, chlorophyll a and total chlorophyll. The results had significant effect (P<0.05) shown on chlorophyll b parameters. The best treatment was obtained from the treatment with the highest value on several parameters tested ie, yield, total phenolic and chlorophyll content. Comparison of material with acetone solvent (1:15) (w/v) was the best treatment with yield of 2.27%, color intensity (L*) 5.08, (a*) -5.62, (b*) 54.00, total phenolic 0.95 mgGAE / 100g, chlorophyll a 279 ppm, chlorophyll b 134 ppm and total chlorophyll 310 ppm. Key words: Sargassum polycystum, compounds bioactive, comparison of material with solvent.
