Abstract

The aims of this study were to 1) determine the influence of curing time and extraction time, on the rendement and characteristics of essential oil of pandan wangi leaves 2) get curing time and extraction time procses to produce the highest yield and the best characteristics essential oil of pandan wangi leaves and 3) determine the type and composition of compounds in the essential oil of pandan wangi leaves. This research used randomized block design with factorial pattern. The first factor (curing time) consists of 3 level namely without curing, the 2 and 4 days process time, the second factor (extraction time) consists of 3 level using the 2, 3, and 4 hours process time. Each treatment grouped into 3 groups based on the time implementation. Objective variables measured were yield, and composition profiles of compounds in essential oil of pandan wangi leaves. Subjective variabel measured were the preference of aroma and aroma strength of the essential oil of pandan wangi leaves. The best treatment was determined with effectiveness index. The results showed that the curing time and extraction times had significant effect on the rendement and characteristics of essential oil of pandan wangi leaves. The extraction time of 3 hours and material conditions of curing 4 days was right treatment to produce essential oil of pandan wangi leaves with the highest rendement and the best characteristics, namely rendement 1.983 %, the aroma preference of 5.2 (between like and really like) and aroma strength 6.4. essential oil of pandan wangi contain 36 kinds of compounds with 16 compounds were not identified. Constituent compounds consists of classes alkane (46,66%), alkene (31,22%), aldehid (11,13%), and not identified (10,89%).

Abstract

Bidara (Ziziphus mauritiana L.) is widely grown in the tropics. Bidara is rich in benefits because it has content of saponins contained in the leaves. Saponins compounds derived plants can be used as soap foaming agents. Saponins can be applied in the manufacture of soap because of its nature as a natural surfactant. The purpose of this study were to determine the influence of solvent type and particle size of materials againts on the characteristics bidara leaf extract as a source of saponins, get the best solvent type and particle size to produce bidara leaf extract as a source of saponins. This study used a Randomized Block Design with treatment of solvent type and particle size of materials. Treatment of solvent type consists of 3 levels, namely: methanol, ethanol and acetone. The particle size of materials treatment also consists of 3 levels, namely: 40 mesh, 60 mesh and 80 mesh. Each treatment are grouped into two-based implementation. The results showed that treatment of solvent type and particle size of materials very significant effect on yield, coarse extract saponins content and foam height leaves bidara as a source of saponins. Interaction between treatments very significant effect on yield and foam height. However, significant effect on coarse extract saponins content bidara leaves. The methanol solvent type treatment with particle size of material 80 mesh is the best treatment to produce bidara leaf extract as a source of saponins with value yield of 17.91±0.73 %, 20.40 ± 0.79% coarse extract saponins content and foam height of 8.27 ± 0.01 mm.

Abstract

ABSTRACT Byproducts of fermented cocoa beans can be processed into cocoa vinegar. Cocoa vinegar produced is still cloudy, so it needs to be clarified. This study aims to determine the effect of type and concentration of fining agent on the characteristics of cocoa vinegar and to determine the type and concentration of the best fining agents to clarified cocoa vinegar. This study used a factorial Randomized Block Design consisting of 2 factors. First factor is a type of fining agent consisting of bentonite, chitosan and gelatin, and second factor is a concentration of fining agent consisting of 0.5, 1, 1.5, 2, 2.5 ppm. Treatments are grouped into 2 groups to obtain 30 experimental units. The variables observed were clarity, pH, total dissolved solids, total acid, and acetic acid levels. The results showed that the type and concentration of purifying agents had an effect on the characteristics clarity, total dissolved solid, degree of acidity (pH), total acid, and acetic acid level of cocoa vinegar. The best treatment to clarify cocoa vinegar is the treatment of chitosan digesters with a concentration of 2 ppm, which produces cocoa vinegar with characteristics of clarity of 0.46 A; total dissolved solids of 2.90oBrix, degree of acidity (pH) of 4.11; total acid of 0.33 mEq NaOH/g, and acetic acid level of 1.96% w/w. Keywords: Cocoa, vinegar, fining, bentonite, chitosan, gelatin
