Abstract

This aims to this study were to (1) determine the effect of addition inoculum Acetobacter aceti andfermentation period on the characteristics of vinegar fermentation from liquid waste of cocoa beansfermentation, and (2) to determine the accurate of addition innoculum Acetobacter aceti and fermentationperiod which one produces the best characteristic fermentation from liquid waste of cacao beansfermentation. The experiments was designed by a Split Plot design with the addition of inoculumAcetobacter aceti into the main plot consisting of 3 plots 10%. 15%. and 20% (v/v). Fermentation period isa subplots consisting of 6 levels were 0. 5. 10. 15. 20. 25 days. The fermentation period was affectedsignificantly (P <0,01) on levels of acetic acid, alcohol content and total dissolved solids from a liquid pulpvinegar fermentation from liquid waste of cacao beans fermentation, while the addition of inoculumAcetobacter aceti and interaction did not affect (P> 0,05). The best characteristics of fermentation vinegarwas found on the addition of an inoculum of 20% and fermentation period for 25 days with the acetic acidcontent, alcohol content and total of soluble solid were 3.21 (% v/v), 0.00%, and 4.79 oBrix. respectively.

Abstract

This study aims to determine the effect of variations in type and concentration of coating material on the characteristics of the cocoa pod extract encapsulate and to determine the best produce cocoa pod extract encapsulate. The experimental design used in this research was a factorial randomized block design, which are grouped into 2 groups based on the implementation time and consisted of two factors. The first factor is the type of coating material (S) which consists of maltodextrin and gum arabic. The second factor is the concentration of coating material (M) which consists of: 5%, 10%, 15%, 20%, 25%. The results showed that the type and concentration of coating material had a significant effect on the yield, water content, solubility, antioxidant capacity, total phenolic and encapsulation efficiency of cocoa pod extract encapsulate. The interaction between treatments had a significant effect on the yield, solubility, antioxidant capacity, total phenolic and encapsulation efficiency, but had no effect on the water content of the encapsulated cocoa pod extract. The best treatment was obtained using gum arabic of 5% concentration coating material, with characteristics of 84.81±0.15% yield, 7.10% water content, 84.26±0.06% solubility, 80.12 ±0.24 mg GAEAC/g antioxidant capacity, 113.77±0.24 mg GAE/g total phenolic, and 78.16±0.60% encapsulation efficiency.

Abstract

Microemulsions have thermodynamics and stable kinetics as carriers of ?-tocopherol compounds. This study aimed to know the effect of mixtures ratio of three nonionic surfactants and stiring time on the characteristics of ?-tocopherol microemulsion, as well as to obtain the best stiring time and mixture ratio of three nonionic surfactants to produce ?-tocopherol microemulsion. This experiment used a randomized block design with two factors. The first factor is the ratio of a mixture of three nonionic surfactants with Hydrophilic-Lipophilic Balance (HLB) 14.5. The second factor is stirring time. Data were analyzed using analysis of variance and continued with BNJ test. Test the effectiveness index to determine the best treatment. The results showed that the comparison of three surfactant mixtures, stirring duration and interaction between treatments significantly affected the characteristics of ?-tocopherol microemulsion. Comparison of the mixture of three surfactants Tween 80: Span 80: Tween 20 (v / v%) HLB 14.5 consisting of F2 (89,5 : 5,5 : 5) and 4 minutes stirring time is the best treatment for the characteristics of ?-Tocopherol microemulsion. The best treatment has the characteristics of ?-tocopherol microemulsions namely transparent appearance, stable to centrifugation (4500 rpm), pH (4.5; 5.5 and 6.5) and dilution (1: 9, 1:49 and 1:99) with Turbidity index values ??are below 1 percent. Microemulsion turbidity index values ??before and after centrifugation were 0.19 percent and microemulsion turbidity at pH 4.5 and 1: 9 dilution were 0.11 percent.

Abstract

Cocoa bean husk is a waste of cocoa processing that is large enough and has not been used optimally. Cocoa bean husk waste can be used more optimally by extracting polyphenol compound and used as natural antioxidant. This research aims to determine the effect of the type of solvent and maceration time of cocoa bean husk extract as a source of antioxidants and to determine the best type of solvent and maceration time to produce cocoa bean husk extract as a source of antioxidants. This experiment uses a randomized block design with two factors. The first factor is the type of solvent consisting of methanol 95 percent, ethanol 96 percent and acetone 90 percent. The second factor is the maceration time consisting of 24, 36 and 48 hours. The data is analyzed by variant analysis and continued with the Tukey test. The results showed that the type of solvent and maceration time is a very significant effect on yield, total phenolic and antioxidant capacity. The interaction between treatment is a very significant effect on total phenolic and antioxidant capacity but did not significantly affect the yield of cocoa bean husk extract. The best treatment to produce cocoa bean husk extract as a source of antioxidants is using ethanol solvent and maceration time for 48 hours with a yield characteristic 11.72±0.45 percent, a total phenolic at 80.76±1.12 mg of GAE/g and Antioxidant capacity 49.55±1.13 mg GAEAC/g. Keywords : cocoa bean husk, extraction, solvent, antioxidants.

Abstract

Sargassum polycystum is one group of brown algae (Phaeophyta) which contain fukoidan compounds. Fukoidan is a complex polysaccharide on seaweed cell walls that can enhance immunity by stimulating the production of immune cells. The purposes of this study were to determine the effect of particle size and extraction time of Sargassum polycystum against fukoidan characteristics and get particle size and extraction time which is the best treatment for getting extraction Sargassum polycystum as an antibacterial. This experiment used a randomized block design with particle size treatment and extraction time. Treatment of 40, 60, and 80 mesh particle sizes and extraction lengths of 3, 4 and 5 hours. The results showed the treatment of particle size, extraction time and interactivity affect the characteristics of brown algae extract (Sargassum polycystum) as an antibacterial. 80 mesh particle size treatment and extraction time of 5 hours is the best treatment to produce brown algae extract (Sargassum polycystum) as an antibacterial with characteristic sulfate content of 15.297 mg / L, inhibitory zone in Escherichia coli with a diameter of 10.15 mm and inhibit zone Staphylococcus aureus with a diameter of 9,13 mm.

Abstract

This study aims to determine the characteristics of waste cooking oil in Denpasar to be known the quality of waste cooking oil so that utilization is not for consumption again but processed into non-food products with the appropriate preliminary treatment. The population in this research is all waste cooking oil produced in Denpasar city. Determination of research sample was done by using purposive sampling method with some consideration such as (1)Choice of hotel and restaurant with average occupancy above 70%/year, (2) Street food vendors and street snack vendors with daily proccess using 10 L cooking oil a day. So that obtained 21 samples of waste cooking oil from the three sources of sampling. The observed variables are water content, peroxide number and free fatty acid. The results showed that waste cooking oil which has the highest water content from the street food vendor amount 0,40%, while the lowest from hotel/restaurant amount 0,09%. The highest peroxide rate were obtained on street snack vendors amount 13,27 MeqO2/1000 while the lowest were hotel/restaurant amount 12,76 MeqO2/1000. The highest free fatty acids were obtained by street food vendor amount 0,35%, while the lowest from hotel/restaurant amount 0,19%.
