Abstract

The purpose of this research was to observe antioxidant activity of lotus leaves extract (Nelumbo nucifera). The extraction  process was carried out using three different solvents namely methanol, ethyl acetate and n-hexane. The observed parameters were extraction yields phytochemical compounds (alkaloid, flavonoid and tanin) and antioxidant activity using DPPH method. The results showed that the methanol extract exhibited the highest yield with a value of 0.708% and had a flavonoid tannin content of 1161 ppm. The antoxidant activity of the same extract as indicated by IC50 value was 199 ppm. The extract ethyl acetate and n-hexane solvents did not show potential antioxidant activities

Abstract

The purposes of research were to maintain the quality of snakehead fillet and to know the effect of low concentration addition salt, sucrose and citric acid and different storage time on the quality of snakehead fillet stored at 40C. The experiment was arramged in a randomized block factorial design with two replications. The first factor was different solvent addition, the second factor was storage time. Observation parameters included physical analysis (WHC), chemical analysis (TVB) and microbiological analysis (TPC). The result showed that the value of WHC, TVB and TPC on A2 factor has lower than the other factors. The value of WHC, TVB and TPC increased during storage. The limit total of microbes was permissible for A0 treatment until day 9th is 5.60 log10 cfu/g (3.9 x 105), A1 until day 9th is 5.46 log10 cfu/g (2.9 x 105), while A2 treatment until day 18th is 5.60 log10 cfu/g (3.9 x 105).

Abstract

The objective of this research was to determine the effect of substitution of glutinous rice flour with seaweed for proximate, physic, sensory and microbiology. The research was conducted in March and April 2014 in Laboratory of Fisheries Technology and Laboratory of Bioprocess, Chemical Engineering Department, Sriwijaya University, Indralaya. This research used non factorial complete randomized design with four treatments and repeated twice. Glutinous rice flour was substituted with different concentration of seaweed A1 (12.5%), A2 (25%), A3 (37.5%), A4 (50%). The parameters observed were proximate analysis (water content), texture analysis, sensory (colour, texture and taste) and microbiology test. The results showed that substitution of glutinous rice flour with seaweed was not significant on hardness and water content. Based on analysis, the composition of the value obtained around 23.83-29.83% water content and 184.6-349.34 gf hardness analysis. Hedonic test was significant on colour and taste but not significant on texture. Microbiology test showed that engkak ketan is safe for eat on H0

Abstract

The purpose of this research was to know the effect of formaldehyde treatments on chemical and sensory characterstics of fresh yellow stripe scad fish. This research used Factorial Completely Randomized design with two treatment factors and repliecated tree times. The treatment consist of the different formaldehyde concentration (0%, 25% and 50%), and self time (1, 3 and 6 days). The parameters observed were chemical characterstics (content of water, concent of protein, concent of formaldehyde), microbiology analysis (total plate count testing) and organoleptic characterstics (sensoris testing, score test method). The result of the research showed that the interaction of increasing of formaldehyde concentration and self time had significant effect on the  water and  formaldehyde content of yellow stripe scad fish. The factor increasing of formaldehyde concentration had significant effect on the  protein content. The result of microbiology test (total plate count) showed that total of bacteria yellow stripe scad fish in formaldehyde treatment 0%  was higher than increasing of formaldehyde concentration 25% and 50%. The organoleptic test showed that formaldehyde treatment 0% was stated fresh at first day, decline of quality at the third day and getting stinky at the sixth day. Yellow stripe scad fish with the treatment of concentration formaldehyde 25% stated decline of quality at the sixth day, whereas yellow stripe scad fish with formaldehyde treatment 50% still stated in fresh condition at the sixth day

Abstract

The objective of research was to investigate chemical and physical characteristics especially of amino acids and antioxidative activity of paste made from boiling water snakehead and mackerel head with different concentrations of coconut sugar. The research used Factorial Randomized Completely Design with 2 type of fish and 4 concentration of coconut sugar then two replicated. The treatment from types of fish (snakehead and mackerel) and concentration of coconut sugar (10%, 20%, 30%, and 40%). Parameters obsevased were chemical analysis (water content, protein content, fat content, ash content,  carbohydrates content, amino acids, and antioxidative activity), physical analysis (viscosity) and sensory testing (appearance, texture, odor and taste).  The result showed that the treatment types of fish were significant on 5% level test on water content, fat content, and carbohidrate content. The treatment  concentration of coconut sugar were significant on 5% level test affected in water content, protein content, fat content, ash content, carbohydrate content, and viscosity. But both of these treatments hadn’t effect on sensory paste. Based on SNI 01-2718-1996, the best treatment was combination of A1B1 (snakehead, 10% concentration) and A2B1 (mackarel, 10% concentration) with water content 20,85% and 20,8%, protein content 22,2% and 20,73%, fat content 7,9% and 9,7%, ash content 6,2% and 6,65%, carbohidrate 42,9% and 39,3%, viscosity 205cp and 197cp, antioxidative activity 14.028 ppm and 13,847 ppm, amino acids 7,89% and 8,93 %.

Abstract

The objective of this research was to investigate the physical and chemical characteristics of bivalvia pempek (Pilsbryoconcha sp.) by using fasting pre-treatment bivalvia to the raw material and different pempek formulation. This research was conducted on February until July 2014 at the Laboratory of Fishery Product Technology, Chemical Laboratory of Technology of Agricultural, Faculty of Agriculture, and Bioprocess Laboratory of Department of Chemical Engineering, Faculty of Engineering, Sriwijaya University. The Factorial Randomized Block Design was used with two treatment factors that were repeated twice. The treatment factors were consisted of pre-treatment to the bivalvia (without fasting and fasting for 24 hours) and comparison of  the composition of bivalvia meat and tapioca flour (1:2, 1:1, and 2:1). Parameters observed were physical analysis (gel strength and degree of white) and chemical analysis (water content, ash, protein, fat, and carbohydrate). The results of this research showed that average value of gel strength of bivalvia pempek ranged from 208.20 gf to 463.70 gf and degree of white percentage ranged from 45.47% to 51.33%. The average value of the water content ranged from 85.50% to 84.20%, ash content from 0.55% to 0.90%, protein content from 3.82% to 7.31%, fat content from 1.26% to 1.91%, and carbohydrate content from 9.83% to 12.05%. The best treatment was fasting pre-treatment by using water for 24 hours with a ratio 50% of bivalvia meat and 50% of tapioca flour (1:1)
