Abstract

This research is  study of  inhibition power between rubber cassava leaves extract (Manihot glaziovii) and noni (Morinda citrifolia l.) in reducing Eschericia coli contamination in vannameii shrimps (Litopenaeus vannamei). Cassava leaves contains flavonoids, saponins and tannins while noni contains antraquinone and scolopetin which has antimicrobial activity. This research aim at determine antimicrobial activity of cassava leaves extract and noni to inhibit Eschericia coli contamination in vannamei shrimps and determine the best formulation. The research use non-factorial complete randomized block design (RAKL) experimental design with three replications. The formulation in each treatment being used contained 25% (b/v) of the solvent. The treatments used in this study were M0S0 (control), M1S1 (25: 0), M2S2 (20: 5), M3S3 (15:10), M4S4 (10:15), M5S5 (5: 20), M6S6 (0:25) .Data were tested with the Barlett test and the Tuckey test to see the homogeneity. The data analysis was carried out using fingerprints to see the effect of treatment on the parameters being observed and followed with LSD test. The observations of research contained test of  amount Eschericia Coli, Antimicrobial Inhibition, Eschericia coli Total Decrease, Antimicrobial Activity Application, pH test, and Sensory Testing (Color and Appearance). The results of this research showed that the extract of noni was more effective in inhibiting the contamination of Escherichia coli in vannamei shrimps with an inhibition zone of 7.23 mm compared to cassava leaves with an inhibition zone of 0.43 mm.  The formulation has been obtained that the ratio between extracts of rubber cassava leaves and noni was  25%: 0% is best formulation to inhibit the microbial activity zwith the zone of inhibition is 7.23 mm.  Keywords: Vannameii Shrimps, Rubber Cassava Leaves, Noni, Escherichia coli

Abstract

This study aims to determine the effect of carrageenan and gum arabic formulations on chemical properties, level of elasticity, and sensory properties of pumpkin jelly candy and to obtain the right formulation of carrageenan and gum arabic to produce good quality jelly candy. The study was arranged in a Completely Randomized Block Design with a single factor and 4 replications. The treatment was the ratio of carrageenan and gum arabic consisted of 5%:0% (K1), 4%:1% (K2), 3%:2% (K3), 2%:3% (K4), 1%:4 % (K5). The data obtained were analyzed for homogeneity with the Barlett test, ANOVA, and the Tuckey test at the 5% level.  Determination of the best treatment for pumpkin jelly candy was determined by the De Garmo method.  The results showed that the best jelly candy was the K3 treatment (3% carrageenan; 2% gum arabic) which resulted in a texture score of 3.80 (chewy), color with a score of 3.97 (dark yellow), taste with a score of 4.11 (like ), water content of 7.66%, ash content of 0.99%, reducing sugar content of 14.31%, and sucrose content of 27.7%.  Formulation of carrageenan and gum arabic significantly affected the chemical properties, level of elasticity, and sensory properties of pumpkin jelly candy. Keywords: Gum Arabic, Carrageenan, Jelly candy, Pumpkin.

Abstract

Spices have always been a part of Indonesia's culinary culture. One of the spices that has high economic value and efficacy is galangal. Therefore, testing of bioactive compounds and the effect of making shredded spice fish with the addition of various concentrations of galangal needs to be further investigated in terms of sensory quality and financial feasibility. This study aims to determine the bioactive components in galangal spice, determine the best concentration of galangal addition in shredded spiced fish products, and determine the financial feasibility. The research was conducted by making galangal spice and shredded spiced fish at IDAEZ Group MSMEs. Subsequently, the galangal spice was tested for bioactive compound (GC-MS) and then, sensory tests were carried out on shredded fish spices mixed with galangal spices (1%, 2%, 3%). After that, the financial feasibility analysis was calculated. The results obtained showed that there were four main components in galangal spice, such as 5-Eicosenen, (E)-, n-Hexadecanoic acid, oleic acid, and 9-Octadecenoic acid (Z)-, oxiranylmethyl ester. Meanwhile, the best concentration of shredded spice fish was found in treatment P3 (addition of 3% galangal). Lastly, the shredded spice fish was found to be viable with an income of IDR 427,547 per production. Keywords: Financial feasibility, GC-MS, Galangal, Sensory.
