Abstract

This research objective has to show the effectivity of the using biosorbent Papaya seed to recondition of fried oil quality.  The adsorption mechanizme and the factors effected to performance of biosorbent must studied Comprehensively. Totality of extent particle surface and the long time of biosorbent with adsorbed interface determined performance adsorption. The research was compiled to producing and activating Papaya seed as biosorbent; and then to do the experiment for effectivity biosorbent according with Complete Random Factorial Design, with two factor namely Mass biosorbent to Volume fried oil ratio (A1=5 %, A2 = 10 %, A3 = 15 %, dan A4 = 20 % (b/v) , and the long time of biosorbent fried oil interface (L1 = 2, L2 = 4, L3 = 6, dan L4 = 8 days).  The result of data analysis to show that  effect of Mass biosorbent to Volume fried oil ratio factor have significant  different  among factor level properly (p<0.05), the mean value of Peroxide Number, Free Acid Number, and Water Content of fried oil  were tendence to below.  But the value of organoleptic colour was increase.  Effect of the long time of biosorbent fried oil interface have significant  different  among factor level properly (p<0.05), the  mean value of Peroxide Number, Free Acid Number, and Water Content of fried oil  were tendence to increase, and the value of organoleptic colour were also.

Abstract

The research objectives determine the effect of concentration Wild Ginger starch in suspension and adding glycerol on the edible film making of wild ginger starch.  The Factorial Complete Randomized design was used with two factors. The first factor as treatments were  the number of concentration Wild Ginger Starch in suspension (T) at four levels namely T1=2%, T2 = 4%, T3 = 6%, T4 = 8%.  The second factor as treatment was the number of concentration glycerol adding (G) at four levels namely G1 = 20%, G2 = 30%, G3 = 40%, G4 = 50%. The physical characteristics  film were observed as Parameters namely The film thickness, percentage elongatios of film, and Water Vapor Transmission Rate (WVTR). The statistical analysis of the parameters indicated that increasing concentrations of  wild ginger starch in suspensions  very significantly difference effect (P<0,01) for film thickness,  percentage elongation of film, and Water Vapor Transmission Rate (WVTR). The increasing of glycerol adding very significantly difference effect (P<0,01) for film thickness, and percentage elongation of film. Unlike the Water Vapor Transmission Rate (WVTR) was significantly difference effect (P<0,05). Treatment interactions gave a very significantly different effect (P<0,01) for the thickness, and percentage  elongation of  film. Unsignificantly difference effect (P>0,05) for Water Vapor Transmission Rate (WVTR).Keywords: Wild ginger starch, glycerol, WVTR, edible film.

The purpose of this study was to determine the rate of addition of papaya right to characteristic of catfish nuggets. The design used was completely randomized design (CRD) with 4 treatments and 3 replications. Then do the analysis of variance, followed by Duncans test New Multiple Range Test (DNMRT) on the real level of 5%. The treatment used is the addition of papaya leaves ranging from 0 g (A), 5 g (B), 10 g (C) and 15 g (D) into 100 grams of material. Data were collected for catfish nugget products include: moisture content, ash content, protein content, crude fiber content, fat content, oil absorption power, identification of alkaloids, β-carotene content, physical analysis, total plate test and organoleptic (color, aroma , taste and texture).The results showed that the addition of 10 grams of papaya leaves are still acceptable to the percentage of panelists who expressed love to really like the color as much as 95%, 85% aroma, flavor and texture of 65% to 80%. Chemical analysis of water content obtained 53.37%, ash content 1.41%, 12.22% protein content; levels of fat before frying 1.88%; levels of fat after frying 9.01%, 2.15% crude fiber; power oil absorption 7.13%; identification alkaloid (+ +); β-carotene content before frying 1993.2201 microg; once fried 1089.0280 microg; violence before frying 3.99 N / cm ², and after frying 2.71 N / cm ² and the plates a total of 1.1 x 104 CFU / g. Keywords: papaya leaves, nugget, catfish, β-carotene and alkaloids

Abstract

Addition of the substance will effect the value of carbon equivalent (CE) cast iron. Carbon equivalent value is a parameter that tells us how much carbon is cointained in the cast iron. Carbon equivalent values were determined between 4,7 to 4,9. When the carbon equivalent (CE) on the cast iron is less than 4.7 to 4.9 then it will be easy to cast iron, causing cracks in the baked anode rod will come loose. And usage cast iron is not optimal. And when more than that value so cast iron will difficult loose from the anode rod. From the observations that have been made obtainable carbon equivalent (CE) cast iron are 3,76 and 4,7. This indicates that the value of carbon equivalent (CE) cast iron still eligible and meet the standars that have been established which is between 4,7 to 4,9.

Abstract

Endophytic bacteria repoted can produce metabolite as antifungal compound. This study was aimed to knowing and obtain antifungal compound wich are produced of endophytic bacteria to control fungal pathogen. Isolation of endophytic bacteria was done using surface sterilization method, furthermore hypersensitive reaction test of bacteria was done for selection pathogenicity of bacteria. Endophytic bacteria was tested their antagonism against fungal pathogen for selection the potential of endophytic bacteria. Isolate of endophytic bacteria which have highest growth inhibitor would be extracted and analyzed the antifungal compound. The result showed that threeisolate of endophytic bacteria wich one potentially in inhibiting fungal pathogen are isolate EF14III, ER1I and ER101. Isolate bacteria ER1I was the most effective in inhibiting the growth of fungal pathogen. Antifungal compound in isolate bacteria ER1I are fenol, lauric acid, propenoic acid, and cyclohexanone.Keywords: Antifungal compound, Endophytic Bacteria, Fungal pathogen

Abstract

The noodle circulating in the market and which we often consume the main ingredient is wheat flour so that the nutrient components such as fiber and carotenoids contained in noodle is very minimal. To increase the content of fiber and carotene noodle it is necessary to substitute flour with local food containing fiber and carotenoids. For example breadfruit and pumpkin. This study aims to determine how the influence of the amount of pumpkin paste and breadfruit as the substitution of flour to the characteristics of wet noodles and to the color preferences test and to determine the effect of storage duration on carotenoid content of wet noodles. The experiment was conducted by non factorial randomized design by comparing the amount of pumpkin paste to breadfruit paste and storage duration. The results showed that water content, ash content and protein content were not influenced by the ratio of the number of pumpkin paste to breadfruit paste. But the fiber content increased from 1.22% to 3.16% and carotenoid levels from 0.07 ppm to 0.10 ppm. The color preference level increases from 1.86 (dislikes) to 3.35 (like). Time storage can lower carotenoid levels from 0.105 ppm at 0 days storage to 0.08 ppm at 4 days. The conclusion of flour substitution with breadfruit paste and pumpkin paste can increase the fiber content and wet carotenoid noodles. Storage results in decreased carotenoid levels.

Abstract

Palm briquette briquette production as one of the fuel substitutes that began to thin and as a source of renewable alternative energy is done with the addition of cassava starch. This research used Factorial Randomized Complete Design (RAL) with two replications. Factor I is the addition of cassava husk starch with a password (P) consisting of 4 levels, namely: P1 = 5%, P2 = 10%, P3 = 15%, P4 = 20%. Factor II is the drying temperature with the code (S) consisting of 4 levels, namely: S1 = 1000C, S2 = 1100C, S3 = 1200C, S4 = 1300C. Parameters observed included heating value, moisture content, ash content. Statistical analysis result on each parameter show: The addition of Cassava Starch has a very significant different effect (P <0.01) on the calorific value. The addition of Cassava Starch gave a very significant different effect (P <0.01) on Briket Water Content. The addition of Cassava Starch gave a very significant different effect (P <0.01) on Ash Content in Briquette.Keywords : Cassava leaf,  palm stem, briquettes, calorific value
