Abstract

Fabrication of edible film from papaya extract ( Carica papaya L.) with tapioca , wheat and glycerin mixture has been successfully conducted. The edible film was made by mixing papaya extract, tapioca, wheat, and glycerin until homogeneous and poured on the plastic plate then dried in an oven for 2 days at 40ºC with the comparison of tapioca: wheat (7.5 g: 2.5 g) and (5 g: 5 g). Edible films produced were then tested for their characteristics and nutrient levels. The results show that the edible film with the comparison of tapioca: wheat (7.5 g: 2.5 g) show a good result with the characteristics which include thickness tensile strength, elastic and SEM that is 0.193 mm; 0, 1442 Kgf/mm-2; 48.82% and making a film with the structure that has tight pores, compatible, and smooth. The levels of nutrients were water, ash, protein, fat, carbohydrates, and beta carotene from the edible film were 16.23 %; 2,921 %; 5.44 %; 1.76 %; 73.65 %, and 116.052 ppm, respectively. The organoleptic test results show good results that the panelist liked the edible film.

Abstract

Monoglyceride and diglyceride have high economical value and are needed in the food/pharmaceutical, cosmetic, and cleaner product industry as surface agents and emulsifiers. Producing monoglyceride can be done by hydrolysis, glycerol esterification of fatty acid, and glycerolysis. This research aims to produce monoglyceride and diglyceride from palm kernel oil by glycerolysis catalyst Candida rugosa enzyme with a variety of solvents such as 1-propanol, 2-propanol, n-heptane, and isooctane. The glycerolate was analyzed by thin-layer chromatography, it showed that the retardation factor (Rf) value of monoglyceride fraction from glycerolate using n-heptane as the solvent was 0.07, and the retardation factor (Rf) value of diglyceride fraction from glycerolate using 1-propanol as the solvent was 0,2. Each of the fractions was analyzed by gas chromatography showed that the high percentage of monoglyceride was produced by glycerolysis using n-heptane which yielded 14,06% and the high percentage of diglyceride was produced by glycerolysis using 1-propanol which yielded 77,51%. The solvents which can be used in enzymatic glycerolysis and can yield high percentages of monoglyceride is n-heptane and the high percentage of diglyceride was conducted by enzymatic glycerolysis using 1-propanol.

Abstract

Synthesis of 2-((furan-2-yl) methylene)-1-phenylhydrazone has been carried out by reaction of condensation of furfural aldehyde groups obtained from the isolation of corn cobs with phenylhydrazine. Furfural condensation with phenylhydrazine was carried out by refluxing in ethanol solvent for 1 hour. Of the 9.6 g (0.1 mol) furfural which was condensed with 5.4 g (0.05 mol) phenylhydrazine obtained yield of 10.54 g (67.02%) phenylhydrazone which was then analyzed by FT-IR spectroscopy showing the presence of vibration C = N in the area around 1597 cm-1. Fenilhidrazone was tested for inhibitor with 78.47% and compared with furfural as much as 58.18%, and phenylhydrazine as much as 50.04%. The results obtained by phenylhydrazone were more efficient at inhibiting the results of 78.47% while furfural and phenylhydrazine were only 58.18% and 50.04%.

Abstract

The preparation of edible film from carrot extracts (Daucus Carota, L) with the addition of tapioca flour, wheat flour, and glycerin was carried out. The edible film was prepared by mixing carrot extract, tapioca flour, and wheat flour, and then heated and added with glycerin and stirred up. The homogeneous solution was put into an acrylic plate to form an edible film and dried in an oven at 40oC for ± 2 days. The edible film formed was characterized and analyzed its nutrition content. The tensile strength and elasticity of edible film with a ratio of 5 g tapioca flour and 5 g wheat flour were 0.1028 KgF/mm2 and 39.83% respectively. The thickness of edible film with a ratio of 2.5 g of tapioca flour and 7.5 g of wheat flour 7.5 g was 0.26 mm. The better nutrition content was found on edible film with a ratio of 5 g tapioca flour and 5 g wheat flour which has 13.94% moisture content, 2.67% ash content, 4.93% protein content, and 2.90% fat, 75.56% carbohydrate content, and 410.34 ppm carotene content. Organoleptic test edible film of color, taste, texture, and aroma gave an average score of 3 (like), because of the shiny color, crunchy taste, smooth texture, and interesting edible film. Based on the test indicated that people accepted the edible film produced.

Abstract

Liquid waste from the steel industry processing, washing machine, and kitchenware foundry contained the elements of copper (Cu), chromium (Cr), and manganese (Mn). The effluent samples were destructed using concentrated HNO3. Then determined the concentration of the elements copper (Cu), chromium (Cr), and manganese (Mn) using an Atomic Absorption Spectrophotometer with a calibration curve. The results obtained for the level of copper (Cu) on the sample inlet was 0.9714 mg/L to 0.9719 mg/L, and the sample outlet was 3.9990 mg/L to 4.0002 mg/L. Levels of the element chromium (Cr) on sample inlet was 0.0295 mg/L to 0.0297 mg/L, the sample outlet was 0.0399 mg/L to 0.0400 mg/L. Meanwhile, the level of manganese (Mn) in the sample inlet was 0.1269 mg/L to 0.1271 mg/L in a sample outlet was 2.9699 mg/L to 2.9701 mg/L. Then the steel industry wastewater for elemental copper (Cu) and manganese (Mn) exceeded the limits that have been instituted by the Minister of Environment Decree No. 51, 1995, regarding the Liquid Waste Quality Standard for Industrial Activity.
