Abstract

Industry Packaging produced the product than package used directly as food or material packaging to protect and secure the products. Therefore, it is necessary to review the presence of microbes that can contaminate the packaging, which can damage food or materials when using the packaging. The presence of contaminating microbes such as mold, Coliform yeast, Coliform and E. coli can come from new packaged products. Thus, the sample packaging is tested using the Colony counting method or Plate counting. by doing a swab on the test sample then dissolved and grown on the media. The medium is in the form of a petri film spreader in accordance with the microbes to be tested and then observed and the growth count is calculated. The microbes observed were Coliform, mold, and yeast as well as E. coli on flexible packaging and Coliform on standing pouch. After conducting the research, there was’n the type of microbe tested or zero and in accordance with the packaging industry company standards.

Abstract

Fruit jam is one of the preserved products that have a soft texture that contains crushed fruit and is mixed with sugar with the addition or without the addition of water. Preservatives are added to prevent damage to jams. A preservative that is usually added to jam is potassium sorbate. Potassium sorbate is commonly used as a preservative because it dissolves more easily when added to food. This study aims to determine the levels of potassium sorbate in jam samples. Potassium sorbate was determined using High Performance Liquid Chromatography (HPLC). From the test results, it was found that potassium sorbate levels ranged from719, 65 mg/kg to 757,24 mg/kg. The results of this test will be compared with the standards set by the Food and Drug Supervisory Agency (BPOM) No. 36 of 2013 concerning the maximum limit for the use of preservative food additives, namely 500 mg/kg. From the test results, it can be seen that the potassium sorbate in all samples exceeds the quality standard set by the BPOM. Therefore, people must be more careful in choosing jam to consume daily. The test results have used the right method, namely by adjusting the stationary phase, mobile phase and the right wavelength so that the% recovery results are 103%.

Abstract

Industrial wastewater is water from the processing of an industrial process. This type of water is classified as having poor quality because of the contaminants it contains. The contaminants contained in industrial water vary depending on the related processes that produced the water. This study aims to determine the concentrations of heavy metals Cu and Zn in industrial wastewater at three locations in Batam City. Wastewater testing was carried out using the ICP-AES. The results obtained indicate that the levels of Cu and Zn in the industrial wastewater samples at the three locations are still below the maximum concentration limit permitted by the Environmental Quality Standards and are in accordance with the Regulation of the Minister of Environment of the Republic of Indonesia No. 5 of 2014 Annex 47 About Wastewater Quality Standards.

Abstract

Cyanocobalmine is vitamin B12 which is widely used to treat or prevent deficiency (deficiency of vitamins) in various types of preparations. Cyanocobalmine in the 5th edition of Indonesian Pharmacopoeia literature can determine by UV-Vis Spectrophotometric method with water solvent. The purpose of this testing was to determine whether the levels of the active compound Cyanocobalamine from the 3 test parameters. In the description test where the sample tested is the same as the Cyanocobalamine specification, namely, crystal powder is dark red. Hot plate was used to determine drying shrinkage. Shrink drying was 2.25% - 2.75% from the ≤ 12% requirement. The determination of the levels of the active compound of Cyanocobalamine fulfills the requirements, namely 96% - 102.0%. The results of the assay showed that the average level of Cyanocobalamine from 4 samples was 96.02%, which met the standards set by the Pharmacopeia. Indonesia Edition V as a requirement for determining the levels of the active compound Cyanocobalamine.

Abstract

Indonesia is a country with the largest mangrove forests in the world. Indonesia also has various types of mangrove plants, one of which is pedada fruit (Sonneratia caseolaris). Pedada fruit is one type of mangrove whose fruit can be eaten. This fruit has good nutritional content and a source of vitamins A, B and C that are needed by the body. In addition, pedada fruit also contains phytochemical compounds that are closely related to antioxidant activity. With natural resources and abundant availability and nutrient content, pedada fruit is recommended to be used as processed food in order to increase food diversification. Pedada fruit has been processed into food processed products such as dodol, syrup, flour, ice cream, hard candy flavor, and jam. This study aims to study the characteristics of pedada fruit and its processed products into jam. Pedada fruit and jam have weak antioxidant activity values where the antioxidant activity is 549.91 ppm and 646.25 ppm, respectively.
