Abstract

Drinking water is the main need of humans as living things. Over time, humans are more practical so that for drinking needs they prefer to use bottled drinking water or refill drinking water. The high demand for bottled water raises the number of drinking water companies that issue bottled drinking water products. However, the quality of bottled water still needs to be assessed because it is not through pasteurization or other processing. So the microbiological content remains to be investigated. This study aimed to determine the bacteriological content in bottled drinking water. This study uses the Most Probable Number (MPN) method to test its bacterial content and gamma ray radiation to test its radiosensitivity. The sample in this study was bottled drinking water of various brands circulating in the City of Tasikmalaya. Based on the research results obtained from 13 samples there is 1 sample containing E. coli which is code B1 with a total bacterial content of 7 cells per 100 ml. So it can be concluded L samples are known to contain E. coli as much as 1.9 x 105 cells per ml.

Abstract

Contamination of processed beef foods such as abon can be caused by various types of microbes, one of which is Staphylococcus aureus. Staphylococcus aureus can cause various infections, both on the skin, gastrointestinal tract, or endocarditis. The objective of this research was to determine the presence of Staphylococcus aureus in beef abon sold in Pahing Market, Kediri. Abon used is non-branded beef abon which is as many as 10 samples obtained by total sampling technique. Samples were tested by observation of colony morphology through Gram staining, mannitol fermentation test, catalase and coagulase test, and acetoin test. The samples were inoculated on Broth NaCl (ink. 24 hour-37°C), then inoculated on MSA (ink. 24 hour-37°C), and VP (ink. 2x24 hours-37°C). Catalase and coagulase tests were carried out by taking colonies on MSA media. The results showed that there were 9 abon samples contaminated with Staphylococcus aureus as indicated by Gram positive staining results, positive (perfect) mannitol fermentation, and positive acetoin, catalase, and coagulase test. The causes of contamination are contaminated abon ingredients, the manufacturing process using less sterile tools, poor handling and processing, processing food with dirty hands, food stored without cover, sick food processors, and dirty markets

Abstract

Chromium metal is one of the heavy metal wastes from various industries and is persistent for the agricultural environment, especially in rice fields. Chromium metal can change biodiversity and ecosystem function in paddy soil. Chromium metal phytoremediation that pollutes paddy soils with hemp (Boehmeria nivea) is important because paddy soils play a role as a living medium for food crops, especially rice (Oryza sativa). One indicator of the success of phytoremediation is the reduction of chromium metal content in the soil, so it requires a policy system to maintain a healthy environmentally friendly agriculture. This study aimed to determine the ability of Boehmeria nivea to reduce levels of chromium metal in the soil and provide policy solutions to keep environmentally healthy agriculture. This study used a complete randomized block design, random sampling of chromium metal data. The results showed the initial concentration of chromium metal in the soil was 2.36 ppm, after treatment with the interaction between Agrobacterium sp. I3 with Boehmeria nivea (P0B1T1) and interaction of organic matter (compost) with Boehmeria nivea (P0B2T1) obtained Cr 1.37 ppm metal content with a decrease of 42.01%. The resulting policy solution is the Environment Health Agriculture System (EHAS). The conclusion of this study was phytoremediation of chromium metal using Boehmeria nivea combined with the Environment Health Agriculture System can create a healthy environmentally friendly agricultural system.

Abstract

The use of medicinal plants is increasing due to the lack of side effects caused and the number of bioactive compounds that cannot be represented by synthetic chemical synthesis compounds. However, the management and use of natural medicines for the main handling of diseases are often hampered by the quality of the ingredients which are low and unstable. The standardized quality control system of OAI (Indonesian Natural Medicine) is the main key to improve clinical assurance and safety of the use of herbal medicines in Indonesia. One of the medicinal plants known to the public is Curcuma longa L. (turmeric). The main active components contained in turmeric are curcumin, demetoksikurkumin, bis-demetoksikurkumin, and ar-turmeron. Information about the quality of turmeric is needed in its use as a raw material for drugs so we need an analytical technique that is able to identify the diversity of metabolite profiles of active compounds. In this research, an optimization method is used to improve efficiency in the extraction of turmeric rhizome metabolites so that the best solvent concentration is known for the analysis of fingerprinting secondary metabolites with 1H-NMR 500 MHz spectroscopy in turmeric rhizomes. The results were analyzed with MNOVA software and chemical shift obtained compared with the reference. From the results obtained a concentration of methanol-d4 (CD3OD) 100% able to extract curcumin better than other solvents. The solvent is able to extract saccharide (sugar) compounds in the form of sucrose, amino acids and fatty acids in the form of methionine, glutamine, acetate, and glycero phospho choline.
