Abstract

Clean water is a serious problem in Indonesia, the availability of clean water has shrunk drastically due to deteriorating environment and pollution. Drinking water that meets safety standards is increasingly scarce. More than 100 million people need safe water sources. Filter media is able to remove chemicals in water such as turbid, odor, oily, yellowish, rusty and muddy making it unfit for consumption. In addition, the purpose of the clarification results must also be considered whether to drink household needs or other needs. This study uses Lauryl Tryptose Broth (LTB) media and petrifilm media. Petrifilm results show that it is very easy to count the bacteria Colifrom and Escerichia coli using petrifilm media. From the analysis of calculations using the Paired Samples T-Test on the sample before filtering and after filtering it was obtained the Tcount value of 2.28 with a P value 0.015 which showed very successful or significant results between the samples before and after the filter. In this analysis have normally distributed data with a significant value of P = 0.015 (<0.05). In this case the Paired Samples T-Test was tested for normality (Shapiro-Wilk) and the results were obtained in the form of a P value of <.001 which would indicate that the data was normally distributed, indicated by a P value <0.05. The filter on this filter is very useful for filtering on Escerichia coli bacteria because this filter removes the bacteria, but Colifrom bacteria can still escape the use of the filter, because it depends on environmental conditions. Colifrom and Escerichia coli bacteria occur is seen from the relationship between sources of pollution such as, for example, such as septic tanks, distance of wells with waste, trash, and livestock pollution. The quality of drinking water is very close to the presence of Colifrom and Escerichia coli bacteria which are likely to have pathogenic bacteria that are harmful to health in the quality of well water. Water samples to be observed using well water using 2 treatments as many as 12 repetitions. Thus the total sample obtained as many as 24 water samples will be observed. While the test making of Lauryl Triptose Broth medium was observed by incubating 48 hours at 35oC + gas. Before making the test tube medium must be sterilized first. Subsequent tests were observed with a petrifilm medium to determine the presence or absence of Colifrom and Escherichia coli bacteria by looking at the color of the battery being sought.

Abstract

ABSTRACT As a maritime country with vast waters, Indonesia has many opportunities to utilize marine resources as a source of bioactive compounds that have the potential as active medicinal ingredients. One of the marine biotas that potentially contains the active compounds is the Vannamei shrimp's shell (Litopenaeus vannamei), which is commonly found as waste along the coast of Gunungkidul, Yogyakarta. The shrimp’s shell contains astaxanthin, a potential source of antioxidants for the health industry. The purpose of this study was to compare the astaxanthin extraction yield from L. vannamei shrimp shells using sunflower oil and 70% ethanol. The Astaxanthin extraction used sunflower oil and ethanol 70% as solvents and was done by maceration method, while the phytochemical test and Astaxanthin profiling used Thin Layer Chromatography and Spectrophotometer with Kelly and Harmon (1972) [5] calculations as well as pure Astaxanthin standards. The extraction yield of the 70% ethanol extraction was further processed by column chromatography using ether: ethanol (8: 2) as mobile phase. The highest Astaxanthin yield (220 mg / g of shrimp powder) was obtained from the extraction with sunflower oil compared to the 70% ethanol solvent, while the fractionation result with a chromatographic column from a crude extract of ethanol 70% showed high astaxanthin yield of 220.77 mg. / g fraction. The results of the fraction test on rat neutrophils, the best percentage reduction was at a concentration of 150 mg / g bw of rats.

Abstract

Various kinds of agricultural products are needed to support organic farms to produce superior quality products, one of it was natural herbicides. Some plants have the potential to become natural herbicides by producing chemical compounds, namely allelopathy which can inhibit the growth of surrounding plants and Murraya keonigii is one of it. This study aims to see the potential of M. keonigii to become a natural herbicide. Grass seeds were given M keonigii’s extract at a dose of 0 gr / l (control / M0), 50 gr / lt (M1), 60 gr / lt (M2), and 70 gr / lt (M3). The results showed that the aromatic or allelopathic compounds in M ​​keonigii affected the germination. Germination was slower at doses of 60 gr / l (M2) and 70 gr / lt (M3) compared to controls (M0) and 50 gr / lt (M1). Radicle length did not increase rapidly in M2 and M3 treatment. Germination power of grass seeds in control and M0 had a value of 100% or all germinated, while M1 and M2 had 67% germination. The higher the dose of M keonigii extract, the slower the process of grass seed germination.

Abstract

The formulation and physical characterization test of rosella extract cream preparations have been carried out using various types of non-ionic emulsifier concentration ratios (combination of tween 80 and span 80). Comparison of the concentrations of tween 80 and span 80 used in this study were 2%, 3%, and 4%. The aim of this study included organoleptic test, homogeneity test, pH test, viscosity test, dispersion test, and emulsion type test. The result obtained from the physical characterization test were the organoleptic tests for the three formulas showed the same organoleptic results, namely red color, characteristic smell of rosella, and semisolid consistency. Homogeinity test shows that the formula is homogenous. The pH test showed that F1 4,29; F2 4,6; F3 5. Viscosity test showed that F1 432,4 mPas; F2 434,3 mPas; 435,3 mPas. The dispersion test was carried out without using a load of 50 g, 100 g, and 200 g. the results shown form the spreadability test of three formulas were were F1 5 cm; 5,5 cm; and 6 cm; F2 6 cm; 6,35 cm; 7,25; and 7,5 cm. F3 6,25 cm; 7,5 cm; 7,75 cm; 8 cm. The emulsion type indicated by the three formulas is oil in water. Based on these results, it can be seen that the emulsifier concentration has an effect on PH, viscosity, and spreadibility. The higher the concentration of emulsifier used, the higher pH value, viscosity, and spreadibility.
