Abstract

Clean and Healthy Lifestyle is essential to be endeavored by society for preventing variety of infectious diseases which one of the most common is dandruff or seborrhea sicca that caused by the growth of Pityrosporum ovale fungi. This research is indicated to provide a better alternative option using ingredient given by nature that can treat dandruff. This research using banana peel extract since it is an original fruit from North Sumatra. The result from phytochemical screening of the banana peel extract shows secondary metabolites which are saponin, tannin, steroid/tritepenoida, flavonoid and glycosides. To produce barangan banana peel extract is by maseration method. Antifungal activity test using barangan banana peel extract towards Pityrosporum ovale is done by disc diffusion method. The antifungal activity test shows the biggest result for Minimum Inhibitory Concentration (MIC) extraction concentration at 1000 mg/ml with the average diameter of 11,9 mm. According to the inhibitory scale of antifungal activity test of barangan banana peel extract towards the growth of Pityrosporum ovale is ineffective.

Abstract

Joint waste management between regions that bordered each other can be one alternative solution of the problem of trash in Indonesia. Some areas have conducted cooperation in waste management, such as Sarbagita and Kartamantul. Dynamic game can be an alternative method in joint waste management between the regions. The purpose of this article is to design joint waste management between regions using the dynamic game theory framework approach. A dynamic game is a mathematical model that represents the conflict situation between the interested parties who want to make the best decision (in this case it is the city/district government) of a series of strategies that are possible by considering the existence of the various uncertainties at such situation. The discussion is done by assuming there are three areas of the bordering regoins and making some waste disposal regulations. Furthermore, the mathematical operations and simplification of the form of equation are executed to adapt to the design objectives. The results of the design in this approach are the invention of two mathematical equations describing the characteristics of dynamics waste stock in the adjoining regoins, and the cost to be incurred by each regions in managing its waste stock.

Abstract

The research was conducted to observe the effect of Allium cepa L in reducing blood glucose level in white rat (Rattus novergicus). Treatments were consist of 2 ml and 4 ml of Allium cepa L and aquadest was used as treatment for control group. The result showed significant effect of both treatments using Allium cepa L compared to control group. Thus concluded that Allium cepa L has a good efficacy in reducing blood glucose level. But posthoc test using LSD did not show any difference between treatment groups of 2 ml and 4 ml.

Abstract

The aim of this study was to assess the percentage of local duck spermatozoa morphology (Anas platyrhynchos) for 6 days of storage in three storage mediums combining various egg yolk (EY) concentrations.This experimental study applied three combinations of factors as treatment. Medium (Tris, PBS or Ringer lactate), egg yolk (EY) concentration 0,5,10,15 or 25% and storage time (0,1,2,3,4,5,6 day). Spermatozoa obtained by sequence method, ejaculate or sperm obtained in swim up in medium, swim up spermatozoa were used for treatment in storage medium according to treatment and assessed before and after morphology of storage in refrigerator temperature (50 C). The results showed that spermatoza morphology was significantly different (P <0.01) between 15 treatments. The medium factor and concentration of EY significantly (P <0.05) affected the morphology of treatment spermatozoa. The highest percentage of highest post-preservation spermatozoa morphology for six days was obtained in 5% yolk treatment in PBS medium (5EYPBS). This study proves that egg yolk cryoprotectants are good for maintaining the morphology of local duck spermatozoa.

Abstract

The aimed of this research was to investigated human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri), to investigated dose of tartrazine, and to investigated biotransformation of tartrazine by human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). The method of this research was experiment with significant correlation to investigated biotransformation of tartrazine by human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). This study is primarily focussed on made bacteria medium, made standart inoculums of bacteria, and evaluation for activity of human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). The results obtained were attributed to the human intestinal bacteria was used in this research was biotransformated tartrazine. From the results that had been increase dose of tartrazine correlation with increase biotransformation by human intestinal bacteria. Highest dose of tartrazine was 15 mg, and highest biotransformation by Vibrio fischeri, which rate of zone decolourisation diameter was 1,22 cm, and rate of zone decolourisation was 1,44 cm2. Statistically showed significantly in correlation dose of tartrazine with rate of zone decolourisation (0,001 &lt; P &lt; 0,05), but statistically showed non significantly in correlation bacteria with rate of zone decolourisation (0,05 &lt; P &lt; 0,268).

Abstract

This reseach was conducted to determine the antibacterial activity against Staphylococcus aureus and Eschericia coli from pandanus fragrant ethanol extract formulated in the form of hand gel antiseptic preparations. The ethanol extract was prepared by percolation using 96% ethanol solvent. Phytochemical screening is done on fragrant pandan leaves. Evaluation of hand antiseptic gel preparations included organoleptic testing, homogeneity testing, pH determination, spreading test, stability, irritation testing and antibacterial testing of Staphylococcus aureus and Eschericia coli. The results of phytochemical screening showed that the pandanus fragrant leaves contain alkaloids, tannins, saponins, flavonoids and polyphenols. The pandanus fragrant leaves ethanol extract can be formulated into hand gel antiseptic preparations because the pH is about 6.0-7.1, the spreading power is about 5.06-5.15 cm, stable for 12 weeks and organoleptically a formula with a very 2.5% concentration Favored and does not irritate the skin. The results of antibacterial activity test showed that the preparation with concentration of 10% had the strongest activity with the diameter of 13,23 mm to Staphylococcus aureus and 13,13% to Eschericia coli almost same with dettol stock on the market with diameter 16,43mm to Staphylococcus aureus and 16 , 03% against Eschericia coli.

Abstract

This reseach aims to determine the relationship between obesity and blood lipid levels in patients who seek treatment at Hospital Haji Medan. The research uses descriptive method that is a picture of the number of people to pull data directly from secondary data sources, namely the medical records of all patients treated at the Hospital Haji Medan. Parameters measured were patient age, sex and analyzing the increasing number of patients from 2012 to 2013. The results showed that the samples of patients who are obese biggest is 41-60 year age range that is equal to 44.15%, normal conditions alone amounted to 25. 98%. The second age range who are obese in this study were 61-80 years is 11.04% and normal as much as 8.44 percent, and the third at 21-40 years of age as much as 1.95 obesity and 8.44% for normal conditions , obesity among men and women obtained the highest percentage calculations for obesity is on the female is 46.75% while the male percentage of 13.64%. Obesity  patients have cholesterol levels &gt; 200 for a total percentage of 48.05%, while patients with normal conditions of 9.09%. Based on the age of the highest number of obese in the age group 41-60 years, while based on gender, obese women more than men.
