Abstract

Hypercholesterolemia is a condition where cholesterol levels in the blood exceed normal limits and are a cause of risk of coronary heart disease. Generaly hypercholesterolemia occurs in old age but does not rule out the possibility that it can occur in adolescence. The purpose of this study was to determine the prevalence of hypercholesterolemia in adoles­cent patients in the Thamrin clinical laboratory in Medan 2017. This study was conducted in June 2018 with descriptive methods obtained by collecting secondary nomina from the results of the patient's laboratory examination. Based on the results of the study of the prevalence of hypercholesterolemia that occurred in adolescents as many as 123 people with a percentage of 17.7% of the number of adolescent patients who visited. The conclusion of this study is the state of hypercholesterolemia can occur in adolescents not only in adulthood and old age.

Abstract

Manilkara zapota L was included plant which the most popular in South East of Asian. The society also used young fruit, bark, and Sapilla Manila Leaf as tradisional medicine diaerrhea resistant, because substance of tanin was contained in it could hampered and killed the number of bacterias such as Shigella, Salmonella thypii, Escherichia coli. This research purposed for knowing ability of blocked energy from exstract Sapilla Manila Leaf towards Escherichia coli. This research experimentalsm with used qualitatif methode and diffusion methode. Concentration extract of  Sapilla Manila Leaf which was used namely 5%, 10%, 15%, 20% with 5 times,. The result of research showed that extract Sapilla Manila Leaf with each that concentrat have not hampered growth of Escherichia coli. The possibility was caused by several factors such as the concentration level of the extract, the nature of the bacteria used and the tools used in the solvent evaporation process.

Abstract

The purpose of this research was to determine the ability of BAL from cattle intestine (Bos taurus) in inhibiting the growth of Eschericia coli and Shigella sp. Testing of BAL capability in inhibiting growth of Escherichia coli and Shigella sp. using the disc-diffusion method or the Kirby-Bauer method, which was done by measuring the inhibit zone around the paper disc. Data were analyzed descriptively by displaying data in table and picture form. The results obtained 2 isolates of BAL from the cow intestine. All isolates showed positive results when tested for antibacterial against Escherichia coli and Shigella sp. In isolate BAL with code sp1 has inhibition zone against Escherichia coli equal to 7.5 mm and to Shigella sp. of 6.8 mm, whereas in isolate BAL with code sp2 has inhibition zone against Escherichia coli equal to 8.9 mm and to Shigella sp. of 8.0 mm. Based on the results obtained, it can be concluded that isolates of lactic acid bacteria with sp2 code has inhibition zone 8.9 mm in inhibiting Eschericia coli while against bacteria Shigella sp. has a diameter of 8.0 mm.

Abstract

Sunflowers ((Helianthus annuus L) is a plant that has the ability to absorb metals in polluted soil or environment. This study aims to determine the ability of sunflower plants to absorb lead (Pb) in the soil. This research method use a Completely Randomized Design (CRD). Pb metal analysis was carried out by testing the lrvels using the Atomic Absorption Spectrophotometry (AAS) tool in the Chemical Laboratory (LABKES). The results showed that the highest absorption of Pb contamination in P2L2 treatment (2.0 ppm) as much as 5.04 ppm and the lowest absorption of metals in the treatment P1L1 (0.3 ppm) yielded as much as 0.52 ppm Pb metal content. From the results of these studies it can be concluded that sunflower plants can be used as phytoremediation pf Pb metal.

Abstract

The purpose of this study was to reduce the levels of ammonia (NH3) and phosphate (PO4) in water hyacinth (Eichornia crassipes) experimentally with contact times with water hyacinth 24 hours, 48 hours and 72 hours. Water hyacinth has 2 plants, 4 plants, 6 plants and 1 control bucket. From the results of this study, the contact time of 24 hours can reduce ammonia levels by 46% - 82% and phosphate content by 33% - 56%. The ammonia content can be reduced by 71% - 87%, the phosphate content by 58% - 90% with a contact time of 48 hours, and the ammonia content can be reduced by 89% - 91% with a contact time of 72 hours. . Phosphate content 82%-97%. The maximum absorption time is 24 hours of contact time. This is because the ammonia content can be reduced by 46% - 82% and the phosphate content can be reduced by 33% - 56%.

Abstract

Worm disease is still one of the health problems in Indonesia. Personal hygiene such as playing in the school ditch, on the ground, playing dirty and some children do not use footwear, long nails and the habit of not washing their hands with soap before and after playing, thereby increasing the risk of intestinal worms in children. This study aims to determine the percentage and types of intestinal nematode worm eggs that infect elementary school children grades 1 and 2 Raudathul Jannah Foundation, Penraujan Private Elementary School, Sunggal District, Deli Serdang Regency. The method used in this study was direct stool examination. Based on the results of the examination of 48 samples of elementary school students in grades 1 and 2, it was found that 3 samples were positively infected with intestinal nematode worm eggs with a percentage of 6.25% and there were 2 types of worm eggs that infect, namely Ascaris lumbricoides and Trichuris trichiura. Where sample (S 12) was infected with Trichuris trichiura worm eggs, sample (S 37) was infected with Ascaris lumbricoides worm eggs and sample (S 46) was infected with both types of worm eggs, namely Ascaris lumbricoides and Trichuris trichiura.

Abstract

Penelitian ini bertujuan untuk mendapatkan isolat bakteri endofit dari akar cabai merah Capsicum annuum dan mengetahui kemampuannya dalam menghambat pertumbuhan jamur patogen Fusarium oxysporum. Penelitian ini menggunakan metode deskriptif berskala laboratorium. Hasil isolasi dari akar cabai merah Capsicum annuum ditemukan dua koloni isolat yang berbeda yang diberi dengan kode isolat A1 dan A2. Kedua isolat bakteri endofit diduga merupakan genus Bacillus. Hasil daya antagonis kedua isolat menyatakan bahwa bakteri endofit tersebut mampu menghambat pertumbuhan jamur patogen Fusarium oxysporum, hal ini dapat dilihat dari diameter zona hambat yang terbentuk.

Abstract

Dermatophytes are a group of fungi that cause nail abnormalities. This study aims to determine dermatophyte fungal infections in patients with nail mycoses. The method used in this study is descriptive and the sample was taken by purposive sampling with the criteria of damaged toenails, with characteristics: nails are not shiny, brownish to black from the base to the tip then the nails are examined directly with 10% KOH and cultured using media Sabouraud Dextrose Agar (SDA). The fungi isolated on slanted agar containing SDA and each fungal species were then identified using preparations for microscopic examination. The results showed that from 30 samples, 8 (eight) nail samples were positive for dermatophytes, namely: 5 (five) people infected with the fungus Tricophyton mentagrophytes species, 2 (two) people infected with the Trichophyton rubrum fungus, and 1 (one) person infected with Epidermophyton floccosum..
