Abstract

This research was conducted to determine the species diversity of macrozoobenthos and determine the condition of physical and chemical factors in the waters of estuary river in  Nipah Village Perbaungan District Serdang Bedagai Sumatera Utara. The result of diversity of macrozoobenthos obtained 28 species with one phylum, 2 class, 7 orders, 18 families and 20 genera. Measurement of physical and chemical factors waters obtained an average pH 7 both ebb and tide conditions; in conditions of salinity waters receded an average of 0 and at high tide the average of 5; the ebb and tide conditions an average temperature of 27-30°C; Average current speed 10,5-19,1 cm/s; Brightness average water 14-16,3cm; and an average depth of 40,3-150cm. Values obtained by the abundance of species which are 3378-5322 ind/m2. Macrozoobenthos types that dominate the river mouth Nipah are gastropods. Values Diversity Index (H ) macrozoobenthos of 2.152 to 2.762 were classified into well water. Uniformity index (E) showed a value of 0.397 to 0.532 (deployment is not uniform or uneven). Value Dominance Index (C) showed a value of 0.074 to 0.170 (the dominance of low or no kind dominance). In general, relatively good water conditions and suitable for life macrozoobenthos.

Abstract

The purpose of this research was to determine whether there is a relationship of senile cataract with blood sugar levels for people with diabetes who checked in BKIM (Balai Kesehatan Indera Masyarakat) Medan. Research was done through two stages, blood sampling and examination of blood glucose levels and data analysis. The patients blood is taken at any time from the patients fingertip. Data were analyzed calculated the correlation relationship where the cataract as the parameters x and y are the blood sugar levels. Correlation calculation results indicate the number r = 0:46, which means there is less close relationship between cataracts and blood sugar levels but percentages show increased in the percent of patients with both cataracts relation to blood sugar levels as well as cataracts with age. From a study of 60 patients aged 45-65 years who suffer from cataracts are less significant association between cataract with blood sugar levels.

Abstract

This research was conducted to determine the type of substrate and its composition in Kampung Nipah ecosystems Perbaungan Serdang Bedagai District of North Sumatra in February to March 2016. Sampling by using the pipe with descriptive methods  and the purposive random sampling technique, while the measured variable is the biology variables that includes physical and chemical factors waters. Physical and chemical factors include pH, salinity, temperature. The study of these types of substrates include gravel, sand is very coarse, coarse sand, medium sand, fine sand, very fine sand, silt and clay. Measurement of physical and chemical factors waters obtained an average pH 7 both estuaries, mangrove rehabilitation and natural; salinity of estuarine waters at 200/00 and the rehabilitation of 280/00 natural mangrove 240/00; average temperature of 29-30°C. At the mouth of the river, gravel 0.95%, 97.56% sand and mud of 1.58%, obtained ma sand and mud of 1.58%, obtained mangrove rehabilitation of gravel 0.16%, 93.53% sand, and mud 6.12%, while the natural mangrove 0% gravel, sand 29.88%, 69.89% and mud. So we get the type of substrate on river estuaries nypa and mangrove rehabilitation is the sandy substrate and on a natural mangrove is a muddy substrate.

Abstract

This study aims to identify the types of fungi that infect skin toddler patients at the General Hospital Haji Adam Malik Medan. The study was conducted by descriptive method using examination observation fungi on skin scrapingssuffering from infection with a total of 30 samples. Examination was performed using 10% KOH and fungal culture media Sabouraud Dextrose Agar  and incubated at room temperature (25-30oC). Based on the results of this study concluded that the type of fungus that infects the skin of patients under five years old are Trichophytonrubrum, Microsporummgypseum, Epidermiophytonfloccosum, Candida albicans and Candida tropicalis.

Abstract

Research on the community structure of macrozoobenthos in the area of mangrove rehabilitation and mangrove naturally in Kampung Nipah Bedagai Serdang, North Sumatra was aim to determined the community structure of macrozoobenthos with the inventory and identification of the types of macrozoobenthos at the sites. The method used in this research is descriptive method by determining and manufacture of sampling points with purposive sampling method. The results showed that macrozoobenthos were found grouped in three classes of Bivalves, Gastropods, and Polychaeta with the total number of individuals as much as 775 individuals. Group class that has the number of families and the highest number of species are Gastropods (19 families and 29 species), followed by Bivalves (6 families and 13 species). Polychaeta only has one family and one spesies. Diversity index (H ) of the study sites showed a value of 2.37 with the medium category. Value uniformity among the sites is 0,63 which means that the distribution of individuals of each type tends to evenly at each station and observation points.
