Abstract

 AbtracA study on the effect of total oil content on the epipelic diatom abundance were done in January to March 2018 in The Intertidal Zone of Kuala Tanjung Batubara District North Sumatera. Sediment samples were taken from 4 stations with different activities  and each stations was divided based on the intertidal zone (upper, middle, andlower). The result showed that total oil content the highest was station 4 (5377,1986 ppm)and the lowest was at station 2 (142,8497ppm).The highest abundance of epipelic diatom was found at station 2 (8933 ind/cm2).Epipelic diatom that were found in the intertidal zoneof Kuala Tanjung composing of 14 spesies. The total oil content in the intertidal zone was not different and total oil content between station was different. The epipelic diatom abundancein the intertidal zone was not differentand epipelic diatom abundance between station was different. Relationships between total oil content with epipelic diatom abundance in Kuala Tanjung were y= 7234,5 - 1570,7x; R2= 0,7432; r = 0,86. The oil content and epipelic diatom abundance has negative correlation, which means in creasing of oil content will cause a decrease the abundance of epipelic diatom in Kuala Tanjung. Keyword: In The Water of  Kuala Tanjung, Total Oil Content, Epipelic Diatom, Pollution

Abstract

Abstract Nygaard Index can be used to determined trophic state of waters. Calculation of this index is based on the number of phytoplankton species such as Chlrococcales, Centric diatom, Myxophyceae, Euglenaphyceae and Desmidiaceae. To understand the trophic state of the PLTA Koto Panjang reservoir waters, a research has been conducted in March - April 2018. There were three sampling stations, namely station 1 (an area with 100-150 floating cages), station 2 (an area with 200-300 floating cages) and station 3 (an area with 946 floating cages). In each station there were three sampling points, in the surface, 3.5 m depth, and 7 m depth. Sampling were conducted 3 times, once/week. Water quality parameter measured were phytoplankton, transparency, temperature, pH, nitrate, phosphate, Dissolved Oxygen and free carbon dioxide. Results shown that there were 82 species of phytoplankton present, namely Myxophyceae (19 species), Chlorococcales (28 species), Centric Diatom (15 species), Euglenaphyceae (1 species) and Desmidiaceae (19 species). The water quality parameters were as follows: transparency 108-138 cm, temperature 31-320C, Dissolved Oxygen 1.8-6.0 mg/L, free carbondioxide 13.8-29.5 mg/L, nitrate 0.07-0.131 mg/L, phosphate 0.15-0.36 mg/L. Nygaard Index value of the waters was 3.1-3.7, and it can be categorized as eutrophic.  Keywords : Koto Panjang Dam, Water quality, Phytoplankton, Eutrophic
