Abstract

Oil degradation bacteria can be found in various habitats in the marine environment including in the waters around the harbor. This study aims to isolate the oil degrading bacteria from waters around the port of Bengkalis and test its ability to degrade crude oil. Isolation of the degrading bacteria has been done from February to April 2017 at the Marine Microbiology Laboratory, Department of Marine Science, Faculty of Fish-eries and Marine University of Riau. The amount of oil degrading bacteria ranges from 0.2 x 105 to 8.9 x 105 CFU/ml. The isolation result was obtained by 10 isolates of oil degradation bacteria, ie BM1a, BM1b, BM1c, BM1d, BM7a, BM7b, BM7c, BM7d, BM14a and BM14b. Identification based on morphological, physiological and bio-chemical characteristics of each isolate, all isolates were round and elevated, six were white in color, three were yellow, one cream-colored isolate, eight isolates with slip-pery edges and two isolates with periphery waves, seven isolates were indol positive, two isolates produced H2S, four isolates were methyl red positive, all isolates were motile, capable of fermentation of glucose and sucrose in sugar test, able to ferment citrate, positive catalase and Gram negative bacteria. For degradation test only five bacterial isolates were selected of BM1a, BM1b, BM1c, BM7a and BM7d. The highest degradation at 1% concentration was indicated by isolate BM1a, the highest degrada-tion at 2% and 3% concentrations was indicated by BM1c isolate. Therefor, bacteria isolate capable of degrading the highest crude oil was BM1c.

Abstract

The research was conducted in May 2014 in Medan Kota Belawan coastal waters. The aim of this research was to analyze the oil contents and diatom abundance as well as their correlation during high and low tide. Samples of sea water for oil and diatom analysis were collected from 4 stations. The analysis of oil content as well as identification and quantification of diatom were carried out in Marine Chemistry Laboratory, Faculty of Fisheries and Marine Sciences, University of Riau in Pekanbaru. The results of the study showed that the highest oil content was found during the high tide in Station 1 (0.322 ppm) and the lowest was at Station 4 (0.040 ppm). Diatoms that were found in the surface waters of Medan Kota Belawan coastal water comprising of 18 species. Nitzschia scrianata was the species with the highest abundance (3640.73 cells/l). The diatom abundance was found to be highest during high tide in Station 4 (1213.58 cells/l) and the lowest was during low tide in Station 1 (360.80 cells/l). Oil content with diatom abundance showed a weak negative correlation (Y = 639,7-971,1x ; R2 = 0.146 ; r = 0.382) at high tide while at low tide Y = 520.7-1370.0x ; R2 = 0.115 ; r = 0.339 which mean that increasing oil content will decrease the abundance of diatoms in Medan Kota Belawan coastal waters.Keywords : Belawan Coastal Waters, oil, diatoms and tide

Abstract

This research was conducted in June 2015 with the aim was to knowing the concentration of heavy metals of Pb, Cu and Zn accumulated in the albumen and yolk of olive ridley sea turtle (Lepidochelys olivacea) from Pariaman town beach, West Sumatra Province. The method used was a survey conducted on 3 beaches. The results showed that the average metal Pb in albumen (2.7644 μg/g) was greater than the metal Cu (2.0970 μg/g) and smaller than the metal Zn (10.4924 μg/g). While metal Pb in yolk (6.8008 μg/g) was smaller than the metal Cu (7.0357 μg/g) and metal Zn (34.1479 μg/g). The PTWI calculation value (the Provisional Torelable Weekly Intake) based on FAO/WHO standard for an adult weighing of 70 kg told that the eggs were still reasonably consumtable as long as it did not exceed the limit of 3.2932 kg/week for Pb, 482.8780 kg/week for Cu and 197.5793 kg/week for Zn. However, consumsing turtle eggs continuously can harm the body’s health and threaten the sustainability of turtles in the wild.
