Abstract

This study was conducted in July 2013 in the coastal waters of Beruk Island, Riau. This study was aimed to describe the species composition, distribution, density of seagrass and gastropods, its was also directed to know the distribution of gastropods based on the distribution of seagrass. The survey methods was used in this study. The results showed that there were 279 individuals of gastropod. Those consisted of six species, i.e. Strombus urceus, Ellobium sp, Nerita costata, Conus nobilis, Littorina sp, and Gibbula ardens. There were two seagrass species used as habitat by gastropod, i.e. Enhalus acoroides and Halophila ovalis. Distribution patterns of gastropods in Beruk Island were generally uniform, and varied at each station. The analysis showed that C. nobilis found at all stations, this indicated that these waters were suitable for the survival of C. nobilis, as well as the seagrass species of E. acoroides was also found in all stations.Keywords: Asosiasi, Gastropoda, Padang Lamun, Pulau Beruk

Abstract

A study on the accumulation of heavy metal by mangrove in Batam coastal waters was conducted in February 2014 by analyzing the concentration of heavy metals of Pb, Cu, and Zn in the roots, trunk, leaves and fruit of A. marina growing in the industrial and non- industrial areas. Survey method was applied at 4 stations with 3 replications each. The results showed that the highest concentration of Pb in A. marina was found in the fruit (4.47 μg/g) and the lowest was in the trunk (3.96 μg/g). The highest concentration of Cu in the roots of A. marina was 8.47 μg/g and lowest was in the leaves 7.88 μg/g. While the highest Zn concentrations in A. marina was identified in the trunk (36.69 μg/g) and the lowest was in the roots (34.99 μg/g). The concentrations of Pb, Cu and Zn in non-industrial region ware higher than that in the industrial area, but statistically they were not significantly different (p > 0.05) for Pb and Cu, it was significantly different (p < 0.05) for Zn.Keywords : Avicennia marina, heavy metals, shipbuilding industry, Batam Island

Abstract

This study was carried out in February 2014, with the aim to analyze the oilcontent during high and low tide in the different area in coastal waters aroundGunungsitoli Port of Nias Regency. This study was expected to serve as the initialinformation about the content and distribution of oil in the water and can be used as areference in reviewing the environmental conditions in the waters of GunungsitoliPort of Nias Regency. The results showed that the average oil content was 0.256 ppmat high tide and 0.193 ppm at low tide. The average oil content was not significant bydefferent (p > 0.05) betweel high and low tide. The oil content during high tide basedon the distance from the beach were as follow : 0.281 ppm near the beach, 0.273 ppmin te middle and 0.214 ppm in auter coastal. Meanwhile during the low tide the oilcontent were 0.0234 ppm at the beach, 0.174 ppm in the middle, and 0.172 ppm inthe auter coastal, respectively. Based on the distance from shore oil content showedno significant difference (p > 0.05). Oil content in the port / area was 0.288 ppm, intourist areas / settlement, 0.237 ppm, and in the Depo Pertamina was 0.244 ppm andthey showed no significant diffrence (p > 0.05).Keywords: Oil Content, Tidal, Gunungsitoli Port.

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 study was conducted in June 2013. The study aim was to the determine the diversityof gastropods in the intertidal zone of Cingkuak Island and Pasumpahan Island. Survey methodwas used to collect information related to the purpose of the study. There were 2 stations chosenalong Cingkuak Island and Pasumpahan Island. For each station there were 3 transects, whichhave 5 plot for every transect, were employed. Sample of gastropods were transported to thelaboratory for identification, counting of the individual number, and calculation of the value ofdiversity index, dominance index and equibility index.The results showed that there were 164 individual gastropods at Cingkuak Island and 90individual gastropods at Pasumpahan Island. The gastropods were comprised of 4 orders, 4families and 16 species. The most dominant species founded in Cingkuak Island andPasumpahan Island were Littoraria intermedia and Littorina vespacea. The value of diversityindex at Cingkuak Island was high and at Pasumpahan Island was medium. Value of equabilityindex was medium. Value of dominance index at Cingkuak Island and Pasumpahan Island waslow. The habitat of gastropods still supported and considered safe for macrozoobhenticorganism.Keywords: Diversity, Gastropods, Cingkuak Island, Pasumpahan Island

Abstract

Dinoflagellate is a group of monocelullar microalga prossesing of double flagel. This organism can be found in a subtropic and also in a tropic marine water. Some potentially toxic epibentic dinoflagellate assemblage with macroalgae and potentially to cause blooming such as Gambierdiscus sp, Ostereopsis sp and Prorocentrum sp. Blooming of this population can generate "Red Tide". This reaserch was aimed to understand about dinoflagellate abundance of Gambierdiscus sp, Ostereopsis sp and Prorocentrum sp at Nirwana Beach, West Sumatera. The method used was a survey method. Sampling was done by cutting the seagrass stands, and from the stand taken three leaves and then stored in plastic bags containing clean sea waters. The dinoflagellates were separated from seagrass leaves by shaking in a plastic bags. And then filtered with 135μm and 20 μm respectively. Dinoflagellate then observed on a Sedgewick Rafter Cell under a microscope. The results showed that the highest abundance of dinoflagellate on Thalassia sp found at station 1 (132 cell/g leaf). The lowest abundance occurred at station 3 (69 cell/g leaf), which close to mangrove area. The most abundance of all species was Prorocentrum sp, while the lowest abundance cell was Gambierdiscus sp.Key word: Dinoflagellate, Abundance, Seagrass, West Sumatera
