Abstract

This research was conducted on June 2009, located in Estuary Kampar Rivers, Pelalawan Regency, Riau Province. It was aimed to understand study andanalyze the characteristics of the sediment and the possible applicability in the Kampar River Estuary. Results of laboratory analysis of sediment samples obtainedgrain size distribution of five types of sediment texture, namely: sand, sand silt,sandy silt, silt, and sandy mud. Heavy mineral analysis of heavy minerals obtained 9,3 light mineral, and clay minerals. Heavy minerals obtained in the form of magnetite,kasiterit, zircon, tourmalin, pyrite, amfibole, ilmenite markasit, and pyroxene,whereas for minor minerals, namely quartz, muscovite, and biotite. Chemicalanalysis of sediment samples obtained rare earth elements, such as tantalum, ytrium,zirconium, and content kasiterit associated with other minerals.Key words : Sediment, Sand, Bono

Abstract

This research was conducted in May 2009, in the waters of Muara Aek Tolang Pandan Central Tapanuli of North Sumatra Province. The purpose of this study wasto map the distribution pattern of nitrate and nitrite content and O2 content (DO)dissolved in the mouth of the river Aek tolang horizontally. The method used in thisresearch was survey method. The primary data obtained from direct measurementsand sampling directly in the field and then tabulated and analyzed in the laboratoryare discussed further in descriptive, while secondary data related to research obtainedfrom the relevant authorities. spreading pattern of Nitrate and Nitrite concentrationdistribution was influenced by tides and currents. It can be seen by the differences inconcentration at the surface and ground waters at high tide and low tide at the samestation point. At the time of ups and downs have a much different variations on eachstation. The concentration of dissolved O2 measurements conducted at research sitesat high tide waters ranged from 111.6 ppt - 442.3 ppt. Based on measurements takenin Coastal Estuary Aek Tolang Pandan then the quality of waters in the study area nogood.Keywords: Nitrate and nitrite content, O2 content (DO)dissolved, Spreading

Abstract

The research was conducted on Date December 17, 2013 - December 31, 2013 in the waters of the island located in the District Augments Stimulation Meranti Islands Regency of Riau Province. Sustains Island coastal region is an area that is affected by tides and waves, where one result of the magnitude of wave and tidal current that goes to the beach cause some physical damage such as: land erosion (abrasion) in these coastal waters. The purpose of this study was to measure the speed and direction of currents, determine the type of tides, tidal currents describe Sustains Island waters, with the known velocity tidal currents, it can be seen that the damage resulted in changes in beach profile shape. The method used in this study is a survey method. On the island waters Sustains the above calculation, the average difference between the position of the high water and low water Sustains Island is 415.7 cm and the average position of the lowest water is 86.9 cm, high-elevation curves portray the sea water level. Type Sustains Island tidal tidal Sustains Island-type mix with prominent double type.     Keywords: Water Sustains Island, Oceanographic Studies

Abstract

The study was conducted in May-June 2015 in Berhala Island and its surrounding waters. The aim of this study was to know the marine ecotourism potential in Berhala Island as marine ecotourism destination in the future. The method used in this study was a survey method. The data observed consist of exploration results and inventory attractions, respondents of tourist representation and in situ measurement of water quality parameters. Berhala Island had huge potential of marine ecotourism and has a tremendous opportunity to be developed as a marine ecotourism region. It was shown on the suitability of marine ecotourism development, both assessed based on the criteria of supporting tour, SWOT analysis, calculation the value of WTA and WTP to the calculation of potential economic value . The potential economic value of marine tourism in Berhala Island is Rp. 52,159,000 (in the agenda of the annual holiday). This value was sufficient with still lack of facilities in the Berhala Island and potentially will grow if there are a implementation of the construction and development in Berhala Island region in the future.Key Word: Potential, Marine Ecotourism, Berhala Island

Abstract

This research was conducted in December 2013 in the intertidal zone of Topang Island of Meranti Islands regency in Riau Province. This study aims was to determine the community structure of the intertidal zone macrozoobenthos in Topang Island. The method used was a survey to determine the location of the study which consisted of 7 and 3 point sampling station. Macrozoobenthos samples were taken and analyzed in a laboratory of marine biology.The result showed that, the macrozoobenthos in the study site consisted of 18 species belonging to 4 classes. Macrozoobenthos density in the study area varies where the station the highest was of stastion two (II), and the lowest at station VI. Based on the value of diversity index (H ') macrozoobenthos in the study area were at moderate meaning no dominant species and the distribution was at uniformity.Key Words : Intertidal Zone, Macrozoobenthos, Structure Community

Abstract

Ciguatera Fish Poisoning (CFP), can be caused by ciguatoxin from groups such as the bhentic dinoflagellate of Gambierdiscus sp., Ostreopsis sp., and Prorocentrum sp.,the bhentic dinoflagellates potentially toxic. In addition as bhentic organisms these three bhenthic dinoflagellates also found associated with brown algae, red algae, coral fragments and also attached on seaweed . Research on the distribution of the toxic dinoflagellate benthic Sargassum sp in the coastal waters of Sungai Nipah Beach of Pesisir Selatan Regency of West Sumatra Province was conducted in April 2014 with the to analyze the abundance and distribution of benthic dinoflagellate Gambierdiscus sp. Ostreopsis sp Prorocentrum sp. The study was conducted by taking a substrate attachment of benthic dinoflagellates from the seaweed, and then put them in a plastic screen of sea water. For the releasing of the benthic dinoflagellate the process agitation and filtration were used with filter of 250μm and 20μm. The samples observed by using microscope and Sedgwick Rafter Cell. The highest abundance was found at stations with high density (45.85 cells/gram). The research showed that the abundance and distribution of toxic dinoflagellate types of seaweed in coastal waters in Sungai Nipah was more influenced by local currents.Keywords : Dinoflagellata, Distribution, Sargassum sp, West Sumatera
