Abstract

This research was conducted on August 2008 with purpose has to know the characteristics of sediment at estuary of Indragiri river. The method used in thisresearch was survey method.The research found that there were 2 fractions of sediment I.E. mud and sand withthe type of sediment that were mud, sand, and muddy sand. Mean score for thesediment at the estuary of Indragiri River were between 1.72 to 7.14 Φ anddominated by medium class of silt and coarse silt. The sorting score were between0.58 to 2.10 Φ and dominated by a poorly sorted classification. Skewnes valueindicates the estuary area described that the coarse sediments particles and areas farfrom the mouth of the river showed a trend of fine sediment particles.Keyword: sediment, mud and sand

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

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 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

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

Abstract

The main purpose of this study was to reveal the depositional environmentand the movement of coastline. This study was conducted in January 2013 innorthern part of Rangsang Island, Meranti District. Sediment samples were takenfrom 11 station sand analyzed by using mechanical granular method. The methodof remote sensing linear regression was used to determine the movement ofcoastline. The result of study show that the surface bottom sediment ischaracterized by sand and mud fractions, and is dominated by bottom characterof sand. The study area was a transitional area where waves and currents werepredicted to change frequently through not too significant. The currents strengthtend to move with the fluctuations. The average change of the coastline during thepast 13 years (2000 to 2013) was 7,455 m/yr with the greatest changes occurredat station 7, i.e. Kedabu Rapat Village, with 8.54 m/yr. The speed movement ofcoastline was marked by the destruction of land cover in the north along the coastof the Rangsang Island as indicated by destruction of mangrove forests andvegetation coast, the sinking of jetty, roads and houses as well as the erosion.Kata kunci: movement of coastline, sediment coastal, Rangsang Island, abrat

Abstract

This research is aimed to determine the distribution of demersal fish schooling and the relation between demersal fish schooling and temperature, salinity and depth of water by using hydroacoustic method. The research was held in August 2014 at the Research Institute of Marine Fisheries Laboratory of Muara Baru, North Jakarta. This research used hydroacoustic method with acoustic descriptor techniques. The amount of fish schooling was obtained by digitization and integration, the values of integration would have generated the position and depth of the waters. Demersal fish schooling which found in waters of Tarakan were comprising of 19 schooling. The dominant fish schooling occured at temperature of 270 C to 280 C and tended to be appear at salinity of 35.5 ‰. Type of demersal fish schooling in Tarakan waters was mostly emerged in form of horizontal contained in the bottom of ocean.Keywords :Kalimantan, Tarakan, Demersal Fish, Fish Schooling , Hydroacoustic
