Abstract

This research was conducted in March 2016 in Pasumpahan Island at district Bungus, Padang city, province of west Sumatera. The purpose of this research was to know the condition of the coral reefs, such as: the percentage of living coral, variety, Uniformity, and domination based on life form of the coral. The method in this research was survey method by using Line Intercept Transect (LIT). It was consisted of three stations where each station was divided into two sub-depth (4 and 8 meters depth). The results show that the form of coral growth consisted of Acropora Branching (ACB), Acropora Encrusting (ACE), Acropora Submassive (ACS), Acropora Digitate (ACD), Acropora Tabulate (ACT), Coral Branching (CB), Coral Massive (CM), Coral Encrusting (CME), Coral Submassive (CS), Coral Foliose (CF), Coral Heliopora (CHL) dan Coral Mushroom (CMR). The condition of coral reefs in Psumpahan Island was good in the dept of 4 meter (60.70%) and in the dept of 8 meter (56.85%). Life form diversiy was moderate (H’ 2.99),while domination was low dominace (C 0.15), as well uniformity (E 0:37).Keywords : Condition, Coral reefs, Pasumpahan Island.

Abstract

This study has been done in Bantan Beach of Bengkalis Regency in Riauin December 2014. This research aims to understand the analyze oil contentdistribution, observing the environmental conditions. The research used surveymethod. The samples were taken from three stations, The water qualityparameters measured were covering temperature, transparency, pH, salinity, andcurrent speed. The result showed the highest oil concentration highest tide was atthe station II,i.e: 0.189 ppm and lowest at stationIII,i.e:0.130 ppm. The highest oilcontent at low tide was at station III,i.e: 0.111ppm and the lowest was at station I,i.e 0.058 ppm. The water quality parameter at the highest tide was temperature31oC–32 oC; transparancy 46-48 cm; pH: 8; salinity: 30.3-31 ppt, currentspeed:0.17-0.24 and lowest tide were temperature of 30.3oC–31 oC; transparancy43-45 cm; pH: 8; salinity: 29.67-30 ppt, current speed:0.16-0.22 m/sec. Theresults obtained showed that the average oil content the tide was higher than theaverage oil content at low tide. The concentration of oil content in Bantan Beachshowed in the range support the aquatic organisms life.Keywords : The oil content, highest tide and lowest tide, Bantan Beach

Abstract

This research was conducted in February 2016 in the bungus coastal, Teluk Kabung. This aims of this research was to know the variant of type and abundance of epiphelic diatoms which saw from low tide activites (long soaked) and characteristic of the research location includes waters quality parameters and inform about waters domain ecology includes diversity, uniformity and dominance in around the bungus coastal, Teluk Kabung, West Sumatera. Data were obtained by direct observation, measurement and sampling in the field followed by identification of the type (species) of epiphelic diatoms at Marine Biological Laboratory, University of Riau. The results showed total epiphelic diatoms found were 12 species . That were Rhizosolenia sp, Guinardia sp, Triceratium sp, Melosira sp, Cerataulina sp, Hemiaulus sp, Dactyliosolen sp, Pseudo-nitzschia sp, Rhabdonema sp, Navicula sp, Cylindrotheca sp, dan Pleurosigma sp. The average abundance of diatoms based on zone each station highest was lower zone and lowest was upper zone. The value of diversity index (H’), uniformity index (E), and dominance index (D) show that the condition of research location has value which was in high diversity, organism uniformity wasn’t balance and no species dominated. Based on ANOVA test, concluded that abundance of epiphelic between each stasiun weren’t significant and abundance between each zone were significant.Keywords: Type and Abundance, Epiphelic Diatoms, Intertidal Zone, Teluk Kabung Bungus

This Study aims to obtain the optimalconcentration of extract Keben (Barringtonia asiatica) for the process ofimotilization of Silver Pompanoo Fish. The test animal used is Silver Pompanoo(Trachinotus blochii) with size 150-200 gr. On the basis of preliminary results, theexperiment were carried out with 4 treatment concentrations of 13,79 mg/l, 19,00mg/l, 26,00 mg/l, 35,50 mg/l, and 0 mg/l as controls. Anova test showed thatconcentration had significant effect (P<0,05) on induction time, recoveredconscious and survival rate of Silver Pompanoo. The results showed thatconcentration 13,79 mg/l was the optimal concentration for Silver Pompanooimotilization process with induction time ranged from 15-17 minutes andconscious recovering time around 4-5 minutes and long fainting for 4,5 hours andresulted in rate of life equal to 86,6%.Kata Kunci : Barringtonia asiatica, Trachinotus blochii, imotilization.BAB I.

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 research was conducted in December 2016 at the Selat Baru Beach of Bengkalis District, Riau Province. The aim of the research is to find out and to analyze, the characteristics of sediment and the distribution of crab Scopimera globosa, as the influence of sediment grain size on the abundance of crabs. This method used was survey method and the sampling location determined by purposive sampling. The location were divided into three stations and at each station there were three sub-stations spread in the intertidal zone and split three sub-zones to : upper, middle and lower. The type of sediment on this beach consisted of sand fraction and dominated by fine sand, with the distribution of the fraction from Well sorted, Moderately well sorted, Poorly sorted and Very poorly sorted. The distribution of crabs Scopimera globosa was a clumped pattern on each station with the highest abundance value in second station located and the middle sub-zone (the most productive zone for growth of the crab Scopimera globosa) and the sediment mean size to contributes 1.2% in control to distribution of the crab Scopimera globosa.Key words : Sediment Characteristics, Distribution Scopimera globosa, sand fraction, Sub-Zone Middle, Contribution of 1.2%.

Abstract

Density and distribution population of sea urchin Diadema setosum was conducted in May 2014 at Setan Island. The research aimed to know about its density and distribution pattern. The study used survey method by applying transect and plot. The location of research was covering 3 stations. The stations were chosen base on existence of sea urchin D. setosum on coral reef (reef flat). Transect drawn from 5 m up to 15 m depth during low tide. There were there three plots with a size of 3x3 m² along the transect .The results showed that the sea urchin numbers was 332 individuals, where the density range value was 1,367 individuals/m2. The highest density was recorded at station I and the lowest density was found at station III. Morisita indeks dispersion showed that the location had a uniform distribution (Id<1), except for station III had a clumped distribution (Id>1). The highest size frequency of sea urchin D. setosum was ≤2 cm dan the lowest was 4,1-6 cm.Keywords: Setan Island,Density, Distribution,Diadema setosum
