Abstract

This study wasconducted inFebruary - April2012 in Buatan Lake Waters Pekanbaru City.Theaimed of this study was to determine of the pollution level of Buatan Lake waters base onofphysical, chemicalandbiological parameters. The method used was surveymethod.Samples were takenat4 (four) stationsand5 (five) pointseach stationwith samplingintervaloftimeoncea month. The result of this study showed that physical and chemicalparametersweretemperature 28.7 to 30.8°C, depth 1.4 to 3m, the brightness 46.3 to 70.9cm, pH5.7 to 6,dissolved oxygen 1.11 to 1.55mg/l, BOD54 to 5mg/l, COD 26 to 32mg/l, TSS39 to 48mg/l,total organic matter in the sedimen 22 to 33%, and most of the stasions dominatedbymudsubstrat.Macrozoobenthosfoundas many as3(three) species (Tubifexsp, ChironomusspandHesperocorixasp). The average of macrozoobenthosabundance was791 ind/m2. Base onstatistical analysis (Anova)found that no significant differences abundance between stasionsFcalc.≤ Ftab.was 0.90<4.76), as well as between months. It could be conclude that BuatanLake waters had been heavily polluted, only a few high tolerance organism could be survive.

Abstract

This research was conducted on August 2013 at Pesumpahan Coast and Pisang Coast waters in West Sumatera with the purpose to examine the abudance of dinoflagellata epibentik from genera Ostreopsis, Prorocentrum and Gambierdiscus that sticks to seagrass Halophyla and macroalgae Padina and also to know the effect of the degradation of the coral reefs toward the increase of dinoflagellata epibentik. The method used was survey method. The analysis and identification were done in laboratory of Sciences Environmental Post Graduate Program Universitas Riau. the abudance of dinoflagellata epibentik from genera Ostreopsis, Prorocentrum and Gambierdiscus in Pesumpahan Coast was not different with the one in Pisang Coast. The degradation of coral reefs did not effect the increase of dinoflagellata epibentik but more to the presence of seagrass and makroalgae as the place of dinoflagellata epibentik to stick on

Abstract

This research was conducted in June 2013 at Riau River Estuary inTanjungpinang City Riau Islands Province. This research aimed to find out themacrozoobenthos community structure and its relationship to seagrass vegetation.The method on the research was survey method. The existence of macrozoobenthosin this area showed the dynamic symbiosis among seagrass and marine organisms.The results also showed seagrass ecosystem had the high potential to be managed andused by communities and also increasing the fisheries productivity on coastal area.Species composition of macrozoobenthos in the area consisted of 8 species, i.e.Strombus sp, Cerithidea quadrata, Pina bicolor, Anadara sp, Anadara inflata,Atactodea striata, Asteroidea sp and Diadema sitosum. Two species of seagrassvegetation were found in this area, those were Enhalus acoroides, and Halophilaovalis. T-test analysis showed that the average of macrozoobenthos abundance oneach station differed unsignificantly (p>0,05). The regression analysis showed thatrelationship among seagrass vegetation diversity and macrozoobenthos abundancewas at r=0,35.Keywords: Riau River, Macrozoobenthos, Seagrass, Symbiont
