Abstract

The research conducted from at 14 to 21 May 2009 in Estuary of AekTolang Pandan, North Sumatera Province with aimed to find out macrozoobenthos community structure which includes species, abundance, diversity, dominance anduniformity, to know the relationship of the content of organic matter abundancemacrozoobenthos. The method used was survey method. Primary data obtained fromthe measurements and sampling at locations in the research and analysis in thelaboratory.Macrozoobenthos encountered in the study area there ware 17 generas of 3classes, namely class Gastropoda, bivalva and polychaeta. Individuals from the classof individuals who gastopoda was most often found. The average valuemacrozoobenthos abundance ranged from 33.77 to 197.33 ind/m2, the average valueof diversity index ranges between 1.20-2.17; dominance index value ranges between0.29-0.48; index value uniformity between 0.82-0.94 and the index of similaritybetween 0.23-0.4. Sediment organic matter content of the abundancemakrozoobenthos showed that correlation were middle and higher and positive, itmean higher in organic matter would lead to higher in macrozoobenthos.1)Lecture of Fishery and Marine Faculty2)Student of Fishery and Marine FacultyKeywords: Community, Macrozoobenthos, Estuary of Aek Tolang Pandan

Abstract

This research was conducted in May 2009 in between District AekManis waters Sibolga North Sumatera in order to determine the correlationsediment organic material content and makrozoobenthos abundance.Determinantion of the research station was randomly composed of 4 station and 5sampling point where each point sampling distance of 200 meters wich werebased on the initial sampling paoint. Makrozoobenthos encountered and thestudy area there 26 genera of 3 classses, namely class gastropoda, bivalve.Polychaeta. Individuals from the class of individuals who gastropoda us mostoften found. On the whole it can be seen that the relation between sediment organicmaterial content and makrozoobenthos abudance show a positive correlation, thehighercontent of organic material wiil lead to the higher of the makrozoobenthosabundance.

Abstract

Activated carbon  monolith  (ACM)  was made  from  rubber  wood  for supercapacitor  applications  by using  two  activators,  namely  KOH  and  HNO3 . Carbonized sample were by N2 gas at a temperature of 600º C and were physically activated  by  CO2gas  at  800º C  for 2  hours.  KOH solution  of  1,  3  and  5M  was used  as  chemical  activation  solution.  ACM  electrodes  were tested  in  a two-electrode system,  which was stainless steel  as a  current  collector  and a 1M  H2SO4 solution  as  an  electrolyte  solution.  Electrochemical characterization  results by impedance  spectroscopy  methods  showed an increase  in the  capacitive  properties, followed by  a decrease in  cells  resistance. The  measurements  obtained the best capacitance  of  55.46  F/g.  XRD  patterns of  the samples showed  amorphous structure  and  SEM images  showed that  the  addition of  KOH  solution  resulted in the  pore  structure  of macroporous  and  mesoporous  combination.  In conclusion, this current result showed that the activator of KOH and HNO3have improved the performance of the ACM rubber wood electrode.

Abstract

The research was conducted in January-Februari 2015 in coastal waters of Jago-Jago, North Sumatera.The aims ofthis study were to determine the nutrient content of sediment in seagrass ecosystem and to determine the ratio of C:N:P in the sediments by different sediment characteristics and determine the relationship of nutrient with density and biomass of seagrass. The parameters measured were included physical and chemical parameters of marine waters. The density was computed using a quadratic transect, while seagrass biomass was calculated by measuring dry weight of shoot. The value ratio of C:N:P in the sediment was obtained through the determination of carbon (C) in total by the method of Walkley & Black, total of nitrogen by Kjehdahl method and phosphorus total with Double Acid method. The results showed the average carbon content was 1.32117 to 2.47813%, the average nitrogen content was 0.63114 to 1.5468% and the average phosphorus was from 0.00002 to 0.0004%. The density of seagrass in the village of Jago-Jago was between 29 to 56.3 shoots/m2 and biomass of seagrass was between 651.26 to 1261.34 g/m2. Station III had a ratio of C:N:P =12011:14062:1 and provided good leverage, this can be indicated also by the total biomass and density of seagrass at this station was the highest. The C-organic, Nitrogen and Phosphorus in the sediment with density and biomass of seagrass had a weak relationship, there are other factors that might affect the density and biomass of seagrass in which were not measured in this study.keyword : Density, Biomass, Seagrass Ecosystems, Ratio of C:N:P, Sediment, Jago-Jago Coast

Abstract

This research was conducted in March 2015 in the coastal waters of the village of Jago-Jago Central Tapanuli, North Sumatra. The aim of this research was to know the community structure of epiphytic diatom which include the type and abundance, diversity, uniformity and epiphytic diatom dominance contained in the leaves of Enhalus acoroides and to know the characteristics of the diatom habitat includes water quality parameters that affect the existence of epiphytic diatoms. Data were obtained by direct observation, measurement and sampling in the field followed by the identification of the type (species) of epiphytic diatom at the Marine Biological Laboratory, University of Riau. The results showed Total epiphytic diatoms found were 30 genera. The highest abundance of diatoms were Nitzschia and Skeletonoma that were recorded in station III. This genus has high adaptability pitch on the environment so that it can grow and develop properly. Diatom abundance of epiphytes on the leave base, middle and tip of the station I ranged from 31.093 to 71.035 ind/cm2, in the station II ranged from 59.093 to 92.855 ind/cm2 and at stations III ranged from 33.562 to 82.460 ind/cm2. The highest abundance of epiphytic diatoms was found in station II, ie 75.013 ind/cm2, while the lowest abundance was found in station I, 48.935 ind/cm2. The value of diversity index (H '), dominance index (D) and uniformity index (E), concluded that quality was diversity of species were, no species dominated and water quality was still in favorable condition to support the life of epiphytic diatoms.Key Words: Community Structure, Epiphytic Diatoms, Enhalus acoroides, TapanuliTengah

Abstract

The rapid growth of industrial sectors in various countries leads to an increase in greenhouse gas emissions (global warming) such as carbon dioxide (CO2) in the atmosphere. One important aspect of reducing carbon gas is the maintenance of forests and oceans to store carbon. One of the potential marine resources as blue carbon is seagrass beds. Development of Poncan Island into a marine tourism area estimated will endanger the existence of seagrass vegetation that makes marine ecosystems as blue carbon is reduced, one of them which is Cymodocea serrulata. The research was conducted in March-May 2017 in the seawater of Poncan Island, Sibolga, which aims to determine the content of biomass, average of C-organic, and find parts of seagrass as the largest blue carbon. Sampling using a quadratic transect method performed at 3 station. The results show that the largest biomass and blue carbon of all research sites located in the Below Ground section (roots and rhizomes) with value is 27,57 gbk/m2 and 6,13 gC/m2. The highest average C-organic content in all research sites located in the root of the seagrass with value is 24,17%.Keywords: Global Warming, Seagrass, Biomass, C-organic, Blue Carbon, Poncan Island

Abstract

The species existence of dinoflagellates , i.e. Gambierdiscus sp., Prorocentrum sp. and Ostreopsis sp in the waters can cause disease, poisoning and blooming. This will cause disruption of aquatic ecosystems that cover the water surface and light penetration into the body of water will be hampered. Research to determine the abundance of toxic dinoflagellate epibenthic on seaweed Padina sp. in Sungai Nipah waters was conducted in August 2015. Sampling of epibenthic dinoflagellates attached to Padina sp was performed in three stations and each station consists of three sampling points.The results showed that the highest abundance epibentic toxic of dinoflagellates in the coastal waters of Sungai Nipah found at station 3 (803.28 cells / g). The highest abundance from all stations was a genus of Prorocentrum sp., with the total number of 947.74 cells/g, genus Gambierdiscus sp. had the smallest abundance at each respective station with a total of 41 cells/g while Ostreopsis sp has a evenly abundance in almost every station with a total abundance 562.93 cells/g.Keywords: Abundance, Epibenthic, Dinoflagellates, Toxic, Padina sp., Sungai Nipah Waters
