The study was conducted in August 2013 in the coastal waters of Pandan Beach North Sumatra Province. The method used in this study was a survey method. This study aims to determine the environmental condition of water, the type and abundance of macrozoobenthos, and its sediment organic matter relationships. makrozoobenthos abudance Sampling was designed by purposive sampling to collet macrozoobenthos by using 15x15 cm2 Ekman grab. The results showed the macrozoobenthos species found in the coastal waters of Pandan Beach composed of Anadara granosa, Cerithidea cingulata, Polymesoda expansa, Terebralia palustris, Turbo petholatus, Volema myristica, Telescopium telescopium, Nerita lineata, Hippopus porcellanus, Terebra maculata, and Terebralia sulcata. The macrozoobenthos abundance in the studied area ranged from 192,6-1,066.7 individuals/m2. The analysis of the sediment organic matter showed strong position relationships with macrozoobenthos abudance.Keywords: Organic,Sediment, Macrozoobenthos, Abundance, North Sumatera

Abstract             The gastropods play an important role as bioindicators of environmental quality due to its living habits is relatively sedentary in one area for a long period and pass the impact of environmental changing. This research aims to recognise types, abundance, distribution of gastropods and the relationship organic content of sediment to the gastropods abundance. This research was held atn November 2017 in mangrove ecosystem Sungai Cingam Village, Rupat Subdistrict, Bengkalis Regency. The method used was survey method, meanwhile the determination of research points were measured by purposive sampling method. The research area was devided into 3 (three) stations where each station consists of 3 (three) transects. Each transect has 3 (three) plots measuring 3m x 3m. The results of research on mangrove ecosystem of Cingam River Village found 18 species of gastropods. Abundance of gastropods ranged from 13.44 to 16.19 individuals / m² with the highest abundance found in Station II with good mangrove forest condition Grouping is distribution formula of gastropods in mangrove ecosystem at Cingam Village. Organic content of sediment is around 6.96% to 8.98%.The highest organic content in Station II and the lowest in station III. The result of simple regression test obtained the equation y = 5.2158 + 1.2555x with correlation value (r) = 0.812 indicates strong connection between organic content of sediment and abundance of gastropods. Keywords : Abundance, Gastropods, Mangrove Ecosystem, Bengkalis

Abstract

The purpose of this research was to know the condition of nesting beaches favored by green turtles (Chelonia mydas) and the effect of incubation temperature (heating source from incandescent) towards the incubation and hatching rate success. This research was conducted in October to December 2016 at the Turtle Breeding Facility at Jemur Island. This research used survey and experiment method. The research showed that the safe nesting ground with some vegetation on location I and the least predator at the location II, the wide beach area, and sloping beach with fine sand which making it easier for green turtles in digging the nest. These conditions were the reasons why green turtles choose Jemur Island as their nesting ground. Incubation temperatures effects the hatching rate success and hatching time of sea turtle’s eggs. The treatment that has the highest hatching rate is a 25 Watt light with average temperatures of 29.7oC which is 83.33%. Treatment using a 25 Watt light is the best treatment, with a highest numbers of hatching rate and has the fastest hatching time. Keywords: Hatching Egg turtle, Chelonia mydas, Jemur Island

Abstract

The study to observe the species composition and abundance on mudskipper fish was conducted in July 2013 in Dumai coastal waters of Riau Province, Indonesia. They study was carried out in providing the lack information on the biological aspects of the mudskipper from Indonesian seas in general, and of the riau’s coasts in particular. They study used a survey method by selecting 3 different stations as the sampling sites. Fish sampels were collected during the low tide. The quadrant were used in the field in facilitating the survey in fish abudance, whilst the identification was commenced in the Laboratory of Marine Biology of University of Riau. The resuld showed that a number of three species of the mudskipper were sucessfully recorded, i.e. Periopthalmodon schlosseri, Periopthalmus variabilis (Eggert) and Baleopthalmus boddarti (Pall). In terms of abudance, the highest, 0,1733 individuals/m2 was recorded in station I and the lowest 0,0867 individuals/m2, was found in stations III. Based on the diversity index (H’), it was reported that the Dumai coast had moderate diversity of the mudskipper. None of the fish was dominating the population since the dominance index (C) was very close to null from each station. It can be concluded that the habitats of mudskipper in Dumai coasts were in the state of unstable due to its E value in which also close to one.   Keywords : Mudskipper, species composition, abudance, Riau

Abstract

This research was conducted on June 2015 in mangrove ecosystem of Liong River Estuary, Bantan District, Bengkalis Regency. The purpose of this research is to know abundance, distribution pattern and sex ratio of Lokan Bivalve (Polymesoda expansa). The method used was survey by observing, measuring and taking sample directly on research site. The research site was determined by purposive sampling which consisting of 3 stations, specified by mangrove densities. The result showed that average abundance were 0.44-1.66 ind/m2. The highest abundance was at Station 1 and the lowest was Station 3. The distribution pattern based on Morisita Index was aggregated. The sex ratio showed that difference among male and female at station 1 and 2, where the percentage of female was more dominating. While, sex ratio was balance on Station 3.Key words : Abundance, Sex Ratio, Distribution Pattern, Polymesoda expansa

Abstract

ABSTRACTSeaweed community is ecologically refuge, foraging and orphanage for marine life, including macro epizoobenthos. The existence of a food source will affect the density of macro epizoobenthos in the aquatic ecosystem and important its influence on the structure of the food chain in the community of seaweed. This study was conducted in March 2018-April 2018 in Nirwana Beach of Padang City West Sumatra. The aims of research to find out : the density of each type of seaweed, the abundance of a macro epizoobenthos that lives on seaweed community and the relationship between the density of seaweed with a abundance of macro epizoobenthos. Sampling and measurement of water quality was done by using quadratic transect at 3 stations. The results of the study showed that the highest seaweed density has a value 451.4 tegakan/m2 and thehighest macro epizoobenthos abundance has a value 244 ind/m2in the area of seaweed that minimal activity and the lowestseaweedabundance has a value 169 tegakan/m2 and the lowestmacro epizoobenthos abundance has a value 27 ind/m2 in the area of seaweed around the population and settlement activities. The relationship of the density of seaweeds with the macro epizoobenthosdensity very strong i.e. y = 6.371 –0.553x; R² = 0.678; r = 0.82.Keywords: Seaweed Density, Macro Epizobenthos, Abundance, Nirwana Beach

Abstract

AbstractMacrozoobenthos is a living organism that is relatively sedentary (sessile) and has varying adaptability to environmental conditions. In addition, macrozobenthos is also widely used as an indicator of pollution. This research was conducted in the waters of Pasumpahan Island, Bungus Subdistrict, Padang City, West Sumatera Province in April 2018, aiming to know macrozoobenthos community structure which includes: type, abundance, index of species diversity, uniformity index, dominance index and distribution pattern. Sampling using line transect method is done on 3 stations. The results of the study found 4 classes of macrozoobenthos with 9 species, where the value of macrozoobenthos abundance obtained ranged from 3.22 to 3.78 ind/m2. The index value of diversity of species ranged from 0.40 to 0.57 is relatively low, while the value of uniformity index ranged from 0.12 to 0.19 is not balanced, the value of the dominance index ranged from 0.12 to 0.18 ie no species which dominates and the value of the distribution pattern ranges from 3.21 to 5.09 with the pattern of distribution in groups.Keywords: Makrozoobenthos, Intertidal Zone, Pasumpahan Island, Community Structure
