Abstract

 AbstractThe class of gastropods is the largest class in Phylum Molluska. One of the habitat that is controlled by gastropod is mangrove forest. The structure of the gastropod community of phylum molluska is influenced by changes in environmental factors. This research was conducted in Lalang Village Sungai Apit Subdistrict Siak Regency, in March 2018. The purpose of this research is to know the structure of gastropod community which includes: type, density, diversity, uniformity, dominance, distribution pattern.To support the research data, also observed mangrove density and  water quality in Lalang Village in Sungai Apit Subdistrict Siak Regency. Sampling using line transect method was done on 3 stations. 6 gastropod species found in mangrove forest area with the value of gastropod density obtained at each research station is 3.57-4.84 ind / m2. the value of its diversity ranges from 1.02-1.11. while the value of uniformity obtained is 0.48-0.62 and the dominance value ranged from 0.14 to 0.17. Gastropod distribution pattern is uniform, type of mangrove that is found  is 6 species.Kata Kunci:Gastropoda, Comunity structure, Mangrove

ABSTRACT Gastropods and Bivalves are two important classes of molluscs living on the Terkul coastal area. Species of these class are often used by local people for livestock feed, handicraft materials and was consumed. This study aimed to determine the structure of community Gastropods and Bivalves in coastal areas of Terkul Rupat Bengkalis Regency. This research was conducted in February - May 2018. Sample collection of Gastropods and Bivalves taken from on 4 certain stations using quantitative and qualitative methods.From this research were found 17 species, consisting of 13 species of Gastropods and 4 species of Bivalves. The highest density of Gastropods is in Station III of 10.67 ind / m2 with characteristics ie near the Terkul port and mangrove grow rarely. The value of Diversity (H ') is high, ranging from 2.26 to 3.13, the uniformity value (E) is in the range of 0.43 to 0.59, the dominance value (C) ranges from 0.13 to 0.43. The distribution pattern of 12 species is clumped and 1 species is uniform. The highest bivalves density is at station III of 0.56 ind / m2 with characteristics ie near the Terkul port and mangrove grow rarely. The value of diversity (H ') is, ranging from 0 to 1.52, uniformity value (E) is ranging from 0 to 0.75, the dominance value (C) ranges from 0 to 0.37. The pattern of distribution of 3 species are uniform and 1 species clumped. Keywords: Community structure, Pulau Rupat, Gastropod, Bivalve.

Abstract

 ABSTRACT Cerithidea obtusa is one species of Mollusc from the family Potamididae which has economic value. This research was conducted in Maret 2018 in mangrove forest the village of Sungai Cingam Rupat Sub-District Bengkalis Regency. This research aimed to determine the populations structure of C. obtusa which cover density, distribution patterns and size distribution. This research used survey method and sampling location determinined by purposive sampling. Measurement of waters quality was done by in situ and ex situ which consists of physical and chemical parameters of the waters. Condition of substrate in the study area  was muddy, with sediment organic matter was high 10.69 % -13.95 %. The parameters of waters quality still support for the life of the gastropod. The average density was 5.3 ind/m2, the highest density was in upper zone and which the lowest at middle zone of the intertidal . The distribution patterns was uniform/evenly, while size of the gastropod found has a length 31,8-52,3 mm. Key words: density, size distribution, distribution patterns, C. obtusa.

Abstract

This research was conducted at North Bintan island waters. The sample of sediment and snail S. canarium hasbeen taken from four locations those were Busung, Lobam, Sebung, and Tanjung Bakau coastal waters. Analysisof metal concentrations both in sediment and snail conducted by using Atomic Absorption Spectrophotometer(AAS)Solar 969 AA. The result showed the highest concentration of Cadmium (Cd) and Cuprum (Cu) in sediment whichwere 0.51 ppm (Cd) and 13.22 ppm (Cu). While the highest concentration of these metals in snail S. Canarium wichwere 0.56 ppm (Cd) and 8.42 (Cu), indicating that the concentration in both sediment and snail still below thenormal threshold. It could be concluded that the Bintan Coast has not been polluted but lightly contaminated.

Abstract

The present study was carried out to investigate the biomass of cockle (Anadara granosa) from coastal waters ofSouth Indragiri District, Riau Province. The biomass was investigated by quadrad sampling method in the intertidalarea along the Concong beach, where fishing of cockles mainly occured. The first station was near by the Concongestuary, while the second station was about 3 miles away from the fisrt one. Samples were collected from threedifferent portions of the intertidal zone that of High Intertidal Mid-Intertidal, and Low Intertidal. The result showedthat the highest biomass was found at the lower partion of the intertidal zone. Soft tissue of A. granosa was about24.8% of total wet-weight and 7.2 % of dry-weight. While material organic was about 85 % of soft tissue dry-weight.Water qualities of the sampling station showed that the overall water qualities were still in normal condition.

Abstract

ABSTRACT The structure of the macrozoobenthos community in the mangrove forest area of Purnama Village, Dumai City can be used as a basis for knowing the environmental conditions of the waters in the mangrove forest of Purnama Village, Dumai City. This research was conducted in the mangrove forest area of Purnama Village, Dumai City in April 2018. The method used was the survey method, sampling was done by purposive sampling. The research location was divided into three stations and each station was divided into three transects, with each transect placed three 1 m2plots. The results showed an abundance of macrozoobenthos ranging from 7.56-10.00 Ind / m2, obtained 3 classes namely Gastropoda, Crustacea, and Bivalva consisting of 12 species namely Cassidula aurisfelis, Cerithidea obtuse, Littorina melanostoma, Nerita lineata, Nerita violacea, Littorina scabra , Chicoreus capucinus, Indothais gradate, Nassarius candens, Uca sp, Polymesoda expansa, Indothais malayensis and the most commonly found are Nerita lineata while the diversity index ranges from 2.79 to 2.98, the uniformity index ranges from 1.09 to 1.33, index dominance ranged from 0.15 to 1.16 and distribution patterns ranged from 2.53 to 3.32. The results of measurement of environmental parameters are still within the optimal limits for the life of marine biota and the dominant type of sediment is muddy. It was concluded that moderate species diversity, balanced uniformity and no dominant species were found while the distribution pattern was grouped. Keywords: Community Structure, Macrozoobenthos, Mangrove, Dumai City
