Abstract

Research was conducted in January - February 2010 West Coast Aquatic region Pekalongan Village, District Tambak, Bawean Island, Gresik, East Java. The purpose of this study is to determine the composition and density of macrozoobenthos, distribution pattern and the relationship between the density of macrozoobenthos with ecological factors in coastal waters Bawean Pekalongan village. The method used in this research is survey method. These research activities include the collection and compilation of data, data analysis and interpretation, then the data were analyzed by descriptive about events that occurred during the research. Location of the study were divided into 3 stations where each station consists of 4 transects / quadrant and distance between the quadrants 20 m. Macrozoobenthos sampling was done by a depth of ± 20 cm. From the research that has been done, it was found that had been discovered makrozoobenthos consists of 4 classes, 7 orders, 11 families, 12 genera and 14 species. Macrozoobenthos densities are found in the waters of the west coast village of Pekalongan of each station from the highest to the lowest, ie Station II with a total 515 sq Ind/4m argillaceous sand substrate conditions, the average temperature of 31.5 ° C, salinity 27, 5 ppt, pH 8; soil organic matter 4.21%; TOM 6178.87 ppm. The second density is the third station with a total 385 sq Ind/4m with sand substrate conditions, the average temperature of 28.8 ° C, salinity 30.8 ppt, pH 8; soil organic matter 6.48%; TOM 6389.01 ppm. Final density of the station I with a total 239 ind/4m² argillaceous sand substrate conditions, the average temperature of 34 ºC, salinity 26 ppt, pH 8; soil organic matter 5.44%; TOM 5603.75 ppm. The density of each organism to all stations station I got the highest density is Clypeomorus coralium species of 210 ind / m² (87.86%) and lowest density is Clibanarius vittatus 1 ind / m² (0.41%). Station II is the highest density of species Clypeomorus coralium of 412 ind / m² (80%) and lowest density is the major Callichirus 1 ind / m² (0.19%). Station III kep [adatan Clypeomorus species coralium highest is 294 ind / m² (76.36%) and lowest density is Loligo peali, Synalpheus laevimanus and major Callichirus 1 ind / m² (0.25%). The pattern of distribution of macrozoobenthos in coastal waters west of the village of 11 species of Pekalongan is uniform and there are 3 species groups. Which includes a uniform pattern, namely: Planaxis savignyi, Nassarius echinatus, Nerita plicata, granosa Anadara, Chione granulata, Loligo peali, Synalpheus laevimanus, Callichirus major, Clibanarius vittatus, Callinectes sapidus, and Arenaius cribrarius. While that includes the pattern groups: Nassarius luridus, Clypeomorus coralium and Nerita antiquata. Macrozoobenthos community structure is as follows: Diversity (H ') 2,065 – 3,106, diversity ranges from 0,869 – 1,145. This means that diversity is and the kind penybaran evenly distributed and clustered. Can be concluded that the highest density of macrozoobenthos there at the station II and the lowest densities found at station I. Distribution pattern is uniform and in groups. Ecological factors are most influential to the life of macrozoobenthos are organic materials, TOM and soil texture. In need of counseling to the surrounding community in order not to dispose of waste at random (beach) because it will affect the ecosystem of organisms (macrozoobenthos) present in the waters.
