Abstract

Makrobenthos that live in the mangrove forest can be used to predict the role or contribution of mangrove ecosystems as a source of natural food for the environment. The aims of research to determine the structure, composition, abundance, diversity makrobenthos of the mangrove ecosystem. The study was conducted by comparing the community structure makrobenthos in pond ecosystem with mangrove vegetation constituent . The location of this study include three areas , Mangunharjo ( Semarang), Surodadi ( Demak ) and  Pasarbangi. The result can shows makrobentos species composition is dominated by gastropods ( 18 species) , Bivalvia ( 13 species ) , Polychaeta ( 3 types ) , and crustaceans ( 2 types ) . Cerithium and Littorina scabra is a type that has a high density of the mangrove ecosystem . There are differences in the abundance and diversity of plankton and makrobenthos at three study sites. In general Pasarbangi Coast has the highest abundance and diversity . Macrozoobenthos community structure in mangrove ecosystems that exist in the three study sites in a stable state , species diversity and distribution of the number of individuals of each type of uniform . Pasarbangi area with mangrove vegetation polyculture farms , have high primary productivity . This shows the level of primer productivity at the site is also high.   Keywords: community structure, macrobenthos, pond ecosystem

Abstract

Disturbance of water environment due to organic enrichment caused by farming activities may result in the reduction of water quality and sediments. This study was conducted to determine the condition of the water and sediments in the area of aquaculture in ponds system compared to the adjacent coastal area of industrial activities. Water qualities observed were the temperature, DO, salinity, conductivity, turbidity and pH. Sediment characteristics measured were sediment grain size and organic matter content contained in the sediments. From the research, the temperature values obtained ranged 28.7-32.9°C, DO 3.63 to 6.4 mg/l, pH 4.31 to 6.27, salinity 4.6 to 33 ‰, conductivity 8.5- 50.2 ms/cm, turbidity 73-535 NTU. The substrate grain analysis showed at the fish farm area in pond systems was dominated by silt 71.70% and clay 16.71%. In the coastal area adjacent to the industrial activities, 93.38% substrate was dominated by sand. Analysis of organic matter content in the pond systems exhibited the highest ranged between 0.72% -1.16% for nitrogen and 3.20%-10.35% for carbon. The differences in the composition of the substrate and the organic material can be caused by hydrographic conditions, especially strong/weak water currents, the accumulation of litter originating from the decomposition of leaves of mangrove, enrichment of nutrients during the decomposition of litter and aquaculture activities and industries.
