ABSTRACT
Silandak Estuary is one of the subsystem drainage areas in West Semarang that flow into the bay of Semarang. The estuary is a place of accumulation of domestic sewage and factories. Coastal reclamation at the downstream estuary Silandak causing sedimentation that will affect the existence of macrozoobenthos. The purpose of this research was to know the sediment texture, organic matter content and abundance of macrozoobenthos. The material used in this research is the sediment samples and samples of macrozoobenthos at any station located at the estuary to the coast of Maron. The research used random sampling with four stations. At each station there are three sampling points, samples of sediment and makrozoobentos taken at any point which then composite sample at each station. The sampling was done with time interval of two weeks with three repetitions. The results of the sediment texture at the station I has the texture of clay while the station II, III and IV have a texture of sandy clay loam. The results of the organic material content at stations I, II, III and IV is amounted 19,33%, 15,20%, 13,40% and 10,67% and while abundance of makrozoobentos at station I are 652 ind/m3, station II 696 ind/m3, station III 783 ind/m3(higher) and station IV 261 ind/m3 with a diversity index categories clean water zone and not found the dominant species.
