ABSTRACT
Sediments and organic material have an essential role for grain size Bivalvia's life in the coastal environment. Sediment is a place for attaching and crawling or benthic organisms, while organic material is a source of nutrients. Sediment characteristics will be affected morphology, functional, behaviour and nutrients. This research was conducted in July 2019 at Prawean Bandengan Beach, Jepara. The purpose of this research was to determine the abundance and diversity of Bivalvia, texture of sediments and organic material and the relationship of Bivalvia abundance for texture of sediment and organic material. The method was used the descriptive with a purposive random sampling technique. Data analysis was conducted using IBM SPSS Statistics 16. The results obtained were three species of Bivalves in Prawean Bandengan Beach namely Anadara antiquata, Gafrarium divaricatum and Gafrarium tumidum with an abundance of individuals of 45 ind/100 m2; 29 ind/100 m2 and 64 ind/100 m2. Diversity values at stations I, II, IV and V ranged from 0.76 to 1.01 in the low to moderate categories. Sediment texture at stations I (d’season premiere), II (Julie hotel), III (ponds), IV (seagrass fields) and V (residents) was clay sand while station IIIwas sandy clay loam. The content of organic sediment was around 3.696 – 7.846% with a low category. Environmental disturbances as impact of human activities in utilising natural resources can affect the stability of a community, as predicted by the results of this study, especially seen from the community of malacofauna (Bivalvia),diversity is low, high uniformity and no species that dominate in the sandy substrate that contains low organic matter. The relationship of sediment texture with Bivalvia sand silt and clay fractions were low correlated, while the relationship of organic material content with Bivalvia was strongly correlated.
