As one of the island that producing tin ore mineral (cassiterite), Bangka Island has probably a bigpotential of tin associated mineral that contains radioactive elements like Thorium (Th) and Uranium(U). Th and U can be one of potential future prospect elements expecially for nuclear energy. Th andU elements bearing minerals in Bangka Island not yet exploited. They take out from the tin ore miningand becoming tailing, and then through the surface water flows or shallow sea water as sediment. Thestudy goal is to getting the number of radioactive Th and U elements using surface sediment sampleand then interpretation some part of their spatial distribution form. The Surface sediment data hasbeen collected on 2 sites Kolong in Muntok District West Bangka Regency, 3 sites in MerawangDistrict Bangka Regency, 9 sites in Pangkalpinang City, 2 sites in Central Bangka Regency and 2sites in South Bangka Regency. Chemistry analysis of sediments for identification the presence of Thand U elements. Radioactive element of Uranium (U) almost presence at all shallow surfacesediment 4.842 - 229.2 ppm except nul in 1 sample. Thorium (Th) just presence in a part of sedimentsample. One site as especially case study Kacang Pedang Retention Ponds, shows Th and Uradioactive elements has the heterogenity spatial pattern.

Abundance And Distribution

Foraminifera are generally live in sea water with various sizes. These organisms consist of planktonic and benthic foraminifera. Geological activity on plutonic and volcanic with vomiting magma is transpiring on, and then affects sedimentation and foraminiferal abundance of Ambon Bay. The study was determined to study the abundance and distribution of foraminifera based on the sediment characteristic of Ambon Bay. Sample collected in 2007 of Ambon Bay showed that only 29 samples of 50 samples containing foraminifera. The collected sediments have 86 species of foraminifera, consisting 61 species of benthic foraminifera and 25 species of planktonic foraminifera. The dominant benthic foraminifera in the surface sediment of Ambon bay were Amphistegina lessonii, Ammoniabeccarii,Elphidium craticulatum,Operculina ammonoides and Quinqueloculina parkery. The planktonic foraminifera that were frequently collected from the bay were Globorotalia tumida, Globoquadrina pseudofoliata, Globigerinoides pseudofoliata, Globigerinoides cyclostomus dan Pulleniatina finalis. Generally, the species dwelled as abundant on substrate sand, whereas the areas within substrate mud have no foraminifera lie on them. Keywords: Foraminifera, Abundance, Sediment, Ambon Bay
