Tin mining activities in hundred years in Bangka Island formed thousands of pond water, referred to askolong. The water from kolong has been utilized by arounds people as a source of clean water and tobe the main water resources by local water company (PDAM). Unconventional mining around kolongcaused contamination of water by heavy metals from tailing, therefore the study of heavy metals inkolong is very important to do. Data collection was done through the approach of physical andchemical parameters of water and sediment Kolong Retention Kacang Pedang. Water and sedimentphysical data collection for getting parameter of colour, flavor and smell. Chemical analysis of waterand sediment cover of Dissolved Oxigen (DO), Chemical Oxigen Demand (COD), Total DissolvedSolid (TDS) and Total Suspended Solid (TSS), pH, and the content of heavy metals usingspectrophotometer and XRF. As a result, the heavy metal composition of Fe, Cu, Pb and Cd inwater exceed the normal threshold. Element Fe in sediment has the largest number over all sample,followed by Zn, Cr, Cu, Pb and As. The metals of Cu and Zn is absent from sediment around outletarea of Kolong Retention Kacang Pedang

Land Clearing for tin ore mining on Bangka Island for hundreds of years produces mine ponds calledkolong. Water resources at the old age kolong have been utilized by the community as a source ofdomestic water, including the source of water by Regional Drinking Water Company (PDAM). Illegal tinore mining since 2000 until now by the community (unconventional mining) has caused pollution ofPDAM water resources by mining waste of tailings. Primary and secondary data collection has beendone on Kolong PDAM Tirta Bangka, PDAM Tirta Pinang and PDAM Sejiran Setason. Physical datacollection of water and sediments to obtain parameters of temperature, smell, soluble and suspendedsolids and turbidity. Chemical analysis of water and sediments including pH, heavy metal of Fe, Al, Pb,and Cu using AAS and XRF. Feasibility evaluation of the water using Permenkes RI Number907/Menkes/SK/VII/2002. Heavy metals were founded on all the water of kolong are Fe, Al, Cu andPb. Heavy metal in sediment are Fe, Cu, Pb, Sn and As. Kolong Merawang has a large distribution ofFe, Al, Cu and Pb in water and sediment. Al metal exceeds the threshold in Kolong Merawang andPedindang (1.01 mg/L and 0.35 mg/L). The Fe composition at all kolong sediment is very large innumber. The distribution of dissolved Pb metal in water exceeds the threshold at all kolong, especiallyon sediment of Kolong Merawang and Pedindang. Water resources at all kolong have met in physicalfeasibility but exclude their chemistry

Rare earth element REE is very potential future prospect mineral resources in Bangka Island, hence awell developed REE must have a high economic value in the future. As one of the biggest region thatproducing tin ore mining (cassiterite) for hundreds of years, REE potential not yet explored andexploited well until now days in Bangka Island, and was left abundant in ex-mining area. They carriedout from the tin ore mining and become mine waste or tailing and then through the stream flows to besuspension or bed load sediment. The aim of this study is to identify the present rare earth Ce and Ybased on shallow surface sediment samples and their spatial distribution from a number of mineponds called kolong. Primary data collection of shallow surface sediments has been collected onKolong Argotirto and Menjelang West Bangka District, Kolong PLN and Merawang in Bangka District,Kolong Rentensi Kacang Pedang and Pedindang in Pangkalpinang City. Geochemical sedimentsanalysis just for identification the presence of rare earth Ce and Y. Rare earth element of cerium(Ce) just presence in a few sample sediment, but for yittrium (Y) almost presence at all shallowsurface sediment 0,9 - 31,6 ppm. The spatial distribution of rare earth Ce and Y show heterogeneity inlaterally.

Studi Unsur Radioaktif Thorium (Th) dan Uranium (U) di Pulau Bangka Irvani Irvani; Janiar Pitulima

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.

Magnetic separator testing uses two variables, namely the speed of the roller on the conveyor belt andthe feed speed. Due to the minimum number of variations that can be used in magnetic separatortesting, roller speed testing is used at 0.6 m / s and 0.7 m / s. the variation of figures at the feedingspeed of 0.21 kg / s and 0.35 kg / s so that 8 samples obtained from the processing of a magneticseparator with 4 magnetic samples and 4 non-magnetic samples. The feed samples used wereprepared by drying and sifting into 3 size fractions to be used in the grain counting analysis process sothat the percentage of minerals contained in the sample were found: 15.82% Cassiterite, 63.95%Ilmenite, 6.09% Monazite, 0.48% Pyrite / Marcasite, 1.61% Zircon, 1.44% Topaz, 0.65% Tourmalineand 9.96% Quartz. The effect of roller speed on the increase tin ore content is still common, this isbecause there are not many experiments carried out so that taking the trend of the influence of theroller speed is too fast. The effect of feed speed, the greater the feed speed on the magneticseparator, the smaller the tin ore content obtained.
