Abstract. Tin mining in Bangka Belitung has been exploited for hundred years. The province is the second largest tin producer in the world. Secondary data from studies which took place in all four regencies in Bangka Island were discussed to show the impact of mining activities and its reclamation studies. In order to add plant selection criteria for regevetate mined soil, the greenhouse and laboratory experiment was carried out with fourteen herbs and grass species in Tennessee. The mining activities increase the wealth of the community, but the other hand they change and decrease the environmental stability, and cause horizontal conflicts. Offshore mining reduced water quality, change sea bed caused the change of biodiversity. Onshore mining activity reduces biodiversity and causes floods and damages infrastructure. While the more economic species are demanded, planting local tree species is challenging. An evaluation with local tree species concluded that best adapted species based on anatomical and physiological measurements was not those that showed the best performance in the field. The greenhouse and laboratory findings indicate that some physiological characteristics i.e. plant height and cover, transpiration rate, and foliar pigments may be used to select plant adaptability to mined soil.

Unequal understanding among tin mining stake holders on trade regulation often triggered social conflict and therefore it was suggested to build political will especially among national, provincial, and regencial/municipal government levels. One important effort to bring out political will is presenting an independent and scientific study on comparision between socio-economic and environmental impact of tin mining. Purposive sampling was conducted to inconventional miners at reserved forest at Lubuk Kelik hamlet, pepper farmers at Silip village, and rubber farmers at Bencah village. Tin mining changed soil properties and microclimate, reduced vegetation composition and structure, arbuscular mycorrhizal fungi, phosphate solubilizing microorganism, ants, and Collembola population. Land conversion increased and contributed up to 95% income. The welfare improvement, however, was apparent as the recovery cost was neglected by inconventional tin miners, and only pepper land conversion showed benefit. Inconventional tin mining regulation needs improvement in order to increase land use efficiency and recovery cost. Understanding on ecological balance of more people and for more sustainable social welfare should be improved as well.
