Abstract
Artisanal mining on the island of Bangka leaves a lot of damaged land surface covered by coarsesized tailings that are dominated by the quartz mineral and it causes soil to be extremely unfertile. The objective of the present research was to understand the impact of the clay and organic matter (OM) applications on the tailings for supporting the growth of an adaptive plant which is used in the present study is sorghum. The study was conducted on the artisanal mine closure land at Pangkalpinang, the clay material and cow dung were collected from locally near location. Land was prepared by constructing four treatments, i.e.: control, OM + NPK, clay + OM, and clay + OM + NPK. The amendment materials were applied by mixing the tailing on the 30 cm wide and depth on each planting strip with a distance of 70 cm. Sorghum seeds were planted with a spacing of 20 cm. Watering plants was done by utilizing the water pit at the beginning of germination and plant growth. The results showed that sorghum grown and survived only one month in the control treatment. Sorghum growth is very good on the treatment of clay + OM+ NPK, while the other two treatments result in stunted growth of sorghum. Keywords: artisanal mining, Bangka Island, clay
