Abstract—The Ni-contaminated soil was obtained from post-mining sites in Sorowako, South Sulawesi in which Soybean (Glycine max) and Melastoma were grown together in a pot experiment. The design of treatment was factorial design of two factors i.e. urea dose (0, 100, 200 and 300 kg/ha) and kind of compost (without compost, Chromolaena compost, Glyricidia compost and Husk compost 20 ton/ha). Biomass production and accumulation of nickel in the shoots (parts of the plant above ground) and roots (underground plant parts) were analyzed to determine the ability of plants to accumulate nickel. The values of Bioconcentration Factor (BCF) of the plant was calculated to analyze bioremediation of the plants. The results showed that urea and compost applications, especially Chromolaena and Glyricidia compost increased dry weight of soybean and Melastoma. In addition, application of urea and all types of compost resulted in decreased nickel accumulation in both soybean and Melastoma. Increased urea dose up to 100 kg/ha without compost caused BCF value increased to 0.24 in soybean (moderate accumulator category).
