<p align="justify">Nickel mining industry is one of the largest industry in Indonesia. One of the most <br /> <br /> generated solid waste of the nickel mining industry is nickel slag. Based on Government Regulation Number. 101 in 2014, nickel slag is classified as <br /> <br /> hazardous waste (B3). Along with the increase of development in the mining <br /> <br /> sector, the increase will occur also in the amount of waste produced, including the <br /> <br /> hazardous waste (B3) which can harm the environment and human health. <br /> <br /> Therefore, it is necessary efforts to use back the nickel slag into a be a safe <br /> <br /> product to minimize environmental pollution.. Nickel slag utilization was <br /> <br /> conducted by solidification into kanstin and paving block products. Nickel slag <br /> <br /> was used as fine aggregate material to subtitude the sand. Compressive strength test results showed that the compressive strength of nickel slag waste <br /> <br /> solidification products can be used as a paving block for class C and D. However, <br /> <br /> no results of compressive strength which comply the requirements of the <br /> <br /> compressive strength for kanstin products. The heavy metals test results showed <br /> <br /> there are are 4 types of metal as a potential major polluters, Ni (310.5 mg / kg), Cr <br /> <br /> (25.4 mg / kg), Co (4.1 mg / kg) and Zn (2.45 mg / kg). Heavy metals Zn and Cu selected as the leaching test parameters on nickel slag and solidification products. <br /> <br /> Leaching of heavy metals is conducted on solidification products to identify potential pollution of heavy metals contained to the environment and human <br /> <br /> health.<p align="justify">
