Abstract

The contamination and characteristic of metals Ni and Cr at the location of soil TPA Antang Makassar on Top Soil layer has been investigated. The sample point is divided into four Lines, two Lines in the direction of groundwater flow (Line A and Line C), two Lines perpendicular to groundwater flow (Line B and Line D). Twelve samples were collected and analyzed using ICP-OES method, at a depth of 0-10 cm, 10-20 cm and 20-30 cm. This study aims to determine the characteristic of soil samples and to study the contamination of heavy metals in the environment of TPA Antang Makassar, South Sulawesi. The results showed that the concentration of metals Ni and Cr on TPA Antang Makassar has spread horizontally, with varying amounts in every depth, on the soil surface (Top Soil). The four TPA sites of Makassar are Line A, Line B, Line C and Line D for each depth, containing heavy metals Ni and Cr, far exceeding the threshold, except metal Cr for Line B at 10-20 cm and 20-30 cm depth in the range of 10 ppm (r = 0,74), still on the threshold set by the government of the Republic of Indonesia and the directorate general of the supervision of drugs and food.
