Abstract
The Tamangapa Antang landfill located in the Antang Subdistrict is the center of Landfill for all regions in Makassar city. Waste processing techniques at Antang Landfill Makassar City South Sulawesi Indonesia use the Open Dumping system so that it has the potential to pollute the surrounding soil. Research has been conducted on the distribution of heavy metals Cu, Pb and Zn in the soil around the Antang landfill. The study aims to analyze the potential spread of heavy metals to the soil around the Antang Landfill. The sampling point is divided into four Points, two Points in the direction of ground water flow (Point A and Point C), two Points perpendicular to groundwater flow (Point B and Point D). Soil sampling is done with depth 0 to 10 cm, 10 to 20 cm and 20 t0 30 cm. Total soil samples analyzed by heavy metal element by Atomic Absorption Spectroscopy method, were twelve samples. The results showed that Cu heavy metals concentration was at the highest level. Followed by heavy metal Zn, where the highest concentration is detected at Point A and Point D, its concentration has exceeded the threshold, except at Point B and Point C, its concentration is still below the threshold permitted by the Government of Indonesia and General of Drug Control and food. While for heavy metal Pb at Point A, Point B and Point C, the concentration is still below the threshold, since it was in the rainy season when samples were taken, that is why the concentration of Pb heavy metal decreased.
