Abstract
The Study has been conducted on the distribution of heavy metal content of manganese (Mn) on landfill in Antang Makassar. The study aims to determine the presence of heavy manganese metal (Mn) in the landfill of Antang Makassar waste landfill. There are 4 lines namely line A sampling points (A0, A5 and A10), line B sampling points (B0, B5 and B10), line C sampling points (C0, C5 and C10) and line D sampling points (D0, D5 and D10) with a depth of (0-10, 10-20 and 20-30) cm. Total samples analyzed by heavy metal elements using ICP-OES method were 36 samples. The concentration of heavy metal manganese (Mn) in Antang landfill soil has spread horizontally. The results of the analysis showed the presence of heavy metal content of manganese (Mn) in the soil in the Makassar Antang waste landfill, where the samples with the highest heavy metal content were, line A sampling points (A0, A5 and A10) each depth (0-10, 10-20 , 20-30) cm. Line C sampling point C10 at depths (0-10 and 10-20) cm, i.e. sequentially (1660 and 1710) ppm. Line D sampling points (A0, A5 and A 0), except, at the sampling point D0 at a depth of 20-30 cm which is 1460 ppm is still below the normal limit, which is allowed by the Government of the Republic of Indonesia and the General of Drug and Food Control as a pollutant inside soil. Soil pH varies from 4.82-6 and is acidic. Soil pH significantly affects the solubility and mobility of metals, because most metals dissolve in acidic soils. The level of pollution of heavy metal manganese (Mn) for line A, line C and line D at the sampling points (A0, A5 and A10) at depths (0-10, 10-20 and 20-30) cm are included in the category of heavily polluted because the concentration of heavy metals manganese (Mn) contained in the soil far exceeds a predetermined threshold. So that necessary remediation of appropriate prevention to prevent risks to humans and the environment.
