Surface runoff that flows through the coal stockpile and penetrates the ground can be a source of trace elements that can damage the environment. The trace elements possessed by coal in significant amounts can affect the geochemistry of soil, groundwater and human health, and it has become the concern of PT Bukit Asam Tbk. Port Units. This research aims to identify the effect of coal stockpiles on trace elements in the soil. The method was to take the soil sample around the research area and then performed X-ray fluorescence (XRF) analysis. The data obtained was then displayed in a distribution map of elements which has an anomaly. Based on the XRF test results, six elements, including K, Mn, Cr, Zn, Pb, and Cu, were exceeded the threshold. Based on further analysis, it could be concluded that there were several sources of these elements, including plant fertilizers, ash, and stockpile. The presence of the elements was directly related to stockpiles are Mn, Cr, Zn, Pb, and Cu. © Published under licence by IOP Publishing Ltd.
