SEBARAN TIMBAL PADA TANAH DI AREAL PERSAWAHAN KABUPATEN SIDOARJO

Listin Fitrianah, Agus Rachmad Purnama

Abstract


The existence of this industry in Sidoarjo has the potential to negatively impact the environment, namely the accumulation of heavy metals in paddy fields. The magnitude of the impact that can be caused by the presence of lead heavy metals, research is needed that is expected to provide information related to the concentration and distribution of lead on land in the Sidoarjo Regency. The distribution will later be elaborated by mapping using Geographic Information Systems. The purpose of this research is to identify the potential distribution of lead heavy metals in soil and soil in the Sidoarjo paddy fields and the potential impact of lead accumulation on the environment. Samples taken are soil in the paddy fields, with 18 location points. The method used in the identification of lead distribution in paddy fields in Sidoarjo Regency is survey and laboratory testing, where the pattern of lead content distribution in paddy fields is carried out using spatial analysis with the spline with barrier method Arcgis 10.1. The highest distribution of lead content in paddy fields in Wonoayu District is 0.46 ppm. The highest dominant distribution pattern of lead pollution in paddy fields is Wonoayu, Krian and Taman sub-districts.
