Abstract

Soil is a material consisting of mineral fractions and organic matter that undergoes weathering to form a horizontal layer or a cross section of the soil profile. Soil can cause heavy metal content that comes from waste pollution, use of fertilizers and can be seen based on the age of the plant. Lead is a very toxic heavy metal, the optimal content in the soil ranges from 0.5 to 3.00 ppm. This study aims to determine the content of heavy metal lead (Pb) in soil and coffee cherries, as well as some soil chemical properties such as CEC, pH, and C-Organic Soil located in Sukananti Village, Muaradua Kisam District, Ogan Komering Ulu Selatan District. The method used in this study is a very detailed method using a 1: 5,000 scale work map. The area of land used in this study was 15 ha with sampling divided into 5 locations which were carried out using Stratified Random Sampling based on the age of the plants. The results showed that the lead (Pb) content in the soil had crossed the threshold, which ranged from 14.12–16.06 ppm with an average of 14.98, while the lead (Pb) content in the coffee cherries could not be read or was below the detection limit of the tool. ie with a value of <0.0002 ppm. The results of the research suggest to farmers to balance the use of organic fertilizers and the use of inorganic fertilizers containing phosphate so that the content of Lead (Pb) in the soil decreases.
