Abstract

Sarolangun Regency is a district that has the potential for gold metal mineral natural resources. This potential causes many illegal gold mining activities (PETI) in the area. It is also suspected that PETI activities can cause environmental damage and pollution in the activity area and downstream from the PETI location. Environmental pollution that occurs is caused by the disposal of gold processing waste (tailings) into water bodies and groundwater. Waste generated from gold mining activities mainly contains mercury (Hg) and lead (Pb). The purpose of this study was to analyze the level of heavy metal pollutants (Hg and Pb) using the contamination factor (CF), the pollutant load index (PLI), and the geoaccumulation index (I_geo) on former PETI in Sarolangun Regency. The sampling technique was carried out by a purposive sampling technique and the sample taken was soil. Heavy metal concentration data will be calculated using the CF, I_geo, and PLI index formulas.  Hg concentrations were 0.86 mg/kg, 0.77 mg/kg, and 0.80 mg/kg in three sampling areas, and lead concentrations were 0.51 mg/kg, 0.54 mg/kg, and 0.53 mg/kg. Based on the analysis of CF calculations and I_geo, Hg(mercury) has more potential to become a pollutant at the study site (CF>6), (2<I_geo<3). On the other hand, the study site was not polluted by lead based on the CF value and geoaccumulation index. The overall PLI calculation of Hg and Pb stated that the research location was not included in the polluted category with a PLI value <1.

Abstract

The research was conducted on oil palm plantations in Sumber Harapan Village with an area of ​​1,585 hectares of oil palm plantations or 92.66% of the total area of ​​1,710.51 hectares of village. This study was conducted with the aim of knowing the relationship and effect of distance, groundwater level, fertilization dose and time and condition of dug wells on nitrate and nitrite concentrations in the study area and the distribution of nitrate and nitrite concentrations in ground water around oil palm plantations Sumber Harapan Village. Determination of the location of the sample points was carried out using the purposive sampling method. Nitrate and nitrite compound tests were carried out on 15 groundwater sample points using the Palintest 7500 photometer. In the results, 14 units of dug wells (93.33%) are unstandard and 1 unit (6.67%) is following standar based on the Guidelines for Housing and Rural Settlement Development Criteria for PUPR RI number 5 of 2016. The results showed that the highest nitrate concentration was at location S14 at 4.140 mg/l and the lowest nitrate was at location S13 at 0.063 mg/l. The highest nitrite concentration value was at location S4 of 0.028 mg/l and the lowest nitrite was at S14 of 0.000 mg/l. Concentrations of nitrate and nitrite are evenly distributed throughout the study area with a radius of 100 meters from the groundwater sample point. The results showed that the concentration of nitrate and nitrite was still below the quality standard based on the Regulation of the Minister of Health Number 32 of 2017
