Abstract

PT Semen Baturaja, a cement production company in South Sumatra, Indonesia, holds a Mining Business License of 103.4 hectares, of which 64.23% was reclaimed during 2017–2021. However, the revegetation success rate remains low at only 9%, potentially due to excessive soil chromium (Cr) accumulation. This study investigates the application of electrokinetic remediation to reduce Cr concentrations and improve soil conditions for revegetation. The experiment was conducted on soil samples collected from Disposal Area 4 of PT Semen Baturaja, using a laboratory-scale setup with copper electrodes powered by a 20 V direct current, applied continuously for 48 hours. The results showed that Cr ions tend to migrate toward the anode due to electromigration, while redox reactions influence Cr distribution over time. The highest treatment efficiency was observed in segment one (11.123%), and the lowest in segment three (1.651%). These findings demonstrate the potential of electrokinetic remediation as a viable method for enhancing revegetation in Cr-contaminated post-mining soils.

Abstract

Mining activities can lead to the accumulation of heavy metals in soil, particularly lead (Pb), which poses risks to ecosystems and human health. PT Semen Baturaja Tbk has implemented revegetation as a post-mining reclamation strategy, but the success rate remains low, potentially due to high Pb concentrations in the soil. This study investigates the effectiveness of electrokinetic remediation in mobilizing Pb ions in ex-mining soil using aluminum electrodes under a 20 V direct current over treatment durations of 24 and 48 hours. Soil moisture was maintained at 900 ml, and Pb concentrations were measured using X-Ray Fluorescence (XRF). The results indicate that Pb²⁺ ions migrated towards the cathode, with a significant accumulation observed after 48 hours. However, an increase in Pb concentration near the anode was also detected, likely due to Pb oxidation at the anode plate, leading to remobilization of Pb into the soil. These findings highlight both the potential and limitations of electrokinetic remediation for in-situ heavy metal removal in post-mining land reclamation.
