Abstract

Open-pit coal mining as done by the coal mining site Melak have a impact on the surrounding natural environment. The impact of mining operations is that the land becomes unproductive and erosion is very high because of loosing its vegetation on ex-mining land. Vegetation influence the sensitivity of the soil to withstand destruction and transportation by rain and surface runoff and the occurrence of landslides. Analysis of soil erodibility factors seen from the physical-chemical properties of soil is one of the causes of erosion by using organic element parameters, soil structure, permeability, texture. The observation location was carried out on the disposal slope and low wall in-pit that has been revegetation with the hydroseeding technique. This research was carried out by making a design of erosion and sedimentation plots in the form of a zinc boundary measuring 2 x 2 m2, each box divides into three columns. The division of three columns in each box is done to get representative repetition data. Taking soil samples is carried out in each box using a sample ring.

Abstract

Coal mining activities often cause environmental challenges, one of which is acid mine drainage (AMD) with low pH and elevated concentrations of heavy metals and suspended solids. This study aimed to assess water quality improvement through a constructed wetland system using Purun tikus (Eleocharis dulcis) and palm oil empty fruit bunch compost (TKKS). Laboratory-scale experiments were conducted with five treatment variations and three replications over a 20-day retention period. Results indicated that the media combination, with or without limestone addition, significantly altered the water quality parameters. The pH increased from 3.35 to 7.76; TSS decreased from 1,373.3 mg/L to 151 mg/L; Fe decreased from 33.15 mg/L to 2.68 mg/L; and Mn decreased from 7.06 mg/L to 0.45 mg/L over 20 days. These results indicate the potential of constructed wetlands using native plants and organic materials as an environmentally friendly strategy for treating mining wastewater.
