Abstract

Coal is one of the commodities that is widely used to meet energy needs in Indonesia, which is 38% of the total national energy. Mining activities do not always spur the country's economic prosperity, but can also have a negative impact on the environment. One of the problems caused by mining activities is the formation of acid mine drainage that can disrupt aquatic ecosystems, reduce surface water quality, and pollute the soil. Not only does acid mine drainage contain a low pH, but acid mine drainage also contains heavy metals such as iron, manganese, and sulfate. These heavy metals cause the amount of nutrients in the soil to increase, resulting in reduced soil fertility. The potential of acid mine drainage needs to be known so that preventive and management measures can be taken. Acid mine drainage management is carried out during mining activities and after mining activities have been completed. Acid mine drainage management can be carried out in two ways, namely active treatment and/or passive treatment. Therefore, an evaluation of acid mine drainage management is carried out so that the quality of acid mine drainage that will be channeled to surface water (river) meets the quality standards.
