“…This is because soil stripping activities and the groundwater hydrological cycle also indirectly contribute to the Fe fluctuations of acid mine drainage. If stripping is carried out continuously, the Fe content will naturally increase, as well as during the rainy season, the Fe content will increase [4,6]. The Fe element of acid coal mine water in the other 9 locations (ST1,ST2,ST3,ST4,ST5,ST6,ST7,ST8 and ST9) has not met the feasibility because it has a value above 1 mg/L.…”

“…Therefore, we will switch from a water treatment system that uses the oxidation of manganese compounds to compounds that are insoluble in water and are easy to physically separate, using a high-order oxidation method. Although Mn in the compound MnCO 3 , Mn(OH) 2 has a valence of two, the substance is relatively difficult to dissolve in water but for compounds such as MnCl 2 , MnSO 4 has a large solubility in water [3,6].…”

“…Fe 0.3 ppm, Mn 0.0440 ppm, Cd 0.1195 ppm. High concentrations of Fe, Mn, and Cd metals do not exclude the possibility of other metals [6,7] The measured pH value in the input sample is 4.5. Acidic pH values are caused by excessive rock removal, coal mining and waste that expose soil/rock containing sulfide minerals including pyrite and marcasite.…”

One of the coal mining corporations is in charge of environmental management, which includes managing water resources One of the coal mining corporations is in charge of environmental management, which includes managing water resources. The management of coal mine water that has the potential to become polluted water can be processed into fresh water in a sustainable manner. This indicates that acidic water from coal mines is still handled as waste that must be addressed once more. According Ministry of Health Regulation No. 416 1990 on Water Quality Requirements and Monitoring (Indonesian Government Regulation Ministry of Health related to water quality requirements and water quality monitoring), the purpose of this study is to evaluate the viability of coal mine acidic water quality in comparison to Fe (iron), Mn (manganese) ions, and pH parameters as fresh water. According to the findings of this study into acid mine drainage, the pH of the water in nine study areas in Pucok Reudeup Village, a former coal mining region, is low. The findings of this study on acid mine drainage demonstrate that the pH of the water at nine research sites in Pucok Reudeup a village near a disused coal mine. In nine research locations in Pucok Reudeup Village, a former coal mining area, the pH of the water did not exceed the established freshwater quality requirements (pH water below 6.5 - 9), according to the findings of this acid mine drainage study. Fe parameters that fulfilled the quality requirements were only present at five research sites. High iron concentrations result from Fe 2+ or Fe 3+ ions that cannot obtain oxygen from the environment as well as from the stripping of soil and rocks that are predominately composed of iron minerals, necessitating further management such as aeration. All study sites' Mn (manganese) parameters continue to fall short of the quality requirements outlined in No. Minister of Health Regulation 416 of 1990 Requirements on water quality No. Minister of Health Regulation 416 of 1990 Requirements on water quality and monitoring, that is, always exceeding the quality standard by 0.5 mg/L, except for stations 4, 5 and 6 There are 3 locations of Mn (manganese). In general, it can be concluded that the Fe and pH parameters of the study area still do not meet the freshwater quality standards. While Mn partially meets freshwater quality standards atstations (4, 5 and 6). Stations 1, 2, 3, 7, 9 are always higher than fresh water quality standards. The problem of acid mine drainage requires environmentally friendly water treatment.

“…Water treatment is currently carried out conventionally such as coagulation, flocculation, sedimentation and filtration. Currently water treatment can be carried out using membrane technology (specifically nanofiltration and / or reverse osmosis) [Hidayah et al, 2018;Kiswanto et al, 2020]. Drinking water treatment that has been implemented in Indonesia in the form of conventional treatment consists of Coagulation-Flocculation, Sedimentation and Filtration.…”

Acidic water from the coal of mining pool has been polluted from the surrounding coal stockpile stocpile industry. Water quality in mining ponds can threaten the biota in it. During this time, coal mining pool the local community uses water extensively for everyday requirements like drinking, washing, and bathing. More than time it turns out that coal mine acidic water has been polluted. This problem needs to be sought a solution, one of which is required treatment technology for creating water quality that satisfies requirements for drinking water quality. This research tries to use NF270 membrane type Nanofiltration membrane technology to eliminate COD, TSS, TDS, and metal parameters (Fe, Mn). This research was conducted by analyzing the influence pressure (4, 5, and 6 bar) on each component's rejection rate and flux each parameter. The results of the study show the processed results as follows;

“…Minimizing heavy metals can be done by membrane filtration, electrodialysis, chemical precipitation, exchange, ions, and adsorbs (Ahalya et al, 2003;Ismail & Moustafa, 2016;Kiswanto, Susanto, et al, 2020;Kiswanto et al, 2021). Heavy metal removal can also be done by coagulation, fluctuation, flotation, electrochemical treatment, ion chelating (Noor et al, 2019).…”

The young coal mining pits (young pits) found in West Aceh cause many problems. These pits that form ponds have the potential to be utilized for aquaculture activities. However, the main problem faced in the young pits is the high content of heavy metals. This makes the ponds dangerous for fish farming. Hazardous heavy metals in coal mines are Pb and Fe. Humic acid is one of the materials that can be used to minimize heavy metals and increase water pH. The use of humic acid is more efficient because this technology is easy and cheap and the raw materials are abundant. Humic acid acts as a substance of cation exchange ability found in compost. This research has a long-term goal of making humic acid contained in compost as an alternative material that can minimize heavy metals Pb and Fe, so that it can be used for fish farming activities. The specific objective is to determine the best capacity (dose of humic acid) in minimizing heavy metals and increasing the pH of young pond water in former mines and its effect on fish farming. This research method used a completely randomized design consisting of one factor, namely the dose of humic acid (0 g/L, 2.5 g/L, 5 g/L, 7.5 g/L) and three replications. The results showed that humic acid was able to minimize the content of heavy metals Pb and Fe in coal mine water with the best dose of 5 g/L. The percentage reduction produced was more than 90%. The results of fish rearing using ex-mining pond water treated with humic acid showed that the survival rate and growth rate of fish were higher.
