Abstract

Coal mining activities could potentially interfere with the environment. One of the environmental disturbances in coal mining activities is theformation of acid mine drainage (AMD). AMD management can be done passively through the construction of swamp forest. The constructed swampforest system uses organic material in the form of cow manure which serves as a growing plants’ medium. Phytoremediation is an attempt to usevplant species in the accumulation of heavy metals. This study was aimed to know the AMD management system passively and identify the diversity ofplants in artificial swamp forests. Purposive sampling method with a sample size of 2 x 2m in 10 plots/compartments was used to identify the plantdiversity in constructed swamp forest. The observation was made both before and after AMD flowed. Constructed swamp forest consist of 6compartments (2 sediment pond compartments and 4 swamp compartments). The results of the vegetation analysis found that before the AMD flowed,21 species are still capable growing naturally in constructed swamp forest, however, it became 15 after the AMD flowed. Cyperus iria, Fimbristylisgriffithii, Scirpus juncoides, Ludwigia hyssopifolia, Cyperus platystylis and Monochoria vaginalis are six dominant species that can be used asphytoremediation agent in constructed swamp forest.Keywords: Acid Mine Drainage, constructed swamp forest, phytoremediation

Abstract

One of the biggest challenges in coal mining activities is the successful management of degraded land through post-mining revegetation activities in accordance with applicable regulations. An easy way to assess the success of revegetation can be done with the approach of the physical properties of the soil. This study aims to evaluate post-mining revegetation land management by analyzing soil physical properties in the form of permeability and bulk density associated with plant growth. The research method was carried out by taking a predetermined sample in the plot area with a size of 20 x 20 m in each revegetation land planted with three depths are 0-20 cm, 20-40 cm, and 40-60 cm. The results showed that the success of revegetation land showed a positive increase where the growth of Acacia mangium plant height had reached 56.5% and the growth of the stem diameter of the plants had reached 53.8% when compared with the same plant type on the original revegetation land (HTI) according with the physical properties of the soil in the form of permeability which shows an increase and bulk density which shows a decrease approaching the value of the HTI land conditions. Thus, the success of post-mining land revegetation can be determined by the physical properties of the soil that affect the growth of the plant.

Abstract

Terbentuknya air asam tambang  (AAT) merupakan salah satu dampak dari adanya aktifitas pertambangan. Air asam tambang memiliki ciri pH asam berkisar antara 3-5, warna air kuning kemerahan, dengan konsentrasi besi (Fe) dan mangan (Mn) yang tinggi. Penyisihan Mn menjadi tantangan tersendiri karena mangan hanya dapat disisihkan jika konsentrasi Fe AAT kurang dari 5 mg/L. Teknologi yang kini dikembangkan untuk menyisihkan Mn air asam tambang adalah sistem lahan basah buatan (LBB). Kinerja LBB dipengaruhi oleh debit AAT. Untuk mengetahui efesiensi penyisihan mangan (Mn) dan nilai pH pada LBB, maka pada penelitian ini digunakan Lahan Basah Buatan Aliran Permukaan (LBB-AP) berdimensi 150cm x 50 cm x 75 cm beraliran kontinyu dengan variasi debit. Pada penelitian ini akan divariasi debit AAT yaitu D0 7,1 mL/menit; D1 8,8 mL/meni; D2 10,5 mL/menit, dan D3 12,2 mL/menit. Hasil penelitian menunjukkan peningkatan pH terbaik pada D0 7,1 mL/menit periode ke 4 dengan nilai pH 4,3. Kemampuan penyisihan Mn terbaik pada LBB D0 7,1 mL/menit periode ke 1 sebesar 3,3 mg/L dengan efisiensi sebesar 62%. Kata Kunci : air asam tambang, lahan basah buatan aliran permukaan, mangan, variasi debit. The formation of acid mine drainage (AAT) is one of the impacts of mining activities. Acid mine water has a characteristic low water pH ranging from 3-5, the color of reddish-yellow water, and has high concentrations of iron (Fe) and manganese (Mn). Mn removal is a challenge because manganese can only be removed if the concentration of Fe AAT is less than 5 mg / L. One of the technologies that can be used to remove Mn from acid mine drainage is the constructed wetland system (CW). CW performance is influenced by AAT debits. To determine the efficiency of removal of manganese (Mn) and the pH value in CW, then in this study used Surface Flow Constructed Wetland (SFCW) with dimensions of 150cm x 50 cm x 75 cm with the continuous flow with variations in debit. In this study, AAT debit will be varied, namely D0 7.1 mL / min; D1 8.8 mL / min; D2 10.5 mL / min, and D3 12.2 mL / min. The results showed the best pH increase at CW D0 7.1 mL/min for the 4th period with a pH value of 4.3. The best Mn removal ability at CW D0 7.1 mL/min in the first period was 3.3 mg / L with an efficiency of 62%. Keywords: Acid mine drainage, Debit variation, Manganese, Surface flow Constructed Wetland.

Abstract

Salah satu permasalahan yang terjadi pada saat penambangan batu bara adalah terbentuknya air asam tambang, yaitu air hujan atau air tanah yang tercampur dengan batuan yang mengandung sulfida tertentu yang ada di dalam batubara melalui proses oksidasi, sehingga air tersebut bersifat sangat asam dan biasanya mengandung zat besi serta mangan dengan konsentrasi yang tinggi. Tanaman Gempol yang bisa menetralisir kandungan asam dan logam yang ada di air, sehingga air yang telah tercampur dengan zat-zat hasil pertambangan bisa digunakan kembali untuk keperluan sehari-hari. Penelitian ini bertujuan  menganalisis daya hidup kemampuan tumbuh tanaman Gempol pada lahan yang mengandung air asam tambang dan kemampuan tanaman Gempol dalam menyerap logam berat khususnya Fe dan Mn. Penelitian dilakukan di lahan pascatambang di areal swampy forest PT.Jorong Barutama Greston (PT JBG) merupakan perusahaan tambang batubara dengan sistem penambangan terbuka yang terletak di Desa Swarangan, Kecamatan Jorong, Kabupaten Tanah Laut, Provinsi Kalimantan Selatan.

Abstract

Acid mine drainage (AMD) is the result of mining, especially coal mining, generally open-pit mining. Any open pit mining will produce voids filled with acid mine drainage (AMD) which is water formed due to the oxidation of sulfide minerals that are exposed or exposed to the water in the presence of water. One of the highly reactive sulfide minerals in the AMD formation process is pyrite. This is a challenge for the environment how to absorb heavy metals contained in water. Here the researchers tried to use the method of Phytoremediation. Phytoremediation is a technology that uses plants, here the researcher uses bangkal plants (Nauclea Subdita Merr.) which are planted in different locations, namely unflooded land, temporarily inundated, and flooded. The purpose of this study was to test the ability of the pods to adapt and grow on post-mining land. Analyzing the quality of life of Bangkal on post-mining land with non-flooded, temporarily inundated and permanently inundated land conditions. Knowing the effect of soil fertility and inundation factors on the growth of bangkal. Analyzing the content of heavy metals Fe and Mn that accumulate in plant parts (roots, stems and leaves). The results of this study indicate that Bangkal plants are able to survive in temporarily flooded land and are able to absorb heavy metals contained in acid mine drainageAir asam tambang (AMT) merupakan dampak hasil dari penambangan khususnya pertambangan batubara, umumnya pertambangan terbuka. Setiap pertambangan terbuka akan menghasilkan void yang diisi oleh air asam tambang (AAT) merupakan air yang terbentuk akibat oksidasi mineral sulfida yang terpajan atau terdedah di udara dengan kehadiran air.

Abstract

Coal mining by the open-pit mining method creates the formation of a pit lake. The ex-mining site, over time, was gradually filled with contaminated water and must be returned to the water quality standard of compliance level. With proper treatment, the pit lakes have the potential for several benefits and subsequent uses. This study aimed to analyze the existing condition of the Paringin Pit Lake at South Kalimantan by identifying the quality of the water flow, and it is compliance with the parameter threshold values. The results showed that the pit lake water management had been carried out supported by good management of the catchment area and was indicated the stable category by geology technical study. The success of its revegetation processed in the area was shown by an erosion study in which the result was a very low-level category. No less important is the management of runoff water both in the quantity of water balance control and consistent water quality treatment to meet the quality standard values that have been set. The Paringin Pit Lake water management strategy is a form of activity that demonstrates compliance with good and responsible mining principles to support sustainable development that can serve as a good reference and example for other mining activities in terms of mine closure preparation.
