Abstract

An important problem that often occurs due to open pit mining activities from coal mining is the problem of acid mine drainage. Acid mine drainage is formed due to the oxidation of sulfide minerals that are exposed to the outside and then mixes with water, resulting in acidic water and also acid mining water often contains suspended solids that have high concentrations. This acidic mining waste can cause corrosion and dissolve metals so that contaminated water is toxic and can destroy aquatic life. Handling of acid mine drainage as passive treatment with constructed wetland methods is often applied to acid mine drainage treatment in several coal mining companies. By applying the method of constructed wetlands in the handling of acid mine drainage, it is effective in increasing the pH value and reducing the dissolved heavy metal content. This research is to find a management method for acid mine drainage using the constructed wetland method, so it is reviewed again to assist the management process of acid mine drainage by passive treatment with the constructed wetland method. The review was conducted to compare the management method of acid mine drainage with the constructed wetland method and to find out the advantages and disadvantages of swamp plants used in the artificial wetland method.

Abstract

Undang-Undang No. 3 Tahun 2020 tentang Perubahan Atas Undang-Undang Nomor 4 Tahun 2009 Tentang Pertambangan Mineral Dan Batubara telah mengamanatkan kepada Pemegang Izin Usaha Pertambangan untuk menerapkan kaidah Teknik pertambangan yang baik (Good Mining Practice) yang salah satunya wajib melaksanakan penerapan upaya konservasi mineral dan batubara. Konservasi minerba merupakan upaya dalam rangka optimalisasi pengelolaan atau pemanfaatan sumber daya mineral dan batubara secara terukur, efisien, bertanggung jawab, dan berkelanjutan. Objek yang menjadi target pengelolaan penerapan konservasi mineral dan batubara sesuai Lampiran VII Kepmen ESDM No. 1827 K/30/MEM/2018 meliputi recovery penambangan, recovery pengolahan, batubara kualitas rendah, mineral kadar rendah, mineral Ikutan, sisa hasil pengolahan dan pemurnian, serta cadangan marginal. Pada tahun 2020, Direktorat Jenderal Minerba telah menetapkan Keputusan Direktur Jenderal Minerba Nomor 182.K/30/DJB/2020 tentang Petunjuk Teknis Pelaksanaan Konservasi Mineral dan Batubara dalam rangka Pelaksanaan Kaidah Teknik Pertambangan Yang Baik sebagai pedoman untuk pelaku usaha pertambangan dalam pelaksanaan pengelolaan konservasi mineral dan Batubara. Terdapat istilah baru dalam aspek konservasi yaitu cadangan marginal dimana pengertian cadangan marginal sudah dimasukkan didalam SNI (Standard Nasional Indonesia) 5015-2019 tentang Pelaporan Hasil Eksplorasi,Sumberdaya dan Cadangan Batubara.Sebagai bentuk kepatuhan perusahaan kepada pemerintahan perlu dilakukan metodologi bagaiamana cara menentukan cadangan marginal tersebut sehingga diharapkan adanya peningkatan dan upaya untuk mengelola serta memanfaatkan cadangan marginal batubara agar seluruh sumberdaya yang ada dapat dioptimalkan untuk dilakukan kegiatan penambangan sehingga dapat memberikan nilai tambah bagi pengusaha dan juga pemerintah.

Abstract

Groundwater is water that flows in the sub-surface where the formation is called aquifer. The groundwater can be found tens or even hundreds of meters below the surface. On the other hand, layers that allow water to pass easily are called permeable layer, but impermeable has no ability to pass the water. Gravel, sand, pumice, and cracked rock are examples of the permeable. Clay or loam layers are examples for impermeable layer. Furthermore, according to its location, groundwater can be divided into shallow groundwater (phreatic groundwater) and deep groundwater (aresthetic groundwater). The shallow groundwater located above an impermeable layer with depth of 15 to 40 meters. The deep groundwater is commonly found between two impermeable layers with depth of more than 40 meters. This paper focused on the ground water exploration through resistivity geoelectric method. Moreover, the configuration in the method used was Schlumberger and Wenner-Schlumberger configuration. The combination of these two configurations provided a relatively high resolution picture finding the aquifer for both horizontally and vertically.

Abstract

Water is an essential resource for human being and the needs significantly increases from time to time. The highly demand of water may cause water scarcity. Based on that condition, groundwater exploration is urgently needed, where at least the location and depth of the groundwater can be identified through an accurate method. Geoelectric, on the other hand, is a geophysics method that is commonly used for identifying geology structures, including for groundwater exploration or identification. The objectivity of this research was to compare the geoelectric configuration accuracy, which Schlumberger, Wenner, Wenner-Schlumberger, Dipole-dipole, and Pole-pole were discussed. As a result, configuration of Wenner amd Wenner-Schlumberger showed the best results based on the vertical resolutiuon, the CST, and the sounding parameters.
