“…The material used is synthetic acid mine drainage which is made by dissolving FeSO4•7H2O and MnSO4•H2O with the charge of each adsorbate metal is Fe 2+ , and Mn 2+ into1 litter of distilled water with a certain composition that resembles acid mine drainage with concentrations of Fe 41.97 mg/L, Mn 21.75 mg/L, and pH 4 [7,8]. The natural zeolite (mordenite type) used in this research was obtained from Klaten, Central Java.…”

“…Batch adsorption tests were conducted by mixing different quantities (2, 4, 6, 8, 10 g) of natural zeolites with 100 mL of synthetic solutions containing heavy metal ion concentrations of Fe 41.97 mg/L and Mn 21.75 mg/L [7]. The mixture was then stirred using a water bath shaker for 24 h. The final concentration of the heavy metal ions in the aqueous phase was then determined using Atomic Absorption Spectrophotometry (AAS).…”

The environmental problem that often occurs in coal mining is acid mine drainage which can pose a serious threat to human health, animals and ecological systems. Acid mine drainage contains heavy metal contaminants such as iron and manganese. The purpose of this study was to determine the adsorption equilibrium carried out using natural zeolite adsorbents type mordenite from Klaten, Central Java. The application of natural zeolite with a volume of 100 mL synthetic acid mine drainage with concentrations of Fe 41.97 mg/L, Mn 21.75 mg/L and variations in dose of natural zeolite (2, 4, 6, 8, and 10 grams). The highest percent removal was at a dose of 10 grams of zeolite resulted in % removal of 97.94 % for Fe and 67.81 % for Mn. The results obtained using Langmuir and Freundlich adsorption isotherms. The results followed the Freundlich isotherm model with an adsorption parameters Kf = 0.427 mg/g, R2 = 0.991, n = 1.610 Fe metal and Mn metal adsorption parameters are Kf = 0.006 mg/g, R2 = 0.9971, and n = 0.578

“…From the remediation perspective, acidic soil pH increases heavy metal uptake by plants (Jaskulak et al 2020). In this environment, agronomic practices have been developed to increase remediation by adjusting pH and adding ameliorants like chelates, fertilizers, and composts (Iqbal and Baig 2016;Khodijah et al 2019;Utami et al 2020). For example, the phytoremediation of mercury-contaminated soils using Cyperus kyllingia increased maize production to 126% higher than on untreated land (Muddarisna and Siahaan 2014).…”

Abstract. Muryani E, Sajidan, Budiastuti MTS, Pranoto. 2023. Diversity and potential of herbaceous plants as mercury (Hg) hyperaccumulators in small-scale gold mining sites in Pancurendang, Banyumas, Indonesia. Biodiversitas 24: 3378-3386. Plants resistant to mercury can be used as an alternative to processing gold mining waste with the phytoremediation method. The study aimed to inventory herbaceous plant species in artisanal and small-scale gold mining (ASGM) sites in Pancurendang Village (Banyumas, Central Java, Indonesia), measure mercury concentrations in plants and root zones, and analyze the potential of herbaceous plants as mercury (Hg) hyperaccumulators. Herbaceous plants were cataloged by purposive sampling with multiple quadrats of 2m x 2m in 14 locations and then analyzed to obtain density, frequency, dominance, importance value, and diversity index. Biomass and Hg concentrations were measured from selected herbaceous plants and soil samples of the root zone. The Biological Accumulation Coefficient (BAC) was calculated to determine the plants' potential as Hg hyperaccumulators. Plant inventory identified 54 herbaceous plant species belonging to 26 families, with Paspalum conjugatum P.J.Bergius being the dominant species. In the root zones, Hg was found at 11-73 ppm and 7.6-85.36 ppm in 19 species. Ipomea aquatica Forssk. accumulated the highest concentration (85.36 ppm) and absorbed the greatest amount of Hg (5.25 mg). Based on their BACs, the nineteen species were categorized into moderate to high (hyper) accumulators, with Plectranthus sp. having the highest BAC of 4.54.

Air asam tambang adalah limpasan air yang terbentuk dari proses oksidasi mineral sulfida yang terekspos dengan udara di atmosfer dan bercampur dengan air. Air asam tambang dapat berasal dari proses penambangan terbuka, pengelolaan batuan buangan, penimbunan batuan dan pengelolaan limbah tailing. Pencemaran air asam tambang di badan air penerima terjadi karena pengolahan air asam tambang yang kurang tepat. Permasalahan pencemaran air asam tambang dapat menimbulkan masalah lingkungan dan kesehatan masyarakat. Contoh kasus pencemaran air asam tambang di badan air yaitu pencemaran air asam tambang dari industri pertambangan batu bara yang terjadi di Sungai Palakan, Kalimantan Timur yang telah berlangsung lebih dari dua dekade. Pengolahan eksisiting yang diterapkan yaitu pengendapan TSS pada settling pond industri tambang batu bara. Pengolahan lanjutan yang direkomendasikan setelah melalui unit settling pond yaitu constructed wetland. Constructed wetland memanfaatkan simbiosis yang berlangsung secara alami antara tumbuhan air dengan mikroorganisme pada media di sekitar sistem perakaran (rhizosfer). Tujuan dari kajian ini adalah menganalisis penerapan metode constructed wetland untuk mengolah air asam tambang sehingga kualitasnya memenuhi baku mutu saat dilepas ke badan air penerima. Debit air asam tambang yang diolah yaitu 0,84 m 3 /detik yang diolah pada CW berukuran 8,04 ha. Tumbuhan yang dipilih adalah eceng gondok dengan tipe tumbuhan single plant dan tipe kolam sub-surface flow arah aliran horizontal. Kebutuhan tumbuhan eceng gondok yaitu sejumlah 322.160 tumbuhan yang ditanam pada 4 kompartemen berbeda. Kualitas efluen air asam tambang setelah diolah dengan constructed wetland memenuhi baku mutu dan aman untuk dilepas ke badan air penerima.
