Abstract

Penelitian ini bertujuan untuk menelaah hubungan antara aktivitas pertambangan dengan kandungan logam berat pada air tanah dengan studi kasus di kawasan pertambangan rakyat Kalurahan Kalirejo, Kokap, Kulon Progo, Daerah Istimewa Yogyakarta. Beberapa logam berat yang umum berasosiasi dengan wilayah pertambangan dengan tipe alterasi hidrotermal adalah arsen (As) dan tembaga (Cu). Kalurahan Kalirejo memiliki kondisi geologi yang ditandai oleh kehadiran batuan intrusi, disertai mineralisasi serta alterasi hidrotermal yang cukup intensif. Selain itu, praktik pertambangan tradisional yang relatif masif di kawasan ini semakin meningkatkan potensi kontaminasi air tanah. Mengingat tingginya ketergantungan masyarakat terhadap sumber air tanah, penting dilakukan kajian mengenai kandungan Cu dan As serta keterkaitannya dengan kondisi geologi setempat. Penelitian dilakukan melalui analisis kandungan Cu dan As pada sampel air tanah, batuan, dan urat kuarsa. Hasil menunjukkan bahwa konsentrasi Cu pada air tanah masih tergolong aman (<2 mg/L) sesuai Permenkes No. 2 Tahun 2023, dengan rentang 0,0027–0,94 mg/L. Sebaliknya, konsentrasi As telah melampaui ambang batas aman (>0,01 mg/L), yaitu 0,0623–0,1287 mg/L. Kondisi pH netral pada air tanah Kalirejo diduga menjadi faktor pengontrol utama kelarutan logam, sehingga As (V) cenderung lebih mudah larut dibandingkan Cu. Konsentrasi As yang lebih tinggi juga ditemukan pada area dengan alterasi argilik dan pelapukan batuan intensif. Oleh karena itu, tindakan remediasi air tanah direkomendasikan, terutama pada wilayah permukiman dengan kadar As tinggi.

Abstract. Prasidya DA, Wilopo W, Warmada IW, Retnaningrum E. 2019. Optimization of manganese bioleaching activity and molecular characterization of indigenous heterotrophic bacteria isolated from the sulfuric area. Biodiversitas 20: 1904-1909. &nbsp;The present research evaluated the manganese bioleaching potency of a heterotrophic bacteria KB3B1. This bacterial strain has been isolated from sulfuric area located at Ungaran, Middle of Java, Indonesia using modified 9K medium by adding of several organic nutrients. The manganese bioleaching activities of the strain was analysed by applying of varying glycine concentrations (0, 5, 10, 15 mg mL-1) with pyrolusite pulp densities of 0.02 g cm-3 on a rotary shaker at 180 rpm for 18 days incubation. Several parameters, including the growth of bacteria, pH values, the concentration of soluble manganese and cyanide, were investigated at the interval of 3 days. Molecular characteristics of the strain were further analyzed based on 16S rDNA gene sequences. After 15 days, the maximum yield of manganese 16.6% was achieved under the addition of 10 mg mL-1 glycine. This maximum extract obtained was followed by the maximum bacterial growth, pH, and cyanide product of the strain. Phylogenetic analysis showed that the strain was closely related with Bacillus niacini EP89. Besides, the average frequencies of guanine and cytosine (G+C) of the strain was in same range as that of the reference bacteria in the GenBank and Bergey's Manual Systematics of Bacteria.

Abstract. Retnanimgrum E, Wilopo W, Warmada IW. 2021. Enhancement of manganese extraction in a biochar-enriched bioleaching column with a mixed culture of indigenous bacteria. Biodiversitas 22: 2949-2955. Biochar can improve manganese ore extraction during bioleaching by inducing redox reactions and providing a porous matrix for bacterial attachment. In this research, the effect of variations in biochar concentration on the performance of a bioleaching column with a mixed culture of Acidithiobacillus sp. KL3 and Bacillus niacini KB3B1 were studied comprehensively for 30 days. Addition of 0.4% biochar resulted in 89% manganese extraction. Bioleaching with biochar promoted the oxidation of sulfur and yielded high sulfate concentrations, much better pH, and excellent oxidation–reduction potential conditions. The bacteria in the mixed culture survived and adapted to the extreme column environment by releasing extracellular polymeric substance, as evidenced by the sharp increase in the content of the material in the column to 135.7 mg/g over 30 days of incubation. The synergistic effect of the bacteria in the mixed culture greatly contributed to the mechanism of manganese extraction in the column, as indicated by changes in relative bacterial abundance, which is related to bacterial community succession during bioleaching. The relative abundance of B. niacini KB3B1 gradually increased and peaked at 30% over 9 days of measurements. By comparison, the abundance of Acidithiobacillus sp. KL3 first decreased over 9 days of bioleaching and then increased to a maximum of 80% in the final stages of the process. This finding reveals that biochar addition could enhance the mechanisms of bioleaching and improve the yield of manganese extraction.
