Abstract

Regional spatial planning requires accurate data according to the planning scale. One of the problems encountered in the analysis of spatial planning in Indonesia is the unavailability of some basic data that have a level of detail according to planning needs, including geological data. RTRWK requires a map at a scale of 1:50,000, while the availability of a Geological Map at a Scale of 1:50,000 from the Ministry of Energy and Mineral Resources is still very limited. This study aims to produce surface geological distribution data and its characteristics needed in spatial planning with a morphological analysis approach. Detailed morphological analysis is carried out by processing Digital Elevation Model data with a spatial resolution of 8 meters. Detailing of the morphological classification is carried out on the BMB classification. Morphological interpretation is carried out in stages by dividing the land surface from general to detailed, producing classes of high ridged hills, low ridged hills, undulating valleys between hills and plains. Landform interpretation is carried out by adding geological structure data and rock types in the analysis, producing landform classes of high hills elongated fault zones, low hills elongated fault zones, undulating valleys between hills in fault zones, and alluvial plains. Landform units of elongated hills of fault zones can be detailed based on the relief pattern and slope gradient into ridge, steep slope, and gentle slope. Low hills elongated fault zones can be divided into ridge and gentle slope. Meanwhile, the undulating valleys between the hills of the fault zone and the alluvial plains do not show any further variations. The andesite breccia rock unit is the lithology that forms the morphology of elongated ridged hills, the undulating valleys between the hills are formed from andesite breccia colluvium rock units, while the alluvial plains are formed from alluvium rock units. The division of detailed morphology in the hills reflects the differences in the characteristics of the degree of weathering of the rocks and the weathering materials. The andesite breccia rock unit on the ridge experiences strong weathering and produces a lot of in-situ soil material. The andesite breccia bedrock exposed on steep slopes experiences early weathering with thin soil deposits on top and has several andesite boulders deposited in the bends of the slopes. Gentle slopes have surface rock units dominated by colluvium material. This unit consists of andesite breccia boulders scattered on the surface mixed with weathered soil material from ridge and/or steep slopes. The undulating valleys between hills also have characteristics of surface rock units consisting of andesite breccia boulders on the land surface with thick soil resulting from the accumulation of weathered soil from the hills. Alluvial rock units on alluvial plains do not reflect significant variations.

Abstract

Mercury contamination caused by artisanal gold mining waste would become an environmental problem if there were no remediation actions. This study aimed to investigate the ability of natural zeolite obtained from Gunungkidul Yogyakarta to stabilize mercury in mining waste or tailing. Tailing samples were obtained from three locations on Kulon Progo, Wonogiri, and Banyumas, and the natural zeolite sample was obtained from Gunungkidul, Yogyakarta. The batch experimental study was conducted to test the ability of the effectiveness of natural zeolite in stabilizing mercury in tailing. The result of the study shows that the natural zeolite used in the experimental study can be used to reduce the mercury concentration in tailing. The natural zeolite's ability for stabilization varies and depends on the initial mercury concentration in tailing and the natural zeolite dose.

Abstract

Soil contamination was commonly found in gold mining location in Selogiri, Wonogiri, and Central Java and need serious attention for remediation action. This study aimed to investigate the mineralogical characteristic of zeolitic tuff and to analyze the influence of its characteristic for lead sorption on soil in mining, as mentioned earlier location. The soil sample was obtained from around the gold mining location. The zeolitic tuff was obtained in two locations in Gunungkidul, Yogyakarta: A and B. Zeolitic tuff samples were then characterized for mineralogy content using polarization microscopes, cation exchange capacity (CEC) by using barium chloride method and XRD (X-Ray Diffraction) analysis. A batch test was conducted on a laboratory scale by shaking zeolitic tuff samples with soil samples in a CaCl2 solution. The solution was then shaken using a magnetic stirrer, and the filtrate was sampled at a specific time interval. The batch test result showed that the zeolite mineral percentage influenced the sorption behavior of zeolitic tuff in the sample and the value of CEC, which the more zeolite mineral and CEC value, the higher of sorption capacity achieved up to 58.8%. Hence, zeolitic tuff investigated in this study has a promising material for the remediation of Pb-contaminated soil in Selogiri, Wonogiri, and Central Java.

Abstract

Abstrak Air tanah merupakan sumber daya penting yang menopang kebutuhan domestik, pertanian, dan aktivitas ekonomi, namun tekanan terhadap keberlanjutannya semakin meningkat akibat perubahan penggunaan lahan dan pertumbuhan penduduk. Kota Batu sebagai wilayah hulu Daerah Aliran Sungai Brantas memiliki banyak mata air yang bergantung pada sistem akuifer vulkanik, salah satunya Sumber Banyuning yang dimanfaatkan secara intensif oleh masyarakat. Penelitian ini bertujuan untuk mengkaji kondisi geologi dan hidrogeologi serta menentukan zona perlindungan Mata Air Sumber Banyuning sebagai dasar pengelolaan sumber daya air tanah yang berkelanjutan. Penentuan zona perlindungan dilakukan melalui metode zonasi mata air yaitu hidrogeologi, manual, solusi analitik, serta kombinasi ketiga metode tersebut. Hasil penelitian menunjukkan bahwa wilayah penelitian tersusun atas tiga satuan litologi utama yaitu andesit Anjasmoro, andesit Arjuno Welirang, dan breksi gunung api Arjuno Welirang. Aliran air tanah bergerak dari barat laut menuju tenggara mengikuti kemiringan topografi sehingga daerah imbuhan berada di bagian barat laut. Berdasarkan analisis tersebut ditetapkan empat zona perlindungan, yaitu Zona I dengan radius 10 m dan luas 121 m2, Zona II dengan radius sekitar 336 m dan luas 0,136 km2, Zona III dengan radius sekitar 2,56 km dan luas 4,24 km2, serta Zona Imbuhan dengan luas minimal 5,63 km2 yang terletak hingga sekitar 4,32 km dari mata air. Analisis penggunaan lahan menunjukkan bahwa zona perlindungan didominasi oleh hutan, lahan perkebunan, dan sebagian permukiman yang berpotensi memengaruhi proses infiltrasi dan kualitas air tanah. Oleh karena itu, pengelolaan dilakukan melalui pengaturan aktivitas pada setiap zona, yaitu perlindungan ketat di Zona I, pembatasan penggunaan bahan kimia dan penanaman vegetasi pada Zona II, pengendalian aktivitas pencemar pada Zona III, serta pelestarian tutupan hutan pada zona imbuhan. Penetapan zonasi ini diharapkan dapat mendukung konservasi air tanah dan menjaga keberlanjutan Mata Air Sumber Banyuning di Kota Batu.Abstract Groundwater is an important resource that supports domestic, agricultural, and economic activities; however, increasing pressure on its sustainability has emerged due to land use change and population growth. Batu City, located in the upstream area of the Brantas River Basin, contains numerous springs associated with volcanic aquifer systems, one of which is Banyuning Spring that is intensively utilized by local communities. This study aims to examine the geological and hydrogeological conditions and to determine the protection zones of Banyuning Spring as a basis for sustainable groundwater resource management. The delineation of spring protection zones was conducted using a spring zoning approach including hydrogeological analysis, manual methods, analytical solutions, and a combination of these approaches. The results show that the study area consists of three main lithological units, namely Anjasmoro andesite, Arjuno–Welirang andesite, and Arjuno–Welirang volcanic breccia. Groundwater flow moves from northwest to southeast following the regional topographic gradient, indicating that the recharge area is located in the northwestern part of the study area. Based on this analysis, four protection zones were established, namely Zone I with a radius of 10 m and an area of 121 m2, Zone II with a radius of approximately 336 m and an area of 0.136 km2, Zone III extending about 2.56 km with an area of 4.24 km2, and a recharge zone with a minimum area of 5.63 km2 located up to approximately 4.32 km from the spring. Land use analysis indicates that the protection zones are dominated by forest, plantation areas, and limited settlements that may influence infiltration processes and groundwater quality. Therefore, management strategies are implemented by regulating activities in each zone, including strict protection in Zone I, restriction of chemical use and vegetation planting in Zone II, control of potential contaminating activities in Zone III, and preservation of forest cover within the recharge zone. The delineation of these zones is expected to support groundwater conservation and maintain the sustainability of Banyuning Spring in Batu City.Submitted:2025-12-17 Revisions:2026-03-02 Accepted:2026-03-09 Published:2026-03-10

Abstract

Artisanal and small-scale gold mining (ASGM) activities still use mercury (Hg) for the amalgamation processing step. These ASGM activities generate tailings as a mining by-product, representing the primary source of environmental Hg contamination. The purpose of this study was to investigate Hg concentrations in several tailing ponds and analyze the fractionation of Hg in tailings in ASGM on Banyumas District, Central Java, Indonesia. In total, 15 tailings samples were taken from the ASGM tailings storage pond in the study area, and then the total Hg concentration was measured using cold vapor atomic fluorescence spectrometry (CVAFS). Hg fractionation was also performed using CVAFS. The results showed that the total Hg concentration in the tailing pond was very high, exceeding the normal background levels in rock or sediment due to ASGM activities. The fractionation analysis conducted to determine Hg mobility showed that almost all samples were concentrated in the first and second fractions, which had negative environmental effects. The findings from the mercury speciation analysis highlight the critical need for enhanced monitoring of gold mining operations and for implementing responsible tailings management strategies to prevent environmental pollution and protect ecosystem health in the study area.
