Abstract

The consumption of fluoride below the safe limit can result in dental caries, while high concentrations can lead to fluorosis, which can potentially impair the body's systems. One geological factor that influences the concentration of fluoride in water is the type of rock through which the water passes, including granite and its weathering products. The area is located within the Tandjungbuku Formation, which is predominantly composed of granite rock and contains several areas with Mining Business Permits (IUP) for commodities such as silica sand. This research serves as a form of mitigation in response to mining activities, post-mining, and the development of an industrial area. One anticipated impact is an increase in fluoride concentration in the research area, originating from both natural geological processes and human activities. The investigation involved geological mapping, petrographic analysis, XRD, and XRF analysis. Water sampling was conducted for both surface water and groundwater from wells in Resang Tandjungbuku Village. The research area consists of two rock units: granite, which acts as a non-aquifer layer, and colluvial deposits, which function as a free aquifer. Petrographic analysis identified minerals associated with fluoride, such as plagioclase, amphibole, and biotite. This was supported by XRD analysis with the presence of biotite, muscovite and kaoline minerals. XRF results revealed fluoride values in granite rock at 0.23% or 2300 ppm, further confirming granite as a source of fluoride. Analysis of fluoride in surface water showed values ranging from 0.01 to 4.24 mg/L, while groundwater consistently had a value of 0.01 mg/L.

Abstract

Lake Toba is one of the prioritized conservation lakes in Indonesia, crucial for domestic needs, tourism, fisheries, agriculture, and power generation. However, Lake Toba’s water levels and discharge have declined in recent decades. This study aimed to enhance water recharge and the water level of Lake Toba through hydrological modeling using the SWAT analysis and regional and specific conservation measures. The SWAT analysis utilized input data, including climate, soil, geomorphology, land use, and hydrology, to generate both existing and post-conservation water balance models. Conservation methods were categorized into civil engineering and vegetative approaches. Vegetative conservation techniques included agroforestry and MPTS (Multi-Purpose Tree Species), while civil engineering methods encompassed terracing, trenching, and infiltration wells. Regional conservation focused on land use plant types, while specific conservation involved detailed classification of the Lake Toba watershed by slope class, plant type, and land use. The analysis revealed significant land use changes in the Lake Toba catchment area, with dry fields increasing from 72,961 ha to 125,000 ha, a decrease in water level from 905 to 903 m above sea level, and a reduction in discharge from 180 m³/s to 125 m³/s. SWAT analysis shows that the existing inflow to Lake Toba is 131 m³/s (with 78% accuracy), with potential increases to 250 m³/s due to regional conservation and 180 m³/s due to specific conservation. Conservation efforts have also improved discharge rates across 39 sub-watersheds of Lake Toba, both monthly and annually.

Abstract

With its abundant groundwater potential, East Java faces a growing risk of contamination due to rapid industrial growth. This study assessed groundwater quality in four regional groundwater basins (GWB) using the Water Quality Index (WQI), water quality standard comparison, Piper diagram, and hydrogeochemical ion analysis. The WQI analysis revealed that 59% of the samples were classified as excellent and good for consumption, predominantly found in volcanic, river alluvial, and limestone hill areas. In comparison, 11% were unsuitable for consumption due to contamination, particularly near coastal, industrial, and agricultural zones. The Piper diagram showed that most groundwater samples were unpolluted, reflecting the natural interaction between groundwater and surrounding lithology. However, ion standard comparison identified samples exceeding acceptable ion levels, and ion correlation analysis confirmed contamination from industrial, agricultural, anthropogenic, and municipal wastewater activities. These findings highlight the need for targeted groundwater management, particularly in areas vulnerable to contamination.

Abstract

Sustainable groundwater availability depends on the optimal functioning of recharge zones, particularly in spring catchments that supply clean water. This study delineates groundwater recharge zones in the 81 km² Cokro Spring catchment, Klaten Regency, using an integrated approach combining Vertical Electrical Sounding (VES) geophysical data with a GIS-based Analytical Hierarchy Process (AHP). Eight parameters were analyzed: lithology, rainfall, land use land cover, soil, drainage density, groundwater level, slope, and topography. The resulting recharge map was validated using Receiver Operating Characteristic (ROC) analysis, incorporating both spring observation points and random data points. Results indicated three recharge categories: good (38%), dominated by lapilli tuff and fractured lava, moderate (35%), located in the western fine tuff zone, and poor (27%), in the central area characterized by massive lava and built-up land. Land use changes from 2019 to 2022 revealed increased settlements and reduced infiltration areas, which contributed to a decline in recharge potential. Groundwater levels from 2012 to 2025 decreased at all measurement points, likely driven by LULC changes and increased abstraction. The study demonstrated the effectiveness of the integrated VES-AHP-GIS approach for mapping recharge zones, providing a scientific basis for targeted groundwater conservation and sustainable resource planning in volcanic catchments.

Abstract

Aspek geologi lingkungan memegang peran penting dalam perencanaan wilayah. Penelitian ini mengevaluasi beragam parameter geologi, terutama terkait airtanah dan sifat permukaan, untuk memperkuat pengembangan wilayah Desa Bejiharjo di Kecamatan Karangmojo, Kabupaten Gunungkidul. Parameter yang diteliti meliputi kedalaman muka air tanah dan Total Dissolved Soil (TDS), yang diperoleh dari sumur gali dan hanameter, serta karakteristik tanah dan batuan yang didapatkan melalui pemetaan. Temuan penelitian memaparkan tiga zona kedalaman muka air tanah (dangkal <6 m, dalam 6-20 m, sangat dalam >20 m), dua zona TDS (excellent <300 mg/L, good 300-600 mg/L), serta dua zona satuan permukaan (zona tanah dan batuan). Zonasi pengembangan kawasan ditentukan melalui pembobotan setiap parameter dan pengklasifikasian skor yang membaginya menjadi zona sangat mampu, mampu, dan kurang mampu. Zona yang dianggap cocok untuk pengembangan adalah zona mampu dan sangat mampu yang menunjukkan variasi karakteristik lahan dengan kedalaman muka air tanah antara <6 m hingga >20 m, permukaan yang terdiri dari campuran tanah-batuan, dan nilai TDS antara <300 hingga 600 mg/L. Sebaliknya, zona kurang mampu diisi dengan kedalaman air tanah dari 6 m hingga >20 m, permukaan yang merupakan tanah residu, dan nilai TDS antara <300 hingga 600 mg/L. Dominasi tanah residu menjadi faktor utama yang mengkategorikan zona ini sebagai zona kurang mampu karena tanah residu memiliki kualitas pondasi yang kurang dibandingkan dengan batuan.

Abstract

Salah satu akibat pembangunan infrastruktur dan penambahan pemukiman adalah perubahan fungsi lahan di Kota Semarang. Terjadinya perubahan fungsi lahan akan berakibat pada proses peresapan air ke dalam tanah yang berdampak salah satunya adalah banjir. Tujuan penelitian ini adalah mengevaluasi tingkat kekritisan resapan air di Kota Semarang. Metode penelitian diawali dengan menentukan paramater yang mempengaruhi resapan air di daeah penelitian. Parameter yang digunakan dalam penelitian ini meliputi jenis tanah, tata guna lahan, kemiringan lereng, dan litologi, dankemudian dilakukan pembuatan peta-peta tiap parameter. Setelah itu, dilanjutkan dengan pembobotan tiap parameter dengan menggunakan metode Analytical Hierarchy Process (AHP). Selanjutnya, dari hasil pembobotan dilakukan pembagian zonasi tingkat kekritisan resapan air di daerah penelitian. Hasil penelitian menunjukkan bahwa zonasi daerah resapan air yang berada di Kota Semarang termasuk dalam zona sangat kritis, kritis, agak kritis, mulai kritis, normal alami, dan baik. Hasil penelitian ini diharapkan dapat dijadikan referensi dalam pembuatan kebijakan dalam rangka konservari air tanah maupun mitigasi bencana banjir yang kerap kali terjadi di sebagian daerah penelitian.
