Abstract

Drought poses a significant threat to water supply in regions like Kulon Progo, Indonesia. Seasonal water shortages lead to agricultural losses and increased disaster vulnerability. This study aims to improve groundwater exploration method for drought mitigation by analyzing the correlation between lineament density and groundwater using a dataset of 127 observations from Samigaluh and Kalibawang subdistricts using Pearson Correlation. The research uncovers a non-linear threshold at 4 km/km². Below the threshold, groundwater occurrence increases with density (r = 0.949), shows increasing infiltration. But above the threshold, occurrence decreases (r = -1.000), suggesting over-fracturing reduces storability. Maximum depths follow a similar pattern (r = 0.883 below, r = -1.000 above). These findings challenge conventional scoring methods in groundwater potential zoning, which often assume a linear positive relationship with lineament density. The study provides a novel framework for targeted exploration, prioritizing moderate-density zones to mitigate drought impacts and build resilience against climate-induced disasters.

Abstract

Seawater intrusion occurs when seawater enters aquifer systems, which happens a lot in coastal areas. The coastal zone of Tugu District, Semarang City, Central Java Province, is one such area where groundwater becomes increasingly vulnerable due to intensified pumping and land-use changes near the shoreline. This study aimed to ascertain the incidence of seawater intrusion in the western coastal region of Semarang and to examine its characteristics and sources using an integrated geological, hydrogeological, geophysical, groundwater geochemical, and stable-isotope analysis approach. A descriptive quantitative method was employed, including the measurement of 59 geological/hydrogeological sites, four geoelectrical soundings, and the acquisition of 14 groundwater samples from wells and springs. The parameters examined encompassed physical properties  (EC, TDS, pH), chemical composition (Cl?, Na?/Cl? ratio, Cl?/SO?²? ratio, Simpson index, and BEX), facies classifications using Piper diagrams, and stable isotope ratios (?¹?O and ?²H). The results showed that several locations, especially along the coast of Mojorejo and Mangkang Wetan Villages, had EC values exceeding 10,000 µS/cm and Cl? concentrations above 4,000 mg/L. Chemical ratios suggested that salinization processes are still active. Piper diagrams indicated that alkali-chloride type predominated in coastal areas. Isotope analysis showed that groundwater and seawater mixed. These findings demonstrated that the effects of intrusion have damaged shallow aquifers in the alluvial region. Managing coastal groundwater requires the stringent implementation of conservation zones, restrictions on borehole extraction, and the use of geoindicators for monitoring. A multidisciplinary approach remains essential for fully understanding seawater-intrusion dynamics in tropical coastal environments.

Abstract

Kota Makassar yang berkembang pesat banyak menghadapi tantangan pemenuhan kebutuhan air bersih, terutama dari air tanah yang secara kualitas lebih baik. Di wilayah pesisir, pemanfaatan air tanah yang berlebihan dapat memicu intrusi air laut, yang menyebabkan penurunan kualitas air tanah di beberapa daerah di Kota Makassar. Penelitian ini menggunakan metode GALDIT yang dimodifikasi dengan menambahkan parameter kepadatan penduduk untuk menilai kerentanan air tanah terhadap intrusi air laut. Hasil penelitian menunjukkan bahwa wilayah pesisir Makassar memiliki dua tipe akuifer, yaitu akuifer bebas pada bagian atas yang tersusun dari pasir dan pasir lempungan, serta akuifer semi tertekan di bagian bawah yang tersusun dari batupasir, batupasir lempungan, dan batupasir tufan. Aliran air tanah bergerak dari daerah tinggian di tenggara menuju barat laut, dengan daerah pembuangan di laut Selat Makassar. Terdapat tiga zona kerentanan air tanah: tinggi, sedang, dan rendah. Zona kerentanan tinggi ditemukan di Kecamatan Mariso, Wajo, dan Tallo, yang dipengaruhi oleh genangan air laut akibat reklamasi pantai dan interaksi suplai air sungai dengan air tanah di daerah muara. Analisis menunjukkan bahwa kepadatan penduduk adalah parameter paling signifikan dalam menentukan kerentanan, diikuti oleh muka air tanah, jarak dari garis pantai, konduktivitas hidraulika, tebal akuifer, tipe akuifer, dan dampak status intrusi.

Abstract

Landslides are one of the major hazards in volcanic areas, causing loss of life, property damage, and degradation of the environment. The western slopes of Mount Lawu, a stratovolcano in Central Java Province, Indonesia, are especially prone to landslides because of steep topography and increasing human activities. The rapid population growth and land use changes, driven by tourism and agricultural expansion, have increased the vulnerability of the area. This study examines the performance of the weight of evidence (WoE) method in mapping landslide susceptibility over the western slopes of Mount Lawu, with a focus on the interaction between environmental factors and land use. The parameters considered in this research include slope, lithology, distance from lineaments, roads, and rivers, rainfall, and land use. The spatial datasets used included a digital elevation model (DEM) at a scale of 1:16,000, as well as slope, river, lineament, and land-use data at a scale of 1:25,000, and lithology data at a scale of 1:50,000. All of these datasets were processed and analyzed using ArcGIS Pro. The WoE analysis resulted in the landslide susceptibility map, which divided susceptibility into four classes: high, moderate, low, and very low. The model achieved an accuracy of 0.81, demonstrating strong predictive capability. The landslide susceptibility map showed high-risk zones along steep slopes, near rivers, and close to roads, particularly in northern Ngargoyoso and western-southern Tawangmangu Districts. These results highlight the utility of the WoE method for developing the landslide susceptibility map with good accuracy. A landslide susceptibility map can be used to evaluate existing land use and to create spatial planning-based landslide disaster risk reduction.

Abstract

Groundwater is the primary water resource used for domestic, industrial, and agricultural needs for the community in the Yogyakarta-Sleman Groundwater Basin area. The urbanization rate has increased since the 1970s and has made massive use of groundwater, causing environmental problems, including the quality and quantity of groundwater. Therefore, this study aimed to investigate the spatiotemporal groundwater fluctuation trends based on the non-parametric Mann-Kendall test and recharge rate estimation using the water table fluctuation (WTF) method. The groundwater level data were collected from monitoring wells across the study area during 2018-2022, particularly emphasizing 8 wells representing recharge, transition, and discharge areas. The results showed that the groundwater fluctuation pattern generally followed the season. During the rainy season from January to April, groundwater reached the shallowest level and began to decline gradually when it entered the dry season from May to October. Groundwater recharge rate was estimated to vary from 171.49 to 1,505.56 mm/year. Meanwhile, the Mann-Kendall test showed that most of the Yogyakarta-Sleman Groundwater Basin area did not experience significant fluctuation trends, except for two monitoring wells in the center of Yogyakarta City which had increasing groundwater level trends. The rising groundwater levels were expected to be caused by urban wastewater recharge. This study has provided a new description and insights into spatiotemporal changes in the groundwater table and the quantification of groundwater recharge.

Abstract

A landslide is a process where the mass of rock or soil that forms a slope moves due to the force of gravity in a weak area. Landslides that occurred in Noelmina Village, Takari District, Kupang Regency on February 17, 2023, resulted in the main road, which connects the provincial capital of East Nusa Tenggara and several districts on Timor Island, being completely damaged. This research aims to identify the factors that contribute to landslides in Noelmina Village. This research began with collecting regional geological data, a regional geological structure, then continued with primary data collection in the field for geological mapping, geomorphological, and land use data, while rainfall data was taken from the CHIRPS satellite data. Results indicated that the landslide occurred within the Bobonaro carbonate mudstone unit, characterized by a rather steep slope where the geological structure consisted of joints in the rock mass. Additionally, the landslide was situated in an area influenced by the regional geological structure, specifically the left-hand horizontal fault. The land use conditions of the research area are quite varied, but the areas that experienced landslides were located in forest land uses that directly border residential areas and roads. The rainfall conditions during the landslide in February 2023 had a high intensity of 431mm - 463mm. An XRD analysis was conducted on rock or soil samples from the landslide area, and it was found that expansive minerals, namely montmorillonite, illite, and kaolinite, were present. The results of this research indicate that landslide events in the research area were significantly influenced by factors such as rock/soil conditions, geomorphology, geological structure, land use conditions, and the presence of expansive clay minerals. Furthermore, the dominant factor triggering the landslide was the high-intensity rainfall that took place in the study area of less than one month.

Abstract

Penelitian terdahulu terkait kualitas air tanah di Kota Gorontalo, umumnya masih bersifat lokal, deskriptif, tanpa mengaitkannya dengan unit geomorfologi Kota Gorontalo. Oleh karena itu, makalah ini bertujuan untuk mengaitkan karakteristik kualitas air tanah dengan unit geomorfologi menggunakan pendekatan Sistem Informasi Geografis (SIG). Data kualitas air tanah yang digunakan adalah sifat fisik-kimia berupa Total Zat Padat Terlarut/TDS, Daya Hantar Listrik/DHL, warna, bau, rasa dan pH. Data diperoleh dari 63 titik sumur gali, sedangkan unit geomorfologi hasil interpretasi DEMNAS dan observasi lapangan. Semua parameter direklasifikasi berdasarkan standar baku mutu air minum dan digabungkan secara spasial untuk menghasilkan peta kualitas air tanah Kota Gorontalo. Hasil penelitian menunjukkan nilai TDS >300 mg/L dan DHL >750 µS/cm ditemukan pada satuan perbukitan intrusi, piroklastik, karst, dataran danau, dan pantai. Sebaliknya, nilai TDS dan DHL yang sesuai standar ditemukan pada dataran aluvial dan banjir. Nilai pH >8,5 diidentifikasi pada dataran pantai dan beberapa titik lokal di dataran aluvial. Peta kualitas air tanah menunjukkan gradasi dari zona air tanah layak menuju zona air tanah cukup layak dan zona air tanah tidak layak sejalan dengan perubahan unit geomorfologi. Air tanah dengan kualitas terbaik terkonsentrasi pada unit geomorfologi dataran aluvial dan banjir di bagian utara dan timur Kota Gorontalo, yang termasuk dalam kategori layak. Secara keseluruhan, penelitian kualitas air tanah di Kota Gorontalo dipengaruhi oleh kombinasi kondisi geomorfologi, interaksi air dengan batuan sekitar, serta keterbatasan pengimbuhan lokal. Pendekatan integrasi berbasis SIG ini dapat diterapkan di kota-kota tropis lainnya sebagai dasar perencanaan konservasi zona resapan dan pengendalian pencemaran air tanah.

Abstract

Landslide susceptibility map is crucial in disaster risk management and it can be used for regional development plans. Landslide susceptibility map can be made by analyzing parameters that are assumed to affect landslides such as gradient slopes, geology, soil, and climate. Selection of landslide controlling parameters influences the accuracy of landslide susceptibility map. This study evaluates the effect of parameter that’s rarely used which is groundwater. The study area of this research was Kalibawang and Samigaluh Subdistricts, Kulonprogo, Special Region of Yogyakarta, Indonesia. Frequency ratio was used for the method along other parameters which is slope gradient, lithology, lineament density, land use, soil thickness. The result shows that groundwater parameter increase the accuracy by 22,29%. This study suggest that groundwater should be highly considered in landslide susceptibility mapping. In the other hand, groundwater depth mapping remains a challenge because most remote sensing method only detect shallow groundwater. Further research is necessary to develop better method for groundwater mapping using remote sensing or other indirect method.

Abstract

Industrial expansion and the increasing use of groundwater in Kendari City have heightened the risk of water table decline and seawater intrusion, particularly in areas adjacent to Kendari Bay. This study aims to assess and map the vulnerability to seawater intrusion in the Kendari Bay region using a modified GALDIT method, supported by field observations and hydrogeochemical analyses for validation. The results indicate that zones with very low to low vulnerability are predominantly located in the western part of the study area, which is characterized by higher topographic slopes. In contrast, areas with very high to high vulnerability are concentrated along the coastal zone, where elevations are relatively low and proximity to the shoreline increases exposure to seawater intrusion. Validation through field and chemical data confirmed the reliability of the vulnerability zoning, as wells situated in high-vulnerability zones consistently exhibited seawater intrusion signatures, whereas those in low-vulnerability zones showed typical freshwater characteristics.
