<title>Abstract</title> This study integrates geoelectrical resistivity inversion, geostatistical analysis, and clustering techniques to improve subsurface characterization in Cikole, Lembang, West Bandung Regency. The primary objective is enhance resistivity-based zonation for groundwater exploration by employing a dipole-dipole array with 10-meter electrode spacing, followed 2D inversion visualize distributions. Geostatistical interpolation using Kriging effectively captures spatial...

(Dipresentasikan dalam acara SNIP ITB 2019, 9 Juli 2019. Makalah ini merupakan manuskrip preprint untuk Proceedings SNIPS Saat makalah berstatus: under review) Sejak dipopulerkan oleh F. Stuart Chapin Jr pada tahun 1957, konsep tata guna lahan perkotaan sudah menyinggung unsur-unsur terkait geologi. Meningkatnya jumlah penduduk dunia yang tinggal di pun menjadikan geologi makin dibutuhkan memastikan kota berkelanjutan. Penelitian dilakukan mengetahui bagaimana telah dimanfaatkan perkotaan....

Both natural and anthropogenic coastal landforms characterize Penang Island. As years have passed it is a challenge to differentiate the genuineness of landmasses created by geological formations or reclamation projects. An account given environmental impact solid wastes used for reclaiming land in areas major sewage outfall western channel. Leaching heavy metals was shown be one main sources contamination from wastes. This paper presents eight lines ground penetrating radar (GPR) surveys...

Abstract Fischer plots find extensive applications in paleoenvironmental studies as visual depictions of sea and lake-level fluctuations. They graphically represent the linearly adjusted alterations cumulative thickness sedimentary cycles a specific geographical region over time, with respect to either cycle number or depth strata. The observed successive intervals sediment deposition erosion, that are driven by fluctuations rates subsidence level. Previous researchers have introduced...

Abstract The ongoing investigation into the microfacies and diagenesis of Setul limestone reveals a considerable expanse formation that remains relatively unexplored. comprehension diagenetic processes within sedimentary rocks holds paramount significance in predicting their viability as hydrocarbon reservoirs, decoding geological history depositional environment given region, reconstructing past climatic conditions, understanding fossil record. To meet stipulated research objectives, which...

A combined iso-potentiometric mapping and hydrochemistry study was conducted in the Walini urban area to assess quality suitability of groundwater for domestic other purposes regarding Walini’s development. The direction flow is northeast-southwest, based on observations from 22 water tables between 2022 2023. Groundwater samples obtained dug wells, bore springs were analysed determine physicochemical parameters (EC pH) concentrations major ions. result indicates that freshwater. It contains...

Nenering Formation is essentially made up of semi-consolidated sediments, which are divided into basal conglomerate beds, conglomeratic sandstone, cross-bedded and siltstone to muddy layers facies. It overlie unconformable the Berapit Formation, but conformable Kroh Grik Formations. The stratigraphy a fining upwards sequence where thickness beds become thinner thicker for sandstone. varies from 0.5 m tenths meters. more sandy in upper portion (cross-bedded sandstone) with thin mudstone clast...

The amounts of structural data available from the East-West Highway Route 67 Baling Area have been used to unravel characteristics Semanggol Formation, which comprises black mudstone, sandstone, tuffaceous tuff, paraconglomerate, siliceous shale and chert. area was cut by two sets faults trending NW-SE NE-SW. main fault in this is known as Bok Bak that moderately steeply dips (40 o -88 ) compared conjugate faults. Two folds NE-SW were also identified area, where most them are symmetrical...

New oil data is 21st century jargon. This movement has not been widely echoed in Indonesia. Although some initiatives should be recognized and appreciated, the status of availability reusable most countries, especially Indonesia still low. Most published Indonesian open access journals are form pdf files that cannot reused. We advise editors scientific to consider adopting FAIR sharing by encouraging authors share their as additional a machine readables format, e.g. csv or xls. effort will...
