Abstract

DAS Cikao Bagian Hulu meliputi Kecamatan Jatiluhur, Pasawahan, Pondoksalam, Bojong dan Darangdan secara administratif berada di Kabupaten Purwakarta. Setiap tahunnya di wilayah pada DAS ini meningkat jumlah penduduknya. Hal ini berbanding lurus dengan perubahan kondisi tata guna lahan yang menimbulkan permasalahan air pada musim kemarau maupun pada musim hujan, padahal daerah ini merupakan kawasan resapan air bagian utara Gunung Burangrang. Metode penelitian menggunakan metode neraca air Thornthwaite dengan modifikasi dari Todd untuk perhitungan debit run off. Parameter yang digunakan adalah data iklim yaitu curah hujan dan suhu, data tutupan lahan dan data kemiringan lereng. Rata-rata curah hujan 2009-2013 sebesar 3,141.068 mm/tahun. Nilai evapotranspitrasi sebesar 1,759.938 mm/tahun. Nilai debit run off di DAS Bagian Barat sebesar 29,285,386.16 m3/tahun, sedangkan di DAS Bagian Timur sebesar 18,399,878.27 m3/tahun. Kebutuhan air tanah pada DAS Bagian Barat sebesar 2,131,706.06 m3/tahun sedangkan pada DAS Bagian Timur sebesar 1,173,951.52 m3/tahun. Dari hasil perhitungan antara debit infiltrasi dan kebutuhan air, didapatkan bahwa cadangan air tanah pada DAS Bagian Barat sebesar 29,320,434.35 m3/tahun dan DAS Cikao Bagian Timur sebesar 30,218,614.12 m3/tahun. Kekritisan air tanah pada DAS Cikao tergolong kedalam kategori belum kritis terlihat masih banyaknya nilai cadangan air tanah. Namun seiring waktu berjalan, perubahan tata guna lahan dan meningkatnya pertumbuhan penduduk akan mempengaruhi ketersediaan air tanah sehingga perlu dilakukan pencegahan agar kondisi ini tidak memburuk nantinya. Perubahan tata guna lahan yang tidak mementingkan aspek lingkungan akan merusak daerah resapan dan mempengaruhi sumber air. Kebutuhan air tanah yang bertambah perlu diimbangin dengan ketersediaan air tanah yang terjaga.

Abstract

Daerah Aliran Sungai (DAS) Citarik Bagian Hulu secara administratif berada di Kabupaten Bandung dan sebagian Kabupaten Sumedang. Sungai Citarik merupakan anak dari Sungai Citarum yang melewati beberapa daerah seperti Cicalengka dan Rancaekek. Perkembangan wilayah yang pesat didaerah yang dilewati oleh Sungai Citarik ini menyebabkan sering terjadinya banjir saat musim hujan. Banjir yang terjadi didaerah ini selain disebabkan karena perubahan tutupan lahan yang masif juga dipengaruhi oleh faktor alamiah seperti peningkatan curah hujan dan faktor morfologi dari Sungai Citarik itu sendiri. Daerah penelitian dibagi menjadi 20 daerah tangkapan air (catchment area). Tujuan dari penelitian ini adalah untuk mengetahui tingkat kerentanan potensi banjir berdasarkan analisis morfometri. Parameter morfometri yang digunakan yaitu rasio kebundaran (Rc), kerapatan pengaliran (Dd), gradien sungai, dan kemiringan lereng. Parameter tersebut sebagai aspek kuantitatif bentuk lahan. Selain itu, parameter curah hujan dan penggunaan lahan juga digunakan sebagai parameter penentuan kerentanan banjir pada daerah penelitian. Hal ini ditunjukkan dengan hasil analisis karakteristik morfometri pada daerah penelitian memiliki bentuk DAS membundar - memanjang, kerapatan pengaliran sedang, gradien sungai rendah, curah hujan agak rendah, dan kemiringan lereng yang bervariasi dari datar-sangat curam. Terdapat 3 tingkat kerentanan banjir di daerah penelitian yaitu Wilayah Tidak Rentan di sebelah utara dan selatan daerah penelitian, Wilayah Sedikit Rentan pada bagian utara hingga selatan, dan Wilayah Agak Rentan pada bagian barat hingga tenggara daerah penelitian.

Abstract

ABSTRACTThe rapid population and economic growth in Bandung City has driven increased groundwater use, necessitating an understanding of hydrogeological conditions to prevent negative consequences. This study aimed to identify the distribution of subsurface rocks, hydrostratigraphy, and groundwater characteristics in shallow aquifer systems through aquifer geometry modeling and ground-based observations. The model was developed by integrating regional geological data, 22 one-dimensional geophysical points, 7 well logging points, andprevious research results, and analyzed using modeling software and GIS software. Resistivity interpretation reveals aquifer lithology consisting of coarse tuff, lapilli, and tuffaceous sandstone (21–103 Ohm.m), aquiclude lithology consisting of fine tuff, tuffaceous claystone (0–30 Ohm.m), and volcanic breccia (101–350 Ohm.m), and aquifug lithology in the form of lava (>350 Ohm.m). The model shows the dominance of tuff sandstone in the northwest, fine tuff in the northeast, and tuff claystone in the southeast. The model revealed two types ofdeveloped aquifers, unconfined aquifer at a depth of 0–34.08 m (shallow aquifer system) and confined aquifer at 41.75–68.5 m (deep aquifer system). The characteristics of groundwater in the shallow aquifer system are categorized as fresh groundwater with EC values of 183–897 µS/cm, TDS 92–447 mg/l, and pH 5.4–6.86. Spatial distribution analysis of EC, TDS, and pH values is influenced by lithology, topography, and land cover. Vegetation in the upstream area preserves groundwater quality, while the dominance of built-up land and plantations increases EC, TDS, and pH to close to neutral levels. The results of this study emphasize the need for vegetation conservation in the upstream area, control of land use change, and urban spatial planning based on recharge to maintain the sustainability of groundwater resources in shallow aquifer system in the Bandung City area.Keywords: Groundwater, Hydrostratigraphy, Model, Aquifer, Groundwater Characteristic

Abstract

This study investigates the geomorphological characteristics and geological evolution of the Selasari area, Southern West Java, with emphasis on the interaction between lithostratigraphy, tectonic evolution, and karst landscape development. The objectives are to characterize the geomorphological and lithostratigraphic framework, analyze structural control on landscape development, and reconstruct the geological evolution of the area. An integrated approach combining morphographic, morphometric, morphogenetic, lithostratigraphic, and structural characterization from DEM-based interpretation and field observations was applied. The study area is characterized by karst low hills developed on carbonate-dominated lithologies deposited in a shallow marine environment during the Middle–Late Miocene. Structural analyses suggest a dominant NW–SE orientation that may influence drainage development and valley alignment, possibly associated with tectonic activity related to regional subduction processes along southern Java and subsequent uplift during the Plio–Pleistocene. The integration of geomorphological, lithostratigraphic, and structural evidence suggests that the geological evolution of the study area records a transition from shallow marine carbonate deposition to a tectonically uplifted karst terrain. These findings contribute to a better understanding of karst landscape evolution in the Southern Mountains of Java and highlight the importance of integrated geological approaches for understanding structurally controlled karst systems and supporting geological mapping.

Abstract

Population growth is directly proportional to the increasing demand for water, while land-use changes into residential areas also affect the region’s water storage capacity. In Cianjur Regency, residents’ water needs are supplied by the Cianjur and Cibanteng sub-watersheds (Sub-DAS), most of which have undergone land conversion into settlements. This condition highlights the importance of studying groundwater flow systems to ensure the sustainability of water resources. Geologically, the area consists of old volcanic rocks and younger volcanic deposits, with permeability values ranging from 5.789×10⁻³ to 1.8752×10⁻⁷ cm/sec. Based on physical properties, groundwater shows different characteristics within a groundwater basin, EC and TDS values tend to increase downstream, indicating groundwater interaction. Chemically, the groundwater exhibits facies containing Mg-Ca, HCO₃ minerals, suggesting that the groundwater is in a transitional flow phase. The relatively high Mg/Ca ratio indicates that evaporation plays a significant role in controlling groundwater chemistry. The Ca-Mg or Ca/Mg phase forms due to dissolution processes from evaporation and prolonged interaction between water and older rocks. This phenomenon provides important insights into the dynamics of the groundwater flow system in Cianjur. The development of this groundwater flow is crucial for water resource planning and management in Cianjur Regency.
