Abstract

The increasing demand for clean water in Selebar Subdistrict, Sumur Dewa Village, Bengkulu City has prompted research to identify and map aquifer zones more accurately. This study aims to analyze the presence and depth of aquifers using the Vertical Electrical Sounding (VES) geophysical method, which is then verified using borehole lithological data. VES data collection was conducted at three sounding points (n=3) using a Schlumberger configuration with an AB/2 electrode spacing of 250 m. The acquired geophysical data were processed using IPI2win software with an error value (RMS error) >5%, resulting in a one-dimensional (1D) subsurface model that was further developed into a two-dimensional (2D) cross-section. The results indicate that the main aquifer zone is located at a depth of 51–75 meters, characterized by low resistivity values (<50 Ωm), indicating a water-saturated layer identified as the groundwater zone. This is consistent with drilling data, which show indications of water loss at the same depth interval, thereby reinforcing the assumption of groundwater presence in that aquifer layer. Based on these results, it can be concluded that the integration of the VES geoelectric method, verified with borehole cross-section data, is effective in characterizing subsurface structures and mapping aquifer zones more accurately.

Abstract

Groundwater is an important water resource for meeting community water demands. Information regarding subsurface characteristics and aquifer occurrence is essential for assessing groundwater potential in a given area. This study aims to identify subsurface layer characteristics and determine zones with potential as aquifers in Raflesia Asri Housing Estate, Betungan Village, Selebar District, Bengkulu City. The research employed the two-dimensional (2D) electrical resistivity method using the Wenner configuration. The measured data were processed using Res2DINV software to obtain a subsurface resistivity distribution model. The inversion results indicate resistivity values ranging from 1.52 Ωm to 317 Ωm, with an investigation depth of approximately 43 m. Low-resistivity zones (1.52–15.0 Ωm) are interpreted as clay and silt layers, whereas moderate-resistivity zones (15.0–69.0 Ωm) are interpreted as clayey sand to water-saturated sand, which are considered potential aquifer layers. High-resistivity zones (>69.0–317 Ωm) are interpreted as gravelly sand and weathered rock. The dominance of moderate-resistivity zones in the inverted resistivity sections indicates the presence of potential aquifers that may serve as groundwater resources in the study area.

Abstract

Penelitian ini mengkaji penerapan model pembelajaran mesin untuk mengklasifikasikan perilaku ayam pada kondisi suhu dan kelembapan yang bervariasi, dengan tujuan mengoptimalkan kesejahteraan dan produktivitas unggas melalui pemantauan otomatis. Analisis difokuskan pada perilaku utama seperti Beristirahat, Makan/Minum, dan Aktivitas Fisik, serta meneliti bagaimana fluktuasi lingkungan memengaruhi respons fisiologis ayam, khususnya dalam termoregulasi. Selama periode pengamatan selama 21 hari, data dikumpulkan dari enam ayam menggunakan sensor suhu dan kelembapan, disertai dengan rekaman video. Sebanyak lima model pembelajaran mesin diuji, yaitu Random Forest, Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Multi-Layer Perceptron (MLP), dan metode ensemble, untuk mengidentifikasi model yang paling efektif di antara lima model yang digunakan. Model Random Forest menunjukkan kinerja terbaik dengan akurasi sebesar 98,65%, membuktikan kemampuannya dalam membedakan berbagai aktivitas dengan efektif. Selain itu, temuan penelitian ini menekankan pentingnya mengintegrasikan data lingkungan secara real-time dan meningkatkan teknik ekstraksi fitur untuk meningkatkan keandalan klasifikasi. Wawasan dari penelitian ini berpotensi memberikan kontribusi terhadap pengembangan sistem pemantauan cerdas adaptif, meskipun masih memerlukan validasi lebih lanjut dengan jumlah sampel yang lebih besar, sekaligus menjadi landasan awal yang berpotensi mendukung kemajuan di masa depan dalam manajemen unggas komersial dengan memungkinkan intervensi kesejahteraan yang tepat waktu dan mendukung operasi yang efisien serta berorientasi pada kesejahteraan.

Abstract

The city of Bengkulu is the capital of Bengkulu Province, has a lake called Danau Dendam Tak Sudah (DDTS), which is located in a strategic area due to its potential underground water resources. The purpose of this study was to determine the distribution of aquifers around DDTS, in Surabaya Village, Sungai Serut Subdistrict, Bengkulu City through the geophysical method of Vertical Electrical Sounding (VES) with Schlumberger Configuration. VES measurement points were taken at 21 points. This study was conducted in a residential area to determine whether the subsurface aquifer is connected to water in DDTS. Data acquisition used the MAE X612-EM VHR Multi-Channel Resistivitimeter Geoelectric tool. The results of data acquisition in the field were then processed using Progress, Strater, IP2win and Surfer software. The interpretation results show that the resistivity value, depth and thickness vary as well as the existence of 2 - 5 layers as the geological structure and characteristics of the local lithology with a resistivity value of 2 - 19 Ω.m is groundwater, resistivity value of 19 - 30 Ω.m clay flake, resistivity value of 30 - 70 Ω.m clay, resistivity value of 70 - 100 Ω.m top soil and resistivity value of 100 - 150 Ω.m sandy gravel. Shallow aquifers are estimated to be at a depth of < 20 m, while the deep aquifers are located at > 25 m below the surface and have a thickness of 2 to 78.5 m.
