Abstract

This research aims to present a comprehensive overview of the distribution of rock layers and inform the presence of rock layers that function as aquifers (water-carrying layers) in the Wolonmaget Village area, Wolonmaget Sub-district, Alok Barat District, Sikka Regency, East Nusa Tenggara, using the method of geolectric. This research type is field research (in situ test) and uses quantitative data by directly collecting data or test samples in the field at 3 (three) observation points: GL1, GL2, and GL3. This study result show that the area being investigated through geoelectric estimation has provided a description of the rock layer conditions, both vertically and laterally. The hydrological conditions in the study area are included in a local productive aquifer system with rocks that are expected to act as aquifers, specifically Tuff Sand. Based on the geoelectric investigation, the aquifer layers identified are: GL.01 at a depth of 73.66-200.000 meters with a thickness of 138.36 meters; GL.02 at a depth of 61.64-200.000 meters with a thickness of 138.36 meters; GL.03 at a depth of 61.22-2000 meters with a thickness of 138.78 meters.

Abstract

The diversity of physical and chemical properties of subsurface layers makes geotechnical information essential in the early stages of construction planning, particularly for underground works such as pipeline routes. The heterogeneity of soil conditions can pose technical risks if not properly anticipated. The resistivity geoelectrical method is a non-destructive investigation technique that provides a depiction of subsurface resistivity distribution, helping to effectively and efficiently identify geological characteristics and soil structure. This study aims to examine the application of the resistivity geoelectrical method in identifying soil conditions as a technical basis for planning underground pipeline routes in Semarang City, Central Java. The survey was conducted at 24 observation points (GL 01–GL 24) using a quantitative approach and field experiment method. Data collection was carried out through direct measurements using specific electrode configurations to obtain resistivity values at each observation point. The interpretation results show variations in resistivity values that reflect differences in subsurface materials, such as clay, sand, and hard rock layers. These findings are used to assess excavation difficulty, potential landslides, and the likelihood of groundwater presence along the planned pipeline route. Thus, the use of the resistivity geoelectrical method has proven to provide detailed spatial information and supports safer and more efficient underground pipeline construction planning.

Abstract

Penelitian ini mengkaji peran pembelajaran Bahasa Arab dalam membentuk pilar akhlak siswa di MDTA Al-Iftitah, Kampung Cileguk, Desa Ciengang, Kecamatan Gegerbitung. Pembelajaran huruf hijaiyah (Alif Ba Ta) tidak hanya diarahkan pada penguasaan aspek linguistik, tetapi juga menjadi sarana internalisasi nilai moral dan religius yang memperkuat karakter Islami peserta didik. Melalui metode pembelajaran yang integratif, siswa tidak hanya terampil membaca dan menulis huruf Arab, melainkan juga terdorong untuk meneladani akhlak Rasulullah SAW (1). Kajian ini berdasarkan hasil observasi, wawancara, serta evaluasi pembelajaran yang menunjukkan adanya keterkaitan erat antara penguasaan bahasa, pembiasaan nilai Islami, dan proses pembentukan akhlak mulia.

Abstract

This study aims to analyze the relationship and compatibility between the Standard Penetration Test (SPT) N-value and soil classification based on the Unified Soil Classification System (USCS). The SPT is commonly used to determine in-situ soil density and consistency, while the USCS provides a comprehensive classification of soil types through grain size distribution and Atterberg Limits parameters. Data were collected from six different depth intervals, consisting of N-SPT values, grain size analysis (gravel, sand, silt, clay), and Atterberg Limits (LL, PL, IP). The results indicate that all soil samples are classified as high-plasticity clay (CH) according to the USCS, characterized by Liquid Limit (LL) values ranging from 70.45% to 86.83% and Plasticity Index (PI) values from 38.91 to 49.26. The N-SPT values range from 2 to 21, representing soil conditions from very soft to medium dense. Despite the variation in N-SPT values, the soil classification remained consistently within the CH group, dominated by fine-grained materials with high plasticity. These findings suggest that the N-SPT values describe relative soil strength but are not sufficiently sensitive to reflect variations in fine-grained soil characteristics, which are primarily controlled by plasticity and mineral composition. The study concludes that the direct correlation between N-SPT values and USCS classifications is not linear for high-plasticity cohesive soils. Therefore, the interpretation of soil conditions in CH-type soils requires an integrated approach that combines field testing (SPT) with laboratory analyses (grain size and Atterberg Limits). This highlights the importance of a comprehensive geotechnical evaluation to achieve a more accurate understanding of soil behavior. Keywords:N-SPT, USCS, Atterberg Limits, grain size analysis, CH soil, soil classification.
