Abstract

Kecamatan Babahrot mempunyai tata gunalahan yang diperuntukkan sebagai area perkebunan sawit dan pemukiman penduduk. Potensi akan terjadinya pencemaran airtanah sangat memungkinkan dikarenakan penggunaan pupuk pada area perkebunan sawit dilakukan secara terus menerus. Kualitas dan kuantitas airtanah menjadi penting untuk diperhatikan, mengingat airtanah merupakan sumber utama kehidupan makhluk hidup. Studi kerentanan airtanah menggunakan metode GOD (Groundwater Occurrence, Overlaying Lithology and Depth Of Groundwater) berdasarkan data resistivitas dan hidrogeologi memiliki peran yang sangat penting dalam studi pencemaran airtanah. Metode GOD dalam studi kerentanan intrinsik airtanah dilakukan pada 3 jenis parameter meliputi tipe akuifer, tipe akuitar, dan kedalaman muka airtanah. Penggunaan metode GOD dilakukan dengan tujuan untuk dapat memetakan zonasi potensi kerentanan airtanah terhadap pencemaran di lokasi penelitian. Berdasarkan pengamatan dilapangan diperoleh hasil kondisi hidrogeologi di Kecamatan Babahrot memiliki kedalaman muka airtanah sebesar 0,42 hingga 1,58 meter, sedangkan jenis akuifer tergolong kedalam jenis akuifer bebas dan akuifer tertekan dengan litologi terdiri dari pasir, pasir dan kerikil jenuh. Untuk jenis akuitar dilokasi penelitian berdasarkan data resistivitas diperoleh hasil yaitu lempung pasiran, lempung, dan kerikil sedang. Berdasarkan metode GOD yang telah dilakukan, menunjukkan hasil tingkat kerentanan airtanah di lokasi penelitian termasuk kedalam kategori rendah, tinggi, dan sangat tinggi. Dari hasil pengujian geokimia airtanah dilokasi penelitian menunjukkan nilai konsentrasi biochemical oxygen demand (BOD) pada 3 titik sampel airtanah di lokasi penelitian melewati batas ambang dengan batas maksimum sebesar 2 mg/l yaitu pada sumur S-01 sebesar 2,032 mg/l; sumur S-02 sebanyak 2,490 mg/l, dan sumur S-05 sebanyak 2,1951 mg/l.

Abstract

Based on geological conditions, the research location is in the Seurela Formation. The Seurela Formation has a lithology consisting of sublitoral calcareous sandstone and mudstone with a Pliocene age. Although the Seurela Formation has been extensively studied regarding its stratigraphy and sedimentology, information concerning sandstone provenance—specifically based on quantitative petrographic analysis and tectonic setting interpretation—remains limited. Consequently, the origin of the sedimentary material and its relationship to the region's tectonic evolution are not yet comprehensively understood. Provenance analysis was conducted on the sandstone using geological mapping and petrography methods. The geological mapping method was carried out by collecting data directly in the field through observations of rock lithology. Meanwhile, the petrography method was analyzed using JMicrovision to calculate the mineral composition in thin sections of the rock. This study was conducted to determine the geological conditions and provenance of the sandstone in the Seurela Formation at the research location. Based on the research that has been done, the results indicate that the Seurela Formation is found with alternating carbonate silt sandstone. Provenance analysis at the research location was conducted on four sandstone samples with codes OC52, OC57, OC25, and OC27. Provenance analysis was performed using a QFL diagram. Based on the origin analysis, the sandstone in the Seurela Formation indicates from a tectonic recycling orogen and an eroded arc environment.

Abstract

Seismic site characterization is needed for earthquake risk mitigation and also for geotechnical infrastructure design. Multichannel Analysis of Surface Waves (MASW) can be used for seismic site characterization. The method extracts shear-wave velocity (Vs) profiles from surface wave analysis that reveal geotechnical conditions and subsurface structures. This study aims to characterize the subsurface layers using the MASW method in Aceh Besar. Data acquisition was carried out along three measurement profiles, each 69 meters long and with a receiver spacing of 3 meters. Shear-wave velocities (Vs) of the subsurface soil and rock layers were estimated using dispersion curve analysis and 1D inversion. The surface wave spectral analysis produced a high-quality dispersion at the fundamental mode frequency of 20–30 Hz. The inversion process, validated by an excellent misfit curve, yields a seven-layer Vs model with RMS values mostly below 0.01. The 2D pseudo-section models based on 1D inversion results show a subsurface stratification consisting of a soft to medium overburden (Vs < 350 m/s) layer of 15 meters thick, followed by a transition zone of dense soil, and engineering bedrock (Vs > 750 m/s) found at a depth of 30 to 40 meters. In general, lateral variations were identified as undulating bedrock topography and local basin structures. Based on SNI 1726:2019, the site is classified as Medium Soil (SD) to Very Dense Soil (SC), with an estimated Vs value influenced by the thickness of the surface sediment. These results provide a valuable overview of subsurface conditions from site characterization and can serve as a basis for geotechnical planning in the study area.
