Abstract

Groundwater is water that sourced from rainwater, river water and others which seeps into the ground and accumulates in a layer called an aquifer. Estimation of the distribution and identification of aquifer geometry is carried out to assist the people of Cot Madhi Village in an effort to design the depth of drilling to obtain water that will be used for their basic and supporting needs. In this measurement, the 1D resistivity geoelectric method is used to determine the resistivity value changes of the rock layer which serves to identify the type of aquifer and the depth of the aquifer for efficient drilling of well activities. The measurement uses Supersting instruments with Wenner-Schlumberger cable configuration. The results showed subsurface resistivity values in the measurement area between 3.4 - 112.1 m. The penetration depth in this measurement is up to 165 meters deep. The resistivity model profile indicates a very economical water layer (aquifer) with a resistivity of 27.3 m located at a depth of 54-84 meters with a thickness of 30 meters. This research found a potential aquifer layer as a source of clean water.

Abstract

The potential for groundwater is very large and widely distributed in Aceh Besar District as indicated by the Groundwater Basin map. This potential is supported by the presence of sedimentary deposits consisting of materials such as gravel, sand and clay. This research was conducted to identify the type of aquifer and calculate the amount of groundwater discharge in the district of Aceh Besar. The discharge calculation is carried out using Darcy's Law where this equation can be used to describe the ability of the aquifer to flow through the rock. This study also compares the results of calculating the water discharge using Darcy's Law with the real Pumping Test data. The results showed that the coastal area of Aceh Besar was dominated by confined aquifers with average depth of 40-120 m and thickness of 3-30 m. The results of calculating the water discharge (flux) in the study area were obtained around 3414.61 m/day or equivalent to 39.51 liters/second. The results of comparison with the real Pumping Tes data in segment 2 found that the results of calculating discharge using Darcy's Law were 23.93 liters/second while the results of real Pumping Test were 25.5 liters/second so that the error value found is 6.1%, and in segment 3 the results of calculating discharge using Darcy's Law is 21.88 liters/second while the results of the real Pumping Test are 21 liters/second so that an error value of 4.2%.. From the results of these two comparisons, it can be seen that the calculation of water discharge using Darcy's Law is comparable and has significant results with the results obtained from the real Pumping Test, so that the calculation of water discharge using Darcy's Law can be used for a reference in the groundwater exploitation.

Abstract

Observations to determine subsidence potential were conducted in East Aceh, based on sediment characterization using logging data. The study encompassed 9 measurement sites representing 9 villages from 9 sub-districts. The data used obtained from the Aceh Energy and Mineral Resources Service (ESDM). This data is processed to obtain the resistivity value of the subsurface sediment layer. The measurement results were then depicted in 1D profile illustrating the cross-section of subsurface lithology for each measurement point. Subsequently, several measurement points were correlated to generate a 2D bottom image representing two regions, referred to as cross-section A-A' and cross-section B-B'. The correlation outcomes revealed that cross-sectional area A-A', spanning approximately ±50 km from east to west through Cot Geulumpang Village, Java Village, Kuala Lawah Village, Bukit Seroja Village, and Rantau Panjang Village, shows a shallow surface layer consisting mostly of sand and sandy clay soil. The sand layer in this area exhibited a medium to fine size with a configuration of round-shaped particles containing quartz and shell minerals, forming a soft sediment layer. The structure and type of sediment in this area indicate the potential for land subsidence.

Abstract

This study identifies the sliding plane along the Seulawah Road (km 80-81), Muara Tiga, Pidie Regency, where a massive landslide occurred in 2023. Using the Multichannel Analysis Surface Waves (MASW) method, this research integrates shear wave velocity (Vs) data with N-SPT values and soil-bearing capacity to analyze subsurface characteristics. The study aims to characterize the sliding plane and associated weak zones by combining geophysical and geotechnical approaches. The interpretation reveals the existence of a sliding mass layer consisting of sandy gravel material at a depth of 1-3 meters with a Vs value in the range of 60-150 m/s. Underneath that, the sliding plane is found, which is interpreted as a stiff clay layer with the Vs value in the range of 155-450 m/s at a depth of 6-10 meters. The soil bearing capacity also aligned with these findings with the 20-80 kN/m2 value in the very loose sandy gravel layer. The soil-bearing capacity of the sliding plane, the clay layer, is 250-311 kN/m2. Those findings provide valuable insights into landslide characteristics and highlight the dynamic instability of the sliding plane. Moreover, this study contributes to assessing critical parameters for future reconstruction and road maintenance, offering an essential reference for landslide-prone regions.
