Abstract

Lam Apeng is a village with a majority of people living as farmers, which causes the need of water for agriculture is increasing. The water demand in this area continues to increase as the population increases, for various purposes. The objective of this study is to determine the distribution of the groundwater layer using the electrical resistivity method and to determine groundwater potential using hydraulic parameters. This research is conducted using 2 measurement line with a length of each line is 112 meters and distances of each electrode is 2 meters. The data invert using Res2Dinv software to obtain 2D subsurface lithology subsurface. At line 1, the aquifer (sand) layer is located in the second layer with a rock resistivity value of 12 Ωm - 18.6 Ωm at a depth of 8 m - 18 m. At line 2, the aquifer (sand) layer is also located in the second layer with a resistivity value of 4.6 Ωm - 18 Ωm at a depth of 5 m – 12 m. Based on the interpretation of the two measurement lines, it can be concluded that the type of aquifer in the research site is a semi unconfined aquifer. In this study, hydraulic parameters (hydraulic conductivity, longitudinal conductance, transverse resistance, and transmissivity) was calculated based on the resistivity value and the thickness of the aquifer layer. The average resistivity of the aquifer layer used is 15.3 Ωm and 11.3 Ωm, respectively for line 1 and line 2, indicating that the aquifer was moderately corrosive. Longitudinal conductance values are 0.65 Ω-1 and 0.62 Ω-1 which indicated moderate protective capacity. The transmissivity values are 6.78 m2/dayand 4.77 m2/day, which indicates that the designation in this area is low and the groundwater potential is local or only for personal consumption.

Abstract

Most of the Singkil communities live along the river banks. Their long-term experience has generated some local wisdom in flood hazard mitigation and adaptation. To revitalize the values of the local wisdom, we have researched Cingkam Village, Aceh Singkil District, Aceh Province. A descriptive exploratory method was used in this study. Field data were collected based on field observations, interviews with local communities, and in-depth interviews with community leaders and local government regarding knowledge, experience, implementation, and possibility of developing the local wisdom. The results showed that the Singkil community practice local wisdom on structural mitigation and adaptation in flood hazards. They constructed floating buildings, namely sapao metungkhang, lampung, and bagan, made of logs drifting along the river. The buildings are practically effective, so that daily household and communal activities can still be carried out both in normal conditions and during flooding. However, they tend to disappear due to several factors including shortages of raw materials, progress inland transportation development, relocation of community far from rivers, and dimmed water transportation routes. Although the practices are starting to be abandoned, they still have the potential to be preserved and developed for both flood risk reduction and tourism destinations.

Abstract

Estimation of the subsurface geological structures in oil and gas prospect area of West Aceh has been done by utilizing gravity field anomaly of satellite gravity data. This research aim to analyze satellite gravity data in order to get geological features which is include deep and shallow structure or fault around oil and gas prospect area in West Aceh. The satellite gravity data is originally provided as Free Air Anomaly and should be corrected to get Complete Bouguer Anomaly (CBA). Furthermore, CBA was transformed into a horizontal plane and corrected from regional anomalous effects to obtain residual anomaly, horizontal and vertical derivative. From CBA, the gravity anomaly show good correlation with geological boundaries on different rock formation and the anomaly is decrease from NE-SW. Residual anomaly also gives same information with CBA but this anomaly focus on shallow structure. Furthermore, horizontal derivative and vertical derivative also show good correlation with geological structure or fault but in some areas the anomaly related with deep structure cannot be seen on the surface or geological map. Despite the result cannot correlate directly with oil and gas prospect area, satellite gravity can be used to identify gravity anomaly and also fault that related with hydrocarbon anomaly area

Abstract

The need for clean water around the world is related to the increasing population, especially in Teupin Batee Village, Aceh Besar District. In addition to surface water, groundwater is one of the potentials that can be utilized by the community, particularly for household needs. The purpose of this study is to identify the aquifer layer using the geoelectric method. One of the geophysical methods that can be used to map groundwater potential is the geoelectrical method based on the resistivity value of subsurface rocks. This study uses the Wenner-Schlumberger array because it can map subsurface structures both vertically and horizontally. From the results of the study, it was found that there are four different layers in this research area including, the top soil layer, hard rock, tuffaceous sand and sand layer as aquifer layer. The top soil layer is mixed with tuff, sand and volcanic breccia to a depth of 8 m with a resistivity value of 5-25 ?m. The Hard rock layer is at a depth of 8 m – 30 m with a resistivity value of 45-220 ?m. The tuffaceous sand layer has a resistivity value ranging from 25-55 ?m. While the sand layer or aquifer is at a depth of 10 m – 60 m with a resistivity value of <10 ?m which is separated by a layer of tuffaceous sand between the two aquifer layers.

Abstract

This community service program aims to map zones that have the potential to have aquifer layers as sources of clean water. The activity was carried out in Lam Apeng Village, Aceh Province. Clean water is a basic human need in life and in this village getting sufficient water sources or aquifers is still a challenge. By using the geophysical method, namely the geoelectric method, which is one of the geophysical methods widely used in Indonesia as an environmentally friendly and inexpensive method, we can identify underground layers that contain water based on the resistivity values ​​obtained from the measurements. Community involvement in data collection can also help with general mapping in the research area. The survey results show a potential aquifer zone at a depth of 6 to 18 meters. These findings can support future well drilling efforts. This activity shows the importance of combining science and local participation to solve everyday problems in rural areas.

Abstract

Earth science is one of the science fields competed in the National Science Olympiad (OSN) for Senior High Schools (SMA). However, not all schools provide earth science as a separate subject, so students often face difficulties in learning complex and multidisciplinary materials. This community service activity was carried out to train students to face the selection of OSN at the district/city level through structured coaching and field practicums in strengthening student competency in the field of earth science. The method of implementing the activity includes 3 stages, namely the preparation and coordination stage, implementation of activities, evaluation, and follow-up. The results of the activity showed a significant increase in student competency in the field of earth science, on average posttest scores in the range (65-80) compared to the pretest (25-40) on each topic of material, which was also reinforced by the results of the Quizizz application-based practice questions. In the school-level selection, five students were successfully selected to continue to the district-level OSN, and one of them achieved an achievement at that level. Overall, this community service activity has not only succeeded in improving students' academic readiness to face OSN but also strengthened the culture of scientific learning, observation skills, and collaboration between universities and schools to produce a superior young generation in the field of earth sciences.

Abstract

This study aims to analyse the subsurface lithology in the landslide-prone area at KM-25 West Cross Road using a 2-dimensional resistivity method with a dipole-dipole configuration on two measurement tracks. The inversion results reveal significant lithological heterogeneity, with a low resistivity zone (<50 Ωm) at a depth of 5-20 metres, interpreted as a water-saturated clay layer or weathered material. The physical properties of this layer contribute to increased pore pressure, potentially forming a slip plane. The transition zone between the saturated clay layer and hard rock with high resistivity (>100 Ωm) is identified as a geomechanically weak zone prone to ground movement, primarily when saturation occurs due to heavy rainfall. The resistivity cross-section of the second pass shows similar features, with a thicker and wider zone of very low resistivity (<30 Ωm), indicating the presence of soft clays or unconsolidated fill. These results emphasise the importance of early detection of subsurface resistivity contrasts as indicators of landslide potential. This research provides an essential contribution to disaster mitigation efforts and can serve as a basis for spatial planning and infrastructure design to enhance resilience against geological hazards.

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

Institute of Technology Sumatra (ITERA), as an educational institution located in the Lampung Province, continues to strive for the development of educational support facilities such as lecture halls and laboratories. The ITERA campus is in an area with potential natural disaster threats like earthquakes, due to the tectonic activity of the Great Sumatran Fault and the subduction of the Indo-Australian plate and the Eurasian plate. To mitigate the risk of disasters on the ITERA campus, infrastructure development planning requires a seismic microzonation study. This research was conducted to determine the dominant frequency (f0​), amplification factor (A0​), and seismic vulnerability index (Kg​) using the Horizontal to Vertical Spectral Ratio (HVSR) method. The results show that the dominant frequency (f0​) values range from 1 to 4 Hz, the amplification factor (A0) from 1.8 to 4, and the seismic vulnerability index (Kg​) from 2 to 15. The seismic microzonation map of the ITERA campus, the northern part of the area is categorized as having a medium to high seismic vulnerability index (Kg​), with a low dominant frequency (f0​) and a high amplification factor (A0​).
