Abstract

Likuifaksi merupakan fenomena hilangnya kekuatan lapisan tanah akibat getaran gempa. Banda Aceh termasuk ke dalam zona rawan likuifaksi berdasarkan identifikasi penurunan tanah lehih dari 20 cm. Agar perencanaan dan langkah mitigasi tepat dan efektif maka perlu pemahaman yang baik oleh masyarakat sekitar terhadap ancaman dan dampak yang ditimbulkan oleh bencana likuifaksi. Tujuan dilakukannya pengabdian ini ialah untuk mengetahui tingkat pemahaman siswa SMA Laboratorium USK terhadap bencana likuifaksi. Metode pengabdian ini dilakukan dengan melakukan studi literatur terkait potensi dan bencana likuifaksi di Kota Banda Aceh, merumuskan pertanyaan permasalahan terkait pemahaman siswa terhadap bencana likuifaksi, melakukan pengumpulan data melalui survei online dengan metode wawancara kepada informan. Berdasarkan survei online yang telah dilakukan terlihat dari ≥40 responden (≥80%) yang mengetahui jenis bencana yang disebabkan oleh adanya likuifaksi dan hampir 40 responden (≈80%) yang tidak mengetahui apa itu istilah likuifkasi. Disisi lain, tingkat pemahaman siswa terkait bencana likuifkasi masih kurang karena sebagian besar siswa telah memahami defenisi dan contoh manifestasi likuifaksi dibuktikan dengan presentase responden yaitu rata-rata >50% atau sekitar >25 orang. Namun mereka kurang memahami faktor-faktor yang menyebabkan terjadi likuifaksi dibuktikan dengan persentase responden yang mampu menjawab soalan dan uraian terkait penyebab likuifaksi yaitu rata-rata <50% atau <25 orang

Abstract

Earthquakes, a disaster that often occurs in Indonesia, are caused by the movement of tectonic plates. Indonesia is a region located at the meeting of three active plates, namely, Indo-Australian, Eurasian, and Pacific, which gives Indonesia a high level of vulnerability to earthquake disasters. Banda Aceh is one of Indonesia's regions with a high vulnerability to earthquake disasters, so awareness of disaster mitigation is needed early on. Children have a higher level of disaster vulnerability than adults because they can still not control and prepare themselves for disasters. One effort that can be made to increase children's knowledge about disaster mitigation is to conduct disaster outreach. The outreach aims to increase children's understanding of the dangers of earthquakes, evacuation steps, and first aid that must be carried out to reduce the impact of disasters. Socialization includes interactive presentations, discussions, and evaluations to measure students' understanding of disaster material. The sample for this socialization was 25 grade IV students and 31 grade VI elementary school students. Data collection will use tests in the form of questions about earthquakes to measure the results of students' knowledge of disaster mitigation and compare their understanding of class IV and class VI students. The results of the socialization show that the level of understanding of class VI students is higher in understanding the material provided; around 90% of class VI students and 82% of class IV students understand the material that has been provided; this number has increased from before the disaster socialization was carried out.

Abstract

The tsunami that struck Aceh in 2004 caused significant damage to agricultural land, altering soil properties and affecting productivity. Mon Ikeun Village was one of the most affected areas in the Lhoknga Subdistrict of Aceh Besar Regency. As an agricultural area vulnerable to soil salinization, it faced reduced soil quality, fertility, and nutrient availability risks, which could significantly decrease crop productivity. Therefore, assessing the current condition of agricultural soils is essential to determine whether recovery has occurred or if contamination persists. This research investigates the condition of agricultural soils two decades after the tsunami by analyzing resistivity and soil pH measurements. The resistivity data were collected using a SuperSting R8 device with a Wenner configuration and subsequently processed with IPI2WIN. The pH was determined with a Hanna HI 991001 pH Meter. The results reveal that the affected soils present resistivity values between 9.06 Ωm and 131 Ωm, indicating compositions of sandy clay and sand layers. Soil pH ranges from 4.9 to 6.2, indicating slightly acidic to near-neutral conditions, suitable for agriculture. These results indicate a substantial recovery in soil conditions, especially when compared to a control site in a non-affected area with similar land characteristics. This reinforces the interpretation that the tsunami’s impact has diminished over time. This recovery is likely influenced by natural processes such as leaching of contaminants through rainfall. This integrated approach effectively evaluates long-term changes in agricultural soil affected by the tsunami. However, to obtain a clearer understanding of the soil recovery process, future studies could include additional measurements such as soil nutrient analysis, electrical conductivity, or salinity levels to offer more detailed insights.

Abstract

Meulaboh, in West Aceh Regency, is one of the areas with potential for landslides. The goal of this research is to identify soil conditions that could lead to landslides based on resistivity data, as well as to analyze the distribution of landslide potential using geospatial data. This research provides benefits to various stakeholders, including the government. It contributes to improved disaster mitigation planning, reduced risk of losses, and the selection of appropriate materials to construct more disaster-resilient infrastructure. The research methods used are 2D resistivity and geospatial methods with weighted overlay analysis. Based on the processing results of 2D resistivity data from profiles 1 and 2, the study area is characterized by silt, sand, and sandstone. The resistivity values of the material in profile 1, identified for silt, range between 1 and 119 Ω.m at depths of 2-59 meters. For sand, the resistivity values range between 120-225 Ω.m at 2-61 meters depths. Sandstone has resistivity values that range between 226-500 Ω.m at depths of 3-62 meters. The resistivity values of the material in profile 2, identified for silt, range between 1-119 Ω.m at depths of 1.5-60 meters. For sand, the resistivity values range between 120-225 Ω.m at 9-59 meters depths. Sandstone has resistivity values that range between 226-500 Ω.m at depths of 15-39.4 meters. The presence of silt (1-119 Ω.m) increases the potential for landslides due to its cohesive nature. Based on the weighted overlay analysis processing results, the study area has a moderate potential for landslides. The study area has characteristics such as a gentle to steep slope (8-45%), a high rainfall rate (2500-3000 mm/yr), a lithology consisting of rocks from the Tutut Formation, including silt, sand, and a small amount of conglomerate, and land that is used for plantations and rice fields.

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

This study characterises the subsurface soil properties in the western sector of Syiah Kuala University, specifically the Kopelma Darussalam area, using Vertical Electrical Sounding (VES) with a Schlumberger configuration. Nine measurement points were deployed to obtain resistivity profiles supporting infrastructure development planning. The results indicate that the surface layer (0–15 m) exhibits high resistivity (12.0–270.2 Ωm), suggesting dry sandy material with high permeability and sufficient bearing capacity. Below 15–30 m, resistivity decreases (1.9–26.5 Ωm), indicating a water-saturated layer potentially functioning as an aquifer, which has implications for soil stability. The deepest layers (>30 m) show low resistivity (<5 Ωm), reflecting low-permeability materials less suitable for heavy construction, though some high-resistivity anomalies suggest dense sandstone formations suitable for foundations. These findings provide preliminary geotechnical zoning insights, aiding developers in selecting appropriate foundation locations, improving construction safety, and ensuring long-term infrastructure stability at University Syiah Kuala.
