Abstract

Telah dilakukan investigasi akuifer air tanah di daerah Selaparang, Kota Mataram, Nusa Tenggara Barat dengan menggunakan metode geolistrik resistivitas konfigurasi Schlumberger. Tujuan dari penelitian ini adalah mengidentifikasi akuifer air tanah di daerah tersebut. Pengukuran data dilakukan di tiga titik yaitu SLPRG-1, SLPRG-2, dan SLPRG-3. Panjang lintasan SLPRG-1 adalah 225 meter sedangkan SLPRG-2 dan SLPRG-3 mencapai 150 meter dengan spasi 1 meter. Pengolahan data dilakukan dengan IPI2WIN untuk memperoleh gambaran distribusi resistivitas batuan secara 1D. Hasil interpretasi menunjukkan bahwa struktur batuan yang menyusun bawah permukaan di daerah penelitian terdiri atas lempung, pasir, batu pasir, batu gamping, dan kerikil. Dari tiga titik pengukuran, potensi akuifer air tanah tersusun atas pasir dan batupasir yang terletak pada rentang kedalaman 1,04 hingga 90,78 meter. Litologi pasir dan batu pasir tersebut merupakan jenis sedimen yang diprediksi cukup baik di daerah penelitian karena bersifat permeabel untuk menyimpan dan meloloskan air.

Abstract

The level of damage caused by an earthquake is related to the physical parameters obtained from Horizontal-to-Vertical Spectral Ratio (HVSR) analysis. The dominant frequency (f0) and wave velocity are the two HVSR parameters used. This research aims to determine the type of rock and the level of damage to buildings caused by the 2018 Lombok earthquake. We used secondary data from the 2011 Mataram City microtremor, which included 85 measurement points. We conducted frequency spectrum analysis using the HVSR method and shear wave velocity (vs) inversion modeling to gain a comprehensive understanding of Mataram City seismic properties. The Poisson ratio analysis results reveal that earthquake-prone sedimentary layers dominate Mataram City. The HVSR analysis revealed a negative correlation between the damage from the 2018 earthquake and the dominant frequency and shear wave velocity. The overlay results between the dominant frequency values, shear wave velocity, and the comparison of vp and vs with the damage level from the 2018 earthquake demonstrate this.

Abstract

Research on site vulnerability identification using the Refraction Microtremor (ReMi) method has been conducted in Sambelia District, East Lombok regency. The purpose of this study was to identify the vulnerability of the soil in the study area by determining the lithology of subsurface rocks. Measurement of Microtremor Refraction (ReMi) was carried out at 16 points spread over the study area. Data processing to obtain 1D shear wave velocity profile using McSEIS seisimager surface wave analysis wizard. Based on the research that has been done, four layers of rock are obtained, namely the first layer with a value of Vs 466-543 m/s in the form of clay at a depth of (0-6.0 m), the second layer with a value of Vs 429-668 m/s in the form of solid sand and gravel at a depth of (6.0-16.1 m), the third layer with a value of Vs 726-812 m/s in the form of breccia at a depth of (16.1 - 18.6 m), and the fourth layer with a value of Vs 905-1454 m/s identified as the Tuff is at a depth of (18.6 – 30.0 m). The conclusion of this study is that Belanting and Sugian villages have a high level of vulnerability because they are dominated by very dense soils and soft rocks (Type C) with constituent rocks, namely alluvial rocks (solid sand, gravel, clay, and silt) and Darakunci village has a low level of vulnerability composed of breccia and Tuff rocks.

Abstract

Community service in Narmada Village, West Lombok, aimed to improve the quality of science and technology literacy learning through a contextual and educational approach. These activities included teaching practices using simple teaching aids, training in developing locally-based Lesson Plans (RPPs), and digital image security education using the SCBIE encryption algorithm. Results showed significant improvements in students' understanding of science concepts and active participation, as well as teachers' skills in designing relevant RPPs. Furthermore, an understanding of the effectiveness of the SCBIE algorithm was gained, with the use of a single key yielding higher e-RMS values, indicating a stronger encryption level. A comparison of the performance of algorithms A and B was also discussed during the training, emphasizing the importance of balancing speed, accuracy, and memory efficiency in implementing image cryptography. This activity significantly contributed to improving educational capacity and digital literacy at the village level.

Abstract

The Dasan Geres Tengah neighborhood of Dasan Geres Village, Gerung District, West Lombok Regency, has a standard economic condition because the community has an average livelihood as Farmers and Traders. The role in contributing to creating new skills to be developed in the village by young men and women and housewives in particular is not very exposed by the people in the area. In this regard, the role of youth groups and housewives in the Dasan Geres Tengah neighborhood is expected to be able to create initiatives in making simple skills activities, a small example of which is the use of land in developing food houses that can be used continuously, so that it can be useful in helping to facilitate the basic daily needs of housewives in particular.

Abstract

Indonesia has a high level of geological disaster threat due to its location at the meeting point of three tectonic plates, making coastal areas, such as Lombok Island, very vulnerable to earthquakes and tsunamis. Although Lombok has a history of earthquakes (2018) and tsunamis (1977), initial observations in Torok Aik Belek Hamlet, South Lombok, show that community awareness and preparedness for disaster mitigation are still low, exacerbated by unverified information on social media and the perception of underestimating potential hazards. This study aims to conduct participatory earthquake and tsunami risk mapping in Torok Aik Belek Hamlet and develop community-based mitigation strategies. The implementation methods include initial assessment, coordination with BMKG, presentation of materials, interactive counseling, and community empowerment as a disaster preparedness team. The results of the activities show clear identification of disaster-prone locations (for example, residential areas near the coast and concrete buildings) and vulnerable groups. Utilization of local potential, such as hills as evacuation routes and disaster-resilient village status, is the basis for developing disaster mitigation strategies. The formation of a local community in Torok Aik Belek Hamlet involving residents and members of the Disaster Resilient Village is a crucial step. It is hoped that this effort can significantly increase the preparedness of the Torok Aik Belek Hamlet community and contribute to an adaptive and sustainable community-based mitigation development model.
