Abstract

Landslide disasters frequently occur in the Nupabomba area due to its steep slopes and its role as a primary access road for the local community. This study aims to analyze slope stability using the Rock Mass Rating (RMR) and Slope Mass Rating (SMR) methods to assess the potential for landslides. The research was conducted at coordinates (Universal Transverse Mercator) UTM 829117.90 – 831853.89 mE and 9920980.82 – 9920308.34 mS. Data collection involved field measurements using the scanline method, focusing on discontinuities, lithology, and rock strength. The results indicate that at Station 01, the slope consists of slate rock with an RQD value of 70% and UCS of 23 MPa. The calculated RMR value is 58, placing it into Class III (fair rock), with an SMR value of 55.4, indicating partially stable conditions. Meanwhile, at Station 02, the slope consists of phyllite rock with an RQD value of 70% and UCS of 52 MPa. The RMR value is 62, classifying it as Class II (good rock), and the SMR value is 61.6, indicating a stable condition. These findings provide crucial insights into the geotechnical characteristics of the area, which are essential for landslide risk mitigation and infrastructure planning. The study highlights the need for continuous monitoring and possible reinforcement strategies, particularly in areas categorized as partially stable. Further research incorporating geotechnical modeling and additional stability analysis is recommended to enhance slope stability predictions and inform mitigation strategies.

Abstract

Indonesia is highly vulnerable to geological disasters, especially earthquakes and secondary hazards, due to its location at tectonic plate boundaries and active faults. However, junior high school students’ understanding of earth science and disaster mitigation remains low. This community service project aimed to enhance disaster literacy through interactive socialization at SMP Negeri 19 Palu (high-risk earthquake area). Methods included lectures, group discussions, educational videos, and disaster response simulations, focusing on earth science fundamentals (earth structure, rocks, geological processes) and mitigation measures for earthquakes, tsunamis, and liquefaction. Participants were Grade VIII students, selected for their potential as agents of change. Results demonstrated increased disaster awareness, mitigation knowledge, and interest in earth science. The activity fostered early disaster preparedness culture and established university-school partnerships, supporting education-based disaster risk reduction programs. Positive feedback from students and the school confirmed the effectiveness of the communicative approach.

Abstract

Beberapa daerah di Propinsi Sulawesi Tengah masih belum terakses oleh layanan PDAM, termasuk Desa Sarombaya Kecamatan Banawa Selatan di Kabupaten Donggala. Memanfaatkan air sungai menjadi pilihan untuk memungkinkan masyarakat mendapatkan sumber air bersih yang layak minum. Permasalahan khalayak sasaran PKM adalah rendahnya kualitas fisik dan kimia sumber air sungai Bambarimi untuk kebutuhan air bersih. Hal ini disebabkan karena belum teraksesnya lokasi ini oleh pelayanan air minum (PDAM) Kabupaten Donggala dan mengandalkan sumur gali juga kualitasnya tidak memenuhi syarat. Kendala yang dihadapi penduduk setempat, jika hujan maka air sungai juga jadi semakin keruh dan sulit untuk dijangkau karena banjir. Kondisi ini memerlukan adanya metode yang dapat mengatasi permasalahan air bersih bagi masyarakat setempat. Program Kemitraan Masyarakat (PKM) ini bertujuan untuk menerapkan model pengolahan air sungai menjadi air bersih dengan metode saringan pasir lambat (SPL). Adapun mitra dalam Program Kemitraan Masyarakat ini adalah Dasawisma Mawar, dengan 30 anggota Dasawisma. Berdasarkan hasil kegiatan berupa sosialisasi model SPL yang dilakukan, maka hasil dari pelaksanaan program PKM ini adalah: 1). Peningkatan pengetahuan, wawasan dan keterampilan kelompok mitra tentang model pengolahan air sungai menjadi air bersih, sejumlah 87%, 2).

Abstract

This study aims to analyze slope stability in Walenrang District, Luwu Regency, South Sulawesi, using the Rock Mass Rating (RMR) method. The research area lies along the Walenrang–Toraja main route, which is composed of volcanic and sedimentary rocks affected by an intensive joint system. Field investigations were conducted using the scanline method to obtain geotechnical parameters such as unconfined compressive strength (UCS), Rock Quality Designation (RQD), discontinuity spacing and condition, and groundwater condition. Based on Schmidt Hammer test results, the rock’s compressive strength was 64 MPa with an RQD value of 97%, indicating excellent rock quality. The weighting of six key parameters produced an RMR value of 69, classifying the rock mass as Class II (good rock). This finding indicates that the slopes at the research location are still in good condition.

Abstract

This research was conducted in the Mananggu area and its surroundings, Mananggu District, Boalemo Regency, Gorontalo Province. The study aims to map the geological conditions and identify the characteristics of geomorphology and geological structures developed in the area. The methods employed included surface geological mapping for field data collection, followed by laboratory analyses. Geomorphologically, the research area is divided into two units: the Volcanic Hills Unit and the Structural Hills Unit. The stratigraphy consists of the Eocene-Oligocene Porphyritic Andesite Unit (Tinombo Formation) and the Pliocene Granite Unit (Bumbulan Granodiorite Formation) acting as an intrusive body. The geological structures are controlled by a transtensional regime resulting from compression, manifested as NW-SE shear joints, right normal slip faults, and normal right slip faults. The landscape evolution is strongly influenced by the interplay between the resistance of the igneous lithologies and the active tectonic deformation that shapes the drainage patterns and slope configurations.
