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

Perubahan garis pantai merupakan fenomena dinamis yang dipengaruhi oleh interaksi faktor oseanografi dan aktivitas manusia, sehingga perlu dipantau secara berkelanjutan. Tujuan penelitian ini adalah untuk menganalisis dinamika perubahan garis pantai di Pantai Lampia, Kabupaten Luwu Timur, dengan memanfaatkan citra Google Earth multitemporal. Data yang digunakan meliputi citra tahun 2016, 2019, dan 2023 yang didigitasi secara on-screen, kemudian dianalisis menggunakan pendekatan komparatif per transek. Hasil penelitian menunjukkan bahwa periode 2016–2019 ditandai dengan abrasi signifikan pada titik sampel TS1 (−14,82 m) dan TS6 (−14,46 m), sementara beberapa segmen lain mengalami akresi hingga +7,35 m. Pada periode 2019–2023, pola perubahan cenderung lebih moderat dengan amplitudo antara −5,02 m hingga +6,90 m. Zona abrasi yang sebelumnya berada pada bagian timur (TS1, TS6, TS7) bergeser ke segmen barat–tengah (TS9–TS12), sedangkan area yang sebelumnya mengalami abrasi justru mengalami akresi. Kesimpulan dari penelitian ini adalah garis pantai Lampia bersifat sangat dinamis dengan adanya pergeseran zona abrasi–akresi antarperiode. Pola tersebut menunjukkan adanya redistribusi sedimen yang dipengaruhi kombinasi faktor gelombang, arus sejajar pantai, pasang surut, serta aktivitas antropogenik. Pemanfaatan citra Google Earth terbukti efektif sebagai alternatif pemantauan garis pantai yang murah, praktis, dan aplikatif untuk mendukung pengelolaan wilayah pesisir.

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.
