Abstract

North Central Timor Regency has a high level of landslide vulnerability, while students’ understanding of disaster mitigation remains low. This community service program aims to enhance the science and technology literacy of students at SD Negeri Lulu through learning activities using an Internet of Things (IoT)-based landslide miniature as an educational medium. The miniature is designed to simulate landslide processes with IoT sensors that monitor soil moisture, allowing students to directly observe the relationship between environmental conditions and landslide potential. Through this activity, science and technology learning becomes more contextual, interactive, and engaging for elementary school students. The program also supports Sustainable Development Goals (SDGs) 4 (Quality Education), 11 (Sustainable Cities and Communities), and 13 (Climate Action). The integration of technology in science education has proven effective in improving students’ understanding of abstract geophysical and environmental concepts. Through experiments using the IoT-based miniature, students not only gain theoretical knowledge but also understand the practical application of technology in analyzing natural phenomena. This activity is expected to serve as a model for science and technology learning based on disaster mitigation in landslide-prone areas.

Abstract

Telah dilakukan penelitian dengan metode geomagnet untuk mengetahui struktur batuan bawah permukaan sekitar Pantai Kolbano, Desa Kolbano, Kabupaten Timor Tengah Selatan. Daerah penelitian memiliki luas 1000 m2 dengan 99 titik ukur. Proses akusisi data dengan sistem looping menggunakan alat Proton Prosession Magnetometer (PPM) tipe GSM-19T. Data yang diperoleh di lapangan berupa nilai medan magnet total. Penentuan posisi titik ukur menggunakan Global Positioning Sistem (GPS). Pengolahan data diawali dengan koreksi variasi harian dan koreksi IGRF untuk mendapatkan anomali magnetik. Reduksi kontinuasi ke atas pada ketinggian 10 meter bertujuan untuk memisahkan anomali lokal dan anomali regional. Pemodelan dengan metode forward modeling menggunakan software Mag2DC for windows. Hasil interpretasi kualitatif diperoleh tiga pola anomali, yaitu anomali tinggi dengan rentang nilai 120 nT - 260 nT, anomali sedang dengan rentang nilai 100 nT - 110 nT, dan anomali rendah dengan rentang nilai 40 nT - 90 nT. Interpretasi kuantitatif menunjukan bahwa di lokasi terdapat beberapa jenis batuan, seperti batu pasir dengan suseptibilitas 1 x 10-4, 3,33 x 10-4, dan 1,657 x 10-3; batu lempung dengan suseptibilitas 5,56 x 10-4, 6,71 x 10-4, 8,57 x 10-4, 9,86 x 10-4, 1,012 x 10-3, dan 1,32 x 10-3; batu gamping dengan suseptibilitas 2,07 x 10-4, dan 2,76 x 10-4; batuan metemorf jenis slate dengan suseptibilitas 2,225 x 10-3, 1,257 x 10-2, 1,314 x 10-2, dan 1,477 x 10-2. Batuan-batuan berwarna merupakan jenis batu pasir dan batu lempung yang tergolong dalam formasi aluvium.
