Abstract

Disaster resilience is being implemented by transferring knowledge about potential disasters in the surrounding areas, mitigation strategies, and information sources to teachers and students in schools, aimed at enhancing community capacity to support Kurikulum Merdeka Belajar. The Community Service Program (CSP) team presented information about potential disasters in the Province of Jambi, illustrated maps of potential disaster areas, and demonstrated the use of InaRisk. Evaluation was conducted through surveys after the activity to assess the level of understanding among teachers and students regarding disasters and participant attendance surveys were also conducted. The CSP activities achieved an average attendance rate of 96.15% of registered participants. The results showed that participants' knowledge regarding potential disasters in Jambi City and Province was considered good after participating in this activity, with an average score of 4,53. This reflects the values of Pancasila, which is a goal of the Kurikulum Merdeka Belajar.

Abstract

Kabupaten Kerinci, dengan keberadaan Gunung Api aktif, rentan terhadap gempa bumi. Meskipun demikian, kawasan lereng bukit, terutama di Kayu Aro Barat, masih dihuni oleh banyak penduduk. Penelitian ini bertujuan untuk mengidentifikasi potensi kerentanan tanah di wilayah tersebut menggunakan metode mikrotremor. Hasil penelitian menunjukkan adanya variasi kerentanan tanah yang signifikan. Bagian barat laut memiliki kerentanan tanah yang lebih rendah (0,40-0,85), sedangkan bagian tenggara memiliki kerentanan yang lebih tinggi (2,19-2,64). Nilai Peak Ground Acceleration (PGA) maksimum tercatat di bagian tenggara dengan rentang 251-1729 mgal. Temuan ini mengindikasikan bahwa wilayah tenggara Kayu Aro Barat memiliki potensi risiko gempa bumi yang lebih tinggi dibandingkan wilayah lainnya. Meskipun nilai PGA masih berada dalam kategori aman, perlu diingat bahwa aktivitas seismik dapat memicu pergerakan tanah dan longsor, terutama di daerah dengan topografi curam dan kondisi tanah yang labil seperti di Kayu Aro Barat. Oleh karena itu, diperlukan kajian lebih lanjut dan upaya mitigasi risiko untuk melindungi keselamatan masyarakat.

Abstract

Jambi Luar Kota Subdistrict is located in a regional geology which is dominated by sedimentary layers and has the highest population density in Muaro Jambi Regency. The population that continues to increase has resulted in regional development in the form of infrastructure development, shops, roads, housing and high-rise buildings increasing very rapidly. In this development planning, information is needed regarding land conditions and regional stability conditions against the threat of soil movement by identifying the dynamic characteristics of the soil layer which includes the value of the seismic vulnerability index (Kg). The value of Kg was obtained by calculating the values ​​of fo and Ao from the results of microtremor data processing as many as 61 measurement points using the HVSR method. The fo values ​​obtained ranged from 0.31 to 6.08 Hz and the Ao values ​​ranged from 0.99 to 2.89. The Kg values ​​obtained ranged from 0.16 to 16.62 with a relatively high distribution of Kg values ​​in Sembubuk Village, Rengas Bandung, Kedemangan, Sarang Burung, Senaung, Penyengat Olak, Sungai Duren, Muaro Pijoan, Mendalo Darat, Mendalo Indah, Mendalo Laut, Muaro Pijoan, and Pematang Jering which show these areas are more susceptible to damage if there is ground movement. Key words : Microtremor, dominant frequency, amplification, seismic susceptibility index,HVSR

Abstract

The urgency of introducing disaster-based digital technology to elementary school students is increasing along with the rising frequency and intensity of natural disasters in Indonesia, particularly in Kerinci Regency. The lack of students' understanding about disaster risks and their mitigation could hinder the achievement of disaster resilience at the community level. The activity was conducted at SDN 48/III Sungai Jambu, Kerinci Regency, involving 20 students. The method used was technology-based learning with a participatory approach, engaging students in discussions, simulations, and the use of the application to understand disaster risks in their surrounding environment. Evaluation was carried out using a survey to assess students' satisfaction with the activity and changes in their understanding of disaster-related topics. Survey results showed that most students were satisfied with the activity and found it beneficial in improving their knowledge of disaster mitigation. Additionally, students demonstrated a better understanding of mitigation measures after participating in the activity. The use of digital technology in disaster education proved to be effective in building awareness and disaster preparedness among students. This activity can serve as a model for enhancing disaster education in other schools, especially in disaster-prone areas.

Abstract

This study investigates the geothermal manifestation in Sungai Medang, located within a volcanic arc depression zone of the Sungai Penuh Basin, formed by right-lateral movement along the segmented Siulak Fault. The exploration approach combined electrical resistivity and gravity methods to delineate subsurface features associated with hydrothermal activity. The electrical resistivity survey employed a dipole–dipole configuration with 25-meter spacing over a 400-meter line and the complementary gravity data from the Topex/Poseidon satellite altimetry were processed into Simple Bouguer Anomaly (SBA) maps. Resistivity survey revealed low-resistivity zones (11.6–99.1 Ωm), interpreted as hydrothermal fluid pathways and altered volcanic formations aligned with known fault traces, particularly the Siulak Fault segment. The gravity data indicated NW–SE trending density contrasts. Spectral analysis identified residual anomalies (~1.5 km depth) consistent with shallow sedimentary infill and structural depressions, while deeper regional anomalies (~38.7 km) reflected basement variations. The spatial correlation of resistivity lows, gravity lows, and surface manifestations suggests active geothermal upflow along structurally controlled zones. This study highlights the importance of integrating geophysical datasets for geothermal resource evaluation and offers a methodological framework applicable to similar underexplored regions in Indonesia and beyond.

Abstract

Informasi akan kandungan tanah penting diketahui sebagai dasar pengolahan pertanian. Pada Kabupaten batang Hari kecamatan pemayung Provinsi Jambi terdapat dua jenis tanah yang sering dimanfaatkan sebagai lahan pertanian yaitu tanah Ultisol dan Inseptisol. Dalam pemanfaatan sebagai lahan pertanian terhadap kedua jenis tanah tersebut umumnya pelaku pertanian melakukan penanaman langsung sehingga sering kali mendapatkan hasil yang kurang optimal akibat ketidaksesuaian jenis tanaman dan pupuk yang digunakan, untuk itu pada penelitian ini dilakukan karakterisasi terhadap tanah tersebut. Sampel tanah diambil dari 6 titik lokasi dengan ukuran 1km x 2km, selanjutnya dilakukan preparasi untuk pengukuran unsur logam dengan menggunakkan X-Ray Fluorescence (XRF), uji kandungan C-Organik dan pH. Hasil pengujian XRF menunjukkan bahwa daerah aluvial (Inseptisol) memiliki kandungan Mg dan C-organik lebih tinggi daripada tanah Ultisol dimana rata-rata kandungan Mg >18% dan C-Organik >14% serta memiliki kandungan Al dan Si lebih rendah, dimana Al <20% dan Si <25%. Untuk nilai C- Organik tanah inseptisol (aluvial) memiliki C-organik lebih tinggi (>14%) dan pH lebih rendah (<5) dibandingkan dengan tanah ultisol. Dari hasil pengujian kandungan tanah diharapkan pelaku pertanian pada daerah tersebut dapat mengetahui gambaran kandungan tanah dengan cara melakukan pencocokan pendekatan terhadap sampel tanah yang telah dilakukan pengujian pada penelitian ini.

Abstract

Desa Bedeng Rejo dikenal sebagai salah satu daerah yang berpotensi dalam terjadinya tanah longsor. Metode Very Low Frequency (VLF) digunakan untuk identifikasi bahaya tanah longsor berdasarkan parameter konduktivitas batuan yang didukung kemiringan lereng (slope). Penelitian ini dilakukan menggunakan T-VLF dengan panjang lintasan 200 meter, jarak antar titik ukur 10 meter dan frekuensi pengukuran sebesar 22200 Hz (Jepang). Jenis pengukuran VLF yang digunakan yaitu mode tilt-angle. Ditemukan anomali konduktif yang berada pada rentang 100 - 120 meter dan di bawah permukaan bumi pada 10 - 40 meter dan 170 - 190 meter dengan kedalaman 10 - 30 meter. Perhitungan kemiringan lereng pada lintasan VLF, didapatkan pada jarak 100 – 120 meter yaitu 25% dan pada jarak 170 – 190 meter yaitu 12,5 - 16,67% merupakan lahan dengan kemiringan lereng curam, yang rentan terhadap bahaya tanah longsor, dan mudah tererosi.
