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

Kota Sungai Penuh dan sekitarnya merupakan wilayah dengan tingkat kerentanan seismik tinggi karena dilalui segmen aktif Sesar Siulak serta didominasi endapan sedimen lepas Formasi Pengasih. Penelitian ini bertujuan untuk mengidentifikasi lapisan tanah yang berpotensi mengalami deformasi dan likuifaksi dengan menggunakan metode mikrotremor Horizontal to Vertical Spectral Ratio (HVSR). Data rekaman mikrotremor dianalisis untuk memperoleh distribusi Ground Shear Strain (GSS) serta ketebalan sedimen pada beberapa titik pengukuran di Kota Sungai Penuh. Hasil menunjukkan bahwa ketebalan sedimen bervariasi antara 5 hingga 105 meter, sedangkan nilai GSS berada pada kisaran 8,10×10⁻⁶ hingga 1,10×10⁻⁴. Zona dengan GSS tinggi ditemukan di Bukit Tanco (Koto Iman dan Koto Petai), yang mengindikasikan pengaruh dominan Sesar Siulak terhadap deformasi tanah. Nilai GSS maksimum masih berada di bawah ambang regangan tanah pemicu likuifaksi (10⁻²–10⁻¹), sehingga pada kondisi gempa moderat tidak terdapat indikasi likuifaksi. Namun, dengan mempertimbangkan berbagai literatur yang menyebutkan bahwa likuifaksi dapat terjadi pada percepatan tanah puncak (PGA) serendah 0,07–0,10 g, wilayah Kota Sungai Penuh tetap berpotensi mengalami deformasi signifikan apabila terjadi gempabumi besar. Penelitian ini menegaskan perlunya mikrozonasi seismik lebih lanjut serta integrasi dengan data geoteknik untuk mendukung perencanaan pembangunan dan mitigasi bencana di wilayah tersebut.

Abstract

Research has been carried out to carry out soil vulnerability analysis at the Faculty of Science and Technology, Jambi University. The construction of buildings at the Faculty of Science and Technology has necessitated an analysis of the vulnerability of the land around the buildings at the Faculty of Science and Technology. Based on the regional geology in this area, the Muara Enim formation (TMPM) is formed in the Tertiary age which is composed of rocks from interbedded tuffaced sandstones with tuffaced mudstones, interbedded quartz sandstones with quartz mudstones, interbedded with coal and iron oxide. The rocks formed in this formation are a type of sedimentary rock. To carry out soil vulnerability analysis, the HVSR method is applied to measure microtremors. Microtremors are a geophysical method that uses very small and continuous ground vibrations. This HVSR method is a passive seismic method using three components, namely 2 horizontal components and 1 vertical component. Microtremor measurements on the ground were carried out at 6 points around the building. The results obtained from microtremor measurements using the HVSR method are the natural frequency (f0), amplification factor (A0) and Seismic Vulnerability Index (Kg). The natural frequency (f0) value ranges from 1.30-1.82 Hz, the amplification factor (A0) value ranges from 1.69 - 3.28 times and the seismic vulnerability index (kg) value ranges from 1.814167 to 5.948834 x 10^-6 s^2/cm. Based on the Kanai classification, a frequency value < 2.5 HZ includes soil type IV and soil type II with Alluvial Rock lithology formed from delta sedimentation, top soil, mud. With a depth of 30 meters or more. This area has a very thick surface sediment, more than 30 meters. Based on the classification according to Setiawan, the amlification factor is classified as low (A0<3) to medium (3<A0<6). A low to moderate amplification factor indicates that the rock that makes it up is compact/hard. Based on the Refrizon Classification, the Seismic Vulnerability Index value is in the low (kg<3) to medium (3<kg<6) category. The seismic vulnerability index is low to medium, meaning that if a shock occurs there will be no damage because the vulnerability value is medium - low. Based on these three parameters, it can be concluded that the land around the FST building is still classified as safe from shocks.

Abstract

This research was conducted to determine the site class of the soil in the Tanah Kampung District in Sungai Penuh City. In this case, the method used is the HVSR microtremor method. HVSR is a method of comparing the spectrum of the horizontal component to the vertical component of a microtremor wave that recorded by seismograph. HVSR parameters were used to calculated shear wave velocity (Vs30) to defined site class. It reveals this areas classified in site class SC and SD. The area is predominantly composed of SD. This areas are characterized by soft sediments that require special handling if heavy infrastructure development is planned above them. This can be done by compacting the soil layers and mixing them with limestone.

Abstract

Jambi Luar Kota is one of the sub-districts with an increasing population density and development level. It can be seen in the last 10 years (2010-2020), 39 populations/km2 with a total population of 62,687 people. The increase in population density impacts infrastructure development, which also increases. The site class maps need to be considered for infrastructure development by considering the development rules in accordance with SNI 1726:2019. This study used the Multichannel Analysis of Surface Wave (MASW) method, which measures variations in surface wave velocity with 21 lines. The average value of the shear wave velocity at a depth of 30 m MASW measurements ranged from 153.24 m/s - 420.86 m/s, consisting of SC site class, SD site class, and SE site class.  SC site class with a Vs30 value of 358.88 m/s-420.86 m/s was found on the east side of the middle part of the Jambi Luar Kota Sub-district. Meanwhile, the SD site classes are evenly distributed in the Jambi luar Kota Sub-district.  The SE site class is located on the north and east sides of the Jambi Luar Kota Sub-district with a Vs30 value of 153.24 m/s, which in this case is supported by geotechnical data in the form of water content (w) (43.03%), plasticity index (PI) (23.26) and a shear strength test of 17,652 kPa.  The area with a low Vs30 value (<175 m/s) is an area that has the potential to get relatively more significant shocks when ground movement occurs.
