Abstract

Gerakan tanah di Desa Gerbosari berpotensi berdampak pada pemukiman dan fasilitas umum. Informasi mengenai litologi memiliki peran yang penting untuk mitigasi gerakan tanah yang akan terjadi. Penelitian ini bertujuan untuk mengetahui litologi dan zona gerakan tanah dengan metode geolistrik konfigurasi Wenner. Pengukuran geolistrik dilakukan sebanyak 7 lintasan pada zona berpotensi mengalami gerakan tanah. Panjang lintasan yang digunakan 300 m (5 lintasan), 260 m (1 lintasan) dan 240 m (1 lintasan). Pengolahan data menggunakan software Res2Dinv dan Surfer. Hasil pengolahan dari Res2Dinv berupa model penampang 2 dimensi yang menunjukkan nilai resistivitas daerah penelitian yaitu sebesar 0,481-636 Ωm. Daerah dengan zona rentan gerakan tanah yaitu pada resistivitas 0,481-151 Ωm (formasi Kebobutak) dan 0,481-8,52 Ωm (formasi Jonggarangan) yang diduga mengandung lempung dan batu pasir. Zona gerakan tanah tersebar hampir seluruh daerah penelitian, mulai dari kawasan penduduk hingga persawahan pada kedalaman 2,50-62,5 m. Land movement in Gerbosari Village has the potential to have an impact on settlements and public facilities. Information about lithology has an important role to mitigate soil movement that will occur. This study aims to determine the lithology and zone of ground movement with the Wenner configuration geoelectric method.

Abstract

Being in an active fire lane means that Indonesia has geothermal potential. The geothermal research location is in the Tempuran area, Magelang Regency. The method used is by using alignment in the National Digital Elevation Model (DEMNas) data and calculating it using the Fault Fracture Density (FFD) method, the result of which is a contour map. This research aims to identify the existence of geothermal manifestations with FFD values. The research results show that the FFD value in the Tempuran geothermal manifestation area varies between 0.09 - 1.80 km/km2. The FFD value shows that the Tempuran geothermal manifestation is in a low density zone. There is no direct correlation between the presence of geothermal manifestations and the FFD value. The Tempuran geothermal manifestation is thought to be related to geological formations composed of volcanic rock and related to an aquifer system, as well as faults that trend northwest-southeast.

Abstract

Kabupaten Simalungun, merupakan salah satu kabupaten di provinsi Sumatera Utara. Berbatasan dengan Kabupaten Toba Samosir dan Danau Toba di sebelah Selatan, daerah ini cukup rawan terhadap bencana tanah longsor. Penelitian ini bertujuan untuk mengetahui korelasi dan determinasi Fault Fracture Density dengan membandingkan jumlah kejadian tanah longsor pada kawasan penelitian. Dari kedua titik tanah longsor diketahui pada titik pertama (Bukit Dolok Simarbalatuk) banyak terjadi aktivitas tanah longsor dibandingkan dengan titik kedua (Jalan Josep Sinaga) yang hanya terjadi sekali. Berdasarkan hasil interpretasi korelasi dan determinasi antara Fault Fracture Density dengan jumlah kejadian tanah longsor didapatkan hubungan positif yang sangat rendah serta menunjukkan bagaimana nilai Fault Fracture Density dapat menjadi faktor banyaknya jumlah kejadian tanah longsor sebesar 2.7%. Curah hujan yang tinggi menjadi faktor yang cukup berpengaruh terhadap bencana tanah longsor pada kawasan penelitian.

Abstract

Arjuna Road in Kalongan Village, East Ungaran, which connects Semarang Regency with Demak Regency, has been cut off due to a landslide. Lithology as an internal controlling factor of landslide occurrence is important to be investigated. Research on the disaster has been conducted to determine the magnetic field anomaly and to interpret subsurface lithology using the geomagnetic method. The research was conducted on the landslide zone at Arjuna Road and its surrounding area using the geomagnetic method with looping data acquisition. The research area includes residential areas and plantation areas of residents with a research area of 1.3 × 0.8 km2 with a total of 104 measurement points. Through the results and analysis of the research, it can be determined that the magnetic field anomalies in the research area range from 17.1 - 882.2 nT where the landslide zone dominantly has a high anomaly indicating the closer the area is to bedrock, and for residential areas and local plantations, the magnetic field anomalies vary from low to high depending on the topography and sediment thickness in the area. In addition, the subsurface lithology in the study area consists of clay soil, claystone, tuff, and volcanic breccia. The impermeable nature of the tuff and the water-low permeable clay soil causes the boundary between the clay soil and tuff layers to become slippery when water seepage occurs, resulting the landslides.

Abstract

On July 7, 2024, an M4.4 earthquake affected Batang, Warungasem, and Wonotunggal sub-districts, causing minor to major damage to houses. This study intends to conduct macroseismic and microseismic studies in the earthquake-affected zone. Macroseismic analysis involves determining the amount of building damage on the MMI intensity scale, whereas microseismic analysis relies on dominant frequency characteristics (fo), amplification factor (Ao), and local geology. Macroseismic study indicates that the Batang earthquake had an intensity of III-IV MMI. The amount of light-to-heavy building damage does not affect the earthquake intensity (MMI) number. This is because the destroyed structures were constructed in a simplistic manner and were not earthquake-resistant. Microseismic investigation revealed that the Alluvium Plain had the dominating distribution of damage, with fo values <3.4 Hz and Ao >4.8. Aside from building quality, local geological variables have an impact on earthquakes on the surface.

Abstract

This research is motivated by the earthquake phenomena that have occurred in the Yogyakarta area due to the 2006 earthquake. This study aims to determine the earthquake hazard index based on the method developed by BNPB and JICA by making earthquake hazard distribution maps correlated with settlement maps. This research was conducted in Sanden District in the south of Bantul Regency. The BNPB and JICA methods utilize four main parameters, namely shear wave velocity at a depth of 30 meters (Vs30), Ground Amplification Factor (GAF), accelerated ground rock vibration (PGASB) and acceleration of surface ground vibration (PGA). Vs30 is obtained from the inversion method using microtremor measurement data, the Vs30 value is converted into a GAF value using the formula Midorikawa et al (1994), for PGASB it is obtained from the PUSKIM website, based on the earthquake hazard index mapping guide the Vs30 and PGASB values obtained if multiplied then will get the surface PGA value then the surface PGA value is reclassified by the type of class based on the BNPB and JICA methods. The results showed that the value of Vs30 ranged from 154.66 m / s to 260.80 m / s, GAF values ranged from 1.64 g to 2.09 g, PGASB values ranged from 0.52 g to 0.67 g, and PGA values surface ranges from 0.87 to 1.32 g. The earthquake hazard index covers the entire Sanden District with an index value of 1 and the highest distribution of settlements prone to earthquake hazards is in the entire study area.Keywords: Microtremor, Vs30, GAF, surface ground vibration acceleration (PGA), PGASB, earthquake.
