Abstract

West Sumatra is a province located on the west coast of the island of Sumatra in the middle which has four active fault segments. Nagari Sumani is part of the Sumani Segment line, which makes Nagari Sumani very vulnerable to earthquakes. Efforts are needed too . reduce the impact of the earthquake in Nagari Sumani. This study aims to determine the value of soil vulnerability index (Kg) and soil vulnerability index microzonation (Kg) in Nagari Sumani, specifically Jorong Pinjangek and Jorong Guci, in the area of ​​the Sumani Segment route. The microtremor method of measuring this microtremor can determine the dominant frequency value (f0), amplification factor (A0), and soil susceptibility index value (Kg). Microtremor data was used to obtain the H/V curve at each point of data collection using Geopsy software. Seismic vulnerability index microzonation is carried out using software Surfers 13. The results of this study indicate that the seismic vulnerability index in Nagari Sumani ranges from 3.65 x 10-6 s2/cm to 99.51 x 10-6 s2/cm which has low, medium, to high categories. The results of microzonation of low soil susceptibility index (Kg) are at points 1,2,7, and 8 with a value range of 3.65 x 10-6 s2/cm to 41.02 x 10-6 s2/cm, the medium category is in points 3 and 5 with a value range of 50.02 x 10-6 s2/cm to 54.23 x 10-6 s2/cm, while the high category is at points 4 and 6 with a value range of 63.32 x 10-6 s2/cm to 99.51 x 10-6 s2/cm .

Abstract

In advanced clean energy technologies, rare earth elements (REEs) are an important component. The position of rare earth elements in the future is increasingly strategic so it is necessary to strive to be developed sustainably. At the southern tip of Lampung province, rare earth elements are not yet known. The aims of this study were to analyze the magnetic susceptibility value, composition and percentage of rare earth elements, and the relationship of rare earth elements with magnetic mineral concentrations in pumice at the southern tip of Lampung Province. The method employed is rock magnetic method with Bartington Magnetic Susceptibility Meter Type B and X-Ray Fluorescence. Pumice in the southern region of Lampung Province has diverse magnetic susceptibility values, pumice from Bandar Lampung City has the highest magnetic susceptibility value, while the lowest is in South Lampung Regency. This pumice has antiferromagnetic and ferrimagnetic magnetic properties, and was found to have almost no superparamagnetic grains and also found a mixture of superparamagnetic and coarse grains. The composition of rare earth elements contained in pumice at the southern tip of Lampung Province obtained 3 rare earth elements, samples from Bandar Lampung City contained europium, cerium, and yttrium elements and samples from South Lampung Regency contained europium and yttrium elements. Rare earth elements and magnetic mineral concentration have a relationship, the obtained values decrease with increasing percentage of rare earth elements.

Abstract

Rare earth elements are part of one of the strategic minerals and are included in the "critical minerals". Concentrations of rare earth elements are economically precious deposits that can be used as mining commodities. Pumice is the result of volcanic eruptions and it is one of the minerals containing the rare earth elements, one of which is found in Sigura-Gura, North Sumatra. The research aims to determine the composition of rare earth elements, the relationship between rare earth elements and magnetic mineral concentration, and to determine the concentration of magnetic minerals in pumice in Sigura-gura. The method employed is rock magnetic method with Bartington Magnetic Susceptibility Meter Sensor type B (MS2B), and X-Ray Fluorescence (XRF). Results indicated that Sigura-Gura pumice samples, and Sigura-Gura Waterfall have quite varied magnetic mineral concentrations with a range of values from 111,3 x 10-8m3/kg to 349,9 x 10-8m3/kg, with antiferromagnetic magnetic properties and grain types with almost no SP grains. Samples of Sigura-Gura pumice contain elements of Eu, Ce, and Y, while samples from Sigura-Gura Waterfall contain elements of Eu and Y. There is a correlation between the amount of magnetic minerals and rare elements, and the more elements are present in a sample, the lower the value that is produce, and the greater the percentage of elements obtained, the smaller (%) is obtained.

Abstract

Indonesia is a country prone to earthquake disasters, because Indonesia is located in the collision area between plates, and one of the areas in Indonesia where plate movements often occur is Mentawai. Analysis of waveform data on the 2022 earthquake in the Mentawai region was carried out to determine the type of fault. The data used in this research is local seismic data downloaded from webdc.eu. Seismic data was analyzed using waveform inversion method implemented in ISOLA program. In the ISOLA program, data processing is carried out which includes: inputting 3-component seismic data, earthquake info events, selecting stations, green functions, performing inversion, and displaying results in the form of tensor moment values, strike, dip, and rake values. From the data analysis, the moment tensor value is obtained with the range of each component of M11 is -8.348 to -3.673, M22 is 0.710 to -2.037, M33 is 7.639 to 5.710, M31 is 2.050 to 3.761, M32 is 3.484 to -5.672, M12 is -2.751 to 2.455. Then the inversion results obtained in the form of fault parameters, namely strike, dip, and rake for two nodals that will be analyzed to determine the fault plane. Based on the moment tensor value, it is found that the type of earthquake fault in 2022 in Mentawai region is dominated by reverse fault and oblique fault patterns.
