Abstract

Identified subsurface composition remains one of the important things in development, such as finds out potential that is below the surface, this research in Institut Teknologi Kalimantan Campus (ITK). This study aims to identify distribute potential values and finds out the source of anomalies in the ITK Campus area. This study uses the Self-Potential method with a fixed-base technique. The data obtained in the form of potential difference (delta V) data, base potential data and measurement point coordinates. The data was corrected by daily base variation, daily correction and reference correction. After obtaining a potential value from the correction at each measurement point, the data processing was done using surfer 11 software. The results of data processing were obtained isopotential contour map and qualitative interpretation which could be seen distribution of potential different values. On the isopotential contour map, slicing of two cross sections selected indicates the source of anomaly. Anomalous potential values of 45 mV to -55 mV indicated anomalous sources namely electrolyte potential in groundwater with positive anomaly values negative up to hundreds of mV. And, there was a potential for a liquid flowwith a positive and negative anomaly ≤ 100 mV

Abstract

Microtremor analysis has been done in the Sepaku Sub-District as a part of the New Capital City of Indonesia. This study aims to determine the characteristics of microtremors in the Sepaku Sub-District using Spectrum Analysis and Time-Frequency Analysis (TFA). Data in this study were taken using a seismometer on the 18 measurement points. The data were processed using default analysis from Geopsy software. Spectrum analysis and TFA used Fourier Transform to change time domain data into the frequency domain. Both analysis ways result in the characteristic microtremor data in the research area. The spectrum analysis data obtained shows two frequency ranges with maximum peaks: middle-frequency (5-8.8 Hz) and high-frequency (11.5-17.6 Hz). Afterward, the TFA shows similar results, where the characteristics of microtremor data are divided into two zones. The maximum peak occurs at the middle-frequency range of 5-10 Hz, and the high frequency ranges above 10 Hz

Abstract

Sinabung Volcano is located in the Karo Highlands, Karo Regency, North Sumatra, Indonesia, with a peak of 2460 meters above sea level. This volcano experienced an increase in volcanic activity in the April-October 2021 period, so it is necessary to analyse volcanic seismicity to determine the hypocenter distribution of the volcano. This study aims to determine the hypocenter distribution and classification of volcanic earthquake types based on seismogram recording data of Sinabung Volcano at four stations, namely LKW, BGR, MDD and SGR stations. The method used in this research is Geiger's method with adaptive damping (GAD) to determine the distribution of hypocenters. The results showed that the hypocenter distribution gathered below the crater centre with depths from 0.172 km to 7.139 km. The determination of the hypocenter distribution of volcanic earthquakes is expected to provide information on the depth of the earthquake to determine the movement of magma and the characteristics of events that occur during the pre-eruption process of Sinabung Volcano so that this data can be used for mitigation decision making when there is an increase in the activity of Sinabung Volcano.
