IDENTIFICATION OF WATER PIPES LINE IN KALIDOH AREA USING MICROTREMOR METHOD

Abstract

In maintaining underground water pipes are needed to determine the exact location of the pipe. Microtremor method is one of the geophysical methods that can be used to find out the location of objects under the surface. The basic principle of the microtremor method is to use natural vibrations after then detect it using a seismometer. This study aims to identify the location of underground water pipes laterally. Data retrieval of this research was conducted in the Kalidoh area by taking 24 measurement points for 10 minutes at each point. The measurement data is processed by the HVSR method so that the H / V curve shows the frequency value and amplification. At a frequency of 3 Hz there is a circle pattern on each line with an amplification range of 1.4 to 1.75. The fence diagram is used to model all lines so that it is easier to interpret.
