Investigasi Potensi Agregat Geoteknik Dengan Metode Geolistrik

Abstract

Geotechnical Aggregate are rocks that can be used as material for a wide range of construction
engineering purposes. The need for geotechnical aggregates increased along with the rapid
development. Required sources of aggregate qualified engineering was good, close to the project site
and has large reserves. This research will be carried out an investigation to get to the source of
geotechnical aggregate surveying of Geology and Geophysics measurements. Geophysical
measurement is working by using of Geoelctric methods with Schlumberger configuration. Geological
survey result obtained is that the material consists of geotechnical aggregate are QTV , Qtvl and TMV ,
composition form clastica volcanic rocks , breccias , lava , tuff andesite to basalt. Result of
Geoelectric measurements showed that the potential for geotechnical aggregate form Alluvial rocks
having resistivity values between 2-20 ohm meter , whereas the geotechnical aggregate form intrusive
rocks is 30-80 ohm meter . Resource potential Probable amounted to 5,742,453 m³ .
