Metode Geolistrik untuk Mementukan Lapisan Keras di Jalan Poros Sungai Alam – Selat Baru Sebagai dasar Pembangunan Ruko dan Rumah

Abstract

Sungai Alam – Selat Baru Street area located on the Bengkalis island where the island of Bengkalis consists of a layer of peat. This layer of peat we know is a soft layer so it is dangerous if we build a building on this layer. Sungai Alam – Selat Baru Street area at the moment is intense in the construction phase of the building in this area needs to be reviewed geotechnique as input for the new construction of buildings in the Sungai Alam – Selat Baru Street area. This research uses the Geo Electrical survey uses Schlumberger configuration method to obtain subsurface resistivity data. From the measurement result of Geo Electrical survey uses Schlumberger configuration method 3 point of measurement in Sungai Alam – Selat Baru Street area resistivity value for peat soil and soft soil is between 5 - 100 ohm with depth 0 m to depth 7 m. As for the hard layer has a resistivity above 100 ohm which is at a depth of 7 meters upwards. The result the authors suggest for the construction of new buildings in Sungai Alam –Selat Baru Street area is to establish a foundation at a depth of 7 meters and above so that new buildings can be more solid.
