Studi bawah permukaan menggunakan metode geolistrik resistivitas dan ground penetrating radar (GPR): Studi kasus di area pembangunan gedung kampus STMKG Tanah Tinggi Tangerang
Abstract
The bedrock is an essential component in the planning of high-rise building construction. The depth of the bedrock and the classification of the rock types above it can serve as crucial considerations in the construction planning of high-rise buildings in a particular area. The presence of bedrock provides guidance for determining the foundation of the building's structure. Bedrock, characterized by its hard texture, also serves as a reference for distributing loads on the ground and understanding the effects of infrastructure development on its surface. In this research, the author focuses on utilizing two methods, namely Electrical Resistivity Tomography (ERT) and Ground Penetrating Radar (GPR), to classify the types of rocks beneath the Earth's surface and identify the bedrock. The primary objective of this study is to identify the depth of the bedrock and classify the types of rocks that constitute the subsurface. Based on the analysis of geoelectric resistivity and ground-penetrating radar data, it can be concluded that the construction area of STMKG Tanah Tinggi Campus in Tangerang has the following layers: the first layer consists of sandy soil, backfill soil, and topsoil with resistivity values ranging from 1.28 Ohm to 4.64 Ohm. The subsequent layer is composed of soft soil with resistivity values ranging from 4.64 Ohm to 7.14 Ohm, and medium soil with resistivity values ranging from 11.0 Ohm to 26.0 Ohm.
