Abstract

Ground Penetrating Radar adalah metoda geofisika yang dikembangkan sebagai salah satu metode alternatif untuk penelitian geologi bawah permukaan dangkal yang menggunakan prinsip dari gelombang elektromagnetik (EM) dan memiliki hasil yang rinci. Metode Ground Penetrating Radar (GPR) digunakan karena memiliki resolusi yang tinggi dan tidak bersifat merusak. Prinsip GPR memanfaatkan pantulan gelombang elektromagnetik untuk menunjukkan perbedaan konstanta dielektrik lapisan. Penelitian ini dilakukan di lapangan TR,daerah Gresik dengan menggunakan 26 lintasan yang diolah dengan menggunakan software MAT-GPR dimana akan dilalui berbagai proses seperti Basic Handling, Filtering dan Imaging). Berdasarkan hasil penelitian diketahui bahwa hasil pengukuran georadar dapat menunjukkan keberadaan pipa di bawah permukaan melalui identifikasi anomali hiperbola pada setiap lintasan, namun ada beberapa lintasan yang tidak dapat terlihat dengan jelas anomaly pipa gas nya. Hal ini dikarenakan tidak terlihatnya anomali hiperbola dan karena tertutup oleh barrier beton diatasnya. ================================================================================================ Ground Penetrating Radar is a geophysical method developed as an alternative method for shallow subsurface geological research that uses the principle of electromagnetic waves (EM) and has detailed results. The Ground Penetrating Radar (GPR) method is used because it has a high resolution and is non-destructive. The GPR principle utilizes the reflection of electromagnetic waves to show differences in the dielectric constant of the layers. This research was conducted using 26 paths that were processed using MAT-GPR software where various processes such as Basic Handling, Filtering and Imaging will be used. Based on the research results, it is known that the results of georadar measurements can indicate the presence of pipes below the surface through the identification of hyperbolic anomalies on each path, but there are some lines that the pipe anomaly cannot be clearly seen. This is because the hyperbolic anomaly is not visible and because it is covered by a concrete barrier above it.
