Abstract

Perusahaan air olahan membutuhkan sumberdaya air tanah dengan kualitas yang baik untuk dapat digunakan seagai bahan baku produksi. Namun dari beberapa sumur produksi yang telah dimiliki oleh perusahaan terdapat sumur yang memiliki kualitas air tanah yang kurang baik. Penelitian ini berfokus untuk mengidentifikasi akuifer air tanah dan struktur bawah permukaan pada area penelitian. Untuk identifikasi akuifer air bawah tanah dan stratigrafi area penelitian digunakan metode resistivitas 2D sebagai data primer dan electric well loging sebagai data skunder. Pengukuran Resistivitas 2D konfigurasi Wenner-Schlumberger dilakukan sebanyak 3 lintasan untuk mengidentifikasi pola persebaran air tanah. Data skunder Electric Well Logging digunakan untuk membantu dalam proses interpretasi hasil dan pola stratigrafi area penelitian. Hasil penelitian menunjukkan bahwa nilai resistivitas hasil inversi yang diinterpretasikan sebagai zona akuifer berada pada rentang 1,2 – 6,4 Ohm.m. Terdapat indikasi kandungan air payau dengan nilai resistivitas <1 Ohm.m terdapat di kedalaman 90-100 meter pada lintasan 1, kedalaman 80-90 meter pada lintasan 2, dan kedalaman 30-50 meter pada sisi barat laut lintasan 3. Terdapat anomali seperti struktur pada lintasan 3 yang diinterpretasikan sebagai antiklin.

Water companies need good quality groundwater resources to be used as production raw materials. However, from several production wells that have been owned by the company, there are wells that have poor groundwater quality. This study focuses on identifying groundwater aquifers and subsurface structures in the study area. For the identification of underground water aquifers and stratigraphy of the study area, the 2D resistivity method is used as primary data and electric well logging as skunder data. The Wenner-Schlumberger configuration 2D resistivity measurement was carried out as many as 3 passes to identify groundwater distribution patterns. Electric Well Logging data skunder is used to assist in the process of interpreting the results and stratigraphic patterns of the research area. The results showed that the resistivity value of the inversion results interpreted as an aquifer zone was in the range of 1.2 – 6.4 Ohm.m. There are indications of brackish water content with resistivity values of <1 Ohm.m found at depths of 90-100 meters on line 1, depths of 80-90 meters on line 2, and depths of 30-50 meters on the northwest side of line 3. There are anomalies such as the structure in line 3 which is interpreted as anticline.
