APLIKASI ELECTRICAL RESISTIVITY TOMOGRAPHY (ERT) UNTUK MENENTUKAN INTERFACE AIR TAWAR DAN AIR ASIN DI PESISIR PULAU TERNATE

نویسندگان

چکیده

Pulau Ternate merupakan pulau gunungapi kecil, dimana terjadinya intrusi air asin lebih cepat pada kecil. Di samping itu, seiring dengan pertambahan penduduk maka kebutuhan tawar akan semakin meningkat, sehingga eksploitasi berlebihan memicu asin. Intrusi penyusupan ke dalam akuifer di pesisir. Oleh karena itu perlu dilakukan penelitian untuk mengidentifikasi zona daerah penelitian. Salah satu metode geofisika yang dapat memberikan informasi bawah permukaan menggunakan geolistrik Electrical Resistivity Tomography (ERT). Metode (ERT) gambaran vertikal dan lateral 2D dari kemampuannya mendeteksi variasi resistivitas suatu formasi. Pada ini pengolahan data software ResIPy. Penelitian pesisir lokasi Tabam, Taman Eva, Togafo. Berdasarkan hasil diperoleh, menunjukkan nilai 2,8 Ωm – 198,7 Ωm. penampang diduga bahwa lintasan Tabam Eva mengalami Kedalaman interface teridentifikasi yaitu 28 m, adalah 25 Togafo m.

Anatomy of terminal moraine segments and implied lake stability on Ngozumpa Glacier, Nepal, from electrical resistivity tomography (ERT)

Moraine-dammed lakes at debris-covered glaciers are becoming increasingly common and pose significant outburst flood hazards if the dam is breached. While moraine subsurface structure and internal processes are likely to influence dam stability, only few sites have so far been investigated. We conducted electrical resistivity tomography (ERT) surveys at two sites on the terminal moraine complex...
