Abstract
Sungai Porong merupakan salah satu anak sungai yang termasuk dalam kawasan DAS Sungai Brantas. Sungai Porong yang terletak diantara 2 kota yang merupakan kota padat penduduk serta kawasan industri, sehingga pengaruh aktivitas antropogenik dapat mempengaruhi keadaan Sungai Porong. Ilmu kemagnetan lingkungan yaitu ilmu yang mengkorelasikan antara pencemaran lingkungan dengan nilai sifat magnetik pada sampel sedimen. Ilmu kemagnetan lingkungan banyak diterapkan dalam bidang mengidentifikasi pengaruh logam berat terhadap sedimen. Metode yang digunakan di penelitian ini adalah pengukuran suseptibiltias magnetik, analisis AAS (Atomic Absorption Spectroscopy), analisis XRD (X-Ray Diffraction) dan analisis SEM-EDS (Scanning Electron Microscopy-Energy Dispersion Spectroscopy). Pada penelitian tugas akhir ini dilakukan identifikasi sifat magnetik pada sedimen Sungai Porong. Hasilnya nilai suseptibilitas magnetik yang tinggi. Mineral dan kandungan logam berat pada sedimen juga dapat dideteksi.

The Porong River is one of the tributaries included in the Brantas River Basin (Watershed) . The Porong River is located between 2 cities which are densely populated cities and industrial estates, so the influence of anthropogenic activities can affect the condition of the Porong River. Environmental magnetism is the study that correlates between environmental pollution and the value of magnetic properties in sediment samples. Environmental magnetism is widely applied in the field of identifying the effects of heavy metals on sediments. The method used in this research is the measurement of susceptibility magnetic , AAS analysis (Atomic Absorption Spectroscopy), XRD analysis (X-Ray Diffraction) and SEM-EDS analysis (Scanning Electron Microscopy-Energy Dispersion Spectroscopy). In this final project, the identification of magnetic properties in the Porong River sediments was identified. The result is a high magnetic susceptibility value. Minerals and heavy metal content in sediments can also be detected.
