Abstract


Metode Resistivitas merupakan metode yang dapat memberikan informasi mengenai tahanan jenis sebuah media, salah satunya media seperti tanah. Tahanan jenis yang rendah pada tanah tersaturasi fluida dapat mengindikasikan kondisi lingkungan yang konduktif. Lingkungan yang konduktif berpotensi menciptakan korosi pada logam umumnya dan khususnya besi. Permodelan numerik resistivitas-korosivitas digunakan untuk mengkorelasikan parameter resistivitas dengan parameter korosivitas seperti laju korosi. Sehingga dari permodelan numerik tersebut dihasilkan persamaan numerik yang dapat mencitrakan laju korosi yang berpotensi terjadi dari hasil penampang resistivitas. Permodelan numerik resistivitas untuk menganalisis laju korosi ini dapat digunakan untuk melakukan kontroling pipa yang ditanam di bawah tanah. Pada tugas akhir ini dilakukan permodelan resistivitas terhadap laju korosi dari data uji labolatorium terhadap sampel besi AISI 1045 dengan memberikan variasi konsentrasi larutan NaCl terhadap media, dan variasi waktu pengukuran laju korosi. Hasil akhir dari penelitian ini berupa persamaan numerik yang merepresentasikan hubungan antara resistivitas terhadap laju korosi.
