Abstract
Korosivitas tanah merupakan salah satu masalah yang berdampak pada kerusakan lingkungan dan infrastruktur. Pipa yang terletak pada subsurface menjadi salah satu contoh dari infrastruktur yang rentan terhadap korosi, maka dari itu pemetaan subsurface sangat dibutuhkan untuk mengetahui keadaan lingkungan korosif bawah permukaan. Pada tugas akhir ini dilakukan penelitian mengenai pemetaan lingkungan korosi bawah permukaan dengan menggunakan metode Self Potensial pada daerah unit 7 dan 8 PT.IPMOMI. Pengukuran self potensial dilakukan 2 kali yaitu pada awal penelitian dan 15 hari setelahnya. Dari hasil pengukuran SP kemudian dikorelasi dengan nilai native potensial sehingga didapat range nilai korosivitas tanah. Nilai SP -120 hingga 40 memiliki tingkat korosivitas sedang, dan nilai SP 40-220 memiliki tingkat korosivitas yang sangat tinggi. Pada lokasi penelitian tingkat korosivitas yang sangat tinggi berada pada sisi utara dari lintasan dan semakin rendah pada sisi selatan yang disebabkan oleh adanya intrusi air laut pada sisi utara dari lokasi penelitian.
============================================================
Soil corrosivity is one of the problems that impact on the environment and infrastructure damage. Pipes located at subsurface are one of a corrosion prone infrastructure, hence subsurface mapping is needed to determine the state of the subsurface corrosive environment. In this final project conducted research on mapping the environment of subsurface corrosion by using Self Potential method on unit 7 and 8 PT.IPMOMI. Self-potential measurements were made twice at the start of the study and 15 days afterwards. From result of SP measurement then correlated with native potential value and as result range of soil corrosivity value is obtained. The values of SP-120 to 40 have moderate corrosivity, and SP 40-220 has a very high degree of corrosivity. At the research site, very high level of corosivity lies on the northern side of the track and lower on the southern side caused by the intrusion of sea water on the northern side of the research site.
