Abstract

Kabupaten Ponorogo merupakan salah satu daerah yang
sering mengalami longsor. Oleh Karena itu, perlu dilakukan
mitigasi bencana longsor menggunakan metode Self-Potential
(SP). Pengukuran data SP pada lereng Jalan Raya Ponorogo-
Trenggalek KM. 23 dianalisis menggunakan transformasi wavelet
Continous Wavelet Tranform (CWT) untuk mengidentifikasi
kedalaman dan posisi anomali. Hasil interpretasi kualitatif dan
kuantitatif data SP menunjukkan bahwa anomali data SP berupa
anomali monopole dan dipole yang secara berurutan
merepresentasikan adanya fluida dalam rekahan/patahan dan
fluida dalam pori batuan. Kedua fluida tersebut sebagai penyebab
longsor yang bergerak dari arah barat daya menuju timur laut.
Selain itu, kedua anomali tersebut mengindikasikan posisi rawan
longsor, yang memiliki kedalaman 0.6-4.2 meter.
