Abstract

Desa Kradinan merupakan salah satu daerah rawan longsor di Kabupaten Tulungagung. Desa Kradinan berada pada Formasi Mandalika yang tersusun oleh batuan mudah mengalami gerakan tanah sehingga berpotensi terjadi longsor. Salah satu cara mengidentifikasi bawah permukaan tanah untuk mengetahui potensi terjadi longsor yaitu dengan metode resistivitas konfigurasi Wenner-Schlumberger. Inversi yang dilakukan menggunakan metode Least-Square Smoothness Constraint (L2-norm model dan error). Hasil inversi digunakan untuk menganalisa kondisi bawah permukaan serta penyebab dan letak bidang gelincir. Hasil interpretasi menunjukkan bahwa Desa Kradinan diduga memiliki potensi longsor jenis rayapan dan runtuhan yang secara berurutan disebabkan oleh keberdaan lapisan breksi diatas lapisan lanau dan keberadaan retakan yang tersaturasi fluida.

Kradinan village is one of the areas prone to landslides in Tulungagung. The village is located on the Mandalika Formation which composed by rocks sensitive to ground movement, thus landslides can occur. One way to determine the potential of landslides is to identify the subsurface using resistivity method Wenner-Schlumberger configuration. Inversions were performed using the method of Least-Square Smoothness Constraint (L2-norm models and error). The inversion results are used to analyze subsurface conditions and the causes or the locations of the landslide bodies. The results indicate that the Kradinan Village have the potential of creeping-type and debris-type landslide which are caused by the presence of breccia layer above the silt layer and the presence of fluid-saturated cracks.
