Potensi Kandas Batuan Berdasarkan Metode Markland, dan Zona Rawan Longsor di Daerah Kaliwader, Kecamatan Bener, Kabupaten Purworejo, Jawa Tengah

Abstract: Daerah penelitian secara administratif berada di Kecamatan Bener, Kabupaten Purworejo, Jawa Tengah. Secara geomorfologi, bentuk lahan daerah tersebut terdiri dari Perbukitan Struktural (S1), Lembah Homoklin (S2), Dataran Alluvial (F1), Tubuh Sungai (F2), dan Dataran Limpah Banjir (F3). Lito-stratigrafi daerah penelitian mulai dari batuan tertua, disusun oleh Satuan Breksi-vulkanik Kaligesing, Satuan Lava-andesit Kaligesing, kedua satuan berumur Oligosen Akhir hingga Miosen Awal, Satuan Batugamping-pasiran Sent… Show more

“…During applying the method, six slopes samples, mainly consisting of volcanic rocks of Kaligesing Formation, situated in Bener District were analyzed. The physical properties of slope constituent rock were also tested by Uniaxial Compressive Strength Test, and by referring to researchers [17], [19], the results are presented in Afterward, RMR was carried out on slope constituent rocks. From the computation of RMR, Kaliwader slopes, Argosari slope, and Wadas slope have an RMR value ranging from 45 to 48, classified as fair rock.…”
