Abstrak

Secara geografiis, daerah penelitian terletak pada koordinat 0°21'12."- 0° 22' 50."Lintang Utara dan 00°10'53" - 100°33'44.4620" Bujur Timur. Penelitian terletak di daerah koto lamo dan sekitarnya, Kecamatan Kapur sembilan, Kabupaten Sumatera Barat. Tujuan penelitian ini adalah untuk mengetahui tingkat kestabilan lereng pada daerah penelitian dengan menggunakan metorde pemetaan geologi, analisis UCS (Uniaxial Compressive Strength) kekuatan batuan utuh, RMR (Rock Mass Rating) dan Stereografis, dari data lapangan. Terdapat 10 scanline utama yang menjadi objek penelitian. Hasil pemetaan geologi menunjukkan lereng tersebut terdapat batuan batupasir, dari batuan tersebut analisis UCS kekuatan batuan utuh memiliki nilai rata "“ rata dari uji Schmidt Hammer bernilai 13.08, sedangkan nilai densitas sampel batuan nya 25,86 ð¾ð‘â„ð‘š³. Hasil pengukuran tersebut menunjukkan nilai UCS sebesar 19 MPa, termasuk dalam bobot 2 dengan kategori lemah (weak). Kemudian hasil dari analisis RMR (Rock Mass Rating) bernilai 35,4 dengan kelas RMR IV (jelek).
