Abstract
Lereng merupakan suatu konstruksi tanah dengan ketinggian elevasi yang berbeda, sehingga menghasilkan komponen gravitasi yang cenderung menggerakan massa tanah menuju ke permukaan yang lebih rendah. Gaya penggerak ini disebabkan oleh beberapa hal, diantaranya adalah gempa. Saat hal ini terjadi energi yang berupa getaran getaran/goncangan tanah yang diawali oleh patahnya lapisan tanah/batuan di dalam kulit bumi dan diikuti pelepasan energi secara mendadak. Gempa juga salah satu faktor untuk menyebabkan ketidakstabilan lereng. Energi tersebut terakumulasi secara bertahap di lokasi sumber gempa sebagai energi potensial. Analisis kestabilan lereng akibat gempa ini menggunakan program plaxis v8.6 yang dapat menghitung faktor keamanan dengan menggunakan metode finite element atau metode elemen hingga. Pada perhitungan ini membutuhkan beberapa parameter agar memenuhi data yang diperlukan antara lain : Young Modulus(E) ,Poisson’s Ratio(v), Sudut Geser(φ), Kohesi(c), γsat, γunsat, kx,y. Dari hasil penelitian perhitungan menggunakan plaxis dilakukakan dengan cara memvariasikan nilai frekuensi.

Slope is a soil construction with different elevation heights, resulting in a gravity component that tends to move the soil mass towards a lower surface. This driving force is caused by several things, one of which is an earthquake. When this happens, energy is in the form of vibrational vibrations/ground shaking which is initiated by the breaking of the soil/rock layers in the earth's crust and followed by a sudden release of energy. Earthquake is also one of the factors to cause slope instability. The energy accumulates gradually at the location of the earthquake source as potential energy. The slope stability analysis due to this earthquake uses the Plaxis v8.6 program which can calculate the safety factor using the finite element method or the finite element method. This calculation requires several parameters to meet the required data, including: Young Modulus(E) , Poisson's Ratio(v), Shear Angle(φ), Cohesion(c), sat, unsat, kx,y. From the research results, calculations using plaxis are carried out by varying the frequency value
