Penelitian ini adalah untuk menganalisis nilai faktor aman lereng dan menghitung
stabilitas lereng menggunakan dinding penahan tanah dengan perhitungan manual.
Metode yang digunakan adalah metode Fellenius dan Bishop. Dari hasil analisis
perhitungan manual, didapatkan nilai faktor aman lereng eksisting dengan metode
Fellenius dan Bishop masing-masing sebesar 0,7296 dan 1,0637. Setelah dilakukan
penanggulangan menggunakan dinding penahan tanah dengan dimensi tinggi 2
meter dan tebal 1,7 meter didapatkan nilai stabilitas terhadap geser yaitu SF =
2,3871 ? 2 (aman) pada kondisi normal. Stabilitas terhadap guling pada kondisi
normal yaitu SF = 2,2502 ? 2 (aman). Stabilitas terhadap geser pada kondisi
gempa yaitu SF = 2,1081 ? 2 (aman). Stabilitas guling pada kondisi gempa yaitu
SF = 2,054 ? 2 (aman).. Penanggulangan menggunakan dinding penahan tanah
cukup efektif terhadap meningkatnya nilai faktor aman, sehingga penanggulangan
menggunakan dinding penahan tanah cukup stabil jika diterapkan di lokasi
penelitian.

abstract

Citraland, which is located in a hilly area, has steep contours and different
elevations. So the area has the potential for landslides. This study was to analyze
the value of the slope safety factor and calculate the slope stability using a retaining
wall with manual calculations. The method used is the Fellenius and Bishop
method. From the analysis of manual calculations, the value of the existing slope
safety factor using the Fellenius and Bishop methods was 0.7296 and 1.0637,
respectively. After countermeasures using a retaining wall with dimensions of 2
meters high and 1.7 meters thick, the value of stability against shear is obtained,
namely SF = 2.3871 2 (safe) under normal conditions. Stability against rolling
under normal conditions is SF = 2.2502 2 (safe). Stability against shear in
earthquake conditions is SF = 2.1081 2 (safe). Overturning stability in earthquake
conditions is SF = 2.054 2 (safe). Countermeasures using retaining walls are quite
effective in increasing the value of the safety factor, so countermeasures using
retaining walls are quite stable if applied at the research site.
