Abstract
The development of the Patimban Access Toll Road faces the challenge of soft soil conditions that require embankment reinforcement. This study aims to comparatively analyze the stability and deformation of the embankment using three types of geosynthetics: geotextile, geogrid, and geocell. The analysis was performed using numerical modeling with the Limit Equilibrium Method (LEM) to calculate the Factor of Safety (FS) and the Finite Element Method (FEM) to analyze deformation under static and seismic load conditions. The stability analysis results show that under static loads, all reinforcements met the requirement (FS > 1.30), with Geocell providing the highest FS (1.53). However, under seismic loads, none of the alternatives met the safety requirement (FS < 1.10). The deformation analysis under static loads indicates that Geocell reinforcement was the most effective in reducing vertical settlement (17.2 mm). In conclusion, Geocell is the superior choice for static stability and deformation control, but further analysis is required for the seismic-resistant design of all reinforcement alternatives. Keywords : Embankment, Geosynthetics, Slope Stability, Deformation, Factor of Safety, Finite Element Method, Limit Equilibrium Method. Pembangunan Jalan Tol Akses Patimban menghadapi tantangan kondisi tanah lunak yang menuntut perkuatan timbunan (embankment). Penelitian ini bertujuan untuk menganalisis secara komparatif stabilitas dan deformasi timbunan menggunakan tiga jenis geosintetik: geotekstil, geogrid, dan geocell. Analisis dilakukan dengan pemodelan numerik menggunakan Limit Equilibrium Method (LEM) untuk menghitung Faktor Keamanan (FK) dan Finite Element Method (FEM) untuk menganalisis deformasi pada kondisi beban statis dan seismik. Hasil analisis stabilitas menunjukkan bahwa pada beban statis, semua perkuatan memenuhi syarat (FK > 1,30), dengan Geocell memberikan FK tertinggi (1,53). Namun, pada beban gempa, tidak ada alternatif yang memenuhi syarat keamanan (FK < 1,10). Analisis deformasi pada beban statis menunjukkan perkuatan Geocell paling efektif mengurangi penurunan vertikal (17,2 mm). Kesimpulannya, Geocell merupakan pilihan superior untuk stabilitas statis dan kontrol deformasi, namun diperlukan analisis lebih lanjut untuk desain tahan gempa pada semua alternatif perkuatan.
