Pembangunan infrastruktur Fly Over Gelumbang Lanjutan menghadapi tantangan kestabilan MSE-Wall pada kondisi tanah heterogen Muara Enim. Penelitian ini bertujuan menganalisis kestabilan internal dan eksternal MSE-Wall menggunakan data geoteknik lapangan untuk memverifikasi kesesuaian dengan SNI 8460:2017. Pendekatan kuantitatif deskriptif-analitik diterapkan pada populasi seluruh struktur MSE-Wall dengan sampel purposive station kritis (STA 60+200 hingga 60+550). Instrumen mencakup SPT, CPT, CSL, PDLT, dan analisis GEO5 dengan metode Bishop-Spencer. Hasil menunjukkan faktor keamanan eksternal (guling 11.38, geser 6.54) dan internal (pullout 37.77, tensile 2.13) memenuhi standar statis/seismik. Kesimpulan merekomendasikan pengawasan timbunan dan drainase optimal untuk proyek serupa.
