<note>Tanah yang berpotensi mengalami likuefaksi merupakan tantangan serius dalam perencanaan dan konstruksi infrastruktur, terutama di daerah-daerah yang berada di zona rawan gempa. Likuefaksi adalah fenomena di mana tanah berperilaku seperti cairan akibat guncangan seismik, yang dapat menyebabkan penurunan atau kerusakan struktur yang didirikan di atasnya. Penelitian ini bertujuan untuk menganalisis potensi likuefaksi tanah berdasarkan nilai rasio tegangan air pori berlebih (ru) dengan batas sebesar 0,7. Jika nilai rasio tegangan air pori berlebih (ru) lebih besar daripada 0,7 maka tanah tersebut berpotensi likuefaksi. Analisis perbaikan tanah dilakukan menggunakan metode elemen hingga dengan software PLAXIS 3D. Hasil pemodelan menunjukkan bahwa tanah dalam kondisi eksisting mengalami potensi likuefaksi dengan nilai ru > 0,7, sehingga diperlukan perbaikan menggunakan stone column. Hasil analisis menunjukkan bahwa setelah dilakukan perbaikan tanah dengan stone column, nilai ru mengalami penurunan pada variasi spasi 1,5 m dengan diameter 0,7 m, dan ini merupakan hasil yang paling efektif.</note>
