Berdasarkan pengujian lapangan menggunakan alat Dynamic Cone Penetrometer (DCP), tanah di lokasi tersebut memiliki nilai CBR sebesar 2,627%, yang berada jauh di bawah standar minimum 6% sebagaimana ditetapkan dalam Manual Desain Perkerasan Jalan (2017). Tujuan penelitian mencakup penentuan klasifikasi tanah menggunakan sistem USCS, menganalisis pengaruh penambahan bahan stabilisasi berupa abu sekam padi dengan variasi 0%, 5%, 10%, dan 15% dan dilakukan pemeraman 0, 3, 7 hari, serta mengevaluasi perubahan nilai CBR unsoaked setelah proses stabilisasi dilakukan. Hasil pengujian laboratorium menunjukkan bahwa tanah termasuk dalam kelompok OH, yaitu lempung organik dengan plastisitas tinggi, dengan nilai indeks plastisitas (PI) sebesar 19,55% dan nilai CBR awal sebesar 1,192%. Penambahan kombinasi abu sekam padi terbukti mampu menurunkan nilai plastisitas tanah sekaligus meningkatkan nilai CBR unsoaked secara signifikan. Peningkatan terbesar diperoleh pada campuran 10% abu sekam padi yang menghasilkan nilai CBR unsoaked sebesar 14,28% dengan pemeraman 7 hari. Penelitian ini menunjukkan bahwa abu sekam padi pada proporsi yang tepat mampu meningkatkan stabilitas tanah lempung secara efektif.</mods:abstract><mods:classification authority="lcc">TA Engineering (General).
