      "abstract": "Longsor merupakan salah satu bencana yang sering terjadi akibat menurunnya kekuatan geser tanah, khususnya pada lereng dengan kondisi tanah yang kurang stabil dan dipengaruhi oleh air hujan. Penelitian ini dilakukan di Dusun Kedungnongko, Desa Sekar, Kecamatan Sekar, Kabupaten Bojonegoro, dengan tujuan untuk mengetahui karakteristik fisik dan mekanis tanah melalui pengujian direct shear, atterberg limit, berat isi tanah, dan berat jenis tanah. mengetahui pemodelan lereng serta pengaruh infiltrasi hujan terhadap kestabilan lereng, dan mengetahui desain perencanaan perkuatan dinding penahan tanah pada lokasi penelitian. Pengujian laboratorium dilakukan untuk memperoleh parameter tanah berupa kadar air, sudut geser dalam (\u03c6), kohesi (c), batas-batas atterberg, berat isi, dan berat jenis tanah. Berdasarkan hasil pengujian, diperoleh kadar air rata-rata tanah sebesar 58,12%, sudut geser dalam sebesar 1,46\u00b0, dan nilai kohesi sebesar 15,65 kPa. Parameter tersebut digunakan sebagai data masukan dalam pemodelan stabilitas lereng menggunakan perangkat lunak Geostudio dengan metode Bishop untuk mengetahui nilai faktor keamanan (safety factor) lereng pada kondisi normal maupun saat terjadi hujan, baik tanpa perkuatan maupun dengan perkuatan dinding penahan tanah. Hasil analisis menunjukkan bahwa infiltrasi hujan menyebabkan penurunan nilai faktor keamanan lereng, penambahan dinding penahan tanah mampu meningkatkan stabilitas lereng dengan nilai faktor keamanan dari kondisi awal sebesar 1,187 dari kondisi kritis menjadi sebesar 1,505 setelah penerapan tembok penahan tanah kantilever. Penelitian ini diharapkan dapat menjadi acuan dalam perencanaan mitigasi bencana longsor serta rekomendasi teknis desain perkuatan dinding penahan tanah di wilayah studi maupun wilayah lain dengan karakteristik tanah yang serupa.",
