Longsor merupakan bencana alam yang sering terjadi dan dapat menyebabkan kerugian besar. Oleh karena itu, prediksi keruntuhan lereng sangat penting untuk mencegah kejadian tersebut, seperti yang dilakukan pada lereng di Desa Trunyan, Kecamatan Bangli, Bali. Untuk memprediksi kerawanan lereng di daerah ini, digunakan metode Linear Discriminant Analysis pada 40 titik lereng dengan dua variabel, yaitu kondisi eksisting lereng dan kemiringan lereng, yang mencakup 40,7 persen dari total faktor yang mempengaruhi stabilitas lereng. Hasil analisis menunjukkan bahwa 28 dari 40 titik lereng, atau 70 persen, terindikasi berpotensi longsor. Nilai Wilks' Lambda yang rendah, yaitu 0,593, dan tingkat signifikansi di bawah 0,01 menunjukkan bahwa hasil penelitian ini valid. Analisis ini menunjukkan bahwa kondisi eksisting dan kemiringan lereng memiliki pengaruh signifikan terhadap stabilitas lereng dan dapat dijadikan indikator dalam evaluasi risiko longsor.
