Padahal, jenis batuannya yang tersusun atas napal dan tanah lapukan napal menjadikan wilayah ini berpotensi memiliki resiko kembang susut. penelitian ini bertujuan untuk mengungkapkan potensi kembang susut pada batuan napal dan tanah lapukannya yang berada di wilayah Nanggulan, Kulon Progo. Metode yang digunakan adalah menggunakan pengujian rasio kembang susut/free swell ratio (FSR) yang dikembangkan oleh (Mohan & Goel, 1959). Metode penelitian menggunakan pendekatan kualitatif dan kuantitatif. Nilai FSR untuk sampel napal dan tanah lapukan napal di Formasi Sentolo, Nanggulan adalah sebesar 1,21.

Penelitian ini bertujuan untuk mengetahui nilai faktor keamanan stabilitas lereng setelah menggunakan perkuatan existing pasangan batu dan dinding penahan tanah bronjong dengan bore pile. Parameter tanah yang digunakan adalah model parameter Hardening Soil (HS) Undrained B. Tanah dibagi kedalam tiga lapisan dengan konsistensi lapisan lempung kelanauan bercampur laterit (0-2 m), lempung berpasir (2-6 m), dan batu lempung (6-16 m). Pada analisis stabilitas lereng menggunakan nilai beban lalu lintas sebesar 100 kN/m2 berpengaruh terhadap stabilitas lereng. Dari hasil analisis didapatkan nilai faktor keamanan stabilitas lereng dengan perkuatan existing pasangan batu sebesar 1,346 < 1,5 dimana nilai tersebut dikategorikan tidak aman.

Bandara tersebut menjadi bandara pengumpul serta menjadi bandara transit untuk rute perjalanan dari bandara – bandara kecil di Pulau Jawa ke tujuan Indonesia Timur ataupun Indonesia Barat bahkan luar negeri.

This landslide occurs due to an imbalance of forces acting on the slope or the actuator in the slope area is greater than the resisting force on the slope. Handling needs to be done to avoid landslides, one of which is making a retaining wall. Based on the data obtained from the results of the tests and calculations that have been carried out, the value of the slope safety factor at the research location is 0.397. This value is the value of the unsafe factor of safety (Avalanche). So it is necessary to design a retaining wall with dimensions in between, namely for H = 7 m, H1 = 0.7 m, H2 = 6.3 m, H3 = 1.6 m, H4 = 0.7 m, H5 = 4.9 m, H6 = 2.6 m, H7 = 0.5 m, H8 = 2.5 m, H9 = 3.8 m, and D = 2.5 m. And the results of calculating the stability of the retaining wall that has been designed are obtained for Stability Against Overturning, namely 4.37 > 1.5 (Safe), Stability Against Shifting, namely 2.21 > 2 (Safe), and Stability Against Soil Bearing Capacity, namely 4.14 > 3 (Safe).
