“…Various slope protection methods were proposed for this sedimentary rock site, including shotcrete, wire mesh, net rock bolting, and targeted rock removal. Implementing a drainage system with proper gradient, asphalt layer application, and biotechnical slope protection were also suggested strategies [18,19,20]. These measures aimed to mitigate potential slope hazards and improve stability.…”

A study was conducted along the Jantho-Lamno road to identify and mitigate landslide risks by analyzing the relationship between seismic wave propagation velocity and rock resistivity. The research aimed to assess geological conditions and pinpoint areas prone to slope failure, employing both seismic and resistivity methods on three selected lines (L1, L2, L3). Seismic wave propagation velocity (Vp) and resistivity (ρ) values were analyzed using ZondST2D and Res2Dinv software. The results revealed a distinct weak zone characterized by contrasting layers: a soft first layer and a denser second layer. Within this zone, Vp ranged from 0.3 to 0.9 km/s, with resistivity measuring less than 10 Ωm, mainly comprising sandstone and clay. This weak zone acted as a slip plane, driven by a water-saturated layer's pushing force, making it susceptible to structural instability due to gravitational pressure. To mitigate land creep, the proposed strategy involved constructing retaining walls, piles, shotcrete, wire mesh, net rock bolting, and rock removal techniques, tailored to the geological conditions of L2 and L3 Jantho. Similar measures would be implemented at L1 Lamno. L1 Lamno was identified as an ideal location for studying slope stability mitigation measures. Landslides in Aceh Province result from factors such as active tectonic movements, intense rainfall, geological structures, weathering processes, and seismic activity. Implementing slope stabilization and protection methods effectively reduces landslide risks, benefiting the region's safety and infrastructure.

“…Previous research has been conducted by Rusydy et al (2021), which analyzed the stability of rock and soil slopes in tropical and tectonically active areas. The correlation results between SPT data and geophysical survey data are used in slope stability analysis and provide information about areas vulnerable to landslides triggered by earthquakes and other geological threats [7]. Marques et al (2017) conducted a slope stability study on a highway near Guarulhos City, Brazil.…”

Landslide events cause road access to be cut off, such as in the Payung area of Batu City, which connects Malang and Kediri. Analysis and evaluation of landslide disasters need to be carried out in this area to anticipate the next landslides and reduce economic losses. This study aims to determine landslide potential in the Payung Area, Batu City, using the SPT method. The test is carried out at 2 points of the slope on the provincial roads and the slope above the road so that the two measurement points can be correlated. The data needed to analyze slope stability include the internal shear angle, cohesion, and soil unit weight; analysis and modeling of slope stability using Geostudio SLOPE/W software. The results of the slope stability analysis at point 1 show that the average failure line is at a depth of 6.00 m with the smallest Safety Factor (SF) value of 0.710 in scenario 2. While the slope at point 2, the failure line is at a depth of 1.50 m with the smallest FK value of 0.840 in scenario 2. Significant changes in the N-SPT value indicate differences in soil mechanical properties, such as shear angle and cohesion that affect the stability of the slope and cause landslides.
