“…Sedangkan keruntuhan lereng yang disebabkan oleh manusia misalnya terjadi akibat adanya penggalian pada lereng (Hamdan dan Pratiwi, 2017). Bencana keruntuhan lereng ini dapat diminimalisir dengan cara dilakukan penanaman dengan tanaman atau pepohonan sehingga lereng akan lebih tahan terhadap erosi akibat adanya perkuatan lereng secara alami berupa adanya akar-akar tanaman dan pohon yang tumbuh (Razali et al, 2023). Hal ini tentu akan meningkatkan kestabilan lereng sehingga tidak mudah untuk runtuh.…”

Lereng merupakan permukaan tanah yang memiliki beda tinggi. Ketidakstabilan lereng menyebabkan bencana keruntuhan yang menyebabkan kerugian secara materil maupun korban jiwa. Pada lereng Sungai Aceh Tamiang, Kampung Rantau Pakam, Provinsi Aceh sering terjadi bencana keruntuhan sehingga perlu dilakukan penelitian terhadap stabilitas lereng. Penelitian bertujuan mengetahui nilai faktor keamanan lereng dan meningkatkan nilai stabilitas lereng sungai dengan perkuatan lereng. Metode analisis menggunakan metode Bishop untuk perhitungan secara manual dan Metode Elemen Hingga menggunakan bantuan software Plaxis 2D. Jenis perkuatan stabilitas lereng menggunakan soil nailing dan dinding MSE. Hasil penelitian menunjukkan nilai faktor keamanan lereng eksisting tidak memenuhi persyaratan minimum kestabilan lereng maka perlu perkuatan lereng. Hasil perhitungan faktor keamanan stabilitas lereng dengan perkuatan soil nailing sebesar 1,335 lebih kecil dari persyaratan sebesar 1,5. Faktor keamanan stabilitas lereng dengan perkuatan dinding MSE sebesar 1,457 lebih besar dari persyaratan sebesar 1,3. Hasil analisis menunjukkan bahwa metode MSE lebih sesuai digunakan untuk perkuatan lereng.

Introduction Landslides frequently occur along roads crossing mountainous terrain during the rainy season, posing a significant risk of severe disruption to land transportation routes. Efficient and accurate resolutions are essential in managing landslides to facilitate immediate transportation recovery, such as gabion walls and pile installation. Aim This article aimed to evaluate the effect of installing gabions and piles for safety measures on the stability of slope landslides. The analysis of slope stability was performed utilizing the Plaxis 2D software. For reinforced slopes, the Safety Factor (SF) value utilized as a benchmark for evaluating slope stability was SF ≥ 1.5. Methods An assessment of the stability of the slope was conducted under three conditions: its original state, after reinforcement with gabions, and after the integration of gabions with mini piles. The dimensions of the gabion setting, as determined by the L-W-H notation (length-width- height), were 2 m x 1m x 0.5 m and 1 m x 2 m x 0.5 m. The pile was designed to be 2.5 m long at the gabion's end. The analysis was conducted at 45°, 60°, 70°, and 90° slopes. Results Based on the results of slope stability calculations, an SF = 1.11 was determined under no reinforcement conditions. By applying reinforced gabion walls measuring 2 m in width combined with mini piles at a 45° slope, the best SF was achieved, which was 2.58. Conclusion Given the comparable topographical circumstances, it is expected that the outcomes of this analysis on slope stability will be applicable in mitigating the occurrence of landslides.
