Abstract
Jalan Mulia-Sinak merupakan jalur strategis yang dibangun dengan tujuan pemerataan pembangunan di wilayah Provinsi Papua Pegunungan. Meski demikian dalam pembangunannya terdapat banyak tantangan, salah satunya masalah
ketidakstabilan lereng (Longsor) pada STA 4+350. Salah satu faktor penyebab kelongsoran di daerah Kabupaten Puncak adalah pelapukan batuan yang disebabkan oleh lereng yang terekspos siklus pembasahan-pengeringan. Penelitian
ini bertujuan untuk menganalisis proses pelapukan melalui pengamatan pada perubahan rasio disintegritas dan solusi perkuatan pada lereng batuan terlapuk.
Pada penelitian ini akan dilakukan 15 Siklus pembasahan-pengeringan, yang terdiri dari pembasahan selama 15 jam dan pengeringan selama 12 jam dalam 1 siklus. Pengujian akan dilakukan tiap 5 siklus yaitu pada siklus ke-0 (initial), ke-5, ke-10 dan ke-15. Setelah mengalami 5 siklus pembasahan-pengeringan, nilai DR turun dengan masif menjadi 0.52 atau turun sebesar 48%. Nilai DR kemudian kembali turun sebesar 7.69% menjadi 0.48 pada siklus ke 10 dan akhirnya turun menjadi 0.45 atau turun sebesar 6.25% pada siklus ke 15. Berdasarkan hasil pemodelan lereng, diketahui bahwa Nilai SF lereng turun setelah diberikan pengaruh pembasahan-pengeringan, dimana nilai SF menjadi 0.435 untuk kondisi 5 siklus, 0.331 untuk kondisi 10 siklus dan 0.324 untuk kondisi 15 siklus. Setelah diberikan perkuatan, terjadi peningkatan nilai SF menjadi 1.595.

The Mulia-Sinak Road is a strategic route built with the aim of equitable development in the Papua Pegunungan Province. However, its construction faced many challenges, one of which was slope instability (landslides) at STA 4+350. One of the factors causing landslides in the Puncak Regency area is rock weathering caused by slopes exposed to wetting-drying cycles. This study aims to analyze the weathering process through observations of changes in the disintegration ratio and reinforcement solutions on weathered rock slopes. In this study, 15 wetting-drying cycles will be conducted, where one cycle consists of wetting for 15 hours and drying for 12 hours. Testing will be carried out every 5 cycles, namely on the 0th (initial), 5th, 10th and 15th cycles. After experiencing 5 wetting-drying cycles, the DR value dropped massively to 0.52 or a decrease of 48%. The DR value then decreased again by 7.69% to 0.48 in the 10th cycle and finally decreased to 0.45 or decreased by 6.25% in the 15th cycle. Based on the results of slope modeling, it is known that the SF value decreased after being given the effect of wetting-drying, where the SF value became 0.435 for the 5 cycle condition, 0.331 for the 10 cycle condition and 0.324 for the 15 cycle condition. After the slope reinforcement was planned, the SF value increased to 1.595.
