Abstract

CV. Mutiara Timur merupakan sebuah perusahaan yang sedang mengajukan izin usaha pertambangan komoditas sirtu di Desa Klampok, Kecamatan Tongas, Kabupaten Probolinggo. Sistem penambangan yang direncanakan yaitu tambang terbuka dengan metode quarry. Dari hasil penelitian dilapangan didapatkan litologi batuan berupa topsoil, kerikil dan pasir. Dimana dalam rancangan lereng nantinya, topsoil akan dikupas terlebih dahulu. Tujuan dilakukan analisis kestabilan lereng untuk menentukan geometri lereng dengan memperhitungkan faktor keamanan agar tercipta kondisi kerja yang aman. Analisis kestabilan lereng pada CV. Mutiara Timur dengan metode Bishop menggunakan bantuan software Slide v6.0. Berdasarkan analisis yang dilakukan mendapatkan rekomendasi geometri lereng pada lereng tunggal yaitu tinggi 4 meter dengan kemiringan 600 sehingga mendapatkan faktor keamanan tanpa beban sebesar 1,350 dan faktor keamanan dengan beban yaitu 1,267. Selain itu didapatkan geometri lereng pada lereng keseluruhan yaitu tinggi total 21 meter dengan kemiringan 380 sehingga mendapatkan faktor keamanan tanpa beban sebesar 1,243 dan faktor keamanan dengan beban yaitu 1,239.

Abstract

CV. Mutiara Timur is a company that is applying for a mining business permit for sirtu commodities in Klampok Village, Tongas District, Probolinggo Regency. The planned mining system is open pit mining using the quarry method. From the results of research in the field obtained rock lithology in the form of topsoil, gravel and sand. Where in the slope design later, the topsoil will be peeled off first. The purpose of slope stability analysis is to determine the geometry of the slope by taking into account the safety factor in order to create safe working conditions. Slope stability analysis on CV. Mutiara Timur using the Bishop method using the Slide v6.0 software. Based on the analysis carried out, the recommendation for slope geometry on a single slope is 4 meters high with a slope of 600 so that the no-load safety factor is 1.350 and the safety factor with load is 1.267. In addition, the slope geometry is obtained on the overall slope, which is a total height of 21 meters with a slope of 380 so that the no-load safety factor is 1.243 and the safety factor with the load is 1.239.
