Abstract

PT X had an accident  of slope failure that caused fatalities and injuries experienced by labor mining, and also some heavy mining equipments  buried  by  materials  that causing companies got financial loss. therefore important to analyze the slope stability of surface mining operation, and predicting total volume of slope failure to anticipate the impact of fatalities/ injuries and financial risks. This research  aim is  to analyze  slope stability before failure conditions, predicting volume of slope failure, and determine position of critical zone using limit equilibrium “Simpilfied Bishop” method 3-dimensional, then doing validation with calculation of actual volume by comparing results of topography maps before and after failure using the cut and fill method. From the result of research, the slope on unstability conditions, actual and predicted volume of  slope failure is  8,629 m3 and 10,559 m3, so percent of calculation error is 18.3% .

Abstract

 Perkembangan penerapan metode statistika dalam analisis kemantapan lereng tambang di Indonesia sudah berjalan secara cukup lengkap lebih dari 1 dekade. Penerapan tersebut ditujukan untuk  mengatasi variasi parameter pembentuk lereng maupun beban pada lereng. Tulisan ini mengulas mengenai penerapan metode statistika dalam analisis analisis kemantapan lereng di Indonesia, yang diawali dengan penentuan fungsi distribusi dan penerapannya dalam analisis kemantapan lereng, perhitungan FK dan PK, serta pengembangan kurva kestabilan lereng ABSTRACT Abstract should be written of maximum 200 words in 1 (one) alinea or paragraph, in English, in italics with Arial Narrow  points-9 within 1 space of each line.  Content of the Abstract should be clear, descriptive, providing a brief overview of the problem studied. including purpose, method of the research, brief overview

Abstract

PT Freeport Indonesia (PTFI) adalah perusahaan pertambangan yang beroperasi di daerah terpencil Pegunungan Jayawijaya Papua, dan berjarak sekitar 3.500 km sebelah timur Jakarta, Indonesia.Cakupan area operasi penambangan yang terbentang dari dataran tinggi hingga dataran rendah berkaitan erat dengan kondisi jalan dan perubahan cuaca yang ekstrim. Selain tantangan alam tersebut, perilaku pengemudi kendaraan ringan yang tidak aman juga menjadi salah satu faktor penyumbang yang signifikan terhadap risiko terjadinya kecelakaan kendaraan ringan. Penerapan program teknologi pemantauan kendaraan ringan merupakan salah satu program keselamatan kerja di PTFI dengan tujuan untuk meningkatkan kesadaran berkendaraan sekaligus mendorong perubahan perilaku yang aman. Tulisan ini menjelaskan latar belakang, penerapan, tantangan yang dihadapi, hasil, dan potensi perbaikan di masa mendatang dari program ini untuk memastikan keselamatan pekerja di daerah operasi PTFI.
