Abstract


PT. Niat Karya adalah perusahaan swasta yang bergerak di bidang penyediaan jasa penambangan, pengolahan, dan pengaspalan jalan raya yang didirikan pada bulan Juni 2016 di Desa Sabedo Kecamatan Utan Kabupaten Sumbawa. Hasil penambangan terdiri dari sirtu dan kerokol dengan menggunakan sistem tambang terbuka dengan metode Quarry Mine. Material Hasil penambangan pada Quarry di angkut ke stoke pile untuk di tampung kemudian di bawa ke Crushing Plant untuk di olah menggunakan alat Stone Crusher yang berkapasitas 20 m3/jam. Proses pemecahannya melalui 2 (dua) tahapan antara lain: 1) Primary Crusher, dalam tahapan ini material akan di pecahkan menggunakan alat jaw crusher hingga berukuran 70 mm; 2) Secondary Crusher, Dalam tahapan ini material akan di pecahkan menggunakan impact mill hingga berukuran < 70 mm. Batuan yang telah di pecahkan akan diayak menggunakan vibrating screen. Proses screening menghasilkan 3 (tiga) ukuran produk berupa agregat Material Beton (20 – 36 mm), Coarse Agregat (9 – 20 mm), dan Fine Agregat (-9 mm).
