Abstract

PT. Ricopec Indonesia is a production operation mining permit (IUP) company which is
engaged in the business of mining bauxite ore. PT. Ricopec Indonesia is included in the Meliau District,
Sanggau Regency, West Kalimantan Province. Mining activities implemented by PT. Ricopec is a surface
mine.
Bauxite ore mining activities are carried out using open pit and open cut methods, open pit
mining is carried out from a relatively flat surface downward following the ore deposit, while open cut is
carried out on the slopes of a hill, so the application of open pit and open cut depends on the location and
shape of the deposit. Bauxite ore to be mined. The purpose of this research is to determine the real or
actual production of loading and unloading equipment and transportation equipment in bauxite ore
mining activities and to find out the causes of not achieving the production of loading and unloading
equipment and transportation equipment. Bauxite ore mining activities at PT. Ricopec Indonesia uses a
combination of 1 Komatsu PC 200 LC-8 excavator with 6 Hino FM 260 JD dump trucks. The set
production target is 100,000 tons/month. The actual production obtained on the Komatsu PC 200 LC-8
fleet is 73,767 tons/month where the current production target has not been achieved.
Efforts to increase production targets are carried out by improving the cycle time of loading and
unloading equipment and transportation equipment, and improving work efficiency. As for the calculation
after making repairs, the productivity of repairs obtained on the Komatsu PC 200 LC-8 fleet is 93,030
tons/month. Thus, the set production target can be achieved = PT. Ricopec Indonesia merupakan perusahaan pemegang izin usaha pertambangan (IUP) operasi
produksi yang bergerak dalam bidang usaha pertambangan bijih bauksit. PT. Ricopec Indonesia ini
termasuk dalam wilayah Kecamatan Meliau, Kabupaten Sanggau, Provinsi Kalimantan Barat. Kegiatan
penambangan yang diterapkan PT. Ricopec adalah tambang terbuka (surface mine).
Kegiatan penambangan bijih bauksit dilakukan dengan menggunakan metode open pit dan open cut,
penambangan open pit dilakukan dari permukaan yang relatif mendatar kebawah mengikuti endapan biji,
sedangkan open cut dilakukan pada lereng suatu bukit, jadi penerapan open pit dan open cut tergantung
pada letak dan bentuk endapan bijih bauksit yang akan ditambang.
Tujuan dilakukan penelitian ini adalah untuk mengetahui produksi nyata atau aktual dari alat gali muat
dan alat angkut pada kegiatan penambangan bijih bauksit dan mengetahui penyebab tidak tercapainya
produksi alat gali muat dan alat angkut. Kegiatan penambangan bijih bauksit di PT. Ricopec Indonesia
menggunakan kombinasi 1 unit excavator Komatsu PC 200 LC-8 dengan 6 unit dump truck Hino FM 260
JD. Target produksi yang ditetapkan adalah 100.000 ton/bulan. Produksi nyata yang didapatkan pada fleet
Komatsu PC 200 LC-8 sebesar 73.767 ton/bulan dimana target produksi saat ini belum tercapai.
Upaya peningkatan target produksi dilakukan dengan cara perbaikan cycle time alat gali muat
dan alat angkut, dan memperbaiki efisiensi kerja. Adapun perhitungan setelah melakukan perbaikan,
produktivitas perbaikan yang didapatkan pada fleet Komatsu PC 200 LC-8 sebesar 93.030 ton/bulan.
Dengan demikian maka target produksi yang ditetapkan dapat tercapai.
