Abstract

PT XYZ merupakan salah satu perusahaan yang bergerak di bidang pertambangan bauksit yang memulai kegiatan pertambangannya sejak tahun 2009. Kegiatan pengangkutan bauksit dari area penambangan ke washing plant maupun ke stockpile menggunakan rangkaian kerja alat muat dan alat angkut. Alat yang digunakan pada kegiatan pengangkutan bauksit khususnya di Pit A menggunakan 2 unit Excavator Kobelco SK330 dan 37 unit alat angkut Dump Truck Marcedez Benz Axor 2528 C dimana pengadaan alat muat dan angkut tersebut dengan skema sewa alat. Salah satu konsep dalam pengelolaan industri pertambangan adalah memperoleh keuntungan sebesar-besarnya, mengingat pentingnya hal tersebut maka perlu untuk mengetahui biaya kepemilikan dan operasional agar dapat mengendalikan biaya yang dikeluarkan perusahaan. Penelitian ini bertujuan untuk mengestimasi biaya kepemilikan (owning cost) dan biaya operasional alat (operation cost) untuk skema beli dan sewa alat menggunakan analisa Net Present Value (NPV). Berdasarkan hasil perhitungan dengan asumsi umur pakai alat lima tahun, diperoleh bahwa Nilai NPV untuk beli alat muat yaitu Rp. 16.945.147.370 dan biaya sewa sebesar Rp 30.041.150.318. Sedangkan NPV untuk skema beli alat angkut yaitu Rp 215.892.393.567 dan biaya sewa sebesar Rp 303.142.516.855. Sehingga pemilihan skema beli alat lebih menguntungkan karena biaya pengadaan alat muat dan alat angkut yang lebih rendah.

Abstract

Kondisi jalan angkut memiliki peranan penting untuk mempermudah operasi alat angkut serta dapat mengefisienkan waktu pengangkutan dalam produksi tambang bauksit di PT XXX Kabupaten Ketapang. Tanah sebagai material di jalan tambang memiliki potensi kekuatan sebagai daya pendukung untuk menahan beban kendaraan yang berada di atasnya. Pada jalan tambang, apabila kekuatan material tanah tidak lebih besar dari beban alat angkut maka dapat mengakibatkan alat angkut tidak beroperasi maksimal dan dapat menurunkan produksi penambangan bahkan dapat mengakibatkan kecelakaan kerja. Tujuan penelitan ini adalah (1) untuk mengetahui karakteristik tanah di jalan angkut tambang bauksit, (2) mengetahui persentase potensi kekuatan tanah berdasarkan uji California Bearing Ratio (CBR), serta (3) memberikan tahapan rekomendasi untuk meningkatkan kekuatan tanah di jalan angkut tambang bauksit PT XXX Kabupaten Ketapang. Metode penelitian yang digunakan adalah metode penelitian kuantitatif. Data penelitian terdiri dari data primer dan data sekunder. Data primer diperoleh dari hasil uji sifat fisik tanah dan uji CBR di laboratorium. Sedangkan data sekunder terdiri dari gambaran lokasi penelitian serta dari referensi penelitian terdahulu sebagai data pendukung untuk memperkuat analisis dan pembahasan. Hasil penelitian menunjukkan bahwa tanah di jalan angkut tambang bauksit PT XXX memiliki karakteristik yang baik secara umum sebagai tanah dasar (subgrade). Nilai persentase CBR desain paling rendah adalah sampel pertama (SA-T1) dengan nilai CBR desain sebesar 2,50% dan termasuk dalam tingkatan kelompok tanah sangat buruk (very poor). Sedangkan sampel SA-T2 dan SA-T3 yang memiliki nilai CBR desain masing-masing sebesar 14,00% dan 10,00% termasuk dalam tingkatan kelompok tanah buruk sampai cukup baik (poor to fair). Menurut kegunaannya, tiga sampel tanah tersebut dapat dijadikan sebagai lapisan tanah dasar (subgrade) di jalan angkut. Untuk meningkatkan kekuatan material tanah di jalan angkut tambang dapat dilakukan beberapa upaya perbaikan, diantaranya dengan melakukan pemadatan (compacting) dan stabilisasi tanah.

Abstract

Bauxite tailing is a by product of bauxite washing. The amount of waste from the bauxite tailings can reach about 50% of the dry weight of the bauxite before washed. The increasing demand for bauxite causes the amount of exhaust produced to be even greater. This risks causing environmental pollution problems requiring an alternative treatment and one of the solutions is utilize the bauxite tailings as a mixture of sand substitutes in the manufacture of paving blocks. The role of sand is replaced by a 50% increase in market price so that in this study a compressive strength test will be conducted on the strength of paving blocks with sand mixture (as sold in the market) with paving blocks with bauxite tailings mixed then comparison. This utilization is to minimize the environmental impacts, to reduce the accumulation of materials at the washing site, and in the future can be increasing value products that become business opportunities for affected communities due to bauxite mining. Based on the research, there is a found the average value of uniaxial compressive strength of sampel 50% : 50% is 17.19 Mpa. That is smaller than the value of uniaxial compressive strength of sampel 60% : 40%, 17.62 MPa. The meaning of compressive strength value of the sample is 60%: 40% more optimal than the sample with the ratio 50%: 50% because the value of compressive strength is included in SNI-03-0691-1996 ie on the quality of B.

Abstract

PT. XYZ merupakan salah satu perusahaan tambang bauksit yang terletak di Kecamatan Tayan Hilir Kabupaten Sanggau Kalimantan Barat. Penambangan bauksit sangat erat kaitannya dengan kegiatan pengangkutan. Dump truck memiliki dimensi yang lebih besar dibandingkan dengan kendaraan angkut di jalan raya. Alat angkut memiliki kontribusi besar terhadap total produksi. Penelitian ini bertujuan untuk menentukan produktivitas alat angkut berdasarkan grade jalan angkut tambang secara aktual, serta memberikan rekomendasi kemiringan jalan (grade) dalam upaya peningkatan produksi bauksit di perusahaan. Hasil penelitian ini nantinya akan dijadikan sebagai salah satu parameter yang dapat digunakan untuk analisis geometri jalan. Berdasarkan hasil data aktual, diketahui bahwa dari 16 segmen jalan, terdapat 3 segmen jalan yang memiliki grade belum sesuai dengan standar jalan tambang yang baik. Grade jalan masing-masing segmen adalah 10,51%; 14,05%; dan 21,26%. Produktivitas alat angkut berdasarkan data aktual dengan waktu edar 12,86 menit adalah 75.669,20 ton/bulan. Perbaikan grade jalan mengurangi waktu edar (cycle time) sebesar 0,55 menit sehingga meningkatkan produktivitas alat angkut sebesar 3.324,84 ton/bulan.Target produksi perusahaan saat ini adalah 100.000 ton/bulan, artinya target produksi perusahaan masih belum tercapai walaupun kemiringan jalan (grade) sudah sesuai standar yang telah ditetapkan. Oleh karena itu perlu adanya analisis lebih lanjut tidak hanya pada grade jalan akan tetapi juga dilakukan analisis pada keserasian alat muat-angkut serta parameter geometri jalan angkut lainnya.

Abstract

Coal is a heterogeneous, combustible material composed of various components with differing properties. The combustion process of coal in coal-fired power plants (CFPPs) generates waste in the form of bottom ash residue. If not properly utilized, bottom ash has The ability to trigger adverse environmental impacts. One alternative for its utilization is as a mixture component in the production of paving blocks. This study aims to evaluate the water absorption, compressive strength, and quality classification of paving blocks with the addition of bottom ash, where the test results will be compared with the Indonesian National Standard (SNI) to determine conformity to quality standards. According to the study, it can be seen that increasing the percentage of bottom ash leads to a higher water absorption rate and a decrease in compressive strength. This trend is attributed to the reduction in bulk density of the paving blocks as the proportion of bottom ash increases. Based on the test results, paving blocks without bottom ash (Sample A) fall into Class C; mixtures with 10% and 20% bottom ash (Samples B and C) fall into Class B; the 30% mixture (Sample D) belongs to Class C; and the 40% mixture (Sample E) is categorized as Class D. All composition variations meet the quality classification criteria stipulated in the applicable Indonesian National Standard (SNI). Based on compressive strength and water absorption parameters, the optimal bottom ash composition ranges between 10% and 20%.
