Abstract

Pengambilan data sampling vessel menggunakan Terestrial Laser Scanner (TLS) dapat dilakukan dengan cepat, jika dibandingkan dengan alat ukur lainnya, Terestrial Laser Scanner (TLS) memiliki tingkat akurasi yang lebih tinggi serta waktu pengoperasian yang lebih efektif dan efisien. Kegiatan penambangan memerlukan perhitungan volume sampling vessel setelah dilakukan pengangkutan overburden ke area disposal, sampling vessel dilakukan setiap seminggu sekali untuk memastikan volume overburden yang diangkut oleh Heavy Duty (HD) sesuai dengan kapasitas muatan. Penelitian ini bertujuan untuk membandingkan kemampuan Surpac dan AutoCAD Civil 3D dalam melakukan perhitungan volume sampling vessel dengan menggunakan metode Borrow Pit, Kontur, dan Cross Section yang berada di area tambang PT. Pamapersada Nusantara. Analisis dilakukan dengan menghitung persentase perhitungan volume yang paling rendah pada masing-masing metode dan software terhadap hasil perhitungan truck count atau kapasitan muatan setiap Heavy Duty (HD) untuk mendapatkan volume yang paling optimal dan dekat dengan nilai acuan. Hasil penelitian menunjukkan bahwa nilai persentase selisih perhitungan volume paling rendah adalah pada perhitungan metode Kontur dengan interval contour 0,15 pada software Surpac, yaitu sebesar 32,64%, yang artinya muatan Heavy Duty (HD) melebihi 32,64% dari truck count. Metode Kontur pada software Surpac memiliki nilai persentase volume paling kecil. Hal ini, disebabkan metode Kontur lebih cocok digunakan untuk menghitung timbunan berupa gundukan, sedangkan software Surpac memang telah dibuat khusus untuk keperluan penunjang pengolahan data pertambangan.

Collecting vessel sampling data using a Terrestrial Laser Scanner (TLS) can be done quickly, when compared to other measuring instruments, the Terrestrial Laser Scanner (TLS) has a higher level of accuracy and more effective and efficient operating time. Mining activities require calculating the volume of sampling vessels after transporting overburden to the disposal area. Sampling vessels are carried out once a week to ensure that the volume of overburden transported by Heavy Duty (HD) matches the load capacity. This research aims to compare the capabilities of Surpac and AutoCAD Civil 3D in calculating the volume of sampling vessels using the Borrow Pit, Contour and Cross Section methods in the mine area PT. Pamapersada Nusantara. The analysis is carried out by calculating the percentage of the lowest volume calculation for each method and software against the truck count or load capacity calculation results for each Heavy Duty (HD) to obtain the most optimal volume and close to the reference value. The results of the research show that the lowest percentage value of the volume calculation difference is in the Contour method calculation with a contour interval of 0.15 in the software Surpac, which is 32.64%, which means the Heavy Duty (HD) load exceeds 32.64% of the truck count. The Contour method in the software Surpac has the smallest volume percentage value. This is because the Kontur method is more suitable for calculating piles in the form of mounds, whereas the software Surpac has been specifically created to support mining data processing.
