Abstract
Penerapan blasting system di PT.NNT bertujuan untuk mensinergikan
kegiatan peledakan kedalam program dispatch. Dispatch blasting system
mempunyai tiga kegunaan yang paling utama antara lain collector (pengumpul
data), controll & monitoring dan database. Seluruh data pelaporan kegiatan
peledakan dapat diakses secara langsung ataupun tidak langsung melalui intranet
atau internet. Alat – alat yang digunakan dalam dispatch blasting system antara
lain komputer pusat (host computer), komputer lapangan (field equipment),
wireless dan GPS (Global Positioning System). Keunggulan dispatch blasting
system terdapat pada GPS dan wireless. GPS berfungsi untuk menampilkan pada
layar posisi truck MMU yang sedang beroperasi di pit, sedangkan wireless
berfungsi untuk menjalin komunikasi antara komputer pusat dengan komputer
lapangan.
Penerapan blasting system terbukti dapat meningkatkan efektifitas dan
efisiensi delivery system bahan peledak tanpa mengurangi safety operator truck
mobile manufacturing/mixing unit (truck MMU). Blasting system spesifik
terhadap kedalaman lubang ledak dan jumlah bahan peledak yang digunakan. Di
PT. NNT Jumlah bahan peledak yang digunakan mengacu pada nilai powder
factor berdasarkan cookbook. Nilai powder factor pada cookbook diperoleh dari
perbandingan jumlah bahan peledak dengan tonase batuan yang diharapkan
terbongkar. Di lokasi penelitian masih ditemukan penyimpangan dalam
pemanfaatan blasting system, hal ini dibuktikan dengan perbedaan jumlah bahan
peledak yang digunakan berdarkan plan blast pattern.

ABSTRACT
The study was conducted at PT. Newmont Nusa Tenggara (PT. NNT)
located in Sejorong, District Jereweh, West Sumbawa, West Nusa Tenggara
province from June to September 2012.
Implementation blasting system in PT. NNT aims to synergize the
activities of blasting into the dispatch program. Dispatch blasting system has three
primary uses include collector (collecting data), controll and monitoring and
database. All data reporting blasting activities can be accessed directly or
indirectly via intranet or internet. Equipments used in dispatch blasting system
including a central computer (host computer), computer field (field equipment),
wireless and GPS (Global Posiotionig System). Advantage of dispatch blasting
system found on GPS and wireless. GPS function is to display on-screen position
MMU trucks operating in the pit, and wireless function is to display establish
communication between the central computer to the computer field.
Implementation blasting system is provern can increase the effectiveness
and efficiency of the delivery system without compromising safety of MMU truck
operator. Blasting system specific to explosive hole depth and total explosive
used. At PT. NNT number of explosive used refers to the value of powder factor
based on the cookbook. Powder factor in the cookbook value obtained from the
comparison of total explosive with the expected tonnage of rock exposed. In the
study founded that irregularities in the use of blasting system, this is evidenced by
the difference in the total explosive used based on blast pattern plan.
