description: PT. Pamapersada Nusantara is a company engaged in mining contractors. One of the locations being worked on is coal mining owned by PT. East Kalimantan Bara Award (ABKL). The mining area is located in Kutai Kartanegara Regency, East Kalimantan Province. The mining system uses the open pit mining method and overburden demolition activities using the drilling and blasting method. One of the important factors that determine the success of a blasting operation is that in addition to obtaining good rock fragmentation according to company regulations, the ground vibration value is also in accordance with SNI7571:2010 concerning Quality Standards for Blasting Vibration Levels in Buildings. The problem in question is that the blasting results have not produced a ground vibration according to PERMEN ESDM 7571:2010. The purpose of this study was to determine the factors that affect the geround vibration of blasting results. And looking for improvement ideas for these problems with the target according to the ground vibration value below the threshold of the highest value of SNI7571:2010, namely with a class 2 building with the highest ground vibration value of 3 mm/s. The methods used in this research are as follows: Literature study, field observations, data collection in the form of primary and secondary data, data processing and analysis techniques, and conclusions. The results showed that by using the spot decking method which aims to increase the explosive charge without adding explosives while reducing the stemming height, it is proven that at critical locations/substandard locations, tinulu can reduce the ground vibration value according to SNI75712020 by 31% without reducing the filling. actual explosives.

Pamapersada Nusantara merupakan perusahaan yang bergerak dalam bidang kontraktor pertambangan. Salah satu lokasi yang di kerjakan yakni penambangan batubara milik PT. Anugerah Bara Kaltim (ABKL). Lokasi daerah penambangan terletak di Kabupaten Kutai Kartanegara, Provinsi Kalimantan Timur. Sistem penambangan menggunakan metode tambang terbuka dan kegiatan pembongkaran overburden dengan metode pengeboran dan peledakan. Salah satu faktor penting yang menentukan keberhasilan suatu operasi peledakan adalah selain mendapatkan fragmentasi batuan yang baik sesuai ketentuan perusahaan juga nilai ground vibration sesuai dengan SNI7571:2010 Tentang Baku Mutu Tingkat Getaran Peledakan Pada Bangunan. Masalah yang bersangkutan yaitu hasil peledakan belum mengahsilkan ground vibration sesuai PERMEN ESDM 7571:2010. Tujuan dari penelitian ini adalah untuk mendapatkan faktor-faktor yang mempengaruhi geround vibration hasil peledakan. Serta mencari ide perbaikan untuk permasalahan tersebut dengan sasaran sesuai nilai ground vibration dibawah ambang batas nilai tertinggi SNI7571:2010 yaitu dengan bangunan kelas 2 dengan nilai ground vibration tertinggi yaitu 3 mm/s. Adapun metode yang digunakan dalam penelitian iniadalah sebagai berikut: Studi literatur, pengamatan dilapangan, pengambilan databerupa data primer dan data sekunder, teknik pengolahan dan analisa data, sertakesimpulan. Hasil penelitian menunjukkan bahwa dengan menggunakan metode spot deking yang bertujuan untuk menaikkan isian bahan peledak tanpa menambah bahan peledak sekaligus mengurangi tinggi stemming terbukti pada lokasi kritikal/lokasi supstandar  tinulu dapat menurunkan nilai getaran tanah (ground vibration) sesuai dengan SNI75712020 sebesar 31% tanpa mengurangi isian bahan peledak aktual.
