Kajian Pengaruh Arah Umum Struktur Geologi Terhadap Getaran Tanah pada Peledakan Penambangan Quarry Batu Granit PT. Pacific Granitama

Abstract. This thesis is a research on the influence of the general direction of geological structures on ground vibration caused by blasting activities. Based on KEPMEN ESDM No. 1827 K/30/MEM/2018, mining companies are required to monitor ground vibration to ensure that the level of ground vibration does not exceed the threshold. The presence of geological structures can be an influence variable of the resulting ground vibration, so it is necessary to study the general direction of the structure to design the optimal implementation of blasting activities. Determination of the general direction of the structure and rock mass was carried out using the scanline and rock mass rating methods. Data collection techniques were carried out by field observation to determine the general direction of the structure and blasting geometry design. The analysis was conducted using the Scaled Distance Law to predict the Peak Particle Velocity value where the threshold value set by SNI 7571 Year 2023 in the second class (II) building is 3.00 mm/s. The results showed the peak vector sum (PVS) value ranged from 0.683 - 4.463 mm/s. The general direction of the structure stretches by N292OE with the direction of Northwest - Southeast orienetation, with a rock mass rating (RMR) value of 81 which is included in the good rock class. The vibration prediction value obtained ranges from 0.62 - 1.3 mm/s. Therefore, the PVS prediction value is still below the specified threshold. Abstrak. Skripsi ini merupakan penelitian mengenai pengaruh arah umum struktur geologi terhadap getaran tanah yang diakibatkan karena adanya aktivitas peledakan. Berdasarkan KEPMEN ESDM No. 1827 K/30/MEM/2018, perusahaan pertambangan wajib melakukan monitoring getaran tanah untuk memastikan bahwa tingkat getaran tanah tidak melebihi ambang batas. Keterdapatan struktur geologi dapat menjadi variabel pengaruh dari getaran tanah yang dihasilkan sehingga diperlukan adanya kajian tentang arah umum struktur untuk merancang pelaksanaan kegiatan peledakan yang optimal. Penentuan kondisi arah umum struktur dan massa batuan dilakukan dengan menggunakan metode scanline dan rock mass rating. Teknik pengambilan data dilakukan dengan observasi lapangan untuk mengetahui keadaan arah umum struktur dan rancangan geometri peledakan.

Hasil penelitian menunjukan nilai peak vector sum (PVS) berkisar antara 0,683 – 4,463 mm/s. Arah umum struktur membentang sebesar N292OE dengan arah orienetasi Barat Laut – Tenggara, dengan nilai rock mass rating (RMR) sebesar 81 yang termasuk dalam kelas good rock. Nilai prediksi getaran yang didapat berkisar antara 0,62 – 1,3 mm/s. Maka dari itu nilai prediksi PVS masih di bawah ambang batas yang ditentukan.
