Abstract: . PT Indocement Tunggal Prakarsa Tbk (ITP) is a company that produces cement, ready-mix concrete, manages aggregate and tras quarries. This study examines the impact of blasting vibrations in the area of block 2 quarry D PT ITP Citeureup, the distance to the settlement is only ± 421.43m from the mining location. The study aims to analyze the magnitude of vibrations due to blasting, vibration levels based on SNI 7571: 2023, identify factors that influence the level of ground vibration. Data were collected using micromate and analyzed multivariately to determine the relationship of PPV to SD, the amount of explosives, and distance. The analysis of vibration levels was carried out using several approaches, namely by using regression analysis models, log square root, and empirical methods (USBM, Langefors & Kiehlstrom, Indian Standard, Ambreaseye Hedron). Each analysis model produces different k and e value equations, thus producing different predicted PPVs as well. Data processing shows the PPV value of transverse measurement results of 0.118-0.441mm/s, vertical 0.087-0.402mm/s, and longitudinal 0.095-0.378mm/s. Based on the PPV processing, the prediction is 0.194-0.709mm/s, the results of the study indicate that the value of ground vibration in the blasting area is below the threshold. Abstrak. PT Indocement Tunggal Prakarsa tbk (ITP) merupakan perusahaan yang memprodukasi semen, beton siap pakai, mengelola tambang agregat dan tras. Penelitian ini mengkaji dampak getaran peledakan diarea blok 2 kuari D PT ITP Citeureup, jarak kepemukiman hanya ±421,43m dari lokasi penambangan. Penelitian bertujuan untuk menganalisis besarnya getaran akibat peledakan, tingkat getaran berdasarkan SNI 7571:2023, mengidentifikasi faktor yang mempengaruhi tingkat getaran tanah. Data dikumpulkan menggunakan micromate dan dianalisis secara multivariat untuk menentukan hubungan PPV terhadap SD, jumlah bahan peledak, dan jarak. Analisis tingkat getaran dilakukan menggunakan beberapa pendekatan, yaitu dengan menggunakan model analisis regresi, log square root, serta metode empiris (USBM, Langefors & Kiehlstrom, Indian Standard, Ambreaseye Hedron). Setiap model analisis menghasilkan persamaan nilai k dan e yang berbeda, sehingga menghasilkan PPV prediksi berbeda juga. Pengolahan data menunjukkan nilai PPV hasil pengukuran transversal 0,118-0,441mm/s, vertikal 0,087-0,402mm/s, dan longitudinal 0,095-0,378mm/s. Berdasarkan pengolahan PPV Prediksi didapatkan 0,194-0,709mm/s, hasil penelitian menunjukkan nilai getaran tanah diarea peledakan berada dibawah ambang batas.
