Abstract
Getaran kejut merupakan getaran yang terjadi dalam waktu yang singkat dan memiliki amplitudo yang sangat tinggi dan frekuensi yang cepat. Getaran dapat menimbulkan dampak negatif bagi kualitas hidup manusia di sekitarnya. Dampak yang ditimbulkan yaitu kenyamanan yang langsung dirasakan manusia dan kerusakan fisik pada bangunan bisa berakibat robohnya bangunan. Seismik adalah gelombang elastik yang merambat dalam bumi. Seismik bisa disebabkan oleh kegiatan manusia seperti kegiatan kontruksi ataupun kendaraan yang melintas di dekat bangunan, bisa dirasakan langsung gertarannya dan juga peristiwa alam mempengaruhi Seismik seperti gempa bumi. Getaran pada bangunan yang ditimbulkan dari seismik berkaitan dengan ground vibration. Hubungan tersebut ditunjukkan oleh konsep Peak Particle velocity (PPV). Menteri Negara Lingkungan Hidup menerbitkan Keputusan Nomor KEP-49/MENLH/11/1996 menenapkan kecepatan getaran maksimal berdasarkan jenis bangunan. Alat pengukur getaran bangunan sudah banyak dikomersilkan tetapi sulit untuk dioperasikan oleh orang awam dan tidak dilengkapi dengan alarm sebagai sistem peringatan dini. Maka dari itu tujuan alat ini dirancang agar masyarakat dapat mengetahui adanya getaran pada bangunan secara langsung. Alat ini dilengkapi LCD TFT yang akan menunjukan hasil pengukuran getaran bangunan berupa Peak Particle velocity dengan parameter mm/s serta buzzer yang akan menyala jika getaran melebihi batas maksimal yang ditetapkan. Alat ini menggunakan sensor geophone untuk mendeteksi getaran dengan akurasi sensor arah vertikal ± 95,08 %, arah Horizontal W-E ± 95,12 %, arah Horizontal S-N ± 96,04

Shock vibrations are vibrations that occur in a short time and have a very high amplitude and fast frequency. The impact is that the comfort that is directly felt by humans
and physical damage to buildings can result in the collapse of the building. Seismic is an elastic wave that propagates in the earth. Seismic can be caused by human activities such as construction activities or vehicles passing near buildings, the vibrations can be felt directly and also natural events that affect seismic such as earthquakes. Vibration in buildings caused by seismic related to ground vibration. This relationship is shown by the concept of Peak Particle velocity (PPV). The State Minister for the environment issued Decree Number KEP49/MENLH/11/1996 stipulating the maximum vibration speed based on the type of building. Building vibration measurement devices have been widely commercialized but are difficult to operate by ordinary people and are not equipped with an alarm as an early warning system. Therefore the purpose of this tool is designed so that people can find out the presence of vibrations in buildings directly. This tool is equipped with a TFT LCD that will show the results of measuring building vibrations in the form of Peak Particle velocity with mm/s parameters and a buzzer that will light up if the vibration exceeds the set maximum limit. This tool uses a geophone sensor to detect vibrations with an accuracy of the vertical direction sensor ± 95.08%, the W-E Horizontal direction ± 95.12%, the Horizontal S-N direction ± 96.04
