Abstract
Indonesia terletak di atas 3 lempengan bumi yang memiliki potensi besar terjadinya gempa bumi. Gempa terjadi karena terlepasnya energi dari dalam bumi menyebabkan getaran hebat pada permukaan tanah dan menghancurkan bangunan-bangunan yang ada dan mengakibatkan jatuhnya banyak korban jiwa. Sebagian besar korban yang jatuh disebabkan karena ketidakmampuan bangunan untuk mengurangi dampak gempa. Terkait hal tersebut perlu adanya penelitian tentang pengembangan struktur bangunan yang ada di Indonesia.
Metode yang dapat dikembangkan dalam upaya ini adalah dengan mempelajari bagaimanakah gerakan gempa dengan mengumpulkan data-data mentah pencatatan gelombang gempa bumi. Data tersebut kemudian dikonversi menjadi data yang diolah dan untuk menghasilkan skala dan persamaan acuan.
Hasil dari penelitian ini berupa persamaan skala, konversi magnitude dan frekuensi representatif dari gempa bumi, serta karakteristik simulasi awal dari data-data yang sudah di dapatkan. Persamaan hubungan antara Magnitude dan Amplitude ini akan menjadi acuan yang digunakan untuk mensimulasikan gempa bumi pada purwarupa dengan skala ukuran alat . Dengan M untuk skala richter yang diinginkan sedangkan A untuk amplitude aktual dalam micrometer yang nantinya akan di scaling sesuai struktur dirumuskan sebagai berikut:
A=2,461x10^(-4) x M^11.23

Indonesia is located on 3 earth plates which have big risk of earthquakes. Earthquakes occur because of the release of energy from within the earth causes severe vibrations on the ground surface and destroy existing buildings and the loss of many lives. Most of the victims were caused by the inability of building to reduce the impact of the earthquake. Related to this, it needs for research on the development of existing building structures in Indonesia.
The method which can be developed in this effort is to study how the earthquake occurs by collecting raw data for recording earthquake waves. The data will be converted and processed to produce an equation and scaling reference. The equation and scaling will be used to simulate and study the characteristic of the result.
The results of this study are in the form equation and scaling, conversion of magnitude and frequency representing earthquake, as well as the characteristic of the initial simulation of the data that has been obtained. The equation of the relationship between Magnitude and Amplitude will be the reference algorithM used to simulate earthquakes on the prototype with a scaled size tool. M for expected richter scale magnitude and A for actual amplitude in micrometer which later on will be scaled down according to the simulation with equation noted as:
A=2,461x10^(-4) x M^11.23
