Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)
It has been realized, a telemetry of vibration system using an accelerometer MMA7361 that based on microcontroller ATMega8535 with handy talky (HT) as transmission medium. The main purpose of the research was to make a simple earthquake detection system. The system consists of an accelerometer MMA7361, microcontroller ATMega8535, a pair of FSK TCM3105 modulator demodulator, HT as a transmitter and receiver, LCD and a PC. Research tested by put the accelerometer sensor on top of speakers witch given some frequencies from signal generator, which is regarded as the artificial earthquake vibrations. Vibration data automatically captured by microcontroller master, then the output signal was modulated by TCM3105, so that the signal can be send with HT transmitter. Data that received by HT receiver is demodulated before entering the microcontroller slave, then the output signal went to PC. The results of the research obtained an deviation standart of data delivery on the telemetry system was equal to 0,2313 V on the X-axis, the Y-axis is equal to 0,4954 V and 0,0198 V of the Z-axis. Telah direalisasikan sistem telemetri getaran dengan media transmisi HT menggunakan sensor accelerometer MMA7361 berbasis mikrokontroler ATMega8535. Tujuan penelitian adalah membuat sistem pendeteksi gempa bumi sederhana. Sistem ini terdiri atas sensor accelerometer, mikrokontroler, modem FSK TCM3105, sepasang HT sebagai transmitter dan receiver, LCD dan PC. Penelitian dilakukan dengan meletakan sensor accelerometer di atas speaker yang diberikan frekuensi dari signal generator, dianggap sebagai getaran gempa bumi buatan. Data getaran sensor secara otomatis diambil oleh mikrokontroler master, lalu sinyal keluarannya dimodulasi dengan modul FSK untuk dikirim dengan HT transmitter. Data yang diterima HT receiver didemodulasi sebelum masuk ke mikrokontroler penerima lalu ke PC. Data hasil penelitian dianalisis dan diperoleh standar deviasi rata-rata dari pengiriman data pada sistem telemetri adalah sebesar 0,2313 V pada sumbu X, untuk sumbu Y sebesar 0,4954 V dan pada sumbu Z sebesar 0,0198 V.
