Abstract
Indonesia merupakan negara yang sering dilanda gempa salah satunya berasal dari aktivitas dari gunung vulkanik. Pos Pemantauan di Pasauran hanya memiliki satu sensor seismograf sebagai pengamatan. Penelitian ini bertujuan untuk membandingkan data seismograf dari pos AGK (Anak Gunung Krakatau) di Pasauran dengan sistem yang dirancang pada penelitian ini. Pemantauan kondisi AGK dengan menggunakan teknologi telemetri yaitu mengirimkan data sensor seismik dan meteorologi melalui gelombang VHF (Very High Frequency). Sensor-sensor yang digunakan adalah sensor percepatan, sensor suhu, sensor kelembaban, dan sensor tekanan udara. Sensor percepatan dikonversi menjadi skala Ritcher untuk mendapatkan pembacaan berupa seismik. Teknik modulasi yang digunakan adalah FSK (Frequency Shift Keying). Modulasi sinyal menggunakan XR2206 sebagai modulator dan XR2211 sebagai demodulator. Pengiriman data melalui gelombang VHF dapat berhasil dilakukan selama ±10 menit. Hasil perhitungan repeater pertama transmitter membutuhkan tinggi antena 30 m dan daya 20 watt sedangkan receiver membutuhkan tinggi antena 2 m dan daya 5 watt, perhitungan kedua dibutuhkan tinggi antena 100 m dan daya 30 watt untuk transmitter dan receiver

| Additional Information: | Indonesia is a country frequently hit by earthquakes, one of which is derived from the volcano activity. Monitoring Post in Pasauran have only one as observation sensor. The purpose of this research is compare data seismograph of AGK (Anak Gunung Krakatau) in Pasauran with data output which obtained from sistem designed in this study. The monitoring of AGK’s condition is done using telemetry technology which transmited data of seismic and meteorology through VHF (Very High Frequency). The sensors used in this research are acceleration sensor, temperature sensor, humidity sensor, and air pressure sensor. Output Accelerometer convert into Ritcher scale toget seismic signal. FSK (Frequency Shift Keying) is used for modulation technique. Signal modulation using XR2206 as modulator and XR2211 as demodulator. The result of data transmission is succesfully transmitted through VHF within ± 10 minutes. The result of first scenario for the transmitter requires 30 m for antenna high and 30 watt for power, while the receiver requires 2 m for antenna high and 5 watt for power. The antenna high and power required for the second scenario is 100 m and 30 watt, for both transmitter and receiver. Key Word : Anak Gunung Krak | |||||||||
