Abstract

ABSTRACT THE PROTOTYPE DESIGN OF EARTHQUAKE MONITORING SYSTEM USING INERTIAL MEASUREMENT UNIT (IMU) SENSOR AND THE UTILIZATION OF FREQUENCY SHIFT KEYING (FSK) METHOD VIA HANDY TALKY (HT) FREQUENCY By : KEVAN DHARMA 0810452020 Indonesia is lying among the Ring of Fire area which has high potential in natural disasters. Some of data from BMKG (Bada Meteorologi, Klimatologi dan Geofisika) indicates that the earthquake activity in Indonesia is very active. The major earthquake in 30th September 2009 in west Sumatra causing the electricity and communication cut off, so people difficult to access the information about the possibility of further earthquakes. One of communication tool which can be active without connected to electricity is Handy Talky. Handy Talky is used as a transmission media of vibration data and swing data of IMU sensor (Inertial Measurement Unit) from transmitter to receiver from point-to-point. Therefore, is made a prototype for earthquake monitoring via Handy Talky communication using FSK (Frequency Shift Keying) method. FSK method is used because the amplitude is stable and the frequency can be changed so it is invulnerable to noise. From the result of the test, conclude that Handy Talky can be communicate in half-duflex about 3.5 km while transmission data in real time and efficient limited in 2.5km.
