Abstract

Indonesia is prone to natural disasters due to its location at the confluence of active tectonic plates, active mountain ranges and tropical climate. One of the most common natural disasters is earthquakes, which can cause serious damage and even threaten human lives. Although there have been efforts to develop earthquake early warning systems, further innovation is still needed. Accelerometer sensors are used to detect ground movement that has output in the form of X, Y, and Z coordinate values. Vibration sensors are used to determine the amount of vibration that vibrates on the ground which has a voltage output. The purpose of this research is to provide early warning to the public against earthquakes through earthquake detection alarms. So that the results obtained are in accordance with the formulation that has been made. This system gives a warning when an earthquake occurs in the form of a sound issued by a buzzer. Then connected with NodeMCU ESP8266, so that it is able to send the magnitude of the earthquake in units of the Richter scale to the Telegram application in real time. During an earthquake, there are changes in pressure and shifts in the earth that produce seismic waves. These waves are recorded by a seismograph and then converted into a seismic graph. The success of this research is measured based on the system's ability to detect earthquake events and produce detection values in accordance with sensor measurements in real time, which are then processed using a formula from the British Geological Survey introduced by Charles F. Richter. The sensitivity of the adxl 335 accelerometer sensor in the datasheet is a minimum of 0,27V/g maximum 0,33V/g. After conducting several tests, the sensitivity of the adxl335 sensor was recorded in the X axis at 0.29V/g, the Y axis at 0.27V/g, and the Z axis at 0.31V/g. This accelerometer sensor sensitivity value is in accordance with the standards listed in the datasheet. In testing wifi connectivity, the average time used is 10 seconds. Meanwhile, the vibration sensor has produced a voltage value that matches the level of pressure received. Keywords: Indonesia, Earthquake, Accelerometer Sensor, Vibrating Sensor, NodeMCU ESP8266
