Abstract

As a country that is surrounded by three oceans and plate is an active volcano, Indonesia has a huge potential of impending earthquakes, tectonic or volcanic either. Because of its frequent earthquake occurred in Indonesia at the moment, it takes an earthquake vibration monitoring system that can be accessed publicly. Vibration monitoring system of earthquakes in real-time can provide information related to the General besar-kecilnya the vibrations of an earthquake happens. With current internet technologies, like the Internet of things, allowing the development of a monitoring system of earthquakes in realtime in which the system is connected online. With this author makes a design tool where tool use accelerometer sensor ADXL 335 with arduino controller that is integrated with the web server using the HTTP protocol and ethernet shield as a media delivery data. Results of testing the sensor sensitivity against vibrations with the default value of the ADXL 335 accelerometer sensor datasheet which value Xout of 0.32 V/g. sensor stability test results in the test scenario can be from. In the first test in 5.3562 can be the value of SR on the load for a vibrating weighing 1.5 kg, and the value of 5.6184 SR with a load of 2,1 kg, as well as the value of 6.9872 SR on load 3.2 kg can be viewed with the same method. Testing the quality of the author's network using provider 3 with LTE networks. In scenario testing conducted as many as 3 times with different interval values obtained the value throughput at intervals of 1 second 2,201,837 bytes/s, 15 seconds interval of 379,132 bytes/s, interval 20 seconds of 274,611 bytes/s, and 30 second intervals of 238,274. On delay parameters obtained results of 0.057 s in 1 second intervals, 0.077 s in the interval of 15 seconds, 0.067 s at intervals of 20 seconds, and 0.073 s at intervals of 30 seconds. Then the value of the packet loss results obtained from capture wireshark where each test produces a value of 0% means no packet lost when testing takes place. Keywords: Accelerometer, Arduino, Internet of things (IoT), earthquakes, web server.
