Abstract

Internet of Things (IoT) merupakan konsep yang bertujuan untuk melakukan suatu tindakan terhadap perangkat elektronik baik dikontrol maupun monitoring melalui internet. Tentunya pemanfaatan IoT membantu dan memudahkan segala aktivitas manusia. Kegiatan pengabdian kepada masyarakat yang dilakukan yaitu mengenalkan siswa SMKN 1 Brebes membuat IoT sederhana menggunakan Raspberry PI. Metode yang digunakan adalah penentuan objek, perencanaan, pelaksanaan dan evaluasi. Hasil kegiatan yang telah dilaksanakan siswa dapat mengidentifikasi cara kerja maupun pembuatan IoT seperti mengontrol led dan monitoring suhu menggunakan sensor DHT melalui smarthphone Android.

Abstract

Earthquakes are natural disasters that can occur without warning. Earthquakes originate from vibrations in the earth's bowels that spread to the surface caused by cracks in the earth breaking and shifting violently. Anticipating the impact of an Earthquake can be done using an ESP8266 Microcontroller which is integrated with a Piezoelectric Sensor as the Main Sensor. The Piezoelectric Sensor output is sent and saved to a MySQL Database with test parameters in the form of object weight and distance. The output data results are processed in the form of Java Script Object Notation (JSON) and described by Android. The testing stage was carried out using stones weighing 1 kg, 3kg and 5kg and distances of 25cm, 50cm and 75cm. The results of the tool testing produced a vibration value with the lowest value being 24 and the highest value being 601. Earthquake detection is divided into three categories, namely weak, moderate and strong, based on sensor reading values. The weak category is set in the value range 24-106, moderate in the range 107-199, and strong for reading values above 200.
