Aplikasi Monitoring Smartlab Menggunakan Algoritma Enigma Berbasis Android (Studi Kasus : Laboratorium Komputer Dasar Stt Pln)

Smartphones based on Android, iOS, or Windows Phone is very fast technology in accessing information and mobile data services, this technology allows us to work anytime and anywhere is not limited by location and time. need fast and accurate information on basic computer lab researchers STT PLN background create an application that serves to monitor the conditions and activities in a computer lab by applying mobile technology at Smart Information Systems Laboratory in the College of Engineering PLN. It is hoped that with the development of these applications can facilitate laboratory users to access data and information and can control the computer lab activities are based on Android. At present the STT PLN elementary computer lab, for security and energy savings have been designed using technology to detect finger print fingerprint and smart cards to control the work of power tools that exist in the computer lab. So the lab assistant was able to turn on and turn off the electrical appliances automatically, the smart card has to work according to the contract of lectures so that students are expected to perform tapping the smart card is otomatais and students are able to turn on the computer and access the computer in accordance with the schedule of his courses, as well as with the lecturer. And on smartlab It can be detected using a personal schedule and access doors can be made of printed reports, and all the activities that have been automated is expected to be monitored by mobile so they invented smartlab monitoring applications in basic computer lab PLN.Metode STT is composed of several stages namely initialization IP and subnet mask, forming connections and wireless network, send data requests to the Arduino to send characters, sends a data request to Arduino by sending a character, receive data from arduino and make a key partner of the algorithm enigma, sending the key pair, the results appear on androi
