Rancang Bangun Electrical Energy Monitoring System Pada Smart Classroom

Pada smart classroom di Departemen Teknik Instrumentasi Institut Teknologi Sepuluh Nopember Surabaya terdapat peralatan listrik seperti AC, lampu, stop kontak, LED projector, dan Personal Computer. Dimulai dari dosen mendapat otorisasi untuk masuk ke smart classroom, kemudian menekan handle pintu untuk masuk ke ruangan. Pada saat itu, sistem monitoring energi listrik mulai untuk beroperasi. Dosen menyalakan peralatan listrik yang ada didalam smart classroom seperti lampu, maka pengukuran dalam penggunaan daya listrik mulai dilakukan. Dengan dirancangnya sistem monitoring energi listrik pada smart classroom dapat menganalisis kebutuhan energi listrik yang digunakan oleh dosen sebagai upaya dalam menghemat penggunaan energi listrik serta mengetahui estimasi biaya yang dikeluarkan untuk menggunakan peralatan listrik di smart classroom secara realtime yang diakses melalui GUI pada PC. Pada perancangan sistem monitoring energi listrik yang akan dilakukan terdapat 3 bagian yaitu sensor untuk mengukur penggunaan energi listrik yaitu power meter digital Schneider Electric tipe iEM 2050 yang tersedia protokol komunikasi modbus, modbus gateway untuk mengambil data dari power meter digital dan mengirimkan data pengukuran ke server, PC yang terdapat monitor digunakan untuk menampilkan GUI berupa hasil pengukuran dari power meter digital tersebut. Sistem monitoring energi listrik dibuat untuk mendukung pembangunan smart classroom di Departemen Teknik Instrumentasi ITS yang diharapkan dapat memonitor penggunaan serta estimasi biaya yang dikeluarkan saat memakai energi listrik di smart classroom. ====================================================================================================== In the smart classroom at the Department of Instrumentation Engineering, Sepuluh Nopember Institute of Technology, Surabaya there are electrical equipment such as air conditioners, lights, sockets, LED projectors, and Personal Computers. Starting from the lecturer getting authorization to enter the smart classroom, then pressing the door handle to enter the room. At that time, the electrical energy monitoring system started to operate. The lecturer turns on the electrical equipment in the smart classroom such as a lamp, then the measurement in the use of electrical power begins to be carried out. With the design of the electrical energy monitoring system in the smart classroom, it can analyze the electrical energy needs used by lecturers as an effort to save the use of electrical energy and find out the estimated costs incurred for using electrical equipment in the smart classroom in realtime which is accessed via a GUI on a PC. In the design of the electrical energy monitoring system that will be carried out there are 3 parts, namely sensors to measure the use of electrical energy, namely the Schneider Electric digital power meter type iEM 2050 which is available modbus communication protocol, modbus gateway to retrieve data from a digital power meter and send measurement data to the server, A PC with a monitor is used to display a GUI in the form of measurement results from the digital power meter. The electrical energy monitoring system was created to support the construction of a smart classroom in the ITS Instrumentation Engineering Department which is expected to monitor the use and estimated costs incurred when using electrical energy in the smart classroom
