RANCANG BANGUN SISTEM PENCATATAN KWH METER BERBASIS WEB

Abstract

Energi listrik merupakan sumber energi yang sangat penting bagi kehidupan manusia baik untuk kegiatan industri, kegiatan komersial, maupun dalam kehidupan sehari-hari rumah tangga. Peningkatan jumlah pelanggan mengarah pada peningkatan tingkat konsumsi listrik. Hal ini disebabkan karena semakin banyak individu yang membutuhkan unit listrik dalam jumlah besar maka konsumsi juga semakin meningkat. Tetapi pelanggan listrik seringkali tidak menyadari adanya kenaikan konsumsi daya pada rumah mereka. Sehingga diperlukan suatu teknologi yang dapat mengatasi masalah tersebut. Penelitian Rancang Bangun Pencatatan KWH Meter Berbasis Web dilakukan menggunakan sensor PZEM-004T, NodeMCU ESP8266, NodeMCU ES32, LoRa SX1728, LCD 20x4, RTC DS3231, LED, dan Buzzer. Komponen_komponen tersebut mengolah arus, tegangan, daya, dan energi kemudian dikirimkan ke website. Ketika hasil pembacaan sensor daya melewati batas maksimum yang ditentukan, buzzer akan berbunyi dan LED akan berkedip. Dalam pengujian akurasi sensor didapatkan nilai kesalahan pembacaan tegangan sebesar 0,25%, nilai kesalahan pembacaan arus sebesar 4,75%, nilai kesalahan pembacaan daya sebesar 1,625%, dan nilai kesalahan pembacaan energi sebesar 9,85%. Dalam pengujian transmisi data didapatkan nilai delay sebesar 52,7613 milidetik, nilai RSSI sebesar -118,548 dBm, dan nilai packet loss sebesar -0,347697368.

Electrical energy is a very important source of energy for human life, both for industrial activities, commercial activities, and in everyday household life. An increase in the number of customers leads to an increase in the level of electricity consumption. This is because more and more individuals require large amounts of electricity, the higher the consumption. But electricity customers are often not aware of the increase in power consumption in their homes. So we need a technology that can solve this problem. Therefore, the research was made of a Website-Based Monitoring System for Electricity Usage in Housing Area with components such as PZEM-004T sensor, NodeMCU ESP8266, NodeMCU ES32, LoRa SX1728, 20x4 LCD, RTC DS3231, LED, and Buzzer. These components process current, voltage, power, and energy then send it to the website. When the power sensor reading exceeds the specified maximum limit, the buzzer will sound and the LED will flash. In testing the sensor accuracy, the voltage reading error value is 0.25%, the current reading error value is 4.75%, the power reading error value is 1.625%, and the energy reading error value is 9.85%. In testing the data transmission, the delay value is 52.7613 milliseconds, the RSSI value is -118.548 dBm, and the packet loss value is -0.347697368.
