Abstract

Hukum Kirchhoff merupakan dasar analisis rangkaian listrik kompleks yang mencakup prinsip kekekalan arus (Hukum I) dan tegangan (Hukum II). Penelitian ini mengkaji penerapannya dalam rangkaian jembatan Wheatstone melalui metode teoretis dan simulasi. Hukum Kirchhoff I menyatakan total arus masuk-cabang sama dengan arus keluar, sementara Hukum II menegaskan jumlah aljabar tegangan dalam loop tertutup bernilai nol. Kedua aturan ini menjadi kunci dalam analisis rangkaian listrik tak-seimbang yang tidak dapat diselesaikan dengan kombinasi seri-paralel sederhana. Studi ini melibatkan empat simulator yang berbeda: Circuit Simulator Applet, Circuit Lab (C-Lab), Circuit Wizard, PhET, TinkerCAD membuktikan konsistensi hasil terhadap perhitungan manual (teoretis). Hasilnya penerapan rangkaian jembatan wheatstone memiliki dua kategori yang bersifat balance dan tidak balance dimana perbedaannya terletak pada nilai VAB & IAB -nya. Semakin besar nilai VAB maka laju VAB akan semakin cepat dan semakin tidak stabil. Experimen sederhana ini mengkonfirmasi Hukum Kirchhoff sebagai alat analisis rangkaian jembatan Wheatstone sekaligus mengungkap keterbatasan praktis dalam implementasi fisik melalui pendekatan simulasi.

Abstract

The increasing demand for energy presents challenges in efficient energy management. This study aims to develop and implement an Internet of Things (IoT)-based energy monitoring system called SENSE Plug, integrated with a Fiber To The Home (FTTH) network at the Universitas Pendidikan Indonesia campus laboratory. The system is designed to monitor real-time electricity consumption, detect voltage anomalies, and manage the electrical usage of connected electronic devices. The research uses an experimental approach by designing and testing the system in the laboratory. Data was collected using the PZEM-004T sensor connected to the NodeMCU ESP8266 microcontroller, with the measurements displayed on an OLED screen and sent to the IoT Cloud for remote monitoring. The system was tested on various electronic devices to measure voltage, current, active power, and power factor. The results indicate that the SENSE Plug system achieved high accuracy, with an average error of 0.44% for voltage and 0.41% for current. The system can also detect voltage anomalies and automatically disconnect the power supply to prevent damage to devices. In conclusion, SENSE Plug contributes to improving energy efficiency and offers a solution applicable to smart labs and other building environments
