Abstract

Pencurian listrik merupakan salah satu penyebab losses daya listrik yang dihadapi oleh PLN. Losses daya listrik ini dapat berdampak pada besaran nilai pendapatan PLN dan dapat berdampak juga pada kinerja dari Travo yang terpasang ke pelanggan. Penelitian ini bertujuan untuk membuat suatu prototype sistem yang dapat mendeteksi dan menginformasikan saat terjadinya pencurian listrik di rumah tinggal, melalui pendeteksian besarnya arus listrik yang dikonsumsi pelanggan, dan menginformasikannya ke pihak PLN melalui komunikasi SMS Gateway jika terindikasi terjadi pencurian listrik. Metode yang digunakan adalah metode prototyping, yang mencakup perancangan dan pembuatan perangkat keras maupun perangkat lunak. Selanjutnya dilakukan proses pengujian terhadap prototype sistem yang dihasilkan untuk mendapatkan data sehubungan dengan kerja sistem. Dari hasil penelitian yang dilakukan, pada kondisi beban terpasang sebesar 2 Ampere, saat terdeteksi besarnya konsumsi arus pemakaian telah melebihi batas pemakaian dari beban terpasang sebesar 2 Ampere, maka prototype sistem akan mengirimkan notifikasi ke PLN melalui komunikasi SMS Gateway, bahwa telah terindikasi terjadi pencurian listrik, dimanainformasi yang dikirim meliputi nomor pelanggan dan alamat dari pelanggan.

Abstract

Voltage monitoring is an important aspect in electrical systems to maintain operational stability and prevent damage to electrical equipment. In systems based on Programmable Logic Controller (PLC), voltage measurement is carried out through an analog input module that converts analog signals into digital data, which is then processed using a scaling method to obtain the actual voltage value. This conversion process has the potential to produce errors due to the limitations of analog input resolution, noise, and measurement device tolerances. This study aims to analyze the error level of DC voltage readings using PLC analog input under overvoltage and undervoltage conditions. The method used is an experimental approach by comparing the reference voltage from an adjustable power supply with the PLC reading results at several voltage variations. The reference voltage is converted into an actual voltage scale using a linear approach, then analyzed using the percentage error method. The results show that the error value ranges from 0% to 1.38%, with an average value of approximately 0.96%, and the highest error occurs under overvoltage conditions. This indicates that the system has good accuracy with relatively small and stable error levels. Therefore, the PLC-based voltage monitoring system is feasible for voltage monitoring applications with an acceptable level of measurement error.
