Abstract
Kebutuhan akan pemantauan konsumsi sumber daya secara akurat dan real-time menjadi semakin penting seiring meningkatnya kesadaran akan efisiensi penggunaan air dan energi listrik. Penelitian ini bertujuan untuk merancang dan menguji kinerja sebuah sistem monitoring penggunaan air dan daya listrik terpakai berbasis Internet of Things (IoT), yang mengintegrasikan sensor flow meter YF-S201 untuk mengukur volume air dan sensor PZEM-004T V3.0 untuk mengukur parameter kelistrikan (tegangan, arus, daya, dan energi) dalam satu platform terpadu. Sistem dibangun menggunakan mikrokontroler ESP32 sebagai unit kendali utama, solenoid valve yang dikendalikan melalui relay sebagai aktuator pengisian air otomatis, Firebase Realtime Database sebagai media penyimpanan dan pertukaran data secara real-time, serta aplikasi Android berbasis Kodular sebagai antarmuka pengguna untuk memantau dan mengendalikan sistem dari jarak jauh. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan pendekatan pengembangan sistem terapan, di mana sistem diuji secara langsung pada kondisi operasional nyata. Hasil pengujian menunjukkan bahwa sistem mampu mengisi air sesuai target volume (5L, 15L, dan 19L) dengan rata-rata persentase error berturut-turut sebesar 1,88%, 1,41%, dan 5,12%, menghasilkan tingkat akurasi rata-rata sistem sebesar 97,1%. Kecenderungan error yang lebih besar pada target volume 19L disebabkan oleh delay respons solenoid valve dan variasi tekanan sumber air. Pada sisi kelistrikan, sensor PZEM-004T menunjukkan akurasi tinggi pada pembacaan tegangan dengan rata-rata error sebesar −0,285%, namun akurasi lebih rendah pada pembacaan arus dengan rata-rata error sebesar −6,44%, yang disebabkan oleh karakteristik sensor current transformer yang kurang presisi pada rentang arus rendah. Sistem juga berhasil menghitung estimasi biaya listrik berdasarkan tarif dasar listrik golongan R-1/1300VA. Dengan hasil tersebut, sistem monitoring yang dikembangkan terbukti mampu bekerja secara optimal sebagai media pemantauan penggunaan air dan energi listrik berbasis IoT secara real-time. ***** The need for accurate and real-time resource consumption monitoring has become increasingly important alongside growing awareness of water and electrical energy efficiency. This research aims to design and evaluate the performance of an Internet of Things (IoT)-based monitoring system for water usage and electrical power consumption, integrating a YF-S201 flow meter sensor to measure water volume and a PZEM-004T V3.0 sensor to measure electrical parameters (voltage, current, power, and energy) within a single integrated platform. The system was built using an ESP32 microcontroller as the main control unit, a solenoid valve controlled through a relay as the actuator for automatic water filling, Firebase Realtime Database as the medium for real-time data storage and exchange, and a Kodular-based Android application as the user interface for remote monitoring and control. The research employed a Research and Development (R&D) method with an applied system development approach, in which the system was tested directly under real operational conditions. Test results show that the system was able to fill water according to target volumes (5L, 15L, and 19L) with average error percentages of 1.88%, 1.41%, and 5.12% respectively, resulting in an average system accuracy of 97.1%. The larger error observed at the 19L target was attributed to solenoid valve response delay and variations in water source pressure. On the electrical monitoring side, the PZEM-004T sensor demonstrated high accuracy in voltage readings with an average error of −0.285%, but lower accuracy in current readings with an average error of −6.44%, attributed to the characteristics of current transformer sensors, which are less precise at low current ranges. The system also successfully calculated estimated electricity costs based on the R-1/1300VA electricity tariff. These results demonstrate that the developed monitoring system is capable of functioning optimally as a real-time IoT-based platform for monitoring water and electrical energy usage.
