RANCANG BANGUN PROTOTYPE SISTEM MONITORING DAN PENGENDALIAN PERANGKAT ELEKTRONIK DI MASJID BAITUL MARIFAH POLTEKBANG SURABAYA BERBASIS IOT MENGGUNAKAN WEBSITE

Penggunaan energi listrik di masjid sering kali tidak terkontrol secarefisien akibat belum tersedianya sistem pemantauan dan pengendalian otomatiyang terintegrasi. Hal ini menyebabkan pemborosan daya serta kesulitan dalam
pengelolaan perangkat elektronik yang beroperasi dalam jangka waktu panjang.Untuk menjawab permasalahan tersebut, penelitian ini bertujuan merancang damembangun sistem monitoring dan pengendalian perangkat elektronik berbasisInternet of Things (IoT) yang terintegrasi dengan antarmuka website dan dapadiakses secara realtime. Sistem ini dirancang untuk mendukung implementasikonsep smart masjid melalui efisiensi energi dan otomasi pengelolaan listrik.Penelitian menggunakan pendekatan R&D model 4D (Define, Design, Develop,Disseminate), dengan mengintegrasikan mikrokontroler ESP32, sensor PZEM004T untuk mengukur parameter listrik (tegangan, arus, daya, dan energi), sertaFirebase sebagai platform komunikasi data berbasis cloud. Pengujian dilakukapenilaian dari validator untuk mengevaluasi akurasi pembacaan data dan stabilitakendali perangkat melalui website. Hasil menunjukkan bahwa sistem mampu memberikan pembacaan data arus, tegangan, daya sesuai dengan data di lapangayang dibandingkan alat ukur standar berupa clampmeter serta menjalankan fungsikendali secara responsif dan stabil. Penelitian ini memberikan kontribusi praktidalam pengembangan sistem hemat biaya dan mudah diterapkan untuk digitalisasimanajemen energi di masjid, serta menjadi langkah awal menuju penerapateknologi smart building skala mikro berbasis IoT.

============================================================
Electrical energy usage in mosques is often inefficiently controlled due the lack of an integrated automatic monitoring and control system. This results power wastage and difficulty in managing electronic devices that operate for longperiods of time. To address these issues, this study aims to design and build anInternet of Things (IoT)-based electronic device monitoring and control system thatis integrated with a website interface and can be accessed in realtime. This systemis designed to support the implementation of the smart mosque concept through
energy efficiency and electricity management automation. The study uses a 4D(Define, Design, Develop, Disseminate) R&D model approach, by integrating anESP32 microcontroller, a PZEM-004T sensor to measure electrical parametersVoltage, current, power, and energy), and Firebase as a cloud-based datacommunication platform. Testing is carried out by assessing the validator transmit data readings and device control stability via the website. The results showthat the system is able to provide current, Voltage, and power data readings accordance with field data compared to standard measuring instruments in the form of a Clampmeter and performs control functions responsively and stably. Thisresearch provides a practical contribution in the development of a cost-effectiand easy-to-implement system for digitalizing energy management in mosques, well as being the first step towards implementing IoT-based micro-scale smartbuilding technology.
