Abstract
Pengelolaan utilitas air bersih Gedung Tower 2 ITS sering kali menghadapi kendala asimetri informasi akibat penerapan sistem meteran makro yang terpusat. Penelitian ini merancang dan mengimplementasikan sistem monitoring air granular tingkat lantai berbasis Internet of Things (IoT) pada Lantai 7 Gedung Tower 2 ITS. Arsitektur dibangun dengan menghubungkan sensor ultrasonic water meter Huizhong SCL-61H ke mikrokontroler ESP32 menggunakan protokol Modbus RTU via konverter RS-485. Data telemetri dienkapsulasi menjadi payload JSON untuk ditransmisikan melalui protokol MQTT menuju platform middleware Home Assistant pada server. Hasil uji skala mikro menunjukkan akurasi presisi tingkat industri dengan nilai Mean Absolute Percentage Error (MAPE) sebesar 4,15%. Pemantauan longitudinal membuktikan ketahanan sistem melalui algoritma connection watchdog pada ESP32 yang andal memulihkan koneksi secara mandiri pasca-mengalami gangguan stabilitas jaringan (connection timeout) selama lebih dari 63 jam pada Wi-Fi kampus ITS-WIFI-TW2. Analisis komparatif menyajikan data bahwa konsumsi Lantai 7 menyumbang beban utilitas aktual fluktuatif sebesar 11,00% hingga 19,72% terhadap keseluruhan gedung. Melalui entitas Daily Usage Alert, sistem terbukti andal mengisolasi fluktuasi anomali dan mempermudah identifikasi potensi kebocoran. Inovasi granular monitoring ini berkontribusi nyata mendukung gerakan Smart Eco Campus ITS dan SDGs khususnya SDG 6 (Air Bersih dan Sanitasi), SDG 11 (Kota dan Komunitas Berkelanjutan), dan SDG 12 (Konsumsi dan Produksi yang Bertanggung Jawab) serta mampu menyajikan data yang dapat digunakan manajemen sebagai dasar perumusan kebijakan terkait sumber daya air.

Clean water utility management in the ITS Tower 2 Building often faces information asymmetry challenges due to the implementation of a centralized macro-metering system. This study designs and implements an Internet of Things (IoT)-based floor-level granular water monitoring system on the 7th Floor of the ITS Tower 2 Building. The architecture is built by connecting a Huizhong SCL-61H ultrasonic water meter sensor to an ESP32 microcontroller using the Modbus RTU protocol via an RS-485 converter. Telemetry data is encapsulated into JSON payloads to be transmitted via the MQTT protocol to the Home Assistant middleware platform on the server. The results of the micro-scale test demonstrate industrial-grade precision accuracy with a Mean Absolute Percentage Error (MAPE) value of 4.15%. Longitudinal monitoring proves the system's resilience through a connection watchdog algorithm on the ESP32, which reliably recovers the connection autonomously after experiencing network stability disruptions (connection timeout) for more than 63 hours on the ITS-WIFI-TW2 campus Wi-Fi. Comparative analysis presents data showing that the 7th Floor consumption contributes a fluctuating actual utility load of 11.00% to 19.72% to the entire building. Through the Daily Usage Alert entity, the system is proven reliable in isolating anomalous fluctuations and facilitating the identification of potential leaks. This granular monitoring innovation significantly contributes to supporting the ITS Smart Eco Campus movement and the SDGs, particularly SDG 6 (Clean Water and Sanitation), SDG 11 (Sustainable Cities and Communities), and SDG 12 (Responsible Consumption and Production), while also capable of providing data that management can use as a basis for policy formulation regarding water resources.
