Abstract

Pusat data merupakan infrastruktur vital yang membutuhkan sistem pendingin berbasis air, yang berpotensi menimbulkan risiko kebocoran dan kerusakan serius pada perangkat server. Untuk menjawab tantangan ini, penelitian ini merancang dan mengembangkan sistem deteksi kebocoran air yang terintegrasi dengan Human Machine Interface (HMI) untuk pemantauan secara real-time. Sistem memanfaatkan sensor kabel tipe multi-wire yang dihubungkan dengan kontroler ATL700 untuk mendeteksi keberadaan dan lokasi kebocoran secara presisi. Data hasil deteksi dikirimkan ke HMI TK-8070 menggunakan protokol komunikasi Modbus RTU berbasis RS-485 yang andal dalam lingkungan industri. Hasil pengujian menunjukkan bahwa sistem mampu mendeteksi genangan air kecil (1–5 mL) dengan waktu respons antara 1,27 hingga 2,43 detik tergantung sensitivitas sensor. Komunikasi RS-485 tetap stabil hingga jarak 30 meter, meskipun terjadi peningkatan delay seiring panjang kabel bertambah. Tampilan visual HMI memberikan peringatan dini dengan delay rata-rata 1,68 detik, menunjukkan bahwa sistem ini efektif, akurat, dan dapat diandalkan untuk mengurangi risiko kerusakan akibat kebocoran air di pusat data. ----- Data centers are critical infrastructures that rely on water-based cooling systems, which pose a risk of leakage and potential damage to server equipment. To address this issue, this study developed a water leak detection system integrated with a Human Machine Interface (HMI) for real-time monitoring. The system utilizes multi-wire cable sensors connected to an ATL700 controller to accurately detect the presence and location of water leaks. Detection data is transmitted to the TK-8070 HMI via the Modbus RTU protocol over RS-485, known for its reliability in industrial environments. Test results demonstrate that the system can detect small water puddles (1–5 mL) with a response time ranging from 1.27 to 2.43 seconds, depending on the sensor's sensitivity. RS-485 communication remained stable up to 30 meters, although response delay increased with cable length. The HMI effectively displays system status visually with an average delay of 1.68 seconds, providing early warnings for operators. The developed system proved to be accurate, reliable, and efficient in mitigating water leak risks in data center environments.
