ABSTRAK/ABSTRACT

Sistem Chiller Management System (CMS) yang digunakan pada Data Center memiliki peran penting dalam memantau kualitas air pendingin agar performa sistem pendingin tetap optimal. Namun, sistem monitoring yang digunakan saat ini masih memiliki keterbatasan dalam mengintegrasikan seluruh parameter kualitas air, belum menyediakan penyimpanan data historis secara lengkap, serta belum dilengkapi dengan fitur grafik trending dan alarm notification yang mendukung tindakan preventif ketika terjadi penurunan kualitas air. Tugas akhir ini bertujuan merancang dan membangun prototipe integrasi serta peningkatan Chiller Management System (CMS) yang mampu melakukan pemantauan kualitas air secara real-time, menampilkan data historis dalam bentuk grafik trending, memberikan alarm notification ketika parameter kualitas air berada di luar batas aman, serta mengevaluasi tingkat kepuasan pengguna terhadap sistem yang dikembangkan. Sistem dikembangkan menggunakan ESP32 sebagai mikrokontroler utama, komunikasi Modbus RTU melalui modul MAX485 dan USB RS485 Adapter, database MySQL/phpMyAdmin, serta dashboard berbasis web yang dikembangkan menggunakan Visual Studio Code. Hasil perancangan menunjukkan bahwa sistem mampu melakukan akuisisi data, transmisi data, penyimpanan database, visualisasi dashboard, alarm notification, serta grafik trending secara real-time. Sistem juga mampu menyimpan data historis sehingga mempermudah teknisi dalam melakukan analisis perubahan kualitas air dan mendukung tindakan preventive maintenance terhadap sistem pendingin Chiller di Data Center. Selain itu, telah disusun instrumen evaluasi kepuasan pengguna berbasis Google Form menggunakan skala Likert sebagai media untuk menilai aspek kemudahan penggunaan, tampilan dashboard, fungsi alarm notification, grafik trending, dan manfaat sistem sebagai dasar evaluasi terhadap prototipe yang dikembangkan, dengan nilai 4,69 dari 5 yang artinya sangat baik untuk respon dari operator terhadap prototipe yang telah dibuat.

The Chiller Management System (CMS) used in Data Centers plays a crucial role in monitoring cooling water quality to ensure optimal cooling system performance. However, the existing monitoring system still has limitations in integrating all water quality parameters, providing comprehensive historical data storage, and supporting trending graphs and alarm notifications for preventive actions when water quality deteriorates. This final project aims to design and develop a prototype for the integration and enhancement of the Chiller Management System (CMS) capable of monitoring water quality in real time, displaying historical data through trending graphs, providing alarm notifications when water quality parameters exceed predefined thresholds, and developing a user satisfaction evaluation instrument for the proposed system. The system was developed using an ESP32 as the main microcontroller, Modbus RTU communication through a MAX485 module and USB RS485 Adapter, a MySQL/phpMyAdmin database, and a web-based dashboard developed using Visual Studio Code. The developed prototype successfully performed real-time data acquisition, data transmission, database storage, dashboard visualization, alarm notifications, and trending graph visualization. In addition. Furthermore, a user satisfaction questionnaire based on Google Forms and a five-point Likert scale was designed to evaluate system usability, dashboard interface, alarm notification features, trending graph functionality, and the overall benefits of the developed prototype, with a score of 4.69 out of 5, which indicates an excellent response from the operators to the prototype that was created.
