Abstract
Simulator panci bertekanan merupakan media pembelajaran penting dalam bidang instrumentasi dan keselamatan proses yang memungkinkan integrasi fungsi kontrol dan proteksi secara jarak jauh berbasis web server. Penelitian ini mengusulkan perancangan dan evaluasi kinerja sistem untuk simulator proses pemanasan air hingga menghasilkan uap jenuh dalam sistem tertutup dengan variabel utama temperatur dan tekanan. Sistem menggunakan ESP32-S3 sebagai kontrol pada plant, protokol MQTT dengan komunikasi aman MQTTS (port 8883) melalui HiveMQ Cloud, serta backend Node.js sebagai middleware untuk pengolahan data real-time dan penyimpanan pada database MySQL. Dashboard berbasis web server memungkinkan autentikasi pengguna serta pemantauan dan pengendalian jarak jauh terhadap parameter temperatur, tekanan, status aktuator, dan kondisi alarm melalui perangkat Android. Simulator ini menerapkan skema Basic Process Control System (BPCS) untuk menjaga kestabilan proses dan Safety Instrumented System (SIS) yang dirancang berdasarkan kerangka Layer of Protection Analysis (LoPA) guna mencegah kondisi overpressure. Evaluasi performa dilakukan menggunakan parameter Quality of Service (QoS) meliputi throughput, delay, jitter, dan packet loss pada level QoS 0, QoS 1, dan QoS 2 dengan durasi pengujian 60–300 detik. Hasil pengujian menunjukkan nilai packet loss sebesar 0% pada seluruh level QoS, delay rata rata sekitar 225 ms untuk QoS 0 dan 237 ms untuk QoS 1, serta jitter di bawah 2,5 ms, sementara QoS 2 menghasilkan latensi lebih tinggi akibat mekanisme four-way handshake. Berdasarkan klasifikasi standar ETSI TIPHON, performa QoS sistem secara keseluruhan berada pada kategori memuaskan, sehingga sistem yang dikembangkan layak diterapkan sebagai platform simulasi laboratorium berorientasi industri dan pembelajaran instrumentasi berbasis IoT.

A pressure vessel simulator constitutes an essential learning medium in instrumentation and process safety, enabling the integration of control and protection functions through a web server–based remote access system. This study proposes the design and performance evaluation of a web server–based operating system for a simulator representing the water heating process to generate saturated steam in a closed system, with temperature and pressure as primary process variables. The system employs ESP32-S3 as the plant controller, MQTT protocol secured with MQTTS (port 8883) via HiveMQ Cloud, and a Node.js backend as middleware for real-time data processing and storage in an MySQL database. A web-based dashboard facilitates user authentication as well as remote monitoring and control of temperature, pressure, actuator status, and alarm conditions via Android devices. The simulator implements a Basic Process Control System (BPCS) to maintain process stability and a Safety Instrumented System (SIS) designed based on the Layer of Protection Analysis (LoPA) framework to prevent overpressure conditions. Performance evaluation is conducted using Quality of Service (QoS) parameters, including throughput, delay, jitter, and packet loss at QoS levels 0, 1, and 2, with testing durations of 60–300 seconds. The results indicate a packet loss of 0% across all QoS levels, average delay of approximately 225 ms for QoS 0 and 237 ms for QoS 1, and jitter below 2.5 ms, while QoS 2 exhibits higher latency due to the four-way handshake mechanism. Based on ETSI TIPHON classification, the overall QoS performance is
categorized as satisfactory, demonstrating that the developed system is suitable as an IoT-based laboratory simulation platform for industrial-oriented learning.
