Abstract

Industri pemurnian Crude Palm Oil (CPO) menjadi minyak goreng memerlukan sistem kontrol presisi untuk menjaga efisiensi proses dan kualitas produk, khususnya pada metode Continuous Counter-Current Extraction (CCCE) berbasis pelarut etanol yang sensitif terhadap rasio alir dan suhu. Penelitian ini merancang dan mengimplementasikan sistem Supervisory Control and Data Acquisition (SCADA) berbasis Internet of Things (IoT) menggunakan protokol MQTT untuk pemantauan dan pengendalian mini plant secara real-time. Sistem mengintegrasikan dua PLC Mitsubishi FX3U-14MT dengan IoT Gateway KEPServerEX melalui Modbus RTU (RS-232). Data proses dipublikasikan ke broker MQTT (EMQX), disimpan pada Azure SQL Database, dan divisualisasikan melalui antarmuka SCADA berbasis C# dan .NET Framework. Pengujian Quality of Service (QoS) dilakukan pada QoS 0, 1, dan 2 dengan parameter throughput, delay, jitter, dan packet loss menggunakan Wireshark. Hasil menunjukkan packet loss sebesar 0% dan jitter 0,16–1,13 ms pada seluruh skenario. Delay rata-rata tercatat 185,49 ms (QoS 0), 258,24 ms (QoS 1), dan 321,44 ms (QoS 2), dengan throughput 17,27–31,17 Kbps. Berdasarkan indeks ETSI TIPHON, QoS 0 dan QoS 1 memperoleh nilai 3 (Memuaskan), sedangkan QoS 2 bernilai 2,75. Secara keseluruhan, QoS 1 direkomendasikan sebagai konfigurasi paling optimal untuk sistem SCADA real-time.

The refining of Crude Palm Oil (CPO) into cooking oil requires precise control systems to ensure process efficiency and product quality, particularly in Continuous Counter-Current Extraction (CCCE) using ethanol solvent, which is sensitive to flow ratio and temperature variations. This study designs and implements an Internet of Things (IoT)–based Supervisory Control and Data Acquisition (SCADA) system using the MQTT protocol for real-time monitoring and control of a cooking oil mini plant. The system integrates two Mitsubishi FX3U-14MT PLCs with the KEPServerEX IoT Gateway via Modbus RTU (RS-232). Process data are published to an MQTT broker (EMQX), stored in an Azure SQL Database, and visualized through a SCADA interface developed in C# using the .NET Framework. Network performance is evaluated under MQTT Quality of Service (QoS) levels 0, 1, and 2 by analyzing throughput, delay, jitter, and packet loss using Wireshark. The results show 0% packet loss and very low jitter ranging from 0.16 to 1.13 ms across all scenarios. Average delay increases with QoS level, reaching 185.49 ms (QoS 0), 258.24 ms (QoS 1), and 321.44 ms (QoS 2), while throughput ranges from 17.27 to 31.17 Kbps. Based on ETSI TIPHON indices, QoS 0 and QoS 1 achieve a score of 3 (Satisfactory), whereas QoS 2 scores 2.75. Overall, QoS 1 is recommended as the optimal configuration for real-time SCADA applications.
