Abstract

PLTU Tenayan di Pekanbaru, Riau, dengan kapasitas terpasang sebesar 2 × 110 MW memerlukan sistem komunikasi yang andal untuk mendukung integrasi antara Programmable Logic Controller (PLC) dan Distributed Control System (DCS) pada sistem udara. Namun, penerapan teknologi LoRa untuk integrasi PLC–DCS pada lingkungan operasional PLTU Tenayan belum pernah dikaji secara khusus. Penelitian ini bertujuan membuktikan kelayakan teknologi LoRa sebagai solusi komunikasi nirkabel industri untuk mendukung integrasi sistem kontrol di pembangkit listrik. Evaluasi dilakukan melalui simulasi propagasi menggunakan model Log-Distance Path Loss, Okumura–Hata, dan COST-231 Walfisch–Ikegami, serta pengujian lapangan pada frekuensi 915 MHz dalam kondisi Line-of-Sight (LOS) dan Non-Line-of-Sight (NLOS). Pengujian dilakukan pada jarak 35 m dan 75 m dengan variasi air rate 2,4 kbps, 9,6 kbps, dan 38,4 kbps serta daya pancar 10 dBm dan 22 dBm. Kinerja jaringan dievaluasi berdasarkan packet loss, throughput, latency, dan Time on Air. Hasil penelitian menunjukkan bahwa komunikasi LoRa stabil pada kondisi LOS dengan packet loss di bawah 1,5%, throughput yang konsisten, dan latency yang rendah. Pada kondisi NLOS, peningkatan redaman propagasi menyebabkan kenaikan packet loss dan penurunan throughput, terutama pada jarak yang lebih jauh dan daya pancar yang lebih rendah. Konfigurasi air rate 9,6 kbps dan daya pancar 22 dBm memberikan kinerja paling stabil pada lingkungan industri. Hasil ini membuktikan bahwa LoRa layak digunakan sebagai alternatif komunikasi yang relatif murah, hemat energi, dan andal untuk mendukung integrasi PLC–DCS serta meningkatkan keandalan sistem pemantauan dan kontrol pada pembangkit PLN.

Tenayan Power Plant (PLTU Tenayan) in Pekanbaru, Riau, Indonesia, with an installed capacity of 2 × 110 MW, requires a reliable communication system to support data exchange between the Programmable Logic Controller (PLC) and the Distributed Control System (DCS) of the compressed air system. However, the application of LoRa (Long Range) technology for PLC–DCS integration in the operational environment of PLTU Tenayan has not yet been investigated. This study aims to demonstrate the feasibility of LoRa as a wireless industrial communication solution for supporting PLC–DCS integration in power plants. The proposed system was evaluated through propagation simulations using the Log-Distance Path Loss, Okumura–Hata, and COST-231 Walfisch–Ikegami models, followed by field experiments conducted at 915 MHz under both Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) conditions. The experiments were performed over communication distances of 35 m and 75 m, using air rates of 2.4 kbps, 9.6 kbps, and 38.4 kbps, with transmit power levels of 10 dBm and 22 dBm. Network performance was evaluated in terms of packet loss, throughput, latency, and Time on Air (ToA). The experimental results show that LoRa provides stable communication under LOS conditions, with packet loss below 1.5%, consistent throughput, and low latency. Under NLOS conditions, increased propagation loss resulted in higher packet loss and reduced throughput, particularly at longer communication distances and lower transmit power levels. Among the evaluated configurations, an air rate of 9.6 kbps combined with a transmit power of 22 dBm provided the most stable communication performance under industrial propagation conditions. Overall, the results demonstrate that LoRa is a feasible, reliable, and energy-efficient wireless communication solution for supporting PLC–DCS integration and has strong potential as a cost-effective alternative for enhancing monitoring and control system reliability in PLN power generation facilities.
