Abstract

Indonesia, which is rich in natural resources, still relies on coal as its main energy source. However, awareness of sustainability is driving the transition to renewable resources through the implementation of biomass Co-Firing in Steam Power Plants (PLTU). This study analyzes the impact of the implementation of 4% sawdust Co-Firing on boiler performance in Unit 3 of PLTU Banten 3 Lontar, with a capacity of 315 MW, as an effort to support Indonesia's renewable energy mix. Data were collected through observation and interviews to calculate the specific fuel consumption (SFC) and Net Plant Heat Rate (NPHR). The results showed that uneven sawdust distribution affected operational stability, including deviations in motor current and motor load imbalance in the Medium Speed Mill (MSM). The performance of the Primary Air Fan (PAF) decreased, while the Forced Draft Fan (FDF) and Induced Draft Fan (IDF) remained consistent. Although the SFC is slightly higher (0.64–0.67 kg/MWh), the production cost is lower, which is IDR 636.18/kWh compared to IDR 647.70/kWh in Coal Firing, providing an average saving of IDR 11.52/kWh. The NPHR in Co-Firing is lower (2869.04 kCal/kWh) compared to Coal Firing (2955.06 kCal/kWh), indicating better efficiency. This study concludes that the application of sawdust Co-Firing can improve energy generation efficiency, reduce significant operational costs, and support efforts to achieve a renewable energy mix at the Banten 3 Lontar PLTU. Keywords : Co-Firing, Boiler, PLTU, Energy Efficiency, Renewable Energy Indonesia, yang kaya akan sumber daya alam, masih bergantung pada batubara sebagai sumber energi utama. Namun, kesadaran terhadap keberlanjutan mendorong transisi menuju sumber daya terbarukan melalui penerapan Co-Firing biomassa di Pembangkit Listrik Tenaga Uap (PLTU). Penelitian ini menganalisis dampak penerapan Co-Firing sawdust 4% terhadap kinerja boiler di Unit 3 PLTU Banten 3 Lontar, dengan kapasitas 315 MW, sebagai upaya mendukung bauran energi terbarukan Indonesia. Data dikumpulkan melalui observasi dan wawancara untuk menghitung Specific Fuel Consumption (SFC) dan Net Plant Heat Rate (NPHR). Hasil penelitian menunjukkan bahwa distribusi sawdust yang tidak merata memengaruhi kestabilan operasional, termasuk deviasi pada arus motor dan ketidakseimbangan beban motor di Medium Speed Mill (MSM). Kinerja Primary Air Fan (PAF) menurun, sementara Forced Draft Fan (FDF) dan Induced Draft Fan (IDF) tetap konsisten. Meskipun SFC sedikit lebih tinggi (0,64–0,67 kg/MWh), biaya produksi lebih rendah, yakni Rp 636,18/kWh dibandingkan Rp 647,70/kWh pada Coal Firing, memberikan penghematan rata-rata Rp 11,52/kWh. NPHR pada Co-Firing lebih rendah (2869,04 kCal/kWh) dibandingkan Coal Firing (2955,06 kCal/kWh), menunjukkan efisiensi yang lebih baik. Penelitian ini menyimpulkan bahwa penerapan Co-Firing sawdust dapat meningkatkan efisiensi pembangkitan energi, mengurangi biaya operasional yang signifikan, dan mendukung upaya pencapaian bauran energi terbarukan di PLTU Banten 3 Lontar. Kata Kunci : Co-Firing, PLTU, Boiler, Efisiensi energi, Bauran Energi Terbarukan
