Abstract
Pemerintah Indonesia mengupayakan pencapaian Net Zero Emissions (NZE) melalui pengembangan energi baru dan terbarukan (EBT), salah satunya dengan implementasi co-firing biomassa pada Pembangkit Listrik Tenaga Uap (PLTU). Data yang digunakan adalah hasil perbandingan performa sistem sebelum co-firing (15 Mei - 14 Juni 2023) dan setelah co-firing (14 April - 14 Mei 2024), dengan pengambilan data pada pukul 10.00 WITA setiap harinya. Co-firing merupakan metode substitusi sebagian batubara dengan biomassa untuk menghasilkan tenaga listrik. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan co-firing biomassa terhadap siklus Rankine di PLTU Jeranjang serta mengevaluasi kelayakan penerapannya. Metode yang digunakan adalah analisis komparatif dengan menghitung dan membandingkan efisiensi komponen utama PLTU meliputi turbin, pompa, boiler, dan generator, serta efisiensi termal sebelum dan sesudah implementasi co-firing menggunakan pelet sampah dengan komposisi optimal 3%. Hasil penelitian menunjukkan adanya variasi perubahan efisiensi pada komponen utama pembangkit. Generator dan boiler mengalami peningkatan efisiensi, sementara turbin uap dan pompa mengalami penurunan. Efisiensi termal keseluruhan mengalami sedikit penurunan dari 34,08% menjadi 33,83%. Dapat disimpulkan bahwa meskipun implementasi co-firing biomassa memberikan tantangan dalam mempertahankan efisiensi konversi energi, sistem ini masih layak diterapkan dengan optimasi lebih lanjut untuk memaksimalkan manfaatnya

The Indonesian government seeks to achieve Net Zero Emissions (NZE) through the development of new and renewable energy (EBT), one of which is the implementation of biomass co-firing in Steam Power Plants (PLTU). The data used are the results of the comparison of system performance before co-firing (May 15 - June 14, 2023) and after cofiring (April 14 - May 14, 2024), with data collection at 10:00 a.m. WITA every day. Co-firing is a method of partially substituting coal with biomass to generate electricity. This study aims to analyze the effect of biomass co-firing on the Rankine cycle at PLTU Jeranjang and evaluate the feasibility of its application. The method used is comparative analysis by calculating and comparing the efficiency of the main components of the PLTU including turbines, pumps, boilers, and generators, as well as thermal efficiency before and after the implementation of cofiring using waste pellets with an optimal composition of 3%. The results showed variations in efficiency changes in the main components of the plant. The generator and boiler experienced an increase in efficiency, while the steam turbine and pump experienced a decrease. The overall thermal efficiency decreased slightly from 34.08% to 33.83%. It can be concluded that although the implementation of biomass co-firing presents challenges in maintaining energy conversion efficiency, the system is still feasible with further optimization to maximize its benefits.
