Abstract

The implementation of biomass co-firing in coal-fired power plants has become one of Indonesia’s transitional energy strategies to support carbon emission reduction in the electricity sector. However, the integration of biomass into coal combustion systems may affect operational performance and technical efficiency. This study titled Technical Efficiency of Coal-Fired Power Plants at Electric Power Generation Companies in the Implementation of Biomass Co-Firing aims to analyze the technical efficiency of coal-fired power plants within an electric power generation company before and after the implementation of biomass co-firing using the Stochastic Frontier Analysis (SFA) approach. The study employs monthly panel data from four coal-fired power plant units in Java over the 2017–2024 period. The estimation model applies a translog production function using the one-stage Battese and Coelli (1995) approach. The results indicate that the average technical efficiency of power plants remains relatively high after the implementation of biomass co-firing. The adoption of biomass co-firing has not significantly reduced technical efficiency, as the proportion of biomass in the fuel mix remains relatively low. In addition, plant age and biomass co-firing significantly influence technical inefficiency. These findings suggest that biomass co-firing can serve as a feasible transitional energy strategy without substantially disrupting the operational performance of coal-fired power plants.

Abstract

Kegiatan pengabdian masyarakat ini dilaksanakan di Desa Gunungsari, Kecamatan Beji, Kabupaten Pasuruan, dengan tujuan meningkatkan kapasitas usaha mikro berbasis potensi lokal, khususnya tanaman siwalan. Program difokuskan pada tiga aspek utama, yaitu peningkatan nilai tambah melalui pelatihan pengolahan siwalan menjadi manisan, digitalisasi pemasaran produk, serta pendampingan penerbitan Nomor Induk Berusaha (NIB). Metode pelaksanaan dilakukan melalui sosialisasi, pelatihan, pendampingan, serta evaluasi dengan pre-test dan post-test untuk mengukur peningkatan pengetahuan dan keterampilan peserta. Peserta tidak hanya mampu mengolah siwalan menjadi produk bernilai tambah dengan kemasan lebih higienis, tetapi juga memahami strategi pemasaran digital untuk memperluas pasar serta memperoleh legalitas usaha berupa NIB. Dengan demikian, kegiatan ini berhasil meningkatkan literasi bisnis, keterampilan, dan legalitas usaha masyarakat, yang diharapkan mampu mendorong pertumbuhan ekonomi lokal secara berkelanjutan.
