Abstract

The national energy transition encourages the application of biomass co-firing technology in Steam Power Plants (PLTU) as an effort to reduce greenhouse gas emissions and increase the renewable energy mix. The success of the implementation of co-firing is greatly influenced by the selection of the right biomass raw materials, considering the trade-off between benefits, costs, and operational risks. This study aims to determine the most optimal co-firing biomass raw materials in coal-fired power plants using the Benefit-Cost–Risk Analysis approach combined with the Analytical Hierarchy Process (AHP) method. The study was conducted on one of the coal-fired power plants in East Java by comparing three alternatives, namely sawdust, rice husks, and coal without co-firing. The weighting of criteria was carried out through expert assessment using AHP paired comparisons. The selected alternatives were then analyzed for their environmental impact using the Life Cycle Assessment (LCA) approach with the scope of cradle to gate. The results show that sawdust has the highest Benefit value, a Benefit–Cost (BCR) ratio above one, and a level of risk that can still be managed compared to other alternatives. The LCA analysis identified boiler units as the main hotspots of environmental impact, so operational improvements were recommended through water-steam system control. This research provides a basis for strategic decision-making in the selection of co-firing biomass that supports the energy transition and environmental sustainability.

Abstract

This study aims to identify the environmental impacts arising from the electricity generation process at PT. X and to determine alternative mitigation scenarios that can be applied to reduce these environmental impacts. Using the Life Cycle Assessment (LCA) approach, the study successfully identified the Cooling Tower as the main hotspot in the generation process, with emissions such as CO?, H?S, NH?, and NO? contributing to global warming potential, acidification potential, eutrophication potential, and human toxicity. Based on the analysis using Analytical Hierarchy Process (AHP), the most effective mitigation alternative to reduce environmental impacts is the use of High Performance Lubricant (HPL) for the Fan Cooling Tower (FCT) system. The use of HPL received the highest priority, with a weight of 46.9% of the total decision, as it can reduce friction and heat, leading to improved energy efficiency and reduced motor power consumption. This research contributes to the development of mitigation strategies that can be applied to achieve a more sustainable, efficient, and environmentally friendly geothermal power plant, while also supporting Indonesia's energy transition.
