Abstract
Penelitian ini bertujuan untuk mengidentifikasi dampak lingkungan yang ditimbulkan dari proses pembangkitan listrik di PT. X dan untuk menentukan alternatif skenario mitigasi yang dapat diterapkan untuk mengurangi dampak lingkungan yang dihasilkan. Menggunakan pendekatan Life Cycle Assessment (LCA), penelitian ini berhasil mengidentifikasi Cooling Tower sebagai hotspot utama dalam proses pembangkitan, dengan emisi gas rumah kaca (CO₂), H₂S, NH₃, dan NOₓ yang berkontribusi pada global warming potential, acidification potential, eutrophication potential, serta human toxicity. Berdasarkan hasil analisis Analytical Hierarchy Process (AHP), alternatif mitigasi yang paling efektif untuk menurunkan dampak lingkungan adalah Penggunaan High Performance Lubricant (HPL) untuk sistem Fan Cooling Tower (FCT). Penggunaan HPL mendapat prioritas tertinggi dengan bobot 46.9% dari keseluruhan keputusan, karena dapat mengurangi gesekan dan panas, yang berujung pada peningkatan efisiensi energi dan penurunan konsumsi daya motor. Penelitian ini memberikan kontribusi dalam mengembangkan strategi mitigasi yang dapat diterapkan untuk mencapai pembangkit listrik panas bumi yang lebih berkelanjutan, efisien, dan ramah lingkungan, serta mendukung transisi energi di Indonesia.

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 CO₂, H₂S, NH₃, and NOₓ 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.
