<![CDATA[The Fish Smoking Industry Center in District XIII Koto Kampar produces smoked catfish and generate solid waste, wastewater, and gas emissions from firewood combustion. This study aims to analyze the global warming potential and energy use in the smoked catfish production process using the Life Cycle Assessment (LCA) method with a gate-to-gate system boundary. The analysis includes inventory assessment, impact assessment, and results interpretation. The findings show that total greenhouse gas (GHG) emissions reach 3296.426 tons CO₂-eq per week, with an average of 0.1958 tons CO₂-eq per kilogram of product. The total calorific energy released from firewood use is 731,445 MJ per week, with an average energy requirement of 43.560 MJ per kilogram of product and firewood consumption of 5.808 kg per kilogram of smoked catfish. These results indicate that the smoking process contributes significantly to local GHG emissions. Several environmental management alternatives—including chimney installation, wastewater treatment provision, solid waste valorization, and HACCP implementation—are recommended to mitigate environmental impacts.]]>
