CARBON FOOTPRINT STUDY ON COAL-BASED ENERGY SYSTEMS IN THE FISHERIES PROCESSING INDUSTRY IN BALI

The fish processing industry is one of the main contributors to regional economic activity in coastal areas.However, its dependence on fossil fuels, especially coal, poses significant environmental problems, especially related to greenhouse gas (GHG) emissions.This study aims to assess the carbon footprint resulting from coal combustion in a fish processing plant in Bali during the operational period.Parameters observed include daily coal consumption, coal ash residue, total CO emissions, and specific carbon footprint.Data analysis revealed a total coal consumption of 765,430 kg, resulting in total CO emissions of 1,382,964.3kg.The average specific carbon footprint was calculated to be 3.98 kg CO/kg product, indicating high carbon intensity relative to industry energy efficiency benchmarks.The study also analyzed the relationship between production output and emissions, as well as the correlation between coal ash production and carbon efficiency.Findings showed inconsistencies between energy use and production levels, with several examples of high emissions accompanied by low output, indicating operational inefficiencies.The results highlight the urgent need for mitigation strategies, including improving boiler efficiency, transitioning to low-carbon fuels, implementing emission control systems, and utilizing coal ash as a secondary feedstock.This research provides baseline data for environmental management planning and contributes to broader efforts in industrial decarbonization and sustainable fish processing practices.
