Textile is a material made from fiber processed into cloth or yarn as raw material for designing clothes, clothing, and other products. PT. Gucci Ratu Textile (Guccitex) is a textile industry that specializes in producing dyeing and printing. The textile production process can potentially pollute the environment, such as liquid waste and emissions. This study aims to identify the potential environmental impacts resulting from each unit of the production process from the textile production process activities at PT. Guccitex. Based on ISO 14040:2006, Life Cycle Assessment (LCA) is a method that can be used to evaluate the environmental impact of an activity or process. The evaluation was carried out to know the magnitude of the environmental effects resulting from the production process activities at PT. Guccitex. The LCA study boundary uses the “gate-to-gate” concept, which includes the yarn purchase stage to the production process stage with a functional unit of 1 kilogram (kg) of each textile product produced. The impact categories that will be reviewed in this study include the Global Warming Potential (GWP), Eutrophication Potential (EP), Acidification Potential (AP), and Human Toxicity Potential (HTP). The potential environmental impacts of dyed fabric products using the CML-IA baseline method are global warming (GWP) of 6.155 x 10-3 kg CO2-eq, acidification (AP) of 5.969 x 10-5 kg SO2-eq, eutrophication (EP) of 4.142 x 10-5 kg PO3 4—-eq, and human toxicity (HTP) of 4.289 x 10-5 kg 1.4 db – eq. Meanwhile, the environmental impacts on printed fabric products are global warming (GWP) of 6.163 x 10-3 kg CO2-eq, acidification (AP) of 6.409 x 10-5 kg SO2-eq, eutrophication (EP) of 4.250 x 10-5 kg PO3 4—-eq, and toxicity to humans (HTP) of 5.284 x 10-5 kg 1.4 db – eq. Based on the normalization results for dyed and printed fabric products, the most significant potential impact is in the acidification impact category (AP) with an average value for both objects amount 7.791135E-14 Pt. The results of the interpretation of the LCA study indicate that the stages that contribute to the most significant impact are at the steps of the production process in terms of the use of coal-fired boilers, where the most considerable pollutant parameter is SO2. Based on the results of the improvement analysis, recommendations for improvements that can be made in reducing the impact of acidification are the use of FDG or Flue Gas Desulphurization technology and injection of limestone (limestone)
