Abstract Dairy processing industry is one of the industries that give positive contribution to the economic growth, however it also contributes in many impacts on the environment, as well as milk powder product manufactured by PT X. The main objective of this study was to determine the most significant environmental impact caused by production and transportation of milk powder in bag 250 gram (Product A) and milk powder in sachet 40 gram (Product B) using Life Cycle Assessment (LCA) methodology. The boundary of the LCA study is “cradle to gate”, including: materials production, materials transportation from supplier to the PT X factory, manufacture of milk powder in PT X, and distribution of the products from factory to distributor. Four impact categories will be calculated on this study: global warming potential (GWP), eutrophication potential (EP), acidification potential (AP), and photochemical oxidant creation potential (POCP). The impact assessment was calculated by software SimaPro v.8.3.2 faculty license, and the calculation result validated manually by Microsoft Excel. The result of environmental impact calculation shows that Susu B gives greater environmental impact on the GWP category of 1,7016 kg CO2 eq/kg compared to Product A which is 1.3245 kg CO2 eq/kg. For the POCP, AP and EP categories, the potential environmental impacts for Product A and Product B are relatively similar. The material production subsystem has the highest environmental impact on GWP, POCP, AP and EP categories for both Product A and Product B. In particular, production activity in PT X also contributes to GWP. The amount of environmental costs associated with cradle-to-gate life cycle of 1 kg of milk powder is Rp 2.637,00 for Product A and Rp 3.048,00 for Product B. An environmental impact reduction strategy can focus on reducing GWP with electricity usage efficiency, developing a material supplier selection plan with environmental impacts of material production as one of criteria, and prioritizing packaging-design products as Product A because it provides a smaller GWP environment impact.
