Fresh milk is produced by cows which are nurtured and milked by dairy farmers. The fresh milk is collected at Cooperation on Milk Warga Mulya then is processed into pasteurized fresh milk and packed in the cup. Whole activities are influenced by scale of ownership, type of milking process and energy usage for conducting activities. So far effect these activities on environment was not calculated and predicted. The objectives of this research was to implement Life Cycle Assessment (LCA) on fresh milk production which was packed with a plastic cup. Some parameters were considered such as milking technique and number of cows at every farmers. The LCA is a method that can be used to calculate the environmental impact of fresh pasteurized milk production. The samples were 10 dairy farmers as member of Milk Cooperation Warga Mulya at Sleman Regency - Yogyakarta Special Province. The process was started from milking process at farmers, then picking up the fresh milk, receiving milk at Cooperation and then milk processing or pasteurization. All energy, waste and others were collected, calculated, analyzed and then determined into environmental effect category. The results showed, that the energy usage for carrying out all activities was reached by farmers with small livestock group 2.29 MJ/l. The highest emission was gained by pasteurization process released 47.387 g/l CO2 equivalent, 0.0564 g/l SO2, 0.482 g/l NOx and 0.00244 g/l CH4. Then the highest impact to environment was contributed by pasteurization process as follow Global Warming Potential (GWP) 0.0474 kg CO2 equivalent; Acidification Potential (AP) 0.000394 kg SO2 equivalent and Eutrophication Potential (EP) 6.27 x 10-5 kg PO43- equivalent.
