【 摘 要 】

Technological advances sometimes bring negative effects, for example, there are emissions of gas and waste as a result of manufacturing activities. The research was carried out at the bread manufacturing with the intent calculate Life Cycle Inventory and Impact Assessment using life cycle analysis framework in ISO 14040. The stages of this research are from a preliminary study which contains goal definition and scope, followed by literature study, field survey and interview for data acquisition - inventory definition. The final stage is the analysis and conclusion that contains the impact analysis and interpretation of the impact. The impact measured up to the final process of bread making is the packaging stage using the 2002+ impact method. The results are there is the potential human health of 9.39E-05 DALY, ecosystem quality 42 PDF∗m2∗yr, climate change 118 kg CO2 eq and resources 247 MJ Primary. The comparison of baking, injection, and packaging process, it is found that there was a slight increase in damage category of human health and climate change, while no change in ecosystem quality. It is found in the study that the most dominant factor that contributes to environmental impact is the use of electricity.
