Tofu is one of the processed soybean foods that are very popular with Indonesian society. Despite the popularity of Tofu, Tofu production in Indonesia is generally small and medium, reaching 500 kg per day, as in the tofu factory in Semanan, West Jakarta. The purpose of this study is to analyze the environmental impact of tofu production in West Jakarta. The life cycle assessment (LCA) approach was used to achieve this goal with SimaPro software for impact calculations. This research applies the LCA cradle to gate, which consists of soybean cultivation, transportation, and tofu production processes. The environmental impacts of tofu production analyzed in this study include global warming, ozone depletion, acidification, and eutrophication. The impact analysis showed that the acquisition of soybeans, which consisted of soybean cultivation and transportation, had the most significant environmental impact with a global warming potential value of 0.882 kg CO 2 eq out of a total of 0.978 CO 2 eq for the whole process.
