<![CDATA[Background: Air quality in Makassar City has an index of 56 (moderate category) and is expected to worsen by 2045 as pollution increases. This study offers a solution utilizes snake plants (Sansevieria trifasciata) as air biofiltration agents to absorb pollutants such as benzene, formaldehyde, and trichlorethylene. In addition, unproductive snake plant leaves are processed into liquid organic fertilizer through a fermentation process using Lactobacillus sp. Methods: This innovation was implemented through a partnership between the community and the government, involving the planting of 6–8 mother-in-law's tongue plants per household and the processing of leaf waste into organic fertilizer. The approach used was a mixed method that included testing the effectiveness of biofiltration, producing liquid organic fertilizer (POC), conducting an economic analysis, and reviewing the literature to assess the effectiveness of mother-in-law's tongue plant biofiltration. Findings: This journal has the potential to improve urban air quality, prevent respiratory diseases, and reduce plant waste accumulation that can produce methane gas. The fermentation process with Lactobacillus sp. also enriches organic content and reduces unpleasant odors, resulting in environmentally friendly organic fertilizer with economic value. Conclusion: The combination of air biofiltration and organic fertilizer production from fermented mother-in-law's tongue using Lactobacillus sp. is an innovative and sustainable approach to tackling air pollution and supporting community-based green economic development. Novelty/Originality of this article: The novelty aspect refers to the new or innovative elements in a research study that distinguish it from previous work. It includes unique contributions, new methods, or findings that have not been explored before in the field.]]>
