Good Manufacturing Practices (GMP) in community-based and smallholder patchouli oil production represents a positive initiative to enhance productivity and profitability while mitigating risks associated with workforces, workflows, and environment. This study aims to explore the implementation of GMP in a patchouli industry center run by community-based cooperative in Lhoong, Aceh Besar. This is a qualitative study which collect data from interviews and observations, and analyzes the data using comparative analysis. Data is classified according to the 5P indicators of GMP, which consists of products, people, processes, procedures, and premises. This study reveals that while GMP is generally unfamiliar to those in community-based and smallholder patchouli oil production, it's practices are already implemented in the knowledge of farmers and producers. However, there is a need for the community and smallholders to enhance their understanding and awareness of GMP, and actively participate in the training provided by stakeholders. The implementation of GMP promotes green technology initiatives to strengthen the sustainability of patchouli oil industry while fostering economic growth and improving community well-being. This study recommends the formation of a task force team within the community, trained to implement GMP perfectly in the patchouli oil industry center. Additionally, the findings of this study contribute to the goals of SDG 9 (Industry, Innovation, and Infrastructure) and SDG 12 (Responsible Consumption and Production).
