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).

Growing demand for patchouli oil has undoubtedly become an opportunity for the patchouli industry, particularly in Aceh, which supplies about 80% of Indonesia’s patchouli oil in the global supply chain system. However, the opportunity is often misguided by farmers and even the government, which implements various programs related to patchouli cultivation without identifying the potential land that is suitable to be used for it. The condition indicated that not every land is suitable for patchouli cultivation. Thus, it is necessary to cluster the distribution of existing patchouli plantations. The clustering aims to identify the existing patchouli plantations that have the potential for replication. This study uses the K-Means method that combines variables (the planting land, the harvesting land, and total production) to provide information on the plantation’s potential scale in each region. The clustering measurement pointed out that the plantation in South Aceh Regency has the most potential land for sustainable cultivation, followed by several other areas included in Cluster 2 and Cluster 3. The study’s result is essential in contributing significantly to optimizing patchouli cultivation management sustainability to fulfill Aceh Province’s role as the best quality patchouli oil supplier.
