The suboptimal management of coffee waste affected a significant challenge because the coffee waste is often discarded without being utilized optimally. As a long-term impact, this can cause environmental pollution and loss of economic opportunities from coffee waste. A similar case occurred in the Cikamiri Sub Watershed, Garut, West Java. So it needed to be carried out by applying coffee waste to potential products such as cascara tea, liquid organic fertilizer, and bio-briquettes, but the product priority is not yet known. So that, this study aims to determine the priority for processing coffee waste into high-value products, such as cascara tea, liquid organic fertilizer (POC), and bio-briquettes using the Analytic Hierarchy Process (AHP) method in the Sub DAS Cikamiri, Garut, West Java. AHP was chosen for its ability to handle multi-criteria decision-making in a structured manner. The criteria used in this study include labor availability, investment cost, high market value, and material availability. The result showed that cascara tea (prevalence value of 68.6%) was the highest-priority product, followed by liquid organic fertilizer (prevalence value of 20.7%) and bio-briquettes (prevalence value of 10.6%). This study indicated that cascara tea had high market potential, while liquid organic fertilizer and bio-briquettes can be developed by considering environmental impact and sustainability. This research provides strategic recommendations to optimize coffee waste utilization, focusing primarily on cascara tea production to enhance economic value and positive environmental impacts. Keywords: analytical hierarchy process, bio-briquettes, cascara, coffee waste, liquid organic fertilizer

Local communities have ways of managing and utilizing forest products, including leopard cats' habitat. Communities have knowledge and perceptions passed down from one generation to the next through community participation in their environment. This activity aims to reveal the community's knowledge regarding the role of leopard cats in the Cisokan. The implementation of this activity consists of collecting issues and data, FGD, and evaluation. The results show that almost all informants do not know the role of leopard cats in controlling prey animal populations and agricultural pests. Although leopard cats prey on domestic birds, they are not considered a nuisance to the community. After a joint discussion with the community regarding the ecological role of leopard cats, 79% of informants understood leopard cats' role in nature, which indirectly supported agriculture. Besides that, 70% of respondents understand that leopard cats should be protected.
