Abstract
The sustainability of eco-farming based on Arabica coffee in Sembalun, West Nusa Tenggara, Indonesia is influenced by various environmental, economic, social, cultural, institutional, and technological factors. Arabica coffee, known for its high quality, has become an important commodity for farmers and the local economy. However, challenges in implementing sustainable agricultural practices, such as excessive pesticide use and limited knowledge, hinder the adoption of eco-farming. This research adopts a combined qualitative and quantitative approach to evaluate the factors affecting sustainability. The results indicate that improvements in land management and waste disposal, educational and social support for farmers, as well as the active role of women farmer groups and community organizations, are crucial for achieving effective sustainability. It is hoped that these findings will provide practical recommendations to enhance eco-farming systems and support sustainable development goals, as well as the welfare of farmers in Sembalun.
