Empowering Rural Women: Earthworm Cultivation and Technology-Based Marketing presents an inspiring journey of how women in Indonesian villages transform challenges into opportunities through community-based entrepreneurship. This book highlights the story of Kelompok Wanita Tani (Women Farmers' Group) Mekar Tani in Cibodas Village, who pioneered the cultivation of earthworms (Lumbricus rubellus) not only to produce organic fertilizer (kascing), but also to develop high-value derivative products such as earthworm powder and capsules.By combining traditional practices with applied technology, the program demonstrates how rural women can elevate household income, strengthen local economies, and embrace sustainable practices. The narrative goes beyond agriculture-it integrates applied microbiology, eco-friendly innovation, and digital marketing strategies, enabling rural communities to access wider markets through e-commerce and social media platforms.The book provides a practical yet research-based framework for empowerment: from community mobilization, technical training, and mentoring, to product innovation, branding, and evaluation of economic impact. Rich with case studies, lessons learned, and reflections from the field, it offers insights for academics, practitioners, NGOs, and policymakers who seek to foster women's leadership in rural development.This work ultimately emphasizes that empowering women is not only about economic independence, but also about building resilience, solidarity, and long-term sustainability in rural communities. It is a valuable reference for those who believe that small-scale innovations can spark big changes in society.
