Students from SMA Negeri 2 Cilacap in Central Java have earned a silver medal at the 2026 National Student Science Fair (JNSF) for their innovative project transforming discarded banana stems into natural soap.
The project, led by a team of students at the public high school in Cilacap regency, focused on repurposing agricultural waste from banana cultivation into an eco-friendly cleansing product. By processing the fibrous stalks—typically discarded after harvest—the students developed a biodegradable soap that reduces environmental waste while offering a sustainable alternative to conventional hygiene products.
Their work highlights the potential of local, renewable resources in addressing both waste management and personal care needs. According to the school, the innovation aligns with broader efforts to promote environmental stewardship and practical science education among students.
The silver medal recognizes the team’s scientific rigor, creativity, and application of STEM principles to real-world challenges. The achievement reflects the school’s commitment to fostering student innovation in health, sustainability, and community-focused solutions.
This accomplishment adds to a growing record of academic excellence at SMA Negeri 2 Cilacap, which has previously seen students advance to national competitions in science and technology. The banana stem soap project exemplifies how grassroots innovation can contribute to public health and ecological resilience using readily available materials.
