Food security remains a critical issue in Indonesia, heavily reliant on a deep understanding of plant pathology—a field focused on diagnosing and managing plant diseases, especially in essential crops. The Haryono Semangun Award (HSA) 2024, themed “Plant Pathology as the Foundation for Food Security in the Era 5.0”, aims to introduce plant pathology to a broader audience. The event honors the late Prof. Dr. Ir. Haryono Semangun, an esteemed Professor of Plant Pathology at UGM, whose contributions to the field remain an enduring inspiration.
