The Faculty of Science and Mathematics (FSM) at Universitas Diponegoro, through the Cluster for Paleolimnology (CPALIM), played an active role in the World Lakes Day commemoration and the National Coordination Meeting (Rakornas) “Evaluation of the Preservation of 15 Priority National Lakes and Their Future Development,” held on October 1, 2025, at the Westin Hotel Jakarta. This event was attended by various parties involved in the preservation and management of priority lakes in Indonesia.
In his opening speech, Minister of Environment and Forestry (KLHK) Hanif Faisol Nurofiq emphasized the importance of efforts to preserve the 15 priority national lakes. He stated, “The preservation of these 15 priority lakes is our main focus. We will continue to work hard to achieve the targets set, although there are many challenges, such as sedimentation and invasive species.”
Following the speech, the event continued with a scientific presentation by Prof. Dr. Tri Retnaningsih Soeprobowati, M.AppSc, Head of CPALIM and Professor in the Department of Biology at FSM UNDIP. In her presentation, Prof. Soeprobowati discussed the significant challenges in lake management, including the proliferation of water hyacinth, which can cover one square meter of the lake in just 28 days. She also highlighted the ongoing issue of increasing sedimentation, which threatens water volume and the carrying capacity of the lakes.
Prof. Soeprobowati stressed the importance of applying the Integrated Lake Management (ILM) concept, which combines ecological, social, and economic factors, and involves collaboration between the government, communities, and the private sector. According to her, holistic lake management based on scientific data is key to the long-term sustainability of lake ecosystems.
The World Lakes Day commemoration and Rakornas also served as an important moment for the government and relevant parties to evaluate the achievements and challenges in the preservation of the 15 priority lakes and to formulate concrete steps for the future.
FSM UNDIP, through CPALIM, continues to support scientific efforts aimed at maintaining the sustainability of Indonesia’s lakes and remains committed to contributing research and science-based solutions for environmental conservation.
