Universitas Diponegoro (UNDIP) is actively engaged in research and initiatives focused on monitoring the health of aquatic ecosystems, with several studies published or forthcoming in 2024–2025 through its journals. Key areas of focus include: River Health Assessment, where UNDIP researchers apply both biotic (biotilik) and physical observation methods, as demonstrated in the Boyong River assessment. Marine Ecosystem Monitoring explores chlorophyll-a indicators to evaluate marine ecosystem quality and human impact, alongside assessments of seagrass health in Eastern Indonesia. Technological Advancements feature the integration of IoT-based automated systems for real-time water quality monitoring (pH, turbidity, temperature). Pollution and Remediation Studies address mercury phytoremediation using aquatic plants and conduct bibliometric reviews of industrial pollution research. Community Involvement emphasizes participatory monitoring and environmental education to enhance local surveillance systems in island regions, demonstrating UNDIP’s commitment to sustainable aquatic ecosystem management.

The Department of Capture Fisheries (DPT) FPIK UNDIP carried out a community service activity in Pakis, Magelang, by introducing and training the practice of Fish Cultivation in Buckets (Budikdamber). The program aims to encourage good and sustainable aquatic stewardship practices at the household level, especially where land and water resources are limited. Through Budikdamber, the community receives incentives in the form of simple technology training to produce fish (catfish) and vegetables independently, which not only enhances local food security and economy but also reduces pressure on public aquatic resources and promotes environmentally friendly aquaculture.

The article summarizes a Collaboration activity between the UNDIP 2023 Thematic KKN-SDGs Team, the UNDIP IDBU Team, and the Local Community (including BUMDES) in Tambakbulusan Village, Demak. This collaboration focused on efforts to maintain shared aquatic ecosystems through the planting of 500 mangrove seedlings on Glagah Wangi Beach. This action utilized the guludan (demplot) technique and aimed to rehabilitate the coastal environment damaged by abrasion, while restoring the ecological function of mangroves. The activity affirms the university’s role in supporting sustainable development and coastal preservation through community service.

Universitas Diponegoro (UNDIP) is innovating mangrove nurseries using environmentally friendly technology in Tambakbulusan Village, Demak Regency. This innovation utilizes biodegradable polybags as a planting medium that can decompose naturally, replacing conventional plastic polybags that have the potential to pollute the environment. Through this program, UNDIP focuses not only on the technological aspect but also on empowering coastal communities by involving community groups and Village-Owned Enterprises (BUMDes) in mangrove nurseries and planting activities. This effort aligns with UNDIP’s commitment to supporting coastal ecosystem conservation, climate change mitigation, and the achievement of sustainable development goals (SDGs).
