Semarang — Universitas Negeri Semarang (UNNES) has an institutional environmental management framework that supports efforts to minimise alterations to aquatic ecosystems associated with campus activities. Its approach connects Green Campus planning with wastewater treatment, hazardous-waste segregation, and laboratory safety practices intended to prevent contaminants from reaching receiving waters.
Institutional Planning for Environmental Protection
Rector’s Regulation No. 127 of 2024 on Green Campus Management Guidelines, established on 31 October 2024, provides the university’s planning framework. It covers green open spaces, waste management, water conservation, transportation, and campus land and building management.
The regulation assigns environmental management to the university unit responsible for conservation and provides for periodic monitoring and evaluation. These provisions establish a basis for coordinating campus activities that can affect water resources and surrounding ecosystems.
The framework supports pollution prevention and responsible land and water management. Its relevance to aquatic ecosystem protection lies in managing potential pressures before they reach water bodies.
Wastewater Treatment at FMIPA
A faculty-level example is documented in FMIPA UNNES’s report published on 2 September 2025. The faculty operates two wastewater treatment plants (WWTPs) serving its activities, including laboratory practical work and research.
Wastewater is collected and directed to treatment according to its characteristics. This arrangement is intended to prevent untreated laboratory wastewater from being released directly into the environment.
Hazardous-Waste Segregation and Safe Handling
Alongside wastewater treatment, FMIPA separates hazardous and toxic waste from ordinary waste streams. Waste requiring specialised handling is segregated and stored in designated facilities. Material not treated or utilised internally is transferred to authorised third-party providers, with packaging, labelling, documentation, transportation, and tracking.
Laboratory technicians also receive training in chemical handling, waste management, personal protective equipment, and emergency response. These practices address potential contamination risks at their source.
Minimising Potential Changes to Aquatic Environments
The documented measures are most directly relevant to minimising chemical alterations arising from laboratory waste and wastewater. The wider Green Campus framework also addresses land, water, and waste management, providing a planning basis for reducing environmental pressures.
The available evidence establishes institutional guidance and selected implementation at FMIPA. It does not identify a dedicated aquatic-ecosystem management plan covering all physical, chemical, and biological alterations, or publish measurements demonstrating ecosystem-wide outcomes. The documented approach therefore supports prevention of potential alterations, with its clearest operational evidence in wastewater treatment and hazardous-waste management.
