Hasanuddin University has demonstrated a strong commitment to water quality management and pollution prevention. Through a Rector’s Circular Letter and a Rector’s Decree on the Guidelines for Efficient and Sustainable Water Management at Hasanuddin University, the institution ensures the efficient use of water resources while maintaining the sustainability of the campus ecosystem. These guidelines set out measures for protecting and preventing both water and land environments from pollution within the campus area. They include the management of liquid waste, water quality monitoring, and the application of environmentally friendly technologies to safeguard ecosystems and public health.

 

These efforts are further strengthened through research and monitoring of the water quality of the Unhas Campus Lake, which serves both as a water tourism area and a scientific park. Research findings indicate that the lake water is currently classified as slightly to moderately polluted, thus requiring integrated management. This includes adding biological indicators, increasing vegetation diversity around the lake, and coordinating management efforts with nearby residential areas.

 

Unhas students have also carried out concrete initiatives. For example, through the Thematic Community Service Program (KKNT) in Tamaona Village, students introduced the Electrical Resistivity Tomography (ERT) method to determine the distribution of clean water, thereby making stunting prevention efforts more effective. In addition, AIESEC Unhas students educated elementary school pupils about water filter technology, raising awareness and understanding of the importance of water quality. Another innovation involves utilizing corncob waste as a water purifier material, which simultaneously reduces organic waste and supports environmental sustainability.

Hasanuddin University actively implements a plastic waste reduction policy within the campus environment. One of the main policies is the Circular Letter on the Prohibition of Single-Use Drinking Water Packaging and Plastic Bags No. 09246/UN4.1/KM.01.03/2024 and the Circular Letter on the Use of Tumblers No. 05501/UN4.16/PL.04/2024, which require all members of the academic community to reduce single-use plastic consumption across all campus units and facilities. This policy is further supported by the Circular Letter on the Protection and Prevention of Water and Land Pollution No. 28720/UN4.1/KM.01.03/2024 and the Rector’s Regulation on the Guidelines for Spatial and Building Management of the Campus No. 11/UN4.1/2022, emphasizing the principles of reduce, reuse, recycle, environmentally friendly waste management, and plastic pollution prevention.

 

In addition to formal policies, Unhas students have initiated various plastic waste reduction and management programs, including:

  1. Waste Bank and Recycling Education Programs: Students from the Faculty of Forestry and the Faculty of Public Health manage a campus waste bank, educating the academic community and local residents on waste sorting, recycling into ecobricks, and producing organic fertilizer(forestry.unhas.ac.id;unhas.tv; identitasunhas.com).
  2. Plastic Waste Utilization into Useful Products: Students participating in thematic community service programs (KKN) transform plastic waste into paving blocks and educate village communities on environmental awareness (warnasulsel.com; putraindonews.com).
  3. Microplastic and Food Packaging Safety Education: Public Health students educate housewives about the dangers of microplastics in household products and the safety of food packaging (potretnusantara.co.id; mediasulsel.com).
  4. Innovative Waste Management and Incentive Programs: Students organize programs such as exchanging waste for mobile credit and implementing waste sorting in schools to support a green campus (sulselsatu.com; fkm.unhas.ac.id).
  5. Recycling and Ecobrick Education in Schools and Communities: The Center for Environmental Studies and Unhas students from the Faculty of Public Health conduct recycling education programs to turn plastic waste into ecobricks, along with waste management demonstrations in Bonto-Bonto Village (identitasunhas.com; suluhnusantara.id).

 

Through the combination of formal policies and student-led initiatives, Hasanuddin University has successfully reduced plastic usage on campus, increased community awareness of sustainable waste management, and supported the preservation of terrestrial ecosystems.

Hasanuddin University has a clear and systematic policy for the management and disposal of Hazardous and Toxic Materials (B3) waste. This policy includes:

  1. Rector’s Decree on Guidelines for Efficient and Sustainable Wastewater Management within Hasanuddin University No. 04061/UN4.1/KEP/2024
    This decree provides a framework for managing wastewater efficiently and sustainably across the university.
  2. Circular Letter on the Disposal of Hazardous and Toxic Materials (B3) Waste No. 13826/UN4.1/RT.03.01/2024 

This circular regulates the identification, segregation, storage, and disposal of B3 waste within the campus environment. It also establishes the procedures that all members of the Unhas academic community must follow to ensure safe and compliant B3 waste management in accordance with existing laws and regulations.

  1. Rector’s Regulation on Guidelines for Campus Spatial and Building Management No. 11/UH4.1/2022
    This regulation emphasizes the importance of environmentally friendly management of campus spaces and buildings, including the management of B3 waste. It covers the organization of temporary storage facilities for B3 waste and the establishment of standard operating procedures (SOPs) for its handling.
  2. Cooperation Agreement on the Transportation and Destruction of B3 Waste by the Faculty of Pharmacy No. 1128/UN4.17/HK.07.00/2022
    The Faculty of Pharmacy has established a partnership with a licensed third party authorized to transport and destroy B3 waste. This agreement ensures that all B3 waste produced by the faculty is handled safely and in compliance with the standards set by the Ministry of Environment and Forestry (KLHK).
  3. Research Documents on B3 Waste Management:
    Research conducted by Unhas students provides recommendations on B3 waste management, including waste type identification, storage methods, and appropriate disposal procedures. These studies serve as a foundation for developing policies and best practices for B3 waste management at Unhas.

Through these policies and practices, Hasanuddin University is committed to managing B3 waste responsibly, minimizing negative environmental impacts, and supporting the preservation of terrestrial ecosystems.
