Deli River Water Quality Prediction Model as a Source of Clean Water in Medan City

Introduction

The Deli River, flowing through the heart of Medan, is a vital source of clean water for the people of the city. As a manager of water resources, the Regional Water Supply Company (PDAM) utilizes the Deli River as one of the primary sources of drinking water. However, predicting the quality of the Deli River water is crucial in managing this river as a sustainable source of clean water. This study focuses on developing a mathematical model to predict changes in water quality due to variations in waste flow, particularly in limited data scenarios.

Background

The Deli River, approximately 7 km long, is part of the Belawan River Tahai-Cultural Group in North Sumatra Province, Indonesia. As a vital source of clean water, the Deli River plays a significant role in supporting the daily needs of the Medan community. The importance of predicting the quality of the Deli River water cannot be overstated, especially in an effort to manage this river as a source of drinking water in a professional and sustainable manner.

Methodology

The simplified river water quality model has been formulated based on conceptual hydraulic sub-models and simplification of the existing river water quality model. In dynamic modeling, the tank reactor is perfectly mixed (CSTR) that is connected in series is assumed to represent river flow behavior. Each reactor functions as a computing element that is interconnected in sequence with similar elements upstream and downstream. The results of this model were successfully applied to predict the water quality of the Deli River.

Results

Through sensitivity analysis, the results show that this model is effective in predicting the quality of the Deli River water, especially in determining the concentration of dissolved oxygen (DO). The model's ability to accurately predict water quality changes due to variations in waste flow makes it a valuable tool for PDAMs in planning and managing water resources.

Planning Drinking Water Resources

In planning drinking water resources, linear regression is used to analyze the relationship between clean water flow and the level of water consumption by the Medan community, as well as the Deli River water flow and the population in the city. Basically, the level of water consumption is strongly influenced by the population. This shows that the increase in population results in an increase in the need for clean water. Therefore, planning the availability of drinking water is very important to do.

Challenges in Providing Clean Water

In the fast context of urbanization in the city of Medan, which is one of the largest cities in Indonesia, the challenges in providing clean water are increasing. High water consumption of the population that continues to develop can potentially increase river pollution, if not managed properly. Therefore, the application of the Water Quality Prediction Model as described earlier is very crucial.

Effective Models in Planning and Managing Water Resources

Effective models can help PDAMs in planning and managing water resources better. This is not only to guarantee adequate clean water supply, but also to maintain environmental sustainability. By accurately understanding changes in water quality, the government and related institutions can design better policies in managing waste and protection of water sources.

Community and Industrial Sector Involvement

In the development of this model, it is also important to involve the community and the industrial sector in the process of water quality control. Education on the impact of industrial waste on water quality and promotion of environmentally friendly practices can make a significant contribution in maintaining the cleanliness of the Deli River.

Conclusion

The Deli River water quality prediction model does not only function as an analytical tool, but also as a guide for creating effective policies for the sustainability of clean water sources in the city of Medan. Careful planning and collaboration between government, community, and industry will be the key to ensuring the availability of clean water for future generations.

Future Directions

The development of this model is expected to be used in integrated modeling between the quality of wastewater and river in the future. This will enable a more comprehensive understanding of the complex relationships between water quality, waste flow, and population growth. By incorporating the community and industrial sector in the process of water quality control, the model can be further improved to ensure the sustainability of clean water sources in the city of Medan.
