Introduction

The Lau Simme Dam, located in Sibiru-Biru District, Deli Serdang Regency, plays a vital role in supporting various community needs. This dam serves as a flood controller, clean water provider, and an electrical energy source through a hydroelectric power plant (PLTA). The importance of the existence of the Lau Simme Dam has led to a potential study to optimize the use of water resources that entered the reservoir.

Methodology

This study analyzed rainfall data for 12 years, river flow debit for 7 years, a map of watersheds (DAS), and reservoir characteristics. Flood discharge analysis using the HSS Nakayasu method shows that the maximum flood discharge of the 1000-year repellent period reaches 840,606 m3/s. Through flood routing analysis, the maximum discharge that passes through an abundance of 761,961 m3/s in elevation of 250,229 m, with a height of freeboard 3,271 m. This shows that the Lau Simme Dam is safe from the danger of runoff due to the maximum flood discharge of 1000 years.

Results

Analysis of river availability shows that inflow debit averages 5.01 m3/s based on the calculation of the Tembung-Percut Awlr River discharge, and 4.76 m3/s based on the calculation of the F.J. discharge calculation. Mock. The need for clean water is set at 4,6839 m3/s, while river flush is 10% of the average debit, which is 0.5 m3/s. The Lau Simme Dam has only one water-taking inlet for hydropower, which is also a source of clean water. Potential hydropower reaching 2.1 MW, with electrical energy up to 18396 MWH.

Discussion

Based on the calculation of the potential of the reservoir using mass curve, the ideal reservoir storage volume to meet all requests is 88.431 million m3. However, based on the relationship between the area of water level, volume, and elevation, the Lau Simme Dam reservoir only reached 21.07 million m3.

Conclusion

This study shows that the Lau Simme Dam has great potential in supporting the needs of clean water, flood control, and electrical energy in Deli Serdang Regency. However, limited dam reservoir capacity is an obstacle in achieving its optimal potential.

Recommendations

Optimization of Reservoirs

It is necessary to increase the capacity of the dam reservoir, for example by building additional dams or revitalizing the existing dam structure.

Utilization of Runoff Water

Redimp water can be processed and used for other purposes, such as irrigation, animal husbandry, or to increase groundwater reservoir capacity.

Increased Efficiency

Increased efficiency in the use of clean water and electrical energy can be done through community education programs and the application of water and energy saving technology.

The Importance of Collaboration

A strong collaboration between local governments, academics, and the community is needed in managing and utilizing the potential of the Lau Simme Dam. With a solid collaboration, the potential for water resources can be maximized for the welfare of the community and the progress of Deli Serdang Regency.

Positive Impact

The optimal utilization of the Lau Simme Dam will have a broad positive impact on Deli Serdang Regency, including:

Flood Control

Reducing the risk of flooding and protecting the community from natural disasters.

Availability of Clean Water

Ensuring access to clean water for the community and encourage improving the quality of life.

Clean Energy Source

Providing clean and sustainable electrical energy, reducing dependence on fossil energy.

Economic Development

Opening opportunities for economic development in the agricultural, tourism, and industrial sectors.

Future Challenges

Utilization of the potential of the Lau Simme Dam is also faced with several challenges, such as:

Climate Change

Increased intensity and frequency of extreme rain can threaten dam resistance.

Water Pollution

Human activity can pollute water sources and threaten the quality of clean water.

Changes in Land Use

Changes in land use around the watershed can affect the flow of water and dam storage capacity.

Final Conclusion

Lau Simme Dam has great potential to be a multipurpose solution for Deli Serdang Regency. Through optimal management and solid collaboration, this potential can be maximized to improve the welfare of the community and regional development. It is important to continue to monitor the condition of the dam, overcome the challenges that exist, and ensure the sustainability of the use of water resources.
