Evaluation Of The Pusong Reservoir As An Effort To Control Floods In The City Of Lhokseumawe North Aceh Regency

Understanding the Complexity of Floods in Lhokseumawe and North Aceh Regency

Floods are a recurring disaster that often hits the city of Lhokseumawe and North Aceh Regency, causing significant damage to properties, infrastructure, and the environment. The problem of floods is complex and involves various factors, such as changes in land use, which results in an increase in flood discharge, narrowing and siltation of channels due to settlement and sedimentation construction, as well as waste problems that clog water channels. Overcoming floods is a top priority and requires serious attention from local governments.

The city of Lhokseumawe and North Aceh Regency is prone to floods due to its geographical location, which is situated in a low-lying area near the coast. The region experiences heavy rainfall during the monsoon season, which can cause the water level to rise and overflow into the surrounding areas. The lack of effective flood control measures has exacerbated the problem, leading to frequent and severe flooding.

The Role of Pusong Reservoir in Flood Control

One of the efforts to control floods in Lhokseumawe and North Aceh Regency was the construction of the Pusong Reservoir. The reservoir was built to collect and store excess water during heavy rainfall events, reducing the risk of flooding in the surrounding areas. To evaluate the effectiveness of the Pusong Reservoir, this research was conducted by collecting secondary data from various related agencies, such as rainfall data, climate data, reservoir reservoir data, and technical drawings.

The data was then analyzed using the hydrological method to calculate the reservoir capacity. The analysis showed that the Pusong Reservoir has a fairly large storage capacity, reaching 850,000 m³, while the maximum discharge that enters the reservoir is 470,910 m³. The evaluation also showed that drainage in areas that are often affected by floods can still hold incoming water. The average capacity of the existing drainage discharge reaches 2,657 m³/sec, while the maximum drainage plan discharge is 1,162 m³/sec.

Analysis of Flood Discharges Annual Birthday Plans

To get accurate results, some statistical distribution methods were applied, such as normal distribution, normal log distribution, Pearson III log distribution, and gumbel distribution. The analysis of flood discharges annual birthday plans using rainfall data from the Lhokseumawe City Meteorology Agency showed that the Pusong Reservoir is able to collect incoming water, both from the drainage flow and direct rainfall.

The results of the evaluation showed that the Pusong Reservoir is effective in reducing the risk of flooding in the city of Lhokseumawe and North Aceh Regency. The reservoir has a fairly large storage capacity and can accommodate high flood discharge. Drainage in flood-prone areas also has adequate capacity to accommodate incoming water.

Analysis and Conclusion

Based on the evaluation results, the Pusong Reservoir proved effective in reducing the risk of flooding in the city of Lhokseumawe and North Aceh Regency. The reservoir has a fairly large storage capacity and can accommodate high flood discharge. Drainage in flood-prone areas also has adequate capacity to accommodate incoming water.

However, the evaluation also showed that there are still some limitations and challenges that need to be addressed. The Pusong Reservoir is not a standalone solution to the problem of floods, and it requires a combination of other measures to be effective. The local government and other stakeholders need to work together to improve the drainage system, increase public awareness about the importance of maintaining environmental cleanliness and waterways, and minimize careless disposal.

Recommendation

Although the Pusong Reservoir is proven to be effective, further efforts need to be made to increase their effectiveness in controlling floods:

*** Increasing public awareness: Community education about the importance of maintaining environmental cleanliness and waterways and minimizing careless disposal.***

*** Drainage system improvement: It is necessary to improve and maintain the drainage system regularly, including cleaning channels from waste and sedimentation.***

*** Land Use Development: Application of appropriate and sustainable land use to reduce the impact of land use changes on flood discharge.***

With a combination of the Pusong Reservoir and additional efforts, it is expected to create a more effective and sustainable flood control system in Lhokseumawe City and North Aceh Regency.

Conclusion

The evaluation of the Pusong Reservoir as an effort to control floods in the city of Lhokseumawe and North Aceh Regency has shown that the reservoir is effective in reducing the risk of flooding. However, it is not a standalone solution, and it requires a combination of other measures to be effective. The local government and other stakeholders need to work together to improve the drainage system, increase public awareness, and minimize careless disposal. With a combination of the Pusong Reservoir and additional efforts, it is expected to create a more effective and sustainable flood control system in Lhokseumawe City and North Aceh Regency.

Q: What is the Pusong Reservoir and how does it help in flood control?

A: The Pusong Reservoir is a water storage facility built to collect and store excess water during heavy rainfall events, reducing the risk of flooding in the surrounding areas. It has a fairly large storage capacity, reaching 850,000 m³, and can accommodate high flood discharge.

Q: How does the Pusong Reservoir work?

A: The Pusong Reservoir works by collecting incoming water from the drainage flow and direct rainfall. The water is then stored in the reservoir, reducing the risk of flooding in the surrounding areas. The reservoir also helps to regulate the water level, preventing it from overflowing into the surrounding areas.

Q: What are the benefits of the Pusong Reservoir in flood control?

A: The Pusong Reservoir has several benefits in flood control, including:

• Reducing the risk of flooding in the surrounding areas
• Regulating the water level, preventing it from overflowing into the surrounding areas
• Providing a safe and controlled environment for water to flow into the reservoir
• Helping to prevent damage to properties and infrastructure

Q: What are the limitations of the Pusong Reservoir in flood control?

A: The Pusong Reservoir has several limitations in flood control, including:

• It is not a standalone solution to the problem of floods
• It requires a combination of other measures to be effective
• It may not be able to handle extreme weather events or high flood discharge
• It requires regular maintenance and upkeep to ensure its effectiveness

Q: What can be done to improve the effectiveness of the Pusong Reservoir in flood control?

A: To improve the effectiveness of the Pusong Reservoir in flood control, the following measures can be taken:

• Increasing public awareness about the importance of maintaining environmental cleanliness and waterways
• Improving and maintaining the drainage system regularly
• Minimizing careless disposal and waste management
• Applying appropriate and sustainable land use to reduce the impact of land use changes on flood discharge

Q: What is the role of the local government in flood control?

A: The local government plays a crucial role in flood control, including:

• Providing funding and resources for flood control measures
• Implementing policies and regulations to prevent flooding
• Educating the public about the importance of flood control and the role they can play in preventing flooding
• Collaborating with other stakeholders to improve the effectiveness of flood control measures

Q: What can individuals do to help in flood control?

A: Individuals can play a crucial role in flood control by:

• Maintaining environmental cleanliness and waterways
