Introduction

Langsa City, located in Indonesia, has been experiencing rapid development in recent years. This growth has led to an increase in economic activities, including trade and industry, which in turn has resulted in a significant increase in population and infrastructure development. However, this growth has also brought about new challenges, including the issue of flooding due to rainfall. The city's drainage system is a crucial element in preventing flooding and maintaining the smooth operation of economic activities. This study focuses on the drainage system in the Sudirman Ujung road area, which is the center of economic activity and has a lower basic channel elevation compared to the estuary channel.

Background of the Study

Langsa City is a rapidly developing city in Indonesia, with a growing economy and increasing population. The city's drainage system is a critical component in preventing flooding and maintaining the smooth operation of economic activities. However, the existing drainage system in the Sudirman Ujung road area is unable to accommodate the discharge of peak floods, resulting in frequent flooding and standing water. This study aims to investigate the drainage system in the Sudirman Ujung road area and identify solutions to mitigate the problem of flooding.

Methodology

The methodology used in this study includes determining research objects and restrictions, types of research, and data collection and analysis. To estimate the amount of rainfall, the Pearson type III log distribution method is used, which aims to calculate the peak flood discharge with a certain period of repeat. The results showed that the existing drainage discharge (Q) in the area around Jalan Sudirman Ujung was smaller than the Puncak flood discharge (QP). This indicates that the current drainage system is unable to accommodate the discharge of peak floods.

Problem Statement

The problem of flooding and standing water around Jalan Sudirman Ujung is a significant issue that affects the community and the local economy. The existing drainage system is unable to accommodate the discharge of peak floods, resulting in frequent flooding and standing water. This study aims to identify solutions to mitigate the problem of flooding and improve the drainage system in the Sudirman Ujung road area.

Impact Analysis and Solution

Adequate drainage infrastructure development is very important to ensure the continuity of economic activity that takes place in the region. Lack of drainage system capacity can cause negative impacts, such as an increase in the risk of floods that not only harm the community but also have an impact on the local economy.

Channel Normalization

Normalization of channels not only serves to regulate water flow, but also to prevent sedimentation that can inhibit flow. This process involves measurement and in-depth analysis of the characteristics of existing channels. By doing proper normalization, it is expected that channels can drain water faster and more efficiently.

Increased Channel Dimensions

The addition of channel dimensions is one of the effective solutions. With a larger channel width, water reservoirs can increase, thus minimizing the possibility of inundation. However, it should be remembered that an increase in channel dimensions must be done by paying attention to environmental aspects and potential negative impacts on the surrounding ecosystem.

The Construction of Infiltration Ponds

The construction of infiltration ponds is a sustainable alternative that not only reduces the risk of flooding, but also functions as a way to improve groundwater quality. This pool will help absorb rain water, thereby reducing the run-off rate and strengthening groundwater reserves.

Conclusion

An effective and efficient drainage system is needed to support economic growth in the city of Langsa, especially in the Sudirman Ujung road area. By implementing channel normalization strategies, improving channel dimensions, and the construction of infiltration ponds, it is expected that flood problems can be minimized. This effort will not only improve the quality of life of the community, but also creates a safer and more comfortable environment for economic activities.

Recommendations

Based on the findings of this study, the following recommendations are made:

Normalization of Channels: Regulate the slope of the channel and make improvements to the main channel embankment to increase the water flow capacity.
Increased Channel Dimensions: Enlarge the width of the channel from 4 meters to 7 meters to increase the capacity of the water reservoir.
Construction of Infiltration Ponds: Build infiltration ponds in urban areas to accommodate rainflow. This infiltration pond serves to reduce the run-off rate and support water infiltration into the groundwater system.

By implementing these recommendations, it is expected that the drainage system in the Sudirman Ujung road area can be improved, and the problem of flooding can be minimized. This will not only improve the quality of life of the community, but also create a safer and more comfortable environment for economic activities.
