Determining the Efficiency Value of Reed Irrigation Channels in the Sungnak River Area of Pegajahan District, Serdang Bedagai Regency

Introduction

The efficiency of irrigation water distribution is a crucial factor in determining the effectiveness of water flows into agricultural land. In the Buluh Irrigation Area located in Pegajahan District, Serdang Bedagai Regency, a study revealed that the efficiency of water distribution only reached 36.22%. This figure is produced from the efficiency analysis of primary, secondary, and tertiary channels, each of which has an efficiency of 80.21%, 74.46%, and 60.64%, respectively. This article aims to discuss the analysis of irrigation channel efficiency, water loss, and provide conclusions and recommendations for improving the irrigation system in the reed area.

Analysis of Irrigation Channel Efficiency

To understand more about the efficiency of water distribution, it is essential to analyze each irrigation channel separately. The primary channel, which has the highest efficiency, functions as the main link between water sources and secondary channels. The primary channel's efficiency of 80.21% indicates a good design and maintenance, and is able to reduce water loss due to seepage. This suggests that the primary channel has a well-designed infrastructure and is managed effectively, resulting in minimal water loss.

On the other hand, the secondary channel, with an efficiency of 74.46%, shows that although there is a decrease in efficiency, there is still a fairly good management. However, there are challenges in reducing water lost due to environmental and environmental influences. The secondary channel's lower efficiency highlights the need for improved management practices and infrastructure design to reduce water loss.

Meanwhile, the tertiary channel, with an efficiency of 60.64%, shows that there are many factors that affect water loss, including physical factors and channel design. This is important, because the tertiary channel is the last channel before the water reaches agricultural land. With this lower efficiency, the water that reaches agricultural land is decreasing, which can have an impact on the harvest. The tertiary channel's low efficiency emphasizes the need for improved channel design and management practices to reduce water loss and ensure adequate water supply to agricultural land.

Water Loss: Source of Problem

The results also recorded several components of water loss, including seepage, percolation, and evaporation. In this case, the loss of water due to the seepage of the primary channel reaches 0.0347 liters per second, the secondary channel is 0.0187 liters per second, and the tertiary channel is 0.0009 liters per second. In addition, water loss due to percolation was recorded at 4.00 mm per day, while evaporation reached 1,158 mm per day. The significant water loss highlights the importance of conservation and improvement of irrigation systems to reduce water loss and ensure efficient water distribution.

Conclusions and Recommendations

With a relatively low distribution efficiency, there is an urgent need to improve the irrigation system in the reed area. Recommendations include improving channel infrastructure, farmers' training in effective irrigation management, and the use of technology that can monitor and reduce water loss. Improving the irrigation system will not only increase agricultural output but also support food security in the Serdang Bedagai Regency.

Through these efforts, it is expected that the efficiency of water distribution can increase, which in turn will increase agricultural output and the sustainability of water resources in the region. Better management is not only beneficial for farmers but will also support food security in the Serdang Bedagai Regency.

Future Directions

To improve the irrigation system in the reed area, the following future directions can be considered:

Conducting a thorough assessment of the irrigation system to identify areas of improvement
Implementing new technologies and management practices to reduce water loss and improve efficiency
Providing training and education to farmers on effective irrigation management practices
Improving channel infrastructure to reduce water loss and ensure adequate water supply to agricultural land

By implementing these recommendations and future directions, it is expected that the efficiency of water distribution can increase, resulting in improved agricultural output and food security in the Serdang Bedagai Regency.
