Introduction

Importance of Embung Seifulu in Central Simeulue Regency, Aceh

Embung Seifulu in Central Simeulue Regency, Aceh, is a vital asset in the region's effort to increase agricultural production. This reservoir has an area of 800 hectares and is capable of serving irrigation for 60 hectares of land. However, with the increasing demands of agricultural production, the availability of irrigation water becomes a significant challenge, especially during the dry season. Therefore, the evaluation of the reservoir capacity is crucial to ensure that irrigation water needs are met and the harvest remains optimal.

Background of the Study

The region of Central Simeulue Regency, Aceh, is known for its fertile soil and favorable climate, making it an ideal location for agricultural activities. However, the region's agricultural production is heavily reliant on the availability of irrigation water. Embung Seifulu, with its capacity to serve irrigation for 60 hectares of land, plays a vital role in meeting the irrigation needs of the region. However, with the increasing demands of agricultural production, the reservoir's capacity to meet irrigation needs is being put to the test.

Analyzing Irrigation Water Needs

Methodology

This research was conducted by collecting secondary data such as rainfall, climate, and technical drawings from related agencies. Rainfall data were analyzed using the Thiessen polygon method with data from two rain-gauge stations for 10 years. Analysis of irrigation water needs considers important factors such as effective rainfall, mainstay discharge, and evapotranspiration.

Factors Affecting Irrigation Water Needs

Effective rainfall, mainstay discharge, and evapotranspiration are crucial factors that affect irrigation water needs. Effective rainfall refers to the amount of rainfall that is available for irrigation, while mainstay discharge refers to the amount of water that is discharged from the reservoir. Evapotranspiration, on the other hand, refers to the amount of water that is lost through evaporation and transpiration.

Analysis and Simulation Methods of Planting Patterns

Methodology

To simulate the needs of irrigation water, this study examines 24 alternative planting periods in one year, with a focus on the planting pattern of rice-paddy-palawija. This analysis was carried out to determine the most efficient ideal irrigation water needs and planting patterns.

Planting Patterns and Irrigation Water Needs

The study found that the most efficient ideal irrigation water needs and planting patterns vary depending on the planting period. The study recommends that farmers adopt a planting pattern that takes into account the irrigation water needs of the crop. For example, rice-paddy-palawija planting pattern is recommended for the dry season, while other planting patterns are recommended for the wet season.

Evaluation Results of Seifulu Embung Capacity

Results

Based on the results of the analysis, the smallest NFR (Net Flow Requirement) value was 1.77 mm/day, with an alternative planting pattern, with the beginning of the planting period in the October II period. This shows that the seifulu reservoir has the potential to meet irrigation needs with a reservoir capacity of 52,810,763 m³.

Implications of the Results

The results of the study have significant implications for the management of Embung Seifulu. The study recommends that the reservoir's capacity be increased to meet the growing demands of agricultural production. Additionally, the study recommends that the irrigation system be improved to minimize water loss due to evaporation and increase the efficiency of water use.

Recommendations and Application of Research Results

Recommendations

This study provides important recommendations for optimizing the utilization of seifulu reservoirs, namely:

Increasing the Efficiency of Irrigation Systems

Implementation of efficient irrigation systems such as drops or sprinkler irrigation systems can help minimize water loss due to evaporation and increase the efficiency of water use.

Water Monitoring and Management

Periodic monitoring of flow discharge, rainfall, and reservoir conditions are very important to maintain water availability and minimize drought risk.

Socialization and Education

Socialization to farmers regarding the importance of the efficiency of water use and appropriate cultivation methods can help improve crop yields and maintain the sustainability of water resources.

Conclusion

Evaluation of Seifulu Embung capacity shows that this reservoir has the potential to meet irrigation needs in the Seifulu Village area. With the application of appropriate strategies and recommendations, this reservoir can be a key factor in increasing agricultural production and community welfare in Central Simeulue Regency, Aceh.

Future Research Directions

Future research should focus on improving the efficiency of irrigation systems, increasing the capacity of the reservoir, and implementing water monitoring and management systems. Additionally, research should be conducted on the social and economic impacts of the study's recommendations on the community.

Limitations of the Study

The study has several limitations, including the reliance on secondary data and the assumption of a fixed reservoir capacity. Future research should aim to address these limitations and provide a more comprehensive understanding of the Embung Seifulu's capacity to meet irrigation needs.

Contribution of the Study

The study contributes to the body of knowledge on the management of Embung Seifulu and provides important recommendations for optimizing the utilization of the reservoir. The study's findings have significant implications for the management of water resources in the region and can be applied to other similar reservoirs in the region.
