Run off Potential and Sedimentation in the Natural Drainage of the Mount Sinabung Eruption Refugee Settlement Area in Siosar Kapab Regency, Karo Regency

Introduction

The transformation of forest ecosystems into settlement and agriculture areas has resulted in various environmental changes, one of which is the increase in surface runoff and sedimentation. The conversion of land from forests to settlements has a significant impact on the environment, particularly in the context of the Mount Sinabung eruption refugee settlement area in Siosar Kapab Regency, Karo Regency. This study aims to investigate the potential surface flow and sedimentation in the natural drainage of the Mount Sinabung eruption refugee settlement area in Siosar, Karo Regency.

Background

The Mount Sinabung eruption in 2010 displaced thousands of people, who were forced to settle in the Siosar region, Karo Regency. The rapid transformation of forest ecosystems into settlement and agriculture areas has resulted in various environmental changes, including the increase in surface runoff and sedimentation. The conversion of land from forests to settlements has a direct impact on the ability of the soil to absorb water, which ultimately increases the amount of water flowing to the surface.

Methodology

This study uses a survey method with a comparison approach to watersheds (DAS) which have different land cover, namely forests, parts of forests, and settlements. In addition, topographic boundaries are also considered to estimate the potential of surface runoff. Primary data is collected through measurement of water discharge in the field and water quality analysis. Meanwhile, secondary data are taken from sources such as RBI digital maps, meteorological data, population statistics, and Siosar Forest History.

Results

The results of this study showed that the conversion of land from forests to settlements contributed to increasing surface flow and sedimentation discharge, especially during the rainy season. The existence of open land caused by deforestation has a direct impact on the ability of the soil in absorbing water, which ultimately increases the amount of water flowing to the surface. Water quality is also a concern in this study. In forest areas, water quality is relatively good due to vegetation that functions as a natural filter. Conversely, in residential areas, mild pollution occurs, which can be caused by domestic waste and other human activities.

Discussion

The results of this study highlight the importance of understanding the impact of land conversion on ecosystems. The conversion of land from forests to settlements has a significant impact on the environment, particularly in the context of the Mount Sinabung eruption refugee settlement area in Siosar Kapab Regency, Karo Regency. The increase in surface runoff and sedimentation discharge has a direct impact on the water quality, which can be caused by domestic waste and other human activities.

Conclusion

Overall, this research highlights the importance of understanding the impact of land conversion on ecosystems. There needs to be appropriate conservation policies and steps to minimize the negative impacts caused by land conversion, so that the environment can remain balanced and water quality is maintained. Good conservation and management efforts are needed to maintain the quality of land and water, so that it will support the sustainability of ecosystems in the Siosar area, Karo Regency.

Recommendations

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

  1. Conservation policies: The government should implement conservation policies to minimize the negative impacts caused by land conversion.
  2. Community involvement: The community should be involved in the conservation efforts to maintain the quality of land and water.
  3. Education and awareness: Education and awareness programs should be implemented to raise awareness about the importance of conservation and the impact of land conversion on ecosystems.
  4. Monitoring and evaluation: Regular monitoring and evaluation should be conducted to assess the effectiveness of conservation efforts and to identify areas for improvement.

Limitations

This study has several limitations, including:

  1. Limited scope: The study only focuses on the Mount Sinabung eruption refugee settlement area in Siosar Kapab Regency, Karo Regency.
  2. Limited data: The study relies on secondary data, which may not be comprehensive or up-to-date.
  3. Limited analysis: The study only analyzes the impact of land conversion on surface runoff and sedimentation, and does not consider other environmental factors.

Future Research Directions

Future research should focus on:

  1. Long-term monitoring: Long-term monitoring should be conducted to assess the impact of land conversion on ecosystems over time.
  2. Multi-disciplinary approach: A multi-disciplinary approach should be used to consider the impact of land conversion on various environmental factors, including water quality, soil quality, and biodiversity.
  3. Community-based conservation: Community-based conservation efforts should be implemented to involve the community in conservation efforts and to raise awareness about the importance of conservation.

Conclusion

In conclusion, this study highlights the importance of understanding the impact of land conversion on ecosystems. The conversion of land from forests to settlements has a significant impact on the environment, particularly in the context of the Mount Sinabung eruption refugee settlement area in Siosar Kapab Regency, Karo Regency. The increase in surface runoff and sedimentation discharge has a direct impact on the water quality, which can be caused by domestic waste and other human activities. Good conservation and management efforts are needed to maintain the quality of land and water, so that it will support the sustainability of ecosystems in the Siosar area, Karo Regency.
