Land Use Optimization Model in Deli Watersheds (DAS) with Goal Programming and Analytical Hierarchy Process (AHP)

Introduction

The Deli Watershed, a vital ecosystem in Indonesia, has been facing the challenges of unplanned land use due to the increasing population. This has resulted in a negative impact on the ecological and socioeconomic functions of the watershed, leading to an imbalance. To address this issue, a research study was conducted to determine the optimal land use in the Deli Watershed using the Goal Programming and Analytical Hierarchy Process (AHP) approach. This study aimed to develop a land use optimization model that balances various objectives, including environmental sustainability, socioeconomic, and efficient land management.

The Importance of Land Use Optimization

Land use optimization is crucial in maintaining the balance of ecosystems and supporting the lives of the local community in Das Deli. The proper management of land is essential to reduce soil erosion, which is a significant concern for the respondents. According to the study, reducing soil erosion was considered the most important goal, with a score of 0.29. This highlights the great concern people have for erosion problems that can threaten their welfare. The importance of land use optimization cannot be overstated, as it has a direct impact on the livelihoods of the local community and the overall health of the ecosystem.

Implementation of the Optimization Model

This research developed three scenarios to optimize land use in the Deli Watershed. The scenarios, denoted as I, II, and III, showed variations in the addition of forest land area, with increments of 10.9%, 2.16%, and 3.84%, respectively. The results of the study showed that by increasing the forest land area, erosion and runoff were maintained at a fixed number of 48.47 tons/hectare/year and 1.03 liters/hectares/year. These findings demonstrate that by increasing forest land areas, not only can erosion be reduced, but also ecosystem resilience can be increased, which in turn supports the lives of the surrounding community.

Research Methodology

The goal programming method used in this study served to balance various objectives at once, including environmental sustainability, socioeconomic, and efficient land management. The Analytical Hierarchy Process (AHP) was employed to give priority to aspects that were considered important based on responses from respondents. The combination of these two methods allowed for more structured and effective planning. The use of AHP enabled the researchers to identify the most critical factors affecting land use optimization, while the goal programming method ensured that the objectives were balanced and achievable.

The Role of Goal Programming and AHP

Goal programming is a powerful tool for balancing multiple objectives in land use optimization. By using this method, the researchers were able to identify the most critical factors affecting land use optimization and develop a plan that balances various objectives. The AHP, on the other hand, enabled the researchers to give priority to aspects that were considered important by the respondents. The combination of these two methods allowed for a more structured and effective planning approach.

Conclusion

The use of the optimization model in the management of the Deli watershed is crucial to support sustainable conservation and environmental management efforts. By implementing Goal Programming and AHP, this research provides a clear insight into how proper land management can be implemented to reduce soil erosion and create ecological balance in watersheds. Efforts in the future need to be continued to ensure that land management in Das Deli can continue to meet the socio-economic needs of the community while maintaining the quality of the environment.

Recommendations

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

Continuation of Land Use Optimization Efforts: Efforts in the future need to be continued to ensure that land management in Das Deli can continue to meet the socio-economic needs of the community while maintaining the quality of the environment.
Implementation of Goal Programming and AHP: The use of Goal Programming and AHP should be continued in the management of the Deli watershed to support sustainable conservation and environmental management efforts.
Community Involvement: The local community should be involved in the decision-making process to ensure that their needs and concerns are taken into account.
Monitoring and Evaluation: Regular monitoring and evaluation of the land use optimization efforts should be conducted to ensure that the objectives are being met and to identify areas for improvement.

Future Research Directions

Future research should focus on the following areas:

Integration of Multiple Objectives: Future research should aim to integrate multiple objectives, including environmental sustainability, socioeconomic, and efficient land management, to develop a more comprehensive land use optimization model.
Use of Advanced Techniques: Advanced techniques, such as machine learning and geographic information systems (GIS), should be explored to improve the accuracy and effectiveness of land use optimization models.
Community-Based Approaches: Community-based approaches should be developed to ensure that the needs and concerns of the local community are taken into account in land use optimization efforts.
Policy and Regulatory Frameworks: Policy and regulatory frameworks should be developed to support the implementation of land use optimization efforts and to ensure that the objectives are being met.

Limitations of the Study

This study has several limitations, including:

Limited Data: The study was limited by the availability of data, which may not be representative of the entire Deli Watershed.
Simplification of Complex Issues: The study simplified complex issues, such as the impact of land use on ecosystem services, to develop a land use optimization model.
Limited Scope: The study had a limited scope, focusing only on the Deli Watershed, and may not be applicable to other watersheds.
Lack of Stakeholder Engagement: The study did not involve stakeholders, such as local communities and government agencies, in the decision-making process, which may have limited the effectiveness of the land use optimization model.

Conclusion

In conclusion, this study demonstrates the importance of land use optimization in maintaining the balance of ecosystems and supporting the lives of the local community in Das Deli. The use of Goal Programming and AHP provided a clear insight into how proper land management can be implemented to reduce soil erosion and create ecological balance in watersheds. Efforts in the future need to be continued to ensure that land management in Das Deli can continue to meet the socio-economic needs of the community while maintaining the quality of the environment.
