Determining the Right Solution: A Comprehensive Approach to Finding Alternative Locations for Final Processing Places in Deli Serdang Regency Using AHP and GIS Techniques

The problem of waste management has become a pressing issue in urban areas, with far-reaching consequences for the environment. In Deli Serdang Regency, the situation is particularly critical, with only one functioning landfill, Namo Rube Julu TPA, which manages a staggering 638.04 tons of waste per day. The closure of the Raga TPA in 2020 due to maximum capacity has further exacerbated the problem, making it imperative to identify a new disposal location. This study aims to determine the ideal location for a final processing place using the Analytical Hierarchy Process (AHP) method, integrated with a Geographic Information System (GIS), to ensure a sustainable and environmentally friendly solution.

Understanding the Complexity of Waste Management

Waste management is a complex process that requires a comprehensive evaluation of various factors, including government regulations, environmental concerns, and community needs. The selection of a landfill location is a critical decision that can have significant impacts on the environment and the community. Therefore, it is essential to employ a structured approach that can process qualitative and quantitative data, making it easier to make informed decisions.

The Role of AHP and GIS in Waste Management

The AHP method was chosen for this study due to its ability to process complex data in a structured manner, making it easier to prioritize important criteria. This method can help in identifying the most critical factors that must be met in the selection of TPA locations. Meanwhile, GIS is used to visualize spatial data, such as topography, land use, and distance to settlements. The integration of these two methods allows for a more comprehensive and accurate analysis of the alternative location of the TPA.

Important Factors Considered in the Study

This research will consider several important factors, including:

Environmental Factors

Appropriate land availability: The availability of suitable land for the landfill, taking into account factors such as soil quality, water table depth, and proximity to water sources.
Distance to water sources: The distance between the proposed landfill location and nearby water sources, such as rivers, lakes, or coastal areas.
Potential impact pollution on the surrounding environment: The potential risks of pollution to the surrounding environment, including air and water pollution, and the impact on local ecosystems.

Socio-Economic Factors

Distance to residential areas: The distance between the proposed landfill location and nearby residential areas, taking into account factors such as population density and potential social impacts.
Road accessibility: The accessibility of the proposed landfill location via roads, including the availability of transportation infrastructure and the potential for traffic congestion.
Potential social conflict: The potential for social conflict, including issues related to noise pollution, odor, and visual impacts.

Technical Factors

Availability of infrastructure: The availability of necessary infrastructure, including roads, utilities, and communication networks.
Ease of management: The ease of managing the landfill, including factors such as waste collection, transportation, and disposal.
TPA capacity: The capacity of the proposed landfill to handle the volume of waste generated in Deli Serdang Regency.

Benefits and Positive Impacts of the Study

This research is expected to provide significant benefits for Deli Serdang Regency, including:

Finding an Optimal Alternative Location for TPA

Identifying a suitable location: The study aims to identify a suitable location for the final processing place, taking into account environmental, social, and technical factors.
Minimizing negative impacts: The study aims to minimize the negative impacts on the environment and the community, including issues related to pollution, social conflict, and visual impacts.

Increasing Efficiency and Effectiveness of Waste Management

Improving waste management: The study aims to improve waste management in Deli Serdang Regency, including factors such as waste collection, transportation, and disposal.
Reducing waste: The study aims to reduce waste generation and promote waste reduction, reuse, and recycling practices.

Synergy between Parties

The process of determining the location of alternative TPAs requires synergy between parties, including:

Government

Providing data and regulations: The government has an important role in providing data and regulations related to waste management.
Coordinating efforts: The government must coordinate efforts between different stakeholders, including the community, experts, and other government agencies.

Community

Conveying aspirations: The community plays an active role in conveying aspirations and concerns related to waste management.
Participating in decision-making: The community must participate in decision-making processes related to waste management.

Experts

Providing expertise and technical recommendations: Experts provide expertise and technical recommendations related to waste management.
Assisting in decision-making: Experts assist in decision-making processes related to waste management.

With a strong synergy between parties, it is expected to create an appropriate and sustainable solution for waste management in Deli Serdang Regency.
