Study of Inventory of Greenhouse Gas Emissions (CO2 and CH4) from Household Waste in Medan Area District, Medan Polonia District, and Medan Tembung District

The Alarming Reality of Greenhouse Gas Emissions from Household Waste in Indonesia

The solid waste sector in Indonesia is a significant contributor to greenhouse gas emissions (GHG), particularly carbon dioxide (CO2) and methane (CH4). In an effort to combat climate change, the government has set a target to reduce GHG emissions to 0.048 Gigaton CO2e in 2020 for this sector. This commitment is outlined in PP No. 61 of 2011 concerning the National Action Plan for Decreasing GHG Emissions and PP No. 71 of 2011 concerning the Implementation of National GHG Emission Inventory. As a result, every local government, including regencies and cities, is required to conduct an inventory of greenhouse gas emissions.

The Study's Focus: Medan Area District, Medan Polonia District, and Medan Tembung District

This study focused on the sub-districts of Medan Area, Medan Polonia, and Medan Tembung to calculate and select a scenario for decreasing greenhouse gas emissions from household waste. The three scenarios studied are:

Scenario 1: Processing at the Source (Through Composting Techniques): This scenario involves processing waste at the source through composting techniques, which can reduce the amount of waste that needs to be transported and managed.
Scenario 2: The Existence of a Garbage Bank: This scenario involves the establishment of a garbage bank, where waste is collected and processed, and the resulting products are sold or used as raw materials.
Scenario 3: Establishment of Integrated Waste Processing Places (TPST): This scenario involves the establishment of integrated waste processing places, where waste is processed and managed in a centralized facility.

Methodology and Results

The calculation of GHG emissions uses the Tier 2 method, which has been determined by the Intergovernmental Panel on Climate Change (IPCC). The results obtained showed that GHG emissions from household waste in Medan Area District were 1,777.07 tons of CO2E, Medan Polonia District at 1,050.02 tons of CO2E, and Medan Tembung District at 3,195.73 tons CO2E.

Analysis and Conclusion

From the analysis conducted, the processing scenario at the source (Scenario 1) was chosen as the focus point of the decrease in greenhouse gas emissions that was most effective for these three districts. Composting at the source is proven to provide the highest score in measurement of the effectiveness of each scenario. This method not only reduces the amount of waste that must be transported and managed but also improves the quality of the soil through the use of the resulting compost.

The Importance of Handling Waste at the Source

Managing waste in Sumber is a crucial step in dealing with environmental crises. By implementing processing in sources, we can encourage community participation in reducing waste and alternative use of organic materials efficiently. It also educates the public about the importance of good waste management, so that environmental awareness can increase.

Long-term Impact on the Environment

If the source of resource-based waste treatment can be applied consistently, it will not only help reduce greenhouse gas emissions, but also has a positive impact on public health and environmental quality. In addition, the successful implementation of this scenario can be a model adapted by other regions, advancing efforts to reduce emissions as a whole, and contribute to national targets in overcoming climate change.

Conclusion

From this study, it appears that the handling of effective household waste in Medan Area District, Medan Polonia, and Medan Tembung can significantly cut greenhouse gas emissions. By prioritizing processing scenarios in the source, the local government together with the community can collaborate to create a cleaner and sustainable environment. Through good policies and practices, this effort can be a concrete step in reducing negative impacts on climate and the environment.

Recommendations

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

Implement processing at the source: The local government should prioritize processing at the source through composting techniques to reduce greenhouse gas emissions.
Establish garbage banks: The establishment of garbage banks can provide an alternative use of organic materials and reduce the amount of waste that needs to be transported and managed.
Establish integrated waste processing places (TPST): The establishment of integrated waste processing places can provide a centralized facility for waste processing and management.
Educate the public: The public should be educated about the importance of good waste management and the benefits of processing at the source.
Monitor and evaluate: The local government should monitor and evaluate the effectiveness of the implemented scenarios and make adjustments as necessary.

By implementing these recommendations, the local government can reduce greenhouse gas emissions from household waste and create a cleaner and sustainable environment for the community.
