STATISTIKA KELOMPOK 6 | ST 21

Summary

Jakarta faces critical waste management challenges, generating over 8,500 tons of waste daily, primarily from households. The issue lies in the uneven distribution of waste collection trucks and limited waste disposal sites (TPS), which leads to environmental problems such as pollution and methane emissions. Data analysis reveals a strong correlation between the number of trucks and waste volume, while the impact of TPS expansion remains statistically insignificant. Solutions include optimizing truck distribution, integrating waste-to-energy technology, enhancing public education on waste segregation, and conducting further environmental impact research. These strategies aim to transform Jakarta's waste management system into a sustainable and efficient model.

Takeaways

• 😀 Jakarta generates 8,527 tons of waste per day, with 63% of it coming from household waste.
• 😀 The main issues in waste management include uneven waste truck distribution, limited Temporary Waste Storage (TPS) facilities, and widespread waste accumulation.
• 😀 The study uses data from government sources such as the Central Statistical Agency and the National Waste Processing Information System to analyze waste management trends in Jakarta.
• 😀 A strong correlation of 0.909 was found between the number of waste trucks and the volume of waste generated, indicating a direct relationship between these two factors.
• 😀 The model suggests that adding one more waste truck increases the waste volume by approximately 5.66 tons per day.
• 😀 There is a moderate positive correlation between the number of TPS facilities and waste generation, but this relationship is not statistically significant.
• 😀 The study highlights the environmental impact of Jakarta’s waste management system, including increased greenhouse gas emissions and groundwater contamination due to waste pileups at TPS.
• 😀 Technological solutions, such as converting diesel trucks to electric and integrating dynamic routing via IoT, are recommended to optimize waste collection.
• 😀 Waste management data analysis from 2020 and 2022 reveals that the waste per truck has increased, indicating inefficiency in waste transport across the city.
• 😀 The findings suggest that conventional methods (more trucks and TPS) have not been effective in reducing environmental burdens, and there is a need for a data-driven, technology-based strategy.
• 😀 Four transformative solutions are proposed: optimizing waste truck distribution, integrating waste-to-energy technology, educating the public on effective waste separation, and conducting further research using Life Cycle Assessment (LCA).

Q & A

What is the main issue with waste management in Jakarta as mentioned in the transcript?

The main issue is the inefficient distribution of garbage trucks and waste collection points (TPS), which leads to waste accumulation, pollution, and negative environmental impacts in Jakarta.

How much waste does DKI Jakarta generate daily?

DKI Jakarta generates 8,527 tons of waste daily, with 63% of this being household waste.

What role do garbage trucks play in the waste management system, according to the analysis?

Garbage trucks are crucial in waste management, as a strong correlation was found between the number of trucks and the volume of waste. More trucks generally lead to more waste being managed efficiently.

What is the correlation between the number of trucks and the volume of waste in Jakarta?

The correlation is very strong, with a coefficient of 0.909, indicating a close positive relationship between the number of trucks and the volume of waste.

What did the statistical analysis reveal about the impact of adding more trucks to the waste management system?

The analysis showed that adding one more truck is expected to increase the waste volume by 5.66 tons per day, and the model's R-squared value of 0.827 indicates that 82.7% of the variation in waste can be explained by the number of trucks.

How does the number of TPS (waste collection points) affect waste volume?

The relationship between the number of TPS and waste volume is positive but weaker, with a correlation coefficient of 0.607. However, it was not statistically significant, meaning that increasing TPS does not have a direct, strong effect on waste volume.

What are some environmental impacts of Jakarta's current waste management system?

The environmental impacts include increased greenhouse gas emissions, groundwater contamination due to waste accumulation in TPS, and threats to marine ecosystems from waste buildup along coastlines.

What solutions were proposed to address waste management inefficiencies in Jakarta?

The proposed solutions include updating the truck fleet, implementing dynamic routing systems using IoT, building modular TPS with advanced technology, converting diesel trucks to electric, and strengthening waste reduction programs at the source.

What is the effect of waste management system inefficiency on the load per truck in Jakarta?

Inefficiency leads to higher waste loads per truck, indicating that there are not enough trucks to manage the waste volume effectively, especially in areas like Jakarta Barat, Selatan, and Timur.

How did the waste management system change from 2020 to 2022?

From 2020 to 2022, while the correlation between the number of trucks and waste volume remained strong, the effectiveness of waste management declined due to truck overloads and the aging fleet. However, TPS capacity increased, with waste volume per TPS rising to 6.16 tons per day in 2022.
