Abstract

Background: The Provincial Government of DKI Jakarta issued Governor Regulation No. 155 of 2018 and its amendments regarding Traffic Restrictions with the Odd-Even System. This regulation aims to reduce congestion levels on 16 main roads. By decreasing congestion, the expected outcome is a reduction in air pollution levels in DKI Jakarta. However, there is concern that the implementation of Governor Regulation No. 155 of 2018 might lead to an increase in conventional car purchases, as affluent individuals may buy two cars with odd and even license plates. This choice is driven by the continued use of fossil fuel-based energy. This study aims to evaluate the effectiveness of Governor Regulation No. 155 of 2018 in reducing traffic congestion and air pollution in DKI Jakarta. Additionally, the study seeks to understand the relationship between the implementation of the odd-even traffic restriction system and electric vehicle sales. Methods: The research was conducted by analyzing secondary data obtained from government agencies and other institutions. Furthermore, a questionnaire survey was administered to individuals active on the 16 main roads where the odd-even policy is enforced. The study also analyzed the purchase levels of electric cars, which is one method for Jakarta residents to avoid fines on odd-even roads. Result: Based on the research findings, Governor Regulation No. 155 of 2018 and its amendments have not yet effectively reduced traffic congestion and air pollution in DKI Jakarta. Conclusion: The increase in electric car purchases potentially introduces new issues, such as the unsustainable management of nickel mines required for electric vehicle battery production. Therefore, other sustainable strategies are needed to address traffic congestion and air pollution. Novelty/Originality of the study: This study shows that Governor Regulation No. 155 of 2018 has yet to reduce congestion and air pollution in DKI Jakarta effectively. In addition, the increase in the purchase of electric cars as a solution to avoid fines has raised new problems related to the environmental impact of electric vehicle battery production.

Abstract

The Indonesian government is firmly committed to achieving Net Zero Emission (NZE) by 2060. This involves transitioning the electricity sector by progressively replacing fossil fuels with renewable energy sources. The goal is to have a renewable energy mix of at least 23% by 2025 and at least 31% by 2050. This commitment applies to all provinces in Indonesia, including DKI Jakarta Province. This study aims to analyze the willingness and ability to pay DKI Jakarta Province residents for potential changes in energy prices resulting from an energy transition that increases the renewable energy mix. By 2023, the renewable energy mix in Indonesia reaches 13.3%. Coal is still the most widely used energy sources ini Indonesia, reaching 39,7%. This research employs quantitative methodology to ascertain the purchasing ability of the community for electrical energy through questionnaire distribution to PT PLN (Persero) customers. The respondents of this research are PT PLN (Persero) customers with household categories at all levels, which are R1, R2 and R3. The result showed that that a vast majority of respondents (97%) recognize coal as the primary energy source for electricity generation, with 96.3% acknowledging its negative environmental and health effects. Awareness of the government's energy transition policy is high at 97.6%, and 93.3% of respondents support the shift to renewable energy. However, the willingness to pay higher electricity tariffs declines across customer categories, with R1 at 54.13%, R2 at 47.83%, and R3 at 33.33%. The research results on respondents' ability to pay show that R1 category respondents represent 5% of the initial bill.  The R2 and R3 categories represent a maximum of 10% of the initial bill.
