This research aims to analyze environmental conditions in Jakarta and identify practical solutions to air pollution, water pollution, and waste management. The research methods include air and water quality monitoring with modern sensors, analysis of emissions data, and interviews with stakeholders. Simulation models evaluate the impact of various interventions, such as public transportation improvements and pollution control technologies. The research results show that Jakarta faces significant challenges, with pollutant concentrations often exceeding safe limits. Simulation models estimate that reducing vehicle emissions and using renewable energy could reduce air pollution by up to 30% within five years. Pilot projects such as sensor-based air quality monitoring systems and household waste separation programs are progressing positively. However, budget constraints and resistance to change are still obstacles. The conclusions of this research emphasize the importance of integrating modern technology, strengthening environmental policies, and active community involvement. This research also offers a model that can be implemented by other cities in developing countries. Suggestions include policy adjustments, increased financial support, and community education programs to increase awareness and participation in environmental improvement.
