The study aims to identify challenges and potentials in implementing e-Government, particularly those related to low digital literacy and limited community participation. Using a qualitative approach, the research combines literature analysis from Scopus and Google Scholar databases with bibliometric mapping through CiteSpace software. The findings show that JSS improves transparency, efficiency of public services, and communication between government and citizens, although obstacles remain in terms of socialization and digital readiness. Beyond governance efficiency, JSS also contributes to sustainable urban development by promoting paperless administration, reducing reliance on energy-intensive bureaucratic processes, and enabling more effective urban resource management. These contributions are closely aligned with the Sustainable Development Goals, particularly SDG 11 (Sustainable Cities and Communities), SDG 13 (Climate Action), and SDG 16 (Peace, Justice, and Strong Institutions). Overall, the study highlights JSS not merely as a digital innovation but as a catalyst for resilient, green, and accountable urban governance.
