Increasing urbanization causes urban overpopulation and contributes to various socio-economic problems including congestion, poverty, crime, climate change, and natural disasters. This trend leads to increased demand for energy, water services, and sewage treatment in cities. The smart city concept can be used to achieve improved urban planning management that can face difficult situations in the future. The results of the study show that levels of understanding of smart city standards vary. About 66.67 percent of respondents stated that the city had participated in the assessment and received the title of the smart city.
