The existence of public open space is essential for a city, not only to beautify the visual area but also as a space for community interaction, a place for play, recreation, and greening the city. Tirto Agung Park is one of the public open spaces built by the Semarang City Government, which serves the urban community, mainly people of Tembalang and Banyumanik Districts. The park surrounding area is livelier, so the government claims this park is a thriving public space. However, the park leads to the emergence of cafes, shophouses, apartments, and street vendors, making some areas crowded. Most park visitors are people from outside, which raises the question of how attached the people who live around are to the park’s existence. Therefore, this research aims to identify the green-placemaking of Tirto Agung Park by determining the park’s ability to accommodate the community. Placemaking is an effort to strengthen the relationship between public space and visitors determined from several variables, such as access and linkages, sociability, uses and activities, comfort, and image. The research method used is quantitative, and data collection methods through field observation and questionnaires. The analytical methods are descriptive quantitative and spatial analysis methods to determine the activity and space use around the park, the relationship between public open spaces and the community (behavioral mapping), and mapping the components of placemaking. The results showed that placemaking has occurred in Tirto Agung Park, but some aspects still need improvement to enhance the placemaking further.
