H Historic public spaces play an important role as venues for social interaction, cultural activities, and recreation, while also representing a city’s identity and historical values. taman fatahillah, located in the kota tua (old town) area of jakarta, is one of the heritage public spaces with a high intensity of activities, including the presence of street vendors (pedagang kaki lima/pkl) as part of the informal economic sector. the presence of street vendors in heritage public spaces often generates debate, as on the one hand it can enhance spatial vitality and visitor convenience, while on the other hand it may affect comfort levels and the visual quality of the area.this study aims to analyze visitors’ perceptions of the presence and activities of street vendors and their relationship to the level of public space comfort at taman fatahillah as a historic public space. the research adopts a quantitative approach using a survey method. data were collected through likert-scale questionnaires distributed to 150 visitors to taman fatahillah. the research variables consist of visitors’ perceptions of street vendor activities as the independent variable (x) and public space comfort as the dependent variable (y), which includes aspects of physical, visual, and social comfort, as well as the overall visiting experience.data analysis was conducted using descriptive and correlational methods, employing the pearson product moment correlation. the results indicate that visitors’ perceptions of street vendor activities generally fall within the neutral to moderately comfortable category, suggesting both acceptance and caution regarding the impacts of street vendor activities. the correlation analysis reveals a positive relationship with a moderate level of strength between visitors’ perceptions of street vendor activities and the level of public space comfort. these findings suggest that the presence and activities of street vendors, as perceived by visitors, do not dominantly reduce the comfort of heritage public spaces; rather, their contribution to comfort is conditional and influenced by aspects of spatial arrangement, density, and visual orderliness.the results of this study emphasize the importance of managing and organizing street vendor activities in an integrated manner with the spatial and visual characteristics of heritage public spaces, in order to maintain a balance between the preservation of historical values, informal economic activities, and visitor comfort.
