Ruang esensinya adalah tempat manusia hidup dan beraktivitas. Namun tidak semua aktivitas dapat terakomodir karena setiap ruang dibatasi dengan fungsinya masing-masing. Bagi ruang pribadi keterbatasan ruang tersebut merupakan karakteristik utama bagi ruang itu sendiri sedangkan pada ruang publik yang memiliki berbagai macam aktivitas harus dapat menampung berbagai aktivitas di dalamnya. Untuk itulah perlu dilakukan kajian mengenai ruang publik terhadap permasalahan keterbatasan ruang yang sering ditemui. Tulisan ini menggunakan metode kualitatif dengan melakukan pendekatan kajian literatur. Ada beberapa literatur yang diambil dari beberapa ahli serta beberapa hasil penelitian dalam artikel jurnal untuk mendukung teori dan melihat kenyataan di lapangan. Pada akhir tulisan diambil suatu kesimpulan bahwa keterbatasan ruang publik terhadap berbagai macam aktivitas yang berlangsung di dalamnya dengan terbentuknya ruang bersama baik secara permanen maupun bergantian (waktu tertentu).Kata-kata Kunci: arsitektur, ruang publik, aktivitas, ruang bersamaURBAN PUBLIC SPACE STUDIES BETWEEN ACTIVITIES AND LIMITATIONSThe essence of space is a place where humans live and doing their activities. But not all activities can be accommodated because space is limited by their functions. For private space, space limitations are the main characteristics for space itself, while in public spaces that have various kinds of activities must be able to accommodate multiple activities in it. For this reason, a study of public space needs to be done on the problems of space limitations that are often encountered. This paper uses qualitative methods by conducting a literature review approach. There is some literature taken from several experts and several research results in the journal for support the theory and see the reality in the field. At the end of the writing, it was concluded that the limitations of the public space for various kinds of activities take place in it with the formation of shared spaces both permanently and alternately (certain times).Keywords: architecture, public space, activity, share spaceREFERENCESAgustapraja, H.
