Pada awal 2000-an, banyak ekspatriat Jepang menghuni daerah Blok M sehingga terjadilah kompleks Little Tokyo yang terdiri dari bangunan-bangunan komersial low-rise seperti restoran-restoran Jepang, kafe dan bar. Tetapi, pada saat ini, tidak ada ruang publik dalam kompleks Little Tokyo yang dapat memfasilitasi kegiatankegiatan sosial sehingga komunitas Jepang tidak dapat berkembang. Berkelanjutan sosial adalah hubungan antara masyarakat dan built environment (Woodcraft et al., 2012). Hubungan ini dapat ditingkatkan melalui penyediaan ruang publik yang dapat memfasilitasi kehidupan sosial dan memperkembangkan sense of community. Dengan demikian, tujuan dari penelitian ini adalah mengusulkan desain ruang publik yang dapat menjadi pusat interaksi sosial yang merupakan faktor penting dalam menyelesaikan masalah sosial kawasan Little Tokyo. Penelitian ini dilakukan dengan cara studi literatur untuk memahami teori-teori berkelanjutan sosial, ruang publik dan hubungannya, studi preseden untuk membandingkan kesimpulan studi literatur dengan strategi-strategi yang telah diterapkan, observasi tapak untuk mengumpulkan data-data seperti infrastruktur yang eksisting dan kualitas spasial kawasan Little Tokyo, dan survey dilakukan untuk mendapatkan pemahaman budaya dan kultur komunitas Little Tokyo. Hasil penelitian ini merupakan perancangan baru untuk kawasan Little Tokyo yang memenuhi kriteria spasial ruang publik, yaitu community center dan upgraded pedestrian walkways. Community center yang dirancang memiliki program yang mendukung aktifitas komunitas Jepang seperti workshop, martial arts gym dan amphitheatre. Selain itu, upgraded pedestrian walkways merupakan perancangan jalan pejalan kaki yang lebih memadai dengan adanya zona jalan dan elemenelemen desain seperti street furntiture. Upgraded pedestrian walkways tersebut dirancang untuk meningkatkan walkability pada kawasan. / In the early 2000s, there were many Japanese expatriates the reside in the Blok M area that resulted a small complex called Little Tokyo that compromises of low-rise commercial buildings such as Japanese restorants, cafes and bars. However, as of now, there are no public spaces in the area that can facilitate social activites and as a result the Japanese community cannot develop. Social sustainability is defined as the relationship between people and the built environment (Woodcraft et al., 2012). This relationship can be developed further with the provision of good public spaces that can facilitate social life and develop a sense of community. Therefore, the purpose of this research is to propose a design of a public space that can be a center for social interactions that is a key factor and role for a solution towards the social problems at hand. This research is done through literature studies to understand the theories regarding to social sustainability, public spaces and its relationship, precedent studies to compare the strategies implemented with the conclusions drawn from the literature studies, site observations to collect the data and information of the existing site, as well as survey that is done collect non-physical information that may be required. The product of this research paper is a proposed design for the Little Tokyo area that implements the criterias of public spaces which compromises of a community center and an upgraded pedestrian walkways. The community center includes the necessary programs that facilitate activities for the community which are workshops, martial arts gym and an amphitheatre. Furthermore, the design of the upgraded pedestrian walkways improves on the quality of street with the use of zonings and design elements such as street furniture. The upgraded pedestrian walkways are designed to help increase the walkability of the streets of the Little Tokyo area.
