Public place is a space which has taken a major role in human's daily activity. As a result of social interaction in a setting, people can feel a flicker of emotion for the place which is known as the sense of place. One of the public places taking in the urban scope is plaza. Plaza is a center of social interaction between individuals or groups in the open space. The results of this study produce eight criteria of a plaza with strong a sense of place to make a city more liveable, namely, street, visual image, identity, activity, scale, accessibility, comfort, and sociability. A case study of Glodok in West Jakarta will be analyzed based on those criteria to help Glodok's main concern. Glodok is one of Jakarta's Chinatown trading centers which has a rich history and the cultural value up until now. It used to have a plaza as a place to interact. However, Glodok's population growth is rapidly increased, turning all the open plazas into buildings of shophouses. Although Glodok's history and culture are very well known, Glodok is now very crowded and lacking in some qualities. Therefore, there is a concern that the area's unique culture will slowly disappear; making Glodok lose its sense of place as a Chinatown area.
Kegiatan formal dalam sebuah komunitas tidak terlepas dari kegiatan interaksi sosial. Hal ini dijumpai pula pada kegiatan bergereja di Gereja Kristus Ketapang (GKK), Jakarta. Permasalahan kebutuhan ruang interaksi sosial yang ada adalah tidak tersedianya tempat berkumpul, belajar, bercengkerama, maupun bekerja yang nyaman bagi remaja, pemuda pemudi di tempat ini dan lingkungan sekitarnya yang digunakan sebelum/sesudah kegiatan formal gereja, dan di luar hari Minggu. Sebagai salah satu perwujudan misi GKK yang melaksanakan tanggung jawab sosial, khususnya bagi remaja dan anak-anak muda, maka tujuan dari pelaksanaan pengabdian kepada masyarakat (PKM) ini adalah membantu penyediaan tempat/wadah bagi anak-anak muda untuk berkumpul, bekerja, bersosialisasi, dan melakukan berbagai aktifitas lain, berupa pengembangan ruang interaksi co-working space dan café yang menjadi salah satu “third place” anak-anak muda saat ini. Metode yang digunakan dalam pelaksanaan PkM adalah mengadakan sesi diskusi grup, pengamatan, pengukuran lapangan, dan penyebaran kuesioner. Hasil kegiatan berupa desain co-working space dan café yang diharapkan dapat meningkatkan interaksi sosial, khususnya bagi anak-anak muda baik jemaat maupun lingkungan sekitarnya. Selain untuk memecahkan permasalahan ruang yang terbatas, hasil desain ini diharapkan dapat menjadi contoh pelaksanaan PkM serupa di area lain untuk mencapai kebutuhan ruang interaksi sosial yang nyaman dan sehat, khususnya bagi anak muda.
Beyond confines of the geography, urban form has direct impact to its microclimatic condition. The constituted set of buildings and open spaces contribute to its comfortable wind environment. This paper examines incorporation of open spaces as passive urban ventilation to infiltrate wind into a riverside settlement. The research conducted in warm-humid riverside settlement: Pasar Lama Tangerang. The actual wind environment is below desired breezes for outdoor activity like strolling. Upon actual site conditions, such as prevailing wind and morphology of existing buildings, we established three urban morphology scenarios: (1) ground floor open space, (2) pocket open space, (3) combination scenario. The research coupled with Computational Fluid Dynamics (CFD) simulation to calculate air flow rate and wind flow direction in every scenario. Study results reveal the three scenarios can prevent air flow from stagnating and allow better permeability of urban air. Reducing land coverage (open space) is one of the most efficient strategy to increase air flow rate up to 2 times the existing case. CFD simulation provide comprehensive data and help to understand systems, performance and implication of design. The capacity to measure climatic parameters compared and correlated with morphological and topography characteristic can improve the quality of built environment.
Abstract. Climate change as an ongoing anthropogenic environmental challenge is predominantly caused by an amplification in the amount of greenhouse gases (GHGs), notably carbon dioxide (CO2) in building sector. Global CO2 emissions are emitted from HVAC (Heating, Ventilation, and Air Conditioning) occupation to provide thermal comfort in building. In fact, the amount of energy used for cooling or heating building is implication of building envelope design. Building envelope acts as interface layer of heat transfer between outdoor environment and the interior of a building. It appears as wall, window, roof and external shading device. This paper examines performance of various design strategy on building envelope to limit solar radiation and reduce cooling loads in tropical climate. The design strategies are considering orientation, window to wall ratio, material properties, and external shading device. This research applied simulation method using Autodesk Ecotect to investigate simultaneously between variations of wall and window ratio, shading device composition and the implication to the amount of solar radiation, cooling energy consumption. Comparative analysis on the data will determine logical variation between opening and shading device composition and cooling energy consumption. Optimizing the building envelope design is crucial strategy for reducing CO2 emissions and long-term energy reduction in building sector. Simulation technology as feedback loop will lead to better performative building envelope.
