Gang sebagai Tempat Aktivitas di Permukiman Perkotaan Referensi Kampung di Kota Surabaya

Kampung merupakan permukiman perkotaan dengan keterbatasan tempat aktivitas bagi penghuni. Kampung memiliki keunikan yang khas dalam pembentukan tempat aktivitas.Hal ini karena penghuni tidak hanya beraktivitas di dalam rumah namun juga di luar rumah, khususnya di gang. Paper ini menerangkan secara naturalistik kualitatif tentang bagaimana penghuni kampung membentuk place di gang kampung untuk beragam aktivitas individu dan bersama. Hasil penelitian menunjukkan bahwa gang kampung berfungsi dengan baik sebagai link (jalur sirkulasi) dan tempat aktivitas yang adaptable, fleksibel, dan negotiable. Pembentukan tempat aktivitas di gang kampung dipengaruhi oleh karakteristik space kampung, aktivitas, aktor dan makna gang bagi penghuni kampung.Kampung is a spontaneous urban settlement that lack of an inhabitant’s place activity. Kampung has unique ways for forming an activity place due to where it placed. Kampung’s inhabitant not only do their daily activities inside their houses but also in the kampung’s alley. The objective of research is understand how the inhabitant of kampung are making a place activity at alley. The research method is qualitative approach with naturalistic paradigm. The result showed that the kampung alley are running well as a link (channel of movement) and an activity place that adaptable, flexible, and negotiable. The kampung alley as an activity place formed by space characteristic of kampung, inhabitant’s activities at alley, actor and the meaning of alley for inhabitant.

Spatial Dissipative Structures in Excitable Media (Plankton, Soil Bacteria. . . .)

A general, the simplest model of a spatial dissipative structure arising in an excitable medium is constructed, containing at least two components interacting with each other with their own mobility. One of these components (active) uses the other component as food. It is shown that such a model leads to a stationary stable spatial distribution of the components in the form of Liesegang bands. As specific examples of the formation of spatial dissipative structures, structures arising in plankton consisting of phytoplankton and zooplankton and in the soil containing the bacterial population and the nutrient substrate are considered. Bifurcation diagrams are constructed in the parameter space, characteristic for each of the considered excitable media, which determine the conditions for the formation of dissipative structures in these media. The existence in the plankton of a strange attractor of a previously unknown shape in four-dimensional phase space has been discovered.

Vertical Extension and Improving of Existing Buildings

Low-density urban models, widely diffused in Spain until 2008, have been strongly criticized because they produce a great strain on the land, high infrastructure costs, increasing maintenance expenses, energy waste and pollution from excessive transport, time wasted commuting and more bedroom communities. To counterbalance this effect, opponents are claiming for a review of the capacity that the conventional city, with its higher population density and mixed uses, may still possess. One possibility that has been explored is the vertical extension of buildings, which capitalizes on the remaining buildable space characteristic of many older buildings, and at the same time, refurbishes the housing block and improves standards of energy efficiency, safety and accessibility. The challenge is not only technical - it is clear what needs to be done and how to do it - but it is also social and fiscal; in other words, how do we get organized and how do we finance such a project? The preferred construction system for vertical extensions is industrialized and uses two main materials: steel and wood. The system involves the use of two-dimensional panels and 3D pods that, once completed in the factory, are transported to the worksite, lifted by a crane and installed on the roof of the building. From refurbishing the existing building to adding the new vertical extension, the entire operation takes four months. The experience of this vision and its application in the area of the Example in Barcelona, coming soon to other central neighborhoods in Spanish cities, allows us to present our first results: the detection of over 2,000 buildings with remaining buildable space, the need to vertically extend 50 buildings and our completed projects, in some cases already inhabited, of which half a dozen are currently undergoing environmental evaluation using our own tool.
