Malang is the second largest city in East Java after Surabaya. In general, the problems in Malang are similar to those in other big cities in Indonesia. Although urbanization is especially important for economic growth, it results in the degradation of environmental quality and promotes flooding, congestion, urban infrastructure problems, and slums. The tendency of the built-up area of Malang to increase faster, along with the population growth and development expansion, indicates that the city will surpass the region's holding capacity sooner than it should. Such conditions create an uncomfortable living environment. One way to make the city more comfortable, safe and in harmony with nature is to apply the green city (GC) concept. The purpose of this study is to analyse and evaluate the implementation of the GC concept in Malang. This research employs the gap analysis method, which compares the ideal GC conditions with the actual conditions in Malang. The results indicate that of the eight GC indicators, Malang focuses on three: green planning and design, green open space, and green community. Building construction comprises the lowest score of 0%, while the highest score is green open space indicator with 50%.

Abstract:In the process of building and maintaining houses, residents as individuals and social human beings depend on their respective interests for improving their dwellings. The strength of tradition supports the element of stability from one generation to another. It indicates that there are groups of people whose traditions will generally be passed on to the next generation. Tradition is still maintained when utilizing the home as a Home-based Enterprise (HBE). HBE developments are based on a family's economic growth rate and also consider their household needs. In homogeneous houses, it appears that there is vernacular activity in building or repairing homes. As an example, in the case of HBEs, housing activities are maintained during the process of urban growth. Houses need to be expanded according to the needs of households and business activities within a limited urban area. In this research the pattern of house development based on vernacular HBEs, encompassing both living activities and business activities, has been investigated.

Abstract:Environmentally, sustainable development will increase durability to any changes in the environment. Planning and urban design as a form of physical intervention in urban development should anticipate phenomenon of global warming through design decisions. A balanced development between the physical environment of development and environmental conservation should be done to achieve a healthy urban environment for present and future generations. The balance between green space and developed space with an integrated system of environmental infrastructure will increase the carrying capacity of an urban environment. Green city planning and design is one solution to global warming phenomenon. Green city concept was conceived as an answer that emphasizes aspects of environmental sustainability considerations in solving the urban problems (Murota and Ito, 1996). Green city planning implications in urban planning and design approach is the realization of the overall ecological city (Eco-city). This paper aims to discuss the concept of city planning and design approach that is able to eliminate global warming. Purpose of the discussion in this article was to determine whether the product of city planning has to anticipate problems of global warming became a major issue of urban development. The discussion in this article is the result of a review of the design of Long-Term Development Plan
