Urban landscapes have the potential to provide a variety of benefits for urban communities. Urban landscapes can be a public space that can accommodate various kinds of public activities but also can be an ecological space that can provide space or means of protection for the sustainability of natural and environmental resources. The urban area of Palu city in its landscape arrangement tends to not pay attention to climate aspects as one of the factors that influence environmental sustainability and in creating productive public spaces. The main objective of this study is to develop a landscape plan for the urban area of Palu city based on mitigating land surface temperature. The specific objectives of the study include analyzing and determining the surface temperature distribution of urban areas in Palu City, analyzing the vegetation density index of the urban area of Palu City, formulating concepts and developing urban landscape landscape plans based on land surface temperature distribution and index of vegetation density. The approach used in this study uses a landscape planning approach which consists of several stages starting from inventory or data collection, data analysis, synthesis and planning. Based on spatial data on land surface temperature distribution and vegetation density index results obtained showed the highest distribution of temperature distribution in almost all areas of the East Palu Sub District and parts of West Palu Sub District and the lowest temperature distribution was in parts of West Palu Sub District. Based on the results of the spatial analysis of land surface temperature distribution and vegetation density index, the results show that landscape development plans with intensive green arrangement intensity are located in the East Palu Sub District and part of West Palu Sub District and landscape development plans with the intensity of non-intensive green is located on Most of the West Palu Sub District Area.

The provision of daylighting within a building performs an essential function, not only for health and visual comfort but also for energy efficiency in lighting. In tropical areas, however, excessive sunlight radiation and intensity have become a common problem in providing a sufficient amount of daylight, because they can lead to overheating. Several daylighting strategies are often employed by vernacular houses to provide daylight and to avoid heat radiation and glare. These strategies often use ray-ban glass windows material, as well as external and internal shading devices. This paper aims to investigate daylighting strategies in tropical coastal vernacular buildings and their potential application for improving daylighting performance in modern houses in the same climate. The daylight performance of three houses in a tropical coastal area was investigated via field study. The samples were chosen purposively based on construction, building material, building height and window material. Outdoor and indoor light illuminance were measured simultaneously. Indoor measurement points were placed at a height of 0.7 meter above the floor level, with 1-meter space grids. The daylight factor and illuminance level were used as performance indicators. The results indicate that the sampled houses perform poorly in regard to daylighting. This condition was caused by factors such as small-sized windows, the use of Ray-ban glass combined with the use of curtains that blocked almost 30% of daylight. Better daylighting conditions were observed in rooms with large openings (20%-40%).

ABSTRACT Analysis of the Availability and Requirements of Green Open Space on Service Centre Area of The City (Case Study on Palu Timur District, Palu City) The development on urban growth at this time indicates unbalance movement activities, where many of it should have be able to maintain and ensure its sustainability of resources and preservation of environmental quality. One effort to minimize the negative impact of the environmental hazards against physical development in urban area is through green open space planning. The purpose of this study was to identify and analyze the needs and availability of green open space in the service center area of Palu city based on area, population and need for oxygen. The results showed that the availabilty of existing green open space in the service centre area of Palu city was 39,49 hectare and the result of green open space requirement in Palu service centre area based on area, population and need for oxygen were 180 hectare, 78,81 hectare and 43,89 hectare respectively. Keywords : green open space, availability, needs

The Use of Landsat Image For Land Cover Classification On Urban Landscape Of Palu CityOne of effort that can be done for knowing urban development is with seeing land cover information. By land cover map can be kown the information of kind of land cover, area of each land cover and thedistribution of the use of space on the region. Satellite image is one of media that can be used for obtaining the information of land cover. This research purpose was for analysing the use of landsat image for determining the land cover classification on urban landscape using geographic information system. Classification proces of satellite image was started by merging band and cropping image, geometric correction and classification using image classification and the data from classification was converted from raster data to the vector data. From conversion result was obtained information of land cover class for every kind of land cover. Results of land cover class consist of building with area 3110, 79 ha, forest with area 1689,34 ha, farm with area 386,67 ha, and water body 830,35 ha.
