Land use planning aim at improved sustainable use and management of resources. This would imply that those who use and manage the resources are the key players in the planning process. Thus planning for sustainable land management can only be relevant and successful when all stakeholders are involved. In this study considers on biophysical characteristics to make land evaluation, with special attention to open space. The objectives of this study were: (1) to analysis the existing land use based on land suitability for open space with attention to paddy field, dry land cultivation, and protected area; and (2) to calculate the area of open space that are paddy field, dry land cultivation, and protected area based land suitability and compare to the existing condition. The result of this study is expected to be used as an input for decision maker in the term land use management decision making at study area. The capabilities of Geographic Information Systems (GIS) were used to determine suitable area for specific land use in study area. The research has been applied in Depok Municipality, West Java Province. The result indicates that in study the total area of existing open space is 42.94% or about 8,600.45 Ha from the total area of study. The existing paddy field cultivation based on land suitability evaluation, i.e. 69.53% on area with suitability class S1 (Highly Suitable); 25.11% on S2 (Moderately Suitable); 5.33% on S3 (Marginally Suitable); and 0.02% on N class (Not Suitable). For dry land cultivation the existing condition 63.36% on area with suitability class S1 (Highly Suitable); 28.82% on S2 (Moderately Suitable); 7.60% on S3 (Marginally Suitable); and 0.22% on N class (Not Suitable). While the protected area that is used for any development activity in existing (infringe area) is 2.39% from the total area of study or about 479.17 Ha.

Distribution grids the number of distributed generation units is increasing rapidly. Combined heat and power (CHP) plants and wind turbines are most often installed. Integration of these DG units into the distribution grid leads to planning as well as operational challenges. In this paper proposed a new algorithm for Distributed Generator (DG) placement and sizing for distribution systems based on a novel index. This paper proposes a new algorithm for Distributed Generator (DG) placement and sizing for distribution systems based on a novel index. The index is developed considering stable node voltages referred as power stability index (PSI). A new analytical approach is adopted to visualize the impact of DG on system losses, voltage profile and voltage stability. The proposed algorithm is tested on 12-bus, modified 12- bus and 69-bus radial distribution networks. The test results are also compared and found to be in close agreement with the existing Golden Section Search (GSS) algorithm.

The multi-objective optimization of carbon fibre reinforced plastics (CFRP) circular hollow sections using genetic algorithm for engineering structures is discussed. A MATLAB program incorporating Genetic Algorithm was used to obtain an optimal section. The result show that the optimal mass of CFRP required is 320kg while the thickness, inner radius and external radius were obtained as 44.2mm, 165mm and 127mm respectively to adequately sustain a load of 1000kN without failure, which represent loads from offshore structures, bridges, high raise buildings etc.
