Abstract. Javan Hawk-Eagle (Nisaetus bartelsi; JHE) is a law-protected endemic raptor which currently faced the decreased in number and size of habitat patches that will lead to patch isolation and species extinction. This study assessed the degree of connectivity between remnant habitat patches in central part of Java by utilizing Conefor Sensinode software as an additional tool for ArcGIS. The connectivity index was determined by three fractions which are infra, flux and connector. Using connectivity indices successfully identified 4 patches as core habitat, 9 patches as stepping-stone habitat and 6 patches as isolated habitat were derived from those connectivity indices. Those patches then being validated with land cover map derived from Landsat 8 of August 2014. 36% of core habitat covered by natural forest, meanwhile stepping stone habitat has 55% natural forest and isolated habitat covered by 59% natural forest. Isolated patches were caused by zero connectivity (PCcon = 0) and the patch size which too small to support viable JHE population. Yet, the condition of natural forest and the surrounding matrix landscape in isolated patches actually support the habitat need. Thus, it is very important to conduct the right conservation management system based on the condition of each patches.

The park is an green open space thar is managed and used by the community for various outdoor aktivities. Parks are usually arrange to have the value of beauty and comfort for garden users. Beautiful, attractive and harmonious garden landscapes are needed to achieve comfort for the visual connoisseurs of park users. Structuring the park as a green open space that can be used by park users to frequently visit the park. The purpose of evaluation research is to analyze green space as aesthetics. The method used in this study conducted a survey and scoring conducted by calculating the percentage of effectiveness, by calculating the percentage of achievement criteria. The results achieved by the green open space Kencana Park have the value of the effectiveness of the green space function for aesthetics of moderate value, with a value of 63.98%. This is because the functions of green open space cannot be maximized.
