KAJIAN POTENSI KOLEKSI POHON LOKAL JAWA DI KEBUN RAYA BOGOR DAN CIBODAS UNTUK FUNGSI ESTETIKA DALAM LANSKAP
Tree plants in the landscape have a very important function for the life of other living things. As an important element in the landscape, the selection of tree species in the landscape needs to be considered. With respect to aesthetic function in the landscape, the selection of tree species may vary based on their physical appearance. The general aim of this research is to study the potential of local tree collection at the Bogor and Cibodas Botanical Garden to fulfill the aesthetic function in the landscape. As for the specific purposes are as follows: (1) assess the ecological distribution of local tree collections of Bogor and Cibodas Botanical Gardens, (2) review the aesthetical performance of local tree collections of Bogor and Cibodas Botanical Gardens, and (3) provide recommendations on the utilization of Java native tree species for aesthetic functions in the landscape.This research was conducted at Cibodas Botanical Gardens and Bogor Botanical Garden. The research procedure is divided into 3 stages: (1) collection and grouping of tree data, (2) processing and analysis of tree data, and (3) assessment of tree aesthetic quality. The results of the processing and assessment of the tree data were used as a reference for the recommended tree species that are potential to be developed. Data of collected tree species were further processed and analyzed based on habitat distribution and morphological characteristics. Furthermore, the Key Performance Index (KPI) assessment technique is used to give value to each criterion. Stages of tree aesthetic quality assessment was done simulated using Scenic Beauty Estimation (SBE) method. Based on the research that has been done, the biodiversity of local tree species found in both botanical gardens is quite high as 223 species can be found in Cibodas Botanical Garden and 469 species can be found in the Bogor Botanical Garden. From this result, there are 52 species that can be found both at Cibodas Botanical Gardens and Bogor Botanical Garden. Then it can be concluded that the distribution of the habitat of local species of Java trees collection of KRB and KRC spread in each region. The highest number is a species of tree scattered throughout Java Island (327 species), from western Java (172 species), from west and central Java (80 species), central Java (21 species), central and eastern Java (13 species), western and eastern Java (11 species), and eastern Java (10 species). In addition, local tree species also have a range of habitat heights ranging from coastal zones (0 masl) to mountain zones (3100 masl). In the tree species studied in KRC and KRB, based on the criteria of aesthetic assessment there were 72 species of trees including into good category, 287 species in medium category, and 23 species in the bad category.
