The objective of the study is to determine urban forest area, based on carbon dioxyde emission estimation from vehicle traffic and human activities in the city and around. The result of carbon dioxyde emission calculation used as a basic to determine proportional forest area to established. The comprhensive plan of urban forest, covers species and vegetation type that projected to be able to abrsorb the emission. The analysis shows that amount of carbon dioxyde emission from vehicle traffic in the city was 50,186.4 tons/year, meanwhile, carbon dioxyde produced by human respiratory activities was 9,499.47 ton/year. The necessary of urban forest area to absorb the amount of that emission is 12.67 hectare. Calculation of vegetation space approximately 10 x 10 m2, based on assumption that to absorb carbon dioxyde is in the central of city. Therefore to be recommended that the type of the urban forest is recreation forest type, in order to improve aestetic and convenience of the city in the future. The number of species to be planted is consists of 21 species, which 30 % of the forest area will designed as an open space area for community interaction. Therefore, the number of trees to be planted is about 620.56 individu of tree.
This study aims to analyze the role of Green Open Space on Environmental Protection in Ambon City. The method of data collection is done by collecting primary data in the form of micro climate measurements (temperature and air humidity) at each RTH location. Micro climate data is then processed using microscope office excel, to get the results of comparison tabulations and graphs. After the data tabulation value was obtained statistically analyzed by correlation test. this technique aims to determine the effect of green space on air temperature and green space on air humidity in various types of green open spaces. To analyze the effect of Green Open Space on the preservation of the environment of the city of Ambon, a Spearman correlation correlation tool with Pearson control was performed. The results showed that the results of the microclimate measurements carried out on the Green Path each way Dr. Malaiholo, Pattimura road, Piere Tandean road, Dr. Leimena, shows the air temperature and average humidity of Dr. Malaihollo 32.3 ℃ and RH 68.5%, Pattimura road 33.2 ℃ and RH 61.0%, Jalan Piere Tandean 32.5 ℃ and RH 64.0%, Jalan Dr. Leimena 33.0 ℃ and RH 56.7%. Based on the results of the Convenience Analysis, the four green lines are classified as uncomfortable because the average is in the value of> 27.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
