Roof Garden as an Alternative to Balance Ecological Environment

Abstract

Increasing urban physical development, population growth and various urban activities have reduced green open space and decreased environmental quality resulting in changes to natural ecosystems. Solutions that can be used by implementing a roof garden. This study aims to obtain economic, ecological and aesthetic data. The method used is inductive descriptive analysis method. In this research the priority is farming food crops. Therefore, efforts are needed to expand and improve the function of green open spaces to maintain the sustainability, harmony and balance of urban ecosystems. This roof garden can make the view more beautiful, as a heat insulator, absorbent of pollutant gases, preventing direct solar ultraviolet radiation from entering the house, and reducing noise. Roof gardens can also cool buildings and rooms below so they can save more energy by reducing the use of air conditioning. Roof gardens have ecological benefits, such as absorbing airborne contaminants and retaining rainwater. Roof gardens can increase rainwater intake to be absorbed and stored by up to 30%. In rooftop gardens, wastewater can be used to water plants.
