Potential of important vegetation in Vatulemo Green Open Space

Abstract

Green Open Space is a space that is fully arranged with various plants. The expansion of green open space in Palu City is designed to meet the minimum minimum area of greeneries at 30% of the city area. Landscape areas with different types of vegetation have different abilities to provide thermal comfort. This research aims to analyze the vegetation structure and the ability of vegetation to reduce air temperature in Vatulemo's green open space. This research method are analysis of the vegetation structure in Vatulemo City Park's green open space based on the types of vegetation components that comprise the green open space and exploratory analysis of the ability of vegetation with the highest importance value (IVI) to reduce air temperatures that provide thermal comfort for various living things. The results showed a codominance between the vegetation was found, for instance, Cuphea sp, Samanea saman, Cynodon dactylon, Terminalia mantaly and Tabernaemontana divaricata. The average temperature under and outside the canopy of the vegetation was quite different. The temperature under the canopy is lower than outside the canopy. The difference in surface temperature under and outside the canopy is influenced by the primary factor of shading arising from the thickness of each vegetation's canopy. As a result, according to SNI 03-6572-2001, temperature under canopy vegetation with the highest importance are classified as comfortable warm standard temperature. In Vatulemo Park, planting canopy trees remains extremely scarce. Each vegetation has a different ability to create thermal comfort.
