Abstract
The urban challenge in realizing a green city for the purpose of a sustainable city is air pollution resulting from vehicle emissions (Carbon monoxide/ CO2). Reducing vehicle emissions can be done by providing green open spaces. In Kendari City, a potential area for the development of green open space is the Bahteramas General Hospital. Activities in the area and around the Bahteramas General Hospital in Kendari City are quite high so that they contribute to emissions (CO2). The object of research analysis is the number of vehicles (daily traffic), the capacity of electricity use, the area of the Bahteramas General Hospital and the area of the existing green open space. The results showed that the type of vehicle that contributes high to CO2 is a motorcycle. The use of fuel as a source of emission (CO2) which contributes to premium types of greenhouse gases, diesel and the use of electrical energy. The absorption capacity of the existing green open space has not been able to reduce CO2 emissions, so it is necessary to expand the green open space to control greenhouse gases.
Highlights
Sustainable development is defined as development activities that are carried out continuously and provide continuous benefits for the survival of future generations. the concept of a green city as an effort to realize sustainable city development by presenting various development alternatives that are more equitable and humanistic (Mamie et al, 2021)
The concept of sustainable development is packaged in the millennium development goals (MDGs) which are further refined by the concept of sustainable development goals (SDGs)
Calculation of the magnitude of mobile emission sources originating from motorized vehicle activities by calculating the average volume of vehicles in the average daily traffic volume and fuel consumption per vehicle type based on the distance traveled in the study area
Summary
Sustainable development is defined as development activities (especially urban areas) that are carried out continuously and provide continuous benefits for the survival of future generations. the concept of a green city as an effort to realize sustainable city development by presenting various development alternatives that are more equitable and humanistic (Mamie et al, 2021). The transportation sector is the most contributing to air pollution which in turn has a negative effect on humans as a result of vehicle emissions that produce harmful substances (NOx, SO, CO2, VHC, and particulates) (Andriono, 2013) This is commonly found in cities in the world, especially developing countries such as Indonesia. If the wide discrepancy between green open space and motor vehicle exhaust emissions continues to occur, in the future with the rate of population growth and increasing vehicle ownership, it is feared that it will be difficult to achieve the “city in a park” and the goal of sustainable urban development through the green city concept is difficult to realize. Hospital visitors and the surrounding community need adequate oxygen intake for environmental comfort and health
