Evaluation of ecosystem services in public green open spaces in Mataram

Abstract

The presence of public Green Open Spaces (GOS) provides numerous benefits to the community and the environment. The objective of this study is to identify and assess the ecological functions of the public green open space ecosystem services in Mataram City using an environmental approach. The research method employed a quantitative descriptive approach, with the research samples being GOS Pagutan, GOS Udayana, GOS Mayura Park, and Selagalas Park. The study was conducted from July to August 2023, using interviews and observations as research instruments. The research conducted in Public GOS in the City of Mataram used spatial analysis and ecosystem services analysis as analytical methods. The study focused on the function of ecosystem services - temperature changes, noise dampening, air and water quality. The findings revealed that there was a significant difference in temperature inside and outside the GOS area. While the noise levels were still above the quality standard of the 4 research samples, only the GOS Pagutan met the specified quality standard. The other areas had relatively high noise levels. There were differences in air quality inside and outside the GOS area. However, the air quality was still below the specified quality standard. The water quality was divided into river water and well water. The coliform value in river water still exceeds the established quality standards, indicating that it is very high and unsafe for consumption, while well water is considered safe as it falls below the established book standards. Regular monitoring and coordination among various parties is necessary to ensure the preservation and maintenance of public GOS.
