Abstract

Depok is one of Jakarta’s satellite towns with density populations increasing throughout urbanization. The population growth rate of this city has gained by 1,92% in 2021 or an increase of 0,28% since 2020. As an impact of it, the transition of green open spaces (GOS) to built-up land could not be helped. The quantity of vegetation as the main material of GOS that can improve urban quality through evapotranspiration and pollutant reduction keeps dwindling. Therefore, analysis of GOS development priority was needed to prevent the diminish of the city’s ecological value based on Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST) and density population’s intensity in 2021 by using Landsat 8 OLI-TIRS. According to the study, Sukmajaya is one of sub-districts with highest development priority of GOS, especially in business area due to the wide-scale of its GOS is only 3,26 km2 which has NDVI is 0,31 and also its surface temperature is 30,5ºC. Meanwhile, Sawangan and Bojongsari sub-districts are the lowest priority for GOS developments due to having more than 30% of vegetation area and their surface temperature are 28,7ºC and 28,8ºC. The output of this study is a recommendation that used as a reference by the government or any stakeholders to raise awareness of GOS necessary, so the quality of urban ecology could be raised and the health of residents would be achieved.

Abstract

Landscape plant nurseries are propagation and growing areas for trees, shrubs, ground cover plants, vines, water plants and herbs that are associated with several stakeholders such as landscape consultants, maintenance companies, contractors, and ornamental plant sellers. Nurserymen play a crucial role in providing plants for landscape projects, but the limited visibility of some nurseries poses a challenge to the procurement process. To address this issue, it is necessary to conduct a study that maps the location of nurseries and creates a database in several landscape plant production centers to facilitate consumers in meeting their plant needs. The study aimed to inventory plant diversity, analyze procurement and marketing practices in various ornamental plant centers, and assess the impact of different aspects of nurseries on plant application. Conducted from November 2023 to March across 10 districts in Bogor, Cianjur, and Depok regency, the research used descriptive quantitative analysis and correlation analysis to identify relationships between various aspects of plant procurement to identify key aspect for nurseries development. The research findings indicate a considerable diversity of plants within the production centers, with a total of 805 varieties across 10 districts in Bogor, Cianjur, and Depok regency. Despite 76% of these production centers employing conventional procurement methods, they are sufficiently able to meet the plant needs of their users. The study recommends policy initiatives focusing on plant specifications and net pricing, establishing a real-time plant database, and mapping nursery distribution locations to enhance procurement efficiency, benefiting both consumers and producers.

Abstract

The rapid urbanisation and population growth in Bogor City has significantly decreased green open spaces from 1,982.23 ha in 2009 to 784.74 ha in 2021. This study aims to assess the extent of vegetation, land surface temperature (LST), and urban heat island (UHI) in Bogor City in 2023 spatially and develop recommendations for green open spaces development to mitigate UHI effects. Landsat 8 OLI/TIRS satellite imagery from July 20, 2023, was used to calculate the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), LST, and UHI intensity. The relationship between vegetation indices and LST was analyzed using RStudio to determine the required green open spaces area for reducing surface temperatures. Results showed that regions with high vegetation density had lower LST than urban areas. The UHI intensity in Bogor City was quantified by comparing urban and non urban temperatures using a 5 km buffer zone. Regression analysis revealed a significant negative correlation between vegetation indices and LST. The findings suggest that increasing green open spaces through strategic planning and development can effectively mitigate UHI effects in Bogor City, improving urban environmental quality and residents' well-being.

Abstract

Greenbelt and green infrastructure are still very limited in Jakarta. Transjakarta Corridor 8 Harmoni - Lebak Bulus covers Central Jakarta, West Jakarta, and South Jakarta which are government centers and densely populated settlements. The high activity in the area causes an increase in transportation flows and greenhouse gas emissions. The transportation sector is the highest contributor to CO2e emissions in the capital city, thus reducing environmental quality, especially the greenbelt in Transjakarta Corridor 8. The assessment of ecological functions in this study consists of 7 variables, namely noise reduction, pollution reduction, air humidity, view control, glare control, direction and accident prevention. The research location is divided into 5 segments with the analysis method used, namely the assessment of ecological function aspects and the formulation of recommendations based on Hierarchical Process Analysis. The results of the assessment on ecological functions with noise-canceling variables were (Polyalthia longifolia) Glodongan Tiang, (Casuarina sp.) Spruce, (Acacia auriculiformis) Acacia, and (Archontophoenix alexandrae) Alexander Palm. The results of the pollution reduction assessment of each segment are dominated by vegetation types (Mangifera indica) Mango, (Polyalthia longifolia) Glodongan Tiang, (Carbera odollam) Bintaro. Based on the results of the questionnaire, the AHP assessment weight was obtained. The combined AHP results show the highest priority scale for the evaluation recommendations of this research is Pollution Reduction as the most important variable with a weight of 0.348, the second rank is Accident Reducer with a weight of 0.300, the third rank is Glare Control with a weight of 0.150. The combined results of 3 experts produce a consistency ratio value of 0.05, the consistency ratio value of 0.05 is smaller than 0.10 so it can be said to have met the consistent requirements.
