Analysis of the green infrastructure implementation to the enhancement of environmental support capacity (Case study: Watershed outside University of Indonesia)

Abstract

The several things to fulfil human needs are water resources, like household, laundry, industry and agriculture, the activities that reduce the availability of ground water and produce waste which makes the quality of river water decrease. This research was conducted in a catchment area outside University of Indonesia which is included in the Ciliwung watershed area which aims to increase the carrying capacity of water resources by carrying out a Water Governance approach by considering 3 aspects Place, People and Policy. The Place aspect or technical recommendations was an approach using the concept of WSUD (Water Sensitive Urban Drainage), the green infrastructure used are bioretention and constructed wetland by using ArcGIS, GitBola and SWMM for simulations of improving air quality and volume of runoff water reduction. The People aspect or stakeholders are conducted in-depth interviews or snow ball interview with stakeholders and residents in the catchment to find out responses to green technology recommendations and stakeholder responses. The policy aspect makes appropriate policy recommendations that regulate the management of liquid and solid waste so as not to pollute water bodies, to improve the condition of catchments around University of Indonesia, making policy recommendations based on the technical aspects of green technology proposals, community or stakeholder responses and also based on existing policies or regulations from the central to the regional level.

Pollutant Burden on Pollution Sources in the Wai Batu Merah Watershed, Sirimau District, Ambon City

“…The collection of data on pollutant sources was obtained from direct survey results using the saturation sampling method or census which is guided by the Regulation of the Minister of State for the Environment of the Republic of Indonesia Number 1 of 2010 concerning the management of water pollution control. to identify pollutant sources, both point sources and non -point sources in the Wai Batu Merah watershed (Negoro et al, 2021). point source and non-point source pollutants in the Wai Batu Merah watershed.…”

Analysis of flooding and nature-based solutions in the improvement of urban drainage system

“…The SWMM (Storm Water Management Model) application is a dynamic rainfall and runoff simulation application used to simulate single or long-term events and the quantity and quality of runoff from urban areas. SWMM is widely used to optimize designs, evaluate existing conditions, improve performance, mitigate flood/inundation areas, and implement low-impact development (LID) drainage systems and nature-based solutions approach [13,14,15,16,17] The objective of this study was to analyze the drainage system and evaluate the performance of the retention pond using SWMM 5.1.…”

Evaluation of Water Resources Carrying Capacity based on Ecological Footprint

“…With the rapid expand of economic globalization, the research on the quantity and quality of WR is also increasing with the increase of water shortage, and the concept of CC is introduced into the field of WR [5]. The main representative results are as follows: water availability, water quality, sewage treatment and other indicators are used as the influencing factors of urban WR CC, and the WR CC of different cities is analyzed and studied [6].…”
