The Green Infrastructure Model Based On Waterlogging Mitigation In The Street Landscape Of Sungai Penuh City, Jambi Province

Abstract

Background: In many cases, the planning of public and social space in Indonesia is not accompanied by the planning of green open space, which is their functions as a healthy environmental balancer. One of the public spaces is the street landscape. This results in to the impact of natural phenomena such as floods, waterlogging in the rainy season, and hot weather in summer. The purpose of this study is to provide an overview of the Green Infrastructure model of roads, can also function as a place to anticipate waterlogging, flooding, air quality improvement, and human-friendly designation. Materials and Methods: The methodology was carried out through field inventory, mapping based on Shp ArcGis data, and a modified literature study. The location of the research is on roads spread across 8 subdistricts of Sungai Penuh City, Jambi Province. Results: Based on government administration and axis content, the public roads of Sungai Penuh City are categorized into class III Provincial Roads. The number of road sections in Sungai Penuh City is 49 (forty-nine) road sections. The details are that the primary collector road landscape consists of 11 road sections, the secondary collector road landscape consists of 12 road sections, and the local road landscape is very dominant, which is as many as 26 roads. The total length of the entire Sungai Penuh City road section is 51.43 km with an average width of 6 meters. Based on the level of urgency, the results of the assessment of priority sub-districts determined 31 road sections spread across Sungai Penuh District, Sungai Bungkal District, and Pondok Tinggi District as priority sub-districts for the implementation of the Green Infrastructure system. Based on hydrological calculations of rainfall for the last 20 years (2003-2023). Conclusion: The Green Infrastructure Model is prioritized for 3 sub-districts. Based on the assessment of the Green Infrastructure Implementation Indicator, two green infrastructure concepts are applied, namely Green Stormwater Infrastructure 1 (GSI 1) and Green Stormwater Infrastructure 2 (GSI 2) which are equipped with the Complete Street concept. The GSI 1 system is applied on 24 roads in Sungai Penuh City using the Stormwater Tree Trench and planter. The GSI 2 system consisting of Stormwater Bump-Out, Stormwater Tree Trench, and Stormwater Planter and the Complete Street concept will be applied on 7 roads in Sungai Penuh City
