Study on green concrete (porous concrete) sustainability to support sustainable construction in Indonesia

Abstract

Currently, the implementation progress of green concrete (porous concrete) is still very slow. The sustainable construction launched by the government has also not received a positive response from the construction sector. Green Open Spaces (RTH) and urban spatial planning in Indonesia have not accommodated the type of water-friendly pavement (porous concrete). Buildings that must meet the 30% of Green Base Cooeficient (KDH) also have not included the criteria for water-friendly concrete pavements. From the results of the Multi-Dimensional Scaling (MDS) analysis using Rapfish-R, it is known that the sustainability status of porous concrete is at a score of 71.9 (sufficiently sustainable). There are no leveraging factors from the ecological dimension because this pavement is proven to positively impact the environment, especially for groundwater reserves. Leverage from economic dimensions, i.e., added value for customer, durability, and installation costs. Institutional dimensions, i.e., application of eco-labels, product standards, and criteria for RTH and KDH. Socio-technical dimension, i.e., public understanding and perception, certification scheme, the role of media, design, and maintenance. From these leveraging factors, the strategy and roadmap for supporting sustainable construction related to green concrete applications can be formalized.
