Using Bio-Pore Infiltration Hole to Reduce Flooding in Densely Population Communities of Jakarta and Surrounding Area

Along with the family's improved economic situation and the need for more space, the lots that once had much open space began to shrink as residents expanded the land built in their homes. In the end, no land was left open to absorb rainwater into the ground. Stagnant rainwater is a common environmental problem during the rainy season. As a result, some watersheds need to reduce standing water, reducing environmental damage and residential unrest. In Jakarta and densely populated urban areas, space for water infiltration is minimal. A bio-pore infiltration hole is an alternative solution that acts as an eco-drainage system. This method uses organic waste to increase the water infiltration rate into the soil. Therefore, this study aims to investigate the effectiveness of bio pore infiltration holes in reducing flooding. This method can potentially increase field permeability and soil infiltration rate 3-inch, 4-inch, and 5-inch diameter PVC tubing are used to make bio pore infiltration holes. The efficiency of bio pore technology in PVC pipes with various infiltration hole diameters has the highest value of 70.6%, increasing the field permeability to 95%.
