Condition of major cities such as Jakarta's water catchment area which has very little ground water usage along with a very exaggerated cause a decrease in surface soil and made it difficult to get good quality and sufficient water in the region.
Thus the environmental balance that must be constantly preserved and maintained even more damaged and uncontrolled. For that needed conservation movement around made jointly by all parties and sustainable.
One way that can be taken to prevent the flow of rainwater into the gutter which then wasted to the sea is by making a hole biopori infiltration or LBR. The meaning of the definition and understanding by organisasi.org biopori hole is a hole with a diameter of 10 to 30 cm with a length of 30 to 100 cm is covered with organic waste that serves to trap the water that flows around it so it can be a source of water supply for underground water, plants in the vicinity and can also help weathering of organic waste into compost that can be used for fertilizer plants.

Objectives / Functions / Benefits / Role Hole Resapan Biopori / LRB: 1. Maximizing water that seeped into the soil thereby increasing soil water. 2. Natural composting of organic waste rather than burned. 3. Reduce standing water that cause disease. 4. Reduce rainwater that gratuitous thrown into the sea. 5. Reducing the risk of flooding in the rainy season. 6. Maximizing the role and activity of soil flora and fauna. 7. Preventing soil erosion and landslide disasters.
Places that can be created / installed biopori hole water absorption: 1. On the pedestal channels rainwater around the home, office, school, etc.. 2. Around the tree. 3. On vacant land between crops / plant boundary.
Hole Making way Biopori Resapan Water: 1. Creating a cylindrical hole in the ground with a diameter of 10-30 cm and a depth of 30-100 cm and 50-100 cm distance between holes. 2. The mouth of the hole can be reinforced with cement thickness of 2 cm and 2-3 cm wide, and provided there is no safety for small children or people who fall. 3. The hole is filled with organic waste such as leaves, kitchen waste, tree limbs, junk food kitchen non-chemical, etc.. Trash in the hole will shrink so that needs to be filled again and at the end of the dry season can be drained as a natural compost. 4. Number of holes biopori existing large and small should be calculated based on rainfall, water infiltration rate and water areas that are not absorbed by the formula = intensity of rainfall (mm / h) x broad field of water-resistant (square meter) / perlubang water infiltration rate (liters / hour) .
