NOVELTY - Leach hole infiltration biopori (LRB) method involves: creating cylindrical holes into soil by drill biopori, where hole diameter is 10-30 cm and depth is 100 cm to not greater than depth of groundwater with distance between holes of 50-100 cm; strengthening mouth around LRB holes with mortar to 2-3 cm wide and 2 cm thick; filling LRB holes with organic waste from crop residues from tree leaves, grass clipping from yard or kitchen waste; further adding organic waste into hole when it is reduced or shrunk due to weathering process; and taking compost formed in LRB maintenance hole at end of each season.    USE - As leach hole infiltration biopori (LRB) method, and as tool used for forming biopori drill to make LRB hole (all claimed).    ADVANTAGE - The hole infiltration biopori (LRB) technology provides appropriate diffusion method technology for making holes by biopori drill, increases rate of infiltration of rainwater into ground, so does not waste flows on surface which may cause flooding in wet season and drought in dry season, and also inhibits outbreak of disease carried by mosquitoes such as dengue hemorrhagic fever and malaria. Utilization of organic waste can also help to overcome problem of waste disposal which often results in pollution, emission of greenhouse gases (CO2 and methane), blockage of drainage channels and breeding of flies and mice carriers of germs. The resulting compost can be harvested to enrich soil.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a tool used for forming biopori drill to make the LRB hole, comprising: handle (1), connecting rod (2) with drill stem, and drill (3), where handle and connecting rod are made of metal with hollow spherical diameter of 2-3 cm, handle has length of 30-40 cm and has edges along 10-15 cm of rubber layer (4) to provide non-slip grip to handle that makes handle more comfortable, while holding and rotating drill, connecting rod (2) that connects drill and handle has length of 100 cm and contains information about size of drilling depth, drill is made of metal with thickness of 3-4 mm, width of 3-4 cm, length of 20 cm and width (diameter) of 10-30 cm, and handle and drill are associated with connecting rod by welded or bolts.    DESCRIPTION OF DRAWING(S) - The figure shows the drill biopori.    Handle (1)    Connecting rod (2)    Drill (3)    Rubber layer (4)
