"The one million biopori is one of the Jakarta LDII working programs for the next five years period," said Teddy Suratmadji, chairman of the LDII Jakarta chapter here on Sunday after opening the working meeting of the North Jakarta LDII branch.
It means that the Jakarta LDII will produce some 200 biopori holes every year, Teddy said, adding that the pilot project of the water catchments will be launched in June 2011.
According to Teddy, various organic wastes will be put into the biopori, so that the holes will connect themselves to reduce the flow of floods into sea.
Big floods normally inundate the Greater Jakarta area especially before and during the Lunar year.
The biopori that will be placed in a number of mosques, minor mosque-areas and the residential houses in Greater Jakarta are part of the benefaction of the Jakarta LDII members, he said.
The activity is locally known as Green propagation conducted in cooperation between the Jakarta LDII with Jakarta Ulema Council (MUI), he said.
The biopori will be directly conducted by the LDII self-financing effort expected to help reduce floods in 2012.
The idea of â€‹â€‹preventing floods in a simple, easy, and inexpensive way was initiated by Kamir Brata, a lecturer of the Bogor Agricultural Institute (IPB). (B003/H-NG/o001)
