The Ciliwung River, the main river in the capital, has improved in terms of water quality, according to Environment and Forestry Ministry research into 221 spots in the river.
The ministry’s pollution and environmental damage control director general, Karliansyah, said the water quality had improved since research was conducted in 2017, and shrimp, an animal that required clean water, were found to be alive and well in the river.
“Even if shrimp are found in the river, other biota must be alive there as well. This is the proof of the community’s hard work, without it, this would not be possible,” Karliansyah said on Sunday in a written statement during an event called Ciliwung Day.
The event was held by the Clean Ciliwung Movement (GCB) to encourage residents to help clean up the river.
GCB head Peni Susanti said this year's event was held at the GCB headquarters in Karet Tengsin, Tanah Abang, Central Jakarta, with activities such as the launch of the Sahabat Sungai GCB movement, a hydroponic vegetable harvesting party, a river cruise, a water filtration demonstration and a local waste management equipment demonstration.
The event was also attended by officials from the Public Works and Housing Ministry, the Jakarta administration, Jakarta-owned companies, the Ciliwung Care Community and other stakeholders.
