TEMPO.CO, Jakarta - The DKI Jakarta Environment Agency (DLH) confirmed that the mass death of broomfish in the Kalibaru River, Kramat Jati, East Jakarta some time ago was not due to the waste of the sacrifice."If the cause of death is suspected to be the disposal of sacrificial waste, then this could happen to many rivers in DKI Jakarta," said Head of the DKI Jakarta Environmental Service Asep Kuswanto in his statement in Jakarta, Friday, July 29, 2022.This, said Asep, was based on a study conducted by his party in collaboration with the Environmental Research Center of the Bogor Agricultural University (PPLH IPB) to investigate the cause of the death of broom fish in the East Kalibaru River, Kramat Jati, East Jakarta."However, because the mass mortality of fish only occurred on a local scale in one section of the East Kalibaru River, there is a possibility of unusual events in the form of waste disposal with a very large discharge or a very high concentration of waste, which then spreads directly into the river section which can lead to a caused a drastic change in water quality, so that it became the cause of mass death of broomstick fish that live in the area," he said.For this study, Asep said that after the mass death of broomstick fish in the East Kalibaru River on July 11, 2022, a team from the DKI Jakarta Provincial Environment Service conducted an investigation by taking samples of river water at the scene on the same day which were then taken to the laboratory.
