TEMPO.CO, Jakarta – The status of coral reefs in the very good category in Indonesia is only 6.56% with 70 sites, a poor percentage of 36.18% with a total of 386 sites. The bad categories of coral reefs are caused by natural conditions or global climate change.

"In general, the damage is caused by global climate change.The damage can be due to nature and atropogenik.For example, natural earthquakes or tsunamis as in the Banda Sea, a population large polycarang predators and global climate change, "said the researcher, Ocean Science Research Center of the Institute of Science. Indonesia (LIPI) Giyanto in the large LIPI seminar room in Widya Graha, South Jakarta, Wednesday, November 28, 2018.
The extraction of natural corals by fishermen or coral traders has achieved the CITES Non-detriment Determination (NDF) criterion. According to the results of a study of the Oceanographic Research Center conducted in several reef mining provinces, these activities caused neither damage nor significant reduction of coral populations in the wild. .
Because of climate change, said Giyanto, the current state of coral reefs in Indonesia has changed compared to last year. In addition to the very good and bad categories, coral conditions in Indonesia in the good category were 245 sites or 22.96%, while sufficient categories were 366 sites or 34.3%.
"While anthropogenic damage is an example such as the capture of excessive imbalance, bombings and poisons, mining, pollution, sedimentation, tourism, dredging, backfilling and coastal development" continued Giyanto.
Coral reefs have great economic value, but they can be damaged and require long and prolonged treatment to restore coral reefs as before.
According to the mapping results and data from 2018 until 2017, several localities such as Nias lacked health for coral reefs because the waters were rather murky, Raja Ampat was not good neither was Wakatobi high because of the good coral cover.
Other researchers at the LIPI Ocean Research Center, Suharsono, explained that Indonesia is the center of the coral reef ecosystem, especially in central Indonesia.
"Australia has no harm caused by humans, only a bit, solely because of tourism activities." The whitening only occurs in the west of Indonesia, while East of Indonesia is never affected because of the cross flow of Indonesia able to protect the reef, "added Suharsono.
