Assessment of The Antropogenic Impact on Mangrove Ecosystem and Endemic Fauna in Muaragembong, Bekasi, West Java

Abstract

The Muaragembong coast is degraded by anthropogenic factors such as pollution and ponds. The area that used to be a mangrove ecosystem is now experiencing abrasion. Trash trapped in the mangrove ecosystem also affects the ecosystem and its biodiversity. This research is descriptive in nature with the aim of knowing changes in mangrove areas through analysis of Landsat satellite imagery and identifying the causes of changes and impacts on endemic species. This research was conducted with the stages of literature study, analysis of satellite imagery in 2000, 2009, 2010, 2014, 2019 and 2020. Based on the analysis of satellite imagery, it was found that changes in mangrove area were confirmed with secondary data so that the factors that caused these changes were known. The results of the analysis show that the degradation of the mangrove ecosystem in 2017 was approximately 2800 ha and affected the existence of the Lutung Jawa (Trachypithecus auratus) as an endemic fauna in Muaragembong which inhabits the mangrove ecosystem on the north coast of Bekasi. It is currently estimated that there are no more than 50 present in the area, therefore the Lutung Jawa is considered a vulnerable species as cited in CITES Annex II 2008.
