Status Kontaminasi Fisik dan Kimia di Teluk Jakarta periode 2015-2021

Abstract

Status of Nutrients, Dissolved Oxygen, Suspended Total Solids and Emerging Contaminants in Jakarta Bay from 2015 to 2021. Coastal regions in Indonesia are rich in natural resources and have a strong attraction for the local population. As a result of increased industrial, agricultural, and development activities on land, anthropogenic pressures in the region are particularly severe. Jakarta is one of the coastal cities that requires special attention. Based on five years research data, this paper attempts to examine the status of contamination from physical and chemical parameters of water in the seas of Jakarta Bay (2015-2021). Furthermore, the latest data on paracetamol and microplastics in 2021 were also examined and compared to prior studies. The Jakarta Environment Agency data of total suspended solids, dissolved oxygen, nitrates and phosphates from 11 estuaries and 23 sites in the Jakarta Bay were used on the research. The physical characteristics of water chemistry at low tide are higher than at high tide because input factors from the river. The phosphate and nitrate levels have exceeded the 0.015 and 0.06 mg/L, respectively. During the eastern season, TSS in Kamal and Angke estuaries reached 186 and 255 mg/L, respectively. Muara BKT, Marunda, Cilincing, and Sunter have DO levels of less than 5 mg/L. Increased distance from the estuary is related to lower levels of TSS, dissolved oxygen, phosphate, and nitrate. Paracetamol level was measured to be 258.5, 222,77, and 5,069 ng/L at Angke, Ancol, and Cengkareng, respectively. To mitigate the threat of environmental risks, the addition of paracetamol and microplastic parameters must be addressed in monitoring and regulation of the safe limits of both parameters
