SEBARAN KUALITAS AIR PANTAI UTARA JAKARTA PASCA REKLAMASI DI PERAIRAN TELUK JAKARTA

Abstract

Jakarta Bay is a region directly affected by many activities of the metropolitan city DKI Jakarta so that becomes meet the place from many various pollutant compounds from DKI Jakarta. Reclamation activities also contribute to add burden on the Jakarta Bay. The purpose of this study is to explain the current condition of the waters through the distribution of water quality in North Coast Jakarta after reclamation activities. This research was conducted by to compare condition of water quality in October 2018 during after reclamation activity with previous research water quality in September 2014 before the reclamation activity in Jakarta Bay. This results showed temperature conditions is 28-31 ºC, salinity is 25,42-35 psu, acidity (pH) is 7,2-8,6, total suspended solid (TSS) is 1-216 mg/l, Dissolved Copper (Cu) is 0-0,092 mg/l, and Zinc (Zn) is 0-0,280 mg/l. While previous research at pre-recalamation showed temperature conditions is 28,9-30 ºC, salinity is 29,5-30,6 psu, acidity (pH) is 7,8-8,1, total suspended solid (TSS) is 25-68 mg/l, Dissolved Copper (Cu) is 0,001-0,005 mg/l, and Zinc (Zn) is 0,003-0,097 mg/l. There is artificial islands causes the supply of material from the land into the sea to be retained in the coastal area and reduce the current speed so that there is a decrease in the ability of flushing time and the water quality concentrated in the coastal area continuously. Finally, this condition  results concentration of water quality at post-reclamation more high than before the pre-reclamation in Jakarta Bay.
