In recent years, many studies have examined the impact of anthropogenic pollution from industrial development on the population of organisms. Benthic ostracoda, the objective of my study, can be used as sensitive indicator of anthropogenic pollution.
Jakarta Bay is located in the north of Java, close to Jakarta, the largest city in Indonesia. Many rivers flow into Jakarta Bay, including the Ciliwung, Citarum, Kali Angke and Dadap. Yatim et al (1979) reported heavy metal pollution in the Kali Angke and Dadap rivers. Hutagalung et al. (1987) found that such pollution originated from waste waters from industry. Pollution is more severe in the western part of Jakarta Bay than in the east.
In the last decade, changes in land use in Jakarta and surrounding area have increased rapidly. Developed land use in Bekasi area in 1993 had increased 7.7 % compared with 1988, whilst in Jakarta the increase was up to 20% (Tommy Firman, 1997). Changes in land use cause decreased environmental quality and disruption of ecosystems. Only a few species have been able to survive and develop in this area. Furthermore, environmental degradation produced by pollution can cause change in organic and carbonate contents. Changes in Jakarta, including land use changes, will impact on the sedimentation patterns in Jakarta Bay by increasing sedimentation rates.
The aim of my study is elucidate the history of impacts on ostracode assemblages produced by anthropogenic pollution in Jakarta bay. The results of my research will provide new information on the use of ostracodes as indicators of anthropogenic pollution in Jakarta Bay.
This model will be applicable to other polluted areas in coastal Indonesia.
