Biography:

Dr. Noverita Dian Takarina completed her undergraduate (S1) at the Faculty of Biology, University of Gadjah Mada in 1989. After graduation, she taught Animal Anatomy at Muhammadiyah University Surakarta (1989-1990). From 1991-2000, she taught Ichtyology at University of Diponegoro. Presently she is teaching at the Biology Department, Faculty of Mathematics and Natural Sciences (Science), Universitas Indonesia. Doctoral degree was received from Bogor Agricultural University (IPB) in 2014 with a scholarship from the Universitas Indonesia. She received grants obtaining from abroad, namely Tzu Chi University and Foundation, Taiwan; the International Foundation for Science (IFS), Sweden, as much as 2 times, in 2008, IFS in collaboration with the Swiss Bank, and in 2010 IFS with the Organization for Prohibition of Chemical Weapons (OPCW), The Hague. In addition, she got grants from the Higher Learnin Education of Indonesia in the form of Fundamental Research (2007) and Competitive Research (2012), as well as from the Universitas Indonesia in the form of Leading Research (2009) and Excellent Research of Universitas Indonesia (2010). She also received an award from the Universitas Indonesia as the author of the International Journal on Marine Pollution Bulletin, published in 2004. In 2005, she presented a paper entitled Speciation of Heavy Metals in Sediments of Semarang, Central Java, Indonesia at the International Conference on Ocean Governance: Law, Policy, and Management in Townsville, Brisbane, Australia.  In 2015, she received Multidiciplinary Research Grants concerning mangrove considered as accumulator for heavy metal. In 2016, she received three PITTA UI Research Grant for phytoplankton, zooplankton and benthos as heavy metal pollution indicator, using red snapper fish scale waste to produce chitosan, and  using extract of mangroves and sea grape to inhibit melanosis on Pacific white shrimp. She has published several articles for international journal starting from 2004 at Marine Pollution Bulletin and continuously at International Journal of Marine Sciences, etc. While publication for national journal, she published at Makara Journal of Sciences at 2013. Currently, she is acting as Head of Post Graduate Program on Marine Science, Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Indonesia.

Title: Impact of Mangrove Deforestation on Heavy Metals Content in Sediments and Benthos

Abstract:

The Jakarta Bay ecosystem is influenced by mosaic of mangrove forests, industrials and settlements developed along the bay. Recently, massive anthropogenic developments have removed the intact mangrove and have caused mangrove lost its capabilities to retain pollutants for example heavy metals. Therefore, this paper aims to study the differences of heavy metals (Cu, Cr, Pb, Zn) in sediments and its impact on benthos community in Jakarta Bay. The benthos and sediments were sampled from 8 sites that represented mangrove and deforested sites and the heavy metals content were analyzed using Atomic Absorption Spectrophotometer (AAS). The community of benthos was evaluated based on the Shannon-Wiener Biodiversity Index (H’).
 
The average concentrations of heavy metals (ppm) in mangrove  sediments were 15  for Cu, 20 for Cr, 15 for Pb and 100 for Zn. Likewise, the average concentrations of heavy metals (ppm) in deforested sediments were 80  for Cu, 40 for Cr,  35 for Pb and 250 for Zn. A total of 60 benthic species that consist of molluscs, polychaetes and crustaceans were enumerated for H’. The H’ index for polychaetes ranged from 0.0. to 0.5. Meanwhile, the H’ index for molluscs ranged from 0.0. to 0.9. It is inferred that the deforested sites have higher content of heavy metals and lower benthos diversity. Other significant findings include differences on heavy metals content among  benthic species. The order of heavy metals in benthos collected from mangrove and deforested sites were found Zn>Cr>Cu>Pb with metals found to be higher in the benthic inhabitants of the deforested sites. Hence, the study provides direct evidence of the impact of mangroves deforestation on heavy metals in sediments and benthos community and recommends the importance of mangrove conservation in the future.
