Abstract

The objective of this research was to know the concentration of Pb, Cr, and Hg in Fish in the Ciliwung River. The observation of Heavy Metals concentration in Fish showed that only Hg in internal organ of Demersal Fish was significantly different according to the location and replication (P < 0.05), while Heavy Metals of Pb and Cr in Demersal and Pelagic Fish were not different according to the location and replication. It means that human activities such as industrial, settlement, agriculture and transportation along the Ciliwung River affect adsorption/absorption of Hg by Fish. Generally, Pb, Cr, and Hg concentration in the internal organ of Demersal and Pelagic Fish were higher than in the Fish Meat, because internal organ are the target organ of Heavy Metals substances in Fish. In general, metal concentrations of Pb, Cr, and Hg in the meat and organs of Demersal Fish were higher than that in the meat and organs of Pelagic Fish. This was due to the activity of Demersal Fish that forage and are active in bottom waters close to sources of heavy metal pollutants (sediment). The Result of observation show that in general, the contribution of human activities in the DKI Jakarta area to the presence of Pb, Cr, and Hg in the waters, sediment and Fish of the Ciliwung River was greater than in the Bogor and Depok areas.

Abstract

The sophisticated communications could be a tool as a driver to increase of the illegal wildlife trade. Since 2012 there has been a shift in the trend of illegal wildlife trade from the offline market to the online market (advertising, e-commerce and social media). This study aims to determine the role of new media in the dissemination of Indonesian Council of Ulama (MUI) Fatwa No. 4/2014 about The Protection of Endangered Species for the Balance of the Ecosystem (illegal wildlife trade fatwa). The research was carried out in April–August 2020 through the new media Facebook. Collecting wildlife trade data through Google trends for a period of 5 years (2015-2020). Google trends are used as a basic reference in determining targets for video dissemination through Facebook. The approach used is by using research methods through new media, content analysis resulting from video dissemination (such as impressions, engagement, opinions, and feelings). The results of the study show that new media can be an effective medium in conveying and developing conservation messages, particularly to reduce the illegal wildlife trade in Indonesia.
