Coastal areas have very broad benefits both in the ecological and socio-economic. However, due to excessive use it can also have an impact on pollution in coastal areas. Heavy metal is a pollutant that is dangerous because it has toxic to the environment if its concentration exceeds the threshold. Payung Island is a lowland area that is overgrown by mangroves. This island is in the middle betwe…
The coastal areas have very promising potential, this is because coastal areas are the natural habitat of many individuals in nature. This potential is disrupted in the form of pollution, pollutants originating from agricultural industrial activities in the upstream river in the form of zinc (Zn) and those from lead (Pb) transportation activities around the coastal area is one of the causes of …
Infectious diseases are the main cause of high mortality and disease rates in developing countries such as Indonesia and can be caused by bacteria such as Staphylococcus aureus and Escherichia coli.
