Abstract

Rehabilitation of coastal areas can be done with soft and hard mechanisms. Rehabilitation by hard structure in mangrove areas is usually done by using break water or groin. Used tire can be used as material because it is cheap and easy to applied, but unfortunately still contradictory in pollution potential. The objective of this study was to analyze the environmental quality of coastal area of Tapak mangrove based on the Zn distribution and biomagnification levels in the environment. The study was conducted in the mangrove area of Tapak which already build a break water from used tire in July 2016. The study was observational with the sampling taken from 4 stations and 7 objects, namely in water column, mud substrate, algae, fish, shrimp, oyster and mangrove root. Data analysis was performed by descriptive and statistical analysis to measure the content of Zn in these objects. Besides, it also carried out measurements of physico-chemical factors, i.e., temperature, dissolved oxygen (DO), turbidity and pH. The results showed that the smallest Zn content was found in water column with values between 0.002 to 0.004 mg/lt. This is still lower than the national sea water quality standard of 0.1 mg/l. The greatest value was found in mud substrate of front estuary which reached 167,992 mg/kg. Biomagnification in biota of all objects, including the consumption (fish, shrimp and seaweed) were high over than 1000. The highest bioaccumulation occurred in mangrove plant followed by seaweed; whereas the smallest value was found in oysters. It is advisable to reduce the Zn content in the environment by using a soft rehabilitate mainly mangrove plants. It is also recommended to measure number of mangrove stand of mangrove which is appropriate to reduce such impact in pond water. Keywords: Zn, Distribution, Accumulation, Mangrove.
