摘要：The existence of number industries in Surabaya as the largest industrial cities in Indonesia have affects how much waste they produce and is wasted in the waters. Heavy metal Zn (zinc) is one of the ingredients in the waste. The aim of this study was to analyze the Zn content in the roots and leaves of Avicennia marina as well as sediments around it which did in triplicates from 3 stations in Wonorejo Mangrove. The method used in this study was descriptive method. Zn analysis was used the Atomic Absorption Spectophotometer (AAS) method. Water quality analysis included temperature, pH and salinity was carried out in the field. The results of the Zn analysis obtained the highest value based on the station, namely at station 1 and the lowest at station 2. Based on the samples taken, the highest Zn concentration was found in the sediment and the lowest was in the leaves. The results of the concentration of Zn in the roots, leaves and sediment at each station did not differ much. The calculated values for BCF and TF were less than 1. Analysis of the water quality of the three parameters was still in normal conditions for the growth of mangrove biota. From this research, A. marina is included in the type of mangrove that can absorb heavy metals at low concentrations. This is in accordance with the BCF and TF values obtained. Low heavy metal absorption, this type of mangrove is still classified as a phytoremediator.
