“…Figure 2. The analysis of grain size of sediment in coastal areas in Jakarta Bay, Indonesia The low value of IVI of mangrove vegetation in all stations was likely a response to the condition of the waters in Jakarta Bay which were polluted by heavy metals, both from the land and from the waters (Table 3) (Permanawati and Ibrahim 2013;Kusuma et al 2014;Siregar et al 2016;Sinern et al 2016;Lohr et al 2017;Latief et el. 2018).…”

“…In a decade, the land cover had reduced from 340,90 ha in 1997 to 232,04 in 2006, equating 31.93% loss (Parawansa 2007). This change is mainly caused by land degradation with human as the main driver as indicated by many studies such as Permanawati et al (2013), Kusuma et al (2014), KLHK and Plarenco (2015), Breckwoldt et al (2016), Ladwig et al (2016), Simon et al (2016), Sindern et al (2016), Siregar et al (2016), Dsikowitzky et al (2018), and Latief et al (2018).…”

Abstract. Sari N, Patria MP, Soesilo TEB, Tejakusuma IG. 2019. The structure of mangrove communities in response to water quality in Jakarta Bay, Indonesia. Biodiversitas 20: 1873-1879. The waters of Jakarta Bay, which is a habitat for mangrove vegetation, have been polluted caused by many human activities such as development of housing, industry, tourism and facilities along the coast, and reclamation of man-made islands. The islands reclamation has caused changes in ocean current pattern and has impacts on material mobilization in the waters. The mangroves have experienced degradation as well since long time ago. The purpose of this research was to investigate the responses of mangrove vegetation to the quality of water in disturbed areas in Jakarta Bay to be used as baseline information for mangrove forest management in the area. Analysis of vegetation was used to examine mangrove community structure with the results were then related to the measurements on water quality using simulation modeling. The results show that mangrove forests in Jakarta Bay have an average Important Value Index (IVI) for all levels of life stage 95.7% with relative density of 28.85%, relative frequency of 29.21%, and closure relative of 38.62%. These results indicate that the mangrove forests in Jakarta Bay are under the criteria of damaged or disturbed according to the Minister of Environment Regulation. The mangrove forests were dominated by Avicennia marina, Avicennia lanata, Rhizophora apiculata, Sonneratia caseolaris, and Sonneratia alba. The average of ocean current velocity was 0.04-0.08 m/s. tides were single type with short waves generated by wind. The water discharge from 13 rivers were 205 ± 97 m3/s and the water discharge from power plant 224.9 m3/s. The heavy metal whereas The average pH was 7.75; Dissolved Oxygen 4.68 mg/L; turbidity 5 m; Total Suspended Solid (TSS) 50.95 mg/L; and salinity 6.6 ‰. The result of grain size analysis showed that most sediments obtained was in the form of silt with a mixture of little clay and sand. The responses showed that there was a reinforced pattern for pH, temperatures, rainfall, brightness, sediment, DO, and ocean current, with a trend of exponential growth in two years next of important value index of mangroves in response to water quality in Jakarta Bay. The heavy metals of Pb have concentrations of 65-104 ppm in sediments and 38-60 ppm in the water column; Zn has 150-258 ppm in sediment and 42-140 ppm in water column; Cu has 34-72 ppm in sediment and 13-30 ppm in water column; Ni has 33-39 ppm in sediment and 40-50 ppm in water column; Cd has 5.9-8 ppm in sediment and 8.5-15 ppm in the water column. The heavy metals, TSS, and water river discharge have balance-decay pattern. The amount of river water discharge entering Jakarta Bay, the heavy metals, and the low level of ocean currents cause coastal waters of Jakarta Bay to become muddy puddles that cannot flow properly. These conditions make the mangrove forest habitat becomes polluted and the mangrove vegetation degraded. Therefore, all of these things need to get serious attention so the mangrove forests can be restored and the function of mangroves can return to normal.

“…The entry of the contaminants, especially into sea waters, can reduce the quality of the waters. Besides, changing water quality, due to heavy metals deposited in the sediments, can also cause the transfer of toxic chemicals from sediments to organisms (Permanawati et al, 2013). This result is alarming since heavy metals are accumulative elements both in sediments and bodies of aquatic organisms.…”

Increasing number of industries and settlements in Banten Bay were subsequently followed by an increase in the amount of waste, whether in the form of solid, liquid or gas that can pollute the environment. One of the toxic pollutants is heavy metal.The entry mechanism of the heavy metal Mercury (Hg) and Lead (Pb) in body of the crab (Portunus pelagicus), namely through the process of digestion food. This study was conducted for 6 months, from March to August 2019, and aimed to analyze the heavy metal content levels (Pb and Hg) and the safe consumption level of the blue swimming crab (Portunus pelagicus) in the waters. The heavy metal concentration in the meat was measured through the AAS (Atomic Absorption Spectrophotometer) AA 7000 series Shimadzu. The analysis showed that the Pb and Hg contained in the blue swimming crab were still under the quality standards. Also, the bio-concentration factors of the blue swimming crab were low (<100). Water quality data observed as temperature, salinity, TSS, pH, dissolved oxygen, turbidity, and transparency stayed in the range of tolerable limits for the survival of marine organisms. Maximum weekly intake calculation refers to the tolerable limits issued by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). The JECFA recommends calculating the PTWI of each heavy metal if it accumulates in the human body for methyl mercury 1.6 μg.kg bw.week-1 and for lead not exceed 25 μg.kg bw.week-1. The safety consumption level of blue swimming crab from Cengkok Coastal water was 2.3 kg of meat.week-1 (for adults) and 0.6 kg of meat.week-1 (for children).

“…Secara umum kadar logam berat diperairan dapat membahayakan kehidupan biota laut. Adanya akumulasi logam berat dalam sedimen dapat menimbulkan akumulasi pada tubuh biota yang hidup dan mencari makan di dalam air maupun di sekitar sedimen atau dasar perairan, dan akan mencemari kehidupan biota laut, yang pada gilirannya akan berbahaya bagi manusia yang mengkonsumsinya (Permanawati et al, 2013). Sedimen berperan penting dalam menentukan kualitas air dikarenakan peranannya sebagai tujuan akhir limbah.…”

Cirebon Regency has many issues concerning the degradation of the quality of the waters sourced from community activities that dump their waste into the waters. This study aimed at determining water quality (water and sediments) District of Cirebon in terms of physical and chemical parameters. The method used in this study was quantitative descriptive analysis using primary data and secondary data designed to describe the physical and chemical conditions of the waters.
