Sempu Island is a nature reserve that has fringing reef with percentage of living coral cover almost constant 37% from 2009 to 2016. Coral massive Porites lutea in this area has a growth rate about 1.09 cm/yr. in average and almost similar with others. Coral massive growth rate can be monitor through their skeletal annual banding. They have two type annual banding, low density for slow growth coral skeletal and high density for fast growth rate of coral skeletal. In this banding coral can record any environmental condition such as sea water temperature, tides and heavy metal. The aim of this research was to know the concentration of copper in Sempu Island Nature Reserve in the past used ICP-OES. The result showed that the Cu concentration in P. lutea skeletal band from 2009-2016 were: 5.213; 6.403; 5.825; 6.511; 6.132; 6.403; 6.467; 6.22 mg/kg. The coral skeletal can absorb the pollutant for hundred years, and it will give important information for palaeo environment that can used for climate modelling in the future.

Coral reef is a massive natural building block that mainly composed of hard coral. In ecological view coral reef is the center of biological activity for shelter, foraging and feeding place. Porites lutea is a common coral in reef flat area such as in Pantai Kondang Merak. This coral can form a massive with hillocky colony surface and has a slow linear extension rate, that made this coral has long longevity. The annual growth band of coral skeleton provide information of pollutants in the coastal extending back over several years ago due to ability of coral aragonite traped trace metal from environment. The aim of this research was to determine the concentration of trace metals of Cd, Cu and As along with the coral annual banding. The heavy metals detection was performed using ICP-OES (iCAP 7400 Series). The concentration of Cd, Cu and As in sample 1 (KM1) were 2.236 mg/kg, 9.726 mg/kg, and 2.474 mg/kg, while sample 2 (KM2) were 1.989 mg/kg, 19.157 mg/kg, and 2,064 mg/kg respectively. Two ways mechanism of trace metals to be trapped in the coral skeleton are by direct mechanism when trace metals in a form dissolved ion that were uptaken by coral then stored into coral skeleton and by indirect mechanism when particulate metals ingested by plankton then eaten by coral through coral tissue. The tracing of heavy metal in coral is provided important information of environment condition of the sea from 2009 - 2015 that may be used for authority decision regarding pollutant ambient in the sea environment.

Nuclear analytical technique instrumental neutron activation analysis was employed for the multielemental analysis of sediments collected from Cisadane estuary. This analytical technique provides concentration of 20 elementswhich consist of heavy metals and rare earth elements simultaneously. Two sediments cores were collected using core sampler for determining the distribution of all elements in the depth profiles of sediments. Sediment cores were subdivided into 2 cm increment, dried and sent to reactor for irradiation using thermal flux of ?1013 neutrons.cm-2.s-1 for 20 minutes in Research Reactor Siwabessy, National Nuclear Energy Agency (BATAN), Serpong. Irradiated samples were measured using a multichannel analyzer (MCA) gamma spectrometer coupled with high purity germanium detector. Analysis of particle size was done since uptake of heavy metals by sediments is particle-size dependent. The results are presented and discussed.

Muara Sungai Way Belau merupakan daerah pemukiman dengan jumlah penduduk yangsangat padat. Muara Sungai Way Belau sebagai daerah yang dekat dengan tetripat wisata,lahan budidaya dan tambak serta sumber mata pencarian warga yang tinggal disekiiarMuara Sungai Way Belau menyebabkan daerah tersebut memiliki potensi peningkatanpencemaran lingkungan tenitama logam berat seperti Pb dan Cd. Penelitian ini bertujuanuntuk mengetahui konsentrasi logam berat dan mengkaji geokronologi yang terkandungpada sedimen di Muara Sungai Way Belau. Penelitian ini telah dilaksanakan bulan Juli2017. Penentuan lokasi sampling menggunakan metode purposive samplfng dun prosespengambilan sampel menggunakan alat gravity core. Analisis kandungan logam beraxmenggunakan bantuan ICP-OES dan digunakan data umur sedimen sebagai data sekunder.Konsentrasi logam berat Pb dari tahun 1878-1998 yaitu 0.699- 2,119 ppm dan logamberat Cd sebesar 0,080-0,120 ppm. Kenaikan kandungan logam berat Pb dari tahun 1878-1998 sebesar 203% dan logam berat Gd sebesar 50%.
