Nabila Munaa Isni Nurruhwati P. S. Y. Lintang M. S. Yuniarti <p>Tunda Island has become one of the marine tourism spots that is much considered by tourists because it has good coastal ecosystems. To find out the suitablecondition of Tunda Island waters, benthic foraminifera were used in this area. Foraminifera have the potential to be a bioindicator, which can be seen from the distribution, simple anatomy of the body and its ability to form hard shells. The purpose of this study was to determine the abundance and diversity of foraminifera based on shell walls on the surface of the coastal sediments of Tunda Island. This research was conducted on August 2019. Six samples were used in this study to analyze the abundance and diversity of benthic foraminifera based on test walls on the coast of Tunda Island. The analysis showed that only 2 sub-orders were found, namely <em>Rotaliina</em> and <em>Miliolina.</em> The most common sub-orders found in all studied stations are the <em>Rotaliina </em>with an abundance of 55% and 45% for the <em>Miliolina.</em> Calculation of community structure with diversity values ranging from 1.55 to 2.24 and dominance values ranging from 0.13 to 0.38 indicate that environmental conditions are under pressure both naturally and anthropogenically.</p> 2020-06-01T00:00:00+00:00 ##submission.copyrightStatement## Distribution of Heavy Metal Lead (Pb) in Water and Plankton on Floating Net Cage Area with Different Density at Cirata Reservoir, West Java 2020-05-30T10:26:31+00:00 Dhandy Alfhian Prabangasta Zahidah Hasan Izza Mahdiana Apriliani Herman Hamdani <p>Cirata Reservoir mostly functions as a Hydroelectric Power Plant (PLTA) and the location of fish farming with the floating cage system (KJA). Utilization of reservoirs for fish culture in Cirata Reservoir has exceeded the capacity determined by the government. This causes changes in water quality in the waters of the Cirata Reservoir and affects the concentration of heavy metal lead in the waters. The purpose of this study was to determine the distribution of heavy metal lead (Pb) that exist in the KJA with different densities in the Cirata Reservoir. This research was conducted on 3 November-8 December 2019 at Cirata Reservoir with sampling stations in &nbsp;Jangari, Maleber and Patokbeusi. The method used in this research is purposive sampling. The results of the physical-chemical parameter research show that the water temperature at the three stations ranges from 31.9<sup>o</sup>C-34.5<sup>o</sup>C, air temperature 27<sup>o</sup>C-32<sup>o</sup>C, transparency 53.5-76 cm, pH 6.87-7.67, CO<sub>2</sub> 8,4-16.8 mg/L, BOD 1.1-20.5 mg/L and DO 5.83-9.72 mg/L. The results of Pb measurements in water ranges from 0,001 to 0,029 mg/L. Pb measurements in plankton ranges from 0.001 to 0.039 mg/L. Pb bioconcentration factor values ​​range from 1.27 - 2.40. These &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;results indicate that aquatic organisms in the Cirata Reservoir can accumulate metals in their bodies.</p> 2020-05-30T00:00:00+00:00 ##submission.copyrightStatement##
