Zoo-holoplankton dynamic between the sites are useful to knowledge with the regard to the characteristic of the areas and in relative to the community structure of zoo-holoplankton.The research conducted in the surrounding waters of Kamal village, the western part of Seram Island, Maluku Province. Zoo-holoplankton organisms collected from six-fixed Research stations consisted of different characteristics, namely stations 1 and 2 are Fish Aggregation Device placement areas, station 3 is the area for setting the lift nets, stations 4 and 6 are in front of the river mouth and station 5 is in the coral reef area. Sampling done every two weeks by using zooplankton net (diameter of 45 cm) sled with a 200 µm meshed. The result showed that the composition of zoo-holoplankton consisted of 37 genera from 8 phylum, 9 classes, and 28 families. There were about 9 genera (Calanus sp, Calocalanus sp, Acartia sp, Centropages sp, Oithona sp, Onceae sp, Corycaeus sp and Copilia sp), which found in all stations and periods. While some genera are only present at certain stations or periods (Eucalanus sp, Labidocera sp, Sapphirina sp, and Evadne sp). The abundance of zoo-holoplankton peaked at station 5 (16,332 ind/m−3) in the third period, while the lowest was at station 1 (809 ind/m−3) in the second period. Similarities indices was high between station 1 and 2 during the whole period (91%, 82% and 78%) and was low between station 1 and 6 (In the first period) and station 3 and 5. We noticed that differences characteristic of sampling areas leading to the abundance and the genera numbers of zoo-holoplankton. .

Activated carbon was produced from high-grade bituminous coal, potentially removing Cr metal in textile industrial waste. The purposes of this study were 1) getting activated carbon characteristics, 2) studying the impact of reagent concentration and activation temperature on the activated carbon characteristics, and 3) getting the isotherm adsorption equation for activated carbon developed by Freundlich and Langmuir on Cr metal. This research used an experimental method with a laboratory scale, which means the manufacture of activated carbon and a test of adsorbs power of activated carbon to the Cr metal were conducted in the laboratory. Activated carbon manufacture through carbonization process of chemical activation used reagent (NH4)3PO4, neutralization, filtration, physical activation, and cooling. At the same time, it tested the adsorption power of the activated carbon to Cr metal through activated carbon contact with a solution containing some Cr6+ ion. The update in this research was using reagent (NH4)3PO4 and the test of adsorption power of activated carbon to Cr6+ ion contained in the artificial waste. This research showed activated carbon that has been activated using reagent (NH4)3PO4 0.5 – 2 M at physical activation temperature of 825oC and has met the standard of SNI number 06-3730-1995. The best-activated carbon was produced from chemical activation using (NH4)3PO4 1 M solution and physical activation at 825oC. The best-activated carbon characteristics contained 1.27% water; 17.17% content of volatile matter, 9.39% was ash content; 73.17% contained fixed carbon, and the iodine value was 1248.30 mg/g. The best Equation of Langmuir isotherm adsorption of activated carbon to the Cr6+ produced Constant Ar = -90.0901 and Kc = -0.0075.
