“…(Hasani et al 2012) menyatakan bahwa peningkatan kadar nitrat mengakibatkan peningkatan kelimpahan total fitoplankton. Mulyasari et al (2003) menyatakan terjadinya blooming fitoplankton mikroskopis yang hidup di lingkungan perairan dapat menimbulkan dampak negatif. Blooming fitoplankton dapat menyebabkan kematian ikan akibat kekurangan oksigen dan pembusukan.…”

“…But so far, there is no clear threshold regarding to quantity of phytoplankton at the time of the blooming. Further that the condition of phytoplankton blooming, can occur when the quantity of abundance can be much more than the averaged quantity of phytoplankton per month [19].…”

“…The use of macronutrients by potentially toxin-containing phytoplankton (HABs), can lead to anoxia, ie the decreased and even dissolved oxygen (DO) loss in water bodies, thus, negatively impacting degradation of waters. Another impact from phytoplankton blooming is also shown after mass death, which will be described by bacteria, this process requires high oxygen consumption, resulting in dissolved oxygen concentrations depleted, resulting in conditions (anoxia) or oxygen depletion in waters [19,22] …”

Segara Anakan Lagoon (SAL), located along side of soutern coast on western part of Central Java 108°46'–109 ° 05'E; 7 ° 34'–7 ° 48'S. SAL is necessasrily ecosistem as nursery ground. This has been becoming important research relating to primary productivity. The existance of antropogenical activities around the area, is changing inrush input into lagoon. This is going to be worried about giving influences in physical, chemistry, and biological factors of the water and causing deflation in rate value of primer productivity. Rainy and dry season's variability with important impacts on the phytoplankton community structure, abundance and dynamics. Furthermore, the number of coastal ecosystems with identified eutrophication symptoms is increasing worldwide due to the increasing anthropogenic pressures. One of 1the first symptoms of eutrophication is enhanced phytoplankton biomass. Generally, Fitoplanton is important biological indicators in the process. However, high abundance of biomass phytoplankton could give harmful effect toward lagoon, they could produce toxic substances that will be accumulated, it can be endangering .The aim of the research is to determine and calculate potential species of Harmful Algal Blooms (HABs) in SAL with spastial and temporal approach. The spatial approach is done at seven different stations of ecological characteristics SAL, with representations: natural factors and the presence of anthropogenic activities. On the temporal approach (time series) for a year, it refers to the monsoon wind pattern, which are called season (western, the transitional season 1, eastern, and the transitional season 2).The results of laboratory tests are discussed descriptively. Phytoplankton sample were taken vertically using plankton nets, meshsize 25 μm. The result showed that SAL have been found and consisted of 82 species from 5 division phytoplankton: Chrysophyta, Chlorophyta, Cyanophyta, Pyrophyta, and Euglenophyta. 20 species from 9 genus were identified potential as HABs, with four genus of them were known having toxin and endangering for human (Nitzschia, Oscillatoria, Anabaena dan Protoperidinium).Whether, five genus do not produce toxins but giving deflation Oxygen of waters with anoxia condition (Chaetoceros, Coscinodiscus, Rhizosolenia, Thalassiosira, Thalassiotrix).The highest of HABS abundance is dominated during the transitional season II. On the spatial approach, antropoegenic characteristics station contribute to the whole height of HABs. Influence of rainfall, spatially, antropogenical pressure, and hydrodinamical watres causing enhancement of HABs potency.
