Supervisors : Dr.-Phil Arinafril va n Dr Ho Ngoc Son tn to ABSTRACT gh p ie Pollution of surface water in any parts of the world becomes one of the most nl w important environmental problems we are facing nowadays Many studies showed d oa that polluted water can deteriorate and degrade water quality and then become lu nf va an limiting factor for the use of water for many purposes Planktons are the main the primary producers which can be easily found in all kinds lm ul of water bodies Plankton community is firstly influenced and involved in water z at nh oi pollution As planktons are very sensitive to the chemicals in water, the functions of planktons as the food source for many aquatic animals restrict z gm @ The present study focused on phytoplankton species composition in Musi River, co l Palembang, Indonesia, where alongside the river many industries were hosted Two m water and plankton samplings were carried out to collect planktons from six an Lu selected sites or stations, i.e soy sauce industry, crumb rubber industry, ship dock, va regional drinking water company, cement industry and coal stockpile from n ac th VI si November 7, 2014 to November 16, 2014.The physicochemical parameters were Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), pH and Total Suspended Solids (TSS) The study also included Biochemical Oxygen Demand (BOD5) The result showed that at every station the population community of planktons varied Several planktons were found at one station, and were not found at the other stations For the first observation the number of plankton species found was 22, but for the second observation was 39 species The most abundant planktons found lu an were Ankistrodesmus acicularis (Monoraphidium aciculare) and Ankistrodesmus n va angustus with 150 individuals and 83 individuals, respectively, for first observation, tn to and Ankistrodesmus acicularis, Striatella interrupta, Koliella Longiseta with 300, gh p ie 217 and 166 individuals, respectively, for second observation nl w The study concluded that discharged wastewater from industries contributed d oa significant effect on the plankton community nf va an lu Keywords: Planktons;

PLANKTON COMMUNITY STRUCTURE, DIVERSITY INDICES, AND SIMILARITY RELATIONSHIP WITH REFERENCE TO INDUSTRIAL WASTEWATER POLLUTION BY USING CORRESPONDENCE ANALYSIS I Introduction 1.1 Rationale of the study Planktons are composed of phytoplankton and zooplankton which are typically found near the surface in aquatic environments Planktons form the most lu sensitive components of the ecosystems Phytoplankton plays a vital role in primary an n va production They also play an important role as food for herbivorous animals tn to (Reddy, et al., 2013) Zooplankton plays an essential role in water ecosystems p ie gh including river The planktonic animals take part in the transformation and circulation of organic matter (Ejsmont-Karabin et al., 2004), regulate the biomass of w oa nl phytoplankton (Lair, 2005; Kentzer et al., 2010) and provide food for fish, d especially for their larval stages and for fish fry (Pourriot et al., 1997) an lu Furthermore, the phytoplankton serves as a producer in the food chain Their nf va lm ul productivity depends upon the quality of water Many species of zooplankton are z at nh oi primary consumers and feed on phytoplankton, thus playing an important role in energy and transfer In a water ecosystem, the diversity of phytoplankton can z influence the diversity of zooplankton, or vice versa and both can be affected by the @ l gm environment factors (Chou et al., 2011) Companies which produce goods and m co directly discharge wastewater to the river are responsible for disturbance and an Lu diversity of plankton In fact, water quality is a strong determinate of phytoplankton and zooplankton dynamics, as well as diversity in aquatic system (Nasrollahzadeh n va et al., 2008; Ramdani et al., 2009) ac th si eutrophication levels and resulted in inconsistent and confusing patterns (Arhonditsis et al.,1998) These indices exclusively express the richness and variety of natural ecological communities (diversity indices), the equitability of species abundance in the sample/community (evenness), or emphasize the role of the most important species (dominance) (Washington,1984) Apparently, the multi-component nature of the similarity indices formulations, incorporating most of the above information along with the lu an divergence of these structural characteristics from the baseline conditions, n va enables the identification of even small quantitative or qualitative differences in tn to the trophic status (Arhonditsis, et al ,2003) gh p ie The first is the Shannon-Weiner Species nl w Diversity Index is calculated by taking the number of each species, the proportion d oa each species is of the total number of individuals, and sums the proportion times the lu nf va an natural log of the proportion for each species Since this is a negative number, we then take the negative of the negative of this sum The higher the number, the higher is the lm ul species diversity In the ideal situation, one should compare populations that are the z at nh oi same size in numbers of individuals (Nolan, et al., 2005) It is explained by the formula: z gm @ H = -∑ (Pi * ln Pi) co l where, m H = the Shannon diversity index an Lu Pi = fraction of the entire population made up of species i (proportion of a n ac th 36 va species i relative to TOTAL number of species present, not encountered) si S = numbers of species encountered On this experiment, Shannon index is a diversity index of species present in the stations in Musi River The second is Berger-Parker’s index This index expresses proportional importance of most abundant species This index was proposed by (Berger and Parker, 1970) and developed by (May, 1975) With simple calculation = d (James and Danoff-Burg, 2003) The formula: d= Nmax/N The reciprocal of Berger-parker Index is commonly used An increase in 1/d lu an corresponds to an increase in diversity and a decrease in dominance (McDonald, et n va al.,2010) to gh tn The third is Pileou’s index p ie Species evenness refers to how close in numbers each species in an nl w environment area Mathematically it is defined as a diversity index, a measure of d oa biodiversity which quantifies how equal the community is numerically (Mulder et lu nf va an al., 2004) Table 15: Diversity Indices lm ul Station 2 Individuals 268 117 117 166 67 101 Dominance_D 0.13 0.30 0.30 0.18 0.37 0.33 Shannon _H 2.17

z at nh oi Crumb rubber Soy sauce 0.28 m co l 0.78 an Lu n va ac th 37 si Shannon’s index Table 15 showed that in the first observation the highest diversity belonged to Soy sauce with 2.17 and the lowest diversity belonged to ship dock with 1.05 In the second observation the highest diversity belonged to PDAM with 2.32, vice versa was ship dock with 1.25 Indeed, ship dock was a station which was least diversity in all stations To answer this question, water analysis results could show it It was very clearly that Total Suspended Solids (TSS) in ship dock (50.8) exceeded standard compared with PDAM and soy sauce It means water quality in ship dock lu an was dirtier than other stations Ship dock was an area which discharged oil, paints, n va wastewater with high concentration of heavy metals and some toxins such as lead, tn to iron, etc, this toxic directly affects to planktons and organism in River gh p ie Berger-Parker’s index nl w Ship dock illustrated dominance of phytoplankton and zooplankton with 37 d oa and 33 percent perspective follow the first and the second observation which most lu nf va an of species could find in this station However, cement was less abundant with approximate 20 percent of species which could find in here lm ul Evenness (Pileou’s index) z at nh oi In the first observation, evenness belonged to Stock pile with and it also belonged to Crumb rubber in the second time with 0.97 On 16 November 2014 z gm @ when the second samples were taken, the night before had a heavy rain, it changed co l water qualities Some parameters were changed, so evenness was different in m times However, in stock pile station, concentration of BOD5 was exceeded in the an Lu first observation with 3.25 compared standard and in Crumb Rubber, COD was 15 va mg/l compared with 10 mg/l standard COD and BOD5 exceeded that mean n ac th 38 si concentration of organic and inorganic in water also surpassed standard On this condition, some species had same environmental condition could adapt and develop but the others are not It means all activities in 6stations were caused the different diversity of plankton communities in Musi River lu an n va p ie gh

between the plankton community structure and water quality parameters based on physicochemical and biochemical parameters The relationship was determined with reference to industrial wastewater pollution Results from the study showed that activities of several industries alongside Musi River influenced the diversity of planktons as the result of deterioration or degradation of water quality The most lu an concentration appearence of Helicostomella sp and Nitzschia brebissonii in PDAM n va or Diatoma anceps in Cement company showed the different diversity indices of tn to planktons in different stations in Musi River However, the wastewater discharged gh p ie into the river which was still adapted with existence of planktons The diverse and nl w convergence of the plankton numbers have likely resulted in the observed stations d oa which could have increased pressure factors, such as wastes dumped direct to the lu 5.2 Further research nf va an river from domestic and industrial wastes without any treatments lm ul Research was conducted in a short time between November 7, 2014 and z at nh oi November 16, 2014 It could not show differently in plankton community structure in a long time which changes from dry season to rain season Furthermore, z gm @ parameters were analyzed which were still limitations in BOD5 , COD, TSS, pH and co l DO The limitation of parameters led to the lack of information about water quality m which directly affected to plankton communities So, research needs to open in a an Lu long time or several years and water analysis also need to analyze
