The objectives of this study were to clarify and evaluate the water quality of a number of rivers in East Kalimantan province of Indonesia. For this purpose, our study successfully utilized the benthic macroinvertebrates diversity as well as physical-chemical parameters of river’s water. For instance, based on the values of Average Score per Taxon (ASPT) and the National Sanitation Foundation-Water Quality Index (NSF-WQI), Karang Mumus River was categorized as polluted with Chironomus sp. and Melanoides tuberculata as codominant taxa. In addition, Jembayan River exhibited doubtful or moderate quality containing M. tuberculata and A. parvula as codominant taxa. However, Pampang River was found to be the cleanest river with Odonata and Baetidae families as codominant taxa.

The zone of Losari Coast is an icon of Makassar city, however increase activity of surrounding communities causes a decrease in the water quality. Meiofauna is an effective benthic organism used as an indicator of water quality. This study assessed the meiofauna abundance and physical-chemical parameters as water quality indicator in the Losari Coast, Makassar. The sampling method in this study was purposive sampling. The resuts showed that total meiofauna abundance identified was 66791 indv.m-2, composed of 12 phylum and 91 species or genera. Stations at the estuary of the Jeneberang and Tallo River are two sites with high level of abundance, this condition allows presence of organic contaminants triggers the high growth of meiofauna in these locations. Dissolved Oxygen is below its supposed level in waters. Acidity, phosphate and nitrate content at some of research stations exceed the threshold of their allowed presence in waters set by Indonesia government. Ostracoda, oligochaeta, polychaeta, tunicata and ciliophora are phylums with a high level of abundance, because the phylum has  high adaptability to pollutant. Good water quality is indicated by a variety of biota living in the waters, the range of diversity and uniformity indices shows that meiofauna species are categorized highly diverse and evenly distributed. The dominance index shows that there is no species was dominant, except stations around  Losari reclamation project. Temperature, current velocity, depth, brightness, salinity, pH, DO, nitrate-seawater, and phosphate-seawater correlate with meiofauna abundance. The results as a consideration for the management or monitoring of coastal environments.

Pesisir merupakan kawasan yang rentan mengalami penurunan kualitas perairan akibat masuknya bahan-bahan pencemar hasil aktivitas antropogenik dari daratan. Penelitian ini bertujuan untuk untuk mengkaji kualitas perairan berdasarkan keanekaragaman meiofauna dan parameter fisika-kimia di pesisir Losari, Makassar. Selain itu penelitian ini dilakukan untuk menganalisis pengaruh parameter fisika-kimia terhadap keanekaragaman meiofauna di dasar perairan. Penelitian ini bersifat kuantitatif dengan teknik pengambilan data secara purposive sampling. Status kualitas perairan di pesisir Losari dikategorikan sebagai perairan yang tercemar berat, hal ini didasarkan pada tingkat keanekaragaman spesies meiofauna yang sangat rendah dan sebagian besar parameter fisika-kimia perairan yang tidak memenuhi baku mutu yang telah ditentukan oleh pemerintah RI melalui Kep. MLH. No. 51 Tahun 2004. Kecerahan, DO, Suhu, kedalaman, salinitas, dan nitrat sedimen merupakan parameter fisika-kimia yang berkorelasi positif atau berpengaruh terhadap tingkat keanekaragaman meiofauna. Adapun parameter lingkungan perairan yang berkorelasi negatif terhadap tingkat keanekaragaman meiofauna di pesisir Losari, diartikan sebagai hubungan yang tidak menguntungkan. Kondisi ini terjadi akibat meiofauna merasa terganggu atas sebaran fosfat sedimen, nitrat air laut, fosfat air laut, dan pH yang tidak memenuhi baku mutu air laut.ABSTRACTThe Coastal zone are susceptible to decreasing water quality due entry of pollutants from anthropogenic activities in the mainland. This study assessed water quality based on meiofauna diversity and physical-chemical parameters in the Losari coast, Makassar. Furthermore, this study was to analyze the physical-chemical parameters effect on the diversity of meiofauna at the seabed. It employed a quantitative approach with purposive sampling technique. Water quality status on the Losari coast categorized as heavily polluted waters, this based on low level of meiofauna species diversity and most of the physical-chemical parameters does not meet the quality standards determined by Indonesian government through Kep. MLH. No. 51 of 2004. Brightness, DO, temperature, depth, salinity, and sediment nitrate are physical-chemical parameters positively correlated or influenced of meiofauna diversity level. The aquatic environmental parameters negatively correlated with meiofauna diversity level in the Losari coast are interpreted as an unfavorable relationship. This condition occurs because the meiofauna feel disturbed by distribution of sedimentary phosphate, seawater nitrate, seawater phosphate, and pH that does not meet seawater quality regulations.

Water quality parameters play an important role in intensive pond ecosystems. The purpose of this study was to determine the relationship between of water quality parameters in intensive shrimp farming of L. vannamei. This research was carried out for 95 days of intensive shrimp farming in PT. Menjangan Mas Nusantara Company, Banten, with the physical, chemical, and microbiological parameters of water as the main reference object of observation. The results showed that during the shrimp culture period the pond water quality parameter concentration was considered to be quite optimal with a stable fluctuation trend, except for the salinity and TOM parameters whose values ​​were above the water quality standard. Correlation test results state that between the physical chemical parameters have a strong and heterogeneous relationship, with the strongest parameters of pH, phosphate, nitrite, and TOM. As for the microbiological variables, the correlation of physical chemistry parameters of water is considered to be very weak, because from the correlation test results, only DO parameters showed the correlation with microbiological parameters. The conclusion of this study, that during intensive shrimp culture period, the physical and chemical parameters of water have a strong correlation of association between one another and the highest are pH, phosphate, nitrite, and TOM, but only dissolved oxygen parameters that show the relationship correlation with microbiological parameters.

Limnological aspects of the Ramsagar lake, a manmade lake of Dinajpur district was studied from January 2013 to August 2013. In this experiment, five sampling points inside the Ramsagar lake were selected and water quality parameters were analyzed fortnightly. Among different physico-chemical parameters, water temperature, dissolved oxygen, total alkalinity, total hardness, phosphate-phosphorus and concentration of Chlorophyll-a did not differ significantly except the water level and pH. A total of 29 species of plankton were recorded where phytoplankton comprised of 21 species and zooplankton comprised of 8 species. Chlorophyceae was found dominant throughout the study period followed by Bacillariophyceae, Cyanophyceae and Euglenophyceae. The highest plankton cell density was observed in the month of July and lowest plankton density was observed during the month of January. The study revealed that on the basis of physical, chemical, biological and environmental conditions the water of the lake was found to be suitable for survival of aquatic flora and fauna and also suitable for fish culture.J.
