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.

The Itajaí-Mirim River located in Santa Catarina, in the region of the low estuary of the Itajaí-Açu River, is the place where most of the water supplied for consumption is consumed by the Municipalities of Itajaí and Navegantes, the São Roque catchment station. This study aims to analyze the water quality in the Itajaí-Mirim river before and after the implantation of the dam in the Itajaí-Mirim river, based on a monitoring of physical-chemical parameters. The collections described in this report were carried out at six sample points, from January to December 2007, with the purpose of physically and chemically characterizing the environment in the rectified channel and, also, in the original bed of Itajaí-Mirim. The parameters measured in situ serve to assess the general state of water quality at the time of sampling. The main parameters measured, four of them deserve special attention (pH, Turbidity, Dissolved Oxygen and Salinity) and the correlated environmental parameters were flow rate and precipitation. In general, depending on the main results obtained, the analyzed waters can be classified in Class 2 of fresh waters, according to the limit values of CONAMA Resolution No. 357/05, and for the sampled period, precipitation and flow influenced the water quality.

Abstract. Taniwel D, Leiwakabessy F, Rumahlatu D. 2020. Short Communication: Density and length-weight relationship of mudskipper (Periophthalmus spp.) in the mangrove area of Kairatu Beach, Maluku, Indonesia. Biodiversitas 21: 5465-5473. Mudskippers (genus Periophthalmus) fish species inhabit mudflat, sandy beaches, and mangrove areas. Their daily activities are influenced by tidal rhythms. The aim of this research was to identify the species of mudskipper, their density, and length-weight relationship of more density species in the mangrove area of ​​Kairatu beach, Maluku, Indonesia. This research was conducted from July to August 2018, 3 sampling sites using purposive sampling technique. The physical-chemical parameters of environmental conditions (temperature, dissolved oxygen, salinity, and pH of water) were measured directly on location (in-situ), while the different mudskippers species present in the study sites were identified in the laboratory at the Pattimura University. Quantitative data on population density and length and weight of individuals were obtained for four Periophthalmus species. The physical-chemical parameters of environmental conditions in the three sampling stations were within the range of optimal values previously obtained for mudskipper species. The temperatures ranged from 30.01-30.05 oC, the dissolved oxygen ranged from 7.1-7.5 mg/L, the pH ranged from 7.3-7.5, and the salinity ranged from 5-7 ‰. The four mudskippers species identified in the sampling sites were (in density descending order): Periophthalmus argentilineatus (5.05 ind/m2), P. gracilis (1.5 ind/m2), P. malaccensis (0.4 ind/m2) and P. kalolo (0.3 ind/m2). The results of the regression analysis showed that there was no significant relationship between physical-chemical parameters to mudskipper density. The results of the length-weight relationship of the two most abundant species P. argentilineatus and P. gracilis a negative allometric length-weight relationship (b<3), while the P. kalolo and P. malaccensis indicated a positive allometric growth type (b>3).

Tigriopus fulvus (Fischer, 1860) is a benthic harpacticoid copepod of the Mediterranean supralittoral zone. The transitional characteristics of this environment forced this species to develop high resistance to changes of environmental parameters. Nevertheless, Tigriopus fulvus life-cycle is influenced from the splashpools physical-chemical parameters. In this paper, we present the results of a supralittoral monitoring performed in 2014, confirming the influence of some of these environmental parameters on population buildups. Because of recent worldwide climate change effects, a threat might have been posed on this particularly exposed organism, whose population density decreased of a sixfold value in the last 30 years. During the three pools (A, B, C) monitoring, the maximum copepod density recorded was 1456 Ind/l (September 2014, Pool C), alongside first records of extinction event for Tigriopus fulvus.

ABSTRAK Muara Sungai Cipasauran merupakan ekosistem yang dimanfaatkan oleh masyarakat setempat untuk kegiatan rumah tangga. seperti mandi, mencuci pakaian dan kegiatan nelayan. Aktivitas kegiatan tersebut menyebabkan masuknya air limbah ke saluran air sungai lainnya. Hilir Cipasauran Muara, berakhir di Pantai Anyer. Kegiatan penangkapan ikan di sekitar Pantai Anyer menunjukkan kualitas air yang relatif baik. Tujuan dari penelitian ini adalah untuk menentukan sebaran bakteri heterotrofik, bahan organik total, nitrat dan klorofil-a, serta untuk mengetahui hubungan antara variabel. Bahan yang digunakan dalam penelitian ini adalah air sampel dari 4 lokasi di muara Cipasauran ke Pantai Anyer. Penelitian ini menggunakan teknik purposive sampling. Pengambilan sampel dilakukan dengan interval dua minggu, masing-masing dengan dua kali pengulangan. Hasil penelitian menunjukkan bahwa jumlah bakteri heterotrofik  di empat stasiun berkisar antara 250-2500 cfu/ml, kandungan bahan organik jumlah berkisar 27,83-100,64 mg/l, konsentrasi nitrat berkisar antara 4,12-11,8 mg/l, dan klorofil-a pada empat stasiun berkisar 0,01- 6,31 mg/m3. Muara Sungai Cipasauran termasuk dalam kategori perairan yang subur (Eutrofik). Analisis regresi berganda memperlihatkan bakteri heterotrof signifikan pada bahan organik total (0,02< p<0,05). Adapun, ekstrak klorofil-a yang dihasilkan dari fitoplankton lebih tergantung kepada kadar nitrat (0,03<p< 0,05) dibandingkan terhadap kadar bahan organik total (0,11>p>0,05), sehingga unsur hara yang lebih banyak dibutuhkan adalah nitrat. Namun tingginya nitrat dapat memicu terjadinya eutrofikasi.  Kata Kunci : Bakteri Heterotrof; Bahan Organik Total; Nitrat; Klorofil-A; Muara Sungai Cipasauran ABSTRACT Cipasauran estuarine ecosystems utilized by local communities for household activities, such as bathing, washing clothes and fishing activities. These activities led to an influx of wastewater into waterways of the river. Downstream Cipasauran Estuary, ends at Anyer Beach. Fishing activities around Anyer Beach indicates the relatively good water quality. The purpose of this study is to determine the distribution of heterotrophic bacteria, total organic material, nitrate and chlorophyll-a, as well as to study the relationship between those variables. The material used in this study is water sampled from 4 location, at the estuary of Cipasauran down to Anyer Beach. The study used purposive sampling technique. Sampling was conducted at intervals of two weeks, each with two replication. The results showed that number heterotrophic bacteria in four stations ranged between 250-2500 cfu/ml, where as total organic materials ranged from 27.83 to 100,64 mg/l, nitrates ranged from 4.12 to 11.8 mg/l, and  chlorophyll-a at four stations ranged from 0.01 to 6.31 mg/m3. Cipasauran estuarine included in the fertile waters (Eutrofik). Regression analysis showed a significant increase in heterotrophic bacterial organic matter total (0.02<p<0.05). So, extract the chlorophyll-a resulting from more phytoplankton depend on nitrate levels (0.03<p<0.05) compared against the total organic material levels (0.11>p>0.05), so the more nutrient elements needed is nitrate. But high nitrate can trigger the onset of eutrophication.                Keywords: Heterotrophic Bacteria, Total Organic Material, Nitrate, Chlorophyll-a Cipasauran Estuary

Research into water quality status of accumulated water in decommissioned pits is a grey area in Ghana and could be of significant benefit in the effectiveness of remediation of pits after mining. Water sampled from four decommissioned pits in Amansie West District were analysed for their water quality status. Seasonal variations of physico-chemical parameters for determining water quality were reported as well as their average values. In general, the ion concentrations varied from season to season but were within World Health Organization (WHO) maximum permissible limits (MPL) with the exception of boron. Similar observation was made for heavy metals/trace elements analysed, with the exception of As and Fe. Seasonal and average concentrations of As were higher than the WHO MPL. Similarly, the mid-season concentration of Fe recorded from a water sample collected from one pit was higher than WHO limits. Turbidity levels were significantly higher in two pits. The studies revealed that some parameters for water quality determination were above WHO acceptable limits for potable water, an indication that the effect of mining on water quality from water bodies investigated persisted after mine closure. Hence remediation programmes should be broadened to include effective reclamation of mine water accumulated in pits during mine closure.

Balikpapan bay has an important and strategic role, such as a buffer for sustainability of the estuary function as the Balikpapan seaport. In Balikpapan esuary watershed there are large and small rivers, including Somber River. Settlements and industries around the river banks have caused a decrease of river water quality, especially activities that place pollutant loads (waste) on the river bodies. This research is focused on physical and chemical parameters, including Total Dissolved Solid (TDS), temperature, pH, and DO (Dissolved Oxygen).Water quality research was conducted by dividing the river into 7 measurment points. The distribution of measurement points was based on water quality considerations that represent upstream, middle, and downstream water quality, as well as considering easy access. Water samples at each mesurment point ware collected at three different depths (vertically). Concentrations of several parameters that have been obtained were then analyzed using the Pollution Index method (Pollution Index) which is used to determine relative pollutant levels to the allowed water quality parameters. The testing procedure by pollution index refers to procedure poured in the Decree of the State Minister for the Environment No. 115 in 2003 concerning of Determining Guidelines of Water Quality Status. Based on the field measurments, an average value for temperatures obtained ranging from 30.0 - 32.1 ° C, TDS values ​​4270 mg / L - 10000 mg / L, DO ranges between 1.8 mg / L - 3.1 mg / L, and pH values ​​between 6.6 - 7.1. From the calculation and data analisys of physical and chemical parameters, the research can be concluded that the location of measurement point 1 shows water quality status being lightly polluted, while point 2,3,4,5,6, and 7 shows water quality status being moderately polluted. Keywords: Water quality, estuary, Somber river, pollution index
