Seawater Quality

Faktor penting dalam usaha budidaya tambak adalah kualitas air laut yang sesuai dengan kebutuhan hewan budidaya. Media ini harus optimal semua parameternya. Pengukuran parameter fisik kualitas air laut dilakukan untuk menganalisis kesesuaian kondisi fisika air laut sebagai media budidaya sesuai daya dukung lingkungan perairan untuk usaha tambak. Sampel berupa air laut diambil dari 10 titik di sepanjang pantai Kabupaten Jepara dengan pengulangan masing-masing 3 kali. Analisa parameter fisika air laut yang diukur secara insitu adalah suhu, salinitas, dan kecerahan. Sedangkan total padatan tersuspensi dengan analisa sesuai prosedur pengukuran kandungan total zat padat tersuspensi berdasarkan SNI 06-6989.3-2004. Analisis daya dukung lingkungan dilakukan pada tiap titik dengan memberikan pembobotan terhadap parameter lingkungan perairan. Selanjutnya dikategorikan dalam sistem kelas, yaitu kelas S1 adalah tingkat sangat sesuai, kelas S2 adalah tingkat sesuai dan kelas S3 adalah tingkat tidak sesuai. Analisa menggunakan metode SIG untuk mendapatkan peta kesesuaian parameter kualitas air laut. Pengukuran parameter kualitas air di perairan Kabupaten Jepara mendapatkan data suhu sebesar 27,8-28,6oC, salinitas sebesar 35,0- 37,3 ppt kecerahan sebesar 70-120 cm dan Total Suspended Solid (TSS) sebesar 48,60-64,40 mg/l. Sepanjang perairan pantai Kabupaten Jepara tidak ada yang masuk dalam kelas S1. Lokasi perairan yang masuk dalam kelas S2 perairan Kecamatan Kedung, Kecamatan Tahunan, Kecamatan Keling dan Kecamatan Donorojo. Sedangkan kelas S3 berada pada perairan Kecamatan Jepara, Kecamatan Mlonggo, Kecamatan Bangsri dan Kecamatan Kembang.ANALYSIS OF SEA WATER PHYSICS PARAMETER DISTRIBUTION AS AN AQUACULTURE SUPPORT IN JEPARA REGENCY, CENTRAL JAVA. An important factor in pond aquaculture is the quality of sea water in accordance with the needs of cultivan aquaculture. This media must optimize all parameters. Measurement of physical parameters of seawater quality is carried out to analyze the suitability of the physical conditions of seawater as a culture medium in accordance with the carrying capacity of the aquatic environment for the pond business. Samples in the form of sea water were taken from 10 points along the coast of Jepara Regency with each repetition of 3 times. Analysis of seawater physics parameters measured in situ are temperature, salinity, and brightness. While the total suspended solids are analyzed according to the procedure for measuring the total content of suspended solids based on SNI 06-6989.3-2004. Environmental carrying capacity analysis is carried out at each point by giving a weighting to the parameters of the aquatic environment. Furthermore, it is categorized in the class system, namely the S1 class is a very appropriate level, the S2 class is the appropriate level and the S3 class is the inappropriate level. The analysis uses GIS method to get a map of the suitability of seawater quality parameters. Water quality parameter measurements in Jepara Regency waters get temperature data of 27.8-28.6oC, salinity of 35.0-37.3 ppt brightness of 70-120 cm and Total Suspended Solid (TSS) of 48.60-64, 40 mg/l. Along the coast of Jepara Regency, no one is included in the S1 class. The location of waters included in the S2 class of waters of Kedung Subdistrict, Tahunan Subdistrict, Keling Subdistrict and Donorojo Subdistrict. While the S3 class is in the waters of Jepara District, Mlonggo District, Bangsri District and Kembang District.

An attempt has been made to study the Physico-chemical condition of water of Yamuna River at Gokul Barrage, Mathura, (UP). The time period of study was July 2015 to June 2016. Three water samples were selected from different sites in each month for study. The parameters studied were Temperature, Turbidity, pH, DO, BOD, COD, Total Dissolved Solids and Suspended Solids. Almost all the parameters were found above the tolerance limit.

Reasonable Prediction

Recently, the Asian rivers have faced the strong reduction of riverine total suspended solids (TSS) flux due to numerous dam/reservoir impoundment. The Red river system is a typical example of the Southeast Asian rivers that has been strongly impacted by reservoir impoundment in both China and Vietnam, especially in the recent period. It is known that the reduction in total suspended solids may lead to the decrease of some associated elements, including nutrients (N, P, Si) which may affect coastal ecosystems. In this paper, we establish the empirical relationship between total suspended solids and total phosphorus concentrations in water environment of the Red river in its downstream section from Hanoi city to the Ba Lat estuary based on the sampling campaigns conducted in the dry and wet seasons in 2017, 2018 and 2019. The results show a clear relationship with significant coefficient between total suspended solids and total phosphorus in the downstream Red river. It is expressed by a simple equation y = 0.0226x0.3867 where x and y stand for total suspended solids and total phosphorus concentrations (mg/l) respectively with the r2 value of 0.757. This equation enables a reasonable prediction of total phosphorus concentrations of the downstream Red river when the observed data of total suspended solids concentrations are available. Thus, this work opens up the way for further studies on the calculation of the total phosphorus over longer timescales using daily available total suspended solids values.

Research was held in the estuary of the river Bach Dang (Dongbay community, Rakhtay district, Hai Phong, Vietnam) in June, 2012 - May, 2013. Concentration of lead was studied in water, suspended solids and bottom sediment. Clam beach (natural breeding environment of Meretrix lyrata ) was inspected regularly, every month. Water samples were taken 6 times from the bottom layer 10 cm down the bottom, once per 3 hours in each of 12 investigated zones. Bottom sediment samples were taken at the depth 2 cm. The findings show that lead accumulates mainly in suspended solids (23.3 mg/kg) and in bottom sediment (14.31 mg/kg), in water it is in small quantities (0.003 mg/kg). Analysis of bottom sediment samples taken in different places showed that they have even leadcontent, lead is distributed uniformly, localization of contaminations is not found. The results obtained can be assumed as the basis for investigating lead accumulation and its excretion by clam Meretrix lyrata organisms in the natural habitat.
