Coastal areas play a crucial role in maintaining the ecological balance of ecosystems and developing the social and economic wellbeing of the countries bordering it. However, the pressure on both terrestrial and marine resources, the use of oceans as a wastes deposit, the growth of population and the increasing of urbanization and human activities in coastal areas are all causes for marine and coastal degradation. The present situation constitutes a significant danger in many places. As an example, the pollution of the coastal waters in the Mediterranean has increased in recent years. Industrialization, tourism and ports activities along the coastline of the Mediterranean are the main sources of many pollutants that have effects on human’s health and environment. So that, it is very important to examine seawater quality in order to protect the marine and coastal areas from degradation. Hence, comes the need to consider a physicochemical and bacteriological study to evaluate the quality of Tangier coastal seawater using the Water Quality Index (WQI). A campaign of 25 sampling points was conducted and the results of the WQI calculation have highlighted the Tangier water was between medium and bad.

In seawater aquariums, seawater quality plays a very important role for the survival of the biota in it. There are measurement parameters that determine the quality of the seawater fit to be inhabited by seawater ornamental fish such as clown fish. Measurement parameters are such as temperature, salinity, dissolved oxygen content (DO), pH, ammonia, nitrite, and nitrate. Current technological developments make it possible to create a system that automatically conducts seawater drainage in a seawater aquarium so that the quality of the seawater remains in accordance with its measurement parameters and is fit for habitation by seawater ornamental fish such as clown fish. In this study the measurement parameters that become the reference are the temperature, pH (acidity) values obtained from the temperature sensor and the pH sensor. For normal temperatures, if the temperature is in the range of 24°C to 28°C, while for the ideal temperature is in the range of 25-27°C. For an appropriate pH in a saltwater aquarium is 7.5-8.5 with an ideal pH of 8.2. From the results of measurements made by these sensors, the value will be processed using the fuzzy logic method, then the condition of sea water quality in the aquarium can be seen from the smartphone, and when the measurement results show an inappropriate value, the system will automatically drain the water

Through the collection and analysis of COD, dissolved inorganic nitrogen (DIN) and active phosphate monitoring data in Tianjin Hangu Agricultural and fishery area from 2010 to 2019, this paper analyzed and studied the structure of nutrients and the state of eutrophication. The results show that in recent ten years, the water quality of Tianjin Hangu Agricultural and Fishery Area has basically met the water quality requirements of functional area, the regional nitrogen pollution has been suppressed, and the eutrophication index of sea area has shown a decreasing trend year by year, but the nitrogen and phosphorus nutrient structure is still in the state of “phosphorus restriction”. Pollution control of sea areas and conservation of aquatic germplasm resources are still urgent.

As the fast development of social economics, pollution accidents become more and more frequent. Yangtze estuary wetland is an important nature reserve. Evaluation of water quality becomes important in this area. However, evaluating water quality needs to concern many criteria such as chemical oxygen demand and content of harmful elements. Simply implement of criteria can cause bad results. This paper use Wavelet neural network to evaluate seawater quality of Chinese sturgeon reserve of the Yangtze estuary wetland in Spawning season successfully and calculate the quantities of floating animals and plants. The analysis also set up good mechanism of seawater quality evaluation.

ABSTRAK: Perairan Laut Kendal terhubung dengan Sungai Buntu, Sungai Kendal, dan Sungai Blorong yang membawa limbah dari kegiatan di darat seperti Mandi Cuci Kakus (MCK), peternakan, tambak, pertanian, dan kegiatan kapal dan Tempat Pelelangan Ikan (TPI). Hal ini akan mempengaruhi kualitas bakteriologis perairan laut Kecamatan Kendal. Penelitian ini dilakukan untuk menganalisa kualitas bakteriologis air dan sedimen perairan laut Kecamatan Kendal berbasis jumlah total bakteri dan Coliform. Sampel air laut dan sedimen diambil pada bulan Oktober Tahun 2019. Analisa bakteriologis dilakukan di Laboratorium Balai Pengujian Mutu Hasil Perikanan Semarang menggunakan metode berdasarkan ISO 6222: 1999 dan SNI 01-2332.3 – 2015, SNI ISO 9308 –1: 2010 dan SNI 01-2332.1 – 2006. Hasil penelitian menunjukkan jumlah total bakteri pada sampel air laut di stasiun 1 berkisar antara 190 Cfu - 240 Cfu, di stasiun 2 antara 340 Cfu - 380 Cfu. Jumlah total Coliform pada sampel air laut di stasiun 1 dan 2 adalah 1 Cfu/ 100 ml. Jumlah total bakteri pada sampel sedimen di stasiun 1 dan 2 yaitu antara 19.000 Cfu - 90.000 Cfu dan jumlah total coliform di kedua stasiun tersebut sebesar 3,6 MPN/g Coliform. Nilai total Coliform ini berada dibawah baku mutu air laut untuk biota laut, yang maksimum adalah 1.000 dengan toleransi <10%. Sedangkan untuk jumlah total bakteri tidak diatur dalam baku mutu air laut. Tetapi secara umum jumlah total bakteri di air laut terdapat 106 sel/ ml. Sehingga nilai hasil analisis total bakteri menunjukkan kualitas air laut yang masih baik. ABSTRACT: Kendal sea waters are connected to the Buntu River, Kendal River, and the Blorong River which carry waste from human activities such as domestic waste, fishery, agriculture, ship activities, and fish auction activities. These activities can influence the bacteriological quality of the waters of Kendal District. This research was conducted to analyze the bacteriological quality of seawater and sediments from Kendal Seawaters based on the total number of bacteria and Coliform. Seawater and sediment samples were taken on October 2019. Bacteriological analysis was conducted at the Semarang Fisheries Product Quality Testing Laboratory (BPMHP) using methods based on ISO 6222: 1999 and SNI 01-2332.3 - 2015, SNI ISO 9308-1: 2010 and SNI 01-2332.1 - 2006. The results showed the total number of bacteria in sea water samples at station 1 ranged from 190 Cfu - 240 Cfu, at station 2 between 340 Cfu-380 Cfu. The total amount of Coliform in seawater samples at station 1 and 2 are 1 Cfu / 100 ml. The total number of bacteria in sediment samples at station 1 and 2 are between 19,000 Cfu - 90,000 Cfu and the total number of coliforms at both stations are 3.6 MPN / g Coliform. The total value of this coliform is below the sea water quality standard for marine life, the maximum is 1,000 with a tolerance of <10%. Where as the total number of bacteria is not regulated in the seawater quality standard. But in general the total number of bacteria in seawater is 106 cells / ml. So the value of the total bacterial analysis shows that the quality of sea water is still good.
