“…37 It is known that the concentration of chlorophylla is related to inorganic phosphate concentrations and the Pearson Correlation Index result positive correlation between phosphate and chlorophyll-a support it. 38 The value of Kelly index (KI) is less than 1 in all stations and the water is suitable for irrigation (Table S-I). With respect to the sodium adsorption rate (SAR), the value is between 0-10 in all stations and the results show that the water is excellent for irrigation (Table S…”

K?rklareli Reservoir locating in Meri?-Ergene River Basin is an important drinking/using a freshwater resource of K?rklareli Province. In order to ensure the sustainable use of this important reservoir, its current situation should be examined periodically and evaluated by multivariate analyses. For this reason, the water samples were taken between the dates April 2018 and February 2019 at monthly intervals from 3 different stations. The data of environmental and physicochemical variables (water temperature, dissolved oxygen, pH, salinity, conductivity, total dissolved solids, Chlorophyll-a, light permeability, fluoride, chloride, NO2-N, NO3-N, PO4, SO4, and essential/potentially toxic elements) measured and evaluated according to the classes in surface water quality control regulation of Turkey. The parameters exceeding first-class water quality values (chlorophyll-a, pH, NO2-N, chloride, selenium) were mapped in GIS using Spline integration approach. Also, Sodium Absorbtion Ratio, Kelly Index Values, and Magnesium Ratio, were calculated to evaluate the water quality for agricultural irrigation water standards. The water quality of the reservoir was evaluated by using multivariance analyses (Bray-Curtis Similarity Index, Correspondence Analyses, Pearson Correlation Index). As a result, it was emphasized that using GIS approach is a potential useful method of monitoring the sustainable water quality of K?rklareli reservoir which is determined to have an oligomesotrophic character.

“…Dampak positif terjadi karena produktivitas perairan menjadi tinggi, sedangkan dampak negatif akibat proses eutrofikasi yang menyebabkan algae jenis beracun berkembang dengan pesat dan menyebabkan oksigen perairan menjadi rendah. Hasil penelitian Maslukah et al (2019) tentang unsur phosphat terlarut di perairan Semarang mencapai 0,52 µM dan Jepara 0,36 µM. Beban masukan ion P yang cukup tinggi telah menyebabkan konsentrasi klorofil-a menjadi lebih tinggi dibanding dengan perairan Jepara.…”

Adsorpsi dan desorpsi merupakan proses penting yang mempengaruhi distribusi bahan kimia di lingkungan. Penelitian ini bertujuan untuk menentukan pola perubahan konsentrasi ion PO42- terhadap waktu melalui proses simulasi adsorpsi dan desorpsi sedimen perairan Semarang dan Jepara. Melalui proses desorpsi, dapat ditentukan kontribusi masukan ion PO42- oleh sedimen yang ditentukan dari jumlah ion PO42- yang terlepas pada awal sampai pada kondisi maksimum dari proses desorpsi. Penentuan kinetika adsoprsi ditentukan berdasarkan persamaan orde 1 dan 2 serta isoterm adsorpsinya berdasarkan model Langmuir dan Freundlich. Hasil penelitian menunjukkan bahwa proses desorpsi terjadi pada 1 jam pertama dan kontribusi ion PO42- yang dapat dilepaskan oleh sedimen perairan Semarang tiga kali lebih besar dibandingkan dengan sedimen perairan Jepara. Berdasarkan kinetika adsorpsi ion P oleh sedimen dari dua lokasi lebih tepat dijelaskan oleh model persamaan ordo 2 dan isoterm adsorpsinya berdasarkan model Langmuir. Model ini mengasumsikan bahwa kapasitas adsorpsi sebanding dengan jumlah situs aktif yang ditempati oleh ion PO42- dan adsorpsi terjadi dalam satu lapisan sedimen homogen. Sedimen Semarang memiliki kemampuan menyerap zat pencemar (ion P) lebih besar dibandingkan dengan sedimen Jepara dengan nilai kapasitas secara berurutan adalah 11,57 dan 11,2 µmol g-1.

“…Maslukah et al (2018) explained that chlorophyll a in Jepara waters had the strongest correlation to the N/P ratio, followed by P and finally N individually. The following study, Maslukah et al (2019), found a relationship of chlorophyll a to nutrient P following a logarithmic model with the formula [Chl-a] = 1.52 + 1.60 logs [P], with a correlation coefficient (r) of 0.74. A comprehensive model of this relationship that can be applied to waters with different characteristics would be very valuable to develop effective policies to control the water quality (Abell et al 2012).…”

“…This region has experienced very rapid development because it is the main center of economic growth in Central Java. Several studies related to the chlorophyll a concentration have been carried out by Siregar and Koropitan (2016), Subiyanto et al (2017) and Maslukah et al (2019). The concentration of the particulate P forms in waters is rarely measured.…”

The speciation of particulate inorganic phosphate (PIP) in waters is still rarely studied, unlike the dissolved inorganic phosphate (DIP) which is often used in the assessment of the water quality parameters and their effect on the presence of chlorophyll a. This research aimed at determinig the relationship between DIP and PIP and its effect on the concentration of chlorophyll-a. This research was conducted in the waters of Semarang and Jepara, in different seasons (Rainy and dry). Speciation from PIP was obtained through an extraction process using 1 M HCL and continued with phosphate analysis using the molybdenum blue method, as in the DIP analysis. The linear model was used to find an equation and determine the variables that affect chlorophyll a. Our results showed that the distribution patterns of DIP, PIP and Chlorophyll-a have different patterns in the two study areas and different seasons. The concentration of DIP is always high in the Semarang waters, and is followed by a high chlorophyll-a response. A different pattern was found in the Jepara waters, where the chlorophyll-a response is high in the east monsoon. The relationship of Chl-a to DIP was very significant in the west season in the waters of Semarang and the Jepara region in the east season (p <0.05). The relationship of chlorophyll a to DIP in the Semarang and Jepara waters produced an equation, Chl a = -56.565 + 76.672 (DIP) with a coefficient of determination R 2 = 0.478, at a significant level (p) = 0.004 and Chl a = -25.844 + 68.827 (DIP) with value of R 2 = 0.421 at a significance level of p = 0.007, respectively.
