Kualitas air di suatu wilayah yang merupakan salah satu indikator lingkungan dapat dievaluasi menggunakan parameter fisika, kimia, dan biologi. Indeks Kualitas Air Indonesia (IKA-INA) dapat digunakan untuk menilai kondisi kualitas air secara menyeluruh pada lokasi dan waktu tertentu. IKA-INA dihitung dengan menggunakan sepuluh (10) parameter yaitu pH, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), NO3, NH3, Total Phosphate (TP) dan fecal coliform. IKA-INA tersebut merupakan indeks kualitas air yang dapat memberikan informasi secara sederhana. Dalam pemanfaatannya, tidak semua data parameter dalam IKA-INA tersebut dapat terpenuhi karena adanya data tidak valid atau data yang hilang. Kajian ini bertujuan untuk memberi alternatif rumusan IKA-INA dengan parameter yang tidak lengkap atau jika tidak semua data dalam parameters tersebut tersedia. Metode yang digunakan dalam menyusun rumusan adalah dengan melakukan koreksi faktor bobot parameter IKA-INA terhadap parameter yang hilang dan nilai Q (nilai sub-indeks). Setelah itu dilakukan uji coba pada nilai baku mutu air dalam Peraturan Pemerintah No. 22/2021 Lampiran VI serta pada data kualitas air sungai yang mewakili kualitas baik dan buruk. Hasil uji coba menunjukkan bahwa bobot parameter terkoreksi dapat digunakan untuk penanganan parameter yang hilang dalam penilaian kualitas air dengan metode IKA-INA. Hasil IKA-INA dengan parameter hilang yang menggunakan bobot terkoreksi dan hasil IKA-INA dengan parameter lengkap mayoritas memberikan status IKA yang tidak berbeda, kecuali untuk parameter fecal coli dan parameter yang mempunyai kadar jauh berbeda terhadap kondisi air secara keseluruhan.

The study was carried out in a shallow phreatic aquifer in the piedmont zone between the Atlas Mountains and Tadla plain in Morocco. This study is carried out using physicochemical analyses with statistical analysis (CA and PCA) to show variability of groundwater hydrochemical parameters beneath Beni Mellal city in order to know spatial variability of water quality under urban activities. Total dissolved solid shows large variation from 355 mg/L to 918 mg/L with high values recorded, as electric conductivity, in the city center. High sulfate content is intercepted also in the old city center with values exceeding the threshold in the Moroccan guideline. Sulfate ions are often suspected of having an anthropogenic origin. All water samples show a dominance of Ca against Mg (Ca/Mg: 1.08–6.25) and HCO3 against SO4 (HCO3/SO4: 0.29–6.92). For most of the trace elements, the measured concentrations were far below the standard values except Al and Fe in some samples which exceed all guideline values. PCA of all dataset highlights eight factors with eigenvalues higher than 1 that explained about 80.34% of the total variance. The first two components PC1 and PC2 explained about 41.14% of the total cumulative variance and were responsible for 24.25% and 16.89% of the variance for each one, respectively. The component PC1 is mostly correlated with electric conductivity, TDS, and chloride. The component PC2 was highly correlated with Ca, Cr, and Zn. The dendrogram at a linkage distance of about 10.5 leads to dividing the diagram into three clusters of water samples, C1, C2, and C3. Cluster C1 shows a medium content of EC, HCO3, and NO3 and low content of TDS, Ca, Mg, Na, K, SO4, and Ba compared with C2 and C3. C1 samples show the lowest ion content, resulting probably from the minimal time of residence within the aquifer with low rock interactions. Cluster C2 regroups samples with high content of Ca, Mg, K, SO4, Al, and Cr, medium content of TDS and Na, and low content of EC, HCO3, NO3, and Cl. Samples in cluster C3 have more content of heavy metal (Cd, Fe, Mn, and Ni), CE, TDS, Ca, Mg, Na, HCO3, NO3, and Cl, with low content of Cr and Al and medium values of K and SO4. We recommended the monitoring and follow-up of the water quality under the city and the repair of pipes especially in the downtown area to limit unwanted infiltration. Spatial autocorrelation used with variograms and Moran'I leads to conclude that groundwater parameters varied differently according to the direction, which means that the semivariance depended on direction and distance between samples.

Penelitian mengenai parameter fisika, kimia, dan biologi penciri habitat ikan belida (Chitala lopis) dilakukan tahun 2005 - 2006 di perairan umum daratan di Sumatera, Kalimantan, dan Jawa. Tujuan nya adalah untuk mendapatkan informasi parameter lingkungan yang menjadi karakteristik habitat ikan belida dari berbagai badan air di Jawa, Sumatera, dan Kalimantan. Metode survei dan kegiatan laboratorium digunakan dalam penelitian ini. Parameter lingkungan yang diamati meliputi suhu udara, suhu air, Total Dissolved Solid (TDS), Daya Hantar Listrik (DHL), klorofil-a, kecepatan arus, Biological Oxygen Demand (BOD), oksigen terlarut, pH, alkalinitas, CO2 bebas, kedalaman air, dan kecerahan pada 116 lokasi pengambilan yang ditentukan secara sengaja di Sungai Tulang Bawang (Provinsi Lampung), Sungai Kampar, Sungai Siak (Provinsi Riau), Sungai Musi (Provinsi Sumatera Selatan), Sungai Citarum (Provinsi Jawa Barat), Sungai Kapuas (Provinsi Kalimantan Barat), dan Waduk Riam Kanan (Provinsi Kalimantan Selatan). Analisis data menggunakan pendekatan analisis multivariabel regresi berganda Metode Backward yang didasarkan pada Analisis Komponen Utama (Principal Component Analysis) dan pembeda (Discriminant Analysis), serta korespondensi analisis (correspondency analysis). Hasil penelitian menunjukkan habitat ikan belida dapat dibedakan menjadi tiga tipe, yaitu tipe yang menyerupai sungai utama, waduk, dan anak sungai. Pembeda utama sekaligus parameter lingkungan utama adalah parameter TDS yang paling besar, dan selanjutnya parameterparameter DHL, suhu udara, klorofil-a, kecepatan arus, BOD, Oksigen terlarut, pH, alkalinitas, dan CO2 bebas menyumbang yang paling sedikit. Kehadiran plankton genus Ulothrix dan Mytilina secara tidak langsung teridentifikasi sebagai penciri habitat spesifik ikan belida. Research on physical, chemical, and biological parameters indicating specific habitat of clown knife fish (Chitala lopis) was carried out at 2005 - 2006 in inlands waters of Sumatera, Borneo, and Java. This study purposed to obtain information of environmental parameters indicating habitat characteristic of the knife fish in various inland waters bodies in Sumatera, Borneo, and Java. Survey method and laboratory activities were employed in this research. Environmental parameters observed were air temperature, water temperature, Total Dissolved Solid (TDS), conductivity, water velocity, Biological Oxygen Demand (BOD), dissolved oxygen, pH, alkalinity, free C02, water depth, and water transparancy taken on 116 sampling stations distributing in Tulang Bawang River (Lampung Province), Kampar and Siak River (Riau Province), Musi River (South Sumatera Province), Kapuas River (West Kalimantan Province), Riam Kanan Reservoar (South Kalimantan Province), and Citarum River (West Java Province). Data analysis used multivariate approach of multiple regression of Backward Method such as Principal Component Analysis, Discriminant Analysis, and Corre spondency Analysis. The results showed that the clown knife fish habitats could be divided by three types of specific habitat, namely water bodies similar with main rivers, reservoir, and tributaries. Parameter of TDS indicated the primary differentization as well as habitat characteristics of the clown knife fish.Whilst the parameters of conductivity, air temperature, chlorophyill-a, water current, BOD, dissolved oxygen, pH, alcalinity, and free CO2 contributed less significance. The existence of plankton from genus Ulothrix and Mytilina was identified indirectly as the specific habitat of the clown knife fish.

ABSTRACT Rio da Serra watershed presents well preserved fragments of rain forest at the headwaters and small farms at middle and final stretches. These features allowed the study of fluvial hydrochemistry, under quasi pristine conditions. Sampling stations were established in order to represent the basin, and visited during dry, intermediate and wet periods. Obtained results are: temperature (22.1 – 28.6 °C); electric conductivity (34 – 52 µS/cm); dissolved oxygen (35 – 110%); pH (3.8 – 7.7); total suspended solids (1.1 – 20 mg/L); chlorophyll (1.0 – 9.2 µg/L); total N (74 – 580 µmol/L); particulate N (60 – 550 µmol/L); N-NO3 (0.1 – 9.3 µmol/L); dissolved organic N (4 -70 µmol/L); total phosphorous (5.3 – 47 µmol/L); particulate P (4.4 – 59 µmol/L); P-PO4 (0.1 – 0.7 µmol/L); dissolved organic P (0.01 – 2.0 µmol/L); silicate (30 -90 µmol/L); fecal coliforms (80 – 700 CFU/100mL). In seasonal terms dissolved oxygen, electric conductivity, nitrate and silicate concentrations were higher during the dry, whereas TSS was higher during the wet period. Seasonal differences of dissolved oxygen, temperature, pH and nitrate were also detected near wetlands areas. Along the basin results showed a distinction between headwaters and other sections, revealing a control of fluvial hydrochemistry by the preserved area, mostly for the dissolved organic N and P species and phosphate.

Abstract The recent climate condition and pollution problem related to surface water have led to water scarcity in Malaysia. Huge amount of groundwater has been identified as viable source for drinking water. This paper was aimed to investigate groundwater’s quality at specific location and metakaolin’s potential in the groundwater treatment in the removal of manganese. Groundwater purging was determined to be sufficient at 120 minutes where all three parameters (pH, dissolved oxygen and conductivity) were stabilized. The groundwater studied is classified as both anoxic and reductive due the low dissolved oxygen value. It also can be categorized as brackish due to high value of conductivity and total dissolved solid. Manganese content in groundwater was determined as higher than of that permissible limit for raw water and drinking water which makes it unsuitable for them not suitable for consumption and cleaning purpose. Average manganese concentration in samples was 444.0 ppb where the concentrations of manganese ranged from 229.4 ppb to 760.3 ppb. Manganese developed is not that a strong positive correlation against iron concentration, total dissolved solids and conductivity; whereas has a moderate negative correlation against dissolved oxygen. The capability adsorption of manganese by metakaolin was assessed via batch method which indicated optimum dosage and contact time was 14g that removed average 30.2% and contact time optimum at 120 minutes which removed 33.2% manganese from the sample.

High community activity on the border of the Bah Biak River causes pollution in the waters of the river. The increase in the number of settlements and industries in Pematangsiantar city certainly has an impact on the quality of its waters. The purpose of this study is to find out the water quality of the Bah Biak River in Pematangsiantar City covering the physical and chemical parameters of the waters. This research was conducted in 2021 in Bah Biak River Pematangsiantar city. Water sampling in the Bah Biak River is carried out with three repetitions, namely in March, June and August taking into account the representation of the seasons. Water sampling is carried out in situ for parameters of brightness, pH, total dissolved solid (TDS), electrical delivery, temperature and dissolved oxygen (DO), ammonia, while for laboratory scale measurements are carried out for biologycal oxygen demand (BOD) and chemical oxygen demand (COD) parameters. The results of the measurement will be displayed in graphic form and descriptively discussed by referring to the specified quality standards. Based on the results of measurements of several water quality parameters in the Bah Biak River, it can be concluded that the majority of the parameters studied still meet the quality standards but there are parameters that have passed the quality standard threshold, namely BOD and ammonia parameters.   ABSTRAK Tingginya aktivitas masyarakat di sempadan Sungai Bah Biak menyebabkan pencemaran di perairan sungai tersebut.

The physicochemical parameters of the thirty water samples collected at the point of discharge of abattoir wastewater as site A (upstream), site B  (downstream) and site C (the irrigation space) of the seasonal River Tagangu were analyzed. The parameters tested include: pH, temperature, turbidity, conductivity, dissolved oxygen (DO), biological oxygen demand (BOD), nitrate, sulphate, phosphate and ammonium. All the parameters were tested following the standard procedures. The pH values obtained ranged from 6.5–7.9; suggestive of suitability of the water for bacterial growth. The temperature values ranged from 21.2–31.2oC; falling within the WHO standard. The turbidity of the water samples ranged from 520–627 NTU, which are exceedingly higher than WHO limit. The conductivity of the water samples ranged from 42.9–624.0 mS/cm; values were far higher than 400.0 mS/cm of WHO standard. The dissolved oxygen (DO) measured between 6.9-19.0 mg/l; which is also greater than WHO standard (6.0 mg/l). Biological oxygen demand (BOD) measured between 312–527.9 mg/l; greater than WHO threshold of 10.0 mg/l. The nitrate contents varied between 39.2–72.3 mg/l; greater than WHO standard (10 mg/l). The sulphate values varied between 45.6–93.9 mg/l; falling within the WHO threshold. However, values greater than 10 mg/l, suggests that the water has been polluted. The phosphate contents observed ranged from 0.435–0.849 mg/l across the three sites, values were higher than 0.3 mg/l of WHO standard. The ammonia contents of the water samples ranged from 27.7–948.5 mg/l; far greater than 0.5 mg/l of WHO standard. The physicochemical study across the three (3) sites shows the typical pollution of the river and rendered the quality of the water hazardous to humans, animals and aquatic lives that could be the users of the water.
