Penelitian ini bertujuan menganalisis kelayakan perairan berdasarkan parameter fisika dan kimia perairan danau Paniai untuk kegiatan budidaya ikan. Penelitian ini merupakan penelitian deskriptif kuantitatif dengan mengkaji kondisi kualitas air perairan danau Paniai, Papua. Pengambilan dan pengukuran sampel air pada setiap lokasi sampling dilakukan dengan metode composite sampling (gabungan tempat). Contoh air danau diambil pada permukaan dan pertengahan. Pengukuran dan pengumpulan data dilakukan sebanyak 2 kali dengan interval waktu antar pengukuran selama 1 bulan. Hasil penelitian didapatkan parameter fisika masih memenuhi syarat baku mutu, parameter kimia, dari delapan parameter yang diukur terdapat 3 parameter yang tidak memenuhi baku mutu yaitu, H2S, Nitrat dan Posfat. Hal ini menunjjukan bahwa tingginya buangan limbah dari sektor pertanian dan rumah tangga yang masuk ke dalam danau dan berpontesi terjadinya eutrofikasi dan peledakan pertumbuhan tanaman air. This study aims to analyze the feasibility of the waters based on the physical, chemical and biological parameters of the waters of Paniai lake for fish farming activities. This research is a quantitative descriptive study by examining the condition of the water quality of the waters of Lake Paniai, Papua. Water samples were taken and measured at each sampling location using the composite sampling method (combined places). Lake water samples were taken at the surface and in the middle. Measurement and data collection were carried out 2 times with an interval of 1 month between measurements. The results showed that the physical parameters still show the quality standard requirements, chemical parameters, from the eight parameters measured there were 3 parameters that did not show the quality standards, namely, H2S, Nitrate and Phosphate. This shows that the high discharge of waste from the agricultural and household sectors that enters the lake has the potential for eutrophication and explosive growth of aquatic plants.

Water as a natural resource is needed in life. Nowadays, the need for freshwater is increasing. Meanwhile, most people fulfill their daily water needs from well water. This study aims to determine the quality of well water in the IAIN Tulungagung campus area based on physical, chemical, and biological parameters. This type of research is a quantitative descriptive. A total of 12 points from 4 stations were chosen by random sampling. Laboratory test results were compared with PerMenKes RI No. 492/MENKES/PER/IV/2010 and PerMenKes RI No. 32 Tahun 2017. The results of the study show that (1) two sources of water do not qualify as clean water based on physical parameters because the turbidity value and total dissolved solids (TDS) exceeds the quality standard, (2) five sources of water do not qualify as water clean based on chemical parameters because the Fe content exceeds the quality standard and/or low dissolved oxygen (DO) concentration, and (3) four wells do not meet bacteriological tests for the amount of coli fecal bacteria and total coliform. Well water in the IAIN campus area has decreased water quality caused by domestic waste.

Abstract The aim of this study was to assess the bacteriological quality of water sources in the two rural areas of Uganda using the compartment bag test (CBT). In total, 200 water samples were collected from 69 different water sources and processed within 6 h of collection. Positive and negative controls were processed each day together with water samples. Physical parameters were measured in situ. Descriptive statistics were used to generate mean, minimum, maximum, standard deviations and percentages. The results indicated that 29% of the water sources met the National Standards and World Health Organization (WHO) Guidelines for drinking water. Sixty percent of the borehole, 44% of gravitational flow taps and 14% of roof rain water met the required standards. Of the open water sources, 75% of the rivers, 50% of open channels and 43% of unprotected dug wells plus 25% of protected springs and 9% of gravitational flow schemes had most probable number counts >100 Escherichia coli/100 mL of water. Most of the water sources in the study areas were not fit for human consumption without prior treatment. The CBT was found to be robust and easy to use in all field situations. The mean physical parameters of water sources were within the acceptable limits.

This paper presents an experimental platform allowing in situ measurement in an aqueous medium using an acoustic Love wave sensor. The aim of this platform, which includes the sensor, a test cell for electrical connections, a microfluidic chip, and a readout electronic circuit, is to realize a first estimation of water quality without transportation of water samples from the field to the laboratory as a medium-term objective. In the first step, to validate the ability of such a platform to operate in the field and in Amazonian water, an isolated and difficult-to-access location, namely, the floodplain Logo Do Curuaï in the Brazilian Amazon, was chosen. The ability of such a platform to be transported, installed on site, and used is discussed in terms of user friendliness and versatility. The response of the Love wave sensor to in situ water samples is estimated according to the physical parameters of Amazonian water. Finally, the very good quality of the acoustic response is established, potential further improvements are discussed, and the paper is concluded.

This study discusses the content of heavy metal Cd in sungai Barumun Labuhanbatu  Selatan. The research was conducted in December 2020 until January 2021 in the region of the waters of the River Barumun Labuhanbatu Selatan. The process of sampling using purposive sampling method. Data analysis was done descriptively by looking at the results of the measurements of some parameters of the waters and the test results of water samples in the laboratory by comparing the quality standard according to the Decision of the Minister of Environment No. 51 Year 2004. As for the test sediment samples in the laboratory compared with the raw quality of the concentration of heavy metals in the sediment IADC/CEDA 1997. The results of the heavy metal concentration of Cd in the surface water ranged 0,003-0,068 mg/l, the concentration of heavy metal cadmium in water depth of 5 meters has a range of 0.007-to 0.058 mg/l.

Spring is as one of the water resources potential that can not be ignored. Gunungkidul district has three physiographic units: Baturagung Hills, Wonosari Basin and Gunung Sewu Karst Hills. All of them affect the distribution of springs in the Gunungkidul Regency. On the other hand, physiography will affect the community adaptation to the environment. It will contribute to the springs conservation effort. The purposes of this research are:  1) to identify the characteristics of springs, 2) to analyze the community participation in conserving  the springs as basic information to develop spring conservation models. To identify the socio-economic characteristics and the springs characteristics in the research areas use a survey method. Unit sampling and analysis is done purposively based on three zones: Baturagung Hills, Wonosari Basin and Gunung Sewu Karst Hills. Socio-economic survey was done by sampling on the 90 respondents, divided into 3 zones through direct interviews using quetionare. Quantitative descriptive analysis was performed through statistical tests. The results show that the quality of spring water in all physiographic zones meet to the water quality standard, except those for colli bacteria. The discharge of karst springs in the hills of Gunung Sewu greater than the discharge of the two other zones. The springs distribution is more in Wonosari Basin and Karst Hills of Gunung Sewu than Baturagung Hills. The level of the community participation in springs conservation is mostly done in groups through user spring groups. Generally, socio-economic factors affect to the level of participation in prevention of springs damage.

Saguling reservoir in West Java Province is becoming increasingly polluted by heavy metals. The purpose of this study was to determine the level of four heavy metals such as Cd, Cr, Cu, and Pb concentration at Saguling Reservoir at ’2 sampling location. Water samples were collected during rainy and summer 2008-2017 to determine the spatial distribution seasonal and temporal variation of different heavy metal contents. Mean metals concentrations in summer seasons were Cd, Cr, Cu, and Pb higher than rainy season. Mean concentration of Cd, Cu, Cr, and Pb in water samples were accordance water quality standard in both season. Heavy metal pollution that occurs in the Saguling reservoir must be monitored because this reservoir is planned to be a source of raw water for Bandung City.
