Selection Of

Water is an important need for all living things, especially humans. Humans need water with quality that meets the physical, microbiological, chemical, and radiological requirements contained in the mandatory and additional parameters. The selection of these parameters is very important to meet the requirements of good water, namely tasteless, odorless, and colorless. Meanwhile, there are three parameters used for water identification, namely pH parameters, turbidity levels, and temperature parameters. From these problems, the authors examine the detection of water quality, especially water turbidity. The author tries to make a tool that can detect the level of turbidity of water with a turbidity sensor as a detector of the level of turbidity in the water, Arduino Uno as a processor for the data results that have been detected, and a 16x2 LCD as a display of turbidity level measurement results in the form of turbidity values ​​and descriptions of the water being tested. The measurement range that can be detected by this tool is from 0 – 3000 NTU. The research method used is direct observation of the selected object, namely the author's home environment, and conducting library research related to the Arduino microcontroller. The purpose of this study was to determine and detect the level of water quality in the community. As one of the tools or alternatives for the community to find out or detect the level of water quality early.

The State special primary acceleration measurement standard for gravimetry (GET 190-2019), its composition, principle of operation and basic metrological characteristics are presented. This standard is on the upper level of reference for free-fall acceleration measurements. Its accuracy and reliability were improved as a result of optimisation of the adjustment procedures for measurement systems and its integration within the upgraded systems, units and modern hardware components. A special attention was given to adjusting the corrections applied to measurement results with respect to procedural, physical and technical limitations. The used investigation methods made it possibled to confirm the measurement range of GET 190-2019 and to determine the contributions of main sources of errors and the total value of these errors. The measurement characteristics and GET 90-2019 were confirmed by the results obtained from measurements of the absolute value of the free fall acceleration at the gravimetrical site “Lomonosov-1” and by their collation with the data of different dates obtained from measurements by high-precision foreign and domestic gravimeters. Topicality of such measurements ensues from the requirements to handle the applied problems that need data on parameters of the Earth gravitational field, to be adequately faced. Geophysics and navigation are the main fields of application for high-precision measurements in this field.

Arabic learning can take place at various ages of either children, adolescents or adults. Learning Arabic is something needed for especially Muslim because it is important in Muslim life. This paper will explain about the Arabic learning strategy for children. This is important to discuss because children need special strategies in learning for their ages. In collecting information, the writer uses library research method, which is done by comparing several literary sources, especially those that are the main source of discussion to discuss about the existing problems. Then, as the result, language learning is a help to determine how, and how well, learners learn a foreign language. There are many variations on learning strategy. Arabic learning strategies for children include playing, singing, telling stories, projects, demonstration, and conversation. By using the suitable and fun strategy, children can develop their potential well and effectively. The selection of learning strategies depends on children’s ages and characteristics.

The World

In the 21st century, the world had advanced through lots of innovations; its parallel impact in the form of pollutions, global warming and climatic change crisis are being raised. These crises create a gap in terms climatic changes, poor air quality, and unsafe drinking water for the population around the world. Among all pollutants, water pollution is a thrust area as it is a prominent parameter in the food chain of living things. There are huge numbers of diseases that are attributed due to polluted water. The water sources are mainly polluted due to untreated sewage and industry discharges. But mainly industrial wastewater discharge contributes to the accelerated pollution in the water bodies. The proposed design focuses on monitoring the water quality parameters like pH, TDS, TOC, and Chlorine content, conductivity etc., using wireless Sensor Nodes around open ponds and wells near tannery units. The data is transmitted to the cloud, and further information is given to the people through GSM. Repository of data is maintained in order to take it for further analysis. Results obtained from the model indicate the values of the above mentioned parameters.

Water is a natural resource that is needed for the life of human being, even for all the creatures. Therefore, these water resources must be protected so that humans and other living things can be utilized properly. The macrofauna community defines whether the water quality is good or not. The study of the effect of river water quality on the diversity of macrofauna in the Metro river flow of Lowokwaru Subdistrict, Malang City aims to determine the effect of river water quality and to compare the diversity of macrofauna in several Metro river locations in Lowokwaru District, Malang. The method used is quantitative descriptive by calculating the Shanon Winner diversity index. The results obtained for station I amounted to 1.95 classified as lightly polluted, at station II the results were 1,007 which were classified as moderately polluted, and at station III the results were 0.69 which were classified as heavily polluted. Key Words: water quality, macro fauna, Metro river ABSTRAK Air merupakan sumber daya alam yang diperlukan untuk kebutuhan hidup orang banyak, bahkan oleh semua makhluk hidup.

Vaname shrimp is one type of shrimp that the people of Indonesia widely cultivate. However, there are several problems in the failure of vaname shrimp production, including poor water quality during the maintenance period, especially in ponds. Based on the selection of inclusion and exclusion criteria and quality assessment, it was found that the use of technology in cultivation activities will help streamline time, energy, and human resources so that decision-making can be made faster. The technology used is limited to water quality monitoring, disease monitoring, and EMS. The methods used to create IoT-based technology are hardware devices, software tools, function tests, and user tests. The smaller the error value, the more accurate the data obtained.
