Analysis of Various Types of Water Samples Using Different Quantitative Methodologies for Standardization Purposes in the Environmental-Chemistry and Microbiology Laboratory of Surabaya Institute of Standardization and Industrial Services

Abstract

Water is a vital part of the ecosystem. Not only is it significant for human survival and is essential for human health, it is also the main constituent of the earth’s hydrosphere and a crucial element which allows chemical reactions to take place. On the other hand, water is also highly affected by man made pollutants. Illegal and unmonitored waste dumping to water bodies contributes to umbrella issues that affect the human population and the environment. Understanding this, water monitoring has been made a requirement to maintain water quality and to determine possible bioremediation processes in case of contamination in Indonesia. BSPJI is a governmental institution that focuses on the standardization and the certification of, amongst other samples, different kinds of water in Indonesia. The institution is responsible to control and monitor the quality of the samples through various quantitative methodology analyses. The water in question includes drinking water, wastewater, and water obtained from environmental water bodies. This report aims to deliver the results of the tests done for said standardization and certification processes during the internship period. Amongst the many parameters done in the chemistry laboratory of BSPJI, the results of 6 parameters from the environmental-chemistry laboratory and 3 parameters from the microbiology laboratory were taken into account for this report. From the results obtained, most of the samples tested in the institution are within the safe range of SNI’s threshold, with only some exceptions such as the wastewater from slaughterhouses and drinking water from a few new companies whose product is not yet certified for nation-wide consumption.
