Abstract

Air minum merupakan air yang dikonsumsi langsung oleh  manusia melalui proses pengolahan atau tahapan proses pengolahan yang memenuhi syarat kesehatan. Pada saat ini air menjadi masalah yang perlu mendapat perhatian yang seksama. Pemenuhan kebutuhan air minum sangat tergantung pada faktor cakupan layanan air minum dan kondisi sanitasi pada masyarakat, baik pedesaan atau perkotaan. Penelitian ini bertujuan untuk mengetahui proses pengujian mikrobiologi air bersih dengan metode membran filter dan mengidentifikasi koloni bakteri E. coli dan coliform pada media CCA (chromocult coliform agar). Hasil penelitian yang diuji terdapat 2 sampel positif coliform yaitu sampel 0056/DAM/24 dengan jumlah 5/100 ml dan 0089/DAM/24 dengan jumlah 33/100 ml. Pada kedua sampel positif menunjukkan adanya bintik berwarna ungu pada kertas membran. Sampel air minum ini tidak memenuhi persyaratan mikrobiologi air minum pada Peraturan Menteri Kesehatan Republik Indonesia Nomor 492 Tahun 2010. Dalam persyaratan mikrobiologi, air minum yang memenuhi syarat kesehatan harus mempunyai total coliform yang berjumlah 0/100 ml air.

Abstract

Water is a very basic need for human life on earth. At this time, water is a problem that needs careful attention. Drinking water is water that is consumed directly by humans through a processing process or processing stages that meet health requirements. The busier human activities are, the more people tend to choose a more practical way with relatively low costs in meeting drinking water needs. The fulfillment of drinking water needs is highly dependent on the coverage of drinking water services and sanitation conditions in the community. This study aims to determine the level of contamination of Escherichia coli and coliform bacteria in refill drinking water and the feasibility of refill drinking water depots in Trucuk District, Bojonegoro Regency. The method used in this study is descriptive with a quantitative approach. The results of the study from 4 samples, namely AB, DAM 1, DAM 2, and DAM 3. 3 samples including AB, DAM 1, and DAM 3 were positive for containing Escherichia coli and coliform bacteria. Refill drinking water samples and raw water do not meet the requirements in accordance with the quality standards in the Regulation of the Minister of Health of the Republic of Indonesia No. 492 of 2010 "Concerning Drinking Water Quality Requirements" where the standard for microbiological parameter quality is 0 CFU / 100 ml.

Abstract

The Bojonegoro University Campus area has a high level of vehicle traffic every hour, which makes it one of the locations where air pollution spreads. Bojonegoro University always has vehicle activities such as motorbikes and employee and student cars. This allows for increased exposure to CO2 ambient air pollutants around campus. The number of vehicles and meteorological conditions such as air humidity, temperature, and wind speed can influence air quality. The quality of the outside air is influenced by the large number of motorized vehicle activities and meteorology, which causes the spread of air pollution at Bojonegoro University. Air quality that exceeds quality standards impacts health, such as respiratory problems. The research method used is a quantitative descriptive approach. Based on the measurement results, the CO2 concentration is included in the polluted air category, namely in the range 403 - 514 ppm, while the quality standard set by WHO is 350-700 ppm. The influence between CO2 concentration and the number of motorized vehicles has a positive correlation value with a coefficient of 0.825. The impact of CO2 concentration on meteorological conditions includes temperature, air humidity, and wind speed. The correlation coefficient values for temperature, humidity, and wind speed are 0.825, -0.820, and -0.882. Therefore, the number of vehicles and meteorological conditions strongly correlate with CO2 concentrations in the ambient air.
