Abstract
Perkembangan pembangunan saat ini di Kota Surabaya harus diikuti oleh pemenuhan air minum. Cakupan pelayanan air minum kota Surabaya Tahun 2016 sebesar 95,51%. Target PDAM Surya Sembada dapat melayani 100% penduduk kota Surabaya di tahun 2018. Permasalahan air minum yang terjadi di Surabaya utamanya pada kualitas air. Tingginya kandungan bakteri Coliform dalam kualitas air PDAM salah satu masalah utamanya. Permasalahan ini terjadi karena banyak faktor terutama dengan parameter tekanan, kekeruhan dan sisa chlor. Penelitian ini mengkaji dinamika bakteri Coliform yang disebabkan oleh tekanan, kekeruhan, dan sisa Chlor dalam sistem distribusi. Penelitian ini bertujuan untuk menentukan hubungan tekanan, kekeruhan dan sisa chlor terhadap bakteri Coliform di zona 2 PDAM Surabaya.
Metode untuk menghubungkan ketiga parameter terhadap bakteri Coliform dengan menggunakan analisis korelasi program SPSS. Analisis ini mencari angka korelasi dan nilai signifikansi dari kedua variabel yang dihubungkan. Analisis korelasi yang digunakan yaitu korelasi sederhana (bivariat). Batasan nilai korelasi anatra 0,4-0,6, jika berada dibawah nilai tersebut dikatakan rendah dan jika diatas nilai tersebut dikatakan kuat. Hasil analisis korelasi sederhana dari tekanan, kekeruhan, dan sisa chlor terhadap bakteri Coliform yaitu 0,486, 0,264, dan 0,842. Hasil analisis korelasi sederhana untuk antar variabel yaitu korelasi tekanan dengan kekeruhan 0,699, tekanan dengan sisa chlor 0,74 dan kekeruhan dengan sisa chlor 0,349. Hal ini menunjukkan bahwa parameter tekanan dapat mempengaruhi sisa chlor yang berimbas pada kandungan bakteri coliform dalam sistem distribusi.
Hasil analisis korelasi menunjukkan bahwa parameter sisa chlor mempunyai nilai korelasi sangat kuat terhadap bakteri Coliform dibandingkan parameter tekanan dan kekeruhan. Sisa chlor adalah parameter yang paling berpengaruh dalam keberadaan bakteri coliform. Nilai bakteri coliform yang berfluktuatif diakibatkan sisa chlor yang dipengaruhi oleh jarak, dan umur pipa, selain dengan bakteri itu sendiri. Parameter tekanan juga dapat mempengaruhi kadar sisa chlor sehingga tekanan dan sisa chlor merupakan faktor kunci dalam dinamika bakteri coliform.
================================================================================ The current development in the city of Surabaya to be followed by the fulfillment of the drinking water. These developments should also be followed by the fulfillment of the drinking water. The scope of the service of drinking water the city of Surabaya 2016 of 95.51%. Target PDAM Surya Sembada can serve 100% of the population of the city of Surabaya in 2018. The problem of drinking water occurred in Surabaya on the main water quality. The high Coliform bacteria content in water quality PDAM one of the main problems. This problem occurs because many factors especially with parameters pressure, turbidity, and chlor residual. This study examines the dynamics of bacterial Coliform caused by pressure, turbidity, and Chlor residual in the distribution system. This research aims to determine the relationship of pressure, turbidity, and chlor residual against Coliform bacteria in zone 2 PDAM Surabaya
The methods used in this study to link the third parameter against the bacteria Coliform with an analysis of the correlation program SPSS. This analysis searched for the number and value of correlation significance of both variable money is connected. The analysis of correlation used i.e. simple correlation (bivariate). Limit value correlation Center 0.4-0.6 point, if it is under the value is said to be low and if above that value are said to be strong. Simple correlation analysis results from pressure, turbidity, and chlor residual against Coliform bacteria that is 0.486, 0.264, and 0.842. Simple correlation analysis results for between variabels, namely the correlation between pressure with turbidity 0.699, pressure with the chlorine residual 0.74 and turbidity with chlor residual 0.349. This indicates that the parameter pressure can also affect the chlorine residual promoted bacterial coliform content in the distribution system.
Correlation analysis of the results shows that the parameters Chlor residual has a value of correlation is very strong against the bacteria Coliform than the parameter pressure and turbidity. The chlor residual is the most influential parameters in the presence of coliform bacteria. The value of the coliform bacteria are unstable due to chlorine residualhas kinetics with distance, and the age of pipe, in addition with the bacteria itself. The parameter pressure can also affect the rate of the rest of the chlor so pressure and chlorine residualis a key factor in the dynamics of coliform bacteria.
