Abstract
Pencemaran air khususnya pencemaran di sungai kini menjadi masalah serius yang harus ditangani. Salah satu anak sungai Lamongan yang dikenal dengan Kaliotik menunjukan tanda-tanda sedang tercemar. Bahan pencemar yang masuk ke dasar sungai terus menerus bertambah sehingga membuat kualitas air terus menurun. Bahan pencemar yang masuk berasal dari limbah domestik, pasar ikan dan pertanian. Perlu dilakukan upaya untuk melakukan rehabilitasi untuk memperbaiki kualitas air. Adapun tujuan dari penelitian ini ialah (i) menganalisis distribusi zona cemaran kualitas air; (ii) menganalisis isolat dan konsorsium bakteri yang mampu untuk mendegradasi senyawa LAS, amoniak dan fosfat; (iii) merekomendasikan aplikasi konsorsium mikroba dalam merehabilitasi sungai Kaliotik. Jenis penelitian yang digunakan dalam penelitian ini ialah kuantitatif deskriptif analisis dengan desain penelitian true experimental time series pre-test post test design. Analisis zona cemaran kualitas air dilakukan melalui index biotilik dan self purification. Analisis isolat dan konsorsium bakteri pendegradasi pencemar melaui screening dan identifikasi 16sRNA bakteri, serta analisis kemampuan isolat mikroba dalam mendegradasi senyawa pencemar dengan zona bening. Hasil dari penelitian ini yaitu (i) distribusi zona pencemaran kualitas air sungai Kaliotik menunjukan tercemar berat dengan nilai indek pencemar sebesar 2,74; (ii) isolat dan konsorsium bakteri yang memiliki kemampuan untuk mendegradasi LAS, amoniak dan fosfat pada sungai Kaliotik yaitu Pseudomonas aeruginosa, Nitrobacter vulgaris dan Bacilus cereus, Pseudomonas aeruginosa mampu mendegradasi LAS sebesar 64,73%, Nitrobacter vulgaris mampu mendegradasi amoniak sebesar 62,89% dan Bacilus cereus mampu mendegradasi pospat sebesar 90,96%; (iii) aplikasi konsorsium mikroba sebagai rehabilitasi air sungai Kaliotik berupa suspensi mikroba dengan presentase 2,5% dalam 500 ml air limbah selama 28 hari.
English Abstract
Water pollution, especially river pollution, is now a serious problem that must be addressed. One of the tributaries of the Lamongan river, known as the Kaliotik, is showing signs of being polluted. Pollutants entering the river bed continue to increase, causing water quality to continue to decline. The incoming pollutants come from domestic waste, fish markets and agriculture. Efforts need to be made to carry out rehabilitation to improve water quality. The objectives of this research are (i) to analyze the distribution of water quality pollution zones; (ii) analyzing bacterial isolates and consortia that are capable of degrading LAS, ammonia and phospat compounds; (iii) recommend the application of microbial consortia in rehabilitating the Kaliotic river. The type of research used in this research is quantitative descriptive analysis with a true experimental time series pre-test post test design research design. Analysis of water quality contamination zones is carried out through biotlic index and self-purification. Analysis of pollutant degrading bacterial isolates and consortia through screening and identification of bacterial 16sRNA, as well as analysis of the ability of microbial isolates to degrade pollutant compounds with inhibition zones The results of this research are (i) the distribution of Kaliotic river water quality pollution zones shows that it is heavily polluted with a pollutant index value of 2.74; (ii) bacterial isolates and consortia that have the ability to degrade LAS, ammonia and phospat in the Kaliotic river, Pseudomonas aeruginosa, Nitrobacter vulgaris and Bacilus cereus, Pseudomonas aeruginosa is able to degrade LAS by 64,73%, Nitrobacter vulgaris is able to degrade ammonia by 62,89% and Bacilus cereus was able to degrade phosphate by 90,96%; (iii) application of the microbial consortium as rehabilitation of Kaliotic river water in the form of a microbial suspension with a percentage of 2.5% in 500 ml of waste water for 28 days
