In polluted seawater samples taken from Madura waters, the TPH value was 2,600-3,000 mg\/L. In comparison, the TPH value for a suitable environment was 1,000 mg\/L or below 1 percent. &#8220;This means that the seawater in the area is very polluted,&#8221; she said.<\/p>\n<p style=\"text-align: justify\"><span data-preserver-spaces=\"true\">Biodegradation in this study utilizes the bacteria\u00a0<\/span><em><span data-preserver-spaces=\"true\">Bacillus subtilis<\/span><\/em><span data-preserver-spaces=\"true\">\u00a0and\u00a0<\/span><em><span data-preserver-spaces=\"true\">Pseudomonas putida<\/span><\/em><span data-preserver-spaces=\"true\">. Harmin explained that his research used a stepwise method, where this method is a combination method of adding two bacteria. For example, the combination uses\u00a0<\/span><em><span data-preserver-spaces=\"true\">Pseudomonas putida\u00a0<\/span><\/em><span data-preserver-spaces=\"true\">bacteria to decompose the sample first, then added <em>Bacillus subtilis<\/em> bacteria.<\/span><\/p>\n<p>The purpose of using this method is to determine the effectiveness of bacteria in decomposing chemical compounds with high levels of pollutants. Pollutant samples have decomposed as much as 66 percent in 35 days of laboratory testing. &#8220;This combination has a higher effectiveness in breaking down bacteria,&#8221; Harmin said.<\/p>\n<p>In addition, Harmin also said that in addition to the type of bacteria that is effectively used to decompose pollutants, there are additional nutrients as other food for bacteria. These nutrients are obtained from fertilizers that contain the chemical elements nitrogen, phosphorus, and potassium. The function of these nutrients is to accelerate the decomposition process of pollutants in the sample.<\/p>\n<figure id=\"attachment_66366\" aria-describedby=\"caption-attachment-66366\" style=\"width: 1280px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-66366\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/03\/WhatsApp-Image-2022-03-01-at-16.30.39.jpeg\" alt=\"Ilustrasi pencemaran polutan minyak bumi di laut (sumber dari Jawapos.com)\" width=\"1280\" height=\"803\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/03\/WhatsApp-Image-2022-03-01-at-16.30.39.jpeg 1280w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/03\/WhatsApp-Image-2022-03-01-at-16.30.39-300x188.jpeg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/03\/WhatsApp-Image-2022-03-01-at-16.30.39-1024x642.jpeg 1024w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/03\/WhatsApp-Image-2022-03-01-at-16.30.39-768x482.jpeg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/03\/WhatsApp-Image-2022-03-01-at-16.30.39-355x223.jpeg 355w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><figcaption id=\"caption-attachment-66366\" class=\"wp-caption-text\">Illustration of petroleum pollutant pollution in the sea (source from Jawapos.com)<\/figcaption><\/figure>\n<p>The researcher also stated that the advantages of this biodegradation are the bacteria Bacillus subtilis and Pseudomonas putida, each of which can decompose pollutants very well, combined into one in this study.
