Due to these mining activities, according to Bieby, the soil around the mining area is contaminated with crude oil, petroleum hydrocarbon compounds, as well as Benzene, Toluene, Ethylbenzene, and Xylene (BTEX) compounds.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Furthermore, Prof Bieby elaborated that these compounds are hazardous and toxic waste (B3) that can adversely affect the health of the local community. &#8220;Therefore, remediation technology is necessary to restore the land to its original condition,&#8221; she emphasized.<\/span><\/p>\n<figure id=\"attachment_88009\" aria-describedby=\"caption-attachment-88009\" style=\"width: 1000px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-88009\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.21.46_9d4118e3.jpg\" alt=\"Kondisi tanah tercemar akibat aktivitas penambangan liar di Wonocolo, Bojonegoro yang mendapat julukan\u00a0Little\u00a0Texas\" width=\"1000\" height=\"563\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.21.46_9d4118e3.jpg 1000w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.21.46_9d4118e3-300x169.jpg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.21.46_9d4118e3-768x432.jpg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.21.46_9d4118e3-355x200.jpg 355w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><figcaption id=\"caption-attachment-88009\" class=\"wp-caption-text\">The contaminated soil condition due to illegal mining activities in Wonocolo, Bojonegoro, which has earned the nickname &#8220;Little Texas.&#8221;<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400\">In her research for her inaugural professorial lecture, Bieby utilized a biologically based remediation method combined with a physicochemical method. The physicochemical method involves the use of soil washing processing, aimed at separating the soil from crude oil and petroleum hydrocarbons. Meanwhile, the biological method functions to reduce the concentration of chemicals such as BTEX, nitrogen, cadmium, and mercury.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Bieby explained that the soil washing method is effective in reducing the oil content in the soil from 4 percent to less than 1 percent. Furthermore, the biological remediation method using the bacteria Bacillus cereus, Nitrosomonas communis, and Pseudomonas aeruginosa has shown a chemical concentration reduction ranging from 40 percent to 70 percent.<\/span><\/p>\n<p><span style=\"font-weight: 400\">The selection of the biological method was made because the land in Indonesia already contains bacteria capable of naturally restoring pollution. Bieby revealed that with this research, it is expected to expedite the recovery process. &#8220;Moreover, biological methods tend to be more cost-effective and do not produce chemical waste,&#8221; stated the professor.<\/span><\/p>\n<figure id=\"attachment_88008\" aria-describedby=\"caption-attachment-88008\" style=\"width: 1280px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-88008\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.20.55_1b07aed6.jpg\" alt=\"Ketua Dewan Profesor ITS Prof Dr Imam Robandi MT (kiri) ketika menyerahkan sertifikat pengukuhan Guru Besar ITS ke-195 kepada Prof Bieby Voijant Tangahu\u00a0ST\u00a0MT\u00a0PhD\" width=\"1280\" height=\"724\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.20.55_1b07aed6.jpg 1280w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.20.55_1b07aed6-300x170.jpg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.20.55_1b07aed6-1024x579.jpg 1024w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.20.55_1b07aed6-768x434.jpg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/01\/WhatsApp-Image-2024-01-11-at-15.20.55_1b07aed6-355x201.jpg 355w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><figcaption id=\"caption-attachment-88008\" class=\"wp-caption-text\">Chairman of the ITS Professor Council, Prof Dr Imam Robandi MT (left), presenting the certificate of appointment as the 195th Professor at ITS to Prof. Bieby Voijant Tangahu ST MT PhD.<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400\">Although this research is still at the laboratory scale, Bieby revealed that environmental recovery using the biological method has shown high efficiency. &#8220;In the future, this research will be mass-produced for direct application in various polluted areas,&#8221; said the lecturer who has been actively teaching since 1997.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Through this research, Prof Bieby aims to continue developing environmental remediation technology by harnessing bacteria to assist in restoring pollution caused by mining activities. &#8220;I hope that with the advancement of this knowledge, it can contribute to improving environmental quality,&#8221; she concluded optimistically. <strong>(ITS Public Relations)<\/strong><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Reporter: Regy\u00a0Zaid\u00a0Zakaria<\/strong><\/p>\n<p><strong>Translator: Marcellius Fernando R<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>ITS Campus, ITS News \u2013The surge in mining industry activities poses environmental pollution risks.
