Electrons can be produced through the degradation of organic substrate materials by electrogenesis bacteria. \u201cElectrogenesis bacteria act as microbes that can decompose organic materials into electrons,\u201d said the doctoral alumnus of Catholic University Leuven, Belgium.<\/p>\n<figure id=\"attachment_98800\" aria-describedby=\"caption-attachment-98800\" style=\"width: 2560px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-98800\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Tampilan-teknologi-microbial-fuel-cell-MFC-yang-memanfaatkan-limbah-tahu-dan-lumpur-Sidoarjo-untuk-menyalurkan-energi-listrik.jpg\" alt=\"Tampilan teknologi microbial fuel cell (MFC) yang memanfaatkan limbah tahu dan lumpur Sidoarjo untuk menyalurkan\u00a0energi\u00a0listrik\" width=\"2560\" height=\"1440\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Tampilan-teknologi-microbial-fuel-cell-MFC-yang-memanfaatkan-limbah-tahu-dan-lumpur-Sidoarjo-untuk-menyalurkan-energi-listrik.jpg 2560w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Tampilan-teknologi-microbial-fuel-cell-MFC-yang-memanfaatkan-limbah-tahu-dan-lumpur-Sidoarjo-untuk-menyalurkan-energi-listrik-300x169.jpg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Tampilan-teknologi-microbial-fuel-cell-MFC-yang-memanfaatkan-limbah-tahu-dan-lumpur-Sidoarjo-untuk-menyalurkan-energi-listrik-1024x576.jpg 1024w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Tampilan-teknologi-microbial-fuel-cell-MFC-yang-memanfaatkan-limbah-tahu-dan-lumpur-Sidoarjo-untuk-menyalurkan-energi-listrik-768x432.jpg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Tampilan-teknologi-microbial-fuel-cell-MFC-yang-memanfaatkan-limbah-tahu-dan-lumpur-Sidoarjo-untuk-menyalurkan-energi-listrik-1536x864.jpg 1536w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Tampilan-teknologi-microbial-fuel-cell-MFC-yang-memanfaatkan-limbah-tahu-dan-lumpur-Sidoarjo-untuk-menyalurkan-energi-listrik-2048x1152.jpg 2048w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Tampilan-teknologi-microbial-fuel-cell-MFC-yang-memanfaatkan-limbah-tahu-dan-lumpur-Sidoarjo-untuk-menyalurkan-energi-listrik-355x200.jpg 355w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><figcaption id=\"caption-attachment-98800\" class=\"wp-caption-text\">The appearance of microbial fuel cell (MFC) technology that utilizes tofu waste and Sidoarjo sludge to generate electrical energy<\/figcaption><\/figure>\n<p>Sources of organic materials used in MFC include food waste, fishery waste, sewage waste, molasses waste, and other wastes. Through the research presented in her scientific oration, Juli utilized electrogenesis culture microbes such as Shewanella oneidensis-MR1 contained in Sidoarjo mud.<\/p>\n<p>Not only the microbial content of electrogenesis, Juli also discovered another potential of Sidoarjo sludge as inorganic waste. In her research, she found the content of rare earth metals (in Indonesian terms, Logam Tanah Jarang, abbreviated and will be referred to as LTJ) that can be utilized to produce electronic devices. \u201cWe focus on extracting LTJ which is very potential and can be used as raw material later,\u201d said the mother of one.<\/p>\n<p>With this research, Juli plans to further optimize MFC technology with a continuous series stacked configuration system so that the generated electrical energy is greater and more stable. Thus, the electricity generated from MFC can be used as an alternative energy source to benefit the community.<\/p>\n<figure id=\"attachment_98798\" aria-describedby=\"caption-attachment-98798\" style=\"width: 1600px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-98798\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Prof-Dr-Ir-Sri-Rachmania-Juliastuti-MEng-guru-besar-ke-204-ITS-menunjukkan-buku-orasi-ilmiahnya-yang-disampaikan-dalam-sidang-pengukuhan-profesornya.jpg\" alt=\"Prof Dr Ir Sri Rachmania Juliastuti MEng, guru besar ke-204 ITS menunjukkan buku orasi ilmiahnya yang disampaikan dalam sidang pengukuhan\u00a0profesornya\" width=\"1600\" height=\"900\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Prof-Dr-Ir-Sri-Rachmania-Juliastuti-MEng-guru-besar-ke-204-ITS-menunjukkan-buku-orasi-ilmiahnya-yang-disampaikan-dalam-sidang-pengukuhan-profesornya.jpg 1600w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Prof-Dr-Ir-Sri-Rachmania-Juliastuti-MEng-guru-besar-ke-204-ITS-menunjukkan-buku-orasi-ilmiahnya-yang-disampaikan-dalam-sidang-pengukuhan-profesornya-300x169.jpg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Prof-Dr-Ir-Sri-Rachmania-Juliastuti-MEng-guru-besar-ke-204-ITS-menunjukkan-buku-orasi-ilmiahnya-yang-disampaikan-dalam-sidang-pengukuhan-profesornya-1024x576.jpg 1024w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Prof-Dr-Ir-Sri-Rachmania-Juliastuti-MEng-guru-besar-ke-204-ITS-menunjukkan-buku-orasi-ilmiahnya-yang-disampaikan-dalam-sidang-pengukuhan-profesornya-768x432.jpg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Prof-Dr-Ir-Sri-Rachmania-Juliastuti-MEng-guru-besar-ke-204-ITS-menunjukkan-buku-orasi-ilmiahnya-yang-disampaikan-dalam-sidang-pengukuhan-profesornya-1536x864.jpg 1536w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2025\/02\/Prof-Dr-Ir-Sri-Rachmania-Juliastuti-MEng-guru-besar-ke-204-ITS-menunjukkan-buku-orasi-ilmiahnya-yang-disampaikan-dalam-sidang-pengukuhan-profesornya-355x200.jpg 355w\" sizes=\"(max-width: 1600px) 100vw, 1600px\" \/><figcaption id=\"caption-attachment-98798\" class=\"wp-caption-text\">Prof. Dr. Ir.
