She says efficiency in extracting raw materials, processing, and making final products must be maximized. &#8220;The point is how to increase the added value of products with materials that are easy to obtain,&#8221; explained Widi.<\/p>\n<p><span style=\"font-weight: 400\">Based on this, the Professor from the<\/span>\u00a0<a href=\"http:\/\/its.ac.id\/kimia\" target=\"_blank\" rel=\"noopener\">ITS Chemical Engineering Department <\/a><span style=\"font-weight: 400\">utilized the abundant biomass waste around her to create products that can be applied to food, energy, and health. Using avocado seeds as sample material, Widi applies aerosol technology to optimize product usability.<\/span><\/p>\n<p><span style=\"font-weight: 400\">This woman from Surabaya microencapsulated avocado seed extract in powder form in the food sector. Avocado seeds, which are rich in antioxidants, are susceptible to oxidation and sensitive to heat and light. Therefore, Widi applied a spray drying process to cover the avocado seed extract with a polymer matrix as a core coating to protect the compounds inside.<\/span><\/p>\n<div class=\"mceTemp\"><\/div>\n<figure id=\"attachment_89113\" aria-describedby=\"caption-attachment-89113\" style=\"width: 1024px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-89113\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Widyastuti-ST-MT-saat-uji-coba-purwarupa-generasi-I-Baterai-Al-Udara-ITS.jpg\" alt=\"Prof Dr Widyastuti ST MT saat uji coba purwarupa generasi I Baterai\u00a0Al-Udara\u00a0ITS\" width=\"1024\" height=\"579\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Widyastuti-ST-MT-saat-uji-coba-purwarupa-generasi-I-Baterai-Al-Udara-ITS.jpg 1024w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Widyastuti-ST-MT-saat-uji-coba-purwarupa-generasi-I-Baterai-Al-Udara-ITS-300x170.jpg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Widyastuti-ST-MT-saat-uji-coba-purwarupa-generasi-I-Baterai-Al-Udara-ITS-768x434.jpg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Widyastuti-ST-MT-saat-uji-coba-purwarupa-generasi-I-Baterai-Al-Udara-ITS-355x201.jpg 355w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption id=\"caption-attachment-89113\" class=\"wp-caption-text\"><span style=\"font-weight: 400\">Prof Dr Widyastuti ST MT testing the ITS Al-Udara Battery generation I prototype<\/span><\/figcaption><\/figure>\n<p><span style=\"font-weight: 400\">This woman, who also serves as the Head of the<\/span> <a href=\"http:\/\/its.ac.id\/kimia\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400\">ITS Chemical Engineering Department<\/span><\/a>, <span style=\"font-weight: 400\">is also part of the team that developed the ITS Al-Udara Battery Generation I. The remaining material from the extraction of avocado seeds is used for the electrocatalyst process in aluminum-air batteries. &#8220;Because it still contains cellulose, we can still use avocado seed waste,&#8221; she said<\/span>.<\/p>\n<p><span style=\"font-weight: 400\">Furthermore, Widi explained that the material process used is carbonization, namely heating the material in a hydrothermal reactor at 200 Celsius for 12 hours. From this process, avocado seed waste produces a type of carbon that has good characteristics as an electrocatalyst. Electrocatalyst work tests show that the oxygen reduction reaction with aluminum produces sufficient current to supply battery power.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Highlighting performance advantages, ITS Al-Udara Batteries are used as the main energy source for electric vehicles. Metal air batteries are considered cheaper, lighter, environmentally friendly, have a relatively higher energy density, and have better safety factors than conventional batteries. &#8220;We hope to develop a type of secondary battery whose power can be recharged,&#8221; said Widi.<\/span><\/p>\n<figure id=\"attachment_89111\" aria-describedby=\"caption-attachment-89111\" style=\"width: 1600px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-89111\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Eng-Widiyastuti-ST-MT-menjelaskan-hasil-penelitiannya-dalam-buku-orasi-ilmiah-yang-berjudul-Inovasi-Proses-Material-Untuk-Kemajuan-Indonesia.jpg\" alt=\"Prof Dr Eng Widiyastuti ST MT menjelaskan hasil penelitiannya dalam buku orasi ilmiah yang berjudul Inovasi Proses Material Untuk Kemajuan\u00a0Indonesia\" width=\"1600\" height=\"900\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Eng-Widiyastuti-ST-MT-menjelaskan-hasil-penelitiannya-dalam-buku-orasi-ilmiah-yang-berjudul-Inovasi-Proses-Material-Untuk-Kemajuan-Indonesia.jpg 1600w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Eng-Widiyastuti-ST-MT-menjelaskan-hasil-penelitiannya-dalam-buku-orasi-ilmiah-yang-berjudul-Inovasi-Proses-Material-Untuk-Kemajuan-Indonesia-300x169.jpg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Eng-Widiyastuti-ST-MT-menjelaskan-hasil-penelitiannya-dalam-buku-orasi-ilmiah-yang-berjudul-Inovasi-Proses-Material-Untuk-Kemajuan-Indonesia-1024x576.jpg 1024w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Eng-Widiyastuti-ST-MT-menjelaskan-hasil-penelitiannya-dalam-buku-orasi-ilmiah-yang-berjudul-Inovasi-Proses-Material-Untuk-Kemajuan-Indonesia-768x432.jpg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Eng-Widiyastuti-ST-MT-menjelaskan-hasil-penelitiannya-dalam-buku-orasi-ilmiah-yang-berjudul-Inovasi-Proses-Material-Untuk-Kemajuan-Indonesia-1536x864.jpg 1536w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2024\/03\/Prof-Dr-Eng-Widiyastuti-ST-MT-menjelaskan-hasil-penelitiannya-dalam-buku-orasi-ilmiah-yang-berjudul-Inovasi-Proses-Material-Untuk-Kemajuan-Indonesia-355x200.jpg 355w\" sizes=\"(max-width: 1600px) 100vw, 1600px\" \/><figcaption id=\"caption-attachment-89111\" class=\"wp-caption-text\"><span style=\"font-weight: 400\">Prof Dr Eng Widiyastuti ST MT explaining the results of her research in a scientific oration book entitled Inovasi Proses Material Untuk Kemajuan Indonesia (English: Material Process Innovation for the Progress of Indonesia)<\/span><\/figcaption><\/figure>\n<p>W<span style=\"font-weight: 400\">idi added that the research she carried out also developed seawater aluminum batteries. Taking advantage of Indonesia&#8217;s potential as a maritime country, the battery is activated by seawater, which functions as an electrolyte.

By adding gelatin and citric acid, the material is molded to form a wound dressing product that is considered effective after the antibacterial test analysis process.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Through innovations in aerosol science and material processing, Widi hopes Indonesia can be independent regarding health, energy, and food.
