organic waste that is left alone could damage the environment because of the decay reaction. Therefore, mango peel extract is used as an organic inhibitor to prevent corrosion of ASTM A36 carbon steel which is widely used in the petroleum and shipping industries. &#8220;This innovation can overcome the main problem in the use of steel, namely the occurrence of corrosion due to seawater (NaCl),&#8221; he said.<\/span><b><\/b><\/p>\n<figure id=\"attachment_63269\" aria-describedby=\"caption-attachment-63269\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-63269 size-large\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Ekstrak-kulit-mangga-yang-sedang-melalui-proses-penguapan-menggunakan-evaporator-1024x576.jpeg\" alt=\"Ekstrak kulit mangga yang sedang melalui proses penguapan menggunakan evaporator\" width=\"1024\" height=\"576\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Ekstrak-kulit-mangga-yang-sedang-melalui-proses-penguapan-menggunakan-evaporator-1024x576.jpeg 1024w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Ekstrak-kulit-mangga-yang-sedang-melalui-proses-penguapan-menggunakan-evaporator-300x169.jpeg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Ekstrak-kulit-mangga-yang-sedang-melalui-proses-penguapan-menggunakan-evaporator-768x432.jpeg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Ekstrak-kulit-mangga-yang-sedang-melalui-proses-penguapan-menggunakan-evaporator-355x200.jpeg 355w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Ekstrak-kulit-mangga-yang-sedang-melalui-proses-penguapan-menggunakan-evaporator.jpeg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption id=\"caption-attachment-63269\" class=\"wp-caption-text\"><span style=\"color: #0e101a\">Mango peel extract which is going through the evaporation process using an evaporator<\/span><b><\/b><\/figcaption><\/figure>\n<p>A team consisting of students from ITS Chemistry Department. This study chose mango skin because it contains many organic compounds, namely flavonoid compounds included in antioxidant mixtures. This flavonoid compound has a role as a hydrogen donor by donating a reducing group from the hydroxyl group attached to the aromatic ring to delocalize radical compounds.<\/p>\n<p>The student, who is often called Ikbal, also explained using the mango peel extract. Initially, the mango skin separated from the fruit is cleaned with running water. The wet mango skin is then dried, and the section is taken using the maceration method. After that, mango peel extract was obtained, which was then mixed with acrylic resin. &#8220;The last stage is a coating on ASTM A36 low carbon steel,&#8221; said Ikbal.<\/p>\n<p>The team, consisting of students from the 2018 batch of students, has tested the corrosion rate using the PGSTAT302N Autolab instrument. These tests found that the use of mango peel extract can withstand the corrosion rate of 1.12 x 10-7 millimeters per year with an efficiency of 99.999 percent.<\/p>\n<figure id=\"attachment_63268\" aria-describedby=\"caption-attachment-63268\" style=\"width: 521px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-63268 size-large\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Proses-filtrasi-ekstrak-kulit-mangga-521x1024.jpeg\" alt=\"Proses filtrasi ekstrak kulit mangga\" width=\"521\" height=\"1024\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Proses-filtrasi-ekstrak-kulit-mangga-521x1024.jpeg 521w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Proses-filtrasi-ekstrak-kulit-mangga-153x300.jpeg 153w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Proses-filtrasi-ekstrak-kulit-mangga-163x320.jpeg 163w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2021\/10\/Proses-filtrasi-ekstrak-kulit-mangga.jpeg 651w\" sizes=\"(max-width: 521px) 100vw, 521px\" \/><figcaption id=\"caption-attachment-63268\" class=\"wp-caption-text\"><span style=\"color: #0e101a\">Mango peel extract filtration process<\/span><b><\/b><\/figcaption><\/figure>\n<p style=\"text-align: justify;background: white;margin: 0in 0in 7.5pt 0in\"><span style=\"color: #0e101a\">Even though they can only participate in online competitions, the ITS Platinum Team can still feel the excitement of the event with a virtual booth that can be accessed online through the Taiwan Innotech Expo website.
