Paper and plastic used by households until now still has great potential to become waste that threatens the balance of the natural ecosystem. Therefore, the Student Executive Board (BEM) of the Faculty of Mathematics and Natural Sciences (FMIPA) IPB University once again held the “G-Tar (G-Trash Care)” activity for the third time online (29/7). This third series concludes G-Tar 2020 activities. G-Tar is an environmental activity that includes webinars and handicraft making classes from used goods.
