Re-designing Conventional Face Mask by Using Triz (Teoriya Resheniya Izobreatatelskikh Zadatch) Method

New Normal becomes the way out to keep Indonesia's weakened economy because of covid-19 pandemic stays in balance. Of course, must be well-balanced with application strict protocols reduce transmission rates and anticipate a surge new cases. From few points protocols, using face mask is considered as most-effective basic need. Re-designing aiming at eliminating worsening feature developing improving feature. This research widely used 1-ply mask, which doesn't meet WHO standard regarding cloth-material that made 3-ply. The method this TRIZ (Teoriya Resheniya Izobreatatelskikh Zadatch), an inventive problem solving theory issues ideas, products, or concepts, case redesigning concept. In research, data are collected by doing library obtain secondary will processed qualitative quantitative methods. results show aspects should eliminated from brittle for being easily damaged, short period usage, non-reusable. After concept carried principles features method, some such weight, material, design, functionality developed. result relatively light weight PLA+filament-based material good durability environmentally friendly. design has longer user only needs replace additional inserted tissue every 4 hours. researchers hope can further developed government deal other possibilities future.
