Soft and stretchable electronic devices are expected to offer technological advances in the field of robotics, human–machine interfacing, healthcare. Employing biodegradable elastomers, hydrogels, nontoxic conductors would add significant value minimize ecological impact such disposable transient applications. Here, photo-crosslinkable elastomer poly(glycerol sebacic) acrylate (PGSA) is charact...

Batik is a unique ethnic and heritage textile from Indonesia with low biodegradability (BOD5/COD) demanding biological wastewater treatment. However, in its application high value needed. To increase the ozonation process can be used as pre-treatment. The purpose of this study to determine effectiveness ozone pre-treatment color removal, COD changes biodegradability. This was divided into two t...

In this research, polyvinyl alcohol (PVA)-chitosan composite films were produced using nanocellulose from coconut fibers (Cocos nucifera) in an Indonesian plantation order to enhance mechanical properties and biodegradability. The process began by separating lignin hemicellulose delignification, bleaching, then cellulose hydrolysis produce nanocellulose. PVA was mixed with chitosan specific com...
