Ketahanan Sifat Antibakteri Kain Batik Teraplikasi Nanopartikel ZnO
Abstract
Batik has became a part of Indonesian life since ancient times. Nowadays batik is used in daily life both as clothing and household appliances. Therefore it is very important to develop antibacterial batik. This paper presents the results of antibacterial durability tests on batik after repeated laundering. Antibacterial batik was made by applying ZnO nanoparticles to the fabric before and after the batik process using the pad-dry-cure method. Antibacterial properties were tested using the agar diffusion method by measuring the zone of growth inhibition of the Staphylococcus aureus bacteria around the ZnO applied batik cloth. Antibacterial durability was tested by the Launder-O-meter method according to SNI ISO 105-C06:2010. Laundering test was done 4 times which is equivalent to 20 times home laundering. The test results showed that batik which was applied by ZnO nanoparticles before the batik process showed a decrease in antibacterial activity by 78.68% while batik which was applied by ZnO nanoparticles after the batik process showed a decrease in antibacterial activity by 44.74%. Application of ZnO nanoparticles can provide antibacterial properties in batik cloth with a durability of more than 20 times home laundering.
