| dc.description.abstract | These natural dyes have been used for generations by the Papuan people
before the existence of synthetic dyes to decorate their traditional crafts. Utilizing
Papuan wood as a natural dye not only supports the local economy but also
promotes sustainable practices, as the resources can be obtained locally. In this
study, the types of Papuan wood used are matoa (Pometia pinnata), merbau
(Intsia bijuga), pulai (Alstonia scholaris), Chinese wood (Podocarpus amarus) and
moref (Palaquium amboinense) using two extraction methods, namely hotplate
and vacuum extraction machine which aims to analyze the benefits of the five
types of Papuan wood as natural dyes on fabric media. Based on the research
results of the fastness test, the smallest color difference value is matoa hotplate
for dyeing and moref vacuum extraction for ecoprint. In the Staphylococcus
aureus antibacterial test, the highest antibacterial value on the dyed fabric before
washing was 48.15% while after washing it was 18.52% on the fabric for the
merbau type, on the ecoprint fabric it had no antibacterial value. For
Propionibacterium acnes bacteria, the dyed fabric with hotplate method has a
value of 11.11% while the ecoprint fabric has no antibacterial value. For
antibacterial tests on yields with hotplate and vacuum extraction methods using
Staphylococcus aureus bacteria had the highest antibacterial value of 94.44%
and testing using Propionibacterium acnes bacteria had the highest antibacterial
value of 100.00%. Antioxidant testing on fabrics, the highest value was 94.83%
before washing, 86.77% after washing. For phenolic value, the highest value was
62.87%. | en_US |
