PERBANDINGAN ZAT PEWARNA EKSTRAK DAUN DAN SERASAH TENGKAWANG (Shorea macrophylla Ashton) YANG TERFIKSASI TERHADAP KAYU SENGON (Paraserianthes falcataria (L.) Nielsen)
ABSTRACT: Wood was used as
main component of raw material for sculpture and souvenir in West Kalimantan.
High demand of this product made the artisan used wood with low quality, such
as Sengon wood which has low densities and unsuitable color. Therefore to
overcome the problem they used natural dye from leave of several woods. But the
color still not performs well and easy to leach when the wood has expose to the
light. This research aimed to made a natural dye from leaves and herbs of
Tengkawang wood (Shorea macrophylla Ashton) with fixation materials were CaCO 3
; FeSO 4 an (Kal(SO 4 ) 2 .12H 2 O). Evaluation the durability of color was
conducted according ASTM D 870-02-2002 and ASTM D 1308-02-2013 standard. The
result showed that fixation material increased the color and durability of
natural dye from leaves and herbs. Their values were fulfilling the standard.
Extract from leaves was good from leaching in hot water process but not so good
in cold water and detergen process. Vice versa with the result from extract of
herbs, the value was good on durability from leaching in cold water and
detergen process and not good on hot water process. The natural extract from
leaves and herbs of Tengkawang with fixation process can be used for natural
dye to product of sculpture and souvenir from wood in West Kalimantan.
