Abstract

80 376.8 tons of rattan worth US51 840 38 were exported annually from Indonesia from 1977-1981. Rattan was second to wood as a foreign - currency earner. Semi-processed material such as whole canes with or without bark rattan peel or rattan core processed from many species was exported. Several processing methods were used by small rattan manufacturing companies e.g. cutting drying removal of node bulges removal of unwanted material on the surface of canes by mechanical means or heated solvent treatment and chemical bleaching. In general two types of processing were distinguished based primarily on certain properties of the species treated. Siliceons small-diameter rattans were worked on to remove silica by rubbing the cane with fine sand fatty large-diameter rattans undergo a boiling treatment in an oil mixture to remove cutinous material waxes or gums from the canes. Small-diameter rattans were piled or hung during air-drying; large-diameter rattans were stacked or end-racked. 11 types of oil mixtures were used by rattan manufacturers in Sumatra Kalimantan and Sulawesi consisting of diesel oil coconut oil kerosene water sodium nitrate and sulphur. However the effects of different oil mixtures on the quality of rattan canes is not clear. In general such processing prevents biological attack to some extent eliminated cutinous material and gums and speeded up drying of certain rattan species
