Abstract
Rattan is a non-timber forest product with great economic value. Therefore, this study aims to determine the quality of non-traded rattan from Central Sulawesi based on the morphological characters of the rods. It was carried out to choose alternative speciess of rattan suitable as raw materials to fulfill the increasing demand. A descriptive method was used with wet rattan specimens obtained from natural forests as study materials to determine the quality species and levels. Moreover, complete identification and determination of morphological characters were used to determine the specific species, while the quality was determined based on the internode length, diameter, cylindricity, color, groove depth (texture), and surface appearance of the rod. Data analysis was carried out using analysis of variance followed by a mean difference test, using the SPSS Version 21 program. The results showed that the morphological characters of the 10 rattan speciess were distinctively different, therefore, it was used as determinants of all variables studied. Based on the results, the non-traded rattan with a relatively similar quality as the favorite traded speciess include Calamus insignis, C. minahasae, C. koordersianus, C. leptostachyus, Daemonorops lamprolepsis, D. robusta and D. macroptera.
