The study on rattan inventory was done in the area of Semangus Ulu Forest Complex, Forest District of Lematang Musi Ulu, South Sumatra. Some 16 hectares of area which is considered as source of rattan production, was proposively selected as a research area for this study. The standing stock of rattan in the research area was fully enumerated using continuous line plots of 10 meters width and the size of recording unit plots within each was 10 m x 10 m. The total number of line plots was 40 lines each of 400 m length and consisted of 1.600 recording unit plots. Data collected from each recording unit plots consisted of the rattan species, the number of clump, the number of stems and the diameter, length and weight of the stem of each clump. The locations of clumps were mapped. By means of drawn map, two sampling techniques were studied. First, the continuous strip sampling with strip of the 10 m and 20 m width, and sampling intensities of 10, 20 and 25 percent. And second the line plot sampling with plots of 10 m x 10 m and 20 m x 20 m, with sampling intensities of 25 and 10 percents. The results showed that : 1. Within the research area there were 9 rattan species, which consisted of 33 clump and 173 stems per hectare having fresh weight of 578 kg per hectare. 2. The continuous strip sampling method with strip of 10 meters width as sampling unit and 20 percents sampling intensity could be considered as the most adequate for the inventory of rattan potential in the forest complex.
