The research entitled Autecolgical study of Areca vestaria in Sub-Montane Forest Lore Lindu National Park at Toro village area has been conducted from April to May 2016. The objective of the research was to know the biotics and abiotics factor arround the habitat of Areca vestiaria. The results showed that The highest important value index (IVI) of tree, sapling, pole and seedling species wereFicus ampelos (68.69%), Aphanaximis polistachy (40.01%), Ardisia lateriflora (31.73%) and Ardisia lateriflora (19.23%) respectively. The insects  actively interacted with A. vestaria were black ant and bee. Based on soil analyzed indicated that pH  of soil 6.6 while N, P and organic matter concentration  were 0.26, 0.207 mg/g and 76.1% respectively. A. vestaria grew under light intensity of 540.4 lux, humidity of 76.1% and average daily temperature of 24.4%.

This paper adopts a 3-stage rotating biological contactor (RBC), studies kinetic analysis on RBC treatment of organic matter .Water temperature 25 °C and hydraulic retention time (HRT) 5h , COD concentration of influent varies from about 400 to 700mg / L, the average COD removal rate is 85% . According to Monod and Michaelis-Menten formula, organic matter removal kinetics equation in the first stage of RBC can be catched. When DO≥2mg/L, organic matter removal kinetic equation: U1=7.02S1/( S1+640.70), DO<2mg/L, organic matter removal kinetic equation: U2=35.97S2/( S2+4848.92) .Where U is substrate removal rate of unit area of disc, S is the organic matter concentration of substrate. Some reference values of the equation are very useful for practical application of RBC.
