Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)

abstract Excessive surface runoff, can caused floods and soil erosion. Vegetation canopy can reduce surface runoff with intercept the precipitations. This study aims to determine the amount of interception, by measuring the amount of steam flow and through fall. Thus, it will obtain information on appropriate tree species used for reforestation or afforestation. This research was conducted at the University of Lampung on May-June 2010, by using Randomized Complete Block Design, which consists of 3 treatment (Acacia auriculiformis, Hevea brasiliensis, and Filicium decipiens). Each treatment was repeated 9 times, in order to obtain 27 units of the experiment. Rain observation periods conducted during the 5 days of rain. Data were analyzed with analysis of variance and further using BNT test. The results obtained for the effect of treatments on the interception, steam flow, and through fall indicates that there are real differences in the level 5%. The biggest interception values found on Filicium decipiens 9.87 mm (37.21%), then Acacia auriculiformis and Hevea brasiliensis, amounting to 7.63 mm (28.76%) and 6.39 mm (24.08%). The biggest steam flow values found on Hevea brasiliensis 0.03 mm (0.113%), then Acacia auriculiformis and Filicium decipiens, amounting to 0.010 mm (0.039%) and 0.005 mm (0.018%). While the biggest through fall values found on Acacia auriculiformis 20.13 mm (75.88%), then Hevea brasiliensis and Filicium decipiens, amounting to 18.87 mm (71.12%) and 16.65 mm (62.77%). Key words: interception, steam flow, through fall.
