The experiment was conducted to find out the effect of terrace types and elephant grass (Pennisetum purpureum) on erosion, aggregate stability, and permeability of Typic Hapludalfs. The experiment was done in the rainy season in Sukamulya village, Sukamakmur, Bogor, West Java with the altitude of 800 m above sea level and slope of 30%. Randomized block design was used in this experiment, consist of 5 treatments and 3 replications. Treatments were: without terrace and without grass (T0) as a control, dike terrace without grass (T1), dike terrace with grass (T2), bench terrace without grass (T3), and bench terrace with grass (T4). The results Showed that, there were highly significant difference effect of terrace types and grass (Pennisetum purpureum) on erosion, soil aggregate stability, and soil permeability. The treatment of the bench terrace with elephant grass (T4) gave the lightest eroded soil of 6.698 t ha-1. The decreasing value on aggregate soil stability and soil permeability were significantly affected by increasing erosion. These relationships were very closed, showed on the coefficients of regression determination of 96% and 97% respectively. Meanwhile the increasing of rainfall followed significantly by increasing of erosion, with a regression determination coefficient of 99%. The result of this study, showed that, there were significantly correlated between erosion with soil aggregate stability, soil permeability, and rainfall.
