Abstract (English) :
Fire as one source of forest disturbance has been known to influence changes on watershed environment condition. The time length of disturbance by forest fire on hydrological condition was I dentified no more than 3 years. The study of the Impact of forest fire in 199711998 on hydrological condition changes at production .Ii"est of state forest plantation (pinus merkusii) was conducted at BKPH PUjon. KPH Malang. PT. Perhutani Unit II East Java. Runoff and SOIl erosion data were collected .tram 6 runoff-Sail erosion model standard plots (2 m x 22 m) and 4 plots of v-notch mini-catchment. The 6 treatments on post fire land of standard plots were: P1 ~ allowed to natural succession. P2 . cultivated and allowed, P3 ~ planted corn. P4 ~ planted king grass, P5 .c planted vegetable crop, and P6 ~ unburned forest (control). The 4 treatments oj' V-notch plots were: TO ~ control (unburned forest), Tl ~ intercropping 'if young pinus + corn + cabbage, T2 ~ intercropping of young pinus + red chili + mustard, and T3 ~ intercropping of corn + mustard + bloemkool. The results indicate that post fire land planted with annual crop (corn), king grass. and vegetable crop tend to increase runoff and soil erosion compare with unburned li"est. The rainfall-runoff and rainfall-soil erosion relationship oj' each treatment show that low power value « 1) at control treatment indicatein increasing rainfall value will not significantly increase runoff or soil loss values, however at post fire landt planted with annual and vegetable crops the power values were higher (> 1) as an indication of increasing rainfall value will significantly increase runoff or soil loss values. An effort to reduce runoff and soil erosion impact afier fhrest fire is needed. e.g., implementing ridge terrace strengthened by grass and or alley cropping.
