This study aims to analyze the effectiveness of rice straw fiber as a cover of surface soil in slope erosion control. This research was conducted by three variations of rainfall intensity that is 50 mm/hour, 100 mm/hour, 120 mm/ hour. The results of this study indicate the effectiveness of the rice straw fibers in the covered layer with a percentage of 30% reduced when it compared to uncovered layer. The amount of erosion rate withpercentage of 30% or with a dry weight of 38.7 g/m2p have average of 17.068%. In other words, the rate of erosion without covered layer is reduced by an average of 82.932%. Similarly, the effectiveness of the rice straw fibers with a percentage of 60% and 90% or dryweight of 145,1 gr/m2 and 354.8 g/m2 is also reduced when compared to uncovered layer. The amount of erosion rate with a percentage of 60% have an average of 7.216% and the percentage of 90% have an average of 4.392%. In other words, the erosion rate without covered layer is reduced by an average of 92.784% at percentage of 60% and an average of 95.608% at percentage of 90%.
