Abstract/Executive Summary

The increasing risk of soil erosion and water vulnerability in urban and slope areas calls for sustainable solutions. This study investigated the effectiveness of lemongrass (Cymbopogon citratus) in reducing soil erosion and water runoff, aiming to explore its potential as a green infrastructure for slope stabilization and water management. The study used a quantitative experimental design to evaluate the effects of lemongrass on soil loss and water vulnerability under controlled simulated rainfall conditions. The research analyzed soil elevation changes and water flow rates, discussed factors that influenced effectiveness, and identified limitations in the experimental setup. Observations indicated that the roots were firm and healthy. The results of independent t-tests indicated that lemongrass did not significantly reduce soil loss (treatment M = 1.06, control M = 0.87, p = 0.6837) or water runoff (treatment M = 49.47, control M = 65.03, p = 0.0504). Based on these findings, the lemongrass showed potential to reduce soil erosion and water runoff, but no statistically significant effects were observed under controlled conditions, likely due to short growth periods, low vegetation coverage, and small sample size.
