ABSTRACT This study aims to test the extract of mahogany leaf (Swietenia mahagoni (L.) Jacq.) against maman ungu weed (Cleome rutidosperma D.C.). The research used RAL (Complete Random Design) with concentration 0%, 10%, 20%, 30%, 40%, 50%, and 60% with 4 replications. The variables in this study were plant height, wet weight, number of leaves, chlorophyll content a, chlorophyll content b, and total chlorophyll content. Homogeneity test was using Bartlett test, then analyzed using ANOVA (Analysis of Variance) statistic at 5% (p < 0,05) if there is real difference followed by BNT test at 5% real level. The results showed extract of mahogany leaves with a concentration of 10% effective to inhibit the growth of height and number of leaves, while the concentration of 20% inhibit wet weight of maman ungu weeds.The higher the concentration used, the more effective the mahogany leaf extract is to inhibit the growth of maman ungu weeds. The extract of mahogany leaves has not affected the maman ungu weeds chlorophyll content. Keywords: Bioherbicide, Weeds, Swietenia mahagoni (L.) Jacq., Cleome rutidosperma D.C.)
