Mimosa invisa plant is a weed that is able to grow quickly in large numbers in the area of sugar cane plantations, which can cause a decrease in the quantity and quality of the harvest and the difficulty of the harvesting process. Mimosa invisa plants are class A weeds, where their effects on plantation crops are very significant. Mimosa invisa has great competitiveness with main plants, which is able to increase population efficiency by 14.08% in the first year to 38.55% in the third year. Sugarcane (Saccharum officinarum L) is a shrub that is used as a source of sweeteners. The study was conducted to determine secondary metabolite compounds as allelochemicals in the Mimosa invisa rhizosphere and sugar cane plants. The study was conducted using a qualitative descriptive design through the identification of secondary metabolite compounds and Mimosa invisa allelochemistry and sugar cane. Samples were analyzed in the rhizosphere of monoculture weed, monoculture sugarcane, polyculture weed. Compound analysis using the Gass Cromatografy Mass Spectrophotometry (GCMS) Tool. The results showed that some allelochemical compounds in the rhizosphere of weeds and sugar cane could inhibit growth as well as potentially being developed as bioherbicides because they have inhibitory properties in certain environments.
