Abstract:
The alternative way of environmentaly friendly weed controlling is to use Chromolaena
odorata and Piper betle extract that contain allelopathic compound and potential as
organic herbicides. The purpose of this research was to know the influence of
Chromolaena odorata and Piper betle extracts in inhibiting the germination and growth
of Mikania micrantha and to determine the best concentration of extracts in weed
controlling. This research used Randomize Complete Design. The collected data was
analyzed using Analysis of Variance (ANOVA), followed by Duncan’s Multiple Range
Test if the result is significantly different. The experiment results showed that the
germination and growth of Mikania micrantha weed were reduced because of the
treatment using Chromolaena odorata and Piper betle extract. The most efficient
extract concentration in controlling weed was 10% of Chromolaena odorata extract
