POTENSI EKSTRAK DAUN Chromolaena odorata (L.) DAN Piper betle (L.) SEBAGAI HERBISIDA ORGANIK TERHADAP PENGHAMBATAN PERKECAMBAHAN DAN PERTUMBUHAN Mikania micrantha

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
