The purpose of this research is to know the effectiveness of papaya leaf extract and mahogany seed on grayak caterpillar on pepper plant in vitro. This research is an experimental research with quantitative descriptive data analysis using one-way variance analysis (Oneway Anova). This research consist of 4 treatment with single factor that is extract type (M), M1 = Extract of mahogany seed 20 ml, M2 = 25 ml mahogany extract, M3 = papaya leaf extract 20 ml, M4= papaya leaf extract 25 ml.
