Brown planthopper (Nilaparvata lugens) is a pest that can caused rice to be harvest failure. One of the methods used to control brown leafhoppers is by using plantbased pesticides. Contributions to this research are in the form of posters. Posters are large, medium or small images and tell or announce through simple and clear visual text. This study aims to determined the optimum concentration of papaya’s leaf extract (Carica papaya) which is best used for the mortality of brown planthopper (Nilaparvata lugens). This study is an experimental study with a completely randomized design (RAL) with 5 treatments and 5 replications. The samples used were brown planthoppers treated with P0 (DDT), P1 (10%), P2 (20%), P3 (30%), P4 (40%). Observations of dead brown planthoppers were carried out for 24 hours and 48 hours. The results showed that within 24 hours at a concentration of 10% the average dead brown planthopper reached 24%, the concentration of 20% reached 48%, the concentration of 30% reached 64%, the concentration of 40% reached 80%, whereas within 48 hours at a concentration of 10% the average dead brown planthopper reached 44%, the concentration of 20% reached 68%, the concentration of 30% reached 80%, 40% reached 100%. Based on analysis of variance (Ansira) showed that papaya’s leaf extract (Carica papaya) had a very significant effect (p > 0.01) on the mortality of brown planthoppers. The effective concentration to kill the brown planthopper is a concentration of 30%. The results of the validation of learning media in the form of posters in terms of several aspects of language with linguist lecturers obtained an average score of 95 with very valid information. In the material aspect, an average score of 100 was obtained with very valid information. In the aspect of media display, an average score of 100 was obtained with a very valid description. As for the results of the RPP validation, an average score of 89 was obtained with valid information. Keywords: Papaya’s leaf (Carica papaya), Brown planthopper, Posters
