Abstract
ABSTRACT Brown planthopper (Nilaparvata lugens) is one type of insect that causes losses to rice plants. One of the efforts to control the brown planthopper (Nilaparvata lugens) is by using vegetable pesticides. Contribution to this research in the form of posters. Poster is one type of visual media that can be used in the learning process. This study aims to determine the effect of bandotan leaf extract (Ageratum conyzoides L.) on the mortality of brown planthopper (Nilaparvata lugens) so that it can provide information to the public that bandotan can be used as a vegetable pesticide. This study is an experimental study with a completely randomized design (CRD) with 5 treatments and 5 replications. The samples used were brown planthopper (Nilaparvata lugens) withP_0 (DDT 100 ml), P_1 (10%), P_2 (20%), P_3(30%), and P_4 (40%). Observations of dead brown planthopper (Nilaparvata lugens) were carried out for 24 hours and 48 hours. he results showed that within 24 hours at a concentration of 10% the average dead brown planthopper reached 32%, the concentration of 20% reached 48%, the concentration of 30% reached 68% and the concentration of 40% reached 80%. Meanwhile, 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 84% and the concentration of 40% reached 100%. Based on analysis of variance (Ansira) showed that bandotan leaf extract (Ageratum conyzoides L.) had a very significant effect (p > 0.01) on the mortality of brown planthopper (Nilaparvata lugens). The effective concentration to kill the brown planthopper (Nilaparvata lugens) is a concentration of 30%. Then the results of the poster validation in terms of language aspects with a linguist validator obtained a value of 95% with very valid information. Then on the material and media aspects, a value of 100% was obtained with very valid information and the results of the RPP validation obtained a value of 92% with very valid information. Keywords: Bandotan leaf extract (Ageratum conyzoides L.), Brown planthopper (Nilaparvata lugens), Poster.
