ABSTRACT
Rice plant (Oryza sativa L.) is an important food crop commodity in Indonesia,
providing calories and nutrients as a staple food for the Indonesian people. Rice
cultivation is inseparable from pest attacks, which have a significant impact on
decreasing rice production. One such pest is the brown planthopper (Nilaparvata
lugens Stal.), which can cause total crop failure. One plant with potential as a
botanical pesticide is the japanese papaya (Cnidoscolus aconitifolius I.M.
Johnst.). This study aims to determine the effective concentration of organic leaf
extract of japanese papaya against the mortality of brown planthoppers. This
research was conducted at the Plant Pest Laboratory, Faculty of Agriculture,
University of Riau, from November to December 2024, using a completely
randomized design (CRD) consisting of five treatment concentrations with four
replications. The treatments given were Japanese papaya leaf extract with the
following concentrations: P0: 0%, P1: 0.25%, P2: 0.50%, P3: 0.75%, and P4:
1%. Observation parameters consisted of initial time of death, lethal time 50,
lethal concentration (LC50 and LC95), daily mortality, total mortality, temperature
and humidity. The results showed that the application of japanese papaya leaf
extract had a significant effect on the mortality of brown planthoppers. The most
effective concentration was 0.50%, with a total mortality rate reaching 82.50%,
an initial mortality time of 4.50 hours after application, and an LT50 (lethal time
for 50% mortality) at 29.50 hours after the application of the botanical pesticide.
