Uji Beberapa Konsentrasi Ekstrak Sirih Cina (Peperomia Pellucida L.) Untuk Mengendalikan Hama Walang Sangit (Leptocorisa Acuta Thunberg) Pada Tanaman Padi Gogo (Oryza Sativa L.)

ABSTRACT
Rice (Oryza sativa L.) is the main food source for the Indonesian people, so increasing its production is crucial to meet national food needs. Declining rice production often occurs due to attacks by plant pests, one of which is the stink bug (Leptocorisa acuta Thunberg). This pest control generally uses synthetic insecticides that have the potential to cause resistance and have negative impacts on the environment. As an alternative, botanical insecticides from the chinese betel leaf (Peperomia pellucida L.) can be used to suppress the pest population. This study aims to determine the effective concentration of chinese betel leaf extract in controlling the stink bug on upland rice (Oryza sativa L.). The study was conducted experimentally using a completely randomized design (CRD) with five concentration treatments (0, 25, 50, 75, and 100 g/l of water) and consisted of four replications. Observation parameters included changes in morphology and behavior of nymphs, initial time of death, lethal time 50 (LT₅₀), lethal concentration 50 and 95 (LC₅₀ and LC₉₅), daily mortality, and total mortality. The results showed that a concentration of 100 g/l of chinese betel leaf extract was the most effective treatment with a total mortality of 82.50%, an initial time of death of 13.25 hours after application, and an LT₅₀ of 49.25 hours after application. The LC₅₀ value of chinese betel leaf extract was 4.13%. Thus, chinese betel leaf extract has the potential as an alternative botanical insecticide to control stink bug in upland rice.
