Keefektifan Ekstrak Organik Tepung Biji Pinang (Areca Catechu L.) Terhadap Mortalitas Hama Bawang Merah Spodoptera Exigua Hubner Di Laboratorium

---

ABSTRACT
This study aims to determine the effectiveness of organic extracts of areca
nut flour on the mortality of S. exigua in the laboratory. Red onion (Allium
ascalonicum L.) is an agricultural commodity that is widely cultivated in lowlands.
Increasing demand is not matched by optimal production, partly due to attacks by
the pest Spodoptera exigua Hubner, which can cause damage of up to 57%, even
reaching 100% if left uncontrolled. The continuous use of synthetic chemical
insecticides in pest control can have negative effects such as resistance, resurgence,
and the emergence of secondary pests. One environmentally friendly control
alternative is the use of botanical insecticides, such as organic extracts from areca
nut flour (Areca catechu L.). The study was conducted experimentally using a
completely randomized design (CRD) with five concentration treatments (0%,
0.25%, 0.50%, 0.75%, and 1%) and four replicates. The parameters observed
included initial time of death, LT50, LC50, LC95, daily mortality, total mortality,
temperature, and humidity. The results showed that the 0.50% concentration was
the most effective, with a total mortality of 80%, an initial time of death of 6.50
hours, and LT50 achieved 42 hours after application.
Keywords: Botanical pesticide, organic solvent, concentration
