Uji Beberapa Konsentrasi Ekstrak Organik Tepung Daun Sirih Hutan (Piper Aduncum Linn.) Terhadap Mortalitas Larva Kumbang Tanduk (Oryctes Rhinoceros Linn.)

The decline in oil palm (Elaeis guineensis Jacq.) production in Indonesia is caused by several factors, one of which is the attack of the rhinoceros beetle (Oryctes rhinoceros Linn.). Control using synthetic insecticides is the common method used by farmers to control Oryctes rhinoceros L., but it has negative impacts such as the formation of pesticide residues, killing natural enemies, the development of pest resistance and resurgence, and contamination of agricultural commodities. An alternative control method is the use of botanical insecticides from forest betel leaf (Piper aduncum L.). This research aims to determine the effective concentration of organic extract from forest betel leaf against the mortalityof Oryctes rhinoceros L. larvae in the laboratory. The study was conducted experimentally using a completely randomized design (CRD) consisting of six treatments and four replicates. The treatments were 0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1% concentrations oforganic extract from forest betel leaf. The observation parameters included the initial time of death, lethal time 50, lethal concentration 50 and 95, daily mortality rate, total mortality, temperature, and humidity. The results showed that a 1% concentration of organic extract from forest betel leaf is the best concentration for controlling Oryctes rhinoceros L. larvae because it caused a total mortality of 75% with an initial time of death at 30 hours and a lethal time 50 at 78 hours after application. The 0.75% concentration was not effective because it caused a total mortality of less than 80%.
