Pemanfaatan Sirih Hutan (Piper Aduncum Linn) Untuk Mengendalikan Hama Bekicot (Achatina Fulica Ferussac) Pada Persemaian Tanaman Kelor (Moringa Oleifera Lamk)
Moringa is an excellent plant that has been widely developed in Indonesia.
One constraint in the moringa nursery is the snail (Achatina fulica Fer.) attack.
Synthetic chemical pesticides that are mostly practiced give negative impacts on
the environment. Therefore, alternative environmentally oriented pest control is
critically required. Here, I used biopesticide extracted from forest betel (Piper
aduncum Linn.) to control moringa main pest in the nursery, namely snail
(Achatina fulica). This study aimed to obtain the best doses of the betel forest
extract, the effective concentration, and the best spraying interval.
The research was conducted in the Research and Development Forest
Fiber Technology Institute (RDFFTI) nursery and Technical Implementation Unit
(TIU) of Experimental Garden, Faculty of Agriculture, University of Riau, from
September 2022 until May 2023. Three stages of the research experiment were: 1)
Testing extract of forest betel plant part against snail, using a Completely
Randomized Design (CRD) with three treatments and five replications so that I
have 15 experimental units. The treatments were forest betel leaf extract, fruit,
and twig. 2) In order to test the concentration of forest betel leaf extract against
snails, I used CRD with six treatments and four replications to obtain 24
experimental units. The treatments were concentration of forest betel extracts of 0
g/l, 20 g/l, 40 g/l, 60 g/l, 80 g/l, and 100 g/l. 3) Lastly, in order to test the effective
frequency of spraying forest betel’s leaf against snails, CRD with 4 treatments
and 4 replications to obtain 16 experimental units were applied. The treatment
was without spraying; the forest betel leaf extract frequency was 1 × 1 week, 1 ×
2 weeks, and 1 × 3 weeks.
Forest betel’s leaves were the best treatment, causing 40-60% total
mortality with an initial death time of 6,4-8,8 hours after application and a lethal
time of 50 at 21-46.4 hours after application. Forest betel leaf extract at 100 g/l
concentration had the highest mortality (68.75%) with an initial death time of 11
hours after application, lethal time 50 of 34.5 hours after application, and LC50
8,23% LC95 29,52%. Spraying forest betel extract once a week was the best
treatment because it caused 100% mortality with an initial time of death of 18,75
hours after application, a lethal time 50 191,25 hours after application, and
4,35% attack intensity.
