POTENSI TUMBUHAN BERACUN SEBAGAI BAHAN BIOPESTISIDA DI CAGAR ALAM DOLOK SAUT
ABSTRACT: The very high use of
chemical pesticides in the agricultural sector is more alarming nowadays. The
negative impact of chemical pesticides are health problems in humans and damage
to the environment, so it is necessary to find the alternative to overcome this
problem. An alternative is by using biopesticides which utilizing poisonous
plants that exist in nature. The research is conducted in the Cagar Alam Dolok
Saut, Desa Pansur Natolu, Kecamatan Pangaribuan, Kabupaten Tapanuli Utara by
using purposive sampling method and shaped transect sample plots, with a total
of 98 plots. The purpose of this research is to identify the potential
poisonous plants as a biopesticide in conservation area of Dolok Saut. There
are 3 aspects of assessment that have been done; local knowledge aspect,
diversity aspect and phytochemical aspect. Result shows that there are 9 types
of poisonous plants that have been found: Apus Tutung (Clidemia hirta), Modang
lalisiak (Ficus sinuata Thunb), Sitanggis (Belamcanda sp.) Dong-dong (Laportea
stimulant Gaud) Antaladan (Xanthosoma sp.) Birah (Alocasia arifolia),
Tahul-tahul (Nepenthes mirabilis), Bedi-bedi (Callicarpa dichotoma) and Langge
(Homalomena javanica). All of samples are identified as having a potential to
be used as biopestisida ingredients because they contain secondary metabolites
alkoloid, saponins, tannins terpenes and flavonoids.
