PENGARUH TEPUNG DAUN SIRSAK (Annona muricata) TERHADAP MORTALITAS DAN PERKEMBANGAN KUMBANG Callosobruchus analis F. PADA BIJI KEDELAI DAN KACANG HIJAU

Abstract

Tujuan penelitian untuk mengetahui: (i) pengaruh tepung daun sirsak terhadap mortalitas dan
perkembangan Callosobruchus analis serta kerusakan dan penyusutan biji kedelai dan kacang hijau, dan (ii)
mendapatkan dosis tepung daun sirsak yang paling efektif untuk mengendalikan Callosobruchus analis pada biji
kedelai dan kacang hijau. Eksperimen menggunakan Rancangan Acak Lengkap pola faktorial. Perlakuan terdiri
atas kedelai (A) dan kacang hijau (B) dan dosis tepung daun sirsak yakni 1 g/100 g; 2 g/ 100 g; 3 g/ 100 g, dan
kontrol/tanpa perlakuan. Tiap Perlakuan diulang lima kali. Parameter yang diamati: persentase mortalitas
imago, jumlah telur yang diletakkan, jumlah telur yang menetas menjadi imago, persentase kerusakan biji, dan
persentase penyusutan bobot biji. Hasil penelitian menunjukkan bahwa tepung daun sirsak: (i) berpengaruh
terhadap mortalitas dan perkembangan C. analis pada biji kedelai dan kacang hijau, (ii) dapat mengurangi
terhadap kerusakan dan penyusutan bobot biji terhadap serangan C. analis. Namun demikian, belum didapatkan
dosis tepung daun sirsak yang efektif untuk mengendalikan kumbang C.analis. Tepung daun sirsak mulai dosis 2
g/100 g biji dapat menurunkan perkembangan kumbang C. analis, serta dapat mengurangi kerusakan dan
penyusutan bobot biji akibat kumbang C. analis saat di penyimpanan.
Kata kunci : tepung daun sirsak (Annona muricata); Callosobruchus analis F., kematian, perkembangan.

ABSTRACT
Objectives of this study were to know the effect of soursop leaf on mortality and development of
Callosobruchus analis F., and how damage and reduction on soybean and mungbean grains seed caused by C.
analis F, as well., and (to obatain the effective dosage of soursop leaf flour to control C. analis on soybean and
mungbean grains. The research was implemented experimentally by using complete randomized design (CRD),
by three replicates. Treatment was consisted of soybean and mungbean and the dosage of soursop leaf flour i.e. 1
g/100 g , 2 g/100 g, 3 g/100g, and control (without treatment). The observed variables were: the percentage of
the imago mortality, the percentages of seed damage, and the reduction of the seed weight. The result indicated
that: (i) the soursop leaf flour gave significant effect on mortality of C.analis on soybean and mungbean, and (ii)
reduced damage and decrease of the seed weightdue to C. anali. Unfortunatelly, the effective dosage of the
soursop leaf to control C.analis was not found yet. Flour leaf dosage 2 g/100 g seeds could decreased the
development of C.analis and reduced the percentage of the damage and seed weight loosed caused by humblebee
C.analis in the storage.
Key words: the flour of soursop leaf (Annona muricata); Callosobruchus analis F., mortality, development
