Abstrak. Penelitian tentang keefektifan beberapa serbuk nabati sebagai
bioinsektisida terhadap hama Sitophilus zeamais Motsch. Pada jagung di
penyimpanan, telah dilakukan di Laboratorium Hama Tumbuhan Fakultas
Pertanian Universitas Syiah kuala Darussalam Banda aceh. Penelitian ini dimulai
dari mulai Mei 2015 sampai Desember 2016. Penelitian ini bertujuan untuk
mendapatkan jenis serbuk nabati yang lebih efektif dalam mengendalikan
kumbang bubuk pada jagung di penyimpan. Rancangan yang digunakan dalam
penelitian ini adalah rancangan acak lengkap pola Non faktorial dengan 4
perlakuan dan diulang 6 kali ulangan yaitu Perlakuan serbuk lada hitam, lada
putih, cabai rawit dan serai wangi. Peubah yang diamati meliputi Mortalitas
imago, Jumlah imago turunan pertama (F1), persentase kerusakan jagung, ratarata

waktu imago muncul, daya repelensi. Hasil penelitian pada pengamatan 4
HSA menunjukan bahwa Mortalitas imago tertinggi pada perlakuan lada hitam
yaitu 18,33% dan jumlah imago turunan pertama pada pengamatan 34 HSA
tertiggi dijumpai pada perlakuan cabai rawit yaitu 53,33% . Selanjutnya rata-rata
persentase kerusakan biji jagung pada pengamatan 68 HSA tertinggi dijumpai
pada perlakuan serai wangi yaitu 18,00% dan lama imago S. zeamais muncul pada
pengamatan 34 HSA tertinggi dijumpai pada perlakuan lada hitam yaitu 34,17%.
Daya repelensi pada pengamatan 2 JSA tertinggi dijumpai pada perlakuan lada
hitam yaitu 58,33%.
Kata kunci : Serbuk Nabati, Piper nigrum, Cymbopogon nardus L., Cafsicum
frutescans, Mortalitas, Persentase imago muncul, daya repelensi.

Abstract. Research on the effectiveness of some vegetable powders as
bioinsecticides to pests Sitophilus zeamais Motsch. In maize in storage, it has
been done in Plant Hama Laboratory of Agricultural Faculty of Shia University of
kuala Darussalam Banda aceh. This research starts from May 2015 to December
2016. This research aims to get more effective type of vegetable powder in
controlling powder beetle on corn in storage. The design used in this study was a
complete randomized design of Non Factorial with 4 treatments and repeated 6
times repetition of black pepper treatment, white pepper, cayenne pepper and
citronella. The observed variables include imago mortality, first-generation imago
amount (F1), percentage of maize damage, average imago time emerging,
repelensi power. The result of the research on observation of 4 HSA showed that
the highest imago mortality in black pepper treatment was 18.33% and the
number of first derivative imago on observation of 34 HSA was found in the
treatment of cayenne pepper 53.33%. Furthermore, the average percentage of
maize damage on observation of 68 highest HSA was found in the treatment of
citronella that is 18.00% and the duration of imago S. zeamais appeared on the
2
*
highest 34 HSA observations found in black pepper treatment that was 34.17%.
The highest reproduction capacity in JSA 2 observation was found in black pepper
treatment which was 58.33%.


Keywords: Vegetable Powder, Piper nigrum, Cymbopogon nardus L, Cafsiccum
