| Judul Artikel | PENGARUH EKTRAK DAUN MIMBA (Azadirachta indica) TERHADAP PELETAKAN TELUR,PENETASAN TELUR, DAN PENOLAKAN MAKAN ULAT KROP KUBIS (Crocidolomia pavonana fab) DI LABORATORIUM |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui : 1) Pengaruh konsentrasi ekstrak daun nimba terhadap peletakan telur ulat krop kubis (C. pavonana). 2) Pengaruh konsentrasi ekstrak daun nimba terhadap penetasan telur ulat krop kubis (C. pavonana). 3) Pengaruh konsentrasi ekstrak daun nimba terhadap penolakan makan ulat krop kubis (C. pavonana). Penelitian ini dilaksanakan di Laboratorium Perlindungan Tanaman, Fakultas Pertanian, Universitas Jenderal Soedirman. Waktu penelitian dimulai dari bulan Januari hingga Maret 2018. Penelitian menggunakan rancangan Acak Kelompok (RAK). Penelitian terdiri dari lima perlakuan yaitu 1) tanpa perlakuan (kontrol), 2) Ektrak daun nimba konsentrasi 0,5%, 3) Ektrak daun nimba konsentrasi 1,0%, 4) Ektrak daun nimba konenstrasi 1,5%, 5) Ektrak daun nimba konsentrasi 2,0%. Variabel pengamatan meliputi jumlah kelompok telur yang diletakan,persentase kelompok telur yang menetas, berat daun kubis yang dimakan. Hasil penelitian menunjukkan bahwa Ektrak daun nimba konsentrasi 2% mampu menekan peletakan telur C.pavonana hingga 96,7%, Ektrak daun nimba konsetrasi 0,5% - 2% tidak mampu menekan penetasan telur C.pavonana, Ektrak daun nimba konsetrasi 0,5% - 2% tidak mampu menurunkan daya makan C.pavonana |
| Abtrak (Bhs. Inggris) | The attack of caterpillar pests (Crocidolomia pavonana Fab) on cabbage cultivation causes a high yield loss. Control using unwise chemical pesticides has a negative impact on the environment. So need to look for other alternatives that are more environmentally friendly, the use of neem leaves as a pesticide to be an alternative control of crop caterpillars are environmentally friendly. The Research aims to determine: 1). Effect of neem leaf extract concentration on laying of caterpillar eggs, 2). Effect of neem leaf extract concentration on egg hatching of cabbage head caterpillar (C. pavonana), 3). Effect of neem leaf extract concentration on the rejection of caterpillar meal (C. pavonana). The research was conducted at the Plant Protection Laboratory, Faculty of Agriculture, University of General Soedirman. This study started from January to March 2018. The study used Randomized Block Design . With treatment is a : A) without treatment (control), B) Neem leaf extract 0,5% concentration, C) Neem leaf extract 1.0% concentration, D) Neem ecstasy extract 1.5%, E) Neem leaf extract concentration 2.0%. Observational variables included the number of egg groups placed, the percentage of hatching eggs, and the weight of cabbage leaves eaten. The result of the research showed that the neem leaf extract of 2% concentration was able to suppress the laying of C. pavonana eggs up to 96,7% of neem leaf extract of 0,5% - 2% was not able to suppress the egg hatching of C. pavonana, the neem leaf extract of 0.5% - 2% are not able to reduce the power of eating C. pavonana. |
