Abstract

Pengendalian hama merupakan faktor penting dalam budidaya tanaman. Penggunaan biopestisida menjadi salah satu alternatif dalam mengendalikan hama pada tanaman. Tanaman tembakau berpotensi sebagai biopestisida karena mengandung senyawa aktif yang mampu membasmi hama. Penelitian ini bertujuan untuk mengetahui pengaruh komposit biopestisida ekstrak daun tembakau (Nicotiana tabacum L.) dan bionutrien S-367B yang diterapkan pada tanaman kailan (Brassica oleracea var. alboglabra) terhadap pertumbuhan, laju pertumbuhan, dan hasil panen pada kailan. Tahapan penelitian meliputi ekstraksi daun kering tembakau dengan metode maserasi, tahap aplikasi komposit biopestisida dan bionutrien S-367B 25%, 50%, dan 75% pada kailan, tahap pengamatan pertumbuhan dan hasil panen kailan, serta karakterisasi ekstrak daun tembakau. Hasil penelitian menunjukkan bahwa kandungan pada ekstrak daun tembakau terdiri atas senyawa alkaloid, flavonoid, saponin, dan tanin dengan kadar total fenol sebesar 171,33 ± 0,01 mg GAE/g. Hasil penelitian terhadap pertumbuhan tinggi tanaman, panjang daun, dan lebar daun tanaman kailan tertinggi diperoleh oleh perlakuan campuran biopestisida 25% dosis 5 mL/L secara berurutan, yaitu 49,0 cm; 22,7 cm; dan 20,7 cm. Sedangkan, Laju pertumbuhan tanaman yang paling cepat diperoleh oleh perlakuan komposit ekstrak daun tembakau dan bionutrien S-367B 75% dosis 5 mL/L sebesar 3423 minggu-1. Massa hasil panen paling unggul diperoleh perlakuan komposit 50% 7,5 mL dengan rata-rata 350,00 ± 12,0d gram.

Pest control is an important factor in crop cultivation. The use of biopesticides is one alternative in controlling pests in plants. Tobacco plants have the potential as biopesticides because they contain active compounds that can eradicate pests. This study aims to determine the effect of a biopesticide composite of tobacco leaf extract (Nicotiana tabacum L.) and bionutrient S-367B applied to kailan (Brassica oleracea var. alboglabra) plants on growth, growth rate, and yield on kailan. The research stages include extraction of dried tobacco leaves by maceration method, application stage of biopesticide composite and bionutrient S-367B 25%, 50%, and 75% on kailan, observation stage of growth and yield of kailan, and characterization of tobacco leaf extract. The results showed that the content of tobacco leaf extract consisted of alkaloid, flavonoid, saponin, and tannin compounds with total phenol content of 171.33 ± 0.01 mg GAE/g. The results of research on the growth of plant height, leaf length, and leaf width of the highest kailan plants were obtained by the treatment of 25% biopesticide mixture at a dose of 5 mL/L in sequence, namely 49.0 cm; 22.7 cm; and 20.7 cm. Meanwhile, the fastest plant growth rate was obtained by the composite treatment of tobacco leaf extract and bionutrient S-367B 75% at a dose of 5 mL/L at 3423 weeks-1. The most superior harvest mass was obtained by the 50% composite treatment of 7.5 mL with an average of 350.00 ± 12.0d grams.
