Abstract
Kailan (Brassica oleraceae var. alboglabra) merupakan jenis sayuran daun yang paling banyak dikonsumsi, sehingga permintaan produksi kailan terus meningkat setiap tahun. Dalam upaya meningkatkan produktivitas kailan maka dilakukan pengaplikasian komposit ekstrak batang brotowali dan bionutrien S-367B sebagai suplemen tanaman. Penelitian ini dilakukan untuk mengetahui pengaruh komposit biopestisida ekstrak batang brotowali dan bionutrien S-367B terhadap pertumbuhan, laju pertumbuhan, dan hasil panen kailan. Metode penelitian ini meliputi tahap ekstraksi batang brotowali kering dengan maserasi, aplikasi komposit biopestisida ekstrak batang brotowali dan bionutrien S-367B 25%, 50%, dan 75% pada tanaman perlakuan, pengamatan pertumbuhan tinggi tanaman, panjang daun, lebar daun, dan masa hasil panen kailan, serta menganalisis dan mengkarakterisasi ekstrak batang brotowali dengan metode skrining fitokimia, spektrofotometer UV-Vis, dan spektrofotometer FTIR. Hasil penelitian menunjukkan bahwa ada pertumbuhan tinggi tanaman, panjang daun, dan laju pertumbuhan tertinggi tanaman kailan dicapai oleh komposit biopestisida ekstrak batang brotowali dan bionutrien S-367B 25% dengan dosis 7,5 mL/L secara berurutan yaitu 34,60 cm; 22,27 cm; dan 0,325 minggu-1, serta lebar daun tertinggi 23,20 cm yang dicapai oleh komposit biopestisida ekstrak batang brotowali dan bionutrien S-367B 50% dengan dosis 10 mL/L. Pada kontrol pelarut diperoleh pertumbuhan tinggi tanaman, panjang daun, laju pertumbuhan, dan lebar daun secara berurutan 32,33 cm; 17,17 cm; 0,3172 minggu-1; dan 16,67 cm. Rata-rata massa hasil panen tertinggi dihasilkan oleh komposit biopestisida ekstrak batang brotowali dan bionutrien S-367B 25% dengan dosis 7,5 mL/L 336,67 g dibandingkan kontrol pelarut sebesar 114,67 g. Hasil analisis ekstrak etanol batang brotowali mengandung total fenolik sebesar 10,12 ± 0,01 mg GAE/g ekstrak dan hasil karakterisasi ekstrak etanol batang brotowali menunjukkan senyawa aktif yang terkandung di dalamnya merupakan senyawa fenolik dan nonfenolik.
Kailan (Brassica oleraceae var. alboglabra) is the most widely consumed leaf vegetable, so the demand for kailan production continues to increase every year. In an effort to increase the productivity of kailan, the application of a composite of brotowali stem extract and S-367B bionutrients as a plant supplement was carried out. This study was conducted to determine the effect of the composite of brotowali stem extract biopesticide and S-367B bionutrients on the growth, growth rate, and harvest of kailan. The research method includes the stage of extracting dry brotowali stems by maceration, application of a composite of brotowali stem extract biopesticide and S-367B bionutrients 25%, 50%, and 75% on treatment plants, observation of plant height growth, leaf length, leaf width, and harvest period of kailan, as well as analyzing and characterizing the brotowali stem extract using the phytochemical screening method, UV-Vis spectrophotometer, and FTIR spectrophotometer. The results showed that there was the highest growth of plant height, leaf length, and growth rate of kale plants achieved by the composite of biopesticide of brotowali stem extract and bionutrient S-367B 25% with a dose of 7.5 mL/L sequentially, namely 34.60 cm; 22.27 cm; and 0.325 week-1, and the highest leaf width of 23.20 cm achieved by the composite of biopesticide of brotowali stem extract and bionutrient S-367B 50% with a dose of 10 mL/L. In the solvent control, the growth of plant height, leaf length, growth rate, and leaf width were obtained sequentially 32.33 cm; 17.17 cm; 0.3172 week-1; and 16.67 cm. The highest average mass of harvest was produced by the composite of biopesticide of brotowali stem extract and bionutrient S-367B 25% with a dose of 7.5 mL/L 336.67 g compared to the solvent control of 114.67 g. The results of the analysis of the ethanol extract of the brotowali stem contained a total of phenolics of 10.12 ± 0.01 mg GAE/g extract and the results of the characterization of the ethanol extract of the brotowali stem showed that the active compounds contained in it were phenolic and nonphenolic compounds.
