Abstract

Pengendalian hama dan penyakit pada budidaya tanaman brokoli (Brassica oleracea var. italica) masih dilakukan dengan menggunakan pestisida sintesis. Salah satu alternatif lain adalah penggunaan biopestisida dari bahan alam. Daun noni (Morinda citrifolia L.) telah diteliti berpotensi sebagai bahan baku biopestisida ramah lingkungan, karena daunnya mengandung senyawa kimia aktif seperti flavonoid, alkaloid, steroid, terpenoid, kuinon, saponin, dan tanin yang bersifat toksik bagi serangga. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi komposit biopestisida daun noni (Morinda citrifolia L.) dengan bionutrien S-367B terhadap panjang daun, lebar daun, tinggi tanaman, dan laju pertumbuhan tanaman brokoli (Brassica oleracea var. italica.). tahapan penelitian ini meliputi tahap ekstraksi daun noni (Morinda citrifolia L.), tahap uji fitokimia, uji total fenolik, dan karakterisasi gugus funsi menggunakan metode spektrofotometri FTIR, tahap aplikasi komposit biopestisida ekstrak daun noni (Morinda citrifolia L.) dan bionutrien S-367B dengan variasi konsentrasi 25%, 50%, dan 75% dan dosis (5 mL/L; 7,5 mL/L; dan 10 mL/L) dalam 1000 mL air, tahap pengamatan pertumbuhan dan hasil panen tanaman brokoli (Brassica oleracea var. italica). Hasil karakterisasi dari ekstrak daun noni (Morinda citrifolia L.) menunjukan adanya senyawa alkaloid, flavonoid, saponin, dan tanin yang diperkuat dengan hasil analisis FTIR, serta kadar total fenol sebesar 12,15 mg GAE/1 g sampel. Hasil penelitian menunjukan bahwa pada pertumbuhan panjang daun, lebar daun, tinggi tanmaan, dan laju pertumbuhan diperoleh pada kelompok perlakuan komposit biopestisida daun noni (Morinda citrifolia L.) dengan bionutrien S-367B 50% dosis 10 mL/L secara berturut-turut yaitu 36,0 cm; 23,7 cm; 37,3 cm; dan 0,5450 minggu-1 dibandingkan dengan kelompok kontrol secara berturut-turut yaitu 32,0 cm; 17,3 cm; 24,7 cm; dan 0,4437 minggu-1. Massa hasil panen tanaman brokoli (Brassica oleracea var. italica.) tertinggi diperoleh pada kelompok perlakuan komposit biopestisida daun noni (Morinda citrifolia L.) dengan bionutrien S-367B 50% dosis 10 mL/L yaitu 1.0012,00 ± 34,3 gram dibandingkan dengan kelompok kontrol sebesar 515,00 ± 87,6 gram. Pest and disease control in broccoli (Brassica oleracea var. italica) cultivation is still largely carried out using synthetic pesticides. One alternative is the use of biopesticides derived from natural materials. Noni leaves (Morinda citrifolia L.) have been studied for their potential as eco-friendly biopesticide raw materials, as they contain bioactive compounds such as flavonoids, alkaloids, steroids, terpenoids, quinones, saponins, and tannins, which are toxic to insects. This study aimed to determine the effects of applying a composite biopesticide made from noni leaf extract (Morinda citrifolia L.) combined with S-367B bionutrients on leaf length, leaf width, plant height, and growth rate of broccoli (Brassica oleracea var. italica). The research stages included extraction of noni leaves (Morinda citrifolia L.), phytochemical tests, total phenolic content analysis, functional group characterization using FTIR spectrophotometry, and application of the composite biopesticide with S-367B bionutrients at varying concentrations (25%, 50%, and 75%) and doses (5 mL/L, 7.5 mL/L, and 10 mL/L) in 1000 mL of water, followed by observation of broccoli growth and yield. Characterization of the noni leaf extract revealed the presence of alkaloids, flavonoids, saponins, and tannins, confirmed by FTIR analysis, with a total phenolic content of 12.15 mg GAE/g sample. The results showed that the treatment group using a composite biopesticide of noni leaf extract (Morinda citrifolia L.) with S-367B bionutrients at 50% concentration and a dose of 10 mL/L yielded the highest growth performance in leaf length, leaf width, plant height, and growth rate, reaching 36.0 cm, 23.7 cm, 37.3 cm, and 0.5450 week⁻¹, respectively, compared to the control group with 32.0 cm, 17.3 cm, 24.7 cm, and 0.4437 week⁻¹, respectively. The highest broccoli yield was also obtained from the same treatment group, with an average mass of 1,012.00 ± 34.3 g, compared to the control group at 515.00 ± 87.6 g.
