Umi Saroh Astriningtyas, - (2024) KOMPOSIT BIOPESTISIDA EKSTRAK DAUN SIRIH (Piper betle L.) DENGAN BIONUTRIEN S-367B DITERAPKAN PADA TANAMAN KAILAN (Brassica oleracea var. alboglabra). S1 thesis, Universitas Pendidikan Indonesia.
Abstract
Budidaya tanaman kailan (Brassica oleracea var. alboglabra) tidak lepas dari penggunaan pestisida sintetis untuk mengendalikan hama dan penyakit. Alternatif yang lebih aman yaitu menggunakan petisida nabati atau biopestisida, salah satunya adalah daun sirih (Piper betle L.). Daun sirih mengandung senyawa antibakteri, antijamur dan sebagai larvasida. Peningkatan pertumbuhan dan hasil panen tanaman kailan membutuhkan nutrisi tambahan berupa suplemen yang disebut bionutrien. Tujuan penelitian ini untuk mengetahui karakterisasi ekstrak daun sirih serta pengaruh aplikasi komposit ekstrak daun sirih dan bionutrien S-367B terhadap pertumbuhan, laju pertumbuhan dan hasil panen tanaman kailan. Metode yang digunakan yaitu ekstraksi daun sirih, aplikasi komposit ekstrak daun sirih dan bionutrien S-367B 25%, 50% dan 75% dosis 5 mL/L, 7,5 mL/L, 10 mL/L dengan pengamatan terhadap tinggi tanaman, panjang daun, lebar daun dan hasil panen tanaman kailan. Selain itu juga skrining fitokimia senyawa alkaloid, flavonoid, saponin dan tanin, penetapan kadar total fenol dengan spektrofotometer UV-Vis serta karakterisasi gugus fungsi ekstrak daun sirih dengan spektrofotometer FTIR. Hasil penelitian menunjukkan ekstrak daun sirih positif mengandung senyawa alkaloid, flavonoid, saponin dan tanin. Kadar total fenol ekstrak daun sirih sebesar 437,70 mg ± 0,08 mg GAE/g. Pada karakterisasi gugus fungsi didapatkan bahwa ekstrak daun sirih mengandung senyawa turunan fenol dan bukan fenol. Pertumbuhan tanaman kailan dengan perlakuan 25% dosis 5 mL/L dinilai paling efektif dengan rata-rata tinggi tanaman sebesar 44,33 cm, panjang daun sebesar 20,83 cm, dan lebar daun sebesar 20,00 cm. Laju pertumbuhan tertinggi diperoleh kelompok perlakuan 50% dosis 7,5 mL/L yaitu 0,3318 minggu-1 dibandingkan kelompok kontrol pelarut yaitu 0,3159 minggu-1. Massa hasil panen tanaman kailan terbesar diperoleh oleh kelompok perlakuan 50% dosis 5 mL dengan massa panen rata-rata sebesar 267,33 ± 67,28 gram dibandingkan dengan kelompok kontrol pelarut sebesar 114,67 ± 7,57 gram. Cultivation of kailan (Brassica oleracea var. alboglabra) cannot be separated from the use of synthetic pesticides to control pests and diseases. A safer alternative is to use natural pesticides or biopesticides, one of which is betel leaf (Piper betle L.). Betel leaves contain antibacterial, antifungal and larvicidal compounds. Increasing the growth and yield of kailan plants requires additional nutrients in the form of supplements called bionutrients. The purpose of this study was to determine the characterization of betel leaf extract and the effect of composite application of betel leaf extract and bionutrient S-367B on the growth, growth rate and yield of kailan plants. The methods used were betel leaf extraction, application of betel leaf extract composite and bionutrient S-367B 25%, 50% and 75% doses of 5 mL/L, 7.5 mL/L, 10 mL/L with observation of plant height, leaf length, leaf width and yield of kailan plants. In addition, phytochemical screening of alkaloid, flavonoid, saponin and tannin compounds, determination of total phenol content with UV-Vis spectrophotometer and characterization of functional groups of betel leaf extract with FTIR spectrophotometer. The results showed that betel leaf extract positively contained alkaloid, flavonoid, saponin and tannin compounds. The total phenol content of betel leaf extract was 437.70 mg ± 0.08 mg GAE/g. In the characterization of functional groups, it was found that betel leaf extract contained phenol and non-phenol derivative compounds. The growth of kailan plants with 25% treatment dose of 5 mL/L was considered the most effective with an average plant height of 44.33 cm, leaf length of 20.83 cm, and leaf width of 20.00 cm. The highest growth rate was obtained by the 50% treatment group at a dose of 7.5 mL/L, which was 0.3318 week-1 compared to the solvent control group, which was 0.3159 week-1. The largest mass of kailan plant harvest was obtained by the 50% treatment group at a dose of 5 mL with an average harvest mass of 267.33 ± 67.28 grams compared to the solvent control group of 114.67 ± 7.57 grams.
