ABSTRAK Bunga kol (Brassica Olerecae var. botrytis) memiliki kandungan gizi tinggi yang bermanfaat bagi kesehatan namun penggunaan pupuk kimia anorganik diharapkan dapat dikurangi dengan pupuk yang lebih ramah lingkungan. Bionutrien S-367B dengan dosis 5 mL/L diaplikasikan pada tanaman bunga kol. Tujuan penelitian ini untuk mengetahui pengaruh bionutrien S-367B terhadap kondisi tanah, pertumbuhan dan hasil panen serta kandungan gizi bunga kol. Tahapan penelitian ini yaitu analisis dan karakterisasi bionutrien S-367B meliputi analisis kadar NPK, kadar air serta karakterisasi menggunakan FTIR, tahap pengamatan pertumbuhan meliputi tinggi tanaman, panjang dan lebar daun, serta jumlah stomata daun, massa panen, penentuan kadar vitamin C dengan titrasi iodometri dan penentuan kadar protein dengan metode kjeldhal. Hasil penelitian menunjukkan bionutrien S-367B mengandung 0,08% N, 0,0082% P, dan 0,0117% K, kadar air sebanyak 97, 27% dan terdapat gugus fungsi - OH, C≡C, C=C, COO, C-H aromatik, C-H fenil, dan cincin benzena. Aplikasi bionutrien S-367B dapat menstabilkan pH dan kelembaban tanah. Pada pertumbuhan tinggi tanaman, panjang dan lebar daun bunga kol rata - rata diperoleh oleh kelompok kontrol positif secara berurutan yaitu 30,31 cm; 19,78 cm; 12,41 cm, sedangkan jumlah stomata daun tertinggi diperoleh kelompok perlakuan bionutrien S-367B senilai 19,33. Massa hasil panen tertinggi diperoleh kelompok kontrol positif yaitu 27,09 Kg, bionutrien S-367B meningkatkan kandungan vitamin C yaitu sebesar 22,18 mg/100 g, sedangkan kandungan protein bunga kol perlakuan dan kontrol positif bernilai sama yaitu 2,7%. Berdasarkan uji signifikansi diperoleh pH dan kelembaban tanah, tinggi tanaman, panjang dan lebar daun, massa panen tidak memiliki perbedaan nyata.

Bionutrient S-367B with a dose of 5 mL/L was applied to cauliflower plants. The purpose of this study was to determine the effect of bionutrient S-367B on soil conditions, caulilfower plant growth, mass yields and nutrition content. Stages of research include analysis of NPK content, water content and characterization using FTIR of bionutrient S-367B, The observation of plants involve height growth, leaf length and width, number of leaf stomata, mass yield, vitamin C content using iodometric titration and protein content using kjeldhal method. The results showed that bionutrient S-367B contained of 0.08% N, 0.0082% P, and 0.0117% K, 97.27% of water and functional groups - OH, C≡C, C=C, COO, C-H aromatic, C-H phenyl, and benzene ring. Bionutrient S-367B applications can stabilize soil pH and moisture. Cauliflower plant height growth, leaf length and width obtained by positive control groups with an average 30.31 cm; 19.78 cm; 12.41 cm, while the highest number of leaf stomata obtained by treatment group obtained 19.33. Cauliflower highest yield mass obtained by the positive control group is 27.09 kg. In addition bionutrient S-367B increases the vitamin C content by 22.18 mg/100g, while the protein content of treatment and positive control group are equal to 2.7%. Based on the significance test, pH and soil moisture, plant height, leaf length and width, crop yield, did not have significant differences.
