Abstract

AbstrakPemanfaatan limbah organik dari perkebunan sebagai media tanam pakcoy (Brassica chinensis L.) diharapkan dapat ditingkatkan dengan penggunaan pupuk organik serta pupuk hayati. Penelitian disusun menggunakan Rancangan Acak Kelompok (RAK) pola faktorial. Faktor pertama adalah dosis asam humat meliputi 1, 3, dan 5 g. Faktor kedua adalah dosis Trichoderma sp., meliputi 50, 100, dan 150 mL. Data yang diperoleh kemudian dianalisis ragam pada taraf nyata 5%. apabila terdapat pengaruh nyata, dilanjutkan dengan uji DMRT. Hasil penelitian menunjukkan bahwa aplikasi asam humat dan Trichoderma sp. memiliki pengaruh mandiri dan tidak terdapat interaksi. Dosis asam humat 3 g per tanaman menghasilkan jumlah daun, panjang daun, tinggi tanaman, tinggi tanaman, bobot basah, dan bobot kering tanaman lebih tinggi dibanding dosis 1 dan 5 g. Perlakuan Trichoderma sp. dosis 50 mL per tanaman memiliki pengaruh lebih baik terhadap jumlah daun, panjang daun, tinggi tanaman, dan bobot basah tanaman.Kata Kunci: hortikultura, jamur, morfologi, senyawa organik Abstract The utilization of organic farm estate as pakcoy (Brassica chinensis L.) growing media may improved by using biofertilizer and organic fertilizer.

Abstract

Keong mas (Pomaceae canaliculata) merupakan organisme yang berkembang biak dengan cepat dan mampu merusak tanaman budidaya dalam kurun waktu yang singkat. Kandungan protein yang tinggi pada keong mas dapat digunakan sebagai pupuk cair dan berpotensi untuk meningkatkan kesuburan tanah dan pertumbuhan tanaman. Penelitian ini bertujuan untuk mengetahui kandungan asam amino pada pupuk organik cair keong mas yang diolah dengan metode fermentasi (POCMAS) dan mengevaluasi pemanfaatannya terhadap pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq.) di pembibitan awal. Penelitian ini dirancang menggunakan metode rancangan acak kelompok lengkap non faktorial (RAKL), yang terdiri dari empat perlakuan, yaitu PC00 (kontrol), PC11 (1 ml POCMAS/tanaman), PC15 (5 ml POCMAS/tanaman), PC10 (10 ml POCMAS/tanaman dengan 3 pengulangan. Hasil penelitian menunjukkan bahwa pemberian POCMAS berpengaruh nyata (P < 0,05) terhadap pertumbuhan tinggi tanaman, diameter batang dan luas daun pada 4 (empat) bulan setelah tanam (4 BST). Ketiga parameter tersebut menunjukkan nilai perbedaan nyata tertinggi berturut-turut, yaitu 28,14 cm; 9,26 cm dan 166,23 cm2 pada perlakukan pemberian POCMAS 10 ml/tanaman.  Hasil karakterisasi pupuk organik cair menunjukkan bahwa kandungan POCMAS memiliki 17 jenis asam amino dan 8 diantaranya adalah asam amino esensial, yaitu histidine, isoleusin, leusin, lisin, metionin, fenilalanin, treosin, dan valin. Potensi pengembangan pupuk asam amino dari oganisme pengganggu tanaman dengan metode fermentasi menjadi alternatif yang dapat digunakan dalam mengembangkan pupuk organik dalam mendukung pertanian organik.
