Abstract

PENGARUH PUPUK KOTORAN AYAM TERHADAP PERTUMBUHAN DAN HASIL DUA VARIETAS JAGUNG DI LAHAN SULFAT MASAM Eva Fransiska1), Surachman2), Dwi Zulfita 2), Basuni2) 1) Mahasiswa Fakultas Pertanian dan 2) Dosen Fakultas Pertanian Universitas Tanjungpura Pontianak   ABSTRAK Penelitian ini bertujuan untuk mencari dosis pupuk kotoran ayam yang terbaik terhadap pertumbuhan dan hasil dua varietas jagung di lahan sulfat masam, mencari varietas jagung yang terbaik pertumbuhan dan hasil di lahan sulfat masam, mengetahui Interaksi antara pupuk kotoran ayam dan varietas jagung terhadap pertumbuhan dan hasilnya dilahan sulfat masam. Penelitian ini dilaksanakan di Desa Parit Canggek Kecamatan Sungai Kakap Kabupaten Kubu Raya Kalimantan Barat dari tanggal 8 Maret 2016 sampai 20 Juni 2016 dengan menggunakan metode eksperimen lapangan dalam bentuk rancangan Split Plot dengan 2 faktor. Faktor pertama adalah Pupuk Kotoran Ayam dengan 3 taraf yaitu: tanpa pemberian Pupuk kotoran Ayam (p0), 7,5 ton/ha (p1) dan 15 ton/ha (p2). Faktor kedua adalah Varietas Jagung yaitu : Varietas Sukmaraga (v1) dan varietas Bima 7 (v2). Hasil penelitian ini menunjukkan bahwa pemberian Pupuk Kotoran Ayam berpengaruh nyata terhadap tinggi tanaman pada umur 2, 3, 4, dan 5 MST, volume akar, luas daun, berat kering, panjang tongkol, diameter tongkol, berat biji pipil, berat tongkol per petak dan berat 1000 biji, berpengaruh tidak nyata terhadap jumlah klorofil daun. Perlakuan Jenis Varietas berpengaruh nyata terhadap tinggi tanaman pada umur 2,3, 4, dan 5 MST, berat kering tanaman, kadar klorofil daun, volume akar, berat biji pipil kering per tongkol, berpengaruh tidak nyata terhadap luas daun, panjang tongkol, diameter tongkol, berat tongkol per petak dan berat 1000 biji.   Kata kunci :Jenis Varietas, Lahan Sulfat Masam, Pupuk Kotoran Ayam

Abstract

Antioxidants are compounds that are able to ward off or reduce free radicals in the body so that they can prevent several diseases. Soursop leaves (Annona muricata L.) are used as a traditional herbal medicine to prevent or treat cancer, as well as a natural antioxidant, which is usually used by people by boiling it. The purpose of this study was to look at the phytochemical screening by comparing fresh boiled water, fresh juice, and a fresh extract of soursop leaves, as well as test the antioxidant activity with the addition of DPPH (1,1-diphenyl-2-picrylhydrazyl) and measured using a UV-Vis spectrophotometer at 516 nm. The results of the soursop leaf phytochemical screening showed that there were groups of chemical compounds such as flavonoids, glycosides, tannins, and saponins. The results of testing the antioxidant activity by looking at the maximum wavelength of DPPH, using a UV-Vis spectrophotometer, obtained IC50 values for fresh juice of 770.067 µg/mL, fresh decoction of 1,022.8422 µg/mL, and ethanol extract of 299.733 µg/mL. Based on the results of the study, it was shown that the ethanol extract had stronger antioxidant activity than a fresh decoction and the fresh juice of soursop leaves.
