Aplikasi Pupuk Organik Cair Berbahan Baku Urin Ternak Terhadap Pertumbuhan Tanaman Pakcoy (Brassica rapa L.)

Abstrak Pupuk organik bentuk cair berbahan urin dari ternak adalah salah satu alternatif pupuk ramah lingkungan yang dapat meningkatkan produksi dan pertumbuhan pakcoy. Berdasarkan hal tersebut, peneliti terdorong melaksanakan kajian dengan tujuan mengetahui dampak pemberian pupuk organik cair berbahan urin ternak terhadap perkembangan tumbuhan pakcoy (Brassica rapa L.). Percobaan lima perlakuan memakai Rancangan Acak Lengkap (RAL) yang merupakan pemberian tipe pupuk organik cair hasil ternak urin kambing, urin sapi dan urin kelinci, pupuk kimia AB Mix sebagai pembanding dan tanpa pemupukan (kontrol). Pengamatan dilakukan terhadap tinggi tanaman, kuantitas daun, berat kering dan berat basah panen. Data  dianalisis menggunakan software SPSS serta diuji  Duncan Multiple Range Test (DMRT). Hasil kajian yaitu pada semua pupuk organik cair terjadi peningkatan kandungan unsur P, penurunan unsur K dan pH setelah difermentasi pH berkisar 6,85–8,45 dan sesuai dengan peraturan Menteri Pertanian No. 70/Permentan/SR.140/10/2011 tentang pupuk organik, pupuk hayati, dan pembenah tanah. Pupuk organik cair berbahan urin ternak mampu meningkatkan jumlah daun dan tinggi tanaman pakcoy yang secara sig nifikan berbeda dibandingkan pupuk kimia.  Aplikasi pupuk organik cair urin kambing menghasilkan berat kering dan berat basah panen pakcoy yang serupa dengan pupuk kimia.  AbstractLiquid organic fertilizer made from urine from livestock is an alternative to environmentally friendly fertilizers that can increase pakcoy production and growth. Based on this, researchers are interested in conducting research to determine the effect of liquid organic fertilizer made from livestock urine on the growth of pakcoy (Brassica rapa L.). The experiment was carried out with five treatments using a completely randomized design (CRD), namely the application of liquid organic fertilizer from goat urine, cow urine and rabbit urine, chemical fertilizer AB Mix as a comparison, and without fertilization (control). Observations were made on plant height, a number of leaves, dry weight and wet weight of harvest. Data were analyzed using SPSS software and further tested with Duncan Multiple Range Test (DMRT). The results of the study were that in all liquid organic fertilizers there was an increase in the content of P elements, a decrease in K elements, and pH after fermentation. 70/Permentan/SR.140/10/2011 concerning organic fertilizers, biological fertilizers, and soil enhancers. Liquid organic fertilizer made from livestock urine is able to increase the number of leaves and plant height of pakcoy which is significantly different from chemical fertilizers. The application of goat urine liquid organic fertilizer resulted in the same dry weight and wet weight of pakcoy harvest as chemical fertilizers.
