The experiment was conducted in teaching farm of State Polytechnic of Lampung from January 2016 until June 2016. The treatments arranged in Randomized Block Design (RBD) with the factorial pattern consisting of two factors. The first factor was the concentration of cow urine, consisting of four levels: 15 cc.l<sup>-1</sup>, 30 cc.l<sup>-1</sup>, 45 cc.l<sup>-1</sup> and 60 cc.l<sup>-1</sup>. The second factor was the duration of cow urine fermentation, consisting of five levels: 0 day, 7 day, 14 day, 21 day and 28 day.</em><em> Rubber seedlings were used as plant indicator</em><em>. Observations included plant height, number of petiole, stem diameter, </em><em>stem </em><em>girth, and dry weight of </em><em>biomass</em><em>. The results showed that the treatment of cow urine concentration had significant effect on plant height and number of petiole, but very significant effect on stem diameter, </em><em>stem </em><em>girth and dry weight of </em><em>biomass</em><em>. Likewise, the treatment of cow urine fermentation has significant effect on all observed variables except on the dry weight of </em><em>biomass</em><em> has a very significant effect. The interaction between treatment of cow urine concentration and cow urine fermentation did not significantly affect all variables except on dry weight of </em><em>biomass</em><em> had significant effect, i</em><em>.</em><em>e</em><em>.</em><em> cow urine concentration treatment of 45 cc.l<sup>-1</sup> and fermentation of cow urine for 28 days resulted in dry weight </em><em>of biomass</em><em> higher rubber seedlings</em><em>.  </em></p><p><em> </em></p><p><em>Keywords: cow urine, fermentation, rubber seedlings</em></p><p><em><em><em><em><em><em><em><em>Permalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/651</em></em></em></em></em></em></em></em></p> ER -
