This research was conducted on field experiments of agriculture faculty of university field area located in road of no.1 field of estate. The study was conducted from April to July 2017. Using factorial randomized block design (RAK) with three replications. The first factor tested was the concentration of liquid organic fertilizer of cow urine waste ie U0 = without POC, U1 = 2% consentation (20 ml POC / liter of water), U2 = 4% concentration (40 ml POC / liter of water), U3 = 6% 6% concentration (60 ml POC / liter of water). The second factor is the dose of coffee skin compost that is K0 = without coffee skin compost, K1 = 10 ton / Ha, K2 = 20 ton / Ha, K3 = 30 ton / Ha. The results showed that the application of liquid organic fertilizer of cow urine wastes with U3 treatment = 6% has a real effect on the number of leaves, length of cob, the production of perfot and on the application of coffee skin compost significantly influence treatment K1 = 10 Ton / Ha and the effect on the height of sweet corn crop In general, this study showed a real effect on sweet corn and best gift of POC combination of cow urine waste at 6% concentration and coffee skin compost at dose of 10 Ton / Ha
