Abstract

This study aims to determine the best level of administration of dragon fruit stem waste on the quality of cow feces compost. The design used was a completely randomized design (CRD) with 5 treatments and 4 replications. The treatments consisted of P0 = cow feces 97.5% + EM4 2.5%, P1 = cow feces 77.5% + dragon fruit stem waste 20% + EM4 2.5%, P2 = cow feces 67.5% + waste dragon fruit stem 30% + EM4 2.5%, P3 = cow feces 57.5% + dragon fruit stem waste 40% + EM4 2.5, P4 = cow feces 47.5% + dragon fruit stem waste 50% + EM4 2.5%. The observed variables were color, odor, texture, temperature, pH, nitrogen, carbon, phosphorus, potassium and C/N ratio. The results showed that the colors produced in the treatment were P0 (100% black), P1 (100% black), P2 (100% black), P3 (50% black chocolate and 50% brown), P4 (100% chocolate). The odor produced in the treatment of P0 (100% soil), P1 (75% soil and 25% weathered), P2 (50% weathered and 50% weathered), P3 (100% weathered), P4 (100% weathered). The resulting texture in the treatment of P0 (100% crumb), P1 (100% crumb), P2 (100% crumb), P3 (50% crumb and 50% coarse), P4 (75% coarse and 25% crumb), pH value in treatment P0 (7.23%). The addition of dragon fruit stem waste had a very significant effect (P<0.01) on the content of nitrogen, phosphorus, potassium and C/N. The highest nitrogen content was at P2 (1.60%) and the lowest was at P0 (1.31%), the highest phosphorus content was at P4 (0.31%) and the lowest was at P0 (0.18%), the highest potassium content was found in at P3 (1.16%) and the lowest at P0 (0.44%), the highest C/N content was at P0 (22.25%) and the lowest was at P3 (16.75%). Meanwhile, the carbon content had no significant effect (P>0.05). From the results of this study, it can be concluded that the best compost quality results were obtained in treatment (P3), on the content of carbon, potassium and C/N. Because it is based on the standard range of compost quality (SNI 19-7030-2004).
