Abstract

Abstrak. Telah dilakukan penelitian tentang pengaruh pengomposan terhadap rasio C/N kotoran ayam dan kadar hara NPK tersedia serta kapasitas tukar kation (KTK) tanah. Penelitian ini terdiri dari dua tahap yaitu: pertama mengetahui pengaruh pengomposan terhadap kadar C-organik, N-total, dan rasio C/N pupuk kandang ayam. Kedua mengetahui perubahan kadar NPK tersedia dan KTK tanah pupuk kandang ayam yang dicampur dengan tanah selama 8 minggu. Hasil penelitian menunjukkan pupuk kandang ayam hasil fermentasi EM4 memiliki kadar C-organik 17,4%; N-total 1,73%; dan rasio C/N 10. Rasio C/N yang didapatkan telah masuk dalam rentang standar yaitu 10-20. Pengukuran kadar hara NPK bentuk tersedia tertinggi didapatkan pada minggu ke-8. Kadar hara NPK tersedia berturut-turut adalah 10,7354 ppm; 164,6667 ppm; dan 235,1667 ppm. Masing-masing kadar masuk dalam kategori rendah, sangat tinggi, dan sedang. KTK tanah tertinggi ada pada minggu ke-8 yaitu 206,2899 meq/100gram.   Kata kunci: pengomposan, kotoran ayam, NPK tersedia, KTK tanah     Abstract. A studied about the composting effect of chicken manure towards C/N ratio and available NPK nutrient and soil cation exchange capacity (CEC) had been done. This studied consisted of two phases: first determine the effect of composting on levels of C-organic, N-total, and C / N ratio of chicken manure. The second were to know the changes of NPK available and soil CEC on chicken manure that mixed with soil for 8 weeks. The results showed chicken manure fermented using EM4 had 17,4% of C-organic; of 1,73% N-total; and 10 of C/N ratio. Its has been obtained in the standard range is 10-20. Measurement of levels of available NPK nutrients had higher levels obtained at eighth weeks is 10,7354 ppm; 164,6667 ppm; and 235,1667 ppm. Each level in the category of low, very high, and medium. Soil CEC had higher levels at eighth week is 206.2899 meq/100gram.   Keywords: composting, chicken manure, available NPK, soil CEC
