Limbah Rumah Potong Hewan (RPH) berpotensi digunakan sebagai pupuk organik. Teknologi yang dapat direkomendasikan untuk pemanfaatan limbah Rumah Potong Hewan adalah pengomposan. Penelitian bertujuan untuk mengkaji pengaruh pupuk organik limbah RPH terhadap kesuburan tanah dan produktivitas padi. Penelitian dilaksanakan di kebun percobaan Fakultas Pertanian Universitas Siliwangi Tasikmalaya dari Mei sampai September 2017.  Percobaan menggunakan Rancangan acak kelompok 10 taraf perlakuan diulang 3 kali. Perlakuan kombinasi dosis N,P, K dan pupuk organik (PO), yaitu: A= Dosis N,P,K; B= dosis N,P,K + 2,5 t ha -1 PO; C=Dosis N,P,K + 5 t ha -1 PO; D= Dosis N,P,K + 7,5 t ha -1 PO; E= ¾ dosis N,P,K   + 2,5 t ha -1 PO; F= ¾ dosis N,P,K + 5,0 t ha -1 PO; G= ¾ dosis N,P,K + 7,5 t ha -1 PO; H= ½ dosis N,P,K + 2,5 t ha -1 PO; I= ½ dosis N,P,K + 5,0 t ha -1 PO;  J= ½ dosis N,P,K + 7,5 t ha -1 PO. Dosis rekomendasi N, P dan K:  urea 300  kg ha -1 , SP 36 150  kg ha -1 , dan KCl 100 kg ha -1 . Hasil penelitian menunjukkan bahwa aplikasi pupuk organik 2,5 t ha -1 dan ¾ dosis N, P dan K menghasilkan gabah lebih tinggi dan meningkatkan kesuburan tanah. Slaughterhouse waste is potential to be used as organic fertilizer. The technology recommended for the usage of slaughterhouse waste is composting. This research was aimed to study effect of organic fertilizer slaughterhouse waste on soil fertility and rice productivity. The research was conducted in the experiment site of Agricultural Faculty, Universitas Siliwangi Tasikmalaya from May to September 2017. Randomized block design was used with ten level treatments and replicated three times. The treatment was combination dosage N,P, K and organic fertilizer (OF), namely : A= (N,P,K recommendation dose), B= (N,P,K dose + 2.5 t ha -1 OF), C= (N,P,K dose + 5 t ha -1 OF), D= (N,P,K dose + 7.5 t ha -1 OF), E= (3/4 dose of N,P,K + 2.5 t ha -1 OF), F= (3/4 dose of N,P,K + 5 t ha -1 OF), G= (3/4 dose of N,P,K + 7.5 t ha -1 OF), H=(1/2 dose of N,P,K + 2.5 t ha -1 OF), I= (1/2 dose of N,P,K + 5 t ha -1 OF), J= ( ½ dose of N,P,K + 7.5 t ha -1 OF). The recommendation dose of N, P and K, respectively: urea 300 kg ha -1 , SP 36 150 kg ha -1 , and KCl 100 kg ha -1 . The results showed application organic fertilizer 2,5 t ha -1 dan ¾ dose of N, P, K fertilizer increased yields grain higher and improve soil fertility.
