Abstract

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.

Abstract

Changing a habit is not an easy job, let alone that has great risks as they relate to social and cultural issues. In understanding of technological innovation requires mental readiness to take the decision to adopt it through a process of perception, because the rate of adoption of an innovation depends on the perceptual characteristics of the adopter of innovation that includes the company telnologi relative advantage, the level of conformance level of complexity, can be tried and can be observed. The purpose of this study to examine the relationship between the characteristics of the farmers, the communication behavior and support efforts by the perception of farmers to use organic fertilizer on crops mendong. Partially, the data were analyzed using Spearman Rank analysis, while simultaneously using Kendall concordance coefficient W. Analysis Research was conducted in February-November 2016 using the method of survey. Sampling using simple random sampling against rushes farmers in Sub Manonjaya with a total sample of 30 farmers.The results showed the internal characteristics of the farmers, support the business climate as well as the perception of farmers on organic farming fertilization mendong included in the medium category and communication behavior are included in the low category. Simultaneously there is a relationship between the internal characteristics of the farmers, the communication behavior and support the business climate by perception of farmers on the use of organic fertilizer to the level of the relationship is very close. Partially that have a relationship with the perception of the use of organic fertilizers is the communication behavior and the support of the business climate. Guidance to the farmers both individually and institutionally still needs to be done to encourage farmers to use organic fertilizer on farm mendong.
