Efektivitas Penyemprotan Larutan EM4 (Effective Microorganism - 4) terhadap Penurunan Kadar Amonia pada Kandang Broiler Semi Closed House.
Abstract
Peningkatan kadar amonia dalam kandang broiler semi closed house dapat mempengaruhi kesehatan ternak ayam berupa gangguan saluran pernapasan pada ayam dan keresahan pada lingkungan sekitar perkandangan. Salah satu tindakan terhadap peningkatan kadar amonia dalam kandang dengan penyemprotan Effective Microorganisms - 4 (EM4). Laporan proyek akhir ini bertujuan untuk mendapatkan informasi pengaruh penyemprotan EM4 terhadap penurunan kadar amonia pada kandang ayam broiler semi closed house. Proyek ini dilakukan pada satu kandang ayam broiler yang memiliki populasi sebanyak 20.000 ekor. Pengambilan data kadar amonia dilakukan sebanyak 5 kali dengan menggunakan hydrion ammonia test paper selama 5 hari. Pengukuran kadar amonia dilakukan sebanyak 1 kali sebelum penyemprotan larutan EM4 dan 4 kali pengukuran kadar amonia setelah penyemprotan larutan EM4. Hasil penyemprotan larutan EM4 pada kandang broiler semi closed house menunjukkan adanya penurunan kadar amonia sebesar 5 ppm dalam kurun waktu 7 jam, penurunan kadar amonia sebesar 5 ppm bertahan sampai dengan 2 hari. Increasing ammonia levels in semi-closed house broiler cages can affect the health of chickens in the form of respiratory problems in chickens and anxiety in the environment around the cage. One action against increasing ammonia levels in the cage is spraying Effective Microorganisms - 4 (EM4). The purpose of this final project is to obtain information on the effect of EM4 spraying on reducing ammonia levels in semi-closed house broiler chicken cages. The project was carried out in a broiler chicken cage with a population of 20,000 birds. Data collection on ammonia levels was carried out 5 times using hydrion ammonia test paper for 5 days. Measurement of ammonia levels was carried out 1 time before spraying the EM4 solution and 4 times measurements of ammonia levels after spraying the EM4 solution. The results of spraying EM4 solution in semi-closed house broiler cages showed a decrease in ammonia levels of 5 ppm within 7 hours, a decrease in ammonia levels of 5 ppm lasted up to 2 days.
