Amonia adalah gas hasil penguraian bahan limbah nitrogen dalam manur, seperti asam amino, uric acid, protein yang tidak diserap dan senyawa non protein nitrogen (NPN) lainnya akibat adanya aktivitas mikroorganisme dalam manur. Larva BSF diketahui mampu mengurai limbah organik, termasuk limbah kotoran ternak. Penelitian ini bertujuan mengetahui efektifitas larva BSF dalam mengurangi kadar gas amonia yang dihasilkan dari manur ayam. Penelitian ini menggunakan rancangan acak lengkap faktorial. Faktor pertama penambahan larva BSF sebanyak 0 larva (P0), 40 larva(P1), 60 larva(P2), dan 90 larva (P3) pada 1 Kg manur ayam . Sedangkan perlakuan kedua adalah waktu pengamatan yaitu pada hari ke 0, 1, 2, 3, 4, 5, 6, dan 7. Setiap unit perlakuan diulang 3 kali. Rata-rata kadar gas amonia manur ayam pada perlakuan P0 (Kontrol) pada hari ke 0 sampai 7 masing-masing adalah 8,56 ppm, 7,83 ppm, 6,8 ppm, 5,8 ppm, 5,53 ppm, 4,8 ppm, 4,53 ppm dan 3, 76 ppm sedangkan pada perlakuan P3 (90) larva pada hari ke 0 sampai 7 masing-masing adalah 7,76 ppm, 6,26 ppm, 4,73 ppm, 3,43 ppm, 3,03 ppm, 2,5 ppm, 1,6 ppm dan 1 ppm. Berdasarkan analisis statistik menunjukkan bahwa jumlah larva BSF, waktu pengamatan dan interaksi antar perlakuan berpengaruh nyata (P

Ammonia is a gas resulting from the decomposition of nitrogenous waste materials in manures, such as amino acids, uric acid, unabsorbed proteins and other non-protein nitrogenous compounds (NPN) due to the activity of microorganisms in manures. BSF larvae are known to be able to decompose organic waste, including livestock manure. This study aims to determine the effectiveness of BSF larvae in reducing ammonia gas levels produced from chicken manure. This study used a factorial complete randomized design. The first factor was the addition of BSF larvae as many as 0 larvae (P0), 40 larvae (P1), 60 larvae (P2), and 90 larvae (P3) in 1 kg of chicken manur. While the second treatment is the time of observation, namely on days 0, 1, 2, 3, 4, 5, 6, and 7. Each treatment unit was repeated 3 times. The average ammonia gas levels in chicken manur in treatment P0 (Control) on days 0 to 7 were 8.56 ppm, 7.83 ppm, 6.8 ppm, 5.8 ppm, 5.53 ppm, 4,8 ppm, 4.53 ppm and 3.76 ppm while in treatment P3 (90) the larvae on days 0 to 7 were 7.76 ppm, 6.26 ppm, 4.73 ppm, 3.43 ppm respectively , 3.03 ppm, 2.5 ppm, 1.6 ppm and 1 ppm. Based on statistical analysis, it showed that the number of BSF larvae, observation time and interactions between treatments had a significant effect (P
