Abstract


Konsorsium Azotobacter A1b, A3, A6, A9, dan A10 digunakan sebagai agen pengomposan bentuk curah yang mempunyai makronutrien tersedia berbentuk nitrat, fosfat, dan kalium. Tujuan dari penelitian adalah membentuk biofertilizer curah menjadi biofertilizer granul. Untuk membentuk granul digunakan bahan perekat tepung tapioka, tanah liat, dan gum arabika masing-masing sebesar 5%. Analisis kadar air dan waktu dispersi diujikan untuk mengetahui keefektifan bahan perekat

Biofertilizer berbentuk granul dengan bahan perekat tepung tapioka mempunyai waktu dispersi lebih cepat sehingga lebih efektif digunakan dibandingkan tanah liat dan gum arabika. Setelah pengeringan bahan perekat tepung tapioka mempunyai kadar air tertinggi 20,6 %.
