An addition of bentonite as absorbent mineral to the pelletizing process of hatchery waste was expected able to improve and maintain physical-organoleptic quality of pellet product during storage. The experiment was conducted by completely randomized design with factorial pattern 2 x 3 and 3 replications of each combination. The factors were addition of bentonites (0 and 3%) and time lenght of storage (4, 8 and 12 weeks). Parameters observed were organoleptic quality (texture, color, odour and the pellets rupture) and physical quality (durability and hardness). Organoleptic quality evaluations were performed by 15 trained panelists. Data were analyzed by the KruskalWallis Test α 0.05, while durability and hardness by the analysis of variance. The results showed that there was no interaction effect between bentonites addition and storage time to the physical organoleptic quality of pellet product. The organoleptic qualities of pellet did not change during storage. Pellet Durability Index (PDI) and hardness of pellets remained high (> 90% and 5 kg/cm). However, pellet with addition of 3% bentonite have lower hardness than pellet without the addition of bentonite. It was concluded that 3% bentonite addition and time of storage up to 12 weeks did not affect the physical-organoleptic quality of hatchery waste pellets.Key Words: Hatchery Waste Pelleted, Bentonite, Storage, Physical-Organoleptic, Quality ABSTRAKPenambahan bentonit sebagai mineral absorben pada proses pembuatan pelet limbah penetasan diharapkan mampu meningkatkan dan mempertahankan mutu fisik-organoleptik pelet selama penyimpanan. Penelitian dilakukan menggunakan RAL faktorial 2×3 sebanyak 3 ulangan untuk masing-masing kombinasi perlakuan. Perlakuan yang diberikan adalah penambahan bentonit (0 dan 3%) dan lama penyimpanan (4, 8 dan 12 minggu). Parameter yang diamati adalah mutu organoleptik (tekstur, warna, bau dan jumlah pelet pecah) dan mutu fisik (durabilitas dan hardness). Evaluasi mutu organoleptik dilakukan oleh 15 panelis terlatih. Data diuji KruskalWallis α 0,05 sementara durabilitas dan hardness diuji menggunakan analisis ragam. Hasil penelitian menunjukkan bahwa tidak ada pengaruh interaksi antara penambahan bentonit dan waktu penyimpanan terhadap mutu fisik organoleptik. Mutu organoleptik tidak mengalami perubahan selama penyimpanan baik dengan bentonit atau tanpa bentonit. Nilai durabilitas (PDI) dan hardness pelet tergolong tinggi (>90% dan 5 kg/cm) selama penyimpanan. Namun, pelet dengan penambahan 3% bentonit memiliki nilai hardness yang lebih rendah dibandingkan dengan pelet tanpa penambahan bentonit. Hal ini dapat disimpulkan bahwa penambahan bentonit hingga 3% dan lama penyimpanan hingga 12 minggu tidak mempengaruhi mutu fisik-organoleptik pelet limbah penetasan.
