<![CDATA[ABSTRAK Bekatul beras merah merupakan produk samping dari proses penggilingan padi beras merah yang potensial dijadikan sebagai pakan penguat. Penelitian bertujuan untuk mengetahui pengaruh lama penyimpanan terhadap sifat fisik bekatul beras merah. Penelitian dilakukan secara eksperimental menggunakan rancangan acak lengkap. Data yang dihasilkan diuji menggunakan analisis ragam dan jika ada perbedaan yang nyata maka dilanjutkan dengan uji Jarak Berganda Duncan. Penelitian terdiri dari 5 perlakuan berupa lama penyimpanan yaittu 0, 1, 2, 3, 4 pekan. Masing-masing perlakuan diulang sebanyak 5 kali. Pengujian yang dilakukan adalah kadar air, kerapatan tumpukan, kerapatan pemadatan tumpukan, kerapatan pemadatan tumpukan metode banting, berat jenis, dan sifat organoleptik. Hasil menunjukkan bahwa lama penyimpanan nyata (P<0,05) meningkatkan kadar air, menurunkan nilai kerapatan tumpukan, kerapatan pemadatan tumpukan, kerapatan pemadatan tumpukan metode banting, tetapi tidak memengaruhi (P>0,05) berat jenis. Perubahan warna terjadi pada pekan keempat, perubahan bau mulai terjadi pada pekan ketiga, perubahan tekstur dengan adanya gumpalan pada pekan ketiga, serangan serangga pada pekan keempat, tetapi tidak terdeteksi adanya jamur yang terlihat secara kasat mata hingga pekan keempat. Kesimpulan, lama penyimpanan dapat menyebabkan perubahan sifat fisik dan organoleptik bekatul beras merah.Kata kunci: bekatul beras merah, penyimpanan, sifat fisik ABSTRACT Brown rice polish is a by-product from brown rice grinding which is potential to be used as concentrate feed. This research was aimed to find out the effect of storage duration on physical properties of brown rice polish. This research used experimental of Completely Randomized Design (CRD). Data collected was analyzed using analysis of variance and continued by Duncan’s test if the results was significant. This research contained 5 treatments storage duration which are 0, 1, 2, 3, and 4 weeks. Each treatment was replicated by 5 times. The properties tested were water content, bulk density, compacted bulk density, thrown compacted bulk density, specific gravity, and organoleptic properties. The result showed that storage duration was significantly (P<0.05) increased water content, decrease bulk density, compacted bulk density, thrown compacted bulk density while specific gravity was not affected (P>0.05). The color was changed in the fourth week, the scent was changed in in the third week, the texture shown by clotting occur in the third week, presence of insect in the fourth week while there was no presence of fungus seen even in the fourth week. It is concluded that storage duration changed the physical and organoleptic properties of brown rice polish.
