Abstract

Tujuan penelitian adalah untuk mengetahui karakteristik fisik, kimia dan sensoris beras tiruan berbasis tepung singkong yang telah diberi perlakuan fermentasi menggunakan Bacillus amyloliquefaciens dan Trichoderma viride. Penelitian dilakukan di Laboratorium Kimia Hasil Pertanian, dan Mikrobiologi Hasil Pertanian Jurusan Teknologi Pertanian Fakultas Pertanian, Universitas Sriwijaya Indralaya pada bulan Mei 2012 sampai dengan Januari 2013. Penelitian menggunakan Rancangan Acak Lengkap Faktorial (RALF) dengan dua faktor perlakuan dan tiga ulangan. Faktor perlakuan yang diamati adalah jenis mikroorganisme (J i: Bacillus amyloliquefaciens, J2: Trichoderma viride) dan konsentrasi mikroorganisme (Pj: 1%, P2: 5%, P3: 10%). Parameter yang diamati meliputi warna, suhu gelatinisasi, waktu gelatinisasi, kadar air, kadar abu, kadar serat kasar, kadar serat pangan larut, kadar protein, populasi mikroorganisme, uji organoleptik (kesukaan) terhadap rasa, aroma, tekstur dan warna, serta uji mutu hedonik terhadap tekstur. Hasil penelitian menunjukkan bahwa jenis mikroorganisme berpengaruh nyata terhadap kadar air dan kadar serat kasar. Konsentrasi mikroorganisme berpengaruh nyata terhadap waktu gelatinisasi, kadar air, dan kadar serat kasar. Interaksi jenis dan konsentrasi mikroorganisme berpengaruh nyata terhadap kadar air, kadar serat kasar beras tiruan. Beras tiruan dengan perlakuan JjPj (kultur Bacillus amyloliquefaciens dan konsentrasi 1%) merupakan perlakuan terbaik berdasarkan uji sensoris, karakteristik fisik dan kimia. Beras tiruan dengan perlakuan JjPi mempunyai kadar air 9,01%, lightness 79,77%, chroma 5,37%, dan hue 86,77%, suhu gelatinisasi 73°, waktu gelatinisasi 3,67 menit, kadar abu 3,07%, kadar serat kasar 5,88%, kadar serat larut 4,51%, protein 4,83%, sensoris (warna, aroma, rasa, tekstur) yang disukai dan mutu tekstur yang pulen.
