Abstract

Abstrak. Kue nastar suweg merupakan produk hasil percobaan dengan menggunakan tepung suweg sebagai bahan subtitusi tepung terigu. Tepung suweg merupakan hasil olah dari umbi suweg (Amorphophallus campanulatus B1) yang kurang dikenal dan dimanfaatkan oleh masyarakat karena memiliki rasa gatal yang disebabkan oleh kandungan oksalat dan dapat dihilangkan dengan proses pencucian dan perendaman dalam larutan garam. Dalam rangka mencapai tujuan penelitian, maka dilakukan eksperimen 2 faktor yang disusun secara faktorial yaitu subtitusi tepung terigu:tepung suweg 40:60, 50:50 dan 60:40, dengan suhu pembakaran 1600C, 1800C dan 2000C dalam pembuatan kue nastar suweg. Dari uji Anova menunjukkan bahwa subtitusi tepung terigu:tepung suweg berpengaruh nyata terhadap warna, dan tidak berpengaruh terhadap rasa, aroma, keremahan dan tingkat kesukaan. Suhu pembakaran berpengaruh sangat nyata terhadap warna, rasa, aroma dan tingkat kesukaan, dan tidak berpengaruh terhadap keremahan kue nastar suweg.    Hasil uji kimia menunjukkan bahwa kadar air terendah diperoleh dari perlakuan subtitusi tepung 50:50 dengan suhu pembakaran 1800C. Kandungan abu, protein kasar, serat kasar, Ca, kalori tertinggi dihasilkan dari subtitusi tepung 50:50 dengan suhu pembakaran 1800C. Kandungan lemak kasar tertinggi diperoleh dari perlakuan 60:40 dengan suhu 1600C.  Sedangkan kandungan karbohidrat tertinggi yaitu perlakuan subtitusi tepung 60:40 dengan suhu pembakaran 1800C. Dari hasil uji organoleptik dan uji kimia, hasil yang terbaik diperoleh dari perlakuan subtitusi tepung 50:50 dengan suhu pembakaran 1800C.
