Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh substitusi tepung ubi cilembu (Ipomoea batatas var. Cilembu) pada pembuatan chiffon cake terhadap karakteristik fisik dan daya terima konsumen. Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) satu faktor, yaitu persentase substitusi tepung ubi cilembu terhadap tepung terigu. Perlakuan yang digunakan terdiri atas tiga variasi substitusi, yaitu 10%, 20%, dan 30%. Pengujian karakteristik fisik meliputi daya kembang, baking loss, dan porositas, sedangkan pengujian daya terima konsumen dilakukan melalui uji hedonik terhadap aspek warna luar, warna dalam, rasa manis, rasa ubi cilembu, aroma ubi cilembu, tekstur kelembutan, dan tekstur berpori. Panelis yang digunakan dalam penelitian ini berjumlah 30 orang panelis agak terlatih. Data karakteristik fisik dianalisis menggunakan uji ANOVA dan uji lanjut Duncan, sedangkan data daya terima konsumen dianalisis menggunakan uji Friedman dan uji lanjut Tukey. Hasil penelitian menunjukkan bahwa substitusi tepung ubi Cilembu memberikan pengaruh nyata terhadap karakteristik fisik (daya kembang, baking loss, dan porositas) dan daya terima konsumen (warna, rasa, aroma, dan tekstur) chiffon cake. Perlakuan substitusi tepung ubi cilembu menghasilkan perbedaan tingkat kesukaan panelis pada aspek warna, rasa, aroma, dan tekstur. Berdasarkan hasil uji daya terima, dapat disimpulkan bahwa chiffon cake dengan substitusi tepung ubi cilembu 10% dapat diterima oleh konsumen dan berpotensi menjadi alternatif produk cake berbasis pangan lokal. ***** This study aimed to determine the effect of Cilembu sweet potato flour (Ipomoea batatas var. Cilembu) substitution on the physical characteristics and consumer acceptance of chiffon cake. The experiment employed a Completely Randomized Design (CRD) with one factor, namely the percentage of Cilembu sweet potato flour substitution for wheat flour, consisting of three treatments: 10%, 20%, and 30%. Physical characteristics analyzed included cake volume, baking loss, and porosity, while consumer acceptance was evaluated using a hedonic test on external color, internal color, sweetness, Cilembu flavor, Cilembu aroma, and texture attributes of softness and porosity, involving 30 semi-trained panelists. Physical data were analyzed using ANOVA and Duncan post hoc test, and consumer acceptance data were analyzed using the Friedman test and Tukey's post hoc test. The results indicated that substituting Cilembu sweet potato flour significantly affected both the physical characteristics and consumer acceptance of the chiffon cake. Chiffon cake with 10% Cilembu flour substitution was accepted by consumers and has potential as an alternative cake product based on local ingredients.
