Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penambahan tepung ubi ungu pada pembuatan cone es krim terhadap daya terima konsumen. Penelitian dilakukan di laboratorium pengolahan Roti dan Kue Program Studi Pendidikan Tata Boga, Fakultas Teknik, Universitas Negeri Jakarta. Penelitian diawali dengan pembuatan tepung ubi ungu dengan waktu pengeringan 12 jam dengan suhu 400c-600c menggunakan oven. Pada penelitian ini penambahan tepung ubi ungu dapat digunakan dalam adonan cone es krim dengan persentase 20%, 30%, dan 40%. Penilaian uji daya terima konsumen dilakukan kepada 3 panelis ahli (Dosen Pendidikan Tata Boga), dan 30 panelis tidak terlatih untuk menilai cone es krim penambahan tepung ungu meliputi aspek warna, aroma, tekstur, dan rasa. Hasil yang diperoleh daril hasil uji validasi dengan rata-rata tertinggi pada aspek warna dengan nilai 3.7 berada pada kategori mendekati coklat agak keunguan, aroma dengan nilai 4.3 berada pada kategori beraroma ubi ungu, tekstur dengan nilai 4 berada pada kategori renyah, rasa ubi dengan nilai 4 berada pada kategori berasa ubi ungu, rasa manis dengan nilai 4 berada pada kategori terasa manis. Hasil uji organoleptik daya terima konsumen dengan rata-rata nilai tertinggi pada aspek warna dengan nilai 4,03 berada pada kategori suka, aroma dengan nilai 4,17 berada pada kategori suka, tekstur dengan nilai 4,17 berada pada kategori suka, rasa ubi dengan nilai 3,80 berada pada kategori mendekati suka, rasa manis dengan nilai 3,97 berada pada kategori mendekati suka. Hasil uji friedman menunjukkan tidak terdapat pengaruh penambahan tepung ubi ungu pada aspek warna, aroma, teksur, rasa ubi, rasa manis pada pembuatan cone es krim terhadap daya terima konsumen. Hasil uji fisik cone es krim penambahan tepung ubi ungu dengan perlakuan 20%, 30%, dan 40% memiliki waktu ketahanan terhadap es krim selama 120 menit hingga cone es krim memiliki tekstur yang lembek. Maka peneliti merekomendasikan penambahan tepung ubi ungu pada pembuatan cone es krim sebanyak 40%. ***** This research aims to analyze the effect of adding purple sweet potato flour to the manufacture of ice cream cones on consumer acceptance. The research was conducted at the Bread and Cake Processing Laboratory of the Catering Education Study Program, Faculty of Engineering, State University of Jakarta. The study began with the manufacture of purple sweet potato flour with a drying time of 12 hours at a temperature of 400 c-600 c using an oven. In this study, the addition of purple sweet potato flour can be used in ice cream cone dough with a percentage of 20%, 30%, and 40%. The assessment of the consumer acceptance test was carried out to 3 expert panelists (Lecturers of Catering Education), and 30 untrained panelists to assess the ice cream cone with the addition of purple flour covering aspects of color, aroma, texture, and taste. The results obtained from the validation test results with the highest average in the color aspect with a value of 3.7 are in the category close to purplish brown, the flavor with a value of 4.3 is in the purple sweet potato flavored category, texture with a value of 4 is in the crunchy category, sweet potato flavor with a value of 4 is in the purple sweet potato taste category, sweet taste with a value of 4 is in the sweet taste category. The results of the organoleptic test of consumer acceptance with the highest average value in the color aspect with a value of 4.03 are in the like category, flavor with a value of 4.17 are in the like category, texture with a value of 4.17 are in the like category, sweet potato taste with a value of 3.80 is in the category close to like, sweet taste with a value of 3.97 is in the category close to like. Friedman test results showed that there was no effect of adding purple sweet potato flour on aspects of color, flavor, texture, sweet potato taste, and sweetness in making ice cream cones on consumer acceptance. The results of the physical test of ice cream cones with the addition of purple sweet potato flour with 20%, 30%, and 40% treatments have a resistance time of 120 minutes to ice cream until the ice cream cone has a soft texture. The researchers recommend the addition of sweet flour in the manufactur of ice cream cone as much as 40%.
