Abstract
Penelitian ini bertujuan untuk menganalisis pengaruh substitusi tepung oatmeal pada pembuatan roti tawar open top terhadap daya terima konsumen yang meliputi aspek volume, warna kulit luar, kerak roti, karakter kulit, remah / pori-pori, aroma,warna bagian dalam, rasa dan tekstur. Penelitian ini menggunakan metode eksperimen yang dilakukan di Laboratorium Pastry dan Bakery, Program Studi Tata Boga, Fakultas Teknik, Universitas Negeri Jakarta pada bulan April 2021 hingga Desember 2021. Uji organoleptik dilakukan pada 30 orang panelis agak terlatih. Hasil dari deskriptif data menunjukkan bahwa roti tawar substitusi tepung oatmeal sebanyak 10% adalah yang paling disukai oleh konsumen pada semua aspek, dengan rata-rata untuk aspek volume 4,43; aspek warna bagian luar 4,13; aspek kerak roti 3,96; aspek karakter kulit 3,97; aspek remah/ pori-pori 3,90; aspek aroma 4,10; aspek warna bagian dalam 4,17; aspek rasa 4,40 dan aspek tekstur 4,17 dimana pada semua aspek menunjukkan berada pada rentangan kategori suka hingga sangat suka. Pengujian hipotesis menggunakan uji Friedman dengan taraf signifikansi α = 0,05 dan dilanjutkan dengan uji Tuckeys menunjukkan bahwa pengunaan tepung oatmeal dengan substitusi sebesar 10%, 20%, dan 30% berpengaruh nyata pada semua aspek yaitu aspek volume, warna bagian luar, kerak roti, karakter kulit, remah/pori-pori, aroma, warna bagian dalam, rasa, dan tekstur remah terhadap daya terima konsumen roti tawar, dengan formula yang paling disukai substitusi sebesar 10%. This study aims to analyze the effect of substitution of oatmeal flour on the manufacture of open top loaf bread on consumer acceptance which includes aspects of volume, outer skin color, bread crust, skin character, crumb / pores, aroma, inner color, taste and texture. This study uses an experimental method conducted at the Pastry and Bakery Laboratory, Catering Study Program, Faculty of Engineering, Jakarta State University from April 2021 to December 2021. Organoleptic tests were carried out on 30 moderately trained panelists. The results of the descriptive data show that 10% of plain bread substituted with oatmeal flour is the most preferred by consumers in all aspects, with an average volume aspect of 4.43; outer color aspect 4.13; bread crust aspect 3.96; skin character aspect 3.97; crumb aspect/pores 3.90; aroma aspect 4.10; inner color aspect 4.17; the taste aspect is 4.40 and the texture aspect is 4.17 where in all aspects it shows that they are in the like to very like category. Hypothesis testing using the Friedman test with a significance level of = 0.05 and continued with the Tuckeys test showed that the use of oatmeal flour with substitutions of 10%, 20%, and 30% had a significant effect on all aspects, namely the volume aspect, outer color, bread crust. , skin character, crumbs/pores, aroma, inner color, taste, and crumb texture on consumer acceptance of loaf bread, with the most preferred formula being substituted by 10%.
