Abstract
Penelitian ini bertujuan untuk menganalisis pengaruh substitusi tepung oatmeal pada tortilla chips terhadap kualitas fisik dan daya terima konsumen. Penelitian dilakukan di Laboratorium Pengolahan Makanan, Program Studi Pendidikan Tata Boga, Fakultas Teknik, Universitas Negeri Jakarta yang dimulai pada bulan September 2022 hingga Juni 2024. Penelitian ini menggunakan metode eksperimen dengan sampel tortilla chips substitusi tepung oatmeal sebanyak 15%, 25% dan 35%. Pengujian kualitas fisik diuji terhadap dua aspek yaitu, ketebalan dan kekerasan yang dilakukan dengan uji Anova menghasilkan bahwa terdapat perbedaan yang signifikan terhadap ketiga produk tortilla chips sehingga dilanjutkan dengan uji Duncan yang menunjukkan bahwa terdapat perbedaan nyata pada aspek ketebalan pada persentase 15% dan aspek kekerasan pada persentase 35%. Pengujian daya terima konsumen diuji kepada 75 panelis konsumen dengan uji Friedman yang menunjukkan bahwa aspek warna dan aroma oatmeal tidak terdapat pengaruh signifikan, sedangkan pada aspek aroma jagung, rasa gurih, rasa jagung, rasa oatmeal dan tekstur terdapat pengaruh signifikan sehingga dilanjutkan dengan uji Tuckey. Hasil uji Tuckey menunjukkan bahwa terdapat perbedaan nyata pada aspek aroma jagung, rasa gurih, rasa jagung, rasa oatmeal dan tekstur pada persentase 35%. Hasil penelitian ini menunjukkan bahwa produk perlakuan terbaik adalah tortilla chips substitusi tepung oatmeal sebesar 35% yang memiliki tekstur dan ketebalan sesuai dengan tortilla chips dan produk yang paling disukai oleh konsumen. ***** This research aims to analyze the effect of substitution of oatmeal flour for tortilla chips on physical quality and consumer acceptance. The research was conducted at the Food Processing Laboratory, Culinary Education Study Program, Faculty of Engineering, Jakarta State University starting from September 2022 to June 2024. This research used an experimental method with samples of tortilla chips substituted with 15%, 25% and 35% oatmeal flour. Physical quality testing was tested on two aspects, thickness and hardness, which was carried out using the Anova test resulting in a significant difference in all three tortilla chip products, so it was continued with the Duncan test which showed that there was a real difference in the thickness and hardness aspect respectively at a percentage of 15% and 35%. The consumer acceptability test was tested on 75 consumer panelists using the Friedman test which showed that the color and aroma aspects of oatmeal had no significant influence, while the aspects of corn aroma, savory taste, corn taste, oatmeal taste and texture had a significant influence so it was continued with the Tuckey test. The Tuckey test results show that there are real differences in the aspects of corn aroma, savory taste, corn taste, oatmeal taste and texture at a percentage of 35%. The results of this research show that the best treatment product is tortilla chips with a 35% substitution of oatmeal flour which has a texture and thickness similar to tortilla chips and is the product most liked by consumers.
