Quality starch noodles within analysis: water content, ash content, protein content, fat content, crude fiber content, and organoleptic (texture, taste, color, and aroma (smell)). The best results were obtained in the T1R1 treatment which got rank 1 with water content 33.38%, ash content 2.05%, protein content 8.31%, fiber content 12.92%, fat content 1.22%, organoleptic aroma 2.94 with aroma value "Quite tasty", organoleptic texture 3.76 with a value of "springy", color organoleptic 3.73 which is "attractive", organoleptic taste 3.76 that is "delicious".
