The purpose of this research is to determine a ratio of tapioca to sweet potato flour and the concentration of squid ink producing high quality kamaboko. The quality of kamaboko was assessed organoleptically, chemically and physically. Two-stage research method was conducted. Firstly, a preliminary research, analyzing amino acids in squid ink and determining the best formulation. Secondly, the main research using a randomized block design (RBD) consisting of 2 factors, namely factor P (comparison of tapioca with sweet potato flour and factor T (concentration of squid ink). The responses consisted of organoleptic response, chemical response, physical response and selected response.The P factor affected color, aroma, elasticity texture, water content, ash content and protein content. The T factor influenced color, taste, aroma, elasticity texture, water content, and protein content. The interaction of the two factors affected the elasticity and protein content. The selected sample was kamaboko made from equal weight of tapioca and sweet potato flour (P) added with 3% squid ink. The sample had a color value of 4.34, aroma 4.44, flavor 4, 19, resilience texture 4.40, water content 54.44%, ash content 1.66%, protein content 14.69%, hardness 4,363.25 g force, elasticity 32.32%, color test ΔL * (Light) +2.58, Δa * (+ red/-green) -2.38 and Δb * (+yellow/-blue) -2.28.
