This study aimed toanalyze the level of panelist preference for color , flavor and texture of sweet potato rollscake. This study used a variation of the treatment formulations flour and sweet potato withthree treatments, ie comparison of sweet potato flour : wheat flour 750 grams : 250 grams; 500 grams : 500 grams ; 250 grams : 750 grams . Parameters measured were panelistspreference level of the color, flavor and texture . The results showed that the sweet potatoflour rolls in like most consumers is the formulation of sweet potato flour 500 grams and500 grams of wheat flour .Keywords : rolls cake , flour , sweet potato flour

Abstract

Indonesia  is  the  number  two  country  's  that  produce  of  natural  rubber  in  the  world  after Thailand. The main drawback of natural rubber when compared to synthetic rubber is in the consistency of its quality. The aim of this research is to determine the effect of coagulant agent : alum, acetic acid and TSP ( Triple Super Phosphate ) on the ash content and the value of plasticity retention index ( PRI ) of SIR 20 ( Standard Indonesian Rubber ). Research conducted two (2 ) stages, namely the stage of processing rubber SIR 20 with latex base material. Clots made with latex coagulant treatment variations, which alum, acetic acid and TSP. Once formed rubber SIR 20, then analyzed ash content and value analysis PRI. The experimental design used was a factorial design experiment with a single factor, namely the type of coagulant consisting of a 20 % solution of TSP, 20 % alum solution and 20 % acetic acid solution with three times repetition of treatment, if there is a real difference, then tested further by DMRT. The results showed that the use of acetic acid coagulant and alum produce rubber SIR 20 with ash content and PRI value that meets  the standards set by SNI 06-1903-2000, whereas  coagulant TSP produce rubber SIR 20 with PRI values that are in accordance with standard, but the ash content above the standards set by the SNI.Keywords : latex, coagulant, SIR 20
