    Abstract

    Cookies is one of cake with it’s main ingredients is wheat flour. Until this moment, wheat flour requirement is fulfilled from importing. To reduce the increasing level of importing, it needs another alternative of food ingredients that can be used as a substitusion of wheat flour one of. Tuber alternatives that can be used to substitute wheat flour is cassava. Cassava is full of carbohydrate, but lack of proteins, so it needs addition of protein source. One of local protein source is wing bean seed. The research has two objectives. Firstly, in order to formulate how many percents of the cassava flour and of wing bean seed flour does result in the most preferable cookies by conducting organoleptical test including colour, aroma, texture, taste and overall. Secondly, in order to find out the effect on cassava flour and wing bean seed flour addition on cookies chemical properties including water, total protein, and ash levels. In order to achieve the objective, the substitution treatment of cassava and wing bean seed flour was conducted to the cookies preparation with the following formulation: formula I (100% wheat flour), formula II (70% wheat flour, 70% cassava), formula III (70% wheat flour, 25% cassava, 5% wing bean seed flour), formula IV (70% wheat flour, 20% cassava, 10% wing bean seed flour), and formula V (70% wheat flour, 15% cassava, 15% wing bean seed flour). Then, an analysis on chemical property was conducted including water level, ash and protein. Meanwhile organoleptical test on the panellist’s preference was conducted using scoring method with 25 untrained panellists. This research employed completely random design (RAL), each treatment consisting of 3 repetitions. Furthermore, the data was analysed statistically using ANOVA, when there was a significant difference, it would be followed by DMRT Test. The result of research shows that, the water, ash and protein levels increase with the addition of cassava flour and kecipir seed flour. Meanwhile the result of organoleptic test shows that the consumer’s acceptance level decreases with the addition of cassava flour and kecipir seed flour. The substitution of cassava flour 25% and kecipir seed flour is in fact still preferred and can be accepted well by the panellist. This kind of cookies formulation fulfils the SNI standard that is 4.725% water, 1.597% ash and 12.25% protein levels. Keywords: Cookies, cassava, wing bean seed
