Abstract

The objective of the research was to find out the optimum alkaline treatment to produce a light colour, starch-rich flour containing high levels of undamaged starch, intended for the making of a formulated biscuit. The research was divided into two experiments. First, a factorial randomized block design experiment with two factors: the concentration of NaOH (0.04%, 0.06%, and 0.08%) and the dipping time (15, 30 and 45 minutes). The second experiment was the use of the Linear Programming approach supported by the QSB to obtain the desirable biscuit formula. The results of the first experiment indicated that the breadfruit flour dipped for 45 minutes in the 0.08% NaOH solution was the best one. The treated flour at a moisture content of 6.63% contains 60.86% starch, 22.56% amylose, 3.25% protein, 6.26% fat, and the L value (degree of Lightness) of 74.9, water absorption index of 4.80 g/g, initiation of gelatinization temperature of 69.3 oC, gelatinization temperature of 80.9 oC, maximum viscosity of more than 2000 AU and undamaged granules. The best results of the second experiment was the biscuit formula containinq  31.76% breadfruit flour, 20% wheat flour, 13.03% red bean flour, which  meets  with  the  nutrition  requirement. The  texture  and  breaking force of the formulated biscuit was not significantly difference with the one of the biscuit made without the addition of breadfruit flour (the control), but has the lower L value. Moreover except  the crispness, the colour, aroma and the taste of formulated biscuit were found the best significantly different from those of the control biscuit.

Abstract

The objective of this research is to do a feasibility study with an emphasis on the financial aspect of the establishment of a middle scale industry if VCO as a primary product and biodiesel as a secondary product. The results indicated that the gross price for biodiesel is RP. 1754.43 and Rp. 7752.13 for VCO. BEP will be achieved at the production of 4655.3 liter of VCO and 2880.28 liter of biodiesel and a payback period of 11 months. The values of BC ratio, NPV and IRR were 4.71, Rp. 6680356346.00 and 259.24%, respectively and therefore the establishment of the industry was feasible. Keywords: VCO waste, biodiesel, feasibility study, industry
