Abstract
Abstract. This research was conducted to increase the yield and quality of corn through the application of inorganic fertilizers, and the utilization of corn for noodles that support food security. This research was carried out in two stages, the first stage was to determine the effectiveness of NPK 26-12-12 fertilizer on the yields and quality of corn. Corn with the best quality obtained from the best treatment of fertilization results at the first stage, is used as raw material in the second stage- namely noodles production. Corn is processed into corn flour, then corn flour is used as an ingredient for noodle production. Noodles are very popular in the community as an alternative to staple foods other than rice, so corn noodles can support food security through the use of local food. The second stage is to determine the quality of noodles with corn raw materials derived from the best treatment of fertilization results at the first stage. The factors that were used in the first stage were the combination dose of NPK 26-12-12 + urea + KCl which was compared to NPK 15-15-15 + urea + KCl (there are nine treatments, three replications). The factors that were used in the second stage was the percentage of corn flour (0- 10- 20- 30- 40- 50- 60%) to make noodle (three replications). The results of the first research found that the application of NPK fertilizers can increase the vegetative growth of corn plants, the results of observations of the components of corn yields that are most effective in increasing corn crop production, there is a G treatment with a value of RAE 181 which produces a corn harvest weight of 6.94 t/ha and the R/C ratio value of 1.56. The results of the second research found that the addition of corn flour affected the physical, chemical, and organoleptic properties. Panelists like noodles with the addition of 30% corn flour. In this treatment, the protein value was 3.697%- fat of 4.407- water content of 63.383%- ash content of 0.837%, and carbohydrate of 27.677%. The panelist^s preference for the color of corn noodles was 4.625, the aroma of 4.562- the textures of 4.500- the taste of 4.562- and the general preference of 4.437.
