Abstract

Corn cobs are agricultural waste that is very widely available and has the potential to be developed as corn flour. This modified corn flour from corn cobs waste can be an alternative to flour in several flour-based processed products. The use of corn cobs, which so far has less economic value, is to conduct research to determine the quality content of corn flour and corn cobs, so it is necessary to characterize the quality of corn, especially microbial contamination based on the SNI standards that have been set.Methods: water content using gravimetric method, ash content using gravimetric method, microbial contamination test using ALT method of 25-250 colonies / gram counted and analysis of mold and E. coli bacteria. The results showed that the ash content was 0.0433%, 13.57% moisture content, 11.91% protein content, ALT 1.8 x 106, mold analysis of 4.3 x 102 cology / gram and analysis of E. coli bacteria amounting to 7.1 APM / g and B. subtilis amouting <1,0 x 102coloni/g.  So it can be concluded that corn cobs waste can be used as corn flour because it has fulfilled the SNI

Abstract

Moringa plants are one of the plants that contain lots of nutrients both minerals and vitamins. This study aims to determine the content of Vitamin C extract of Moringa oleifera Lam extract with different heights in Baubau. Moringa leaves were extracted by maceration using water and Sodium Oxalate (Na2C2O4) and vitamin C levels were analyzed using the UV-Vis Spectrophotometer Method. The results showed that the vitamin C content of Moringa leaves for a height of 20 masl (KP 20) in the coastal area was 0.59%, 50 masl (KM 50) 0.53%, while for an altitude of 296 masl (LBW) was 0.83% . From the data obtained shows that the highest levels of vitamin C are Moringa leaves located at a height of 296 mdl (LBW) compared to areas with low altitude in this case Moringa that grows on the coast (KP 20) and medium height (KM 50). From the results of this study it can be concluded that the vitamin C content of Moringa leaf extract which grows in the low area is 296.40 ppm, medium height 267,12 ppm and for the altitude region is 413.71 ppm.
