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

Indonesia is one of the countries with the fourth largest natural wealth in the world. The magnitude of the natural potential provides a great opportunity for scientists to develop it as a useful product for society. One of the medicinal plants that can be used is lime (C. aurantifolia). The purpose of this study was to determine the inhibition of lime peel extract (Citrus aurantifolia) against Bacillus cereus, Escherichia coli and mold bacteria using the coloni counter method. This research includes the extraction process of the maceration method then the extract obtained is tested for bacterial analysis using a colony counter. Based on the results of the research conducted, it can be concluded that lime peel extract (C. aurantifolia) has the ability to inhibit the growth of B. cereus and E.coli bacteria, respectively 0 APM/g and <3.0 APM/g. This is because there are bioactive compounds such as -pinene and D-limonene in lime peel extract (C. aurantifolia).
