Abstract

Abstract—Main problem in the processing of Dioscorea alata’s tuber into flour is the changing of colour. One factor in color changing is attributed to antocyanin reaction in the tuber. Several methods can be applied to minimise the browning and hence maintain the natural colour preferred by the consumers. This research was conducted to obtain the combination of age of harvest, blanching temperature and blanching length which produce the highest content of antocyanin in Dioscorea alata’s flour. The responses measured was anthocyanin content. The result showed that age of harvest was the main factor for anthocyanin content of Dioscorea alata flour. The optimum anthocyanin content is predicted to be achieved by using tuber harvested at 9.6 months, temperature of blanching 86.12oC and blanching time for 0.56 menit.

Abstract

Family Medicinal Plants (TOGA) is a type of plant of choice which is very useful as medicine with easy maintenance and relatively low cost. So that TOGA is an alternative to family medicine by means of processing and production that is simple and safe because it rarely causes side effects, is easy to process and can be consumed for first aid in cases of minor illnesses such as fever, cough, or to help maintain stamina. The existence of TOGA is very easy to find around community housing that has a plot of land or on a plantation. However, there are still many people who are not aware that these plants can be used as medicinal plants. The service is carried out in Lengkese Village, Takalar Regency, where geographically the majority of the population earns crops and farms. In addition, this village has plants that can be grown into family medicinal plants. The method used to carry out this service includes observation and data collection as well as planting of family medicinal plants available in the village. The result is the availability of land or family medicinal plant plantations that can be managed and utilized by the local community.
