PEMANFAATAN AIR REBUSAN UBI CILEMBU DAN UBI MERAH SEBAGAI MEDIA ALTERNATIF PERTUMBUHAN BAKTERI Staphylococcus aureus

Media is a material consisting of a mixture of nutrients used to grow microorganisms both in culturing bacteria, fungi, and other microorganisms. Utilization of natural resources such as several types of tubers that contain high enough carbohydrates has also been used as a medium for bacterial growth. Experimental Research, which aims to find out whether Staphylococcus aureus bacteria can grow on alternative media from the use of natural ingredients, namely boiled water sweet potatoes & red potatoes. Staphylococcus Aureus bacteria can be found in alternative media made from the use of boiled water for sweet potatoes and red potatoes. There are significant differences in bacterial growth in NA media and alternative media from sweet potatoes and red potatoes. The difference can be seen in NA media bacteria that grow to form large colonies, but in alternative media bacteria that grow like dots. In future studies, it is expected to add additional substances such as peptone as additional comparison ingredients. It is expected that future studies can conduct research by utilizing other parts of the yam plant as test material.
