Abstract

Preservation “siwalan” sap in Lamongan done in two ways, namely by the addition of lime solution and by addition of liquid of “tutup” flowers. “Tutup” flowers ((Macaranga tanarius (L.) Mull.Arg.) (name of Lamongan district) is included in the family Euphorbiaceae. Sugar is produced from the sap with liquid of “tutup” flowers preservative have better quality than the other sap preservative. The results also showed that the sap with liquid of “tutup” flowers preservative have a longer shelf life, with a fewer the number of total microbes. Therefore, it needs to be studied a potential “tutup” flowers extract as an anti‐microbial material. The purpose of this study is as follows: (1) to know and effectiveness test of “tutup” flowers pre‐ servative against pathogenic microorganisms and food destroyer, (2) to determine part of “tutup” plants which potentially as a preservative, and (3) to determine the minimum concentration of preservative with Contact Method. The results showed the following: (1) Growth of Saccharomyces cerevisiae and Staphylococcus aureus can be inhibited by liquid of “tutup” flowers, but the growth of Pseudomonas fluorecens are not inhibited by liquid of “tutup” flowers; (2) Pseudomonas fluorecens bacterial growth can be inhibited by a solution of lime, but the growth of Staphylococcus aureus and the Saccharomyces cereviseae not inhibited by a solu‐ tion of lime; (3) Inhibited the growth of Staphylococcus aureus by addition of “tutup” plant leaves extract with concentration 30 % and “tutup” plant flowers extract with 20% and 30% concentration, inhibited the growth of Pseudomonas fluorecens by addition of “tutup” plant leaves and flowers with 20% and 30% con‐ centration, whereas inhibited the growth of Saccharomyces cereviceae by the addition of leaf extract of “tutup” plant with a concentration of 20% and 30% and a flower extract of “tutup” plant with a minimum concentration of 10%; and (4) furthermore used flower extract of “tutup” plant with concentration of at least 20% can inhibited the growth of Staphylococcus aureus, Pseudomonas fluorecens, and Saccharomyces cereviceae. Key words: “tutup” flowers (Macaranga tanarius); antimicrobial; natural preservatives
