Kandungan Total Fenol dan Aktivitas Antibakteri Kelopak Buah Rosela Merah dan Ungu Sebagai Kandidat Feed Additive Alami Pada Broiler
Abstract: Broiler
farming always use feed additives commercial to improve productivity of
broiler, but feed additives commercial have negative effect for consument. Feed
additive should have ability as an antibacterial. To minimize using commercial
feed additive we have to find alternatives to optimize the use of roselle
calyces. This experiment was conducted to knowing phenol content and
antibacterial activity of red roselle (Hibiscus sabdariffa) calyces and purple
roselle (Hibiscus sabdariffa) calyces and to determine the type of roselle
calyces which have potential as feed additive candidate on broiler. The phenol content was conducted using
visible spectrophotometry method with Folin Ciocalteau reagen, and the
antibacterial activity using agar well method for measuring clearing zone
againt Staphylocccus aureus and Escherichia coli. The results showed that
difference in solvent temperature (300C,
600C and 900C) of red and purple roselle calyces didn’t affect the phenol content, but the extract
10% of purple roselle calyces containing phenol content higher than the extract
of red roselle calyces. The difference
of solvent temperature didn’t affect the antibacterial activity, but extracts
10% of purple roselle calyces have antibacterial activity higher than red roselle calyces. Purple roselle calyces more potencial as feed additive.
