                                   Bakteri E.coli
• Mengganggu sistem pencernaan pada ternak dan
  manusia
• Pencegahan dan pengobatan dengan antibiotik

  Efek: Resistensi, residu antibiotik jika tidak tepat dosis, cara
      dan atau waktu/periode pemberian


  Alternatif solusi: penggunaan bahan yang bersifat alami


Alternatif bahan alam : Rumput Mutiara rumput siku siku (Hedyotis
    corymbosa (L) Lamk atau Oldenlandia corymbosa (L) Lamk)

                                Rumput Mutiara
Rumput mutiara  pada manusia 
• untuk mengatasi: gangguan pencernaan, kanker, radang usus
  buntu, mengobati penyakit akibat infeksi oleh mikroba (bakteri,
  protozoa dan jamur), keracunan
• untuk mengobati bisul, borok, bronchitis, pneumonia dan
  gondongan
• Mengandung senyawa biologis aktif : asam oleonat, ß-sitosterol,
  sitisterol, D-glukosida, asam ursolat, p-asam kumarat, flavonoid,
  tannin dan kumarin .
• Penggunaannya : seluruh bagian rumput mutiara baik segar
  maupun kering , sebagai obat luar, sebagai ramuan, secara
  tunggal atau bersamaan dengan tumbuhan lain.

                            Rumput Mutiara
Nurhayati dkk. (2006) mendeteksi adanya aktivitas
antibakteri pada rumput mutiara terhadap bakteri E. coli
 belum diketahui jenis, sifat dan struktur senyawa aktif
     dalam rumput mutiara tersebut yang dapat menghambat
     pertumbuhan bakteri E. coli.
belum diketahuinya apakah penggunaannya sebagai
     bahan additive bagi ternak dapat digunakan secara
     langsung atau berupa ekstrak, digunakan dalam campuran
     ransum atau air minum.
Berdasarkan hal tersebut maka telah dilakukan penelitian
     untuk mengetahui aktivitas biologis antibakteri dan
     kandungan kimia rumput mutiara berdasarkan data
     spektroskopi yang meliputi spektrum IR, 1H , 13C NMR. 5

                                  METODOLOGI

• Ekstraksi  isolasi
• Karakterisasi senyawa aktif  spektrum IR, 1H,
  13C NMR dan Kromatografi Lapis Tipis,

• Uji aktivitas antibakteri  media Nutrient Agar
  dan Mueller Hinton Broth

           Aktif sebagai antibakteri
• Keaktifan diduga karena adanya gugus keton
  (C=O) pada senyawa
• Berarti dapat dijadikan sebagai feed additive
   sebagai antibiotik
• Perlakuan ke ternak dalam bentuk ekstrak
  dari pelarut etil asetat  dicampur di ransum

                            Kesimpulan
Ekstrak etil asetat rumput mutiara (Hedyotis
corymbosa) mengandung senyawa tersier butil
isopropil keton yang aktif menghambat
pertumbuhan bakteri E.coli secara in vitro
                                      Saran
Ekstrak etil asetat rumput mutiara diuji cobakan
terlebih dahulu ke hewan percobaan sebelum
dicobakan ke ternak untuk melihat efek
toksisitas
