Abstract

The aim of this research is to know the effect of siamih leaf ethanol extract (Ageratum conyzoides) on the growth of Staphylococcus aureus bacteria. The bacteria which is  used are obtained from the Microbiology Laboratory of the Faculty of Veterinary Medicine of Syiah Kuala University on isolate bacteria of the honey bear wound (Helarctos malayanus). Bacterial identification is done by culturing the isolate on lateral NA media then it is planted on MSA media and  staining Gram, catalase test and hemolysis test. The extraction is done by maceration with 96% ethanol solvent. Extract of Siamih leaf  is done by phytochemical test. The results of pythritic test of Siamih leaf show that Siamih leaf contains alkaloid compounds, steroids, terpenoids, flavonoids and tannins. The extract concentration which is used is 20%, 40%, 60% and 80%. Nergative control by using aquades and positive controls using Amoxicillin with three repetitions. The method used is disc diffusion or Kirby-Bauer method. The results show that Siamih leaf ethanol extract inhibit the growth of Staphylococcus aureus bacteria at concentrations of 20% (0,7 mm), 40% (1,4 mm), 60% (2,2 mm), and 80 % (3,0 mm). Thus it can be concluded that the extract of siamih leaf ethanol has inhibitory power to Staphylococcus aureus bacteria with low category.

Abstract

Penyakit tetelo (Newcastle disease) merupakan penyakit penting yang sangat mudah menular dan menyebabkan kematian tinggi pada unggas rentan. Penelitian ini bertujuan untuk mengetahui kejadian penyakit tetelo pada unggas yang dinekropsi di Laboratorium Patologi, Fakultas Kedokteran Hewan (FKH), Universitas Syiah Kuala (USK), Banda Aceh. Sampel penelitian dikoleksi dari 239 ekor cadaver unggas terdiri dari ayam pedaging/broiler, ayam petelur/layer, ayam kampung/buras dan unggas lainnya yang dinekropsi di Laboratorium Patologi FKH USK periode Juli sampai November 2019. Sampel yang dikoleksi yaitu trakhea, proventrikulus, seka tonsil dan otak. Sampel dipilih berdasarkan perubahan patologi anatomi diduga penyakit tetelo, selanjutnya dibuat sediaan histopatologi dan imunohistokimia dalam parafin blok. Hasil penelitian menunjukkan bahwa unggas yang dinekropsi dan mati akibat penyakit tetelo sebanyak 106 ekor, diduga fowl cholera 52 ekor, infectious bronchitis 25 ekor, avian influenza 22 ekor, colibacillosis 14 ekor, chronic respiratory disease 7 ekor, coccidiosis 5 ekor, infectious laryngotrcheitis 4 ekor, infectious bursal disease 2 ekor dan coryza 2 ekor. Simpulan dari penelitian ini bahwa cadaver unggas yang dinekropsi di Laboratorium Patologi FKH USK periode Juli sampai November 2019 sebanyak 44,4% (106/239) terdiagnosa mati akibat terinfeksi penyakit tetelo.
