Deteksi Residu Hormon Trenbolon Asetat pada Sapi Siap Potong Impor asal Australia

Trenbolon asetat (TBA) merupakan hormon penggertak pertumbuhan yang diimplankan ke sapi untuk meningkatkan berat badan dan mengefisiensi konversi pakan. Penggunaan TBA dapat meninggalkan residu dalam urin dan dapat menyebabkan efek negatif. Tujuan dari penelitian ini adalah untuk menganalisis keberadaan residu TBA dalam urin sapi siap potong impor dari Australia. Ukuran sampel dihitung dengan menggunakan rumus deteksi penyakit dan sampel dipilih secara acak. Sebanyak 60 sampel dianalisis menggunakan enzim-linked immunosorbent assay (ELISA). Tes menunjukkan bahwa sebanyak 100% urin sapi siap potong dari Australia mengandung residu TBA dengan konsentrasi yang bervariasi. Konsentrasi residu TBA < 2 part per billion (ppb) terdeteksi pada 37 sampel (61,67%), konsentrasi residu TBA 2-4 ppb terdeteksi pada 7 sampel (7%), dan konsentrasi residu TBA > 4 ppb terdeteksi pada 16 sampel (26,67%). Hasil positif menunjukkan bahwa sapi potong asal Australia mengandung residu hormon trenbolon asetat (TBA).Kata kunci: ELISA, residu, sapi potong impor, trenbolon asetat, urin (Detection of Trenbolone Acetate Hormone Residues in Imported Slaughter Cattle from Australia)Trenbolone acetate (TBA) is a growth hormone promoter which is implanted into cattle to increase weight gain and feed conversion efficiency. The use of TBA can leave residue in urine and may cause negative effects. The objective of this research was to analyze the presence of the TBA residue in imported slaughter cattle urine from Australia. Cattle urine samples were collected from Animal Quarantine Installation. Sample size was calculated using the formula of detect disease and selected by random sampling. A total of 60 samples of cattle urine were analyzed for level of trenbolone acetate residues by using enzyme-linked immunosorbent assay (ELISA) method. The test showed that positive results in all of urine samples (100%) of slaughter cattle imported from Australia with variation in TBA residues concentrations. The concentration of residual TBA < 2 ppb were detected in 37 samples (61.67%), the residual concentration of TBA 2-4 ppb were detected in 7 samples (7%), and the concentration of residual TBA > 4 ppb were detected in 16 samples (26.67%). Total of 60 urine samples contained TBA residues. The presence of TBA residues with concentration above 4 ppb was 16 samples (26.7%). Positive results in the samples was indicated the Australian cattle contains trenbolone acetate (TBA) residue.Keywords: ELISA, residue, imported slaughter cattle, trenbolone acetate, urine
