Abstract

Trenbolone acetate (TBA) is a growth hormone promoter which is implanted into animal to increase the body weight. The implantation of TBA in animal may cause the occurrence of residues of TBA and its metabolite (17-β-trenbolone). The presence of the residue might threat to human health. The aim of this research work was to study the presence of the residue of trenbolone in male Garut sheep which is implanted by TBA. The sheep were divided into 2 groups, those were D1 which were implanted by 40 mg TBA and D2 which were implanted by 60 mg TBA. One animal each from D1 and D2 were killed in the week 1, 2, 3 and 4 after implantation. And 24 hours before slaughtering the urine of D1 and D2 were collected using the metabolism cages. The samples for residue analysis were the organs such as liver, kidney, and the muscles around the implantation sites i.e inner and outer, upper front leg and upper back leg. The samples were extracted by organic solvents and analysed by HPLC. The residue of trenbolone occured in all samples of D1 and D2 which killed on 1 and 2 weeks after implantation. The residues occured on those which were killed 3 weeks after implantation were only in inner and outer samples. The residues in meat and organs were not detected in D1 nor D2 which were killed 4 weeks after implantation. The residue of trenbolone was also detected in the urine and still were detected in D1 and D2 which implanted by TBA for 4 weeks.   Key words : trenbolone acetate, 17-β-trenbolone, residue, sheep

Abstract

Trenbolone acetate (TBA) is a hormone being permitted to be used as growth promoters for livestocks in several meat-exporting countries. The presence of trenbolone residu in animal products might affect human health. The purpose of this study was to determine the distribution of trenbolone residue (TBA dan 17 ß-trenbolone) in tissues and urine of Onggole male calves. The implantation of 200 mg TBA as Finaplix-H® was done subcutaneously on the back side of the medial part of ear. Urine were collected periodically until 21 days post implantation. The animals were terminated on the day 21st post implantation. Urine, meat and organs were analysed for trenbolone residues. The results showed that TBA residues were detected in tissues of inner and surrounding areas of the implantation sites and liver with an average concentration of 11 ng/g, 2,1 ng/g and 1,6 ng/g respectively. The 17 ß-trenbolone residue was only detected in tissue of inner area of the implantation site at the average concentration of 8,2 ng/g. Meanwhile, none of the residues were detected in urine. Key Words: Residue, Trenbolone, Implantation

Abstract

Penelitian pengembangan petunjuk praktikum kimia berbasis POGIL bermuatan SWH ini didasarkan pada karakteristik peserta didik yang menyukai praktikum. Namun, petunjuk praktikum yang digunakan seperti buku resep, sehingga belum mampu mengarahkan peserta didik menemukan konsep materi. Penelitian ini bertujuan untuk mengetahui karakteristik dan kualitas petunjuk praktikum kimia berbasis POGIL bermuatan SWH yang dapat mengarahkan peserta didik menemukan konsep materi. Petunjuk praktikum berbasis POGIL bermuatan SWH dikembangkan dengan menggunakan model pengembangan 4-D yang terdiri dari tahap define (pendefinisian), design (perancangan), development (pengembangan), dan disseminate (penyebaran). Akan tetapi yang dilakukan dalam penelitian ini hanya terbatas pada tahap development. Subjek penelitian ini adalah 9 peserta didik dari MA Futuhiyyah 2 Mranggen Demak dengan tingkat pemahaman berbeda. Karakteristik dari petunjuk praktikum kimia yang dikembangkan antara lain: 1) Petunjuk praktikum disusun dengan tahapan-tahapan (orientasi, eksplorasi, penemuan konsep, aplikasi, dan penutup) yang dapat mengarahkan peserta didik menemukan konsep, 2) pertanyaan-pertanyaan dalam petunjuk praktikum bersifat rinci dan dikaitkan dengan kehidupan nyata peserta didik. Penilaian kualitas petunjuk praktikum kimia berbasis POGIL bermuatan SWH menggunakan validasi ahli dan respon peserta didik. Hasil penilaian validasi ahli materi mendapat kategori sangat baik (SB) dengan persentase 92,3%, sedangkan penilaian ahli media mendapat kategori sangat baik (SB) dengan persentase 90,83%. Respon peserta didik terhadap petunjuk praktikum menunjukkan kategori sangat baik (SB) dengan persentase 84,2%. Dengan demikian dapat dikatakan bahwa petunjuk praktikum berbasis POGIL bermuatan SWH layak digunakan sebagai panduan pelaksanaan praktikum di Laboratorium dan perlu diuji lebih lanjut pada kelas besar untuk mengetahui keefektifan produk dalam pembelajaran.

Abstract

Porous tri calcium phospate (TCP) has been prepared by starch-consolidation method using wheat as the pore formed agent. The purpose of this research is to investigate the influence of agitation rate and sintering temperature rate on physical, chemical, and mechanical properties of porous TCP. Wheat particles were mixed with TCP suspension then stirred for 1 hour. The slurry was dried in oven at 80˚C for 24 hours and at 120˚C for 8 hours. The green bodies were sintered at 2, 5, and 8˚C/minutes. The obtained green bodies shown shrinkage in the range 55.29-58.97%. The compressive strength of sintered bodies resulted was 0.73 MPa at 81.93% porosity and 2.89 MPa at 60.99% porosity.Keywords: tricalcium phosphate; porosity wheat particles; compressive strength
