This research was conducted at the Laboratory of Animal Produce Technology Faculty of Veterinary, Udayana University. Aims to determine the effect of papaya leaf extract, extract pineapple and ginger extract on the physical and organoleptic qualities of Bali beef through soaking. Variables measured to determine the physical properties of meat between meat pH and shrinkage of cooked meat, while the variables measured to determine the organoleptic quality of Bali beef among other examples: color, texture, taste, and smell of meat by panelist. The analyze used variance analysis, while experiment design used in this research is, Completely Random Design simple 4 treatment pattern 5 replication from Steel and Torie processed by Costas Statistic Method. Measurement of pH of the meat using pH meters, and the measurement of moisture content after cooking, is sought through the calculation of the percentage ratio of the difference between the weight of raw meat and the weight of meat after cooking. Conclusions and results of this study found that beef soaked in pineapple extracts showed: raw shrinkage, texture, color, taste, tenderness, and odor showed the best physical and organoleptic quality (P <0.05) compared to ginger extract and papaya leaf extract. While the physical and organoleptic qualities of beef soaked in extra papaya leaves show the worst indication.
Provinsi Nusa Tenggara Timur yang sering dijuluki sebagai lumbung sapi potong sapi perah dan kerbau.Dipandang dari sudut luas lahan yang dikuasai oleh rumah tangga antara lain lahan bukan pertanian, lahanpertanian yaitu lahan sawah dan lahan bukan sawah seluas. Penelitian dilakukan terbatas pada tiga buahkabupaten di NTT yaitu Kupang, Timor Tengah Selatan (TTS) dan Belu. Hasil penelitian menunjukkan hubunganmatematika antara lahan pangan (X) terhadap populasi sapi potong (Y) didapatkan: Y = 110,2324+1,7048X dan R2= 0,9838 (P<0,01). Hubungan matematika antara lahan perkebunan (X) terhadap populasi sapi potong (Y) adalah:Y=116,5996+2,4735X dan R2 = 0,9833 (P<0,01). Hubungan matematika antara lahan hortikultural (X) terhadappopulasi sapi potong (Y) tidak berbeda nyata (P>0,05). Nilai Location Quotien terbesar pada kerbau terdapatdi Kabupaten Kupang 6,2920, selanjutnya nilai LQ untuk kerbau di Kabupaten Timor Tengah Selatan sebesar4,9411 dan nilai LQ untuk kerbau di Kabupaten Belu sebesar 2,0762. Nilai LQ untuk sapi perah terbesar 1,4577ditemukan di Kabupaten Timor Tengah Selatan. Hasil penelitian ini dapat disimpulkan bahwa populasi ternakpotong terhadap lahan pangan dan perkebunan berhubungan positif sangat nyata (R2 = 0,98 P<0,01). Nilai LQternak kerbau terbesar berturut-turut didapatkan di Kabupaten Kupang, TTS dan Belu sehingga dapat dijadikansentra ternak kerbau untuk daerah-daerah lain di Provinsi NTT. Begitu juga untuk ternak perah di KabupatenTimor Tengah Selatan dapat dijadikan sentra ternak karena lebih besar dari satu.
The reproductive status of sows can be analyzed based on its level of ovarian activities characterized by thepresence of a number of follicles and corpus luteum in the ovary. The study of level of ovarium activity of sowsobserved the level of other reproductive performance. In this study, 100 ovaries in each 50 Landrace and bali sowswere divided into three groups of sows weighs slaughtering as of 60-70 kg (A); 71-80 kg (B); and 80-90 kg (C). Thevariables observed were dimensions of ovary, the number of follicles and corpus luteum in the right and left ovaries.Quantitative data with quantitative t-test determines the comparison on right and left ovary activities. It showedthat the average weight of right and left ovaries in landrace sows were 5.70 ± 1.22 g; 6.77 ± 0.96 g, and 4.89 ± 1.47g; 6.13 ± 1.46 g in bali sows. The average number of dominant follicles on the right and left ovaries of landrace sowswere 6.54 ± 1.81 f follicles; 9.78 ± 1.58 follicles, and on bali sows is 5.82 ± 1.90 follicles; 8.91 ± 1.50 follicles. Thenumber of corpus luteum on the right and left ovaries of the Landrace were 5.49 ± 2.22 CL; 8.16 ± 1.86 CL, and onbali sows is 5.27 ± 2.23 CL; 7.69 ± 2.22 CL. The t-test results showed that average number of dominant follicles andcorpus luteum in left ovary were significantly greater (P <0.05) compared to the right ovary. The highest percentageof dominant follicles and corpus found in sows of slaughter grouping 80-90 kg (C). It can be concluded that leftovary activity was more active than right ovary, and ovarian activity positively correlated with ovarian weight whichindicating ovarian activity in egg cell production and reproductive hormone.
Penggunaan A. tumefaciens untuk maksud mengintroduksi DNA albumin bunga matahari ke dalam sel tanaman kedelai didasari atas kemampuan alami dari A.tumefaciens untuk mentransfer suatu fragmen yang spesifik dari DNA plasmid (T-DNA ) ke dalam sel tanaman lalu berintegrasi pada genom sel tanaman inang. Hasil kloning gen albumin yang ditumbuhkan pada bakteri E.coli selanjutnya ditransfer ke A. tumefaciens LBA4404, melalui metode triparental mating. A. tumefaciens LBA4404 (pAL4404, pSW600 ) yang dihasilkan kemudian ditransformasikan pada tanaman kedelai secara in planta. Hasil analisis transformasi pada tanaman kedelai transgenic secara in planta dapat dibuktikan dengan analisis PCR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
