Sapi putih taro merupakan kelompok sapi yang unik dengan jumlah populasi yang sangat kecil dan hidupnya terbatas di hutan Desa Taro, Tegallalang. Populasi sapi putih ini semakin menurun dan dalam kondisi kritis. Karakterisasi breed adalah langkah utama dalam merancang manajemen dan program konservasi yang tepat. Untuk mendukung upaya konservasi, tujuan dari penelitian ini adalah untuk menilai profil fenotipik sapi putih taro berdasarkan pengukuran badan. Identifikasi profil morfometrik sapi putih taro dilakukan terhadap 24 ekor sapi putih taro dewasa, variabel yang diukur adalah panjang kepala, lebar kepala, tinggi badan, tinggi panggul, panjang badan, lebar dada, dalam dada, lingkar dada, dan lebar panggul.        Hasil penelitian menunjukkan bahwa nilai rata-rata panjang badan, tinggi badan, lebar dada, lingkar dada, tinggi pinggul, panjang kepala dan lebar kepala berbeda secara nyata antara jantan dan betina. Sedangkan dalam dada dan lebar panggul antara jantan dan betina, menunjukkan tidak ada perbedaan yang nyata. Hasil analisis komponen utama (AKU) menunjukkan komponen utama satu adalah panjang badan, tinggi badan dan tinggi panggul, sedangkan komponen utama dua adalah dalam dada. Hasil yang diperoleh dapat digunakan sebagai profil fenotif sapi putih taro dan penting bagi pembentukan strategi konservasi ke depannya dan strategi pengelolaan perkembangbiakan sapi putih taro untuk mencegah hilangnya keanekaragaman hayati di Indonesia.

Innards parts are more widely consumed by the public than the muscle parts, or more commonly known as beef. People are aware that the innards contain a lot of cholesterol, but they do not aware about the content of heavy metal lead. This research aims to study lead contamination levels in offal and beef muscle contaminated with lead. A total of five cows with known lead contamination were slaughtered to be examined for the levels of lead. Viscera taken part including the liver, lungs and intestines, which are the commonly consumed part. While the muscle tissues taken were from the costae muscles, which is the tissues with the most blood flow. Level of lead contamination in the innards and muscle tissues were checked using Atomic Absorption Spectrophotometry (AAS) method. The result of the examination was obtained as such: liver = 0.76 ± 0.25 ppm; lung = 1.11 ± 0.08 ppm; intestinal = 0.90 ± 0.29 ppm; and muscle tissues = 0.69 ± 0.13 ppm respectively. It was found that the innards contain more lead than the muscle tissues. It is concluded that the muscle part is safer for consumption than in the innards. It is also suggested that there are the needs for random checks in beef and the innards sold in the market, especially for the presence of lead contamination.

Biodiversitas 20: 671-675. This research was conducted to assess and characterize the genetics of Taro White cattle. Genetic characterizations of this cattle are essential to conservation and breeding program. A total of 18 samples and 4 pairs of microsatellite DNA markers (BM2113, BM1824, INRA023, and ETH225) were amplified by PCR and the products were run on 8% bis-Acrylamide gels. All microsatellite markers were successfully amplified with a mean allelic number of 3.25. Means of observed and expected heterozygosity were found to be 0,25 and 0,628. The Polymorphism Information Content (PIC) values ranged from 0.448 (BM1824) to 0.627 (BM2113) and fixation index were 0.620. The deviation from Hardy-Weinberg equilibrium revealed that Taro White cattle population exhibited significant deviations from Hardy-Weinberg equilibrium (HWE) and possessed a possibility of inbreeding. The microsatellite loci used or focused in the present study further validate their use for evaluation of genetic diversity of Taro White

Abstract. Susari NNW, Suastika P, Agustina KK. 2021. Molecular analysis of Taro and Bali cattle using cytochrome oxidase subunit I (COI) in Indonesia. Biodiversitas 22: 165-172. Cytochrome oxidase subunit I (COI) is one of the molecular markers often used as a differentiator with many advantages in phylogeny analysis, and it thus rarely undergoes substitution. This research was conducted to characterize the genetics of Taro and Bali (Bos javanicus) cattle. Blood from the animals was collected from the jugularis vein and amplified by PCR. The target area was COI with a primer that was successfully amplified, namely the forward BICOIF (5'-TTC-TCAACCAACCATAAAGATATTGG-3') and the reverse BICOIR fragment (5'-TAG-ACTTCGGGGTGTCCAAAGAATCA-3'). The PCR products' sequencing was carried out by phylogeny analysis using MEGA 6 software. The amplicon value that succeeded in electrophoresis was 710bp, while six polymorphic sites were obtained at base positions of 1, 300, 379, 675, 676, and 679. The haplotypes (Hap) obtained were 4, with a genetic distance that ranged from 0.000-0.001. The nitrogenous bases of the amino acid composition from the samples showed no significant difference. The phylogenetic tree (Tamura-Nei) classified the cattle into two clades with a genetic distance of 0.0005.

Tujuan dari penelitian ini untuk mengetahui pengaruh tepung daun kelor dalam pakan terhadap berat organ usus tikus putih (Rattus norvegicus). Tepung daun kelor diberikan secara oral pada 20 ekor tikus yang dibagi dalam 4 kelompok yaitu 1 kelompok kontrol dan 4 kelompok perlakuan dengan konsentrasi 0%; 2,5%; 5,0%; 10%  dan 20% masing-masing dengan 5 kali ulangan selama satu bulan. Tikus putih dibedah dan ditimbang organ ususnya. Penelitian ini menggunakan rancangan acak lengkap (RAL). Data yang diperoleh dianalisis dengan menggunakan ANOVA (analysis of varian),dan dilanjutkan dengan uji Jarak Berganda Duncan. Berdasarkan penelitian yang dilakukan diperoleh hasil bahwa tidak ada perbedaan berat organ yang signifikan. Kesimpulan:  Penambahan tepung daun kelor (Moringa oleifera) pada pakan tidak menyebabkan perubahan terhadap berat organ usus tikus putih (Rattus norvegicus).
