Judul: Amplifikasi Gen Bar dan Gen Hpt Terkait Stabilitas Padi Mutan Serta Evaluasi Karakter Agronominya
Abstrak: Transposon Ac / Ds system containing an activation tagging constructs serves to develop a mutant plant that will produce changes in phenotype. This study aims to amplify the bar and hpt genes related to the stability of the mutant rice transposon Ac/Ds and observe the changes in phenotype based on the agronomy characters. Rice plant materials used for the study were six mutant T2 rice lines IR.64 (total 214 plants) and IR64 wild type rice as a control. The DNA of mutant plants was isolated and then amplified by PCR technique using primers specific for the bar and hpt genes. The results showed that the bar and hpt genes in the rice plant IR.64 mutant T2 with size were ± 700 bp and ± 600 bp. Evaluation of agronomic characters showed there were changes in these characters of mutant rice lines IR64 generation T2 that probably caused by the transposon insertion element containing 4x enhancer.

Judul: Deteksi Gen hpt dan bar untuk Uji Kestabilan Transposon Ac/Ds pada Padi Mutan IR64
Abstrak: Ac/Ds transposon system can be used to gain variety of mutant rice genotype and for identifying the function of mutant gen especially IR64 rice. However to obtain mutant plant that we want, stable transposon is required in order to avoid transposon movement to other chromosoms. This research has analyzed 26 samples of genom DNA of first generation (T0) plants with polymerase chain reaction (PCR) using bar and hpt primer also Southern hybridization analyzing. There is 26 genom DNA samples of second generation (T1) plants analyzed with PCR. PCR analyzation showed that transposon Ac/Ds is occur in all samples. Southern hybridization showed that 14 of 26 T0 plants contain single copy of T-DNA. Fourteen T1 generation plants contain stable Ds transposon based on the results of PCR analysis. This research proved that Ds transposon is stable because it was inherited on the next generation

Judul: Beberapa aspek anatomi alat sirkulasi ruang dada kancil
Abstrak: Telah dilakukan penelitian dengan menggunakan 10 ekor kancil dewasa jantan dan betina dengan tujuan untuk menge- tahui beberapa aspek anatomi alat sirkulasi di dalam ruang dada, meliputi jantung, pembuluh darah yang keluar dan ma- suk jantung serta ukuran-ukuran jantung. Kancil merupakan ruminansia terkecil di dunia, hidup di daerah tropika India, Thailand, Malaysia dan Indonesia bagian barat. Hewan ini dilindungi dan mempunyai prospek yang baik untuk hewan penelitian maupun dibudidayakan. Hasil penelitian menunjukkan bahwa berat jantung rаta-rata adalah 0.69% dari berat rata-rata kancil. Dan ini mirip pada jantung kuda dan anjing. Bentuk jantung lonjong seperti halnya ruminansia. Demikian pula letaknya di dalam ruang dada seperti pada ruminansia dengan adanya Ligamentum sternopericardiacum. Di dalam ventrikel kanan membersit sebuah Musculus (M.) papillaris dari dindingnya dan tiga sampai empat Musculi (Mm.) papillares dari Septum interventriculare. Hanya dua buah Mm. papillares yang berukuran besar dibersitkan dari dinding ventrikel kiri. Percabangan Arteri (A.) coronaria sinistra lebih dominan dari pada A. coronaria dextra. Sedangkan A. sub clavia sinistra dicabangkan langsung dari aorta di dorso- caudal pembersitan Truncus (Tr.) brachiocephalicus…
